C# - Javascript Function's Has Accessbility In An User Control From Other User Control?
Jul 13, 2010
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 defined a JavaScript function inside a user control.If I have multiple instances of the user control on my .aspx page, how do I prevent multiple function definitions in the resulting HTML code?
I have designed one user control, and used on my aspx pages whereever needed. My user control does not have tag. Now I want to call some javascript function onload of this user control. How to achieve?
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript"> </script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
I have two user controls I have some functions written on those two controls. Is it possible to invoke a function written on one user control from another user control.
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 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've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
I am trying to assign user control from another user control ..first time its binding control successfully but when we refresh the data its giving error
saying "Object reference is not set an instance".
how to refresh data from another user control ...
My senerio below :
1 Aspx page
2. User control
calling usercontrol databinding method from aspx page but once it get refreshed ,not allowed to bind it again..
I have an GridView and in GridView template field i used a user control.in the user control their is data list.in my parent page their is BindGrid function. i want to call BindGrid function of page inside Datalist RowCommand event.
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 want to convert windows user control into web user control..I have the usrDataView.cs..I need to convert this file into usrdataview.ascx.can anyonr help me?...how I can convert the file...Is any method is available..
have two user controls on one aspx page. UC1 has a grid which contains a link button column which user clicks. Based on the value of clicked cell, I need to show some data into UC2.How do I pass data from UC1 to UC2? How do I invoke a function of UC2 from UC1?
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.

how to call a function of user control from the parent page?
I have a user control inside of default.aspx page, And I have a function in the code behind of user control. I need to call that function from a code behind of default.aspx
I'm working on an ASP.net application.I had a problem with a user control I'd designed called LocationSelector. It worked great, but I couldn't use it within an ASP:UpdatePanel. I learned, by browsing SO, that I needed to put my in-line javascript in an external file and register it with ScriptManager so that there are no Response.Write calls in the Javascript.Next, I discovered that the control worked at first, but when I enclosed it within the ASP:UpdatePanel, it would stop functioning after the first AJAX postback. I read that to fix that, I needed to replace my $(document).ready call with function pageLoad() which is automatically executed with each ASP.net page load.
Several of my pages in my ASP.net application work fine (and I was really impressed with how well the framework seemed to drive the application). However, to my dismay, I discovered that my LocationSelector control no longer works at all on three of my pages. The HTML renders, but the pageLoad (which uses jQuery to bind events on control elements) does not fire.I verified this but putting alert('pageLoad'); as the first line of my pageLoad function. On the pages that work, I see the alert. On the pages that don't work, I never see the alert, even on the initial page load.What kind of problem could be causing the pageLoad function on my user control LocationSelector to execute on some pages, but not others?
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 have a user control which contains two text fields each assigned with requiredfield validators this control contains another user control contains say a button .On click of this button i need to validate the fields from the parent control text fields.I try the Page.Validate("ValidationGroup") with Page.IsValid it validates but the error message is not shown .Error message is shown only if i try to validate it from the contains which contains the required field validators ?
