User Controls :: JavaScript Not Working Inside Web User Control
Apr 16, 2012
I hava a page default.aspx having master page abc.aspx and web user control login.ascx i want to call perform simple alert function on login button but not on client click event. For e.g
Protected Sub BtnMyIpLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnMyIpLig.Click
'Some Validation part here for user login
'then my if condition like
If flag_alert = 0 Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "btnflag", "alert('Your Download / View Limit Exceed More Than 90%');", True) End If
I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
I have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.
Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.
The code behind for the user control executes as expected, but any reference to child controls are null.
It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.
Autocompleteextender not working inside an user control tried all ways. i have a custom function.. inside the cs file itself like the following :-
[Code]....
I did something like this and it worked properly when it was in aspx but when i changed all this to ascx and when i added the user control in aspx the autocomplete is not working. say enablecontext = false; i have even tried that.. its not even reaching till that function. moreover i need contextkey to validate different autocomplete controls inside my page.
I've set up a CustomValidator with a ClientValidationFunction as:
<asp:CustomValidator ID="CustomValidator1" runat="server" Display="Dynamic" EnableClientScript="true" ClientValidationFunction="checkClients" ErrorMessage="You must select at least one client or staff" SetFocusOnError="true"></asp:CustomValidator> <script type="text/javascript"> function checkClients(sender, args) { [code]...
All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like: <!--#include file="EditProject.ascx"-->
I tried this but no luck!
Parser Error Message:
There can be only one 'control' directive.
Source Error:

I have created a real simple templated UserControl and
I can now add this control to my Asp.net WebApplication using:
[code]...
i can embed this in a page (aspx) but i is not working in usercontrol (ascx). when i use this inside usercontrol, the designer file (.ascx.designer.cs) itself not getting generated.
getting the following error:
Element 'Box' is not a known element. This can occur if there is an error in the webpage, or the web.config file is missing.
Update: sometimes it works! i created couple of controls. it works in some place and it doesnot works in someother place.
I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see: http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I am using a usercontrol which has two textboxes named txtUserName,txtPassword and a button named btnSubmit.I am using this usercontrol in my webpage.I want to show alert message in the webpage if the user didnot enter the username or password .
Now the weird thing is I have a user control UserControl1 in which I put some JavaScrdipt logic there, and I have another user control UserControl2 and I registered both in the page called Page1.aspx.I would like to call the JavaScript function resided in UserControl1 from UserControl2, however, I got an error saying the function is not defined. I think both user controls are loaded before I use them then I think the JavaScript function can been seen anyway in that page.
I have created a user control. Usercontrol contain a image. Attached a click event on image jusing javascript function.
image.onclick = function (e) { //some code };
Now this user control is added on aspx page. Thsi is working file first time. however when the page is getting postback this event is not working.UserControl EnableViewstate is true.What should be done?
I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
I'm working on a user control that renders couple nested divs (a rounded corner box to be frank). This is a templated user control, which means that user can put any control he wants into the header, body or footer of this box. Everything is working fine, except the fact that server-side controls can't be retrived from my box. Take a look at this code:
[Code]....
Now codebehind of that control:
[Code]....
I have cut out all the unimportant stuff.Now when I use this control:
[Code]....
I want to access controls in page codebehind file (on Page Load): LiteralNewses.Text=""; but compiler returns an error that LiteralNewses doesn't exist. Also FindControl method can't find this literal.Any tips on what's wrong with this code? According to MSDN, setting TemplateInstance to Single ensures that controls from template will be accessible but not in my case...
I've created a multiple uploadfile user control - upload_multiple_files.ascx:
[Code]....
which has an update panel ID = up_upload_multiple_files this user control will be placed inside a modalpopupextender. My question is when I click in any button AddFile, RemvFile, Upload there's a postback so the page is reloaded and the modalpopupextender disapears Is there a way to to troubleshoot this?
I have create one user control of personal details, and write the geting data from database method and Load the entities in respective field,then how to bind user control in gridview and how to accecc Id of user control in aspx page.
I have a user control with a textbox. I am loading it at runtime on parent page with code behind.After click of button on a parent page i need the text of that usercontrol's textbox.
I tried with following code but it does not work for me
myusercontrol us = new myusercontrol(); TextBox textbox = (TextBox)us.FindControl("txtusercontrol"); string str = textbox.Text.ToString();
I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.
