    [CLOSED] Calling UserControl Methods from parent form

    I will try to explain this without an example (which is on a standalone network).

    I have a form that that loads two user controls. These user controls each have a number of fields on them. For testing purposes I have added a "Fillout Defaults" button on the main form that fills in all of the fields so I can routinely perform testing. When I press the button on the it calls a direct event. How can I call to the user controls to each fillout their default values.

    ...
   <ext:UserControlLoader runat="server" ID="uclGeneral Path="~/CRTS/urGeneralControl.ascx" />
   <ext:UserControlLoader runat="server" ID="uclApproval Path="~/CRTS/urApprovalControl.ascx" />
...
   <ext:Button runat="server" Text="Fillout Defaults" Icon="PencilAdd">
      <DirectEvents>
         <click onEvent="FilloutDefaults" />
      </DirectEvents>
   </ext:Button>

    Hi Chris,

    Please look at the example.

    Example Page
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void ApplyDefaults(object sender, DirectEventArgs e)
    {
        TestUC c = (TestUC)this.UserControlLoader1.UserControls[0];
        c.ApplyDefaults();
    }
</script>

<!DOCTYPE html>

<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>
</head>
<body>
    <ext:ResourceManager runat="server" />

    <ext:Button runat="server" Text="Apply defautls" OnDirectClick="ApplyDefaults" />

    <ext:UserControlLoader ID="UserControlLoader1" runat="server" Path="TestUC.ascx" />
</body>
</html>
    Example User Control
    <%@ Control Language="C#" ClassName="TestUC" %>

<script runat="server">
    public void ApplyDefaults()
    {
        this.Label1.Text = "Hello!";
    }
</script>

<ext:Label ID="Label1" runat="server" />

    Ok the example works, but I am having a tough time getting it to work with my user control definition.

    Example Page
    <%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

   <script runat="server">
      protected void ApplyDefaults(object sender, DirectEventArgs e)
      {
         TestUC c = (TestUC)this.UserControlLoader1.UserControls[0];
         c.ApplyDefaults();
      }
   </script>

<!DOCTYPE html>
<html>

   <head runat="server">
      <title>Ext.NET v2 Example</title>
   </head>

   <body>
      <ext:ResourceManager runat="server" />
      <ext:Button runat="server" Text="Apply defautls" OnDirectClick="ApplyDefaults" />
      <ext:UserControlLoader ID="UserControlLoader1" runat="server" Path="TestUC.ascx" />
   </body>
</html>

    Example User Control
    <%@ Control Language="C#" ClassName="TestUC" %>
   <script runat="server">
      public void ApplyDefaults()
      {
         this.Label1.Text = "Hello!";
      }
   </script>
   <ext:Label ID="Label1" runat="server" />
    My User Control CRTS/urGeneralControl.ascx
    <%@ Control Language="C#" AutoEVentWireup="true" CodeFile="urGeneralControl.ascx.cs" Inherits="CRTS_urGneralControl" %>

<ext:Label ID="Label1" runat="server" />
    My User Control CRTS/urGeneralControl.ascx.cs
    public partial class CRTS_urGeneralControl : system.Web.UI.UserControl
{
      public void ApplyDefaults()
      {
         this.Label1.Text = "Hello!";
      }
}
    I can't figure how to call my UserControl without the definition of ClassName.

    I think you should use this class "CRTS_urGeneralControl".

    That makes perfect sense. Please close the thread. Hopefully I can provide harder questions in the future and not these 1st grade questions.
