View 1 Replies 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?

I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :

The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?

I have a webform which has an updatepanel with a combobox, add button, delete button and a table. The functiion of the two buttons is to add or delete table rows. However, the table is getting cleared everytime the combobox item is selected. Is there anotherway of retaining the table contents?The code for the updatepanel is:
<asp:UpdatePanel ID="UpdatePanelTreatment" runat="server" UpdateMode="Conditional">
<triggers>
<asp:PostbackTrigger ControlID="cboTreatment" />
asp:PostbackTrigger ControlID="btnAdd" />
I have an Usercontrol which has a update panel that being postback by a timer, and it is nested in a parent page which has its own update panel. Every time that the update panel in UserControl cause a postback to server my main page's scrollbar being reset to top or buttom of the page. I enabled viewstate of parent page but nothing, and when enable parent page's MaintainScrollPOsitionOnPOstback it cause a problem for Usercontrol updatepanel postback !
View 2 RepliesI'm reading about the UpdatePanel and how it interacts with controls inside & outside of it.
My understanding is that the usual ASP.Net pipeline takes place when posting from within an UpdatePanel-- Page load etc all fire off as normal-- except when the prerendering stage is reached. In that case the ScriptManager does a final check and only renders those controls within the UpdatePanel and skips the rest. That's my understanding at least.
Sounds good, but for argument's sake let's say I have a TextBox located outside an UpdatePanel. If a postback occurs from within that panel, the TextBox's properties can still be set in the page load method, but those changes will not take effect. (normally; it is possible to postback the entire page from an UpdatePanel)
Is that correct? What happens to that TextBox's ViewState in this instance? Is it updated based on what happened to it in the page load method or is that modification tossed out because it wasn't in the UpdatePanel?
i am using an updatepanel and loading diffrent user controls(.'ascx') in to it by the server side.
in every user control i have diffrent controls, max 4 controls in one user control.
no matter what control i am using when ever i cause an event from any control on the user control
the page postback twice and the item/option/text ichoose or checked or wrote in the control disappers, and the control
that caused the event returns the his original position like no change was made to it.
does anybody have any ideas or have a suggestion what causes thes double postback.
I have a simple form containing a gridview that displays some records. Everything works fine but I was hoping to wrap the grid view inside an updatepanle to prevent a full postback (flickering) when paging.
It doesn't seem to matter what I try, paging always causes a full postback which causes the page to flicker. What am I doing wrong?
Here's my markup:

And here's my aspx code:
[Code]....
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>
I have problem to show method value on asp:Panel.
This is my *.aspx code :
[Code]....
Code Behind :
[Code]....
In this case, I can't show value myMethod at code behind to aspx file where this method is called.
If I use postBackTrigger in upControl updatePanel then the method(myMehod) will show on upShow updatePanel. But the updateProgress doesn't work.
i have dropdown put into a asp.net panel:
ddl.AutoPostBack = True
pnlFilters.Controls.Add(ddl)
if dropdown list item is two words then eg:john smtih, then it must go to url after post back as john-smith. how to do this.
I have a series of div's inside an update panel, these divs have a margin-bottom defined in css. In IE8, when I do a async postback these margins are all removed. All the other styles are fine. If I turn on compatibility mode this does not happen. In Google Chrome the margins are maintained correctly after the async postbacks.
View 1 RepliesWe have a fairly complex content management system where we start with a blank page with just an updatepanel, then in the init function add all the controls, this all works fine.The problem I'm having is that when the loginform control logs in, we get data back from the server that looks like:
|#||4|64|pageRedirect||%2findex.aspx%3feventid%3d1079%26AspxAutoDetectCookieSupport%3d1|1|#||4|15647|updatePanel|ctl00_ContentPlaceHolder1_contentup|

i got a strange problem. my project was ok before implimenting ajax. i have just implimented ajax in one page only with Tabcontainer and updatepanels only nothing else. almost all controls are devided into different Tabs with respective update panels.
mostly it is working ok. but the problem is :
1. in some controls i am not able to write anything even the control is "Enabled=True" and focus is on the same control after partial postback.
2. and as soon as i press Tab control goes to Address bar.
3. some time tab key is also not working.
here some code :
[Code]....
Here the Logic :
as soon as i type inception date; expirydate is automatically calculated and focus should come to sumassured. after this it should allowed to enter sumassured amount, which is not allowing to write.
As soon as i change tab and come back to original tab then i can write values normaly.
I have a quite strange situation where I have the following code:
[Code]....
This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):
[Code]....
When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.
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 have an gridview inside of a multiview inside of an updatepanel. I create all this dynamically with code (AutoGenerateSelectButton=true).If the SelectedIndexChanged event is fired, there is a full postback. How can I avoid this?
