Hide Headers declaratively in detail tables?

Good day.. busy day on the forums for me. sadly.
Mastertable view has two DetailTables within it. They are nested as :
<MasterTableView>
    <DetailTable>
    </DetailTable>
    <DetailTable>
    </DetailTable>
</MasterTableView>

I need to evaluate whether or not there are records within the detailtable and if the detailtable is emplty, then hide the header. Problem is that I can't see where or how to count the records when the mastertable is expanded. I have tried to run RemoveHeaders() within the radgrid pre_render, DetailTableDataBound, ItemDatabound and ItemDataBinding.. but none are working as expected. thank you for any assistance you can provide.

code is as follows

    
            Protected Sub RadGrid1_DetailTableDataBind(ByVal source As Object, ByVal e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles RadGrid1.DetailTableDataBind  
        
                    removeheaders()  
        
                End Sub  
        
            Sub removeheaders()  
        
                    ' RadGrid1.Controls.Add(New LiteralControl(RadGrid1.MasterTableView.DetailTables.Count)) //This should return mastertable recordcount  
        
                    ' RadGrid1.Controls.Add(New LiteralControl(RadGrid1.MasterTableView.DetailTables(0).Items.Count))//This should return Detail 1 recordcount  
        
                    ' RadGrid1.Controls.Add(New LiteralControl(RadGrid1.MasterTableView.DetailTables(1).Items.Count))//This should return Detail 2 recordcount  
        
                    For i As Integer = 0 To RadGrid1.MasterTableView.DetailTables.Count - 1 ' Count the Detail table within MasterTable  
        
                        If RadGrid1.MasterTableView.DetailTables(i).Items.Count <= 0 Then  
        
                            RadGrid1.MasterTableView.DetailTables(i).ShowHeader = False 
        
                        Else  
        
                            RadGrid1.MasterTableView.DetailTables(i).ShowHeader = True 
        
                        End If  
        
                    Next  

            End Sub

Hi,

I have a RadDock that has a user control inside it. The control is embedded in a RadAjaxPanel. The rough structure is something like this

<telerik:RadDock id="xxxxx"..........................>
<ContentTemplate>
     <telerik:RadAjaxPanel id="xxxx"......................>
         <Usercontrol:Mycontrol   Id="xxx" runat="server" onButtonClick="Button_Click"............ />
     </telerik:RadAjaxPanel>
</contentTemplate>
</telerik:RadDock>

Whenver the Button_Click event is fired, I want the RadDock title to be updated.
Is there a way we could achieve this ?

ItemDataBound event in Dynamic Treeview

Hi,
Based on certain criteria Im binding items in RadMenu, in which am supposed to populate the RadTreeView inside one of the RadMenuItem (named "Tools") dynamically. Ive done this using ItemDataBound of RadMenu. (below is the Code) :

protected void TopMenu_ItemDataBound(object sender, RadMenuEventArgs e)

{

if (!string.IsNullOrEmpty(e.Item.NavigateUrl))

e.Item.Attributes["onclick"] = "return Redirect(this.href);";

if (e.Item.Text.ToLower() == "Tools".ToLower())

{

RadMenuItem radTools = new RadMenuItem();

RadTreeView radToolTreeView = new RadTreeView();

radToolTreeView.DataTextField = "Text";

radToolTreeView.DataFieldID = "MenuID";

radToolTreeView.DataFieldParentID = "ParentID";

radToolTreeView.DataNavigateUrlField = "Url";

radToolTreeView.LoadingMessage = "Loading...";

radToolTreeView.Skin = "Web20";

radToolTreeView.CssClass = "MenuTreeView";

radToolTreeView.DataSource = BindToolMenu1();

radToolTreeView.BackColor = System.Drawing.Color.Aqua;

radToolTreeView.DataBind();

radToolTreeView.ExpandAllNodes();

radTools.Controls.Add(radToolTreeView);

e.Item.Items.Add(radTools);

}

from the above code, I am able to set the attributes for RadMenuItem

e.Item.Attributes["onclick"] = "return Redirect(this.href);";

I need to set the same attribute on clicking on TreeViewNode. Please tell me how to do this?

Thanks in advance
KSP
