Bad news....

Ok, maybe you could have some ideas of how to resolve my issue...

I am using this code to print a UltraWebGrid:

--------------------------------------------------------------------------------------------------------------------------------------------------------

       void printButton_Click(object sender, EventArgs e)
        {
            _gridControl.Browser = Infragistics.WebUI.UltraWebGrid.BrowserLevel.DownLevel;
            _gridControl.DisplayLayout.ReadOnly = ReadOnly.PrintingFriendly;

            string script =
                        "<script language=javascript> " +
                         " var Grid = document.getElementById('" + _gridControl.ClientID + "'); " +
                        " var prtContent = document.getElementById('" + div.ClientID + "'); " +
                        " var WinPrint =  window.open('','','left=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status=0');  " +
                        " WinPrint.document.write(prtContent.innerHTML); " +
                        " WinPrint.document.close(); " +
                        " WinPrint.print(); " +
                        " WinPrint.close(); " +
                        "</script> ";

            this.Parent.Page.RegisterStartupScript("Script", script);

            _gridControl.Browser = Infragistics.WebUI.UltraWebGrid.BrowserLevel.Auto;
            _gridControl.DisplayLayout.ReadOnly = ReadOnly.NotSet;
        }

--------------------------------------------------------------------------------------------------------------------------------------------------------

the problem is that the Script is executed in other Event,

not as I hope in this line:  this.Parent.Page.RegisterStartupScript("Script", script);

that line only register the Javascript and the problem is that when the Script is called the properties of the Grid was reverted to:                         

            _gridControl.Browser = Infragistics.WebUI.UltraWebGrid.BrowserLevel.Auto;
            _gridControl.DisplayLayout.ReadOnly = ReadOnly.NotSet;

and  some javascript make my page to raise a JS error.

I see that you have this question posted in other threads, as well as a support case.

My best suggestion is to not try to render out the HTML of your page in this fashion.  This is likely to break a lot of functionality that WebGrid depends on, as well as other controls.

Hello,

There is a client-side object model (CSOM) for WebGrid documented here which you can use:

http://help.infragistics.com/Help/NetAdvantage/NET/2008.3/CLR3.5/html/WebGrid_Object_CSOM.html

You cannot set server-side properties with javascript unless you are doing AJAX or PostBack to the server.

Sorry for that....

 My best suggestion is to not try to render out the HTML of your page in this fashion.

 Do you know any other way?
