How to build a GridView dynamically?

Hello everybody,
I'm fairly new to ASP.NET, so I'm turning to you for help.  Here's what I'm looking for.

I need to dynamically build a GridView on the page.  The database that I'm working with is Oracle10.  I need to pass the name of the Table in Oracle and the page would build a GridView control that would be populated with data from that table.  Every column should be sortable.  Every record would need to have the Delete option only.  When the user clicks on Delete link, a message box should come up with confirmation ("Are you sure you want to delete this record?").

Please provide either a code snippet on how it's done or point me to a source where I can find the code snippet.

This is very urgent and I appreciate any help you can provide.

Just to summarize.  I'm passing the name of the table and the GridView needs to be built with data and the Delete link next to each record.

Thanks.

This code may help:

(also have a look at: http://aspalliance.com/757_Code_Snip_Populating_GridView_Control_Using_ASPNET_and_C_with_MouseOver_Effect.2)
using System.Data;
using System.Data.OracleClient;
OracleConnection connection = new OracleConnection("MyConnectionString");
OracleCommand command = new OracleCommand();
OracleDataAdapter adapter = new OracleDataAdapter(command);
// With...
DataSet ds = new DataSet();
adapter.fill(ds);
connection.Close();
GridView1.DataSource = ds;
GridView1.DataBind();

Open in new window

First - For Sortable GridView1 - when you bind the code [mortaza has provided the code for it], use the DataView method and bind the data to the Cache too. Something like this:

ds = New DataSet()
adapter.Fill(ds, [TableName])

dv = New DataView(ds.Tables(TableName))
Cache(DataStore) = dv
GridView1.DataSource = dv
GridView1.DataBind()

Then call it in GridView_Sorting event:

Protected Sub GridView1_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles GridView1.Sorting

dv= Cache(Data)
dv.Sort = e.SortExpression.ToString()
GridView1.DataSource = dv
GridView1.DataBind()
End Sub

============

Second- for Delete button in every record and confirmation on GridView1:

In the Source code where the GridView1 is defined:

<asp:TemplateField ShowHeader="False">
<ItemTemplate>
  <asp:LinkButton ID="linkBtn" runat="server" CausesValidation="False" CommandName="Delete"
                 OnClientClick='return confirm("Are you sure you want to delete this entry?");'
                 Text="Delete" />
</ItemTemplate>
</asp:TemplateField>
