Force a changed event from a child window ?

[Adrian Parker]

We have a date control (textbox) that opens up a popup calendar window, how,
when that calendar returns with the selected value can I cause the changed
event to fire on the date control ?

Hello Adrian,

Regarding the issue, how did you open up a popup calendar window? Like
following?

<form id="form1" runat="server">

<asp:TextBox ID="TextBox1" runat="server" Height="29px"
Width="235px" onclick="window.open('calendar.aspx')"></asp:TextBox>
</form>

If you just implement as above, you may add following code in the
'calendar.aspx':

Protected Sub Calendar1_SelectionChanged(ByVal sender As Object, ByVal
e As System.EventArgs) Handles Calendar1.SelectionChanged

Dim SelectedDate As String = Calendar1.SelectedDate.ToString()

Dim scriptString As String = "<script language=JavaScript>
window.opener.document.form1.TextBox1.value='" + SelectedDate + "';
window.opener.document.form1.TextBox1.fireEvent('onchange');
window.close(); </script>"


ClientScript.RegisterClientScriptBlock(Type.GetType("System.String"), "",
scriptString)

End Sub

Above script will set the value of the Text Box in its parent windown and
then fire the "onchange" event on the TextBox.

Sincerely,

Luke Zhang
