I'm handling exceptions in the Application_Error() method in Global.asax but ex.Source is not giving me much. I want to know where the error occured i.e. /folderName/pageName.aspx.
Also I use lots of user controls so getting aspx name may not even be enough. Is there a way to get the name of object where the exception occured i.e. class name, user control name, etc.
one of the sites hosted on our server is giving this error in event viewer

I have ObjectDataSource and GridView on one of the pages of my asp.net web project.
To initialize ObjectDataSource i use Init event:
protected void ObjectDataSource1_Init(object sender, EventArgs e)
{
ObjectDataSource1.EnablePaging = true;
ObjectDataSource1.TypeName = "CustomerDataSource";
ObjectDataSource1.DataObjectTypeName = "Customer";
ObjectDataSource1.SelectMethod = "GetCustomers";
ObjectDataSource1.UpdateMethod = "Update";
ObjectDataSource1.SelectCountMethod = "GetCustomersCount";
ObjectDataSource1.MaximumRowsParameterName = "maximumRows";
ObjectDataSource1.StartRowIndexParameterName = "startRowIndex";
}
Somewhere in DAL:
public static List<Customer> GetCustomers(int maximumRows, int startRowIndex)
{
try {
... some select to database here...
}
catch (Exception ex)
{
Utils.LogError(ex);
throw ex;
}
}
Now let's imagine that GetCustomers for some reason throws an exception. How could i catch this exception and handle it? I know i can use Application_Error, but i would like to catch this exception somehow on my page and show some friendly message to the user.
