Question

May I know how could I pass the value of driver from code behind and throw into the query in aspx file ?

Here is my aspx part:

<asp:SqlDataSource ID="cs_sc" runat="server" 
ConnectionString="<%$ ConnectionStrings:MIMConnectionString %>"
SelectCommand="SELECT * FROM [Cash_Sales] WHERE [driver] = @driver">
<SelectParameters>
    <asp:Parameter Name="driver" Direction="Input" Type="String" />
</SelectParameters></asp:SqlDataSource>

code behind:

protected void Button1_Click(object sender, EventArgs e)
{
    driver = driverUpdateBox.SelectedItem.Text;
}

Answer 1

cs_sc.SelectParameters["driver"].DefaultValue = driverUpdateBox.SelectedItem.Text;
