Hello,

Thank you for contacting us.

The desired functionality can be achieved by using the the CellFormatting event:

public Form1()
{
    InitializeComponent();
    radGridView1.Columns.Add(new GridViewCheckBoxColumn("CheckBox") { EditMode = EditMode.OnValueChange });
    radGridView1.DataSource = GetTable();
    radGridView1.CellFormatting += radGridView1_CellFormatting;
}

void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    if (e.Column.Name != "CheckBox")
    {
        if (e.Row.Cells[0].Value != null && (bool)e.Row.Cells[0].Value )
        {
            e.CellElement.Enabled = true;
        }
        else
        {
            e.CellElement.Enabled = false;
            e.CellElement.Text = "";
        }
    }
}

More information about this event can be found here: Formatting Cells.

Please let me know if there is something else I can help you with.

Hi Free,

Thank you for writing back.

You can update the CellFormatting event and skip the text clearing for the second column:

void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    if (e.Column.Name != "CheckBox")
    {
        if (e.Row.Cells[0].Value != null && (bool)e.Row.Cells[0].Value )
        {
            e.CellElement.Enabled = true;
        }
        else
        {
            e.CellElement.Enabled = false;
            if (e.Column.Name !="SecondColumnName")
            {
                e.CellElement.Text = "";
            }

        }
    }
}
