c# - Getting child component values in a custom web control

Question

I have a custom web control having two labels. On the display page I want to modify the text of one of the labels depending on a condition. How to achieve?

Answer 1

答案取决于您如何定义控件。如果标签是公共的，您只需通过控件实例访问标签

if(condition)
    mycontrol.label.Text = "Some text";

如果它是私有的，您将需要控件中的公共方法来更改文本，例如

void SetLabelText(string text)
{
    this.label.Text = text;
}

然后调用方法

if(condition)
    mycontrol.SetLabelText("Some text");
