Hello,
Is there a way to make a dataset global to all my aspx 2.0 web forms?
Thanks,
Chuck

Sure. Declare it in your Global.asax as a public static field. Then you can
refer to it from any page as Global.MyDataSet

Thanks,
For some reason is it not working for me.
This is the code:
<%@ Application Language="VB" %>
<script runat="server">
Public MyDataset As New Dataset
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs on application startup
End Sub
I Cannot put Public Static as an error is shown that says it is not a part
of a declaration.
When I type Global. - MyDataset is not listed.
Thanks,
Chuck

You could put it in Application State.
Application.Lock()
Application("MyDataSet") = MyDataSet
Application.Unlock()

Charles,
"static" is the C# modifier. in VB.NET, you want to use the equivalent
keyword, "Shared".

Hello,
I am not sure why this isn't working
<%@ Application Language="VB" %>
<script runat="server">
Public Shared ATest as string
OR
Public Shared MyDataset as New Dataset
In Default.aspx in the Load_Event
Global. does not show ATest or MyDataset
could there be a setting that I am missing?
Thanks

Hello,
This appears to let me see the dataset throughout my application, but when I
make changes to it, the changes to follow. IE
This is Page 1
Dim ARow as DataRow = Application("MyDataset").Tables(0).NewRow
ARow(0) = "Hello"
Application("MyDataset).Tables(0).Rows.Add(ARow)
This is Page 2
Datagrid1.DataSource = Application("MyDataset")
Datagrid1.Databind
Could I be loosing my data on the postback? Any Suggestions.
Page 2 shows an empty dataset without the row I added on page 1
Thanks,
Chuck

After you make changes to the DataSet you should put the new modified
version back into Application State using the same lines of code I already
gave you.

Declare it in a class in the APP_CODE folder with a public accessor.
But it does involve some code because your other pages will then
have to 'call it' from the class.
