问题描述

Hello,
please help me.
Which lines of code are needed to take over the most important EventHandlers?
Example: ValueChanged, SizeChanged, etc...
The element is not displayed correctly.

Thanks for your help.

推荐答案

对不起......我看不到任何指向你尝试过的东西的东西......

我建议，你真的尝试过一些东西（例如抓住一些事件），如果你坚持一个特定的点，你可以问你的问题到底是什么。

I'm sorry ... I couldn't see anything which points me to "what you have tried" ...
I suggest, you really try something (for example catch some Events) and if you stuck at a specific point you could ask your question to exactly this point.

Hallo Ralf，



hier die Eigenschaften die nicht funktionieren：



AutoSize：

in en Enwicklungsumgebung aufFalse gesetzt。



BackColor：

in enwicklungsumgebung aufControlDarkDarkgesetzt。

DieseEuigenschaftfünktionie rt aber auch ohne der ToolStipBar nicht！



尺寸：

In der Enwicklungsumgebung auf250; 18gesetzt。

Es wird nur eine kleine HSrollBar aber miteinemgroßenRahmendrum angezeigt。



ValueChanged：
