copied!<p>I think by understanding this example you can do what you're attending to do :</p> <p>I have a main form called <code>Form1</code> I want to show User Choices in this form . and also I added a new form called <code>Preferences</code> so user will be able to choose date Format and Keyboard Layout : </p> <p>my radio buttons are named like this :</p> <pre><code>RB_D_1 RB_D_2 . . . </code></pre> <p>after user clicks on <code>Submit Changes</code> we'll check which radioButton is selected and store it's <code>Text</code> property (ex <code>RB_D_1.text</code> is "dd/MM/yyyy" ) to a <code>Public String Variable</code> called <code>DateFormat</code> here we go :</p> <pre><code> public string DataFormat, KeyboardFormat; private void CMDSubmit_Click(object sender, EventArgs e) { if (RB_D_1.Checked) DataFormat = RB_D_1.Text; else if (RB_D_2.Checked) DataFormat = RB_D_2.Text; else if (RB_D_3.Checked) DataFormat = RB_D_3.Text; else if (RB_D_4.Checked) DataFormat = RB_D_4.Text; else DataFormat = "MM/DD/YYYY"; // default format //-------------------------------- if (RB_L_1.Checked) KeyboardFormat = RB_L_1.Text; else if (RB_L_2.Checked) KeyboardFormat = RB_L_2.Text; else if (RB_L_3.Checked) KeyboardFormat = RB_L_3.Text; else if (RB_L_4.Checked) KeyboardFormat = RB_L_4.Text; else KeyboardFormat = "QWERTY"; // default format this.Close(); } </code></pre> <p>now we have saved user choices in two string variables so we can reach them from our <code>Form1</code></p> <p>in <code>Form1</code> whenever user clicks on <code>Setting</code> we'll make an object from our <code>Preferences</code> form and Show it to user after closing the Preferences form , we'll check those two string Variables which we already talked about and decide what to do with those results :</p> <p>for example I stored those results into another two string variables and Showed Them in <code>TextBoxes</code></p> <pre><code> private void CMDSettings_Click(object sender, EventArgs e) { // showing the Preferences form to user Preferences pref = new Preferences(); pref.ShowDialog(); // getting results from Preferences Form dateFormat = pref.DataFormat; keyboardFormat = pref.KeyboardFormat; // Showing the Result in TextBoxes textBox1.Text = dateFormat ; textBox2.Text = keyboardFormat; } </code></pre> <p><strong>UPDATE 2 :</strong></p> <p>change <code>DateStamp()</code> like this :</p> <pre><code>private void DateStamp() { if (dateFormat.ToUpper() == "DD/MM/YYYY") { int CaretPosition = richTextBoxPrintCtrl1.SelectionStart; string TextBefore = richTextBoxPrintCtrl1.Text.Substring(0, CaretPosition); string textAfter = richTextBoxPrintCtrl1.Text.Substring(CaretPosition); string currentDate = DateTime.Now.ToString("dd-MM-yyyy"); richTextBoxPrintCtrl1.SelectedText = currentDate; } else if (dateFormat.ToUpper() == "MM/DD/YYYY") { int CaretPosition = richTextBoxPrintCtrl1.SelectionStart; string TextBefore = richTextBoxPrintCtrl1.Text.Substring(0, CaretPosition); string textAfter = richTextBoxPrintCtrl1.Text.Substring(CaretPosition); string currentDate = DateTime.Now.ToString("MM-dd-yyyy"); richTextBoxPrintCtrl1.SelectedText = currentDate; } else if (dateFormat.ToUpper() == "YYYY/DD/MM") { int CaretPosition = richTextBoxPrintCtrl1.SelectionStart; string TextBefore = richTextBoxPrintCtrl1.Text.Substring(0, CaretPosition); string textAfter = richTextBoxPrintCtrl1.Text.Substring(CaretPosition); string currentDate = DateTime.Now.ToString("yyyy-dd-MM"); richTextBoxPrintCtrl1.SelectedText = currentDate; } else if (dateFormat.ToUpper() == "YYYY/MM/DD") { int CaretPosition = richTextBoxPrintCtrl1.SelectionStart; string TextBefore = richTextBoxPrintCtrl1.Text.Substring(0, CaretPosition); string textAfter = richTextBoxPrintCtrl1.Text.Substring(CaretPosition); string currentDate = DateTime.Now.ToString("yyyy-MM-dd"); richTextBoxPrintCtrl1.SelectedText = currentDate; } } </code></pre> <p><strong>UPDATE 3 :</strong></p> <p>for remembering user choices do this :</p> <p>add this function to <code>Preferences</code></p> <pre><code> public void UpdateUserChoice(string date,string keyboard) { if (date == RB_D_1.Text) RB_D_1.Checked = true; else if (date == RB_D_2.Text) RB_D_2.Checked = true; else if (date == RB_D_3.Text) RB_D_3.Checked = true; else if (date == RB_D_4.Text) RB_D_4.Checked = true; //--------------------------- if (keyboard == RB_L_1.Text) RB_L_1.Checked = true; else if (keyboard == RB_L_2.Text) RB_L_2.Checked = true; else if (keyboard == RB_L_3.Text) RB_L_3.Checked = true; else if (keyboard == RB_L_4.Text) RB_L_4.Checked = true; } </code></pre> <p>and change the old way of showing to user like this : </p> <pre><code> private void CMDSettings_Click(object sender, EventArgs e) { Preferences pref = new Preferences(); pref.UpdateUserChoice(dateFormat, keyboardFormat); pref.ShowDialog(); dateFormat = pref.DataFormat; keyboardFormat = pref.KeyboardFormat; textBox2.Text = keyboardFormat; } </code></pre>
