Without extra work, the Editor Registry knows how to edit booleans, integers (signed and unsigned of all sizes), floats, doubles, Date Time, and strings. If you wish to edit a different type of object (or change the editor for one of the above types), you can do this through If you want something more surgical, you can have complete control over the process by listening for a cell editing starting event, Cell Edit Starting.

Within the handler for this event, the programmer can create and configure any sort of widget they like and then return this widget via the property will be set with a text representation of the cells value.

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.

When the user has finished editing the value in the cell, the new value will be written back into the model object (if possible). Postcode”) only the last property needs to be writable.

To get the modified value, the default processing tries to use the is dotted (e.g. If none of these three things happen, the user’s edit will be discarded.

In this case, you need to add a Combo Box to the cells in the desired column. 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. Add("Type C") '---create a combobox column--- Dim combo Box Col As New Data Grid View Combo Box Column '---set the header--- combo Box Col.

List Views are normally used for displaying information.The standard List View allows the value at column 0 (the primary cell) to be edited, but nothing beyond that. Depending on how the data for a cell is sourced, the edited values can be automagically written back into the model object. Be aware, though, that this may create some surprises, resulting in user complaints like “How come I can’t edit this value by clicking on it like I can on all the other cells? Once a cell editor is active, the normal editing conventions apply: .
