Web Forms :: Loading Usercontrol From The Menu Gives Javascript Errors?
Mar 14, 2011
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.
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 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.
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.
Is there any way to load [main] menu items in run-time? for instance using WebServices? My web application's main menu is so big and takes a long time to be loaded. So that, i want to load its items on demand. I want to load the sub-items of the menu item user is hovering.
I was wondering if there's a way in Umbraco to log errors that we get when it fails to load xslt or user-controls. Generally it shows a red box saying it couldn't load the control and stuff. Is there a way to properly log this?
I have used the following controls in my web page.
1.Menu 2.Multi view 3.view 4.Gridview
But my problem is...whenever i clicks on the menu item it loads particular content individually. I mean if i click on menuitem1 it takes some time to load Gridview1 , after if when i click on menuitem2 again it takes some time to load Gridview2. Is there is any way to load all the menu items content during first time of page load. So that we can avoid loading time while switching over from one menu item(tab) to another.I have used the following code
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!
I recently upgraded from VWD 2008 Express to VWD 2010 Express. A problem has developed in that the website's graphics no longer appear in Design mode, there are "Error Creating Control" error messages that did not exist before, and also debugging errors that did not exist before. (Note: these problems did not exist when I first used VWD 2010; they may have originated with recent automatic Windows updates (I use Vista Home Premium SP2 with IIS 7)). The problem exists if I open the website either as a project file or as a website directory.
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.
After it is done, I can't click on my calendar control. I was hoping to add somethign that would force a refresh in the script, but nothing I do works.
i designed an user control within that one html textbox input control is there. now i want to drag and drop this usercontrol into an aspx page, my doubts is how can i validate that user cotrol html input control has data or not using javascript? then im want to read that data from aspx code behind, how to do this?
i m using master and content page and i have created Usercontrol for Left menu of jquery but my menu working fine in html markup but not in content page
jsText is nothing but Name and Value pair strings. Example : "KEY1:txtName, KEY2:txtDOB" In UserControl, I am calling the above Class method to pass all the textboxes and calling the JS file to validate the registered controls. Then, I am calling that Usercontrol in ASPX page. Here I am unable to validate the controls as it is saying "KEY is undefined".
I have a javascript embedded in my extended gridview control that reference the grid control. Example:
[Code]....
HTML code:
[Code]....
way to determine the gridview object in javascript. I want to make it generic so that if I use this gridview in any other control it should work instead of hardcoding the name.
I have a website that uses a master page that contains the navigation for the site.The navigation buttons are images.Some of the navigation button images have hover menus tied to them.Those hover menus contain several image buttons, so as to create a drop down menu affect.The problem I have is when any of the pages are loading all of my hover menu image buttons flash on the left side of the screen for a second or less as the page is being rendered.Can this be stopped?
I need to access controls of aspx page and usercontrol page through the external .js file. I created a global varaible in the aspx page
<script language="javascript" type="text/javascript"> var loadPanelID = "<%=ajaxLoadingPanel.ClientID%>"; </script>
Now I pass this value in the onclick event of button click (Let the funtion name be Fun(loadPanelID) ) . The controls is recognised in the .js file. Everything is fine till now. Now i need to call the same javascript method Fun() from the button click of usercontrol.
<script language="javascript" type="text/javascript"> var loadPanelID = "<%=ajaxLoadingPanel1.ClientID%>"; </script>
I have ajaxLoadingPanel1 in the usercontrol and I have defined global variable as in the first one in ascx and passed that value to Fun() method. But this time it gives error called "loadpanelID" is undefined.
I am trying to prevent VS from breaking on JS errors.
I have the following settings:
In IE, under Tools->Internet Settings->Advanced (tab)->Browsing Disable script debugging (Internet Explorer) is checked. Disable script debugging (Other) is checked.
In VS, under Debug->Exceptions->Common Language Runtime Exceptions JScript Exceptions (thrown and user-unhandled) are unchecked.
In VS, under Tools->Options->Debugging->Just-In-Time Script is unchecked.
There are some JavaScript errors that I just don't care about and it is driving me insane having to deal with them.
I started to use the MultiSliderExtender and wanted to create a WebUserControl with it But every time I add more then one slider I'm getting Javavascript erros
Heres the Code of ASP page:
[Code]....
Heres the Code of the WebUserControl:
[Code]....
When the page Opens a JS Error occours in some ASP generated JS Code
[Code]....
d contains the ID TextBox2 but somehow the TextBox2 object doesent exists on executing this line resulting in null referenc error. If i put All the Code of my WebUserControl into the ASP Page it works fine
If i remove <MultiHandleSliderTargets> ... </MultiHandleSliderTargets> from the Control no error occours. But i need two Sliders
Adding sliders in Page_Load ended with other Execpetions (AjaxControlToolkit.MultiHandleSliderTarget is not serializable).
So my question is: How to make a this WebUserControl working.
I'm using VS Web Dev Express 08, .Net 3.5, ASP Ajax Kit ver 3.0.30930.0 all on Windows 7
