AJAX :: Chart Inside UpdatePanel And RadioButton PostBack?
Jan 27, 2011
My problem is very simple: I have a chart inside an UpdatePanel (I'm using AJAX) and 2 RadioButton in which AutoPostBack=true.When I click on my "generate chart" Button, the chart is well painted on the page but the AutoPostBack of my 2 RadioButtons seems to stop firing. That is to say, after painting, If I click on my RadioButton the postback doesen't works!I need to set some kind of trigger related to the chart?

Explaination in detail I have a tree view control on left of my page and AjaxToolkit:TabContainer on the right,consisting of 9 tabs in it (I have developed individual controls and added to the tab panels). On selecting a value from the tree view control the I am refreshing the values inside all the tab panels. There is a method reload written on all the controls which are called on tree view click which sets the value of the selected tree item in properties in all the controls and also refreshs them. Its a big performance issue for sure which i need to improve on but that would come later.
My problem
1. In the Main tab (ascx control) consists of asp:chart control which I am populating and it also consists of 2 buttons in which ModalPopupExtender would open up another 2 controls on button click within this control. Now on the tree view click I am calling
the reload of Main Tab which internally called the reload function of these 2 controls also
On Tree view click
Maintab.reload
{
ModalPopupExtender1.reload
ModalPopupExtender2.reload
}
Secondtab.reload
Thirdtab.reload
If I populate the asp.chartcontrol without reloading the ModalPopupExtender1.reload ModalPopupExtender2.reload it works great but when I call both ModalPopupExtender1.reload
ModalPopupExtender2.reload it shows up and goes away.
Any thing i am missing on ? How to make chart control stay on the page and not vanish. I tried making it visible again. The main page contains a chart control which comes and goes away and does not stay only if i comment out the reloading of these usercontrols it stays visible with values on the main page else goes away.
2.Performance problem- I am not sure how to lazy load the content inside the tab panels so that controls should have the selected item for tree view click and can populate thereon.
3. This is how I call my user controls to reload on the treeview click from within the main page.
PEGeneralInfoPortfolioProfiler1.PortfolioCode = strPortfolioCode;
PEGeneralInfoPortfolioProfiler1.ReloadControl(1);

When I want to optimize my tab container for network traffic, I faced a rare problem.
When first time the page is requested the content in the first panel is visible. the other panel content are invisible. When user switches the tab i am setting the panel visible and update the updatepanel. this works fine after i have put the tab container inside a update panel and set the update mode conditional and children as trigger as false. But when i include the tab container inside an update panel and change the tab in the browser, i see two postback from the browser in firebug net traffic window. THe first postback status is displayed as aborted. Eventhough the functionality is working correct.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

I am trying to add some JQuery animations before and after every postback request is made inside my UpdatePanel. What I have so far is something like this:
<script type="text/javascript">
$(document).ready(function () {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
function EndRequestHandler(sender, args) {
if (args.get_error() == undefined) {
// End Request (1)
}
}
function BeginRequestHandler(sender, args) {
// Start Request (2)
}
$('.MyButtons').live('click', function () {
// Before request (3)
});
});
</script>
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:Button runat="server" CssClass="MyButtons"/>
</ContentTemplate>
</asp:UpdatePanel>
Let say I want to put some animation code at (3) that will be executed and then proceed with BeginRequestHandler function. How should I do that? Because right now the whole process executes 3,2,1 and I dn't know how to add that delay between steps 3 and 2. In other words I want to execute step 2 manually at step 3. Don't really want to use hidden buttons to do that.

I have a div with "id=ShowDetails". In my javascript I have this:
$(document).ready(function () {
UIactions();
});
function UIactions () {
$('#ShowDetails').click(function () {
alert("bingo");
}
});
The div is inside the update panel that gets posted back. When the page loads, if I click the div, I get the bingo but after the postback, I don't.

I have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>
I think that is because the link button is rendered using a script and that script is not run after the post back.

I found this solution to force full postbacks from within an UpdatePanel
<Triggers>
<asp:PostBackTrigger ControlID="controlID" />
</Triggers>
but my control is actually inside an ItemTemplate nested in a GridView. Therefore when my page loads, it doesn't find that control.
How can I force a full postback from my control (an asp:LinkButton) from within my GridView?

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
The source code:
<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

I started using the awesome chart controls with my asp.net apps recently and so far they've been nothing short of breath taking. Right now I have a weird problem, on the first load of my page, the chart control appears correctly and the tooltip is correct, however, when I update it with new data, the chart displays correctly, but the tooltips are for the previous set of data.
I hope this makes sense. The first time I load the chart, the pie chart segments and tooltips are correct, after a partial postback (to get the new data), the pie chart segments are correct but the tooltips are for the previous data set.
Basically once the tooltips are set the first time, they can't be updated after that without a full page postback.
Here's how I set the tooltip:
[Code]....
Anyone else noticed this behaviour and have a work around?
Currently my only workaround is to check for a partial postback and not render the tooltip, which I'd rather not do as the tooltip display actual statistical data as opposed to the pie itself (which uses percentages).

I'm trying to implement Google Interactive chart inside an updatepanel.
The regular Google Charts do work (I think because there I'm just calling an URL).
But now I want the interactive chart inside an updatepanel within a tabcontainer etc. But now the request to Google is made, resulting in an infinitely loading white page to Google.
How can I get this to work?

I'm reading about the UpdatePanel and how it interacts with controls inside & outside of it.
My understanding is that the usual ASP.Net pipeline takes place when posting from within an UpdatePanel-- Page load etc all fire off as normal-- except when the prerendering stage is reached. In that case the ScriptManager does a final check and only renders those controls within the UpdatePanel and skips the rest. That's my understanding at least.
Sounds good, but for argument's sake let's say I have a TextBox located outside an UpdatePanel. If a postback occurs from within that panel, the TextBox's properties can still be set in the page load method, but those changes will not take effect. (normally; it is possible to postback the entire page from an UpdatePanel)
Is that correct? What happens to that TextBox's ViewState in this instance? Is it updated based on what happened to it in the page load method or is that modification tossed out because it wasn't in the UpdatePanel?

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:
