Hi All , I have a problem with reading a Clicked Date from a Pop-Up Calendar. I have the button and a Text Box in a WebForm.Clicking this button pops up a calendar(which is a separate WebForm). Selecting a Date on the WebForm transfers the selected Date to the Text Box(on the Other WebForm). In the "Code Behind" for the Calendar WebForm I have the following Code:: Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Put user code to initialize the page here 'THE FOLLOWING LINE GIVES ME AN ERROR -- IT SAYS THAT 'System.NullReferenceException: Object reference not set to an instance of an object. Hidden1.Value = Request.QueryString("textbox").ToString() End Sub Public Sub Calendar1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim strScript As String = "<script>window.opener.document.forms(0)." + Hidden1.Value + ".value = '" strScript += Calendar1.SelectedDate.ToString("MM/dd/yyyy") strScript += "';self.close()" strScript += "</" + "script>" RegisterClientScriptBlock("anything", strScript) End Sub iN THE paGE WHERE THE BUTTON IS CLICKED I HAVE THE FOLLOWING CODE IN THE html PART <INPUT name="textBox1" type="text" id="textbox1"> <INPUT type="button" runat="server" onclick="javascript:cal=window.open('Calender.aspx?textbox = textbox1','cal','width=800,height=800' );cal.setfocus()" value="Button" /> nOW WHAT IS THE WAY OUT? HELP IS GREATLY APPRECIATED.tHANKS ,
