我在Page后面的代码是

protected void Page_Load(object sender, System.EventArgs e)
{
//Button btnInsert = (Button)GridView1.FooterRow.FindControl("btnInsert");
//btnInsert.Attributes.Add("onclick", "return validate()");
if (!IsPostBack)
{
GridFill();
}
}
protected void GridFill()
{
try
{
con.Open();
SqlCommand cmd = new SqlCommand("Select * from emp", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
GridView1.DataSource = ds;
GridView1.DataBind();
}
else
{
ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
GridView1.DataSource = ds;
GridView1.DataBind();
int columncount = GridView1.Rows[0].Cells.Count;
GridView1.Rows[0].Cells.Clear();
GridView1.Rows[0].Cells.Add(new TableCell());
GridView1.Rows[0].Cells[0].ColumnSpan = columncount;
GridView1.Rows[0].Cells[0].Text = "No Records Found";
}
}
catch
{
}
}

查看您的aspx设计代码，并从gridview代码中删除DataSourceID
see your aspx design code, and reomve DataSourceID from gridview code
<asp:gridview id="GridView1" runat="server" allowsorting="True" xmlns:asp="#unknown">
AutoGenerateColumns="False" CellPadding="4" DataKeyNames="taskid"
DataSourceID="SqlDataSource1" ForeColor="#333333"
Width="960px" AutoGenerateSelectButton="True" Font-Bold="False"
Font-Italic="False" >
</asp:gridview>
使用
use
<asp:gridview id="GridView1" runat="server" allowsorting="True" xmlns:asp="#unknown">
AutoGenerateColumns="False" CellPadding="4"
ForeColor="#333333"
Width="960px" AutoGenerateSelectButton="True" Font-Bold="False"
Font-Italic="False" >
</asp:gridview>
