    Hello Babu,

    You can do this in OnSelectedIndexChanged event of RadComboBox. Access the column and based on the SelectedItem(color) of RadComboBox, change the text color of column. Sample code is given below for your reference. Change the logic according to your requirement.

    ASPX:
    <telerik:GridTemplateColumn>
        <EditItemTemplate>
            <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
                <Items>
                    <telerik:RadComboBoxItem Text="--Select--" Value="0" />
                    <telerik:RadComboBoxItem Text="Yellow" Value="1" />
                    <telerik:RadComboBoxItem Text="Red" Value="2" />
                    <telerik:RadComboBoxItem Text="Green" Value="3" />
                </Items>
            </telerik:RadComboBox>
        </EditItemTemplate>
    </telerik:GridTemplateColumn>
    <telerik:GridBoundColumn DataField="ProjectHealth" UniqueName="ProjectHealth" HeaderText="Project Health">
    </telerik:GridBoundColumn>

    C#:
    protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
       {
           RadComboBox combo = (RadComboBox)o;
           switch (combo.SelectedItem.Text)
           {
               case "Yellow":
                    RadGrid1.MasterTableView.GetColumn("ProjectHealth").ItemStyle.ForeColor = System.Drawing.Color.Yellow;
                   break;
               case "Red":
                   RadGrid1.MasterTableView.GetColumn("ProjectHealth").ItemStyle.ForeColor = System.Drawing.Color.Red;
                   break;
               case "Green":
                   RadGrid1.MasterTableView.GetColumn("ProjectHealth").ItemStyle.ForeColor = System.Drawing.Color.Green;
                   break;
           }
       }

    Thanks,
    Princy.

    I tried another way .. That is also working ... I am just posting here... If anybody wants... Here is the code...


    protected void gvPjtMnt_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem dataItem = e.Item as GridDataItem;
                TableCell myCell = dataItem["ProjectHealth"];
                myCell.Font.Size = 10;
                myCell.Font.Bold = true;
     
                if (myCell.Text.Trim() == "GREEN")
                {
                    myCell.ForeColor = System.Drawing.Color.Green;
                }
                if (myCell.Text.Trim() == "RED")
                {
                    myCell.ForeColor = System.Drawing.Color.Red;
                }
                if (myCell.Text.Trim() == "YELLOW")
                {
                    myCell.ForeColor = System.Drawing.Color.Yellow;
                }
            }

        }

    And how can I change a cell font color based on the value of another colum?

    For example I have a row with 

    Product - Sold

    and I have to change the color of the Product if Sold has 0 or 1 value. 

    Thank you. 

    Luis

    Hello Luis,

     

    You can use the following approach to change the color:
    https://www.telerik.com/forums/alternatingitemstyle-5e16887f3085#odVQBomUikiIJfrxeBQrww

    And for getting the value of Sold, you can use the DataBinder.Eval approach:
    https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/accessing-values-and-controls/server-side/accessing-cells#accessing-raw-field-data-and-key-values

    Hope this helps.
