Highlight grid column

[Aleksandr]

Hello.
I'm using RadGridView control where I use columns as dates in month like:
| 1 | 2 | 3 |...... | 31 |
I need a way to highlight 'today' column.
Thank you in advance.

Hi Aleksandr,

Thank you for writing.

To do that you should set the grid SelectionMode to CellSelect, and the just select the desired cells:

radGridView1.SelectionMode = GridViewSelectionMode.CellSelect;
foreach (GridViewRowInfo row in radGridView1.Rows)
{
    row.Cells["MyColumn"].IsSelected = true;
}

I hope this helps.

Thank you. But when I click on some cell then highlighted cells lose their selection.
I need 'today' column to be highlighted all the time, maybe by changing its cells border. Can you help me, please?

Hello and thank you for the clarification.

In this case you should use the formatting events of RadGridView. Here is a small sample

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (e.Column.Name == "DecimalColumn")
            {
                e.CellElement.DrawFill = true;
                e.CellElement.BackColor = Color.Red;
            }
            else
            {
                e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
                e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
            }
        }

Similarly, you can introduce any modification you want. Here you can find more information about the formatting events: http://www.telerik.com/help/winforms/gridview-cells-formatting-cells.html.

I hope that you find this information useful.
