AJAX :: Label Not Getting Refreshed When Working With UpdatePanel
Aug 23, 2012
I have an extra asp.net label to show success or error message after the add, update or delete a row,Â but using the BlockUI, I am unable to do it, cause the label is somehow not refresh even if i put it under the BlockUI.
I am using two Updatepanels in ASP.NET AJAX and as soon as there is some event in first updatepanel, it will get refreshed at that time I want my second Updatepanel getting refreshed too. How can I do that ?
I'm writing a small photo album application and having some problem of refreshing the original images in the updatepanel. I have two updatepanels, one on the left contains a gridview to display image thumbs, and the other in the right contains an image control. When click on the thumb on the left, the file name of the image on the right will be inserted using the CommandArgument value. However, when I clicked the thumb, nothing happened. Instead of refreshing an image, I put a label and it worked fine. The following is my aspx side code and code behind.
I have an asp UpdatePanel, an asp panel, an asp timer, and an asp label on my web page, as you know the whole idea of updatepanel is trying to implementing partial page rendering mechanisem, however, it is not the case in my scenario, here is the code:
and on the pageload event, i assign:
strangely, the labl1 does update the time without causing the whole page post back, but the panel does cause the whole page refreshed, and the asp panel contains asp buttons and those buttons are generated dynamically by code behand c# file, am i missing sth here or the nature of asp:panel will cause the whole page post back?
I have a web application project, in which i have 2 projects one is for my UI and other for dealing with database. In UI i have a page on which i have used update panel and script manager, the usual procedure, but surprisingly update panel is not working my page is getting refreshed.
I either don't understand or I'm not using AJAX right. I'm running a long report. I'd like to have a label to show the user that the "Report Running", then, that the report has finished. But, when the user runs another report, I'd like to have the label that shows "Report Finished!" to clear so that you don't have "Report Running!" and "Report Finished!" on the screen at the same time. But, the label will not clear???? I get both lables showing. What am I doing wrong?
I have a user control embedded in an UpdatePanel. I'm trying to display a message on the parent page which contains the UpdatePanel when I complete some work in the code-behind of the usercontrol. It appears that due to the partial postback the event delegates that the original developer used to update the labels with messages don't get updated from calls within the user control. The call to the event delegate is executing and I can trace the execution including assigning the text to the label, but when the page is updated the message is not displayed.
I tried moving the labels inside the user control and therefore within the UpdatePanel and setting up event delegates in the user control page_load but that has the exact same effect.
I have some code that I am working on that uses an UpdatePanel and some dynamically created buttons to perform functions. The problem is that the dynamically created buttons aren't working the same as my test static button, which is behaving exactly as it should be.
So I was wondering if someone would be willing to simply post an example (in VB.NET or C# please) of the following:
An UpdatePanel has a Label and a Placeholder inside of it
The Placeholder has a dynamic button added to it
Clicking on this button will make the Label say "Hi" without performing a full page postback.
If I can just get that much to work, I am sure that the rest of the code will be fine. I just can't seem to get my dynamic buttons to act like my static ones do in an UpdatePanel.
I have an UpdatePanel with a button and a label. Inside the button click event I call a web service which returns a string. I then want to append that to the label. Simple! Except that it doesn't work. I can change the label to a value I set inside the click event but when I try to add the web service string it doesn't work.
I have been trying to override the PreRender event, to use a ViewState, to set EnableViewState on the Label to be false. Nothing. Works. At All. If I set a break point inside the OnPreRender override I can see that lbl1.Text is being set to the value that I want (i.e. the value from the web service) but it doesn't appear on the browser.
I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.
In my application, I am using different user control for different tasks. I used an update panel to load user controls with ajax. It is working fine. I am using some other update panels inside the user controls. My problem is, the inner update panel(UpdatePanel placed inside the user control) is not working properly.
I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this. Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.
I am building a website using ASP.net ajax. there are 3 <asp:panel> controls in the page and each contains a number of dynamic linkbuttons. these panels are contained in a <asp:updatepanel> control the page_load event fills out the first panel with linkbuttons and assigns cooresponding commandName commandArgument for them, that works. then the first panel's linkbuttons triggers the command and fill out the second panel with linkbuttons, that works too. then the seond panel's linkbuttons are supposed to fill out the third panel with linkbuttons, but that doesn't work anymore, and it seems like doing the page_load event again and filling out the first panel and the second panel's linkbuttons disppear, just like the first time the page is loaded.
my code is very simple. I have one updatepanel, it has one lable and one dropdownlist. everytime, dropdownlist index changed. Label shows selected value. if you select any options besides the first one, it works. if you go back to the first option, then event will not get fired. spending hrs searching on google, couldn't find anything useful.
I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?
I have one button and one textbox inside a updatepanel. On button click I am adding an alert script. But when I use the ViewSource by right clicking on the page, then the alert script is not generated.
But if I remove the the UpdatePanel then the script is generated and the alert message is displayed. What should I do to register the script when using updatepanel.
I have a ReportViewer with drillthrough function report and it takes 3 mins to run the report on buttonclick.So I have enclosed ReportViewer with AJAX update panel and give a wait.gif ProgressTemplate. After this change onbuttonclick now the wait gif appears and then the report displayed as desired after 3 mins. However, now the drilldown function of the report is not working anymore and view error it says "ClientReportxaxsaacscdcsdci678686 is not defined.
I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.
I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..
