----类型转换问题－－－－

[huzhaoliang]

当我用下面的转换时。系统提示无法进行转换，查看了一下，在windows里要包括命名空间"Windows.Form",但我建的是web项目，应该如何操作啊？？？请指教！！
private void DataGrid1_UpdateCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{string Name;
TextBox tb;
//**tb =(TextBox)e.Item.Cells[0].Controls[0];**//无法进行转换！
Name=tb.Text;
DataTable db= this.dataSet11.Tables["Stu"];
DataRow dr = db.NewRow();
dr["Name"]=Name;
db.Rows.Add(dr);
this.sqlDataAdapter1.Update(this.dataSet11);
this.DataGrid1.EditItemIndex=-1;
this.DataGrid1.DataBind();

}

this TextBox is System.Web.UI.WebControls.TextBox, not System.Windows.Forms.TextBox

remove
using System.Windows.Forms;

and use
using System.Web.UI.WebControls;

or do

System.Web.UI.WebControls.TextBox tb;
tb =(System.Web.UI.WebControls.TextBox)e.Item.Cells[0].Controls[0];

[suguanqun]

TextBox tb;
tb =(TextBox)e.Item.Cells[0].Controls[0];

不行啊，我已经包括using System.Web.UI.WebControls;
也不行，还是不能进行类型转换，怎样做呢？

[saucer]

then that means one thing, e.Item.Cells[0].Controls[0] is not a TextBox, try

Response.Write(e.Item.Cells[0].Controls[0].GetType().Name);

[haoliqi]

huzhaoliang () 你的Cells[0]是编辑(或Cells[0]只读)按钮吧,如果是可要给分呀!
