關注gridview中的footerrow

Question

我有以下gridview。

<asp:GridView ID="gvMarks" runat="server" AutoGenerateColumns="false" 
    DataKeyNames="MarkId" Width="80%" onrowdatabound="gvMarks_RowDataBound" 
    ShowFooter="True" onrowcommand="gvMarks_RowCommand"> 
    <Columns> 
     <asp:TemplateField> 
      <HeaderTemplate> 
       SubjectCode 
      </HeaderTemplate> 
      <FooterTemplate> 
      <asp:DropDownList ID="dlSubjectCode" runat="server" width="100px" AutoPostBack="false"></asp:DropDownList> 
      </FooterTemplate> 
     </asp:TemplateField> 
     <asp:TemplateField> 
      <HeaderTemplate> 
       Mark 
      </HeaderTemplate> 
       <FooterTemplate> 
       <asp:TextBox ID="txtInternalMark" runat="server" ></asp:TextBox> 
      </FooterTemplate> 
     </asp:TemplateField> 

     <asp:TemplateField> 
      <HeaderTemplate> 
       Insert 
      </HeaderTemplate> 
      <FooterTemplate> 
       <asp:LinkButton ID="lnkInsert" runat="server" Text="Insert" 
        CommandName="Insert" ></asp:LinkButton> 
      </FooterTemplate> 
     </asp:TemplateField> 
    </Columns> 
    <FooterStyle BackColor="White" ForeColor="#000066" /> 
    <RowStyle ForeColor="#000066" /> 
    <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> 
    <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" /> 
    <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> 
</asp:GridView> 

如果我進入txtInternalMark一定的價值，IAM不代碼behind.Iam歌廳它的價值歌廳值「」 .Iam使用下面的代碼

if (e.CommandName.Equals("Insert")) 
{ 
    TextBox txtInternalMark = (TextBox)gvMarks.FooterRow.FindControl("txtInternalMark"); 
    lblMessage.Text = txtInternalMark .Text; 
} 

能

任何人的幫助來獲取值代碼隱藏中的文本框。

海，

string Ingredient = ((TextBox) gvMarks.FooterRow.FindControl("txtInternalMark")).Text; 

Response.Write(Ingredient); 

，如果它不工作增加CausesValidation="False"到UR的LinkBut​​ton lnkInsert
