Postback parameter duplication after call to Render()
Hi,
Iam having a very weird problem that is happening after a DirectEvent from a combobox in which calls TableGrid.Render()
The following happens:
Every time the Render() function is called a new DatabaseManagerModuleTableColumnsGrid_SM and DatabaseManagerModuleTableGrid_SM entry is added to the headers, any idea why?
DatabaseManagerModule.cs
