ASP .NET - How to refresh a databound DataList?

Question

I have a DataList that is bound to a SQlDataSource. The SQLDataSource returns a stored procedure value containing the max indentity value in a table.

On the same page as the DataList I have a DetailsView that is used to add new records to the table.

The problem is that after adding a new record to the table the Datalist value shows the previous indentity value.

How do I have the page automatically refresh the DataList?

Answer 1

Call DataList.DataBind() in either the page load method or the ItemInserted method of the Details View.

For example:

void YourDetailsView_ItemInserted(object sender, 
DetailsViewInsertedEventArgs e)
{
    // Refresh the DataList control after a new record is inserted 
    // in the DetailsView control.
    YourDataList.DataBind();
}

And in the markup:

<asp:DetailsView id="YourDetailsView" runat="server" 
DataSourceID="YourSQLDataSourceID" OnItemInserted="YourDetailsView_ItemInserted"/>
