checkbox - asp.net

I have a checkbox named cbSelct. In a botton_click event i wrote

cbSelect.Checked=true

is the above code in the code behind page causes for a cbSelected_CheckedChanged event?

I created a new website and place a checkbox named cbSelect and a button.

protected void cbSelect_CheckedChanged(object sender, EventArgs e)
{
    Response.Write("testMessage ");
}
protected void Button1_Click(object sender, EventArgs e)
{
    cbSelect.Checked = !cbSelect.Checked;
}

I put a break point inside cbSelect_CheckedChanged event. Now according to the answers i got below,开发者_Go百科 i understand that , if i clicked button it should break on cbSelect_CheckedChanged function. But i think cbSelect_CheckedChanged event is not firing while clicking the button.

Its affect CheckedChanged event.Before that you must use/create that event.

EDIT

make the AutoPostBack property of checkbox to true

EDIT

protected void Button1_Click(object sender, EventArgs e)
{
    cbSelect.Checked = !cbSelect.Checked;
cbSelect_CheckedChanged(cbSelect,  e);


}

Yes, it will cause the cbSelected_CheckedChanged event to be fired but only if you have defined a cbSelected_CheckedChanged event.

You can try it -

private void cbSelected_CheckedChanged (Object sender, EventArgs e) 
{
   //your code
}

Place a break point here and debug your code. You will find that the cbSelected_CheckedChanged event will be fired.
