GridView Footer - need help

[snufse]

I have an application where user is able to select jobs which will show equipment ID and equipment hours.

I am displaying a GridView that has a CommandField in the 1st column with a ShowSelectButton= True. The user is able to click the select button and a 2nd (detailed) GridView is shown. This works fine.

I have added a Footer to my GridView. I show total equipment hours for the selection (looping through the Data Table). This work fine as well.

Now, the 1st columnt is showing FooterText = "Select". I need to be able to click this column (same way I do in the GridView.Data) and in my code behing capture this click event.

Mark Up Code:

<asp:GridView ID="GridView1" runat="server" Style="z-index: 102; left: 0px; position: relative;
                        top: 43px; border-right: gray thin solid; border-top: gray thin solid; border-left: gray thin solid;
                        border-bottom: gray thin solid; font-size: 12px; overflow: hidden; clip: rect(auto auto auto auto);"
                        Width="342px" AllowPaging="True" AllowSorting="True" Font-Size="Small" AutoGenerateColumns="False"
                        CellSpacing="2" HorizontalAlign="Left" BorderColor="LightGray" BorderStyle="None"
                        PageSize="14" OnSorting="GridView1_Sorting" OnRowCommand="GridView1_RowCommand"
                        EmptyDataText="No records found" ShowFooter="True">
                        <Columns>
                            <asp:CommandField HeaderText="Detail" ShowSelectButton="True" FooterText="Select">
                                <HeaderStyle HorizontalAlign="Center" />
                                <ItemStyle HorizontalAlign="Center" Width="10px" />
                            </asp:CommandField>
                            <asp:BoundField DataField="equipmentID" HeaderText="Equipment ID" SortExpression="equipmentID">
                                <ItemStyle HorizontalAlign="Left" Width="60px" />
                                <HeaderStyle HorizontalAlign="Center" />
                            </asp:BoundField>
                            <asp:BoundField DataField="equipmentname" HeaderText="Equipment Name" FooterText="Total">
                                <HeaderStyle HorizontalAlign="Center" />
                                <ItemStyle HorizontalAlign="Left" Width="240px" />
                                <FooterStyle HorizontalAlign="Right" />
                            </asp:BoundField>
                            <asp:BoundField DataField="hours" HeaderText="Hours" NullDisplayText="0">
                                <ItemStyle HorizontalAlign="Right" Width="80px" />
                                <FooterStyle HorizontalAlign="Right" />
                            </asp:BoundField>
                        </Columns>
                        <HeaderStyle BackColor="#FFC080" Height="35px" />
                        <AlternatingRowStyle BackColor="#FFFFC0" />
                        <SelectedRowStyle BackColor="#FF8080" />
                        <EditRowStyle BackColor="#FF8080" />
                        <RowStyle Height="20px" />
                        <FooterStyle BackColor="#FF8080" />
                    </asp:GridView>

Code Behind:

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles GridView1.RowDataBound

        Dim tabledata As Data.DataRowView = e.Row.DataItem

        If e.Row.RowType = DataControlRowType.Footer Then
            e.Row.Cells(0).Text = "Select"
            e.Row.Cells(2).Text = "Selection Total"
            e.Row.Cells(3).Text = Session("TotalHours")
        End If

    End Sub

Hello,

I am not sure that I follow? What exactly isn't working for you? Or what is it you are trying to do, I think I must have missed something.

OK, I would like to have a select button on the footer row (like I now have on the data rows). The current select button on the data rows calls a stored procedure showing additional details in a new grid view.

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles GridView1.RowDataBound

        Dim tabledata As Data.DataRowView = e.Row.DataItem

        If e.Row.RowType = DataControlRowType.Footer Then
            e.Row.Cells(0).Text = "Select"
            e.Row.Cells(0).Attributes.Add ---> onclick ?         
            e.Row.Cells(2).Text = "Selection Total"
            e.Row.Cells(3).Text = Session("TotalHours")
        End If

    End Sub

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)

        If e.CommandName = "Select" Then

            Dim index As Integer = Convert.ToInt32(e.CommandArgument)
            Dim mySelectedRow As GridViewRow = GridView1.Rows(index)
            Dim mySelectedCell As TableCell

            mySelectedCell = mySelectedRow.Cells(1)
            Equipment_ID = mySelectedCell.Text.ToString

            GetItemDetail(Equipment_ID)
            DisplayItemDetail()

        End If

    End Sub

I managed to add a link button to my gridview footer like this:

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles GridView1.RowDataBound

        Dim tabledata As Data.DataRowView = e.Row.DataItem

        If e.Row.RowType = DataControlRowType.Footer Then
            myLinkButton.Text = "Select"
            myLinkButton.CommandName = "SelectFooter"
            AddHandler myLinkButton.Click, New EventHandler(AddressOf ClickHandler)
            e.Row.Cells(0).Controls.Add(myLinkButton)
            e.Row.Cells(2).Text = "Selection Total"
            e.Row.Cells(3).Text = Session("TotalHours")
        End If

    End Sub

Now my next question is how do I capture the "click" event? I tried this but does not work:

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)

        If e.CommandName = "Select" Then
            Dim index As Integer = Convert.ToInt32(e.CommandArgument)
            Dim mySelectedRow As GridViewRow = GridView1.Rows(index)
            Dim mySelectedCell As TableCell

            mySelectedCell = mySelectedRow.Cells(1)
            Equipment_ID = mySelectedCell.Text.ToString

            GetItemDetail(Equipment_ID)
            DisplayItemDetail()
        End If

        If e.CommandName = "SelectFooter" Then
            AddHandler myLinkButton.Click, New EventHandler(AddressOf ClickHandler)
        End If

End Sub

Public Sub ClickHandler(ByVal sender As Object, ByVal e As EventArgs)

        'Handle LinkButton click event here. But this event never gets called...

End Sub

Couldn't you add the link straight to the Footer's template?

Also, where is myLinkButton defined? Is there a reason it's not being defined in the DataBound event?
