Question

• i have 2 dropdown lists, 1 label & 1 textbox.

• on selection of ‘product categories’ @ 1st ddl, 2nd ddl displays all product categories.

• question is, how may i display the product category id @ the label, and name @ the textbox, on load/selection of 2nd ddl?

• i have the following code:

 

Public Sub FilterProductCategory()
    Dim myConn As New SqlConnection
    Dim myCmd As New SqlCommand
    Dim dtrReader As SqlDataReader


    myConn.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
    myCmd = myConn.CreateCommand
    myCmd.CommandText = "SELECT product_category_id, product_category_name FROM ProductCategory ORDER BY product_category_name"

    Try
        myConn.Open()
        dtrReader = myCmd.ExecuteReader()

        If dtrReader.HasRows Then
            DropDownList2.Items.Clear()
            DropDownList2.DataSource = dtrReader
            DropDownList2.DataValueField = "product_category_name"
            DropDownList2.DataBind()
        End If
        dtrReader.Close()
        myConn.Close()
    Catch
    End Try
End Sub

Answer 1

just set this:

DropDownList2.DataTextField = "product_category_name"
DropDownList2.DataValueField = "product_category_id"

so when you try dropdownlist2.selectedvalue then you will get id and when u try dropdownlist2.selecteditem.text then it will give you product category name ..

hope it will solve your problem
