GridView动态添加EmptyDataTemplate的例子
下面代码直接拷贝即可执行。
ASPX 代码

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
ICollection CreateDataSource()
{
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("id", typeof(Int32)));
dt.Columns.Add(new DataColumn("text", typeof(string)));
//DataRow dr;
//for (int i = 0; i < 6; i++) {
// dr = dt.NewRow();
// dr[0] = i;
// dr[1] = "列表项目 " + i.ToString();
// dt.Rows.Add(dr);
//}
DataView dv = new DataView(dt);
return dv;
}
public class EmptyDataTemplate : ITemplate
{
private DataControlRowType templateType;
public EmptyDataTemplate(DataControlRowType type)
{
templateType = type;
}
public void InstantiateIn(System.Web.UI.Control container)
{
switch (templateType)
{
case DataControlRowType.EmptyDataRow:
TextBox lc = new TextBox();
lc.Text = " EmptyDataTemplate 显示的内容";
container.Controls.Add(lc);
break;
default:
break;
}
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
EmptyDataTemplate x = new EmptyDataTemplate(DataControlRowType.EmptyDataRow);
GridView1.EmptyDataTemplate = x;
GridView1.DataSource = CreateDataSource();//注意这里一定要空数据，不能没有数据绑定。
GridView1.DataBind();
}
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//给 EmptyDataTemplate 添加更多的内容
if (e.Row.RowType == DataControlRowType.EmptyDataRow)
{
TableCell c = new TableCell();
c.Controls.Add(new TextBox());
e.Row.Cells.Add(c);
}
}
