Hello,

Here I need to find DataFieldId from RadTreeView through javascript. My scenario as under:

RadTreeView Fillup as:

RadTreeView1.DataTextField = "ModuleName";
RadTreeView1.DataFieldID = "ModuleID";
RadTreeView1.DataValueField = "URL";
RadTreeView1.DataFieldParentID = "ParentModuleID";
RadTreeView1.DataSource = lstmenu;
RadTreeView1.DataBind();

As above I need DataTextField to display text of my modules, DataValueFields which i am using in JS to pass local url in it. In DatafieldId I am storing "ModuleId". But in javascript I can not find DataFieldId which I need to user on click of RadTreeNode.

JS as like:

function onNodeClicking(sender, args) {
    if (args.get_node().get_value() != null) {
        //window.open(args.get_node().get_value(), args.get_node().get_text(), 'resizable=yes')
    }
}

in above js I need to find DataFieldId also. Please assit me how to do this.

Thanks & Regards,

I also attached excel file for reference ... in grid i have datetime as 5/4/2011  1:18:03 PM but in exported excel file it is in 5/4/2011  13:18:03  when i click on this cell it shows me in 12 hr format but my requirement is it will be in 5/4/2011  1:18:03 PM only .... i can customize my column excel but thats not feasable beacuse every time i export i need to customize it ... Kindly look into the issue ASAP .

I receive a "Invalid group by expression: Group By clause missing" when grouping a GridTemplateColumn. However, if I set that same column as a GridBoundColumn, grouping works correctly. Also, if I set the GridTemplateColumn to be grouped by default the GroupByExpressions collection, it is grouped properly, but then if I remove the grouping and drag the column to be grouped again, it fails with the same error.

If I remove the GroupByExpression from the GridTemplateColumn definition and try to group by dragging, I get a "Telerik.Web.UI.GridGroupByException: Expression cannot be null or empty" error.

GridBoundColumn definition that works:

<

 

 

telerik:GridBoundColumn

 

 

 

UniqueName="School1"

 

 

 

SortExpression="School"

 

 

 

DataField="School"

 

 

 

HeaderText="School"

 

 

 

AllowFiltering="true"

 

 

 

Groupable="true"

 

 

 

HeaderStyle-Width="75"

 

 

 

ItemStyle-Width="75"

 

 

 

FooterStyle-Width="75"/>

 

GridTemplateColumn defination that fails (with GroupByExpression="School" I get "Invalid group by expression: Group By clause missing" and without it I get "Telerik.Web.UI.GridGroupByException: Expression cannot be null or empty":

<

 

 

telerik:GridTemplateColumn

 

 

 

UniqueName="School2"

 

 

 

SortExpression="School"

 

 

 

DataField="School"

 

 

 

HeaderText="School"

 

 

 

AllowFiltering="true"

 

 

 

Groupable="true"

 

 

 

HeaderStyle-Width="75"

 

 

 

ItemStyle-Width="75"

 

 

 

FooterStyle-Width="75">

 

 

 

<ItemTemplate>

 

<%

 

# Eval("School") %>

 

 

 

</ItemTemplate>
</telerik:GridTemplateColumn>

 

I have a RadGrid with serveral columns.  The columns that are not GridBoundColumns group fine.  However, my GridTemplateColumns are throwing errors when a user tries to group by them.

I am using Telerick Web.UI version 2008.3.1105.35

Sample code which is breaking

I have two rows to test and neither column has empty data but it still throws this alert.

We  are trying to upload a file from a RadEditPopup which is opened from a Radgrid control. However, we could not get the file name from the RadUpload control. The RadUpload control returns a null value for the file name (it works properly when the control sits on a stand-alone page as in your web-demo for this control).  For your reference, I have  pasted code below which demonstrates the problem we are experiencing. Your prompt attention to this issue would be greatly appreciated. Thank you for your time, and we look forward to hearing from Telerik Support very soon.
