We are so grateful for the valuable contributions experts make on a daily basis. That you are think is that column has events similar to Data Grid View Events. ' Initialize Component() ' ' Add any initialization after the Initialize Component() call. Cell Validating, Address Of data Grid View1_Cell Validating ' Last Column = 1 'End Sub 'Public Sub New() ' Initialize Component() ' data Grid View1. Fixed3D ' ' Add an event handler to validate the ' ' cell contents when focus is leaving ' Add Handler data Grid View1. Then you need to create a new class to subclass Data Grid View Text Box Column Declare the events you try to control. No you dont, lets assume that the user clicked on a cell in column 1 e.column Index would equal 1, if they clicked on a cell in column 2, then e columnindex would be 2. You can simplify it if you want to do exactly the same stuff on all three events, you dont need to use add handler, you can just add all three to the end of the handles clause However Cell Beginedit has a different eventargs to the other two so we need to find out which of these two we got first Chloes Dad: You are right But the user selected thist events Leave (Event Args) , Cell Begin Edit (Cancel Event Args), Validating (Cancel Event Args) Declaring Dim Cancel Ev = Try Cast(e, Data Grid View Cell Cancel Even Hi x77 If you use the more generic Cancel Event Args rather than the specific eventargs for the event then you will lose the column Index property which is required to decide what to do based on the column that the user is doing stuff on, which was the original question...

Displaying a Combo Box in Cell Frequently, besides displaying text in a cell you may want to display a drop-down list box to allow users to select from a list of pre-determined values. In this case, you need to add a Combo Box to the cells in the desired column. Add("Price", "Price") '---add a combobox column--- Dim combo Box Col As New Data Grid View Combo Box Column '---set the header text--- combo Box Col. This event is fired when the user tries to edit the Combo Box control: Private Sub Data Grid View1_Editing Control Showing( _ By Val sender As Object, _ By Val e As System. Editing Control Showing Dim combo Box Column As Data Grid View Combo Box Column = _ Data Grid View1.
Add("Price", "Price") '---create a new bindingsource control--- Dim bindingsource As New Binding Source '---add the items into the control--- bindingsource. Header Text = "Types" '---data bind it--- combo Box Col.
nt Args)' because they do not have the same signature.

Its much better to use the handles clause unless you are creating the controls on the fly. Its probably one of these that is causing the problem You also have multiple subs handling the same event, is that required?
