Hi,

On the selected Index change event of the dropdown in user control, add below code.

C#

DropDownList ddlParent = (DropDownList)this.Parent.FindControl("dropdownlist1");
// dropdownlist1 ID of parent dropdownlist
if(ddlParent != null)
{
  //bind the dropdown list
}

hope it helps.

try this.

ddl.Items.Clear();
foreach(DataRow row in dt.Rows)
{
ddl.Items.Add(row["Text"].ToString(),row["Value"].ToString());
}
//Text and Value are the columns in datatable for text and value fields of the dropdownlist
