Editors

RadVirtualGrid allows the users to edit the cells values. Usually this process starts by typing in the cell or by pressing F2. By default the editor type is determined according to the data value type. When in edit mode, the user can change the cell value and press Enter to commit the change or Esc to revert to the original value. Clicking outside the edited cell also commits the change.

RadVirtualGrid can be made read-only by setting the AllowEdit property to false. In this case the editors would not appear.

Currently, RadVirtualGrid supports the following editors out of the box:

RadVirtualGrid exposes an API for defining the data types of its columns. If the data type is explicitly set it wil determine the cell editors used in this column. Otherwise, the editor is determined by the cell value. The API works by column index.

Defining a Columns`s Data Type

this.radVirtualGrid1.MasterViewInfo.ColumnDataTypes[0] = typeof(int);

Me.radVirtualGrid1.MasterViewInfo.ColumnDataTypes(0) = GetType(Integer)

Reading a Columns`s Data Type

Type dataType = this.radVirtualGrid1.MasterViewInfo.GetColumnDataType(1);

Dim dataType As Type = Me.radVirtualGrid1.MasterViewInfo.GetColumnDataType(1)
