This UpdatePanel is contained by an UserControl. When the LinkButton is pressed arow should be added in another GridView. When an user is logged in this control is working well.
The problems appears when an user is not logged in and try to push that button. No event triggers.
Someone suggested me to give a permission for accessing this control in web.config. That didn't work.
Anyone has another idea?

<div style="text-align:left;">
<img id="img" style="float:right;" src='<%# Eval("Picture") %>'
height="75" runat="server" alt="Picture" />
<b>
<%# Eval("Name") %>
</b>
<br />
<br />
Price: <b><%# Eval("Price") %></b>
<br />
<br />
<br />
</div>
<hr />
<div style="text-align:left;">
<b>Description</b>
</div>
<div style="width:300px;">
<%# Eval("Description") %>
</div>
<br />
<asp:LinkButton Enabled="true" runat="server" Text="Add" CommandName="Select" ID="cmdAdd" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
I solved the problem in a tricky way.
I deleted the LinkButton and before TemplateField I put a ButtonField and all is working fine.
Now the code looks like:
<Columns>
<asp:ButtonField Text="Add" CommandName="Select" />
<asp:TemplateField>
......
</asp:TemplateField>
</Columns>
Still I'm not understanding why the control had that behavior.
Don't forget to give the webresource.axd enough rights in the web.config?

I Have an ASP web page with a GridView and need to Edit, Delete, and Insert records. I have gotten the edit and delete functions running but am having a problem with the Insert portion.
When I attempt to save the new record all of the data fields are empty. I know the C# code is reading the text values on the row because I have a dropdown and a checkbox on the rows that are getting their values, but it is the default values and not the ones I selected for the insert.
Pretty sure it is a post back problem since I have noticed I don't have an UpdatePanel on my web page. I have tried to wrap the gridview within an UpdatePanel but when I do that I get the error stating GridView is not a known element. I have tried wrapping the gridview in a Div and then wrapping the div in the update panel. But then I get the Error div cannot be nested in the update panel.
So I think I need to include the update panel on the Master page but cannot get it to compile when I move it over there. I have tried putting the panel in various location on the Master Page. Can someone point me in the right direction on this?
I have been asked to provide more code here is the ASPX page that has the gridview

Master pages are for styling. You should not be touching them in this case.
Add the MasterPageFile attribute to the Page element in your .aspx markup file that contains your GridView.
<%# Page MasterPageFile="~/YOUR_MASTER_PAGE_FILE" ... %>
Note the id of the asp:ContentPlaceHolder in your Master page.
<asp:ContentPlaceHolder id="PageContent" runat="server"/>
Wrap the content of your new .aspx page in a asp:Content element which has an attribute asp:ContentPlaceHolderID equal to the ID of the asp:ContentPlaceHolder element in your master page file.
<asp:Content ID="mainPlaceHolder" ContentPlaceHolderID="PageContent" runat="server">
Here is an example for inserting records using a GridView
Please post the relevant markup and back-end code for you GridView and insert logic. I can't offer any more assistance based on the information provided.
HoverMenuExtender only works after postback in gridview. Weird behavior.

Problem is your ClientIDMode property on Textboxes
ClientIDMode="Static"
You need to remove abvoe attribute from your GridView code, because if you use it, all your TextBox controls will have the same ID, "txtCheckoutDt_LodgingNLiving" for this particular control on it calender extender is set. The CalendarExtender controls will find the first value (which is on the first row) and will be all mapped to it.
If you want to refine the patterns of your control ID assignment, here's more about the topic.
I have a UserControl which is a nested GridView (facebook like wall), i want to load posts on scrolling down. I am following this article..
CLICK ME
The problem is that this method is using the first column's last row to get the last productid
something like this
var lastProductId = $("#GridViewUserScraps tr:last").children("td:first").html();
But in my case i am not displaying any id in any of the columns of the UserControl's GridView though i have a ScrapId column(primary key) in database. How can i load Posts on scrolling down? how can i make it work?
My UserControl:

I have an UpdatePanel and a GridView within it. I have a problem with paging: when I press Next button, grdUsers_PageIndexChanging() is not called, so the page stays 1, and if previously I changed selection in ddlPageSize, now it goes back to the initial selection.
Also, if I am on the first page, the Previous button is not disabled, and pressing it causes Out Of Range error.
What am I doing wrong?
Thanks.

Agreed, I tested the code, and grdUsers_PageIndexChanging() is called on mine.
Dear Friend
their is in build paging in the gridview if you want your own paging style then you have to implement your own paging through PageDataSource Class.
Click to view code
this link provide you how to implement the paging in the Datalist and Repeater through same way you will implement the paging in grid view .
Then no pageindex change event will fired in the gridview.
I don't think you are doing anything wrong; it may not actually fire the PageIndexChanged event, it probably fires the RowCommand event. Attach to the ItemCommand event and that will receive the event.
HTH.
