AJAX :: UpdateMode"conditional" / Don't Want Both UpdatePanel To Get Updated At The Same Time

Jul 27, 2010

I have a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders

- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.

The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.

What is causing the partial postback not to render anything?

I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.

Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.

AJAX :: Getting Updated Value From UpdatePanel/ListView/TextBox?

Jan 8, 2011

I have a web form for payments which consists of a DropDownList (credit card, purchase order, bill me). By default, credit card is selected, and the form (a ListView within a UpdatePanel) is loaded with the user's billing address. If the user changes the payment option, the form fields change -- for example, if purchase order is selected, the billing address + credit card fields disappear and a "Purchase Order Number" textbox appears. This is done using an AsyncPostBackTrigger associated with an event in the DropDownList.My problem is that when the form is submitted, I cannot see the user-entered values within the UpdatePanel/ListView, but I can see the original values loaded in the ListView before the edits were made. For example, if purchase order is selected, I can see the billing address from the ListView, but I cannot see the newly-entered Purchase Order Number from the ListView.Here's an abbreviated version of my code. I've bolded and commented two lines where the problem appears:

AJAX :: Multiple UpdatePanel And UpdateProgress - Web UI To Be Updated With The Progress

Jan 31, 2010

I want to trigger two Async Postbacks at once using UpdatePanel's via their associated buttons such as the example at the end of [URL] When you click the first button, then immediately click the second button, the first button's message never gets updated. By clicking the second button, the first async Post back seems to be cancelled. Why does this happen?

I saw this article about only allowing one postback to occur at a time here: [URL] Is this the desired behavior for Multiple update panels? Can only one run async code at once? What's the point of it being async if you can't do multiple at once? Here's what I'm trying to do overall: I want a webpage where I click a button which causes C# code to search a certain webpage and parse it. Based on the parsed information, it should automatically start searching multiple other webpages. All the while, I want the web UI to be updated with the progress.

Button Press and the client UI says "Searching..." Then the webpage is found so I want to display "Parsing..." Then the webpage parsing is complete and multiple other websites are searched at the same so the UI will display:

Webpage 1 updating...
Webpage 2 updating...
Webpage 3 updating...

Then when the Webpage 1 -3 are done updating, they change their progress message to Complete. I just started looking into ASP a few days ago and I have two ideas how to approach this problem: zy first idea was to use UpdatePanels and UpdateProgress because they seemed easy to get in there. However, the part of updating multiple webpage status messages at once doesn't appear to be possible since I can't have two UpdatePanels updating at the same time to make changes to the client UI. The one that is started second takes over the processing and the client UI isn't refreshed until that second asynch postback is complete. Ideally, there would be a way to refresh the UpdatePanel's mid postback............

AJAX :: Fileupload In Updatepanel With Timer Doesn't Work At The Second Time

Jan 23, 2011

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.

I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.

However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

How To Identify Which Controls Are Updated In UpdatePanel

Jul 28, 2010

I have a UserControl (UC) which is in an UpdatePanel. When the UC is loaded, I run a recursive method to set tooltip for all Button, LinkButton, and DropDownList in this UC. The problem is sometimes I only update 1 control in the UC such as a DropDownList, but I have to call the recursive method on all controls of the UC. I was wondering whether there is any way to identify which controls is updated in the UpdatePanel so that I can update correctly these controls.

When Postback A Second Time Then The Page Will Be Updated With The Value I Set?

May 27, 2010

I'm using the following syntax to bind to a div element:

<div id="previewdiv"><%=Preview%></div>

Where Preview is a property on my page.The catch is that I'm creating this in Javascript on a new page in an onclick event. On the server side, I'm able to reference the new page via this property but for some reason when the page is postback the variable is getting set to the default initialized value and not to the value that I set in my page, i.e Preview = string. When I postback a second time then the page will be updated with the value I set.I could perhaps move the code to the Init but I need to get values from controls to Initialize this property.

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel

Mar 4, 2011

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.

How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

AJAX :: DOM Not Updated In IE?

Feb 15, 2010

am fairly new to AJAX, but have successfully got my page working in FF and somewhat working in Opera and Chrome.I have made a table, and populated cells of that table with an AJAX call to a sever side script.I am then using those cells in mathematical equations on the client side.In FireFox this works smoothly, In IE it fails completely. IE doesn't see that there is a value to the cell of the table, even though it displays the information in the cell after the AJAX call. Am I doing something wrong to make IE over look the fact that i have changed the DOM? or am I doing something completely impossible in IE?I need a way to let IE know that there is a value in the cell.

I have a webform that accepts a date range to generate PDF reports. I had to place a PostBackTrigger on the updatepanel and assign the button thaat generates the reports because the Response.ContentType is being set to "application/pdf".

The problem is I am updating the textbox value to the count of clients that are left out of the report generation in server side code, the count always come back as 0. I have tried multiple panels with no luck. The textbox is in the main updatepanel with the print button and that still does not work.
