如何从ASP GridView页脚获取所有值

Question

I have been fighting this problem all day. I have a asp:Gridview with several footer Templates that has several TextBox fields, a DropDown and a CheckBox. I hide the footer until the add records asp:button is clicked. That all works and I can enter data in the text boxes, chose elections from the drop down and cycle the checkbox. Now when I try to save the data to the database I use this code.

protected void MembersGridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName.Equals("EmptyInsert"))
    {

    }

    if (e.CommandName.Equals("Insert"))
    {

        int Role =Convert.ToInt32((MembersGridView.FooterRow.FindControl("ddlRole") as DropDownList).SelectedItem.Value);
        string FirstName = (MembersGridView.FooterRow.FindControl("txtLastName") as TextBox).Text;
        string LastName = (MembersGridView.FooterRow.FindControl("txtLastName") as TextBox).Text;
        TextBox UserName = MembersGridView.FooterRow.FindControl("txtUserName") as TextBox;
        TextBox Email = MembersGridView.FooterRow.FindControl("txtEmail") as TextBox;
        CheckBox active = MembersGridView.FooterRow.FindControl("chkActive") as CheckBox;
        DbContext.AAHMembersAdd(Role, FirstName, LastName, UserName.Text, Email.Text, active.Checked);

        //MembersGridView.EditIndex = -1;

        MembersGridView.DataSource = DbContext.VW_Members.ToList(); 
        DataBind();
    }
}

<asp:TemplateField HeaderText="First Name" ItemStyle-Width="100">
   <ItemTemplate>
        <asp:Label ID="lblFirstName" runat="server" Text='<%# Eval("firstname")%>'></asp:Label>
   </ItemTemplate>
   <EditItemTemplate>
        <asp:TextBox ID="txtFirstName" runat="server" Text='<%# Eval("firstname")%>'></asp:TextBox>
   </EditItemTemplate>
   <FooterTemplate>
       <asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox>
   </FooterTemplate>
</asp:TemplateField>

I have added the aspx for one of the Template fields all are the same as this one except the drop down and CheckBox

The DropDown and the CheckBox data is returned however all of my TextBox values are returned as an empty string. What am I missing here. As you can see I have already tries a couple of different ways but the results are the same.

From what I can see; you are not setting the text to anything - therefore the textbox.text value is an empty string. Try changing this code:

<FooterTemplate> <asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox> </FooterTemplate>

to this:

<FooterTemplate> <asp:TextBox ID="txtFirstName" text="hello" runat="server"></asp:TextBox> </FooterTemplate>

also change this:

string FirstName = (MembersGridView.FooterRow.FindControl("txtLastName") as TextBox).Text;

to this:

 string FirstName = (MembersGridView.FooterRow.FindControl("txtFirstName") as TextBox).Text;
