Hi Subhadip,

Read my Answers below.

Q1 VALIDATION FOR RADIO BUTTON IN NOT CHECKED ?


if (!radioButton1.Checked)

 { 

      MessageBox.Show("Please select one option!")

 }

Q2 VALIDATION FOR RADIO BUTTON IN NOT CHECKED ?


if (!checkBox1.Checked)

 { 

      MessageBox.Show("Please select one option!")

 }

Q3 VALIDATION FOR DROP DOWN BOX IF NOT SELECTED
You can make the index of the default option is 0 and write the below code.


if(comboBox1.SelectedIndex == 0)

{

      MessageBox.Show("Please select one option!")

}

Q4 VALIDATION FOR PHONE NO (should not exit 10 for mobile and 8 for land phone & must be integer)


 String val = textBox1.Text.ToString();

 Regex reg = new Regex(@"(^\d{8}$)|(^\d{10}$)", RegexOptions.None);

if(!reg.IsMatch(val))

{

    MessageBox.Show("Please enter a valid phone / Mobile number");

}

Hope my answers were helpful.

Rupesh Kumar Tiwari
