Need help with ODBC parameters in asp.net and Datagrid

I have in issue in asp.net that I need help with. My Datagrid is using an ODBC connection to a Sybase DB and my query has 4 parameters, two of which are in a LIKE clause:
WHERE 
    vhs.SALES_INV IS NOT NULL 
	AND (vhs.SALESDATE >= ? AND vhs.SALESDATE <= ?) 
	AND (vhs.MAKE LIKE ?) AND (vhs.Model LIKE ?)"

<SelectParameters>
    <asp:ControlParameter Name="FromDate" 
      ControlID="rdFromDate"
      Type="DateTime" PropertyName="SelectedDate"/>
    <asp:ControlParameter Name="ToDate" 
      ControlID="rdToDate"
      Type="DateTime" PropertyName="SelectedDate"/>
    <asp:ControlParameter Name="Make" 
      ControlID="rtMake"
      Type="string" PropertyName="Text"/>
    <asp:ControlParameter Name="Model" 
      ControlID="rtModel"
      Type="string" PropertyName="Text"/>
</SelectParameters>
</asp:SqlDataSource>

Open in new window


I cant figure out how to pass the text variables in the query by appending for example '%" + rtMake + "%'  or similar to make the LIKE function work correctly. Everything I do results in a "Server Tag not Well Formed".

Any ideas? Thanks in advance

You can use the SqlDataSource.Selecting event to change the value of the parameters.

Thanks Louis! That worked. For anyone else needing a code behind sample it is here:

<code>
protected void DATASOURCE_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
        {
            e.Command.Parameters[2].Value = "%" + rtMake.Text + "%";
            e.Command.Parameters[3].Value = "%" + rtModel.Text + "%";

        }
