I have a SelectedIndexChanged event handler for a combo so that if the user changes his selection a child window is spawned.
However I also want to set a default value for the combo box e.g. using this code:
comboX.SelectedIndex=0;
Is there a way to set the default without firing the associated event (or perhaps a better way of doing this)?
Thanks!
Everyone's had this problem at some time.
Some options:
Set the selected index before adding the event handler (not possible if you are adding the event handler in designer generated code).
If the event is a method in the same class that the index is set, add a boolean field called "settingUp" or similar, set it to be true during initialization. In the event handler, only do your custom action when settingUp is false.
some sample code to illustrate what Jim said
1. in designer.cs, you set the initial value
this.comboBox1.SelectedIndex = 0;
2. in form.cs, add event handler after all the components have been initialized
public Form1() {
InitializeComponent();
this.comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_SelectedIndexChanged);
}
void comboBox1_SelectedIndexChanged(object sender, EventArgs e) {
// Create a new form for what is selected
}
