When you bind a DataGridView control and set the AutoGenerateColumns property to true, columns are automatically generated using default column types appropriate for the data types contained in the bound data source.
You can also create instances of any of the column classes yourself and add them to the collection returned by the Columns property. You can create these instances for use as unbound columns, or you can manually bind them. Manually bound columns are useful, for example, when you want to replace an automatically generated column of one type with a column of another type.
The following table describes the various column classes available for use in the DataGridView control:
|
Class |
Description |
|
DataGridViewTextBoxColumn |
Used with text-based values. Generated automatically when binding to numbers and strings. |
|
DataGridViewCheckBoxColumn |
Used with Boolean and CheckState values. Generated automatically when binding to values of these types. |
|
DataGridViewImageColumn |
Used to display images. Generated automatically when binding to byte arrays, Image objects, or Icon objects. |
|
DataGridViewButtonColumn |
Used to display buttons in cells. Not automatically generated when binding. Typically used as unbound columns. |
|
DataGridViewComboBoxColumn |
Used to display drop-down lists in cells. Not automatically generated when binding. Typically data-bound manually. |
|
DataGridViewLinkColumn |
Used to display links in cells. Not automatically generated when binding. Typically data-bound manually. |
|
Your custom column type |
You can create your own column class by inheriting the DataGridViewColumn class or any of its derived classes to provide custom appearance, behavior, or hosted controls.
