推荐答案

我写了一个函数来在formview中找到控件:

i write a function to find a control in formview:

#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

thanks erveryone, if have good idea ,i want to know how you do it.thanks

发件人不过是Formview控件而已，它只是在项目中循环并获取文本框

问候

The sender is nothing but the Formview control it self just loop through the items and get the text box
