Dear all.

With thanks to Azim for helping me previously I near have a near full functioning form.

I simply need to edit each row independantly. However upon applying the Edit, Update Cancel I get the following.

I suspect this is because I am using the GUI and this will require some code per coloumn?

Error [HttpException (0x80004005): The GridView 'GridView1' fired event RowEditing which wasn't handled.] System.Web.UI.WebControls.GridView.OnRowEditing(GridViewEditEventArgs e) +1610245 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) +205 System.Web.UI.WebControls.GridView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +9671830 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1724

Thank you for looking.

Maggi, You'll first need to fire the RowEdit Event in order to grap the Index of the Row under Edit:

 Private Sub gvMyGridView_RowEditing(sender As Object, e As GridViewEditEventArgs) Handles gvMyGridView.RowEditing
        gvMyGridView.EditIndex = e.NewEditIndex 'That will the index of the Row under Edit
 End Sub

Then pass the EditIndex into the GridView PreRender Event where you'll apply your intended logic:

Private Sub gvMyGridView_PreRender(sender As Object, e As EventArgs) Handles gvMyGridView.PreRender
	'Manadatory if statement in order recognize whether GridView is under Edit or not
        If gvMyGridView.EditIndex <> -1 Then 'Means it's under Edit Mode

            'You Logic Here

        End If
End Sub

Good Luck
