ASP.Net multiple textbox controllers for a table - mysql

Question

I am making a web application and have a webform connected to an access database table. For one of my queries I have a table with supplier info and I need to filter the results by name, city, and type.
I used the query builder to have the parameters input by the user through 3 textboxes (one for each parameter). When I run the query in the query builder the results come up fine, but when I run it through a browser it fails (the form shows up fine, but it's not taking the input parameters in the textbox to populate the table). I made sure I linked the parameters to the texbox control through the wizard.
I've built forms with a single input parameter controlled with a single textbox and those have worked just fine, but when I used multiple parameters and textboxes it doesn't work in the browser.
I appreciate any help! Thanks!

Make sure you bind control with parameter.
<SelectParameters>
<asp:ControlParameter Name="Comments" PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="txtLastName" Name="Title" PropertyName="Text" Type="String" />
</SelectParameters>
You can pass parameters runtime as below.
<SelectParameters>
<asp:Parameter Name="Comments" Type="String" />
<asp:Parameter Name="Title" Type="String" />
</SelectParameters>
protected void AccessDataSource1_Selecting(object sender, System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs e)
{
if (txtFirstName.Text.Length > 0 && txtLastName.Text.Length > 0)
{
e.Command.Parameters["parameter1"].Value = txtFirstName.Text;
e.Command.Parameters["parameter2"].Value = txtLastName.Text;
}
}
