What is the method for changing the background color of rows in a grid

Within my asp.net application, I am implementing a grid-view control where I am populating data into a label element within the grid-view.
If the data happens to be empty, I want the row color to be displayed in red.
However, if there is data to bind, I would like the row color to be green. Here is the code snippet I am using:

<asp:TemplateField HeaderText="Holiday Region">
     <ItemTemplate>
         <asp:Label ID="lblholdareg" runat="server" Text='<%# Eval("Holidaregion") %>'>
         </asp:Label>
     </ItemTemplate>
</asp:TemplateField>

Answer №1

To customize the appearance of rows in a GridView, utilize the RowDataBound event. Access the e.Row item and apply a CSS class or set the background color directly. Using a CSS class allows for easier design modifications without the need for recompilation.

<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound">
    <Columns>
        <asp:TemplateField HeaderText="Holiday Region">
            <ItemTemplate>
                <asp:Label ID="lblholdareg" runat="server" Text='<%# Eval("Holidaregion") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

In the code-behind, assuming a DataTable is used as the data source. Adjust the code according to your data structure:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    System.Data.DataRow row = (System.Data.DataRow)e.Row.DataItem;
    if (row["Holidaregion"] == null || row["Holidaregion"].ToString().Trim().Length == 0)
    {
        e.Row.CssClass = "row-empty";
    }
    else 
    {
        e.Row.CssClass = "row-full";
    }
}

Answer №2

To achieve this, you need to utilize the rowdatabound function within the context of a gridview.

protected void RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
         //Adjust the code based on cell number or element identification
         if(e.Row.Cells[0].Text != "")
            e.Row.BackColor = Color.Green;
         else
            e.Row.BackColor = Color.Red;   
    }
}

Consider trying out the following approach

<asp:TemplateField HeaderText ="Holiday Region">
  <ItemTemplate >
    <asp:Label ID ="lblholdareg" runat ="server"
     CSSClass='<%# (String.IsNullOrEmply(Eval("Holidaregion")))?"red:green" %>' 
     Text ='<%# Eval("Holidaregion") %>' >  
    </asp:Label>

   </ItemTemplate>
</asp:TemplateField>

Updates:

Instead of struggling with inline grid view and server-side code, consider utilizing jQuery to achieve the same result on the client side
