Hello Luca,
Thank you for writing.
In order to accomplish your task, you will need to best fit the columns first and calculate what the remaining space would be. Then you can adjust the width of the desired column according to your local setup. Please check my code snippet below:
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();
this.radGridView1.DataSource = this.GetData();
this.radGridView1.BestFitColumns(BestFitColumnMode.AllCells);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
int desiredWidth = this.radGridView1.TableElement.Size.Width - this.radGridView1.TableElement.VisualRows[0].Size.Width - this.radGridView1.TableElement.VScrollBar.Size.Width;
this.radGridView1.Columns[2].Width += desiredWidth;
this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
}
private DataTable GetData()
{
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(int));
dt.Columns.Add("Text", typeof(string));
dt.Columns.Add("IsChecked", typeof(bool));
dt.Columns.Add("DateTime", typeof(DateTime));
for (int i = 0; i < 100; i++)
{
dt.Rows.Add(i, "Text " + i, i % 2 == 0, DateTime.Now);
}
return dt;
}
}
I am also attaching a short video showing the result on my end.

Hristo
