Question

I’m trying to populate the ASP.NET LISTVIEW with Stored Procedure(@param1). Could anyone please let me know if it’s possible at all. If it’s possible, if show me few lines of code will be very helpful.

See the Data Points: Data Source Controls in ASP.NET 2.0 article on MSDN which nicely shows how to use the SqlDataSource in your web app to provide data to data-capable controls.

Basically, you need a SqlDataSource

<asp:SqlDataSource ID="sdsYourData" Runat="server"
    ProviderName="System.Data.SqlClient"
    ConnectionString="Server=(local);Database=Northwind;Integrated Security=SSPI;"
    SelectCommand="dbo.YourStoredProcName" 
    <SelectParameters>
        <asp:Parameter Name="Param1" Type="String" />>
     </SelectParameters>
</asp:SqlDataSource>

that defines where to connect to to get your data (to your stored proc) – here, you’ll need to determine how to fill that parameter – in code? From another control on your ASP.NET page? Depending on that, you might use other elements into <SelectParameters>.

Once you have the data source, you can connect your list view to it:

<asp:ListView id="listView1" runat="server"
              DataSourceID="sdsYourData"
              DataTextField="SomeTextField" 
              DataValueField="YourIDField" />

Here, you need to set two fields:

• which of the columns from your SQL stored procedure will be used to display in the list view (DataTextField)?
• which of the columns from your SQL stored procedure will provide the value back to ASP.NET when that row in the listview is selected (DataValueField)?
