EWorld Calender Control

[India777]

Hai all,
I am using EWorld DLL for Calender Control.
How i can Change the LowerBoundDate for End Date in Code Behind when i Select the Start Date, without Submitting Whole Page?


Sample Codes: .aspx page

<table>
<tr>
    <td align="right">PO Start Date : </td>
    <td align="left"><ew:calendarpopup id="cal_po_date" PopupLocation="Right" runat="server" Width="175" Nullable="true" 
    TextBoxLabelStyle-CssClass="textbox" ButtonStyle-Width="30" ButtonStyle-CssClass="DatePicImg01"
    ButtonStyle-BorderStyle="None" ButtonStyle-Height="22" AutoPostBack="true"></ew:calendarpopup>
    </td>
</tr>
<tr>
    <td align="right">PO End Date : </td>
    <td align="left"><ew:calendarpopup id="cal_po_end_date" PopupLocation="Right" runat="server" Width="175" Nullable="true" 
    TextBoxLabelStyle-CssClass="textbox" ButtonStyle-Width="30" ButtonStyle-CssClass="DatePicImg01"
    ButtonStyle-BorderStyle="None" ButtonStyle-Height="22" AutoPostBack="true"></ew:calendarpopup>
    </td>
</tr>
</table>

Sample Codes: .vb (DateChanged event for Start Date)

Protected Sub cal_po_date_DateChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cal_po_date.DateChanged
	Try
		cal_po_end_date.LowerBoundDate = DateAdd(DateInterval.Day, 1, cal_po_date.SelectedDate)            
	Catch ex As Exception
		ShowAlert(ex.Message)
	End Try
End Sub

The End Date's LowerBoundDate isn't Change when i Select the Start Date.

Thanks,
SR
