Dynamically add checkboxlist into placeholder and get the checked value of the checkboxlist

I am creating an admin Page, in which checkboxlist(User list from DB)is to be created dynamically and its the checked users value is retrieved.

There are different types of users, so it is distinguised groupwise.

Now first a panel is defined, the checkboxlist is created dynamically and placed inside the panel, then the panel is placed inside a Placeholder.

What Iam doing here is placing the checkboxlist inside the panel, then the panel inside the placeholder. So the values of the Checkboxlist is not retrieved, due to the panel it doesnt get the checkboxlist and it doesn't loop through the Checkboxlist.

What I have done is.

                }
            }
        }
        return sbtext.ToString();        }

It doesnt get through the Checkboxlist control in the setChecked(), also doesnt loop through the GetListCheckBoxTest().

Anyone can plz help me.

The problem is that you are trying to find a control (in setChecked) without setting the Name property. You are using this:

CheckBoxList chkList = (CheckBoxList)Place.FindControl("ChkUser");

But where is this in AddControl?

chkList.Name = "ChkUser";

And in GetListCheckBoxText instead of...

if (c.GetType().Name == "CheckBoxList")

...use this:

if (c.GetType()== typeof(CheckBoxList))
