I am working on Infragistics Grid in MVC and want to do some customization in it.
The issue is that data which I am showing is different than the inputs I am taking from the user (the editors in row editing/adding mode). There is additional processing needed to be done before displaying in a grid.
Infragistics grid provides a good mechanism to show the JSON object array which nice UI and events which works fine for me. The problem comes when I want to Edit a particular Row or Add New. For this Infragistics provides its own UI for it. Or in case we want to customize it, it doesn't provide much room to do so. It just allows providing a template for columns like the following:
<script id="rowEditDialogRowTemplate1" type="text/x-jquery-tmpl">
<tr class="tableBackGround">
<td class="labelBackGround"> ${headerText}
</td>
<td data-key='${dataKey}'>
<input />
</td>
</tr>
</script>
But I want to provide an entire template which will have my custom form and form elements.
I want a simple Infragistics Grid which will just show the data. If I click Add New within the grid then it will load my dialog.
If I double-click any row it will again open my dialog where I can edit the things. Later, once I save the data, I'll make a server trip and refresh the grid accordingly.
To summarize
I want to provide my own custom Form for Add and Edit in Infragistics Grid. And I'll take care of reloading the Grid after saving the data.
Reference : Infragistics Grid
Please help me to get this done!
You have found the correct API reference - in the 'options' tab look for the rowEditDialogTemplate option.
The use of the default Row Edit Template (yes, it can be used for adding rows as well) is shown in the official sample.
You can also find out more about it in the help topics: Row Edit Template and Configuring Row Edit Template.
Also, in the Infragistics forums you can find additional info on how to utilize the igGridUpdating feature's API methods (addRow and updateRow for example) with your fully custom form for row adding and editing.

I'm using select2.full.js
I'm not using any require.js to help me pull in modules, I'm basically using my know how from everything I learned in v3.5
I've been trying countless of hours, wrapping my head around this, but I have no idea how to make ajax cascading dropdowns.
Example: You load up the page, there is the first select2 dropdown that pulls data using ajax automatically (you don't enter anything.. data is there on the page load from the server), a default value is selected. Since that default value is selected, the second select2 drop down will use that value to make an ajax call to populate its own list. Now, when I select another value in the first select2 dropdown, the second select2 dropdown will reflect those changes with the new dataset.
What I've able to come up with was a 3 dropdowns that you can populate on a page load, but when you do any ajax request, the dropdown data doesn't change.
It's been two years since I used select2, and the library keeps changing, the documentation keeps changing, I'm at my wits end with this library. But I feel drawn to it by the bootstrap support, and the look and feel. The functionality, the way to implement things, the documentation is just so unbelievably awful.
I don't have any useful code at all, I've been pulling, plugging, modifying, etc.. and now I'm moving to my hair and teeth.
ANY useful example to do this would be awesome.
Just found my answer..
I was using the templating:
<select id="test">
<option value="1">1</option>
<option value="2">2</option>
</select>
to:
data = [{id: "1", text: "1"}, {id: "2", text: "2"}];
<input id="test" type="hidden" />
and just kept my jquery on select2 the same. So it was really just a change in the templating from to that solved it.
However, the only downside to this is that when you are refreshing new data from these drop downs, the highlighted (selected value) is always the first item in the drop down list, even though that's not the selected value shown in the dropdown.
Here is a small code snippet to make Select2 (v4.x) cascading dropdown - https://gist.github.com/ajaxray/187e7c9a00666a7ffff52a8a69b8bf31
Using this module, options of a select2 list box will be loaded/refreshed by ajax based on selection of another select2 list box.
Example use -
new Select2Cascade($('#province'), $('#district'), 'path/to/geocode', {type:"district", parent_id: ''});
Selected value of parent select2 listbox will be set to the parent_id of the data object before ajax call.
I've been working with Knockout.js for some time now but only recently I've started to integrate jqueryUI animations for the sake of a better user experience. I'm seeing some issues trying to use the animation bindings on the tr elements inside a table tag. When I use the "visible" binding to hide and show each element it works just fine but when I attempt to animate the showing hiding of each element it only seems to apply to the first row in the table. I've attempted this using various methods. I've attempted using the knockout foreach template 'afterAdd' option as described here:
http://knockoutjs.com/documentation/foreach-binding.html#note_5_postprocessing_or_animating_the_generated_dom_elements
I've also created a custom binding and attempted to use that on each of the table row items with the same results.
Lastly I attempted to use the plugin found here:
http://www.codecoding.com/knockout-plugin-visibility-bindings-with-jqueryui-effects/
And again, it only appears to work on the first element of the table. Now before attempting to rewrite my HTML to use divs and spans rather than the tables I wanted to see if anybody else has seen these sorts of issues with knockout in the past. The relevant chunk of HTML is this:
<table class="tab_table table_a">
<tbody data-bind="foreach:featuredMenuItems,visible:showFeatured">
<tr data-bind="fadeVisible:readyToShow, click:function(){$root.showProductOptions($data);}">
<td class="td_large" data-bind="css:{td_select:itemInCart};"><span class="inCart_delete" data-bind="css:{display_IB:itemInCart},click:removeFromCart,clickBubble:false"><i class="fa fa-times-circle"></i></span><span data-bind="text:name"></span></td>
<td class="td_last" data-bind="css:{td_select:itemInCart},text:lineItemCost"></td>
</tr>
</tbody>
</table>
I would paste the ViewModel code in here as well but it is a rather large view model and the relevant part to this is just a simple "readyToShow" observable set to either true or false. Whenever this table is being shown the "readyToShow" values of each of the objects in the observableArray containing the table items is being set to true over time using a timeout so as to show a cascading effect when the table is shown.
I would really appreciate any help you guys could provide. Thanks!
this is phani kumar,
Actually, i am writing one page to show product details. In that i written code to display the
productid list in jsp page with the help of and tags
. but the main problem is, based on the selection of productid, i trying to show the product details(productname, productcost, productstock..like).But i am facing problems to work this.
I am trying it with javascript, but because of struts html taglibrary, i am getting problems here, could u please give me solutions to resolve this problem anyone.
and can anybody tell how to get dropdown selection value into javascript(if we are using tag library in struts)
How are you using javascript to create your view? You should be able to use
<logic:iterate>
to traverse your product collection, then
<bean:write .../>
to display information from each product.
<html:select>
will create a dropdown in your form. Use
<html:option>, <html:options>, or <html:optionsCollection>
to populate each item in the dropdown.
I am having a html dropdown
<select id="ExternalIp" onchange="externalIpchange()"></select>
I bind the data to dropdown through jquery and a I am passing data from controller which is working properly. I want to change the look and feel of the dropdown so I called a function
$("#ExternalIp").selectbox();
Now the look and feel of drop down is changed but it is not showing the data which I bind to dropdown. I am not getting what is the problem. Plz help
It appears as if the jQuery plugin you are using resets the values bound to the select list.
Look for a method provided within your jQuery plugin to rebind the data which you earlier attached with jQuery or style your element first and then try binding the values.
Cheers!!!
I'm building a grid in ASP.NET MVC and I have the following issue:
Above the grid i have a column selector which lets people customize the columns being shown. This is a form with a submit button so that people can add/remove multiple columns at once without going trough multiple postbacks.
Below the grid I have paging. This is paging trough actionlinks (a href's).
alt text http://thomasstock.net/mvcget.jpg
What happens when a user add/removes columns is that the form gets submitted to http://localhost:56156/?columnsToDisplay=EmployeeId and ofcourse the grid jumps back to page 1. I'd like to keep the grid on the page the user was currently on. So I need a way to include the current querystring parameters into the form's action attribute.
The other way around too: I need a way to do the same with actionlinks. But this is less necessary as I could always replace the a href's with buttons and put them in a form. But I'd rather not do that.
I'm looking for a solution without javascript! I can do it myself in javascript, but I'd like my grid to work perfectly on javascript-disabled browsers.
Any help is appreciated.
Edit:
Oh yeah, to make it a bit harder, I'm also looking for a solution without cookies/session variables. :-)
You need to add the line below into your column selector form
<input type="hidden" name="page" value="<%=Request.QueryString["page"]%>" />
