How to get the expression in my button event instead of apply button?

Hi Jin,

You could apply the chosen filter expressions on your custom button using the following approach:

protected void Button1_Click(object sender, EventArgs e)
{
    RadFilter1.FireApplyCommand();
}

That should do the trick.
