问题描述
我想在列的标题中添加一个文本框，并且当其上的按键事件被触发时，我需要使用表单中的函数(而非Java).它必须将textbox.text值传递给该函数.我需要它在gridview中进行搜索.
我将要在过滤器中添加它，如果我可以将事件视为StoreReadDataEventArgs.我 BOLDED vb.net中需要捕获参数的代码.
我怎样才能做到这一点 ?谢谢.
我的代码
Hi,
I want to add a textbox in the header of a column and when keypress event on it is fired i need to use a function (not java) from my form. It must pass the textbox.text value to that fuction.I need it to make a search in the gridview.
I will want to add it in the filter and if i can take the event as StoreReadDataEventArgs . I BOLDED the code in vb.net where i need to catch the parameter.
