Button not preserving ID after partial postback in updatepanel?

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :ASP.Net

I've created a dynamic button from another control outside of the update Panel.  The button is given an ID and such.  When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value. 

The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button.  Because I ID'd teh button as: ButtonRow_0Col0.  But the actual ID is null.  However, when traversing through page.request.form, the allkeys shows that ID with no problem.

So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??

textbox not writable after partial postback of updatepanel

hi, i got a strange problem. my project was ok before implimenting ajax. i have just implimented ajax in one page only with Tabcontainer and updatepanels only nothing else. almost all controls are devided into different Tabs with respective update panels. mostly it is working ok. but the problem is : 1.   in some controls i am not able to write anything even the control is "Enabled=True" and focus is on the same control after partial postback. 2.   and as soon as i press Tab control goes to Address bar. 3.   some time tab key is also not working.Why ? here some code :<td style="width: 57684px; text-align: left">                                                Inception Date (dd-mm-yyyy)</td>                                            <td style="width: 604px; text-align: left">              &n

Button forces postback in updatepanel inside Popup

Full PostBack in IE and Partial PostBack in other browsers using an UpdatePanel


I have an UpdatePanel that works fine and always updates the content when the RadioButtonList selected index is changed. What I want to do, is trigger full page postback in IE, but allow the UpdatePanel to do partial page postback in all other browsers.

Here's my markup (I removed the internals of the UpdatePanel since they are not relavent):

<asp:UpdatePanel ID="uplPodcasts" ChildrenAsTriggers="false" UpdateMode="Conditional" runat="server">
                    <div id="plPodcastsControls">
                	    <span style="font-weight: bold; line-height: 26px;">Display Mode:  </span>
                        <asp:RadioButtonList ID="rblPodcastsDisplay" CssClass="rblPodcastsDisplay" 

                            <asp:ListItem Selected="true" Text="Table" Value="table" />
                            <asp:ListItem Text="Grid" Value="grid" />

How do you save state of a toggle button after partial postback?


lets say you  have the toggle buttons from this page: http://www.filamentgroup.com/examples/buttonFrameworkCSS/

and you put it in a UpdatePanel AJAX...  so lets say on a partialpostback.. when you re-create teh controls on server-side, the state of whether or not those buttons were pushed is long-lost and gone.. so how then how do you remember those states?

Can I save each button state into viewstate or session state?  regenerate each button then call the javascript function to change its color-state depending on the session state variable?


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.

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?

UpdatePanel postback and resulting ViewState

Hi everyone,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?

Problem with custom onBeginRequest-Handler on client-side when partial postback is triggered from ja

Hi, I have a Modal Dialog with a Ribbon, which starts a long running serverside operation. To inform the user about the progress, I implemented Dino Espositos "Progress Monitor Framework", which worked perfectly (after some work) - at least when I trigger the partial postback from a control inside the UpdatePanel used for displaying the progress. In this approach custom onBeginRequest and onEndRequest-Handlers are used to start and stop displaying the current status of the serverside operation. When I start the operation from a Button on the ribbon by doing "something" with the mentioned control via javascript the serverside operation is started, but my onBeginRequestHandler ist not called and the progress monitor is not "switched on" on the client. Here is what I´m doing in my javascript :  function pageLoad() { progressManager = new VCSharePoint.MultiEdit.Progress(); // Remove existing handlers Sys.WebForms.PageRequestManager.getInstance().remove_beginRequest(onBeginRequest); Sys.WebForms.PageRequestManager.getInstance().remove_endRequest(onEndRequest); // Register handlers for UpdatePanel client events Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(onBeginRequest); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(onEndRequest); } // onBeginRequest() // Called w
