        lblDisplayText.ID = "label";
        lblDisplayText.DataBinding += new EventHandler(this.Label_DataBind);

// Create a new HtmlGenericControl.
HtmlGenericControl NewControl = new HtmlGenericControl("div");

// Set the properties of the new HtmlGenericControl control.
NewControl.Attributes.Add("onclick", "StopPropagation(event);");

// Add the new HtmlGenericControl to the Controls collection of the PlaceHolder control.

Only want ONE tooltip!

I'm using a RadToolTipManager and setting the body of my Tooltip in the .Text property (serverside).

I then add lots of tables cells to the TargetControls collection.

All works fine.

However, I want to call some javascript functions triggered by jQuery event listeners attached to elements with a known id within my Tooltip markup - e.g. a button.

This is only working for the Tooltip shown on the first table cell I hover over.

Looking at the source code, I see that a separate ToolTip is generated for EVERY cell I hover over.

This means the same id's appear multiple times - not only is this bad HTML but my triggers only work on the first one.

Is there a way to force the RadToolTipManager to only ever create one Tooltip and show that every time?

Thanks

The rest of the application is working fine, just the pages using telerik controls are getting the error and even then everything works fine if the application is executed from individual members of the cluster.

Any ideas of what is going on here?

Regards,
Alejandro

RadPanelBar Click event is not firing

Hello,

I am using Telerik PanelBar. I am using the version of 2010.3.1317.20. I cant upgrade to the latest version as the framework I am using .Net 2.0.

I have added the PanelBar in the MasterPage, When i Click on any of the item in the panel bar, the Click event is not firing.

The panelbar is populated at runtime. also the NavigateUri is set at runtime.

<telerik:RadPanelBar runat="server" ID="RadPanelNavBar" Visible="false" ExpandMode="MultipleExpandedItems"

OnItemClick="RadPanelNavBar_ItemClick" EnableViewState="true">

</telerik:RadPanelBar>

the below code is how i am adding the RadPanelItems

For Each mnuChildRow As DataRow In dtFilterData.Rows

Dim menuAdminChild As New RadPanelItem()

menuAdminChild.Text = mnuChildRow.Item(Field.DisplayName).ToString()

menuAdminChild.NavigateUrl = "../" + mnuChildRow.Item(Field.ResourceName).ToString()

menuMFGHeader.Items.Add(menuAdminChild)

Next

The click event is below

Protected Sub RadPanelNavBar_ItemClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadPanelBarEventArgs) Handles RadPanelNavBar.ItemClick

If e.Item.Items.Count > 0 Then

If e.Item.Expanded = False Then

'Label1.Text = "Collapsed panel item - " + e.Item.Text

Else

'Label1.Text = "Expanded panel item - " + e.Item.Text

End If

Else

'Label1.Text = "Clicked panel item - " + e.Item.Text

End If

End Sub

What finally i require is to have the RadPanelItem as selected on which the user last clicked. rest all remains un selected.

Using filter on LINQ grid is slow

I'm stumped on this performance issue. When paging a RadGrid I get instantaneous results. However, when I filter any of the columns, the query takes around 10 seconds to complete and any paging applied after the filter remains just as slow. If I remove the filter the performance is just fine.

Production is a SharePoint 2010 Server which is hosted in-house with a small number of users. I am using a RadGrid control, version 2009.3..1314.35 that queries a table containing 30,000 records. I am using LINQ to SQL for the back-end. I have used IE and Firefox in production. On my development machine there are no performance issues.

Below is my code. Any help would be appreciated.

ASPX:
