Hi,
I have a page with a calendar and two datalist items - one containing
month values and the other, year values. Depending on the month/year
value chosen ( in text/string format ) I should be able to display
the correct month of the calendar.
I thought it would be possible to use the OnSelectedIndex Changed
attribute of the dropdown list to call a javascript function that sets
the month value of the calendar...Some thing like :
<asp:DropDownLi st ID="MonthList" runat="server" AutoPostBack="T rue"
DataSourceID="A uctionMonthData Source" OnSelectedIndex Changed=getcal( )
</asp:DropDownLis t>
But how do I get access to the SelectedDate tag from inside getcal() ?
And do I have to manually convert the text values of the month into
numeric values ?
Thanks !
<asp:DropDownLi st id="ddlMonth" style="Z-INDEX: 101; LEFT: 64px;
POSITION: absolute; TOP: 24px" runat="server"
AutoPostBack="T rue"></asp:DropDownLis t>
<asp:Label id="Label1" style="Z-INDEX: 103; LEFT: 8px; POSITION:
absolute; TOP: 24px" runat="server"> Month</asp:Label>
<asp:DropDownLi st id="ddlYear" style="Z-INDEX: 102; LEFT: 200px;
POSITION: absolute; TOP: 24px" runat="server"
AutoPostBack="T rue"></asp:DropDownLis t>
<asp:Label id="Label2" style="Z-INDEX: 104; LEFT: 152px; POSITION:
absolute; TOP: 24px" runat="server"> Year</asp:Label>
<asp:Calendar id="Calendar1" style="Z-INDEX: 105; LEFT: 16px;
POSITION: absolute; TOP: 72px" runat="server"> </asp:Calendar>
