CellFormatting doesn't allow BackColor to be set?

[rich c]

I posted this before but the post seems to have vanished

void TelerikRadGridViewEnhanced_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
        {
            if(!(e.CellElement.RowElement is Telerik.WinControls.UI.GridTableHeaderRowElement) && TextColorOverrideFunction != null)
            {
                e.CellElement.ForeColor  = TextColorOverrideFunction((e.CellElement.RowInfo.DataBoundItem as DataRowView).Row);

            }
      }

This works fine and sets the foreground (text) color. However despite there being 4 BackColor properties, I can't change the back color, it is overridden by the theme. Is there a way to set the BackColor? Thanks

Hi Subh,

By default the painting of cell background is disabled. You should enable it by setting DrawFill property to true. In addition, you can select different background style by setting GradientStyle property. Here is a sample:

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    GridViewDataColumn column = e.CellElement.ColumnInfo as GridViewDataColumn;
    if (column != null && column.UniqueName == "Column1")
    {
        e.CellElement.DrawFill = true;
        e.CellElement.BackColor = Color.Red;
        e.CellElement.GradientStyle = GradientStyles.Solid;
    }
}

I hope this helps. Should you have other questions, I will be glad to help.

I populate the grid with data from an xml node list, I use a for loop to search for rows that need update.  I also want to change the backcolor of some cells in the same operation.  I can not get the backcolor to change, I have tried dozens of ways, unable to figure it out.  Any help is appreciated.

Here is the code:

For Each row As XmlNode In xnl_02

    For Each gvdri As GridViewDataRowInfo In Me.rgv.Rows

        If gvdri.Tag = row(0).InnerText Then
            gvdri.Cells("02_").Value = FormatSystemName(row("device_id").InnerText)
            gvdri.Cells("02_").Value = row("p_id").InnerText

            With (gvdri.Cells("01_").Style)
                .ForeColor = Color.Red
                .Font = New Font("Segoe UI", 8.25, FontStyle.Bold)
                .DrawFill = True
                .GradientStyle = GradientStyles.Solid
                .BackColor = Color.Red
            End With

        End If
    Next

Hello Coby,

When customizing a large number of cells, the best option is to handle the CellFormatting event like demonstrated in this thread. However, if you prefer to use the Style property, you should set also the CustomizeFill property. Consider the sample below:

For Each row As XmlNode In xnl_02

    For Each gvdri As GridViewDataRowInfo In Me.rgv.Rows

        If gvdri.Tag = row(0).InnerText Then
            gvdri.Cells("02_").Value = FormatSystemName(row("device_id").InnerText)
            gvdri.Cells("02_").Value = row("p_id").InnerText

            With (gvdri.Cells("01_").Style)
                .ForeColor = Color.Red
                .Font = New Font("Segoe UI", 8.25, FontStyle.Bold)
                .DrawFill = True
                .GradientStyle = GradientStyles.Solid
                .BackColor = Color.Red
                .CustomizeFill = True
            End With

        End If
    Next
