Hello luca,

Please find the answer to your question in the support ticket that you have opened: Change property cell into new row.

Essentially, you should use the ViewCellFormatting event to change properties of cells in a new row:
void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)     
{     
    if (e.CellElement.ColumnIndex == 0 && e.CellElement.RowInfo is GridViewNewRowInfo)     
    {     
        e.CellElement.BackColor = Color.Gray;     
        e.CellElement.GradientStyle = GradientStyles.Solid;     
        e.CellElement.DrawFill = true;     
    }     

I hope this helps. If you have additional questions, feel free to contact us.

All the best,
Nikolay

Hi 

I have used this code for changing the color of particular cell in RadGridView

if (e.Column.Name == "CATCOLOR")
          {
              if (e.CellElement.RowInfo.Cells["Color"].Value != DBNull.Value)
              {
                  e.CellElement.Font = new Font("Segoe UI", 9, FontStyle.Bold);
                  e.CellElement.ForeColor = Color.FromArgb(Convert.ToInt32(e.CellElement.RowInfo.Cells["Color"].Value));
                 // return;
              }
              else
              {
                  e.CellElement.ResetValue(LightVisualElement.ImageProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.ImageAlignmentProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.TextImageRelationProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
                  e.CellElement.ResetValue(LightVisualElement.FontProperty, ValueResetFlags.Local);
              }
          }

when I using horizental scroll bar for scrolling the colors other cells forecolor changes instead of desired column!

Hi Vahid,

Thank you for writing.

It looks like you need one more else clause handling the case when you are not in the CATCOLOR column. Please check the following example: http://docs.telerik.com/devtools/winforms/gridview/cells/formatting-cells#example-cells-background-formatting.

I hope this helps. Should you have further questions please do not hesitate to write back.
