Unable to cast object of type System.Web.UI.WebControls.GridViewRow to type System.Web.UI.WebCont

Hi Rohit,

Below way you will get the selected item and value of the dropdown.

Dim ddllist As DropDownList = DirectCast(sender, DropDownList)
Dim ddltype As DropDownList = TryCast(ddllist.NamingContainer.FindControl("cmbShowName"), DropDownList)
Dim selectedText As String = ddltype.SelectedItem.Text
Dim selectedValue As String = ddltype.SelectedValue

 Or simply change from

Dim item As DataGridItem = DirectCast(cell.Parent, DataGridItem)

to

Dim item As GridViewRow = DirectCast(cell.Parent, GridViewRow)
