Various Built-in Column Editors

This example and this one demonstrate how to configure various built-in column editors for updating/inserting records in RadGrid.

Telerik RadGrid supports all widely used column types as well built-in columns with other controls as editors (RadDatePickers, RadDateInput, RadNumericTextBox, RadMaskedTextBox, RadComboBox, RadEditor and RadUpload). Thus you can define that the new data entries input by the end user will have an automatic filter criteria set and at the same time expose richer user experience. In addition, two-way data-binding is supported out-of-the-box and you do not need to write a single line of code to update/insert/delete records in the grid having any column editor type (see the source code under the tabs below).

The supported column types with other controls as editors are listed below:

GridDateTimeColumn - with option to choose RadDatePicker, RadDateTimePicker, RadTimePicker or simply RadDateInput as editor. To choose the editor type use the PickerType property of the column
GridDropDownColumn - with option to choose standard MS DropDownList or RadComboBox as editor. To choose the editor type use the DropDownControlType property of the column
GridNumericColumn - with RadNumericTextBox as editor
GridMaskedColumn - with RadMaskedTextBox as editor
GridHTMLEditorColumn - with RadEditor control for editing
GridBinaryImageColumn - with RadUpload control for image upload
