Get ASPX control value in ASCX page

Hello,

To achieve this scenario, you have to first define public property in aspx page like this.

public DropDownList AffinityGroupDDL
        {
            get
            {
                return ddlAffinityGroup;
            }
        }

After that you can access your page controls like below

var dropDownList = ((StMainDashboard)Page).AffinityGroupDDL;

Try this.
