What if you would need to validate date time control in a visual web part ? Yes , its very simple. You need to use compare validator to validate the SharePoint date time control. The code is given below.
<sharePoint:DateTimeControl ID="dteJoining" runat="server" DateOnly="true" />
<asp:CompareValidator id="validateDate" runat="server"
ControlToValidate="dteJoining$dteJoiningDate"
Type="Date" Operator="DataTypeCheck" ErrorMessage="Please enter an valid date"> </asp:CompareValidator >
The following properties can be validated against
•DateOnly
•IsRequiredField
•MinDate
•MaxDate
Happy Share Pointing :-)
