How to add Image column into Kendo UI Grid - asp.net-mvc

I have one grid like this :
#(Html.Kendo().Grid<ProductViewModel>()
.Name("Grid")
.Columns(columns =>
{
**columns.Bound(c => c.Logo).ClientTemplate();**
columns.Bound(p => p.Title);
columns.Bound(p => p.Category);
columns.Bound(p => p.SupplierName);
columns.Bound(p => p.SupplierContactName);
columns.Bound(p => p.IsDeleted);
columns.Bound(p => p.TimeStamp).Format("{0:yyyy/MM/dd HH:mm}").EditorTemplateName("DateTime"); ;
//columns.Command(command => { command.Edit(); command.Destroy(); }).Width(220).Title("Command");
//columns.Command(command => { command.Edit(); command.Destroy(); }).Width(250);
})
.Pageable()
.Scrollable()
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.ID))
.Read(read => read.Action("EditingCustomValidation_Read", "Product"))
)
And I have one action like this for Showing image :
public FileContentResult Photo(int id)
{
return new FileContentResult(db.Products.Find(id).Logo, "image");
}
What should I write in my ClientTemplate for calling this action sending productid an showing products logo?

Please you can try like this...
columns.Bound(c => c.Logo).ClientTemplate("<img src='" + Url.Content("~/ImagePath/") + "#=ImageUrl#' alt='#=Name #' Title='#=Name #' height='62' width='62'/>");

One of my colleague ran into same issue and we posted question on telerik forum Bind image path to a controller function in Kendo Grid and they responded as below.
I think instead of your controller returning a string with the URL of the image it might be easier for it to just return the image itself. Some thing like this post on stackoverlow
That way you can just have your template point the src property of the img html element to this controller action that would presumably take as parameter something to pinpoint the corresponding image file to each row element.

Telerik Kendo Grid Doesn't Display Value Properly

i'm new to kendo UI and currently learning about custom editor.
My Problem is i managed to get my editor template working in edit mode and populate the data just fine, but somehow it won't save the value to the display grid
I Retreive all my data from API.
UPDATE:
i've managed to properly save the value from the custom editor template to the controller and it works just fine, but using clientTemplate won't display the correct value from what i select in the dropdown, and only show a string
DropDown Only Display A String
my setup code is like this
#( Html.Kendo().Grid<SalesOrderDetailVM>()
.Name("list-detail")
.Columns(columns =>
{
columns.Bound(c => c.Product).ClientTemplate("\\#=Product.ProductId\\#").Title("Products");
columns.Bound(c => c.Quantity);
columns.Bound(c => c.UnitPrice);
})
.Editable(GridEditMode.InCell)
.ToolBar(tool =>
{
tool.Create();
tool.Save();
}
)
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.Batch(true)
.Model(model =>
{
model.Id(p => p.ProductId);
model.Field(p => p.Product);
})
.Create(act => act.Action("DetailCell_Create","SalesOrder"))
)
)
DDLProduct.cshtml:
#model AAF.WEB.MVC.ViewModels.ProductVM
#(
Html.Kendo().DropDownListFor(m => m)
.DataValueField("ProductId")
.DataTextField("ProductName")
.OptionLabel("Select Product")
.BindTo((System.Collections.IEnumerable)ViewData["products"])
)
Edit Mode
DisplayMode / Out of Product Edit Mode
Use template method to acheive dropdown with kendo grid.
GridForeignKey.cshtml - it should placed in shared folder or EditorTemplates
#model object
#(
Html.Kendo().DropDownListFor(m => m)
.BindTo((SelectList)ViewData[ViewData.TemplateInfo.GetFullHtmlFieldName("") + "_Data"])
)
In your kendo grid please change like below
#( Html.Kendo().Grid<AAF.WEB.MVC.ViewModels.SalesOrderDetailVM>()
.Name("list-detail")
.Columns(columns =>
{
columns.Bound(c => c.Id)
columns.ForeignKey(c => c.ProductId, (System.Collections.IEnumerable)ViewData["Products"], "ProductId", "ProductName").Title("Products");
columns.Bound(c => c.Quantity);
columns.Bound(c => c.UnitPrice);
})
.Editable(GridEditMode.InCell)
.ToolBar(tool =>
{
tool.Create();
tool.Save();
}
)
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
)
)
You can set the products data to view data. using this method you can save the product id.
Thanks
Okay after i frustrated for many hours, finally found the solution
the solution is to add a defaultvalue to the passed model in the grid
.Model(model =>
{
model.Id(p => p.ProductId);
model.Field(p => p.Product).DefaultValue(
ViewData["defaultProduct"] as ProductVM
);
})
and pass the data from the controller
// Function that get data from API
ViewData["products"] = products;
ViewData["defaultProduct"] = products.First();

How to pass the model of a row from Kendo Grid to an editable template

I have a Kendo Grid which has a popup editable template,
If possible i would like to pass the model (the model of the row, or at least its Id) to the editable template
Grid
#(Html.Kendo().Grid<Client>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(c => c.Name).Width(140);
columns.Bound(c => c.Status);
columns.Bound(c => c.ProcesingStyle);
columns.Bound(c => c.ArchiveDays);
columns.Command(command =>
{
command.Edit().Text(" ");
command.Destroy().Text(" "); ;
}).Width(90);
})
.ToolBar(toolbar => toolbar.Create().Text("New"))
.Editable(editable => editable
.Mode(GridEditMode.PopUp)
.TemplateName("Client").AdditionalViewData(new { Client = Model })
.Window(w => w.Title("Site")))
.HtmlAttributes(new { style = "height: 380px;" })
.Scrollable()
.Sortable()
.Selectable()
.Resizable(resize => resize.Columns(true))
.Reorderable(reorder => reorder.Columns(true))
.Events(events => events.Change("onChange"))
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(true)
.ButtonCount(5))
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("Get", "Clients"))
.Model(model => model.Id(p => p.Id))
.Create(update => update.Action("Create", "Clients"))
.Update(update => update.Action("Update", "Clients"))
.Destroy(update => update.Action("Destroy", "Clients"))
)
)
Template
#model Client
#(Html.Kendo().ComboBoxFor(m => m.Plan)
.DataTextField("Name")
.DataValueField("Id")
.Placeholder("Select Plan...")
.HtmlAttributes(new { style = "width:300px" })
.Filter(FilterType.Contains)
.MinLength(3)
.DataSource(source =>
source.Read(read =>
read.Action("GetPlans", "Plans",new {ClientId = Model.Id}))))
Everything works fine except i need to use the Id of the row/model inside the template, in particular , i need the to pass the model.Id (which is the id of the model of the row), to the action on the Combobox in the template, so i can filter the data correctly
This is the offending line in the grid,
.TemplateName("Client").AdditionalViewData(new { Client = Model })
The result is the Model inside the template is always null, im not sure how to pass the data i need to the template
Is there anyway i can do this, or should i be looking at a different approach?
The way I got around this was to put a JavaScript function in the original view as seen below:
function getClientId() {
var row = $(event.srcElement).closest("tr");
var grid = $(event.srcElement).closest("[data-role=grid]").data("kendoGrid");
var dataItem = grid.dataItem(row);
if (dataItem)
return { clientId: dataItem.Id }
else
return { clientId: null }
}
And reference it from my editor template:
.DataSource(source => source.Read(read => read.Action("GetPlans", "Plans").Data("getClientId"))))
Note : I'm pretty sure you cant run JavaScript from a EditorTemplate so it needed to be housed in the original view.
I know this is a really old question, but for those who are wondering why this doesn't work:
.TemplateName("Client").AdditionalViewData(new { Client = Model })
This code doesn't work because the only data you can pass through this method is static data. You can pass specific strings or numbers, like "Hello World", and that would work fine. For dynamic data with kendo, I've learned that it really depends on the situation, and your solution here works well.

Kendo UI Grid Read Action is not being called when hosted on Azure

Ive seen lots of traffic regarding this issue so I thought I would add my own spin. Everything works as expected on my dev machine. But when I deploy to Azure, the read action on the grid is no longer posted. instead its posting to the url of the page.
Here is my grid
#(Html.Kendo().Grid<HondaPERebates.Model.Models.ClaimModel>()
.Name("grid")
.Groupable()
.Columns(columns =>
{
columns.Bound(p => p.RebateProgramId).Hidden();
columns.Bound(p => p.Status).ClientTemplate("<span class='#=GetClass(Status)#'>#=Status#</span>").Width(100);
columns.Bound(p => p.SellingDealerNo).Width(100);
columns.Bound(p => p.SerialNumberSuffix).ClientTemplate("<span>#=SerialNumberPrefix#-#=SerialNumberSuffix#</span>").Width(150).Title("Serial Number").Filterable(false);
columns.Bound(p => p.SubmittedDate).Format("{0:MM/dd/yyyy}").Width(75);
})
.Pageable()
.Sortable()
.Resizable(resize => resize.Columns(true))
.Selectable()
.Filterable()
.Scrollable(scrollable => scrollable.Virtual(true).Height(630))
.DataSource(dataSource => dataSource
.Ajax()
.Model(model =>
{
model.Id(p => p.RebateProgramId);
})
.PageSize(65)
.Read(read => read.Action("_GetClaims", "Rebates").Data("grid_Parameters"))
)
.Events(events => events.DataBound("onDataBound")
)
)
and the controller
public ActionResult _GetClaims(int rebateProgramId, [DataSourceRequest] DataSourceRequest request)
{
var email = this.HttpContext.User.Identity.Name;
var list = _manager.GetClaimsByEmail(rebateProgramId, email);
return Json(list.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
}
and the js that gets invoked to get extra parms
function grid_Parameters() {
var RebateProgramId = $('#RebateProgramId').val();
return { RebateProgramId: RebateProgramId };
}
I my case the Action method was not getting called (example : HierarchyBinding_Employees).
I changed the Name to GetHierarchyDataForEmployees and it worked for me :).

Kendo MVC Grid Within a Window DataSource Read

I'm trying to populate a kendo grid within a kendo window in MVC and am unable to find what is wrong. The window is created, and the grid is created within the window... however the DataSource's Read method is never called.
Window:
#{
Html.Kendo().Window()
.Name("DListing")
.Title("Listing")
.Draggable()
.Resizable()
.Width(1000)
.Height(500)
.Visible(true)
.Modal(true)
.Actions(actions => actions
.Maximize()
.Close())
.LoadContentFrom("Dispatch", "Listing", new { Number = #ViewBag.Number })
.Render();}
The Dispatch method in the Listing controller returns back a partial view that contains the grid.
Grid:
#(Html.Kendo().Grid(Model)
.Name("Grid")
.Events(events => events.Change("onChange"))
.HtmlAttributes(new { style = "height:400px;" })
.Columns(columns =>
{
columns.Bound(p => p.Number);
columns.Bound(p => p.DateTime).Format("{0:MM/dd/yyyy hh:mm tt}");
columns.Bound(p => p.Location);
columns.Bound(p => p.Name);
columns.Bound(p => p.Elapsed_Hours);
})
.Groupable()
.Pageable(pageable => pageable
.Numeric(false)
.Input(true)
.PageSizes(new[] { 5, 10, 25 }))
.Sortable()
.Scrollable(scrollable => scrollable
.Virtual(true))
.Filterable()
.Selectable(selectable => selectable
.Mode(GridSelectionMode.Multiple))
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(13)
.Sort(sort => { sort.Add(p => p.DateTime).Descending(); })
.Model(model => { model.Id(p => p.Number); })
.Read(read => read.Action("Listing_Read", "Listing", new { Number = #ViewBag.Number })))
)
Listing_Read Method:
public ActionResult Listing_Read([DataSourceRequest] DataSourceRequest request, int Number)
{
return Json(GetListing(branchNumber).ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
}
Also, it should be noted that I went through and verified that the viewbag data is available for both the window and later on in the grid.
For a little more back info, I initially had the grid on it's own page and it was able to call the read method and populated with the data with no issues. After moving it to populate in the window is when this became a problem.
Monitoring the http requests, the grid never attempts to call the read method (so the request isn't failing). I tried manually refreshing the datasource after the window has loaded thinking that might force the call, but that doesn't call the read method either.
I've been scratching my head on this one for a few hours now trying different things, hoping someone can spot what the problem is :)
Here's what worked for me:
1) View (~/Views/Home/Index.cshtml)
#(Html.Kendo().Window()
.Name("myWindow")
.Title("Title")
.Actions(actions => actions.Pin().Minimize().Maximize().Close())
//.Content(Html.Partial("gridCat").ToHtmlString())
.LoadContentFrom("Load_gridCat", "Home")
)
2) Partial View (~/Views/Shared/gridCat.cshtml)
#(Html.Kendo().Grid<TelerikMvcApp1.Models.Category>()
.Name("CategoriesGrid")
.Columns(columns =>
{
columns.Bound(c => c.CategoryID).Title("Category").Width("10%");
columns.Bound(c => c.CategoryName);
columns.Bound(c => c.Description);
})
.Filterable()
.Pageable()
.Sortable()
.Scrollable()
.DataSource(dataSource => dataSource
.Ajax()
.Model(model => model.Id(p => p.CategoryID))
.Read(r => r.Action("Categories_Read", "Home"))
)
.HtmlAttributes(new { style = "height:250px" })
)
3) Controller (~/Controllers/HomeController.cs)
public ActionResult Load_gridCat()
{
return PartialView("gridCat");
}
public ActionResult Categories_Read([DataSourceRequest]DataSourceRequest request)
{
using (var ctx = new NWindContext())
{
IQueryable<Category> categories = ctx.Categories;
DataSourceResult result = categories.ToDataSourceResult(request);
return Json(result, JsonRequestBehavior.AllowGet);
}
}

add ClientTemplate to custom command in kendo grid UI

Here is my kendo grid code:
#(Html.Kendo().Grid(Model)
.Name("paymentGrid")
.Columns(columns =>
{
columns.Bound(p => p.AccountName).Title("Account Name");
columns.Bound(p => p.Active).Title("Active").ClientTemplate("<div>#=Active ? 'Active' : 'Inactive'#</div>");
columns.Command(command => command.Custom("DeActivate").Click("deActivatePaymentAccount").Text("DeActivate")).Title("DeActivate");
})
.Filterable()
.Sortable()
.Pageable(paging => paging.Enabled(true).PageSizes(true).Messages(messages => messages.Empty("No accounts found")))
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.Model(model =>
{
model.Id(p => p.AccountId);
})
.Update(update => update.Action("EditAccount", "Account"))
)
)
Question:
How do I add a client Template to my Custom Command (Deactivate) so I can toggle the text on the button based on whether the account is active or not?
I think that the best way to change the button text is to do this in the javascript function bound to the click event :
function deActivatePaymentAccount(e) {
var $btn = $(e.target);
$btn.text() === "DeActivate" ? $btn.text("Activate") : $btn.text("DeActivate");
// some other code here
}
