推荐答案

#region       
        protected Control GetControlOfFormView(FormView fv, string strControlID)
        {
            Control ctl = new Control();
            FormViewRow fvr = fv.Row;
            TableCell tc = new TableCell();
            Control CellCtl = new Control();
            int nCell,nCellCtl;
            int j, k;
            nCell = fvr.Cells.Count;
            for (j = 0; j < nCell; j++)
            {
                tc = fvr.Cells[j];
                nCellCtl = tc.Controls.Count;
                for (k = 0; k < nCellCtl; k++)
                {
                    CellCtl = tc.Controls[k];
                    ctl = CellCtl.FindControl(strControlID);
                    if (ctl != null)
                    {
                        k = nCellCtl;
                        j = nCell;
                    }
                }
            }
            return ctl;
        }
        #endregion

使用它:

use it :

protected void FormView1_DataBound(object sender, EventArgs e)
{
   DataRowView row = (DataRowView)FormView1.DataItem;
   TextBox tb = null;

   tb = (TextBox)GetControlOfFormView(FormView1, "textbox");
   tb.Text = row["Bsf_FormID"].ToString();
}

谢谢erveryone，如果有个好主意，我想知道你怎么做.谢谢
