I'm having a somewhat odd issue, I'll do my best to explain it.
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?
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">
<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" />
I have a page with about a dozen update panels. This morning I updated one to work with a Timer and delay the loading of content for speed reasons. Now this web part wants to updated everytime a postback is submitted on another web part.
I feel I'm missing something simple but can't put my finger on it. I have included my CreateChildControls() subroutine. I have made sure the updatepanels had IDs and set the ChildrenAsTriggers property to true but neither of these
seem to help. The webpart updates by going just going blank.
public class myClasses : WebPart
private UpdatePanel _masterPanel;
private UpdatePanel _upDatePanel;
private String _errorMessage = "";
private String _username;
private Timer _loadTimer = new Timer();
private Image _loadingImage = new Image();
protected override void CreateChildControls()
Is there a way for me to call a js function that I have registered the first time after a post back of an update panel?
In the first initial request to the page I register a script block and it works fine.
BUt it doesnt not fire or execute when the updatepanel does a post back.
I did a simple test and just did and page.ClientScript.reg...('alert("test"))
the code works so dont worry about my example syntax. I t just does an alert. The alert is executed once when the page was first requested. but not after a post back. any ideas?
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??
I'm running some server code that generates a bunch of status lines to the user. However, even though this is on an updatepanel, nothing happens before the function completes. Not really a surprise. However, I would like to be able to somehow update this field so that the user can see something actually happning while they wait.
Anyone know of a good way to do this?
I have a web page that contains an updatepanel, inside this there is a button with script in OnClick event.
While clicking the button am setting a text in the label control which is in the site.master
My problem is that label is not showing the text am setting (or postback for master control is not working).
Without updatepanel label is coming.
Thanks in advance
It worked on one of my old pages. I change the web.config, renamed all the <asp.
On some aspx page it doesn't recognize the updatepanel. It only does on one page. If I create a new aspx page with a different name - then it works.
Should I just create a new web project ajax - then copy all my code into there? Or is there a way to get those old pages to recognize the new ajax controls?
I am displaying large amount of data in gridview,the gridview placed within updatepanel,every 1sec i am refreshing updatepanel using ajax timer.my problem is while displaying large data the cpu performance is low,pls give idea to increase cpu performance..
