本人是初学者遇到如下问题:
一个按钮和一个DataGrid,DataGrid的数据源为空,单击按钮可在DataGrid添加一行,并且可以编辑内容,保存删除,应当怎样写

------解决方案--------------------

if (ds.tables[0].rows.count==0)
{
adddummydata(ds)
}


private void adddummyData(dataset ds)
{datatable dt =ds.tables[0];
datarow newrow=dt.newrow();
dt.rows.add(newrow);
}

------解决方案--------------------
<asp:DataGrid id= "DataGrid1 " runat= "server " BorderColor= "Aqua " AutoGenerateColumns= "False " Width= "376px "
Font-Size= "12px ">
<Columns>
<asp:BoundColumn DataField= "id " HeaderText= "ID "> </asp:BoundColumn>
<asp:BoundColumn DataField= "name " HeaderText= "NAME "> </asp:BoundColumn>
<asp:EditCommandColumn ButtonType= "LinkButton " UpdateText= "更新 " CancelText= "取消 " EditText= "编辑 "> </asp:EditCommandColumn>
<asp:ButtonColumn Text= "删除 " CommandName= "Delete "> </asp:ButtonColumn>
</Columns>
</asp:DataGrid>
<asp:Button id= "Button1 " runat= "server " Text= "Add Row "> </asp:Button>
