Datagrid cellvalidating event

Data Source = bindingsource '---add a combobox column to the Data Grid View control--- Data Grid View1. Add(combo Box Col) The previous code showed how you can bind a Binding Source control (containing a list of items to let the users choose) to a Data Grid View Combo Box Column control inside a Data Grid View control. 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.

Cancel = true (which would be awesome) is not available in this event.

The following code snippet adds a Combo Box control to the fifth column of the Data Grid View control: '---add columns to the Data Grid View control--- Data Grid View1.

An alternative way would be to add the items to the Data Grid View Combo Box Column control directly, as shown: '---adding columns--- Data Grid View1.

I want to refactor this code that is currently in a partial Form Class and deals with edits made on certain cells in a datagridview (in this case called dgv Replenish).

I would like to refactor so that I can create unit tests to be able to test the logic that effects changing the back color of cells, and updating other cells.

If you decide later (once you have an idea of how to better design your code), to test after the fact, that's fine.

The important thing right now is to separate the concerns. It's more or less the default design pattern for Win Forms.Hi all, I need to override the event that is fired when I hit the Enter key in a datagrid.By default, it skips the current cell and places the focus in the row below.The problem I am having is how to refactor logic to an external class, that has references to the winform controls.Form All following code is part of private string last Edited Cell Value; private void dgv Replenish_Cell Begin Edit(object sender, Data Grid View Cell Cancel Event Args e) private void dgv Replenish_Cell Validating(Object sender, Data Grid View Cell Validating Event Args e) private void dgv Replenish_Cell Clicked(object sender, Data Grid View Cell Event Args e) private void dgv Replenish_Cell Formatting(object sender, Data Grid View Cell Formatting Event Args e) private void dgv Replenish_Cell Value Changed(object sender, Data Grid View Cell Event Args e) The truth is, it's really very hard to refactor this code out of the code behind once it's been written like this.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.
