Hi all,

I have a grid that on the ItemDataBound event I am checking some dates and turning the rows either yellow or red if the those corresponding dates are past the current date.  The test data I am using should make it so every row is red, however, only my alternating rows are turning red.  When I step through the code I can see that the code is being executed for every row so sometime between the time the code executes and the grid finishes loading the row color for some of the rows is being set back to white.

if ((e.Item.ItemType == GridItemType.Item) || (e.Item.ItemType == GridItemType.AlternatingItem))
{
    GridDataItem dataBoundItem = e.Item as GridDataItem;
  
    DateTime currentDate = DateTime.Now;
    DateTime dtRed = Convert.ToDateTime(DateToRed);
    DateTime dtYellow = Convert.ToDateTime(DateToYellow);
  
    //test data this should turn all rows red.//
    dtYellow = Convert.ToDateTime("08/25/2011");
    dtRed = Convert.ToDateTime("9/01/2011");
  
    System.TimeSpan diffRed = currentDate.Subtract(dtRed);
    System.TimeSpan diffYellow = currentDate.Subtract(dtYellow);
  
    if (diffYellow.Days >= 1)
    {
        dataBoundItem.BackColor = System.Drawing.Color.Yellow;
    }
  
    if (diffRed.Days >= 1)
    {
        dataBoundItem.BackColor = System.Drawing.Color.Red;
    }
}

            </MasterTableView>
            <HeaderStyle BackColor="#666666" Font-Names="verdana, arial" Font-Size="Small" Height="20px" />
            <FilterItemStyle BackColor="#ffffff" />
        </telerik:RadGrid>

It is definately related to a conflict with the skin I am using because if I remove the skin, the color change code works fine.

Any ideas would be greatly appreciate.   Attached is an image of part of the grid that shows the dates.  The dates are the same for each line so the color should be red for each of them.

Thanks,

Rhonda

Hello Rhonda,

There is a CSS rule (.RadGrid_WF .rgRow TD) that overrides the background color.

Please try the following workaround:
if (diffRed.Days >= 1)
{
    dataBoundItem.CssClass += " wfRedHighlight";
}

<style type="text/css">
    tr.wfRedHighlight td
    {
        background-color: Red;
    }
</style>
