I have 2 check boxes, I want to know how to manage these: if one is checked do that, if the other one is checked do that, if both are checked do both actions.
Also if none are checked and I click on the button to perform the action it should display "Please check one of the options or both."
Thank you for your time

if (!checkBox1.Checked && !checkBox2.Checked)
{
MessageBox.Show("Please select at least one!");
}
else if (checkBox1.Checked && !checkBox2.Checked)
{
MessageBox.Show("You selected the first one!");
}
else if (!checkBox1.Checked && checkBox2.Checked)
{
MessageBox.Show("You selected the second one!");
}
else //Both are checked
{
MessageBox.Show("You selected both!");
}
Also;
if(checkBox1.Checked || checkBox2.Checked)
{
if(checkBox1.Checked) doCheckBox1Stuff();
if(checkBox2.Checked) doCheckBox2Stuff();
}else {
MessageBox.Show("Please select at least one option.");
}
I think you'd want something like this:
private void button1_Click(object sender, EventArgs e) {
if (checkBox1.Checked) {
Console.WriteLine("Do checkBox1 thing.");
}
if (checkBox2.Checked) {
Console.WriteLine("Do checkBox2 thing.");
}
if (!checkBox1.Checked && !checkBox2.Checked) {
Console.WriteLine("Do something since neither checkBox1 and checkBox2 are checked.");
}
}
In the event handler for the button, just verify which buttons are actually checked, ie:
if ( myCheckBox1.Checked && myCheckBox2.Checked )
{
// Do action for both checked.
}
Instead of performing the check-box functionality on button click you could use the OnCheckedChanged event of the check-box and set AutoPostBack to true, in ASP.NET. Then you will can execute the check-box actions automatically and perform the data validation on the button click event.
(WinForms)
private void checkbox1_CheckedChanged(object sender, EventArgs e)
{
//Execute method
}
(ASP.NET)
<asp:CheckBox ID="checkbox" runat="server" OnCheckedChanged="checkbox_OnCheckedChanged" AutoPostBack="true" />
private void checkbox_OnCheckedChanged(object sender, EventArgs e)
{
//Execute method
}
Button Click Event
protected void button_onclick(object sender, EventArgs e)
{
if (!checkbox1.Checked || !checkbox2.Checked)
MessageBox.Show("Error");
}
