Error when selecting a different page size in radgrid

I am using the lates telerik DLL Q2 2011 for .Net 3.5 and am receiving the error below when testing a radgrid with paging enabled. This error is thrown when I manually change the page size from the default (20) to another page size. Are there any known issues with this function or is there a possible bug in my code?

copy functionality with radgrid using radwindow

Hi,

I have the below itemcommand event of radgrid for copying a record based on ID.

if (e.CommandName == "Copy")

{

SHTemplateUI copyTemplate = new SHTemplateUI();

copyTemplate.CopyTemplateByIdUI(Convert.ToInt32(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["StudentHistoryTemplateID"]));

this.LoadTemplateList();

}

This copies the record with the same name.

Now i want to make some changes.when i click on copy it should popup a radwindow and ask for the new file name.Once i enter the file name it should check whether the file name already exists.If not copy record with the new file name.

Can anybody help me please?

Thanks.

RadGrid - A grid within a grid?

Is it possible to have a radgrid inside one of the cells of a regular radgrid?

Kind of like this.

Name Email Phone [new grid here]





Name      Email        Phone       [new grid here]





Name      Email        Phone       [new grid here]





Name      Email        Phone       [new grid here]





Name      Email        Phone       [new grid here]

I don't want to click anything to make the child grid appear below. I want it to be in a certain cell on each row always visible. Make sense?

Is this possible? Is there a demo technique of this anywhere?
