Here is what I am doing. I create two buttons in a header row of a gridview that i created. The buttons are +page and -page. When -page is hit I remove the paging and all the data goes down the page and -page disappears and +page is there.
Here comes my issue When I hit +page I must be double postbacking because one row of my data disappears. I will provide the code below. What can i do to fix this??
Dim bttnrempag As New Button
bttnrempag.ID = "bttnrempag"
bttnrempag.Text = " Paging"
bttnrempag.CssClass = "bttnMinEG"
bttnrempag.ValidationGroup = "alone"
bttnrempag.Attributes.Add("onclick", "return Paging('1')")
Dim bttnallowpag As New Button
bttnallowpag.ID = "bttnallowpag"
bttnallowpag.Text = " Paging"
bttnallowpag.ValidationGroup = "alone"
bttnallowpag.CssClass = "bttnAddEG"
bttnallowpag.Attributes.Add("onclick", "return Paging('0')")
———————How the buttons are added——————————————
Dim row As New GridViewRow(-1, -1, DataControlRowType.Separator, DataControlRowState.Normal)
row.Cells.Add(cell)
cell.Controls.Add(bttnrempag) '36
cell.Controls.Add(bttnallowpag)
—————————————————————————————-
function Paging(remove) {
var gridView = $get('<%=Gridview1.ClientID %>');
var txt2 = $get('<%=TextBox2.ClientID %>');
if (remove == '1') {
txt2.value = '1';
__doPostBack('<%=UpdatePanel1.ClientID %>', '');
return false;
}
else {
txt2.value = '0';
__doPostBack('<%=UpdatePanel1.ClientID %>', '');
return false;
}

</asp:UpdatePanel>
So as you can see, when one or the other is hit I set a textbox to some value then i do a partial postback to my Gridview which is in that Updatepanel.
Best Solution
I've found a nice solution that works great. It does append it's own handler, but I guess that can be fixed too.
