[shaz jazz]

i am using c#.net. i have added some controls(textbox and checkbox and labels) on a pannel when a button is cliked in form.now i want to add the event(CheckedChanged) on check box.normally its not difficult but i create the control dynamically so how can i add the event dyanmically? further more there is no fixed no of check boxes to be added so i cant make the event handlers prior to execution..

May God help u solv ur problems as well,thx in advance!!

Firstly you can use the same event handler for all your dynamic checkboxes, you can always determine WHICH one was actually checked (or unchecked) using the sender parameter private void DynamicCheckboxes_CheckedChanged(object sender, EventArgs e) { CheckBox checkBox = (CheckBox)sender; Debug.Write("CheckBox: " + checkBox.Name + " checked:" + checkBox.Checked.ToString()); } Now when you dynamically create a checkbox in code you add an event handler thusly: CheckBox myCheckBox = new CheckBox(); myCheckBox.CheckedChanged += new EventHandler(DynamicCheckboxes_CheckedChanged_;

Hi, you need to set an event handler to your control (most likely after having created it). Check the += operator applied to events. yourcontrol.CheckedChanged += twice and VS will complete the line and create a stub for your event handler>; Have a look at InitializeComponent() in your form. Regards.

In addition to what the previous posters said, you can always iterate through the controls-collection, find all the controls that are of type checkbox, and add an event-handler for them. Just give them a name so that you can find them again, if you need to.
