resizeToFit

This method resizes the column to fit the widest cell's content without wrapping. It also provides two optional parameters which can be used for further alteration:

• skipHeaderCell - Determines whether the Headers should be ignored in the calculation for the column's new width.By default - false.

• includeAllHeaderRows - This parameter has effect only if the skipHeaderCell is set to false. It determines whether the cells of the filter item should be considered in the calculation for the column's new width.By default - false, except when the RadGrid has structure with Multi-column headers configured.

In order to enable the resizing of the columns you will need to configure also the following properties:

• AllowColumnResize="true" - enables the column resizing functionality.
• AllowResizeToFit="true" - enables the resize to fit functionality.
• ResizeGridOnColumnResize="false" - stops the automatic resizing of the columns after every resizeToFit() call.
