In Visual Studio 2008 ,in my application page 'TEST.aspx' have an 'Ajax TabContainer' inside update panel , and Tab Panel "Product Group Identification" containes textboxes ,DropDownlist and button like 'Save' and 'Cancel' , on clcik of 'save' or 'cancel' buttons only dropdownList Disappears for a second and reappears this is due to Update panel.
Below you can find my sample code

Using ASP.NET 3.5 / C#. Have a page with a UpdatePanel, and a UserControl inside the UpdatePanel. When calling ScriptManager.RegisterClientScriptBlock(this, typeof(UpdatePanel), Guid.NewGuid().ToString(), script, false); the script appears to fire (have tried it with a JS alert), but the resulting script also disappears immediately afterword. I am trying to create a JS function via the script, and it is not in the Page Source after the Page is rendered. i have tried many variationsRegisterClientScriptBlock with no luck.
View 8 RepliesI've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?

View 3 RepliesI have a Page (created using master page) it has a UserControl and i want to reload the UserControl on button click (button in page outside the UserControl). I do not want to reload entire page. I want to reload just the UserControl.ASPX:

I am not sure what to do on code behind.
I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind.
[Code]....
This code gets bind using
Sys.Application.add_load(saveChanges);
I also tried the following
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.

View 1 RepliesI have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>
I think that is because the link button is rendered using a script and that script is not run after the post back.

View 2 RepliesOn my Form I have 2 gridviews namely; gvCRSearch (that displays search results) and gvCRView (that displays all the change requests raised).. Now, when the records are more than 10 in gvCRSearch it automatically creates a navigation number i.e., 1 2 3 Same thing happens to gvCRView
What is wrong is that when I click the navigation i.e., ( for example 2) on gvCRSearch
1) the gvCrSearch becomes visible = false
2) the gvCRView if it has a navigation number is moved to 2
So the effect is seen the next view (gvCRView) and the gridview (gvCRSearch becomes invisible)
the asp is as shown;
Code:
<asp:GridView ID="gvCRSearchView" runat="server" ShowHeader="True" AutoGenerateColumns="False" DataSourceID="CRSearch"
BackColor="White" BorderColor="#600000" BorderStyle="Solid" BorderWidth="2px" CellPadding="3" Font-Size="89.5%"
ForeColor="Black" GridLines="Vertical" AllowPaging="True" PageSize = "10" AllowSorting ="true" CssClass = "MainGridView">

I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

I have a dropdown on page, a place holder and a save button on my form.Now, I am creating a textbox on selectedIndexChanged event of dropdown list and adding it to placeholder. And on button click I want to access the control, but on click event, I find the textbox as null. Here is my code
protected void Dropdownlist1_SelectedIndexChanged(object sender, EventArgs e)

if (Dropdownlist1.SelectedValue != string.Empty)
And button Save click event

Yesterday (Thursday Sep 10th 2010) I was happy to have a TabContainer working fine on a simple page as im learning to use it.
On the page was:
1) Ajax Script manger.
2) 1 command button (it would make label1.text = "hello world"
3) A Ajax TabContainer with 2 tabs...
4) Label1
That was it and it was working fine in Chrom and IE Woohoo.. I go home...
This morning I load it up to keep working way and doing more with it.... Chrome is my default browser, it loads and I click tab2 then tab 1 all is well.... I click Butto1 and the hole TabContainer disapears..
After much dinging I find it still works in IE but that my Chrome has updated (on its own): (I notice only one ICON in Chrome in the uper right corner by the addres bar... Only the Wrench ICON, No more Page ICON.. So I check and sure enough Chrome did a push to V 6.0.472.55.. Anyhow thats the difference and now TabContainer goes poof/disappears when clicking a button that refeshes the page.

I have a div inside a user control that is displayed by the user after some event. I want to hide this div when user clicks anywhere elese on the page but not on the div (or not on any element that is inside the div).
If it wasn't a user control I could use body's clieck event to check the target, but because this is usercontrol that is hosted by other page I can't just "play" with it's elements. How can I achieve that without using body of the hosting page?
I would like an UpdatPanel to update it's content once a button is clicked - this button is contained within a UserControl placed on the webpage.However, I cannot just simply reference it using the AsyncPostBackTrigger's ControlID property, because the button is not situated directly on the webpage.
