我需要使用RadWizard更改NextButton的文本

Question

我试图从后面的代码更改radwizard中的下一个按钮的文本，有人可以帮助我吗？

我有四个步骤，我希望能够在向导的特定步骤中更改下一个按钮的文本，这是否可能

C＃

    protected void rwzPurchase_NextButtonClick1(object sender, WizardEventArgs e)
    {
        if (rwzPurchase.ActiveStep.Title == "Grower Information")
        {
            //Here is where I want to change the text of button if we are in this specific step
            RadButton button = (RadButton)sender;
            button.Text = "test";
            this.rwzPurchase.CommandArea.CommandElements.Add(button);
        }
    }
