OnClientSelectedIndexChanged fires twice

Hi guys,

I am trying to do some logic when a new value is selected from the combobox.

I hooked up a callback function to the OnClientSelectedIndexChanged event. When I select a new element the event fires and when I click anywhere else ( the Combobox will lose focus) the event will fire again.

How can I overcome this?

[Solved] Too many Telerik controls causes style loss in IE

I'm having this problem:

http://www.technullogy.net/index.php/2010/03/05/internet-explorer-limits-css-and-script-resources-to-30/

To duplicate it, try adding one of each Telerik control to a page, then open the page in IE and see if all them appear correctly. I have a page that has several different Telerik controls (RadAjax, RadTooltip, RadTabStrip, RadDate and Time Pickers, RadEditor, etc). If I count all of the WebResource.axd references that IE 8 is making, it's over 30. If I remove a couple Telerik controls, then the remaining controls get their style back.

They all appear perfect in Firefox 3.6.8, Chrome and Safari, so I know it's an IE 8 issue. Is Telerik aware of this? Is there any way around this?

Self-referencing Hierarchy and DetailTable count

Hi,

I have a self-referencing hierachical radGrid. I am loading data thru the NeedDataSource event handler. When I have 3 levels of hierarchy, the gridInstance.MasterTableView.DetailTables.count shows 1 , MasterTableViewDetailTables[0].DetaitTables.count is 1, so far so good. Now when I look at the last (the lowest level) GridTableView, its DetaitTables.Count is also 1 whereas this GridTableView does not have any children. What am I missing? Is the DetailTables count always 1 when using Sel-Referencing Hierarcy? even for the GridTableView which has no chidren? Using RadControls for Ajax 2010_1_519 and Framework 3.5.

Thanks in advance for your help.

NHibernate.Linq, IQueryable, and Viewmodels

I have a scenario where I use NH.Linq to access data, returning and IQuerable which I then bind to the Telerik Grid and it handles paging and sorting and filtering and all of that. A situation arose where I'm going to need to integrate another data type in to the grid and the solution there would be a common view model between the two grid types.

What I'd like to do is convert my entities to a view model prior to it getting to the aspx page -- so it would only pull down the records that I need by virtue of the DataSource/IQueryable, but then I could shape the data as needed by converting it to a view model prior to populating the grid in the aspx page.

Is there anything I can hook in to so as to accomplish this?

Thanks
Don

Using WebUserControl as nested view template

Hi
I am creating my grid (with nested view) fully in code-behind & it all works fine when I set 'NestedViewTemplate' to my custom template class. What I was wondering is whether I could use an ascx instead of a ITemplate class?

Out of interest I took a long shot and tried this but it doesn't work:

public class ChildTable :ITemplate

{

public void InstantiateIn(System.Web.UI.Control container)

{

Table tb = new Table();

TableRow tr = new TableRow();

TableCell td = new TableCell();

TextBox txt = new TextBox();

MyUserControl uc = new MyUserControl();

td.Controls.Add(uc);

tr.Cells.Add(td);

tb.Rows.Add(tr);

container.Controls.Add(tb);

}
