Hi guys,

I need some help with showing an array in a aspx web page...

I want to post the results on to a web page. ....Could you please show me how to do these with a sample or resources....

 May be by writing strings of html with Response.Write

or

or using ASP.NET's Table and TableRow control

I dont know which one is better...or how to go about it..

i have this iteration in my code behind....

 wservices.NServices service = new wservices.NServices();

        Event[] eventArray = service.Get(222, null, null, null, null, new DateTime(2007, 4, 1), null,         33, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null,         null, null);

int i;
        for (i = 0; i < eventArray.Length; i++)
        {

            Object obj = eventArray[i];
         
        }

You might try converting the array to an arraylist .. Then simply bindng the arraylist to a gridview.
In your HTML put  Gridview control and then in code behind.
ArrayList eventArrayList= ArrayList.Adapter(eventArray);
Gridview1.Datasource = eventArrayList;
Gridview1.Databind().

Thanks! That seems to work after i added using System.Collections;  but i still get an error..

The name 'Gridview1' does not exist in the current context      

any idea why? I added the gridview to the aspx page...

1. doublecheck name  Gridview1 (c# is case sensitive).
2. check you have the runat=server in the html (ie <asp:Gridview id="grid" runat="server"..
If none of the above work. please post your html .

 <asp:GridView ID="GridView1" runat="server" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" Width="348px">
                </asp:GridView>

When are you getting the error regarding context, when trying to bind to the grid?

Sorry to be a pain, however c# is case sensitive
in your above post :   Gridview1.Datasource = eventArrayList;  the v in Gridview is not with a capital v
and in your html example  <asp:GridView ID="GridView1" runat="server" OnSelectedIndexChanged ..
it is.

Try    GridView1.Datasource   .
