Prototyping in ASP.Net - asp:SqlDataSource Example
Recently, I've been doing a bunch of ASP.Net. One of ASP.Net's best features is its ability to be used for realistic rapid prototyping.
Here is a simple example that executes a SQL query and displays the results.
In the aspx... (be sure and notice the "$" in the connection string)
<asp:sqldatasource id="SqlDSCoreCoverages" runat="server" connectionstring="<%$ ConnectionStrings:ConnectionString_DEV %>" >"
ProviderName="Oracle.DataAccess.Client"
SelectCommand="
select coverage_description, display_order
from prod_cov
whereid = :argProductVersionId
order by display_order
"
EnableCaching="True">
</asp:SqlDataSource>
<table cellpadding="3" style="border: 1px #333333 solid;">
<tr><td>
<asp:gridview id="GridView1" runat="server" datasourceid="SqlDSCoreCoverages" autogeneratecolumns="False" gridlines="None">
<headerstyle cssclass="SectionHeader">
<columns>
<asp:BoundField DataField="coverage_description" HeaderText="Included Core Coverages"
ReadOnly="True" SortExpression="coverage_description" />
</columns>
</asp:GridView>
</td></tr>
</table>
In the aspx.cs [codebehind] ...
this.SqlDSCoreCoverages.SelectParameters.Add("argProductVersionId", productVersionId.ToString());
this.SqlDSCoreCoverages.DataBind();

hey ur example helped a lott tanks.. hey how to check whether the retreived value fom database is empty using these statements can u help me out...
It's been a while since I looked at this code.
I think you can do something like...
protected void SqlDSCoreCoverages_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.AffectedRows == 0)
{
Response.Write("There are no records available");
}
}
Excelente informacion, lo que andaba buscando :):):):):):)
