Hello
I have a radgrid in my form.
I also have a radiobutton that control if I want to see the radgrid or not
My radgrid is in the TrMultiple <tr>
On the page load I do
 And my RadioButton looks like this:
and my radgrid:

When I click on the radio button to put it visible (value = 1) then I see a little blue line as my radgrid seems to be empty. However, If in my page load I put the radiobutton value to 1, I see my radgrid as It should be..And after that, if I select the value 0 of my radio button and reselect the value 1 to make appear my grid, it shows my grid correctly.
It seems to happens only when I put the radgrid visible to false on page load...
how can i fix it?
Thank you

Hi,

I am using pageview.contentUrl which creates an Iframe with the src attribute. How can I set an iframe ID from the codebehind.

Thanks

Hello,

  I am trying to access the controls( textbox and dropdown) in template columns in the javascript. The way i am doing is,,,
 var lat = '<%=txtComments.ClientID %>';
                   var lon  = '<%= ddlReason.ClientID %>';

But i am getting a error that those controls are not declared...

I am calling that javascript function like thiss

 <telerik:GridTemplateColumn HeaderText="Reason" UniqueName="Reason" Visible = "false">
        <EditItemTemplate>
          <asp:DropDownList ID="ddlReason" runat="server" ToolTip="Reason"   OnSelectedIndexChanged="NoShowReason(); return    false;" >
 </asp:DropDownList>
</EditItemTemplate>
   </telerik:GridTemplateColumn>

How do i do this????

Appreciate the help
Thanks

Would it be possible to implement <EditFormTemplate> and <InsertFormTemplate> in RadGrid's <EditFormSettings>? Currently I have to have code behind (often done with <% %> tags but still server side code) to set the visibility, text, etc of controls on the <FormTemplate>, it would be so much better if the layout for both versions could be done with no server-side code. Other edit controls (eg RadListView) have separate templates for edit & insert and it works well.

Thanks

PS: I tried to add a feature request in PITS but couldn't seem to get it to work.

Hi,
I have a collection of about 500 classes I need to display in Telerik RadGrid.
The classes have a parent-child relationships data.
I have configured the grid like in examples for self-reference hierarchy, but when I run the application I get the following error:
Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

The Parent property: GrpParentDeptId
Child property: GrpDeptId

I don't know why is this happening. I have only 500 rows!!!
I also tried setting the 

<system.web.extensions>  
   <scripting>  
       <webServices>  
          <jsonSerialization maxJsonLength="2147483644" />
       </webServices>  
   </scripting>  
</system.web.extensions>

but with no luck.
I am sending you the attachment with the views, code-behind, and the data xml I am pooling the data from.

Please help.

Hi,

I have a TreeView where all the nodes expand mode is set to ServerSideCallback. When new nodes are added their expand mode is also set to ServerSideCallback.

In my situation I need to expand the selected node based on the result of a partial postback.

On the server side I have a handler for the NodeExpand event.

protected void rtvMain_NodeExpand(object sender, RadTreeNodeEventArgs e)
{
    // Logic/Breakpoint here

}

And I have a javascript function that looks like this:

 function ExpandSelectedNode() {
                 var tree = $find("<%= rtvMain.ClientID %>");

                 if (tree.get_selectedNode() != null) {

                     var selectedNode = tree.get_selectedNode();
                     selectedNode.expand();
                 }
             }


After the ajax/partial postback I call the javascript function by registering a startup script. I use ScriptManager.RegisterStartupScript and call my javascript function "ExpandSelectedNode()"

In the treeview I see the default loading animation appear on the selected node, which would indicated it is performing an asynchronous operation. The problem is that the server side handler "rtvMain_NodeExpand()" never gets called.


However, when I click the [+] next to the treeview item the postback is fired and it calls "rtvMain_NodeExpand()" as it should. This tells me that my treeview and its nodes are configured properly. So I have to assume there is a bug in the RadTreeNode.expand() client side method that is preventing it from firing the server side callback.

Hi, 
 I encounter a problem that i use template edit form of grid, but in the edit form, the textbox value never be updated, always keep the old value. Can you help me find why this happen?  Please see the bold fonts.

i have a radGrid with ColumnFilters that allows paging as well. we've been doing exports to excel from an external button that's simply been running the same thing as the need datasource. however, the only thing i cannot figure out how to do is "capture" any column filtering. it seems like i have to use an external radFilter apart from the grid to do this. is there a way to get what someone has filtered to on the column? most of our grids use the external radFilter & this export works just fine, i can tap into those filters. just can't figure out if it's possible to do the same with the column filters. thanks for any help on this.

I have a radgrid using master detail hierarchy and I want to be able to disable the edit and insert commands depending on the user. Where is the best place/event to disable these commands? I am able to prevent the Insert command from being visible but can't find where to hide the Edit.
