I've lost my C# Panel Controls....
the asp for my panel is
<asp:Panel ID="pnlSett1" GroupingText="Contra Account 1" runat="server"
Width="400" >
</asp:Panel>
I've set up the controls in code behind using
Label lblCompanyNumber = new Label();
lblCompanyNumber.Text = "ABCDEF";
lblCompanyNumber.ID = "CompanyNumber";
pnlSett1.Controls.Add(lblCompanyNumber);
But after the panel is populated and the user clicks on the ContraUpdate button (postback) ---
protected void btnContraUpdate_Click(object sender, EventArgs e)
Control pnlCompanyNumber = pnlSett1.FindControl("CompanyNumber");
it can't find the control....Null value returned
Any ideas, i've tried putting the Find Control after the initial Control Add to prove the FindControl is correct and it is, but then I tried it on the PageLoad on the way back in, and that brings back Null value as well......

I am doing some integration tests, and I have replaced some tables with a grid. At this moment, I have some visible columns by default and other columns are hidden as follows:
column6.setHidable(true);
column6.setHidden(true);
Now I am trying to do some integration tests. For getting the grid, I can use the method (is the only grid present in this view):
$(GridElement.class).first();
This works fine. But for my test (with Vaadin Testbench), I need to check some values that are inside the hidden columns of the grid. I am talking about this button:
I have tried to use the Vaadin debug console to get the name of the button that allows the user to show/hide columns, but the debug console only can select the entire grid element, not this menu.
Also I have check if inside the GridElement exists any kind of already implemented method that give me access to this menu without any success.
Usually, chrome developer tools (or similar for firefox and ie / edge, etc) is your best friend in such cases. So far I'm not aware of anything dedicated for that particular button. However you can workaround this limitation by selecting the items which compose this feature by their specific classes:
The below test method shows a quick implementation which should give you a starting point:
public class GridManipulationTest extends TestBenchTestCase {
#Before
public void setUp() throws Exception {
System.setProperty("webdriver.chrome.driver", "D:\\Kit\\chromedriver_win32\\chromedriver.exe");
setDriver(new ChromeDriver());
}
#After
public void tearDown() throws Exception {
// TODO uncomment below after checking all works as expected
//getDriver().quit();
}
#Test
public void shouldOpenGridColumnVisibilityPopupAndSelectItems() {
// class for the grid sidebar button
String sideBarButtonClass = "v-grid-sidebar-button";
// class for the sidebar content which gets created when the button is clicked
String sideBarContentClass = "v-grid-sidebar-content";
// xpath to select the item corresponding to the necessary column
// there are perhaps more "elegant" solutions, but this is what I came up with at the time
String columnMenuItemXpath = "//*[contains(#class, 'column-hiding-toggle')]/span/div[text()='Name']";
// open the browser
getDriver().get("http://localhost:8080/");
// get the first available grid
GridElement firstGrid = $(GridElement.class).first();
// look for the grid's sidebar button and click it
firstGrid.findElement((By.className(sideBarButtonClass))).click();
// the sidebar content is created outside the grid structure so don't look for it using the grid search context
WebElement sidebarContent = findElement(By.className(sideBarContentClass));
// look for the expected column name and click it
sidebarContent.findElement(By.xpath(columnMenuItemXpath)).click();
}
}
And of course what it looks like in action
I have a asp:Wizard control in my Web Application.I need to be able to print at any step within the wizard , and print all steps up to that step not just the current step.
I've added a print button to every step page , and tried to call the javascript:window.Print(), but only the current step gets printed.
How do i get all the steps to print in 1 page?
i'd like to try and get this working in javascript first before i go down the PDF route . I've tried doing somehting like this :
protected void Page_Load(object sender, EventArgs e)
{
StringWriter sw = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(sw);
this.WizardStep2.RenderControl(tw);
string wizardHtmlContent = sw.ToString().Replace("\r\n", "");
string printScript = #"function printDiv(printpage)
{
var headstr = '<html><head><title></title></head><body>';
var footstr = '</body>';
var newstr = printpage;
var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr+newstr+footstr;
window.print();
document.body.innerHTML = oldstr;
return false;
}";
this.Page.ClientScript.RegisterStartupScript(this.GetType(), "PrentDiv", printScript, true);
this.Button1.Attributes.Add("onclick", "printDiv('" + wizardHtmlContent + "');");
}
and for the aspx:
<form id="form1" runat="server">
<div>
<asp:Wizard ID="Wizard1" runat="server">
<WizardSteps>
<asp:WizardStep ID="WizardStep1" runat="server" Title="Step 1">
step1
</asp:WizardStep>
<asp:WizardStep ID="WizardStep2" runat="server" Title="Step 2">
step2
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
</form>
But i'm getting a missing runat=server error on line 3 , when i attempt to render the wizard control , so i think i may need to create a new window, then output the string before i print it , but cant seem to get that working ...Anyone any ideas ?
i have found a solution for my problem , i didnt manage to accomplish it client side , but ive managed to solve it server side which is better than going down the PDF route which i didnt want to do.
I found a great article here :
Printing in ASP.NET
which i ammended to print all steps of my wizard control in one go. thanks for all your help.
The javascript print method you're already using will work if you put the wizard steps in to a single page so they all render ...
the other way I guess is to simply browse to each step and hit your print button.
the way I would do it is use something like pdfsharp and give it the markup generates by each step and tell it to create a pdf page for each steps worth of markup ... from there the user has a pdf doc which they can simply view save or print using their usual pdf viewer.
The problem is that the javascript method is using a dom based api call to ask the browser to print the page which of course ultimately means you can only print the wizard step you're currently looking at ... using the pdf method means the user can preview the expected print out before printing and you have more control over what's printed.
It does require a bit more code though ...
pdfsharp can be found here: http://www.pdfsharp.net/Downloads.ashx
As you can see its free and open source.
Morning - I'm having a little problem.
I have an autocomplete extender textbox where a user types in words and suggestions are provide. Should the term be rather generic, a list appears and the user can scroll up or down using the mouse wheel with no problems at all.
However, if the user attempts to click on the scroll bar and scroll through the list, it fires the textchanged event - which I don't want it to do.
This event should only fire once the user has actually selected the appropriate product from the list supplied.
I can set the autopost back of the text file off which has the desired effect but I do require the post back to be performed once the user selects a suggestion.
Does anyone know how I can get around this?
I managed to find a resolution.
Stick this in the page load event:
string contactPostBackFunction = null;
contactPostBackFunction = Page.ClientScript.GetPostBackEventReference(this.tbxProdAC, "", false);
string contactPostBackScript = null;
contactPostBackScript = string.Format("function postBackOnContactSelectedFromDropDown() {0} {1} {2}", "{", contactPostBackFunction, "}");
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "contactPostBackScript", contactPostBackScript, true);
And have this in your Autocomplete extender properties:
OnClientItemSelected="postBackOnContactSelectedFromDropDown"
this problem is driving me really mad.
In an Asp.Net-application, I have two DropDownLists, DropDownStore and DropDownCampaign.
<asp:DropDownList ID="storeDropDown" AppendDataBoundItems="true"
AutoPostBack="true" DataSourceID="storeSqlDataSource"
DataTextField="Name" DataValueField="StoreId"
runat="server" OnSelectedIndexChanged="storeDropDown_SelectedIndexChanged">
<asp:ListItem Value="">Choose a store</asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID="campaignDropDown" DataSourceID="campaignSqlDataSource"
DataTextField="Name" DataValueField="CampaignLevelId"
AppendDataBoundItems="true" runat="server">
<asp:ListItem Value="">Choose a campaign</asp:ListItem>
</asp:DropDownList>
As you can see, they are both bound to SQLDataSources.
The SQLDataSource for the second DropDownList looks as follows:
<asp:SqlDataSource ID="campaignSqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:AFPMAdManagerConnectionString %>"
SelectCommand="SELECT [CampaignLevelId], [Name] FROM [CampaignLevel] where [StoreId] = #StoreId">
<SelectParameters>
<asp:ControlParameter ControlID="storeDropDown" Name="StoreId" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
so that the second DropDownList is bound, when the user chooses an entry of the first
DropDownList.
This works well. But when I set the value of the first DropDownList programmatically,
the second DropDownList is bound twice:
protected void Page_Load(object sender, EventArgs e)
{
storeDropDown.SelectedValue = "someStore";
}
Why?
It's being told to bind twice. It binds on the original value of the first dropdown (since that's the controlID governing it), and then when you set it in Page_load event it binds it again.
I would recommend binding it to a label with visible property set to False. Then on the first dropdown selectedindex changed, set the text property of the label.
While I don't know the exact reason for the double binding, your best bet might be to set an OnDataBinding handler for the second list, set a breakpoint in it, and examine the call stack in both places. That'll tell you why the framework is binding that list, both times.
Depending on how sensitive to performance you are, you might want to just set AppendDataBoundItems to false on the second list so that it doesn't matter that it's re-bound.
Try wrapping your selection in:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
storeDropDown.SelectedValue = "someStore";
}
}
I've got a shell tray icon with an attached context menu. The problem I'm having is that calling ShowDialog() from a context menu Clicked handler does not result in a modal dialog.
It's easy to reproduce this with a default C# project. Simply add the following code to the Form1.cs file:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
ToolStripMenuItem contextMenuShowMsg = new System.Windows.Forms.ToolStripMenuItem();
contextMenuShowMsg.Name = "contextMenuShowMsg";
contextMenuShowMsg.Text = "Show MessageBox...";
contextMenuShowMsg.Click += new System.EventHandler(this.contextMenuShowMsg_Click);
ContextMenuStrip contextMenuStrip = new System.Windows.Forms.ContextMenuStrip(this.components);
contextMenuStrip.Items.Add(contextMenuShowMsg);
NotifyIcon notifyIcon = new NotifyIcon();
notifyIcon.Text = "DlgTest";
notifyIcon.Icon = SystemIcons.Application;
notifyIcon.Visible = true;
notifyIcon.ContextMenuStrip = contextMenuStrip;
}
private void contextMenuShowMsg_Click(object sender, EventArgs e)
{
MessageBox.Show(this, "Test MessageBox");
}
If you build and run this, you will be able to get two message boxes on the screen by simply choosing the context menu item twice. Shouldn't this be modal? Replacing this with a call to ShowDialog() for another form results in the same non-modal behavior.
My best guess is that the NotifyIcon isn't specifically tied to the Form, as it would be in a typical Windows application. But I don't see any way of doing that.
Any ideas? Thanks in advance for any help!
I would suggest doing two things before you attempt to display a modal message box:
Make your icon's owner-window visible.
Give it focus.
Once you've done that, the this in the MessageBox.Show becomes a legal "modality parent".
Heck, it even makes more sense that the message box will be displayed on top of whatever program generated it, right? That way, the user has some context for what the message box is about!
You will need to keep track of activations of your system tray menu, and disable it when a dialog is open.
