enumeration operation may not execute

[Lee Malo]

I have the following code on item command

 

protected void RadGrid_ItemCommand(object source, GridCommandEventArgs e)

 

{

 

if (e.CommandName == RadGrid.InitInsertCommandName)

 

{

 

// cancel the default operation

 

e.Canceled =

true;

 

 

//Prepare an IDictionary with the predefined values

 

System.Collections.Specialized.

ListDictionary newValues = new System.Collections.Specialized.ListDictionary();

 

 

//set default checked state for the checkbox inside the EditItemTemplate

 

newValues[

"SET0"] = false;

 

 

//Insert the item and rebind

 

e.Item.OwnerTableView.InsertItem(newValues);

}

}

This sets the dafault value of a checkbox to false on an insert.
When there is data in the table already this works but if the table is empty I get
"Sys.WebForms.PageRequestManagerServerErrorException: Collection was modified; enumeration operation may not execute."
any suggestions?

Hello Lee,

I am afraid that we are not aware of such error. Can you please provide more information like how you are binding RadGrid etc. Thus we'll be able to assist you further.
