GridViewDataColumn
GridViewDataColumn inherits from GridViewColumn and is the base class for all column types. GridViewDataColumn is an abstract class and you can not use it in its pure form. Below is a list of the column types that RadGridView offers. All of them inherit from the GridViewDataColumn and enhance its capabilities:
| Column's type | Data type |
|---|---|
| GridViewTextBoxColumn | presents String values |
| GridViewDecimalColumn | presents Decimal values |
| GridViewDateTimeColumn | presents DateTime objects |
| GridViewTimeSpanColumn | presents TimeSpan objects |
| GridViewHyperlinkColumn | presents Hyperlinks |
| GridViewColorColumn | presents Colors |
| GridViewCheckBoxColumn | presents Boolean values |
| GridViewImageColumn | presents Images |
| GridViewCalculatorColumn | represents Calculator |
| GridViewCommandColumn | represents Buttons |
| GridViewBrowseColumn | represents File paths |
| GridViewSparklineColumn | represents Sparklines |
| GridViewComboBoxColumn | represents a column whose cells contains comboboxes |
| GridViewMaskBoxColumn | represents a column whose cells contain masked text boxes with String values |
| GridViewRatingColumn | represents a column that visualizes the cell's value by using a rating element |
| GridViewMultiComboBoxColumn | represents a column that contain multi column combo boxes |
By default, RadGridView will generate its columns automatically based on the underlying data source. For example, if the column contains string values, RadGridView will create a GridViewTextBoxColumn, etc. Then, depending on the column's type, RadGridView activates an appropriate editor to handle the cell's value changes. If you have a GridViewTextBoxColumn, the editor is RadTextBoxEditor. A list with all supported editors is available here.
GridViewDataColumn doesn't have associated editor. Each of the above mentioned column types has a default editor.
