Could not load type 'UserWebControl.DatePicker'.

[Stephan]

Hi all,

when trying to build a custom webcontrol I receive the above message.
It's caused by the inherits attribute of de the control-directive. I
have no clou of what could be going wrong. Any help is appreciated:

Code of the control:

<%@ Control Language="vb" AutoEventWireup="false"
Codebehind="control_DatePicker.aspx.vb"
inherits="UserWebControl.DatePicker"%>
<table cellpadding="0" cellspacing="2" border="0">
<tr>
<td align="right"><asp:TextBox id="tbxDatum" runat="server"
Width="92px" MaxLength="10"></asp:TextBox></td>
<td align="middle">
<asp:ImageButton id="ImageButton1" runat="server"
ImageUrl="images/cal.gif"></asp:ImageButton></td>
</tr>
<tr>
<td colspan="2" height="0px">
<aspanel id="cal1" runat="server" style="CLEAR: none; DISPLAY:
block; FLOAT: left; OVERFLOW: visible; POSITION: absolute"
Visible="False">
<asp:Calendar id="calendar1" runat="server" Width="200px"
BackColor="White" DayNameFormat="FirstLetter" ForeColor="Black"
Height="180px" Font-Size="8pt" Font-Names="Verdana"
BorderColor="#999999" CellPadding="4">
<TodayDayStyle ForeColor="Black"
BackColor="#CCCCCC"></TodayDayStyle>
<SelectorStyle BackColor="#CCCCCC"></SelectorStyle>
<NextPrevStyle VerticalAlign="Bottom"></NextPrevStyle>
<DayHeaderStyle Font-Size="7pt" Font-Bold="True"
BackColor="#CCCCCC"></DayHeaderStyle>
<SelectedDayStyle Font-Bold="True" ForeColor="White"
BackColor="#666666"></SelectedDayStyle>
<TitleStyle Font-Bold="True" BorderColor="Black"
BackColor="#999999"></TitleStyle>
<WeekendDayStyle BackColor="#FFFFCC"></WeekendDayStyle>
<OtherMonthDayStyle ForeColor="#808080"></OtherMonthDayStyle>
</asp:Calendar>
</aspanel></td>
</tr>
</table>

Sorry,

but I didn't include de projectname. The problem is solved. In my case
the control-directive should look like this:

<%@ Control Language="vb" AutoEventWireup="false"
Codebehind="control_DatePicker.aspx.vb"
inherits="{projectname}.UserWebControl.DatePicker"%>

Thx
