Menu
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;
}

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.

I suspect it's because you called the "__doPostBack" method. The buttons' normal default click behaviour will perform the Async postback, you probably made it perform another time. Try removing it and see how it goes.

Can you try to put the Click Attribute on the buttons in RowDataBound event declaration??
