Question

(VS 2010 C# Website) I have TextBox1 to filter FirstNames in a SQL database that will be displayed in a Datagrid, but I can’t figure out the proper way to link the user input from the “TextBox1.Text” into the WHERE clause for the Datagrid filtering. I’ve tried:

SelectCommand="SELECT * FROM [TestName] WHERE ([TestFirstName] LIKE '%' + TextBox1.Text + '%')"

Answer 1

SelectCommand="SELECT * FROM [TestName] WHERE ([TestFirstName] LIKE '%' + @TestFirstName2 + '%')">
    <SelectParameters>
        <asp:ControlParameter ControlID="TextBox1" Name="TestFirstName2" 
            PropertyName="Text" Type="String" />
    </SelectParameters>
