I have a gridview which is inside the update panel. Also I have setup a multipe filters which works fine. After the search I get the correct returns and page numbers but as soon I switch the pages, it loses its state and lists all the page numbers.
[Code]....
Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
UpdatePanel2.Update();
}
Why paging causes gridview to stop working correctly? What can I do?
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:

Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
View 3 RepliesI followed your topic to select all rows with checkbox in gridview header and it is verygoodThis is code :
<script type="text/javascript"> function CheckAll(objRef) {
var grid = document.getElementById("<%=Grd_Data.ClientID%>");
var headerCheckBox = document.getElementById("ChkAll");
var inputs = grid.getElementsByTagName("input"); for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "checkbox") { if (objRef.checked) { inputs[i].checked = true;
} else { inputs[i].checked = false; } } } }</script>
But i noticed that when i deselect a row in gridview the checkbox in header is still checked.How can i fix this problem that when i deselect one row from gridview the checkbox in grid header change to be unchecked ?
I have Gridview in UpdatePanal but their is problem with template fieldÂ
<asp:TemplateField HeaderText="EDIT">
<ItemTemplate>
<asp:LinkButton ID="lnkEdit" runat="server" ToolTip="Edit Unit" OnClick="lnkEdit_Click"

and link button click event isÂ
protected void lnkEdit_Click(object sender, EventArgs e)
{
GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
ScriptManager sm = (ScriptManager)Page.Master.FindControl("smanager");
sm.RegisterPostBackControl(clickedRow);
lblUnitID.Text = clickedRow.Cells[0].Text;
txtUnitName.Text = clickedRow.Cells[1].Text;
txtDecimal.Text = clickedRow.Cells[2].Text;
btnUnit.Text = "Update";
}
but text box value is not set but when we do it in  PostBackTrigger is work.
can we do this AsyncPostBackTrigger.
I tryed to put a nested Gridviews (parent-child) in an UpdatePanel, but it didn 't work as I want. Firstly the code of the Gridview (its from the example reffering to this [URL] .....)
<form id="form1" runat="server">
<asp:ScriptManager ID="scriptMgr" runat="server" EnablePartialRendering="true" />
<asp:UpdatePanel ID="updatePnl" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="False" CssClass="Grid"
DataKeyNames="CustomerID" onrowcommand="RowCommand1">
[CODE]...
 in the scriptManager, no exception will be shown, but on RowCommand a complete Postback is done.
I have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.
View 9 RepliesI have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.
Would it be possible to do Sorting and Paging in a DataGrid, My dataGrid is place inside an asp:wizard which is inside an Update Panel.

I am new to Ajax. I have problem in paging for gridview which is in a update panel.I set the update panel update mode to conditional. The 2nd page records are not display after I click the 2nd page.for ref:
scriptmanager mode=release,enable page method=true.
updatepanel:always
I have a simple form containing a gridview that displays some records. Everything works fine but I was hoping to wrap the grid view inside an updatepanle to prevent a full postback (flickering) when paging.
It doesn't seem to matter what I try, paging always causes a full postback which causes the page to flicker. What am I doing wrong?
Here's my markup:

And here's my aspx code:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>
I have an UpdatePanel which has inside a detailsview, this DetailsView has a TemplateColumn with a UserControl.The UserControl has a NumericUpDownExtender and when the user clicks on an arrow or changes the value of the textbox a server event is raised (this is made by me, not default behaviour). I do this by using the add_currentChanged of the extender (in the javascript pageLoad function, and remove_currentChanged (in the javascript pageUnload function) and implementing the interface ICallbackEventHandler in the UserControl. My problem is that when the user click on the arrow, the event is raised twice and the correct value is overwritten.
View 3 RepliesI have a datalist that has an imagebutton, I want the updatepanel to trigger each click of the imagebutton of each result. How Can I do that?
View 2 RepliesI hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

I have a GridView that uses custom paging inside an UpdatePanel (so that the paging and sorting of the gridview don't cause postback). The sorting works fine, but the paging doesn't. The PageIndexChanging event is never called. This is the aspx code:
<asp:UpdatePanel runat="server" ID="upSearchResults" ChildrenAsTriggers="true" UpdateMode="Always">
<ContentTemplate>
<asp:GridView ID="gvSearchResults" runat="server" AllowSorting="true" AutoGenerateColumns="false" AllowPaging="true" PageSize="10" OnDataBound="gvSearchResults_DataBound"
OnRowDataBound ="gvSearchResults_RowDataBound" OnSorting="gvSearchResults_Sorting" OnPageIndexChanging="gvSearchResults_PageIndexChanging" Width="100%" EnableSortingAndPagingCallbacks="false">
<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:HyperLink ID="lnkAdd" runat="server">Add</asp:HyperLink>
<asp:HiddenField ID="hfPersonId" runat="server" Value='<%# Eval("Id") %>'/>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="First Name" DataField="FirstName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="FirstName" />
<asp:BoundField HeaderText="Last Name" DataField="LastName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="LastName" />
<asp:TemplateField HeaderText="Phone Number" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" >
<ItemTemplate>
<asp:Label ID="lblPhone" runat="server" Text="" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerTemplate>
<table width="100%" class="pager">
<tr>
<td>
</td>
</tr>
</table>
</PagerTemplate>
</asp:GridView>
<div class="btnContainer">
<div class="btn btn-height_small btn-style_dominant">
<asp:LinkButton ID="lbtNewRecord" runat="server" OnClick="lbtNewRecord_Click"><span>Create New Record</span></asp:LinkButton>
</div>
<div class="btn btn-height_small btn-style_subtle">
<a onclick="openParticipantModal();"><span>Cancel</span></a>
</div>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="PageIndexChanging" />
<asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="Sorting" />
</Triggers>
</asp:UpdatePanel>
In the code behind I have a SetPaging method that is called on the GridView OnDataBound event:
private void SetPaging(GridView gv)
{
GridViewRow row = gv.BottomPagerRow;
var place = row.Cells[0];
var first = new LinkButton();
first.CommandName = "Page";
first.CommandArgument = "First";
first.Text = "First";
first.ToolTip = "First Page";
if (place != null) place.Controls.Add(first);
var lbl = new Label();
lbl.Text = " ";
if (place != null) place.Controls.Add(lbl);
var prev = new LinkButton();
prev.CommandName = "Page";
prev.CommandArgument = "Prev";
prev.Text = "Prev";
prev.ToolTip = "Previous Page";
if (place != null) place.Controls.Add(prev);
var lbl2 = new Label();
lbl2.Text = " ";
if (place != null) place.Controls.Add(lbl2);
for (int i = 1; i <= gv.PageCount; i++)
{
var btn = new LinkButton();
btn.CommandName = "Page";
btn.CommandArgument = i.ToString();
if (i == gv.PageIndex + 1)
{
btn.BackColor = Color.Gray;
}
btn.Text = i.ToString();
btn.ToolTip = "Page " + i.ToString();
if (place != null) place.Controls.Add(btn);
var lbl3 = new Label();
lbl3.Text = " ";
if (place != null) place.Controls.Add(lbl3);
}
var next = new LinkButton();
next.CommandName = "Page";
next.CommandArgument = "Next";
next.Text = "Next";
next.ToolTip = "Next Page";
if (place != null) place.Controls.Add(next);
var lbl4 = new Label();
lbl4.Text = " ";
if (place != null) place.Controls.Add(lbl4);
var last = new LinkButton();
last.CommandName = "Page";
last.CommandArgument = "Last";
last.Text = "Last";
last.ToolTip = "Last Page";
if (place != null) place.Controls.Add(last);
var lbl5 = new Label();
lbl5.Text = " ";
if (place != null) place.Controls.Add(lbl5);
}
The paging works if I don't use custom paging, but I really need to use the custom paging. I can't figure out why the PageIndexChanging event isn't fired when I'm using the custom paging.
