如何将按键事件添加到Property Grid Veiw [英] How Can I Add Key Press Event To Property Grid Veiw

问题描述

我正在使用visual studio 2008 .Net 3.5 WindowsApllication开发我的应用程序，我正在使用属性网格视图。

我想在用户在datafeild上写一些内容时限制字符串的长度，例如maxlength 100 user绝不允许写更多100

所以我想在属性网格中调用KeyPress事件我没有找到

如果用户在写东西时怎么办？ Propertgrid datafeild，我使用了ProperyvalueChanged事件，但它没有用？

i am developing my application with visual studio 2008 .Net 3.5 WindowsApllication where i am using property grid veiw.
I want to limit length of string when user write something on datafeild for example maxlength 100 user must not allowed to write more that 100
So i want to call KeyPress event in property grid which i didn#t find
How can i do so when user write something in Propertgrid datafeild, I used ProperyvalueChanged Event but it didnt work ??????????

推荐答案

使用CellValidating检查长度是否超过100。 ..如果设置e.Cancel = false所以它不会传播。



如果一切正常，请使用CellValidated事件来保存值



如果这有帮助，请花些时间接受解决方案，以便其他人可以找到它。

Use CellValidating to check if the length is longer then 100...if it is set e.Cancel = false so it doesn't propagate.

If everything is OK, use CellValidated event to save the value

If this helps, please take time to accept the solution so others may find it.

使用

validation property

或者你可以使用

jquery validation

来验证te这类工作..
