Hello,

I want to insert values from a dropdownlist and textbox into a table. The
textbox may be visible only if the selectedvalue of the ddl is "2".
My problem is that i need to click two times on the button before the values
are inserted in the table. I put a response.write to check the value: after
the first click, nothing appears, after the second, they appear and are
inserted.

Why is that?
Thanks
Theo

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack=true  >
<asp:ListItem Text="x" Value="1"></asp:ListItem>
<asp:ListItem  Text="y" Value="2"></asp:ListItem>
</asp:DropDownList>
<br /> <br />
<asp:TextBox ID="TextBox1" runat="server" Visible="false"
AutoPostBack=true></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="save" />
