How to add footer to gridview - asp.net

Question

I have a grid with 3 columns - Edit, ID, Movie. I would like to add a footer with an Insert link button, 2 textboxes respectively, but unable to do so. Is it possible.
ASPX:
<asp:GridView ID="gridview1" runat="server" AutoGenerateColumns="False"
OnRowEditing="gridview1_RowEditing"
OnRowCancelingEdit="gridview1_RowCancelingEdit"
ShowFooter="true" >
<Columns>
<asp:CommandField ShowEditButton="true" ShowDeleteButton="true" />
<asp:BoundField DataField="id" HeaderText="ID" />
<asp:BoundField DataField="movie" HeaderText="MOVIE" />
</Columns>
</asp:GridView>
When I try the following, there is an error for commandfield which says, this element is not supported.
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CommandField ShowEditButton="true" ShowDeleteButton="true" />
</ItemTemplate>
<FooterTemplate>
<asp:LinkButton ID="lnkInsert" runat="server" Text="Insert"></asp:LinkButton>
</FooterTemplate>
</asp:TemplateField>
</columns>
The other way would be to use itemTemplate & EditTemplate for each column control. But I find this simple and would like to proceed this way. So Can I add a footer to this structure.

Answer 1

YES, It is possible. But this will require using the <FooterTemplate> inside <TemplateField>. Use TemplateFields for each of the columns and also set the FooterTemplate for each of the columns.
NOTE: The ID column seems here to be a Primary Key. So remove the <FooterTemplate> from the corresponding <TemplateField> defined for ID column, if ID is a Primary Key OR an autogenerated field in your database.
NOTE II: The <FooterTemplate> simply will contain a TextBox only.
<Columns>
<asp:TemplateField>
<EditItemTemplate>
<asp:LinkButton ID="lnkBtnUpdate" runat="server" CausesValidation="True"
CommandName="Update" Text="Update"></asp:LinkButton>
<asp:LinkButton ID="lnkBtnCancel" runat="server"
CausesValidation="False"
CommandName="Cancel" Text="Cancel">
</asp:LinkButton>
</EditItemTemplate>
<FooterTemplate>
<asp:LinkButton ID="lnkBtnInsert" runat="server"
CommandName="Insert">Insert</asp:LinkButton>
</FooterTemplate>
<ItemTemplate>
<asp:LinkButton ID="lnkBtnEdit" runat="server" CausesValidation="False"
CommandName="Edit" Text="Edit"></asp:LinkButton>
<asp:LinkButton ID="lnkBtnDelete" runat="server"
CausesValidation="False"
CommandName="Delete" Text="Delete">
</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ID">
<EditItemTemplate>
<asp:TextBox ID="TextBoxID" runat="server" Text='<%# Bind("ID") %>'>
</asp:Label>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("ID") %>'>
</asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtID" runat="server"></asp:TextBox>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="MOVIE">
<EditItemTemplate>
<asp:TextBox ID="TextBoxMovie" runat="server" Text='<%# Bind("Movie") %>'></asp:TextBox>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtMovie" runat="server"></asp:TextBox>
</FooterTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("Movie")%>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
Now there are 2 ways to insert Data. Either you can use GridView OnRowCommand event or you can handle the OnClick event of your Insert button.

Answer 2

You can't place a commandfield inside TemplateField. But can do like this:
<asp:GridView ID="gridview1" runat="server" AutoGenerateColumns="False"
OnRowEditing="gridview1_RowEditing"
OnRowCancelingEdit="gridview1_RowCancelingEdit"
ShowFooter="true" >
<Columns>
<asp:TemplateField>
<ItemTemplate>
<!--To fire the OnRowEditing event.-->
<asp:LinkButton ID="lbEdit" runat="server" CommandName="Edit"
Text="Edit">
</asp:LinkButton>
<!--To fire the OnRowDeleting event.-->
<asp:LinkButton ID="lbDelete" runat="server" CommandName="Delete"
Text="Delete">
</asp:LinkButton>
</ItemTemplate>
<FooterTemplate>
<asp:LinkButton ID="lnkInsert" runat="server" Text="Insert"></asp:LinkButton>
</FooterTemplate>
</asp:TemplateField>
<asp:BoundField DataField="id" HeaderText="ID" />
<asp:BoundField DataField="movie" HeaderText="MOVIE" />
</Columns>
</asp:GridView>
