View 2 RepliesI am checking to see on the form if they answer No to question one then go to comments. On the client side I added autopostback="true". So when the page reloads the random number in the label is updating to a new number. How can I avoid the random number not to be updated when the page post pack to itself?
Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load

F()

' Can return 0, 1, 2, 3, or 4
Label2.Text = n.ToString

When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads
MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
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 ?

working on .net framework 3.5 with vb
I have displayed 50% of text on label control..then i have given a dynamic link to Read More.
when i clicks on Read More it passes query string of id of that content to same page which shows full content.
Now, what I want is when I clicks on Read More link the page postback then loads the full content. So, is there any way to avoid postback using update Panel for any links generated dynamically on Label control.....?

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.
How can i scroll the page to the label control, so it is visible for Message?
I tried below code but it is not working with Label Control .
ScriptManager scriptManager =
ScriptManager.GetCurrent(this.Page);
scriptManager.SetFocus(lblMessage);
and i also Tried the below but no luck
ScriptManager scriptManager =
ScriptManager.GetCurrent(this.Page);
scriptManager.SetFocus(TxtMessage.ClientID);
Related to my previous question which is answered. The deal is, there is an update panel for modalpopup extender that is triggered by a button. The problem is when the form is submitted by a button, this modal popup is seen on the page! I do NOT want this modal popup extender to be seen when the form is submitted.

Is there a way where I could update a label control while still doing a postback method?
For example:
while (reading each row of data table) update front-end label text to show errors found in file
I have a page on which there is a textbox that is in update panel and has text changed event and autopostback=true. On the same page there is a 'Retrieve' button(inside repeater control) outside the updatepanel. Now what is happening is if user inputs data in the textbox and clicks retreive button page_load event is firing twice which is not what should be happening, one time its the partial postback due to the text changed event and second time is the page post back. I would like to restrict the second postback.
View 1 Repliesi 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.
View 5 Repliesi am using the update panel in my application in that i had added 3 dropdownlists,all of them are having the selectedIndexchange event so, once you select any item in the dropdown list i had to some operation, but the problem is that if i change the any dropdownlist in the update panel all the dropdownlists selected index methods are getting called, but what i was expecting is that when i select any item in first dropdonwlist that corresponding selectindex has to be executed not the other ones, so anybody had experienced this kind of problem let me know?
View 3 RepliesI have a number of cascading dropdownlist controls on a page. The results in dropdownlist2 are dependent on the results in dropdownlist1, pretty basic stuff.
I now would like to eliminate the terrible postback or refresh of the page that occurs after the SelectedIndexChanged event fires on dropdownlist1, is it possible to do that in Ajax?
What I want the results in dropdownlist2 to populate without the obvious refresh of the page.
I have been struggled for a day without success. Also I am not sure is this possible, since I am not too familiar with Javascript. let me know is there a way to fix my problem. Here is my problem:
What I have is a datalist and at each row it contain an UpdatePanel and inside the UpdatePanel there are a button, a slideShowExtender with related controls and a hiddenField. The hiddenField stored a second contextKey value. At page load time the default contextkey already assigned to the slideShowExtender. What I want to achieve is when user clicked the button the slideShowExtender will switch the Contextkey with the hiddenField value so that the SlideShowExtender will display a new set of images.
So far I can make everything work as I want with server side function, which executed when the button onclick. However this will generate a whole page post back, which I want to avoid. So I was thinking of using client side Javascript to do the contextkey assign and then update the updatePanel, but I am not too familiar with Javascript so I can't get it working :(

I am having an issue with an update panel, which is still causing the entire page to postback.
I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.
I am using a master page, but the update panel only appears in the content page, within the content tags.

want to do a page refresh when a button inside an update panel is clicked. Is it possible and how?
View 7 RepliesI have Requirement to update the label text as we are processing the code (Long running).
Example:
I have Label and button on aspx page.
On button Click Iam calling the AppCode which is going to do long work for me.
I want to update the label text from the appcode (which should reflect in the page then and there.)
I have tryed to pass the text value to the label but it shows the changed text only after the event for the button click is finished.
I tryed using timer but as soon as i click the button the refreshing stops.
I tryed progress template and UpdateProgress without success. (I know we can update at the start and end of proccess using this)
I dont want to use iframe (I know we can do using iframe)
In one of my webpage, I have a parent window where i have a datalist with 10 rows of images. when i click any image a pop up window(child window) opens.
The child window has a form to be filled by user. Once user fills this form, he will press the save button. Once the save button is clicked, the child window should be closed and the datalist(in the update panel) in the parent window should be refreshed.
This is how I am trying to achieve this. On click of the save button a javascript function is being called of the parent window like this: window.opener.refreshDataList();
in the refreshDataList() function I have written the following code:
{
childWindow.close();
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
This works like a charm in Internet Explorer. However in Mozilla and Chrome it doesnt work. While testing this I added an alert statement ind the refreshDataList() function like this..
{
childWindow.close();
alert("Testing");
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
Once I added the alert statement, It started working in both mozilla and chrome.
So I realize that It could be an issue related to focus. I have done window.focus()
but still its not recieving any focus and not working in Mozilla and Chrome.
add new row in gridview programmatically without postback (using update panel)?
View 7 RepliesHoping I have placed my question in the correct forum.
I am writing an application that simply updates a text box (contained in a AJAX UpdatePanel) via a thread. the eventual idea being that the textbox will be placed in the master page, and a thread will poll a table to check for status messages. 90% of the code works as it should, the only side that is not working, is physically updating the textbox. The value of the textbox is being updated, but it is not being reflected on the screen. When the text is updated in the textbox, the OnChange event is not firing (as it shouldn't), but I still need the textbox to be updated. The textbox is being updated prgramatically, and not by the user.
When the thread triggers, it just fires an event, which right now just updates the textbox with the current date time. I've tried a million and one different ways, but still no luck :( Anyone know where I am going wrong?

I've got a page that posts back constantly and if im on the inputbox thats instide the update panel i loose focus on postback
how would i get it to recognise that im on the textbox in the update panel and keep focus on it.
Below is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.
