May 29, 2010
I am facing a critical condition wherein I have a web page and a User control within it.I need to set the value of two labels in the user control using values collected on the server side.However whatever I do on the server side or client side I do see on the webpage although I can see in the code that it is being set.So Now I am just sending the value from the server side and setting it on the client side.I am sending from server side using,
how to catch update panel's request start (before partial updation request is sent to server) and response receive (before update panel is updated) events.
I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
i am confused about the fact that if partial update of dropdowns is possible through Update Panel ,then why we should use asp.net ajax Cascading drop down extender ,that has made same task bit complex by making callback to web services ? what is difference between using update panel and cascading drop down extender ?
when postback occurs due to update panel's child control then in page load event how can i know that it was dut to update panel ?i.e., i want to differentiate between general postback and postback due to update panel's child control in page load event .How is that possible ?
i have one label out of update panel and one button inside update panel. in button click event i update the label text. when i run the code and click on button then partial postback occur and button click event fire but label value is not change. if i put the label too in the update panel then label value change at the time of button click. i do not understand why label value is not getting updated. suppose if i want that label should stay out of update panel and label value should change at the time of partial postback then how to write the code. i dont want put the label in any update panel.

I am using an update panel in my ASP.NET code. My problem is very simple and straight forward.
There is button which send some group SMSs to different users.
I used update panel to show UpdateProgress on my page.
On click of the button I wish to hide the button and some other labels on the page.
The problem is that after clicking the button everything else works find but these control's state does not change.
Funny thing is when i click the button, it does some checks and update a label text with error resultant values, if error is there. It works fine.
But after removing the error, I click the button once again to do the processing. Then everything on code works fine, but the label which was showing doesnot hide.
I was working on this last week and took a break from it to 'regroup' and start over. Here is what I'm trying to accomplish.
1. have a web form with dropdowns to allow the user to select font sizes, colors, background image, etc. 2. I want to the form to be updated with the new styles in an update panel. 3. Once the user clicks the apply button, I want the updatepanel to refresh with the new styles.
I tried this by creating an css on the fly, but the updatepanel wasn't picking up the new css without doing a full page refresh, (which we don't want to do). I only want the updatepanel refresh and either use inline styles, a <style> on the web form etc,
I want to know how to use auto refresh continuously in ajax update panel..What I want is,I've more than 6 update panels on my page and I want to all the panel to refresh toghether,continuously till I close the page.
This is updatepanel code. as shown in the code, i am referring to ddlClass in triggers which already calls a javascript function loadAllDefaults();
The problem is, since ddlClass is calling javascript function 'onchange' property, i cannot call any other function of backend code and I want to refresh the updatepanel on the basis of selected value of dropdownlist.
How can i do this? I have created a function in c# code in backend but I am not able to call both functions together!
after filling all criteria when i press search button the result arrives in gridview nw when searchbutton pressed after that every 20seconds i want 2 update gridview data which is in update panel
I have found an odd bug in my application. I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.Now the strange behaviour in firefox and not IE:If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.
I used timer to refresh page every 5 second.. but due to timer my multiline textbox doesn't scroll down bottom even though i used javascript to scroll to bottom..
I have a control on a page. In the control's pre-render event I'm executing some code that's taking about a minute to execute. This means the whole page is unresponsive until the control's pre-render event is finished executing.I tried putting the control inside an update panel, but it doesn't matter the rest of the page still won't render until the pre-render event of the control is finished executing. I've attached a very simple example of my code (The event that's slowing up the control's pre-render event is not Thread.Sleep(1000):
I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)
