How to determine if a user control is contained by the update panel that triggered async postback

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?At the moment, the only pseudo logic for this I can think of is?'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)'Try to find the user control as a child of the update panel

page inside update panel doesn't refresh the session object after postback of any control



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)

Any help is greatly appreciated.

Thanks in advance

What is difference in Page Life cycle in general postback and postback due to child control of updat



Since both general postback and postback due  to child control of update panel causes a postback and all events of page are loaded then what is the actual difference between  general postback and postback due to child controls of update panel.

Also, it is said that childern of update panel do a partial postback .Then how it is a partial postback ?? I am seeing that whole page life cycle is  happening even in partial postback ?

Can anyone explain this ?

The article ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript was added by Aamir Hasan on Thursday, August 19, 2010.

Dynamically load user control without postback


Hi all,

I need urgent help. (c#coding)

In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.

While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.

Is there any way to load controls without postback? I Really need help as soon as possible.

Here is my code:

protected void Page_Init(object sender, EventArgs e)
        if (Session["control"] != null)
            string c = Session["control"].ToString();
            if (c == "1")
                iuc = (IlkogretimUC)LoadControl("~/Controls/Ilkogretim.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "2")
                luc = (LiseUC)LoadControl("~/Controls/LiseUC.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "3")
                youc = (YuksekokulUC)LoadControl("~/Controls/Yuksekokul.ascx");

Knowing the event occured in user control in current page

Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

Change part of a page without full postback


I have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript, but I don't know how and would appreciate some help. Thanks!

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

Control Values When Returning to Page


Why do controls value not persist when returning to a page (e.g. via browser back button)?  If I set control values without utilizing a post back the controls will maintain their last value when I return to the page.  If I set a control value and then call a post back, the control value is reset to the default value when returning.

I have many pages with a gridview, and a textbox which is used to filter the gridview contents.  I set the filter textbox, filter the gridview (postback), go to another page, and when I return to the gridview page (via back button), my filter textbox is reset empty, and the gridview is the original (unfiltered) data.

What concept am I missing here?

Thanks in advance...
