Hi

I want to place a MaskedEdit TextBox in a FormView InsertTemplate:

<asp:FormView ID="FormView1" runat="server" AllowPaging="True">

<InsertItemTemplate>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<table>

<asp:TextBox ID="TxtBox4" runat="server"></asp:TextBox>

<br />

<br />

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

runat="server"

TargetControlID="txtBox4"

MaskType=None

OnFocusCssClass="MaskedEditFocus"

OnInvalidCssClass="MaskedEditError" />

</td>

</tr>

</table>

</InsertItemTemplate>

 Where Should I place the scriptmanager?

The following Error occurs:

Hi There,

You only need 1 script manager in a page.

Place your script manager before any control that require it.

For me, i usually place it after the form tag. This is because all your control has to be within form tag.

example:

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
