Dear All,

I am new to ajax calender control.

<asp:TextBox ID="txtActDate" runat="server" CssClass="textSmallmand"></asp:TextBox>
<ajax:CalendarExtender ID="calActDate" runat="server" TargetControlID="txtActDate" PopupButtonID="imgCal" Format="dd/mm/yyyy">
</ajax:CalendarExtender>
<asp:ImageButton ID="imgCal" runat="server" Height="19px" ImageUrl="~/date_picker2.gif" Width="34px" CausesValidation="False" />

the problem is all controls are displaying, but when i click the Imagebutton, the calander control is not displaying.

Can anyone help?

Use the following codes

   runat="server" enableviewstate="true"
   class="txtlostfocus1" type="text" style="font-weight: bolder; width: 119px;"
                                            tabindex="4" />

         Position="bottom" PopupControlID="Panel2">






                                                    BackColor="White" BorderColor="#999999" CellPadding="1" Font-Names="Verdana"
                            Font-Size="8pt" ForeColor="Black" OnSelectionChanged="Calendar2_SelectionChanged" >














       CODE BEHIND
       -----------
       protected void Calendar2_SelectionChanged(object sender, EventArgs e)
    {
        PopupControlExtender1.Commit(Calendar2.SelectedDate.ToShortDateString());
    }
