RadGridView Column Header doesn't auto change width

Updated on Sep 15, 2025

Environment

Product Version	2019.1 220
Product	RadGridView for WPF

Description

When I change RadGridView column header from a longer to a shorter string, the column header width doesn't change its size to autofit.

Solution

To make the header fit its content, reset the Width of the column when the Header changes.

C#

	public void MethodCalledWhenTheHeaderPropertyChanges()
	{
		var column = this.radGridView.Columns[0];
		column.Width = new GridViewLength(1, GridViewLengthUnitType.Pixel);
		column.Width = new GridViewLength(1, GridViewLengthUnitType.Auto);
	}
