Hi there,

I am facing an error when trying to add a new row in the webdatagrid. Upon pressing enter and selecting the values I want in the dropdownproviders. This error is thrown - An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1743

I created the editor providers and assigned them to  the webdatagrid at runtime. They are only assigned if it's not a postback. I did specify the value and textfield as well.

 protected void Page_Load(object sender, EventArgs e)
 { 
  if (!this.IsPostBack)
  {
   this.CreateColumns();
   this.CreateEditorControls();  <-- This is where I create them and assign them to the columns.
   this.CustomiseGrid();   
  }

 }

Is this caused by me assigning my dropdownproviders at runtime or is it something to do with the Ajax request not completing ? Can I know what is causing the problem and how do I fix it please ? Thank you.
