GridView Footer

snufse · May 20th, 2009, 03:39 PM

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. I would like to be able to have a ShowSelectButton on the Footer as well, let user be able to click and then call a stored procedure. Is this possible. I have tried to add an attribute to the footer cell but not be able to get it working

Code:

 
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")
EndIf

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

Code:

 
ProtectedSub GridView1_RowDataBound(ByVal sender AsObject, 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")
EndIf
EndSub

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

Code:

 
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
