Ajax - Gridview Paging Doesn’t Work Inside UpdatePanel

Jan 26, 2011

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;

Why paging causes gridview to stop working correctly? What can I do?

AJAX :: Gridview.Sort Doesn't Work In UpdatePanel

Dec 5, 2010

I have a GridView in an UpdatePanel and in the code behind I bind to a Datatable and call the GridView's Sort method:

gvUsers.Sort("DateOfBirth", SortDirection.Descending);

However, this doesn't sort the records. I have the Sort event as an asynch trigger for the grid.

AJAX :: Why Doesn't UpdatePanel Work In Asp.net 2.0 Web Site Template

Feb 15, 2010

I'm just getting into AJAX (little late I know) and am walking through some of the tutorials on the ASP.NET/AJAX site. One thing I've noticed is that I cannot get the UpdatePanel to work (meaning, prevent a full postback of the page) in the ASP.NET Web Site template. I can use the EXACT same markup, code, and web.config in the AJAX 1.0-Enabled ASP.NET 2.0 template and everything works as expected.

AJAX :: Fileupload In Updatepanel With Timer Doesn't Work At The Second Time

Jan 23, 2011

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.

I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.

However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

AJAX :: SQLDataSource With Parameters Doesn't Work Inside A ModalPopup?

Jun 8, 2010

although I've searched already, but here is the thing:I have a ModalPopup wich have a Textbox, a Button and a GridView inside. The Gridview is binded to a SQLDatasource object, and the Select query is something like "SELECT field_1, field_2, field_3, field_4 FROM Table_Name WHERE field_1 LIKE '%@Parameter_2%'".This ModalPopup is used (or gonna be used) to search for a field, so the parameters received by the Query is the text inside the Textbox, I've linked thid inside the SQLDataSource Wizard.The problem is that everything works perfectly fine... inside the panel WITHOUT the ModalPopup Extender, but whe I add the Extender the filter function doesn't work.Here is my code:


Notes: I have a ScriptManager inside the MasterPage, so I don't have to insert one in every page. Also I've tested the code in a new page (the one I use for testing), and it works fine, it filters and everything, the problem is when I add a ModalPopup to the panel.

AJAX :: Showing Popup Control Via Javascript Doesn't Work On Explorer 7

Mar 19, 2010

I'm using the following function (found on this forum) to display a popup control from the server-side:

on the server:

ScriptManager.RegisterStartupScript(this, GetType(), "userInfoPopScript",
string.Format("showPopup('{0}', 2);", targetControlClientId)
, true);

on the client:


this works great for explorer 8 , firefox, chrome but on explorer 7 my page just jumps to the left and doesn't show the popup at all.

If I remove the set__parentElementID call, then the popup is displayed but in the wrong position (of course).

AJAX :: AsyncFileUpload Javascript Doesn't Work Within Visible / Invisible Panel

Aug 18, 2010

I have an asyncfileupload control within a panel control. The panel is initially set to visible=false on page load. After a user clicks a button to display the panel contents however, I set the panel to visible and the user can then use the asyncfileupload. The problem however, is it seems much of the javascript associated with the asyncfileupload, does not function properly when the panel containing the upload control is set from invisible to visible. If I set my panel's "visible" property to "true" initially, then it works fine. My javascript error message is as follows:

"Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent."

Basically within my asyncfileupload control, I have the following line:


In this scenario, my "args" variable is always null (when I set my pane's "visible" property to "true" on page load, the args variable DOES contain data. Any idea why switching a panel from visible=false to visible=true, would cause an error like this?

AJAX :: Updating .NET CheckBoxList Inside An UpdatePanel From A Javascript Function?

Sep 29, 2010

I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.

Whenever I click on a checkbox the click event gets triggered and I make a call to

__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.

is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

AJAX :: Javascript Change-state Toggle Button Inside An Updatepanel?

Oct 7, 2010

I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.

The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.

so how can I then, make this performance faster?

AJAX :: UpdatePanel And ListView Inside Another ListView - Work?

May 31, 2010

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?

FileUpload Doesn't Work When Nested In UpdatePanel?

Jan 21, 2010

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<asp:FileUpload onchange="clickTheButton();" ID="FileUpload1" runat="server" />
<asp:AsyncPostBackTrigger ControlID="Button1" />

Button 1 is outside the update panel and the javascript that gets run when a user adds a file in the upload box is this:

function clickTheButton() {
document.getElementById('<%= Button1.ClientID %>').click();

The problem is simple. FileUpload1.HasFile == false. I don't know why this is, but when I put it in the update panel it ceases to work.

I have seen some other threads on this. But none of them answer why this is happening, they just point to things you can download.

EDIT: Really my main reason for wanting to do this is so that I can get a ..Uploading File.. Tag to pop up while the client is uploading to the server and once it has completed, display it in a datalist. I just cant get the UpdateProgress to work.
