change color of the cell when its value was changed

[Sam]

How to change the color of the cell when I changed its value?

rgv.CurrentRow.Cells[title].Value = newValue;

Is it possible?

Hi Jei,

Thank you for writing.

You can use the CellValueChanged event of RadGridView, where you can store the cell's column name in the RowInfo.Tag and then in the CellFormatting event, you can check the tag and style the cell accordingly:

void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    if (e.Row.Tag != null && e.Row.Tag.ToString().Contains(e.Column.Name))
    {
        e.CellElement.DrawFill = true;
        e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
        e.CellElement.BackColor = Color.Red;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, Telerik.WinControls.ValueResetFlags.Local);
    }
}

void radGridView1_CellValueChanged(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    if (e.Row.Tag == null)
    {
        e.Row.Tag = e.Column.Name;
    }

    if (!e.Row.Tag.ToString().Contains(e.Column.Name))
    {
        e.Row.Tag += e.Column.Name;
    }
}

I hope this helps.
 
All the best,
