hello all,

I am calling a date field from sql to datatable and showing in a combobox.

Then i am using the following code to check the users selection in combobox and use it to get a related row value from datatable.

While i try to convert the selected item in combobox to date again for comparing in datatable, the above error occurs.

Pls suggest the wayout.

I have marked the line with error

Thanks

VB

Private Sub ddlDate_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ddlDate.SelectedIndexChanged

*****        Dim expenddt As Date = Date.ParseExact(ddlDate.SelectedItem, "dd-MM-yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo)

        txtValue.Text = fnClosingvaluefromDatatable(expenddt)

    End Sub

Please use cdate(ddldate.selecteditem) for comparing dates.

VB

Private Sub ddlDate_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ddlDate.SelectedIndexChanged
        Dim expenddt As Date = Date.ParseExact(ddlDate.SelectedItem, "dd-MM-yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo)

        txtValue.Text = expenddt
        If Date.Today > CDate(ddlDate.SelectedItem) Then
            MsgBox("The current date is greater than of selected date")
        End If
    End Sub
