VS 2005 Update Panel To Exclude Part Of Page
May 7, 2010
Got some small(Basic) doubt on update panel. Using Update Panel, Is it possible to stop updating a part of Page? The problem is, I have a very small portion of page, in which I'm updating some data using JavaScript, Which I want to retain(in ASP language Maintain State) for any post back that will occur in Page. I thought placing update panel will solve the purpose, But as per Update panel principle, It will updates only that part of page based on the Triggers conditions. I want it exactly in reverse way (It is very difficult for me to place Update panel for the entire page excluding the small part).

i 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 have to update a gridview inside an updatepanel in a button click.The thing is i'm having gridview in contentpage.I have placed scriptmanager in masterpage.when i clicked on the button to trigger the updatepanel,no update is happening in gridview.Moreover,after placing updatepanel control in contentpage,i saw a redcurvedline (which is an error basically) below the updatepanel control's text which is showing an error as "Element 'updatepanel' is not known element.This can occur if there is a compilation error in the website" in .aspx page's source view.I have attached the screen shot here of that page here for your reference.
But it's working in ordinary web page.

Not sure how to solve this problem so thought I would ask here, as always.Scenario:I have a page where you can add a book review. But for each book, you can have multiple authors from the list available in the database.To add a new author for a book, you post to a separate action. when you do this, this page refreshes, shows all the authors you have added for this book, but loses the information in the other form fields.
If I posted the authors using Ajax, they would be added to my list, and my form controls would be fine, but then the part of the page that displays the authors currently added would not be updated to show the new author.I'm thinking maybe I can make the added authors a partial view and when I post the new author asyn I could somehow tell that part of the page to update.

I 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?

We 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'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.

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 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).

Is there a trick to using UpdatePanels with timers? I put a gridview on my page in an update panel that refreshes every 10 second like:
Code:
<asp:Timer runat="server" id="UpdateTimer" interval="10000" ontick="UpdateTimer_Tick" />
<asp:UpdatePanel ID="udpGridView" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger controlid="UpdateTimer" eventname="Tick" />
</Triggers>
<ContentTemplate>
<table width="98%">
<tr>
<td width="100%">
<asp:Label ID="Label11" runat="server" Font-Bold="True" Font-Size="Larger"
Font-Underline="True" Text="Script History"></asp:Label></td>
</tr>
<tr>
<td width="100%">
<asp:GridView ID="gvScripts" runat="server" AutoGenerateColumns="False"
Width="95%" UseAccessibleHeader="False" AllowPaging="True">
<Columns>
<asp:BoundField DataField="Vehicle" HeaderText="Vehicle" />
<asp:BoundField DataField="Receipt" HeaderText="Received" />
<asp:BoundField DataField="Status" HeaderText="Status" />
<asp:BoundField DataField="script" HeaderText="Script" />
<asp:BoundField DataField="sentTS" HeaderText="Sent" />
<asp:BoundField DataField="returnMessage" HeaderText="Return Message" />
<asp:BoundField DataField="returnTS" HeaderText="Returned" />
</Columns>
<SelectedRowStyle BackColor="#CCCCCC" />
<HeaderStyle BackColor="#000099" ForeColor="White" />
</asp:GridView>
</td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
I'm not doing anything in the tick, just letting it call the Load event for the Update Panel. Whenever the Timer ticks though, if I am typing in another area of the page I stop being able to type, and lose the cursor, and I have to click around to get it back, so it makes the page pretty unusable.

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.

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.

I've two SqlDataSources and two Repeaters, each repeater contains one hyperlink (i also tried using web server button and anchors). The hyperlinks fetch from the database some values and in the NavigationUrl property I use a string.Format method to create a parameterized url, to pass for the browser, then second repeater is populated according to the value passed in the url which is originally passed by the first repeater's hyperlink. this is my sample code : [URL]
<asp:ScriptManager id="Scrptmanagr" runat="server"></asp:ScriptManager>
<asp:UpdatePanel id="updtpanl" runat="server">

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">

SelectCommand="SELECT [alphabet_id],[arrange_by_id], [value] FROM [alphabet] WHERE ([arrange_by_id] = @arrange_by_id)">
<SelectParameters>
<asp:QueryStringParameter Name="arrange_by_id" QueryStringField="SortingType" Type="Int32" DefaultValue="1" />
</SelectParameters>
</asp:SqlDataSource>
<br /><br />
<asp:Repeater ID="Repeater2" runat="server" DataSourceID="SqlDataSource2">
<ItemTemplate>
<asp:HyperLink ID="hyper1" runat="server" NavigateUrl='<%#string.Format("{0}?SortingType={1}&SortBy={2}",Request.AppRelativeCurrentExecutionFilePath, Eval("arrange_by_id"),Eval("value"))%>'><%# Eval("value")%></asp:HyperLink>
</ItemTemplate>
<SeparatorTemplate>
|
</SeparatorTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>
Now! everytime I click any of the hyperlinks it causes a full post back and refreshes the page!

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

<div>
<asp:ScriptManager ID="sm" runat="server" />
