GridView 隐藏某中得些列.并在HeadText上显示相关的信息

private void ShowInformation()




...{


DataTable dt = oss.GetOutStoreSearchResult(oss);


bb = this.gvOutStore.ControlStyle.Height;


if (dt.Rows.Count == 0)




...{


AddDummyData(dt); //如果没有数据时,添加一列空值


for (int i = 1; i < gvOutStore.Columns.Count; i++)




...{


this.gvOutStore.Columns[i].Visible = false; //这个是把除第一列以外得所有列都隐藏起来


}


this.gvOutStore.Columns[0].HeaderText = "显示标题。<table style="vertical-align: bottom; width: 100%; text-align: left"><tr><td align="left" >暂无XXXX信息。</td></tr>";


this.gvOutStore.ControlStyle.Height = 0;


this.hfOutStoreID.Value = "-1";


}


else




...{


for (int i = 1; i < gvOutStore.Columns.Count; i++)




...{


this.gvOutStore.Columns[i].Visible = true; //显示所以已经隐藏起来得列.


}


//this.gvOutStore.ControlStyle.Height = bb;


this.gvOutStore.Columns[0].HeaderText = "";


}


this.gvOutStore.DataSource = dt;


this.gvOutStore.DataBind();


}


//如果为空得时候就添加一行空得记录


private void AddDummyData(DataTable dt)




...{


DataRow newRow = dt.NewRow();


dt.Rows.Add(newRow);


}

我想还有好多其它方法可以做到这一点.

这种法子还有一个缺点是,它得高度不知道怎么弄，我测试了一下，目前还没有发现在什么问题。
