You'll either need to fix the webservice to work fully with unicode or you'll need to convert the string retrieved from the database into an encoding your webservice can work with.

Take a look at the various encoding classes under System.Text.

Migrating ASP to ASP.Net 2.0

Hi,

We are migrating an ASP application to ASP.Net 2.0. As It takes long time to develop complete .Net application, We want to add .Net pages what ever we develop into existing ASP application. Here I confused, like how to do it. Do we need to add .net pages to ASP application or ASP pages to .Net application. We are using Master Pages and AJAX controls, update panels in my .Net application, We are using div menu in asp application. I tried to add .net pages to existing asp application, its giving lot of errors like master page not exits and update panel not identified etc.

Please help me in resolving this.

Thanks,
Satheesh M

You're going to rewrite the entire application, that's about all there is to it. I would start a new project, and then migrate one page at a time. Well, in fact, it would be better to not migrate at all, b/c you will fail to use ASP.NET properly if you're focused on the minutae of each asp page. I'd just plan the whole thing again, as an ASP.NET app, and write it.

Yes, you are rite. But my client wants to go page by page. Yes I started a new project, added one MasterPage and Content page called Statement.aspx. Now I want to add this Statement.aspx to in existing ASP application Menu (Div Menu). I changed the menu link to navigate to Statement.aspx and I copied the Statement.aspx and Statement.aspx.vb files to ASP application directory. It asked me for Master file, than I copied Master page and the required dlls also. Its giving me error "Object reference not set to an instance of an object. " in the statment "Private connString As String = ConfigurationManager.AppSettings("sqlConn").ToString".

Your client is an idiot. It's not wrong to politely tell them so.

you're in way over your depth. Tell your client you have no idea what you're doing, and a complete rewrite is the only way you're likely to cope with this task.

Short version, you cannot just copy aspx files into an asp project, you need the web.config, etc. It still will plain not work, you won't be sharing session data for a start. It's a mess.

What error messages are you getting?
Have you stepped through your code?
Have you populated the gridview with data?

May be change your code like this

int i = 0;
while (i < grdViewpapers.Rows.Count)
{
CheckBox cbCelda = (CheckBox)grdViewpapers.Rows[i].FindControl("chkassignpaper");
if(cbCelda != null)
{
if (cbCelda.Checked)
{
Response.Write("hi" + i);
}
}
i++;
}
