After doing a postback, can I have the focus go to the middle of the page or more specifically to a label?

jQuery $(document).ready() and ASP.NET Ajax asynchronous postback

Many call it the ASP.NET jQuery postback problem, but using the technique below should make it no problem anymore. $(document).ready() isn't called after an asynchronous postback. What this means? You lose the functionality that should be executed within $(document).ready() after an UpdatePanel rendered its contents after an asynchronous postback.

jQuery live() and ASP.NET Ajax asynchronous postback

The issue is that normally $(document).ready() is called when the DOM is ready to be manipulated. But this doens't happen after an ASP.NET Ajax asynch postback occurs.

This means that the initial jQuery bindings won't be automatically available after the asynchronous postback is over. I underline "automatically" here because my last post describes more possibilities, how this issue can be worked around.

Maintain HTML Radio Button Selection Inside GridView After Postback

Long time ago I wrote an article about getting the value of the selected RadioButtons inside the GridView control. The code did not addresssed the postback issue which means that the selected radio button was cleared after the postback occurs.

Dynamically load user control without postback


Hi all,

I need urgent help. (c#coding)

In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.

While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.

Is there any way to load controls without postback? I Really need help as soon as possible.

Here is my code:

protected void Page_Init(object sender, EventArgs e)
        if (Session["control"] != null)
            string c = Session["control"].ToString();
            if (c == "1")
                iuc = (IlkogretimUC)LoadControl("~/Controls/Ilkogretim.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "2")
                luc = (LiseUC)LoadControl("~/Controls/LiseUC.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "3")
                youc = (YuksekokulUC)LoadControl("~/Controls/Yuksekokul.ascx");

Change part of a page without full postback


I have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript, but I don't know how and would appreciate some help. Thanks!

How to CATCH "Invalid postback or callback argument" exception?



How can I catch this exception? I do not want it to stop my page execution. Can/Should I do that?

(Imperfect) Solution to TreeView Postback / Client-Side Node Selection Issue


I've seen this question posted on all corners of the web... "How do I disable "AutoPostBack" on the ASP.NET 2.0 TreeView control?!"  Unfortunately, most of the answers either don't work, miss the point (don't work right), or boil down to "You can't do it."  I happen to know that this behavior worked perfectly in the IEWebControls TreeView that Microsoft released as an add-on prior to ASP.NET 2.0, however.  So I set out to find a solution for the ASP.NET 2.0 TreeView issue.

In a nutshell, the behavior that I and others are looking for is to have a TreeView rendered in a page that allows the user to expand, contract, and select nodes within the TreeView without causing a PostBack to the server.  This implies two things: (1) the most recently-selected node should be recorded as the currently-selected node [i.e., at PostBack time, the most-recently selected node is actually represented as the SelectedNode]; and (2) the selected node should exhibit the SelectedNodeStyle as specified in the TreeView declaration.

It appears that the TreeView engineers saw only two possible outcomes from selecting a leaf node in a tree: (1) immediately posting back to the server, or (2) immediately navigating to another web page.  They apparently did not consider option (3) just allowing selection in-place on the client, while waiting for a click on so

GridViewRow change after postback


 I add gridview row dynamically like that; After page postback some gridrow change and not visible. How can solve ? thanks.

protected void grv_RowDataBound(object sender, GridViewRowEventArgs e)

            string kategoriAd = drv["NAME"].ToString();

            if (!kategoriAd.Equals(m_kategoriAd))
                GridViewRow row = new GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal);
                TableHeaderCell cell = new TableHeaderCell();
                // TableCell cell = new TableCell();

Display a nested child ListView on PostBack while using DataPager on parent ListView


Hello ASP.NET community,

I am having trouble finding how to solve the following issue :

I am using nested listviews to display Sales and Sales details.

The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :

ASPX Markup Code :

<asp:listview id="lvSales" runat="server" onitemdatabound="lvSales_ItemDataBound">
<table cellspacing="0" border="1" width="250" style="border-collapse:collapse;">
<tr runat="server" id="headerRow">
<th scope="col" style="width:30px;"></th>
<th scope="col">SaleNumber</th>
<tr id="itemPlaceHolder" runat="server" enableviewstate="true"/>
<tr id="row" runat="server">
<td style="text-align:center;"><asp:button id="btnShowHideDetails" runat="server" oncommand=&qu

Suppress postback on ImageButton


I have the following JavaScript defined for the OnClientClick event of an ImageButton:

var _oHasChanged = $get(_chkHasChanged); if (_oHasChanged && _oHasChanged.checked) { alert('De gewijzigde gegevens moeten worden opgeslagen alvorens deze actie kan worden uitgevoerd.'); return false; }

As you can see, I have "return false;" after the alert, because I don't want a postback in that situation.

This is working just fine in Firefox, but Internet Explorer seems to ignore the "return false;" bit and posts back to the server anyway.

What am I missing here?

Firing postback from Repeater row click.


Hi all,

I have a repeater which contains a hidden link button that fires when I click a row in my repeater.

Here is the markup for my repeater:

<div id="divResults" style="height: 290px; overflow-y: auto;">
<asp:Label ID="lblNote" runat="server" Text="Note: select a row to edit."></asp:Label>
<asp:Repeater ID="rptLocations" runat="server" onitemdatabound="rptLocations_ItemDataBound">
    <table width="100%" cellspacing="1" cellpadding="3">
     <th style="width:30%;">SEAT</th>
     <th style="width:65%;">Establishment</th>
     <th style="width:5%;"></th>
 <tr id="trResults" runat="server">

UpdatePanel - UpdateProgress only displays on initial postback



I'm having a somewhat odd issue, I'll do my best to explain it.

In a nutshell I have an UpdatePanel with an UpdateProgress item, first postback checks for warnings, if there are any they will be be displayed to the user as a JavaScript 'confirm' box. If the user clicks OK the next postback occurs to commit the change.

The UpdateProgress loading notification appears on the first postback but not on the second, even though both of them function correctly.  The buttons that trigger both postbacks are async postback triggers in the update panel, and both are inside the ContentTemplate.

It's not a huge problem, but it causes some confusion, has anybody ever seen this issue before?


Updating a label twice during a postback


I am updating a label as part of an imagelabel click using an update panel as this process can take some time. What I would like to do is update the label at the start of the processing so that when the user clicks it says 'procsessing...' and when it finishes processing it says 'done'

I thought I would be able to do this by calling the following:

btnClockIn.Attributes.Add("onClick", "return clearstatus();")

and then using the foolowing script on my webpage:

function clearstatus() {
    form1.lblStatus.value = "";
    document.getElementById("lblStatus").innerHTML = "change in text or whatever";
    return true;

But this doesn't seem to do anything (I have tried setting .value as well)

Is there some way that I can update a label more than once during postback?


Update Panel only doing full postback

I have a page with a TabContainer with 3 tabs.  Within each tab, I have an UpdatePanel.  One of my UpdatePanel's update mode is set to "conditional" and I've added an asyncpostbacktrigger with the controlId="btnClearEmail1" and the eventname="Click".  When I run the page and click the button assigned to the asyncpostback trigger, the page will do a full postback.  Am I forgetting something?  How can I get it to just refresh what is inside the UpdatePanel?  <asp:tabcontainer id="ajaxTabContainer" runat="server"> <asp:tabpanel id="ajaxTabCustomerInfo" runat="server" headertext="Customer Information" visible="true"> <contenttemplate> ... [clipped for brevity] </contenttemplate> </asp:tabpanel> <asp:tabpanel id="ajaxTabSiteBranding" runat="server" headertext="Custom Site Branding"> <contenttemplate> <asp:updatepanel id="UpdatePanel2" runat="server"> <contenttemplate> ... [clipped for brevity] </contenttemplate> </asp:updatepanel> </contenttemplate> </asp:tabpanel> <asp:tabpanel id="ajaxTabEmails" runat="server" headertext="E-mail Notifications"> <contenttemplate> <div> <asp:panel
