I have an ASP.Net site using Forms authentication. One of the aspx pages loads a WinForms user control hosted in IE. That control must connect with a WCF service located in the same ASP.Net web site.How can I make the WCF service secure? Currently I have set the WCF service to use AspNetCompatibilityRequirements mode but the user control hosted in IE can't connect to the WCF service as it isn't logged in.

View 1 RepliesI need to know whether there will be any problem using win forms control as a custom control in my web app. Problems can be anything related to display, environment where the site is run.

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 a function that gets the position of a control.
[Code]....
All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:
function (getPosition)
{ var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>');
getPos(txtBox1);
}
I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.

I am using the below example code and have a problem where I can't pass the Request.RawUrl value into an object that extends the Control object (class Test below).When I use the line:
<Test1:Test runat="server" ID="testControl" Target="<%# Request.RawUrl %>"></Test1:Test>
I find that the Target property is never called.If I use this line instead:
<Test1:Test runat="server" ID="testControl" Target="<%# Request.RawUrl %> test"></Test1:Test>
the string value "<%# Request.RawUrl %> test" is passed to the Target property.f I use this line as explained in many posts online:
<Test1:Test runat="server" ID="testControl" Target="<%= Request.RawUrl %>"></Test1:Test>
the string value "<%= Request.RawUrl %>" is passed to the Target property.I need to get the value of Request.RawUrl passed to the Target Property of my Test control object. Does anyone have any ideas where I am going wrong?Control:
namespace Testing
{
public class Test : Control

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.
View 2 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
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 am looking for free "Open Source" controls (respectivels control libraries) for Winforms, WPF and ASP.NET with (very) liberal licences (like MIT-, Apache or BSD-Licence; not GPL or LGPL!), which can be used in commercial projects with proprietary licences.
View 2 RepliesBasically I want to call a user control from a master page. However, I need to pass an object (a List of objects to be more specific), to the user control. I'm generating the list of objects in the Page_Load of the master page. Here's the line in my master page that calls the user control.
<cu:Eventlisting1 runat="server" id="eventListing1"></cu:Eventlisting1>
This user control has a parameter called CalendarItems that accepts the list of items. However, if I try to set this inside of the Page_Load method, my control executes before the Page_Load and throws an exception saying CalendarItems is null. Is there any way around this?
EDIT: I have a drop down list on this page that determines what the list of CalendarItems is so when I populate the CalendarItems list I need to be able to read the selected value from the drop down list.
how to user control pass as parameter
View 2 RepliesIn Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists
Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note:
you do have 3 files if your making WebApplication but if your making website you only get 2 files?
UserControl.ascx
UserControl.ascx.cs
so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.
