When i run the code and click the calendar near "txtTermin" the calendar is displayed,but when i change the date in calendar it was not changed in textbox (txtTermin).
But when I replace
<obout1:OboutTextBox runat="server" ID="txtTermin" Width="150" />
with
<asp:TextBox runat="server" ID="txtTermin" Width="150" />
everything is working OK.
Of course the same problem is with txtDataW.
Please help, why calendar doesn't work with OboutTextBox,but works with standard ASP TextBox ? In this example : http://www.obout.com/grid/grid_commands_row_template.aspx it works (Order Date,Required Date..) with OboutTextBox'es.
