e.Node.Selected

This works great except e.Node.Selected = False
I try disable that you can click (select) on node 1 and 2, but it may not function?
Help me :-)

Protected Sub RadTreeView1_NodeDataBound(ByVal sender As Object, ByVal e As RadTreeNodeEventArgs)

e.Node.ToolTip = (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() & " + " & (TryCast(e.Node.DataItem, DataRowView))("ParentNodeId").ToString()

e.Node.ImageUrl = "../images/caTree/" & (TryCast(e.Node.DataItem, DataRowView))("ImageUrl").ToString()

e.Node.NavigateUrl = "../admin_dbpage.aspx?id=" & (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() & "&db=ledare" & "&url=ledare/"

e.Node.Target = "main"

If (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() = 1 Or (TryCast(e.Node.DataItem, DataRowView))("NodeId").ToString() = 2 Then

e.Node.AllowDrag = False

e.Node.Selected = False

End If

End Sub

pageLoad() doesn't run in Chrome

Hi there

I am using the method pageLoad(), which as you know is a function that pages with an ASP.NET ScriptManager will automatically execute after ASP.NET AJAX's client-side library initializes and then again after every UpdatePanel refresh.

I found that Chrome doesn't consistently/reliably fires pageLoad() when navigating to my webpage using the site's navigation. The method gets executed reliably when a postback happen though but not when visiting the page (could it be because it's getting cached?). This (when not executed) causes Telerik controls freeze.

IE & Firefox are fine (consistently fires pageLoad()).

I am using telerik:RadScriptManager as my ScriptManager.

Any assistance with this will be much appreciated.

Note: I am using the below in Page_Init() so that the page is not cached but still have the problem with Chrome:
. Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
. Response.Cache.SetNoStore();

Regards,
Muzafar

Update calling ItemCommand with e.Canceled = true

I have a Radgrid with a template edit form, which has update & cancel buttons. All functions work fine, except with some data records.

With those records, when I click the update button, the ItemCommand event is called with RadGrid.UpdateCommandName, but e.Canceled is already set to true, so the record is never updated. I have tried removing all validation, but that makes no difference. If I capture the the RadGrid.UpdateCommandName event and set e.Canceled to false, the record is updated no problem.

So I'd really like to know what might be causing the RadGrid to set Canceled = true?

Thanks for any info.

[Solved] No smart tag or properties for RadChart

I was working on a radchart and it would not display in my page. I used the add httphandler to web.config link on the smart tag to create a web.config for my plugin, so I could see if I needed to add to the sites web.config. After adding the lines to the web.config the chart appeared and I deleted my plugins web.config. Now the chart smart tag and properties are gone. I am assuming that removing the web.config caused them to disappear. I was wondering if there is anything I can do to bring back the properties and smart tag.

How to make Radgrid edit autoform save TextWithLiteral?

Hi

We have a requirement where we want to save phone numbers into the DB along with the formatting of (###) ###-#### .

These numbers are entered on a RadGrid, where I use a GridMaskedColumn with a Mask of (###) ###-#### so that the auto-edit form displays the mask for the user when he is entering the number.
But once the user has entered the number and presses the insert link, it the numbers w/o the formatting into the DB field.

Question: How do I set up my GridMaskedColumn (or any other type of GridColumn) so that the generated edit form will have the text field with the Mask and also insert / update the data along with the mask?

FWIW - I found that the MaskedTextBox control has a TextWithLiterals property which returns the string with the formatting, but I'm not sure how to force the edit form to save this TextWithLiterals instead of just the Text.

Any guidance will be very much appreciated.

Thanks

client side iteration through ListBox items

Hi,

I have the following ListBox and I want to loop through the values entered into the text box and enable a button if they pass validation.

<telerik:RadListBox ID="rlbDocuments" runat="server" EnableDragAndDrop="True" AllowReorder="True" Height="400px" Width="480px" ButtonSettings-ShowReorder="False">

<HeaderTemplate>

<div style="width: 88px; text-align: center; clear: none; float: left;">Page Count</div>

<div style="width: 160px; clear: none; float: left;">Document Name</div>

<div style="width: 160px; clear: none; float: left;">Document Type</div>

</HeaderTemplate>

<ItemTemplate>

<div style="width: 100%; height: 28px;">

<input id="txtPageCount" type="text" style="width: 40px; margin: 0 18px; clear: none; float: left;" onchange="txtPageCount_TextChanged()" />

<div style="width: 160px; clear: none; float: left;"><%# Eval("documentName") %></div>

<div style="width: 160px; clear: none; float: left;"><%# Eval("documentType") %></div>

</div>

</ItemTemplate>

</telerik:RadListBox>

I've gone through your examples using and tried some things like below, but I have not found the magic formula for finding the text box in each row and getting its value.

var list = $find("<%= rlbDocuments.ClientID %>");

var items = list.get_items();

I'm finding the list and getting its items, but cannot find the controls inside each row. Can you please give me some guidance here?

Thanks,
John
