To reproduce:

this.radGridView1.EnableFiltering = true;
this.radGridView1.BestFitColumns();

DataTable dt = new DataTable();    
dt.Columns.Add(new DataColumn("Column 1", Type.GetType("System.Decimal")));
dt.Columns.Add(new DataColumn("Column 2", Type.GetType("System.Decimal")));
dt.Columns.Add(new DataColumn("Column 3", Type.GetType("System.String")));

for (int i = 0; i < 20; i++)
{
    dt.Rows.Add(0, i, "Text " + i);
}

this.radGridView1.DataSource = dt;
this.radFilterView1.AssociatedControl = this.radGridView1;

Run the project and filter the first column ("Column 1") by dragging radFilterViews radTrackBar.

You will get the following exception: "System.ArgumentOutOfRangeException: 'Value of '1' is not valid for 'Value'. 'Value' should be between 'Minimum' and 'Maximum'."
