I ma trying to load a usercontrol into a table. My usercontrol contains some literal controls.
I can't set the text of these literal controls to anythign, as in my code-behind of my control, whenever I try to access my controls, they come back as null.
My user control code:
[code]....
I would like to load UserControl dynamically from DLL in the bin directory.
The dll contains several usercontrols which dynamically create webcontrols within them.
I do not have Virtual Path of the UserControls to use in LoadControl(String virtualpath) and LoadControl(Type, object[]) does not work(why the heck is it there in the first place anyways).
provide me some sample code which takes either the path of dll or assembly name "ServerControls" to load usercontrol "UserControl1" dynamically into placeholder "PlaceHolder1"
I have an asp.net page that has menu which loads user control dynamically when the menu item is clicked.Now in the user control i have some buttons calling javascript on clientClick.When i click this button,it throws javascript error
Microsoft JScript runtime error: '(function name)' is undefined
Here is the code snippet:
function CheckUpload() {
var flag = validatePage();
var Checktext = $("#HyperLinkUploadFile").val();
if (Checktext != '' && flag)
flag = true;
return flag;
}
<asp:LinkButton ID="btnNotifyOA" runat="server" Text="Recommend Award and Notify OA & AO"
ValidationGroup="Notify" OnClick="btnNotifyOA_Click" OnClientClick="return CheckUpload();" />
The above linkbutton and javascript is inside a usercontrol.
In the process of migrating an old VS2003 web app to VS2008, I'm running into this issue and haven't been able to find a resolution. Sample code: "Default.aspx" has a PlaceHolder(ToolHeader). In the Page_Load(), we dynamically load a user control passing in the virtual path to a helper method [public Control ParseUserControl(string virtualPath)]. This reads the content from the physical path, returns
a Control from ParseControl() method. I immediately get the following error when I open the default.aspx page in browser.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load type 'DynamicUC.UcControl'.
Source Error:
Line 1: <%@ Control AutoEventWireup="true" CodeBehind="UcControl.ascx.cs" Inherits="DynamicUC.UcControl" %>
Can't figure out why it can't load the type. Namespaces are looking right. I try removing the Inherits="DynamicUC.UcControl" attribute from the "ucControl.ascx", it loads the page fine. Also, this control is a simple one and has no code behind. There are others with actual code behind. They won't work if I remove the Inherits attribute.

if I have a data grid on my web page along many other controls, and that datagrid is fetching some data while the page loading.
The page won't load until data grid finish fetching .

but filename is empty and when i put the flvControl.fileName = config.applicationURL & "/video/" & video.folder & "/" & video.videoFile
before flvControl = CType(LoadControl("media/flv.ascx"), mysite.flv) i get object reference error

i am using Master Pages for my site(VS-2005). A page in my site gives user information about a city which he has selected from a drop down list. I want that when a user selects a city's name from a drop down list control, then a particular HTML file of that city should get loaded into that page. The ASP.NET page should remain same but only loaded file should change. If a user has chosen London then the HTML file of London should be loaded, if the selection is Paris then XML file of Paris should be loaded in the same Page. How can I do that ?
View 5 RepliesI have added usercontrols to aspx webpage. But usercontrols page_load event is firing twice every time. tell me how to resolve this issue.
View 3 RepliesSo I'm trying to dynamically load a usercontrol into a placeholder in another usercontrol inside a updatepanel.
basically I've got this markup:
<asp:UpdatePanel ID="upPopup" runat="server">
<ContentTemplate>
<UC:Popup runat="server" ID="UC_Popup" />
</ContentTemplate>
</asp:UpdatePanel>
And then this markup inside that usercontrol (Popup):
<div id="modal">
<asp:PlaceHolder ID="phPopupPlaceholder" runat="server"></asp:PlaceHolder>
<asp:Label ID="lblModal" runat="server"></asp:Label>
</div>
In the codebehind of the popup usercontrol I have:
public void Show(UserControl control) {
this.phPopupPlaceholder.Controls.Add(control);
this.lblModal.Text = "Loaded";
}
And I call this show method elsewhere with:
Popup.show(new MyUserControl());
Nothing loads into the placeholder though.
But in the show method I can load regular server-controls fine like this:
this.phPopupPlaceholder.Controls.Add(new Label(){ Text = "Label!" });
Can anyone explain to me why regular controls are loaded fine, but my usercontrol isn't loaded?
I have to load the values to parent page from the popup page. The popup page will be in another website(saparate server).
I used opener.document.getElementById('parentcontrolID'), this is working fine if i run in the local(i created saparate virutual directory for popup page website in my local machine) system the values are loaded properly. but Once i move to the different servers it's not working. getting this javascript error message "Object doesn't support this method or property" in the popup page bottom left corner.
What will be the problem.
Whether we can load the value to parent page from popup page even both are in saparate server?
On my page I have a placeholder where I load a usercontrol when I select an item in dropdownlist.
protected void ddlLoadCtr_SelectedIndexChanged(object sender, EventArgs e)
{
Control userControl = LoadControl("../AleSettings1.ascx");
plchldSettingsControl.Controls.Add(userControl);
}
If I press F5 (IE) after user control was rendered, I get IE's warning window that IE needs to resend the information....
How can I prevent it and why does it happen?
UPDATE:Maybe there is another approach? I want to load specific control (with it's markup) when user selects it from the dropdownlist.
if a postback is made the control shouldn't disappear(only if another control was selected from the dropdownlist) Everything is inside update panel!
Is there a way of stopping the main page waiting for a usercontrol to load before it can finish loading?
I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.
Yesterday i asked from u 'Adding-WebUserControl-to-the-page-or-panel-by-client-side-code'.
from scratch it do'snt work properly. but today I downlowded again. its work rightly.
but it just show one control on it (just show lblMessage).
How Can i shows any number of controls on the WebUserControl. ex: button, picture, ...?
I have a web page that has lots of different parts to it (i.e many data grids). The page takes quite a while to load up because it is running all the stored procedures to populate each grid so the user is left waiting for the whole page to load.
I would like to improve this by loading the page a section at a time so that to the user is not left waiting for the whole page to load up before anythin can be viewed.
What is the best way to tackle this problem. Do i need to use threading or would i being going down the wrong path looking into that.
if Panel have any aspnet control,panel not popups.otherwise working.whats wrong here ? is it impossible ?

I want to display a web page on the click of a button in another asp.net web page. how to do it using AJAX
View 1 RepliesA portion of my site requires data from a web service, with takes 7-8 seconds. How can I load the rest of the website, show a Updateprogress for the data which comes from the service, than show the data once obtained trough a updatepannel. Some working project would be great.I need the server to retun the page before the data from service is obtained, and add that data later using ajax
View 1 RepliesI 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.

Table 1:

Table 2:

So Table 1 shows up (just the header row, before the table body is populated), but Table 2 doesn't, even though I can see the markup in the source code. Strangely enough, if I remove the class from Table 2, it shows up (but I still can't get any of my JavaScript events to fire on it).
Here is the CSS class ("data_table"):
