Dialog Boxes in Windows Forms Applications

First create a project for a Windows Forms application in Visual Studio.

Then open the Form1.cs GUI file and make the design with one MenuStrip, two TextBoxes and a Label and drag an openfileDialog, saveFileDialog, folderBrowserDialog, colorDialog and fontDialogs). Make one Menu as in the following:



Now we move to the code.

openFileDialog Click Event

private void openDialogToolStripMenuItem_Click(object sender, EventArgs e)
{
    openFileDialog1.Filter = "Text file (*.txt)|*.txt|All file(*.*)|*.*";
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        stropen = openFileDialog1.FileName;
        textBox1.Text = System.IO.File.ReadAllText(stropen);
    }
}

saveFileDialog Click Event

Write text in the TextBox area and then click on the Save menu option.

private void saveDialogToolStripMenuItem_Click(object sender, EventArgs e)
{
    saveFileDialog1.Filter = "Text file (*.txt)|*.txt|All file(*.*)|*.*";
    if (saveFileDialog1.ShowDialog() == DialogResult.OK)
    {
        strsave = saveFileDialog1.FileName;
        System.IO.File.WriteAllText(strsave, textBox1.Text);
    }
}

fontDialog Click Event

private void fontDialogToolStripMenuItem_Click(object sender, EventArgs e)
{
    if (fontDialog1.ShowDialog() == DialogResult.OK)
    {
        textBox1.Font = fontDialog1.Font;
        textBox1.ForeColor = fontDialog1.Color;

    }
}

colorDialog Click Event

private void colorDialogToolStripMenuItem_Click(object sender, EventArgs e)
{
    if (colorDialog1.ShowDialog() == DialogResult.OK)
    {
        //this.BackColor = colorDialog1.Color;
        //menuStrip1.BackColor = colorDialog1.Color;
        textBox1.BackColor = colorDialog1.Color;
    }
}

browserDialog Click Event

private void browseDialogToolStripMenuItem_Click(object sender, EventArgs e)
{
    folderBrowserDialog1.RootFolder = Environment.SpecialFolder.Desktop;
    if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
    {
        textBox2.Text = folderBrowserDialog1.SelectedPath;
    }
}

Thank you.
