Gets or sets the template for displaying the footer section of a TemplateField object.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public virtual ITemplate FooterTemplate { get; set; }

Property Value

Type: System.Web.UI.ITemplate

A System.Web.UI.ITemplate-implemented object that contains the template for displaying the footer section of a TemplateField. The default is null, which indicates that this property is not set.

Use the FooterTemplate property to specify the custom content displayed in the footer section of a TemplateField object. Define the content by creating a template that specifies how the footer section is rendered.

To specify a template, first place opening and closing <FooterTemplate> tags between the opening and closing tags of the <TemplateField> element. Next, add the custom content between the opening and closing <FooterTemplate> tags. The content can be as simple as plain text or more complex (embedding other controls in the template, for example).

To programmatically access a control defined in a template, first determine which TableCell object in the data-bound control contains the control. Next, use the Controls collection of the TableCell object to access the control. You can also use the FindControl method of the TableCell object to find the control, if the control has an ID property specified.

The following code example demonstrates how to use the FooterTemplate property to create a custom template for the footer section of a TemplateField field column in a GridView control. The template displays the sum of the values in the TemplateField field column.

  // Create a variable to store the order total.
  private Decimal orderTotal = 0.0M;

  void OrderGridView_RowCreated(Object sender, GridViewRowEventArgs e)

    if (e.Row.RowType == DataControlRowType.Footer)

      // Get the OrderTotalLabel Label control in the footer row.
      Label total = (Label)e.Row.FindControl("OrderTotalLabel");

      // Display the grand total of the order formatted as currency.
      if (total != null)
        total.Text = orderTotal.ToString("c");



  void OrderGridView_RowDataBound(Object sender, GridViewRowEventArgs e)

    if (e.Row.RowType == DataControlRowType.DataRow)

      // Get the cell that contains the item total.
      TableCell cell = e.Row.Cells[2];

      // Get the DataBoundLiteralControl control that contains the 
      // data-bound value.
      DataBoundLiteralControl boundControl = (DataBoundLiteralControl)cell.Controls[0];

      // Remove the '$' character so that the type converter works properly.
      String itemTotal = boundControl.Text.Replace("$",  "");

      // Add the total for an item (row) to the order total.
      orderTotal += Convert.ToDecimal(itemTotal);
