I have a script manager and 3 update panels on my page. I am not very familiar with AJAX but I would think anything in the contentTemplate would not cause a postback and page reload, but they all do, here is the outline of the SM and UpPanels
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="sm" runat="server" />

View 1 Repliesi have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.
I am trying to wrap my head around update tabels, the thing thats boring me is if i should use one or multiple panels. When i load a control into my update panel should that control have it's own update panel? Or will it use the updatepanel it's loaded into? Is it even possible to dynamicly load a control into an updatepanel and do async post backs from there? Let me paint you a picture:

I am hoping someone can help me out. I have a web application that contains a usercontrol think "employment details" a user can enter a previous employment detail.
I have created a page that contains an update panel a placeholder and a button. The button I want to use to load a new copy of the same usercontrol. Can anyone point me in the right redirect?
I have a update panel on the ASPX page,When thepage loads the content in the update panel shouldnot load ( Update panel should show the Updatepanel progress control) but after page load update panel contents should load . How do i get this efect.
View 3 RepliesI have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

Now i was trying to use an UPDATE PANEL, in order to when i click button Save, only the DIV updates. Because the whole DIV is closing when i click on SAVE, even if i put a div in an update panel.
is there any other way by which we can update a section in page except Update Panel?
View 1 RepliesWe have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?
I have a page showing the number of hits(or views) of any selected item. The hit counter procedure that is called at every page load i.e
if (Request.QueryString.HasKeys())

// get item id from icoming url e.g details.aspx?itemid=26
string itemid = Request.Params["itemid"];

In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
My coding is as follows:
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (Session["sesUserName"] == null)
{
Response.Redirect("sessionExpr.aspx", false);
}
else
{
lblStatus.Visible = false;
pnlEvaluate.Visible = false;
if (!IsPostBack)
{
fnLoadDropDown1();
fnLoadDropdown2();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
public void fnLoadDropDown1()
{
dsLoadDD1 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD1.Tables[0].Rows.Count > 0)
{
ddTestTitle.DataTextField = "vchTestTitle";
ddTestTitle.DataValueField = "intTestID";
ddTestTitle.DataSource = dsLoadDD1.Tables[0];
ddTestTitle.DataBind();
}
}
public void fnLoadDropDown2()
{
dsLoadDD2 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD2.Tables[0].Rows.Count > 0)
{
ddUser.DataTextField = "vchUser";
ddUser.DataValueField = "intUserID";
ddUser.DataSource = dsLoadDD2.Tables[0];
ddUser.DataBind();
}

I am using VS 2010 with .Net 4.0. I am using a HoverMenuExtender to display a text but just after the page is loaded, the popup panel is already displayed.
View 5 RepliesI have an update panel in a user control and I am adding multiple instances of it for example 5.
When that update panel refreshes the page load occurs 5 times.
How can I prevent it only for once?
I can't figure out why, but before my form is even displayed, the CheckChanged event fires. I don't even have a chance to check anything. Has anyone seen anything like this?
View 3 RepliesI have a form, with an update panel and the EnablePartialRendering set to true on the page. Here's my problem, the page size with every AsyncPostBack gets larger, even if my code makes no changes to the markup. It also, never stops... it just keeps growing about 3-4K with every AsyncPostBack. If EnablePartialRendering is set to false, full postbacks do not cause the page size to grow like that. It's like it's sending resources and then never getting rid of them out of the page even though they're not being used because an updated copy has come down.
1.) Is it supposed to work like that?
2.) If it's not, what can I do to not have 4K added to the page size everytime an AsyncPostBack occurs (not again, full PostBacks do not have that same behavior).
3.) This behavior happens whether I compress the ViewState or not (I am using ViewState compression). However, the ViewState size is NOT growing... it's the size of the content in the page that is (I'm monitoring the ViewState size/the Page Size closely).
I have a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..
I have an UpdateprogressControl on my page and an Update panel. The UpdateProgress is not associated with the UpdatePanel as I want the update progress to show when the user clicks on any control in or outside the Updatepanel content. However the update progress only shows when a control is fired from within the update panel and not on any control outside the update panel.

I have used the update panel for avoiding reload page.but because of update pane radiobutton event not fired properly. I want to show Popup widow on link click.This popup contain the gridview.When I choose radiobutton which belogs to that gridview popup will be closed and as per grid row selection data will be display in text box which are belogs to form rather then
popup.Now because of update panel I can avoid reloading page but above functionality doesnot work.
in one table
<asp:UpdatePanel ID="Operations" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="txtOperations" runat="server" Font-Names="Code128bWin" OnTextChanged="OperationEventHandler" AutoPostBack="true"></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID = "txtOperations" EventName="TextChanged" />
</Triggers>
</asp:UpdatePanel>
and a label in other table
<asp:Label ID="lblOperation" Text="OperationID not Valid" runat="></asp:Label>
and the code behind page is
protected void OperationEventHandler(object sender, EventArgs e)
{
GridView GridViewValidOps = new GridView();
GridViewValidOps.DataSource = TB.ValidateOperations(txtOperations.Text);
GridViewValidOps.DataBind();
if (GridViewValidOps.Rows.Count <= 0)
{
lblOperation.Text = "OperationID Not Valid";
}
}
Is there a way to use the same update panel for the label , because i want the value of the label to be updated if the user enters wrong value.
