Can I Merge Footer In GridView?
Solution 1:
protected void GridView1_OnRowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells.RemoveAt(1);
e.Row.Cells[0].ColumnSpan = 2;
}
}
Solution 2:
untested code
1st footer template should include <%# GetTotal() %>
2nd footer template should be empty
Protected Sub Page_SaveStateComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.SaveStateComplete
Dim DG As GridView = GridView1
Dim Tbl As Table = DG.Controls(0)
Dim tr As GridViewRow
Dim i As Integer
Dim j As Integer
tr = Tbl.Rows(Tbl.Rows.Count - 1) 'this line assume last row is footer row
tr.Cells(0).ColumnSpan = 2 'if you have 3 columns then colspan = 3 instead
For j = 1 To 1 'if you have 3 columns then j = 1 To 2 instead
tr.Cells(j).Visible = False
Next
End Sub
Solution 3:
I was doing something like this - trying to have a button, in the footer span multiple cols.
I ran into a problem when I set columnspan via code, because a) I'm a noob, and b) it was not doing what I expected. I don't remember all the details, but there was some kind of gotcha in there - like it was adding extra columns or something.
Here was my solution. Maybe some of it will be useful. I did in the prerender for the gridview (gvDocs).
And what got it working correctly for me, was programatically removing cells of the footer as well as setting the columnspan.
Even if the code doesn't help, maybe people will get a laugh at the encroaching forgetfulness afflicting me. It makes me laugh sometimes.
Protected Sub gvDocs_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles gvDocs.PreRender
If gvDocs.Rows.Count > 0 Then
Dim m As Integer = gvDocs.FooterRow.Cells.Count
For i As Integer = m - 1 To 1 Step -1
If i <> 8 Then '7 is the number of the column with the applychanges button in it.
gvDocs.FooterRow.Cells.RemoveAt(i)
End If
Next i
gvDocs.FooterRow.Cells(1).ColumnSpan = 6 '6 is the number of visible columns to span.
End If
End Sub
Fernando68 - Here it is in C#
protected void gvDocs_PreRender(object sender, System.EventArgs e)
{
if (gvDocs.Rows.Count > 0) {
int m = gvDocs.FooterRow.Cells.Count;
for (int i = m - 1; i >= 1; i += -1) {
//7 is the number of the column with the applychanges button in it.
if (i != 8) {
gvDocs.FooterRow.Cells.RemoveAt(i);
}
}
gvDocs.FooterRow.Cells[1].ColumnSpan = 6;
//6 is the number of visible columns to span.
}
}

EDITED - Needed to use square brackets to access cell by index in the footer row
