Sometimes I get this "error" (It just shows up in my screen, but the ddl's are still working) when I select an item in my Dropdownlist. Most of the time it doesn't though. Anyone has had this problem before?
Code:
private Sub VeranderBrouwer(obj as OBject, e as Eventargs)
dim i,j as integer
'get Brouwer-ID of other table
i=ddlBier.SelectedIndex
ddlBierBrouwer.SelectedIndex = i
j = ddlBierBrouwer.SelectedItem.Value
'select item with right Brouwer-ID
ddlBrouwers.clearselection()
ddlBrouwers.Items.findbyvalue(j).selected = true
end sub
...
<TD colSpan="5"><asp:dropdownlist id="ddlBier" runat="server" Width="200px" AutoPostBack="True" DataValueField="bier_id" DataTextField="naam" OnSelectedIndexChanged="VeranderBrouwer" tabIndex="3"></asp:dropdownlist></TD>
<TD colSpan="7"><asp:dropdownlist id="ddlBierBrouwer" Visible="False" runat="server" Width="10px" DataValueField="brouwer_id"></asp:dropdownlist></TD>
