Hi all,
 
not sure how often this question has been answered, if at all. 
 
I have written a webcustomcontrol (NOT ascx). 

I have 10 on a web page and want to find them  in the code behind.

I have tried using foreach, but I am not sure what  collection to search in. 

Does anyone know the answer to this question? Is it possible?

Thanks in advance,

foreach (Control c in this.Controls)
{
if (c.GetType() == typeof(YourControl))
{
Response.Write(c.Name);
}
}

I get this error:

Object does not match target type.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Reflection.TargetException: Object does not match target type.

Source Error: 

Line 71: 						if(y.Name == "EditMode")
Line 72: 						{
Line 73: 							y.SetValue("EditMode", bEdit, null);
Line 74: 						}
Line 75: 					}

Source File: d:\www\smdtest\default.aspx.cs    Line: 73
 
From this code:
 


Type t;


foreach (Control oPart in this.Controls)


{


t = typeof(SMDCMS.WebPart);


if (t.FullName.IndexOf("WebPart")>0)


{


PropertyInfo[] p = t.GetProperties();


foreach(PropertyInfo y in p)


{


if(y.Name == "EditMode")


{


y.SetValue("EditMode", bEdit, null);


}


}


}


}
 
Please help!!

much more compact and doesn't use reflection (NEVER use reflection in a loop like that just to set properties - it is as slow as hell). Just use boxing to convert the type



foreach (Control oPart in this.Controls)

{

    if (oPart.GetType() == typeof(SMDCMS.WebPart))

    {

        SMDCMS.WebPart webPart = oPart as SMDCMS.WebPart;



        webPart.EditMode = true;

    }

}
