Populating Control values from a Dictionary?
I am new to C# so please fogive my newbie question.
I created a dictionary of controls from a Windows form called dictControls. I then populated it with all text box and combobox controls and开发者_JS百科 values from the form:
Dictionary<Control, string> dictFormControls = new Dictionary<Control, string>();
foreach (Control c in Controls)
{
if (c is ComboBox)
{
dictFormControls.Add(c, ((ComboBox)c).SelectedValue.ToString());
}
if (c is TextBox)
{
dictFormControls.Add(c, ((TextBox)c).Text);
}
if (c is MaskedTextBox)
{
dictFormControls.Add(c, ((MaskedTextBox)c).Text);
}
}
if (discNumber <= Convert.ToInt32(numDiscs))
{
frmAddVideo frm = new frmAddVideo(numDiscs, discNumber, videoID, sequenceID, dictFormControls);
frm.Show();
this.Close();
}
I want the dictionary basically look something like this:
Key ------------ Value
"txtName" ----- "Test"
"txtYear" ------ "1980"
I am passing this back into the same form (frmAddVideo):
public frmAddVideo(string numDiscs, int discNumber, string videoID, string sequenceID, Dictionary<Control, string> dict)
{
this.numDiscs = numDiscs;
this.discNumber = discNumber;
this.videoID = videoID;
this.sequenceID = sequenceID;
InitializeComponent();
//This is where I want to parse out the Dictionary and populate the form values
foreach (KeyValuePair<Control, string> item in dict)
{
**Basically, I am looking for a way to take **
**item(Key)**
**and do something like item(Key).Value = item(Value);**
**so it would be the same as writing**
**txtName.Text= "1980";**
**cbxLocID.Value = 1;**
}
}
I am looking for a way to take key and turn it into the control name, then add ".Text" or ".Value" to it and then set the value to item(value) as I explained in the code above.
Is this possible? I tried researching this, but I have yet to put 2 and 2 together.
You may just store the set of controls you work with in your dictionary:
class ControlBoundValueDescription
{
private Control _control;
public ControlBoundValueDescription(Control control)
{
_control = control;
}
public string Value
{
get
{
if(_control is ...) return ...
...
}
set
{
if(_control is ...) ((Xxx)_control).Yyy = value;
...
}
}
}
...
Dictionary<string, ControlBoundValueDescription> dictControls =
new Dictionary<string, ControlBoundValueDescription>();
...
// defining mappings (you may also want to populate it automatically,
// by iterating over all the controls you have on your form)
dictControls["UserName"] = new ControlBoundValueDescription(tbUserName);
dictControls["Group"] = new ControlBoundValueDescription(cbxGroup);
...
// working with controls using previously defined mappings
dictControls["UserName"].Value = "guest"; // probably, text box
dictControls["Group"].Value = "Guest Users"; // probably, combo
But the whole idea seems to be bad design. You should probably clarify the problem you're trying to solve.
If I understand your question, you can use Find()
((TextBox)myForm.Controls.Find(Key, true)).Text = Value;
((CheckBox)myForm.Controls.Find(Key, true)).Checked = Boolean.Parse(Value);
