RadGrid with dynamically created template column containing Multiselect combobox

Hi,
I am using a rad grid. I have added custom template columns dynamically. On template column i am having a custom multiselect combobox (RadComboBox with CheckBox and Label inside ItemTemplate).

How can i access the combo selected value on post back due to save buton click.
if possible send me sample solution with dynamically created multiselect ComboBox.

I am using following code snnipet for custom combobox:

public class CustomDDLItemTemplate : ITemplate
{

ListItemType templateType;
string ColName = "AppName";

    /// <summary>
    /// Create the template
    /// </summary>
    /// <param name="container"></param>
    public void InstantiateIn(Control container)
    {
        CheckBox checkBox = new CheckBox();
        Label lblDisplayText = new Label();

        checkBox.ID = "checkBox";
        checkBox.Attributes.Add("onclick", "onCheckBoxClick(this,'"+ container.ClientID +"');");

        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.
container.Controls.Add(NewControl);

        NewControl.Controls.Add(checkBox);
        NewControl.Controls.Add(lblDisplayText);
        break;
    }

    public void Label_DataBind(Object sender, EventArgs e)
    {
        Label lbl = (Label)sender;
        RadComboBoxItem radCombo = (RadComboBoxItem)lbl.NamingContainer;
        lbl.Text = DataBinder.Eval(radCombo.DataItem, ColName).ToString();
    }

}

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

Telerik issues in single IP cluster server

Hello

We are are replacing the control library used in one of our legacy applications for asp .net ajax and while promoting the changes to our QA environment we are getting the following error:

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.

RadGrid Update Command Not Firing

I've seen numerous other threads in which the update command is not working, but none of them I have found are exactly like my situation. I am programmatically building multiple RadGrids on a single page, each of which is contained in its own RadPanel, and all of the panels are inside a RadAjaxPanel. I am using a custom implementation of the IBindableTemplate for the RadGrid's EditForm. Everything is working fine when I click the delete button (Delete command is fired and the record is deleted).

When I click the "Add New Record" button, the template appears just fine, I can enter information, press the insert button, and the record is inserted and can be seen in the grid. However, when I click on the edit button, the grid goes into edit mode just fine, all values are populated in the template just as they should be and an "Edit" item command is fired.

However, once inside this edit mode, no events fire. If I click on the update button, no update command is fired, and the same is true for the cancel button. I don't understand why the edit mode fails to work but the insert mode works just fine. Any help would be appreciated!
