RadGrid Change master table cell BackGround Color

[PJ]

Hi,

I have a hierarichal grid and I'm trying to change the parent row cell color. The below code is working fine for changing the background color of a cell. But when I click on the expand arrow it is not expanding the detail table. If I comment out this code, it expands fine.

What am I doing wrong? Suggessions please....


protected void RadGridResults_ItemDataBound(object sender, GridItemEventArgs e)
        {
if (e.Item is GridDataItem)
                    {
                        GridDataItem dataItem = (GridDataItem)e.Item;
                        if (dataItem["rpd_cott_ind"].Text == "COTT")
                        {
                            dataItem["rpd_cott_ind"].BackColor = System.Drawing.Color.Brown;
                            dataItem["rpd_cott_ind"].Font.Bold = true;
                        }
                    }
}

Thanks,
PJ.

Hello PJ,

You would have to differentiate between the MasterTableView and the child table using their name properties. Check the following code out and see if it helps in your scenario:
aspx:

<telerik:RadGrid ID="RadGridResults" DataSourceID="SqlDataSource1" runat="server" onitemdatabound="RadGridResults_ItemDataBound">
   <MasterTableView Name="Master" CommandItemDisplay="Top"  DataSourceID="SqlDataSource1">
       <DetailTables>
           <telerik:GridTableView Name="Detail" DataSourceID="SqlDataSource2" runat="server">

c#:

 protected void RadGridResults_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem && e.Item.OwnerTableView.Name=="Master")
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            if (dataItem["rpd_cott_ind"].Text == "COTT")
            {
                dataItem["rpd_cott_ind"].BackColor = System.Drawing.Color.Brown;
                dataItem["rpd_cott_ind"].Font.Bold = true;
            }
        }
    }

Thanks
Princy.

Thank you. Your logic is working. I appreciate your help!

After posting the question, I digged into it little bit more and tried this way. Using "foreach" loop resolved the issue too.
                   
                    foreach (GridDataItem dataitem in RadGridResults.MasterTableView.Items)
                    {
                        if (dataItem["rpd_cott_ind"].Text == "COTT")
                        {
                            dataItem["rpd_cott_ind"].BackColor = System.Drawing.Color.Brown;
                            dataItem["rpd_cott_ind"].Font.Bold = true;
                        }
                    }
Thanks,
PJ.

Hi, I am using the same logic and it's working for me but I have set BackColor = "Gray" on all the columns. So when it loads the grid it shows Gray color instead of showing the color I set on condition. How can I solve this ?

Hi,

I would advise you to use CSS in order to set styles to your RadGrid control. This way you have more control on how they are applied:
