Hi Behin,

Thank you for writing.

To achieve the desired functionality, simply subscribe to the Scroll or the ValueChanged event and use following code snippet:

if (this.radTrackBar1.Value > oldValue)
{
    foreach (GridViewColumn item in this.radGridView1.Columns)
    {
        item.Width += (this.radTrackBar1.Value - oldValue) * 5;
    }
}
else
{
    foreach (GridViewColumn item in this.radGridView1.Columns)
    {
        item.Width -= (oldValue - this.radTrackBar1.Value) * 5;
    }
}
oldValue = this.radTrackBar1.Value;

Attached is a sample project.

I hope this information helps. If you have further questions, feel free to write back
