hi all, i have 16 checkboxes in a form. (4 in a row and total 4 rows = 4x4) if any one checkbox is checked in a row, i want to disable others. how can i do this ?

Use DataBindings property. Best regards, Alexey.

Hi! Nothing magic about it: Just set the Enabled property of the CheckBoxes you want disabled to false. Regards, mav -- Black holes are the places where god divided by 0...

how do i use databindings for checkbox1, checkbox2, checkbox3, checkbox4 ? (if one is checked, then others must be disabled.) would you please write a simple code for this ?

[alexey N]

Add this line to FormLoad event: checkbox2.DataBindings.Add(new Binding("Enabled", checkbox1, "Checked")); When checkBox1 is checked checkbox2 will be enabled, and when checkBox1 is unchecked checkbox2 will be disabled. Best regards, Alexey.

i think this could be worked CheckBox[] ch1 = new CheckBox[] { checkBox1, checkBox2, checkBox3, checkBox4 }; { for (int x = 0; x < 4; x++) if (ch1[x].Checked) { foreach (CheckBox ch in ch1) { if (ch.CheckState == CheckState.Unchecked) ch.Enabled = false; } } }

Nothing hard to do the above things.... just put all the check boxes in a group box.. it will take care of enabling/disabling the states

The best way of doing this is to use radio buttons instead of checkboxes. That is what radio buttons are for. Roy.

Sorry Roy is right... put radio buttons inside Group Box
