关于winform 中 datagrid 的问题
用什么方法可以得到鼠标在表上点击选择的记录,以方便操作该记录。

------解决方案--------------------
private void imageShow_DoubleClick(object sender, System.EventArgs e)
{
int y = imageShow.CurrentCell.ColumnNumber;
int x = imageShow.CurrentCell.RowNumber;
MessageBox.Show(imageShow[x,y].ToString());
}
------解决方案--------------------
//基于WindowsForms
取出DataGrid当前行绑定的DataTable的值。

如果DataRowView drv = (DataRowView)this.BindingContext[this.ds,this.ds.Tables[0].TableName].Current;
获取到drv就可以改数据,
DataRow dw = drv.Row; // 得到DataRow,
string s = dw[ "col1 "].ToString();//想得到某一列的值
DataTable dt = dw.Table;//得到DataTable
DataSet ds = dt.DataSet;
