Hi,

I am working on C#, Asp.net 2.0
I have a user control with id WucMainPage1 and inside this control there is another control used with id WucPages1

I want to call a method fillPageType(); which is inside usercontrol WucPages1

How should I do it.

Please guide.

I am trying with various method:

      UserControl WucPages1 = (UserControl)WucMainPage1.FindControl("WucPages1");
//      Type myType = typeof(WucPages1);
//      MethodInfo myMethodInfo = myType.GetMethod("fillPageType");
//      myType.InvokeMember(function,BindingFlags.InvokeMethod, null, null, null);

      //WucPages1.LoadControl

      // WucPages1.fillPageType();
      //  WucPages1.BindPageGrid();
      
      
Thanks,

Assuming your UserControl is named "WucPages"...

WucPages WucPages1 = (WucPages)WucMainPage1.FindControl("WucPages1");
WucPages1.fillPageType();

Error Says:

Error      1      
The type or namespace name 'WucPages' could not be found (are you missing a using directive or an assembly reference?)


I have control where wucMainPage.ascx is registered. Inside wucMainPage.ascx control wucPages.ascx is registered.

Now in Page wucPages.ascx, I have method fillPageType(), which I wish to access from wucCourseContent.ascx.cs

Thanks


-- wucCourseContent.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="wucCourseContent.ascx.cs" Inherits="VW_Controls_wucCourseContent" %>
<%@ Register Src="wucMainPage.ascx" TagName="wucMainPage" TagPrefix="uc1" %>

                </asp:View>
               
    </asp:MultiView>
   
   
   
    -- wucMainPage.ascx


<%@ Control Language="C#" AutoEventWireup="true" CodeFile="wucMainPage.ascx.cs" Inherits="VW_Controls_wucMainPage" %>
<%@ Register Src="wucUploadImages.ascx" TagName="wucUploadImages" TagPrefix="uc1" %>

<div class="LnkBtndiv1"><asp:LinkButton ID="btnGlossary" runat="server" Text="Glossary" OnClick="btnGlossary_Click" /></div>
<div class="LnkBtndiv1"><asp:LinkButton ID="btnImages" runat="server" Text="Upload Images" OnClick="btnImages_Click" /></div>
<asp:HiddenField runat="server" ID="hdnTabClick" Value="1" />

<br clear="all" />
<asp:MultiView runat="server" ID="mvCourseManagement" ActiveViewIndex="0" OnActiveViewChanged="mvCourseManagement_ActiveViewChanged" >
      <asp:View ID="vwPages" runat="server">
            <uc3:wucPages ID="WucPages1" runat="server" />
      </asp:View>
      <asp:View ID="vwQuestion" runat="server">

        <uc1:wucUploadImages ID="WucUploadImages1" runat="server" />
            
      </asp:View>
</asp:MultiView>



Now Inside control file wucPages.ascx, I have a method


public void fillPageType()
{
      oTypeMstrBL = new TypeMstrBL();
      int iApplyLevel = 3;

      DataTable odt = oTypeMstrBL.GetCategoryListing(iApplyLevel);

      ddlPageType.DataSource = odt;
      ddlPageType.DataBind();

      ddlPageType.Items.Insert(0, new ListItem("-- Select Type --", ""));
}

In this case you'll have to declare a public property or method to expose the method in the inner control to the outer one.

You should also add the following reference:

-- wucCourseContent.ascx

<%@ Reference Control="wucPages.ascx"%>


/*** wucMainPage.ascx.cs ***/
 
public property ASP_WucPages WucPages1_1
{
  get { return WucPages1; }
}
 
 
/*** wucCourseContent.ascx.cs ***/
 
WucMainPage1.WucPages1_1.fillPageType();

Open in new window

The other option is to simply expose a method:
/*** wucMainPage.ascx.cs ***/
 
public void WucPages1_fillPageType()
{
  WucPages1.fillPageType();
}
 
 
/*** wucCourseContent.ascx.cs ***/
 
WucMainPage1.WucPages1_fillPageType();
