Hi,

I have change it to ajaxToolkit:ToolkitScriptManager but still the same, it does not fire. But when i call the webservice on page load it is okay:

protected void Page_Load(object sender, EventArgs e)
{
FileService fService = new FileService();
string[] st = fService.GetSuggestions("s", 1);
}

Solution 2

The most convenient way to use autoCompleteextender with textbox is to right click on the textbox and add extender.From the Dialog Choose the AutoCompleteExtender and Ok.
Then Again right click and say ADD AutoCompletePageMethod.A Function will automatically be added to the.cs file.Add the desired code and see it runs...................
