DataGridView问题

Question

DataGridView中如何获得当前单元格中选中的文本？

Answer 1

 DataGridView.CurrentRow.Cells["字段名"].Value;或CurrentCells

Answer 2

当前单元格处于编辑状态，
然后从它的值中选中一部分,
比如当前单元格的值是"abcdefg",
然后进入编辑状态后，
从里面选中"efg"，
怎么获得选中的值?

Answer 3

他有个row的方法.里面有个e属性.你可以自己找一下.好象是e.row[0][0].text吧.记不清了.大概是这个意思~

Answer 4

for( i=1;i<document.all.GridView.rows.length;i++)
{
 alert(document.all.GridView.rows(i).cells(0).innerText);
}
看看行吗？js获取

Answer 5

以上获取的第一个格内的内容(cells(0))

Answer 6

这个问题貌似就很复杂了哦,因为DataGridViewTextBoxCell是没有selection changed事件的哟,而且也没有selection的属性的,所以你得重写datagrid控件= =#,貌似工作量有点大

Answer 7

但是有个简洁的方式那就是你用模板自定义datagridview列然后承载标准的textbox控件然后访问标准textbox控件可以得到里面值
用this.textBox1.SelectedText可以获取选取属性using System;

Answer 8

选中efg后直接Ctrl+C不就行了，或者 右键－复制
如果没有在编辑状态下Ctrl+C的内容随着SelectMode不同而变化，有的是整个单元格的有的整行的。

Answer 9

哭啊，我知道Ctrl+C,Ctrl+V也可以用，但我想用编程的方式实现啊
那怎么模拟Ctrl+C,Ctrl+V的事件？---------------------------------
首先要谢谢atlasroben，但我已经重写了三个模板了，快疯了，可不可以不重写啊……
