Question

Hi I’m building a web application for a client with some unique controls and criteria. One page involves a detailed search function consisting of about 100 combo boxes and listboxes. What I am trying to do is do a foreach(control that has been changed/selected){} and feed it into a function to generate a query. There are 100 but the user may only use three for a particular search ?

I know there must be a way to do this. Thanks in advance for the help

Well you can use something like:

List<Control> list = new List<Control>();

public void ControlRecursive(Control Root)
    {
        if(typeof(ComboBox) == Root.GetType() && ((ComboBox)Root).Checked)
            list.Add(Root);
        else if (Root is RadListBox)
        {
            // deal with RadListBox here
        }
        // if all your other types
        // ...

        foreach (Control Ctl in Root.Controls)
            ControlRecursive(Ctl);
    }

Then call this with ControlRecursive(form1);
