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");
}
}
}
CustomControl is a loosely coupled control w.r.t code and UI while UserControl is a tightly coupled control w.r.t code and UI. When using CustomControl UI can be changed in different projects but for a UserControl UI is fixed and can't have different looks in different project.
UserControl : A control which can reuse the Components in the Applications. The control can be defined in both Xaml and Code-Behind. CustomControl : An UserInterface element that have a distinct behavior which is said as CustomControl.
ASP.NET creates it's own type inherited from user controls.
For comparisons use the is
operator.
For extractions use control.GetType().BaseType
