Question

I have a custom user control DatePicker.cs. Inside of another piece of code I have a collection of controls where I am checking the type of the control and doing some logic based on the type. My problem is the following:

typeof(DatePicker)

Evalutes to:

{Name = "DatePicker" FullName = "cusitecore.cedarsc.UserControls.DatePicker"}

But when I run the debugger and look at the type of the control that is on my web form it is:

{Name = "cedarsc_usercontrols_datepicker_ascx" FullName = "ASP.cedarsc_usercontrols_datepicker_ascx"}

These two things aren’t equal so the correct logic isn’t getting evaluated. I’ve tried using Type.GetType(“ASP.cedarsc_usercontrols_datepicker_ascx”) but this returns null.

EDIT

Here’s what I’m trying to do:

private readonly Dictionary<Type, ControlType?> _controlTypes = new Dictionary<Type, ControlType?>
    {
        {typeof(CheckBox), ControlType.CheckBox},
        {typeof(CheckBoxList), ControlType.CheckBoxList},
        {typeof(DropDownList), ControlType.DropDownList},
        {typeof(HiddenField), ControlType.HiddenField},
        {typeof(ListBox), ControlType.ListBox},
        {typeof(RadioButton), ControlType.RadioButton},
        {typeof(RadioButtonList), ControlType.RadioButtonList},
        {typeof(TextBox), ControlType.TextBox},
        {typeof(Label), ControlType.Label},
        {typeof(DatePicker), ControlType.DatePicker},
        {typeof(CustomSelect), ControlType.CustomSelect}
    };

private void PopulateFields(Control control)
{
    ControlType? controlType;
    _controlTypes.TryGetValue(control.GetType(), out controlType);

    // recurse over the children
    if (control.Controls.Count > 0 && controlType == null) // don't want to recurse into children of controls we are reading values of
    {
        foreach(Control childControl in control.Controls)
        {
            PopulateFields(childControl);
        }
    }

    if (controlType != null)
    {
        switch (controlType)
        {
            case ControlType.CheckBox:
            case ControlType.RadioButton:
                CheckBox checkBox = control as CheckBox;
                    if (checkBox != null)
                        _fields.AddFieldValue(checkBox.ID, checkBox.Checked ? "Checked" : "Not Checked");
                    break;
            case ControlType.CheckBoxList:
            case ControlType.ListBox:
            case ControlType.RadioButtonList:
                ListControl listControl = control as ListControl;
                if (listControl != null)
                    _fields.AddFieldValue(listControl.ID, String.Join(", ", listControl.Items.Cast<ListItem>().Where(item => item.Selected).Select(item => item.Value).ToArray()));
                break;
            case ControlType.DropDownList:
                DropDownList dropDownList = control as DropDownList;
                if (dropDownList != null)
                    _fields.AddFieldValue(dropDownList.ID, dropDownList.SelectedValue);
                break;
            case ControlType.HiddenField:
                HiddenField hiddenField = control as HiddenField;
                if (hiddenField != null)
                    _fields.AddFieldValue(hiddenField.ID, hiddenField.Value);
                break;
            case ControlType.TextBox:
                TextBox textBox = control as TextBox;
                if (textBox != null)
                    _fields.AddFieldValue(textBox.ID, textBox.Text);
                break;
            case ControlType.DatePicker:
                DatePicker datePicker = control as DatePicker;
                if (datePicker != null)
                    _fields.AddFieldValue(datePicker.ID, datePicker.Text);
                break;
            case ControlType.CustomSelect:
                CustomSelect customSelect = control as CustomSelect;
                if(customSelect != null)
                    _fields.AddFieldValue(customSelect.ID, customSelect.SelectedValue);
                break;
            case ControlType.Label:
                Label label = control as Label;
                if(label != null)
                    _fields.AddFieldLabel(label.AssociatedControlID, label.Text);
                break;
            default:
                throw new Exception("Unhandled Control");
        }
    }
}

ASP.NET creates it’s own type inherited from user controls.

For comparisons use the is operator.
For extractions use control.GetType().BaseType.
