Hello Sandeep,

Please test the following snippet:

protected void Page_Load(object sender, EventArgs e)
{
    GridCheckBoxColumn checkBoxColumn = new GridCheckBoxColumn();
    RadGrid1.MasterTableView.Columns.Add(checkBoxColumn);
    checkBoxColumn.UniqueName = "myCheckBoxColumn";
    checkBoxColumn.HeaderText = "CheckBox Column";
}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        CheckBox checkBox1 = (CheckBox)((GridDataItem)e.Item)["myCheckBoxColumn"].Controls[0];
        checkBox1.Checked = true;
    }
}

That is pretty slick.

How would I let the user check or uncheck the boxes at their leisure? I've tried setting the ReadOnly property of the column but it is stilled greyed out and not editable.

Thanks

Hello Kris,

You can either access the checkboxes and enable it in the code behind or use TemplateColumns with checkboxes in the ItemTemplate. Here's the code to enable checkboxes for a checkboxcolumn:
c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            CheckBox checkBox1 = (CheckBox)((GridDataItem)e.Item)["CheckBoxColumnUniqueName"].Controls[0];
            checkBox1.Enabled = true;
        }
    }

Thanks
Princy.
