Events doesn't trigger in GridTemplateColumn filled with customized control

Problem when trying to call a control method (code behind) inside GridTemplateColumn.

I created a class that implements ITemplate. Here I have a control that is instantiated inside the InstantiateIn() method. In that control I register a listener for the TextChanged event e set the AutoPostBack property of the control to TRUE.

In a radgrid, I created a GridTemplateColumn and set the ItemTemplate and the EditItemTemplate properties of the grid.

The grid shows properly, but when I change the text of the GridTemplateColumn control, a ajax call is done (the OnInit method of the page at server-side is called) but the TextChanged event at server-side isn't called.

RadGrid Client MasterTableView SelectedItems

All

I have been looking at and trying all of the posts showing client-side scripting to get RadGrid selecteditems collection but cannot seem to get there. My code always seems to fail after getting the grid object.

Below is what i have tried. Anyone see where I am going wrong?

//THIS
var grid = window["<%=gvList.ClientID%>"];
// OR THIS
var grid = $find("<%=gvList.ClientID%>");
if (grid)
{
    // ALWAYS SUCCEEDS
    alert("found grid"); }
    // FAILS HERE, error object does not support this method or property
    var masterTable = grid.get_masterTableView();
    if (masterTable)
    {
        alert("found masterTable");
        var gridSelectedItems = masterTable.get_selectedItems();
    }
}

RadGrid Tooltip and Virtual Scrolling

The tooltip gets stuck on the first page of the grid. When I scroll it doesn't update the tooltip. How can I get the tooltip to display the correct information?

I have the following:

Protected Sub RadToolTipManager1_AjaxUpdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.ToolTipUpdateEventArgs)
        Me.UpdateToolTip(e.Value, e.UpdatePanel)
    End Sub

    Sub UpdateToolTip(ByVal elementID As String, ByVal panel As UpdatePanel)
        Dim ctrl As Control = Page.LoadControl("~\UserControls\StaffProfile.ascx")
        panel.ContentTemplateContainer.Controls.Add(ctrl)
        Dim details As StaffProfile = DirectCast(ctrl, StaffProfile)
        details.UserID = CType(elementID, Integer)
    End Sub

Protected Sub StaffGrid_PageIndexChanged(ByVal source As Object, ByVal e As Telerik.Web.UI.GridPageChangedEventArgs) Handles StaffGrid.PageIndexChanged
        RadToolTipManager1.TargetControls.Clear()
    End Sub

set value of raddatepicker using javascript

I posted this earlier today, received a response from telerik and responded back. Now I can't find the thread so here goes again. First of all I'm desperate as I've spent two days trying to solve this. I just want to set the value of a RadDatePicker field to blank or null using javascript when a user clicks a corresponding asp CheckBox.

For ASP controls the following works:

document.getElementById(

'txtInsName').value = '';

In the reply I received earlier, I was told to include a "Register..." statement and then code such as rdDatePicker.clear() would work.

I'm using VB and have not used javascript before with telerik controls.

Thanks

{

GridBoundColumn detailColumn = (GridBoundColumn)item.OwnerTableView.GetColumn("overview");

detailColumn.Display =

true;
