Hi,
I have a tree view in the following shape with the checkbox support...

Text: Paret-Node-1    Value:1
        Text: Child-Node-1       Value:1
        Text: Child-Node-2       Value:2
        Text: Child-Node-3       Value:3
Text: Paret-Node-2    Value:2
        Text: Child-Node-4       Value:4
        Text: Child-Node-5       Value:5
        Text: Child-Node-6       Value:6

How can I get the "values" of Parent node and child nodes.

Regards,

TreeView

Assembly Error

Hello there,

I've currently installed the trial version of the telerik ultimate collection and I want to add a RadMenu to my website. I've found some examples on the web and I tried to build my code.

But I get the error;

'Telerik.Web.UI, Version=2010.1.519.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4' File or assembly name or one of its dependencies not found.

I have the Telerik.Web.UI in my bin folder and it references to Bin35 folder in program files, which means the dll is for dotNET 3.5. The another issue is my DLL version is not 2010.1.519.20. My DLL's version is 2010.2.713.35 and I registered it into GAC util. I'm using W7 Ultimate and VS2008 SP1.

What do I need to do now?
Thanks.

[Solved] ListView binding issue

Hi guys!
We've been using Telerik.Web.UI v.2010.1.309.35 in our project, and recently have switched to v.2010.1.519.35 . Since that I've discovered that ListView doesn't seem to process <%%> tags correctly during binding. For instance, here's the EditItemTemplate that I have:

<EditItemTemplate>

<tr>

<td style="vertical-align:top">

<rlt:TextBox ID="txtDurationMonth" runat="server"

ValueType="Integer"

Width="50px"

Text='<%#Eval("DurationMonth") %>'

></rlt:TextBox>

<asp:RangeValidator runat="server"

ControlToValidate="txtDurationMonth"

ErrorMessage="Integer value required"

MinimumValue="0"

MaximumValue="<%#int.MaxValue %>"

Type="Integer"

SetFocusOnError="true">

</asp:RangeValidator>

</td>

<td style="vertical-align:top">

<rlt:LinkButton ID="lbSave" runat="server"

CommandName="<%#RadListView.UpdateCommandName%>" CommandArgument='<%#Eval("Id") %>'>Save</rlt:LinkButton>

</td>

</tr>

</EditItemTemplate>

When I switch into Edit mode, I started getting an exception that it cannot parse '' (empty string) for MaximumValue of rangevalidator. I removed that validator at all and it switched fine, but CommandName of lbSave was always empty. Also, ListView has DataKeyNames="Id" However, if I try to get an ID in ListView ItemCommand handler like this:

((

RadListViewDataItem)e.ListViewItem).GetDataKeyValue("Id")

I get "index was out of range" exception. So I had to switch back to v.2010.1.309.35. And now it works as it should, but that version has an issue with RadEditor, which is being stretched in some occasions.
So, is it some bug or do I miss something? Thanx in advance!

Masterpage & Ajaxloadingpanel

I've got a Masterpage with an Ajaxmanager & loading panel on & 2 content panels. Content1 is a menu and Content2 is the actual aspx pages for the application where 100% of the application is loaded. On the screens there are save & cancel buttons with code behind procedures. I want to be able to show the loading panel when clicking save or cancel or even when an aspx page is loading.

Is this achievable and how?

Group Headers not appearing while exporting to excel

Hi Telerik Team,

The issue is my group headers are not coming while exporting since I am writing the following code:
if (e.Item is GridGroupHeaderItem)
{
(e.Item as GridGroupHeaderItem).DataCell.Visible = false;
e.Item.PreRender += new EventHandler(Item_PreRender);
}
which is hiding the GroupHeaders DataCell since I need to customize the header as demonstrated in the following link
http://www.telerik.com/help/aspnet-ajax/aligning_items_in_groupheader2.html

Now,Please let me know with (e.Item as GridGroupHeaderItem).DataCell.Visible = false;
and creating my own Table cells for the group header how can I bring the group header while exporting to excel?

I think export to excel takes group headers from Datacell only it does not identify anything else.Since I am adding table cells manually in the header it is not getting those.Please let me know how to resolve this issue?
Regards,
Shubh

Input controls in Grid not setting Dirty flag

Using jQuery to track changes on a form automatically sets the dirty flag for all controls at the form level, but controls (TextBox, DropDownList) inside a Grid edit row are not captured. We are using the $(":input").change() method to capture changes in input controls. Is there any automated way to capture the controls inside the Grid edit row?
