liorlankri · December 5th, 2004, 10:45 AM

I have a button that click on it should do:

Private Sub Check_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Check.Click

        Dim strFirstName= Me.firstName.Text
        Dim strFamilyName= Me.familyName.Text
        Dim strYearArrive = Me.selectYear.SelectedValue

window.open('CheckStudet.aspx?firstName='+strFirst Name+
'&familyName=' +strFamilyName+ '&YearArrive =' +strYearArrive ,'Check','width=500,height=250,directories=no,loca tion=no,menubar=no,scrollbars=no,status=no,toolbar =no,resizable=no');

    End Sub

In fact I want to open saperate window. but my code is incorect!
How to do it?

window.open() is a javascript function. You need to create a javascript function in the <script> area of your HTML. Then call that function from your click event. In order to run both server side code and client side code from your code behind event, you need to use the Page.RegisterClientScriptBlock Method or the Page.RegisterStartupScript Method.

Another possibility,

Code:

private void Page_Load(object sender, System.EventArgs e)
{
    if(!Page.IsPostBack)
    {
           string s="";
           s+="window.open('URL','Description','');";
           Button.Attributes.Add("onclick",s);
    }
}
private void Button_Click(object sender, System.EventArgs e)
{
      //put codes execute on the server-side after opening new window
}
