在dev express grid控件中清除所有列和行 [英] Clear all Columns and row in a dev express grid control
问题描述
我的窗口应用程序(VS2005)中有一个datagridview和一个dev express gridcontrol,在我的datagridview中有
我有来自我的数据库(SQL)的所有表。因此,当我双击datagridview中的表时,该特定表中的所有数据都显示为gridcontrol。
我的问题是devexpress gridcontrol不会清除之前的querry,所以不要只显示选中的表,它显示所有以前选择的表。我尝试使用:
I have a datagridview and a dev express gridcontrol in my window application (VS2005) ,
in my datagridview i have all the tables from my Database (SQL) . So when i double click a table in the datagridview all the data in that particular table is shown the gridcontrol.
My problem is that the devexpress gridcontrol does not clear the previous querry , so instead of showing only the selected table , it shows all the previous selected tables. I tried using :
gridControl1.DataSource = null;
gridView1.Columns.Clear();
但它不起作用。
可以有人请帮助我...我对C#很新,所以我不知道如何解决我的问题。
谢谢: - )
but it does not work.
Can somebody please help me...I'm very new to C# so i ve no idea how to solve my problem.
Thanks :-)
推荐答案
试试这个,
try this,
gridControl1.DataSource = null;
gridControl1.DataBind();
我自己尝试一下:)
I try this myself :)
while (gridView1.RowCount!=0)
{
gridView1.SelectAll();
gridView1.DeleteSelectedRows();
}
