Problem with Gridview

Question

Hi all,

I want to develop a asp.net webapplication, but I have a big problem with the gridview and the data editing.

The data is in the gridview.
But if i press the edit-button there comes:

[HttpException (0x80004005): The GridView GridView1 RowEditing triggered the event, which was not treated.]
 System.Web.UI.WebControls.GridView.OnRowEditing(GridViewEditEventArgs e) +1321226 System.Web.UI.WebControls.GridView.HandleEdit(Int32 rowIndex) +43 System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +611 System.Web.UI.WebControls.GridView.RaisePostBackEvent(String eventArgument) +207 System.Web.UI.WebControls.GridView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

But in my code i have the method.

I tried this also with vb, there it works except the update method :/. But not with c# :(((

I don't know what to do :((
