GridView中动态设置CommandField是否可用或可见的小例子


            复制代码 代码如下: protected void gvMaterial_RowDataBound(object sender, GridViewRowEventArgs e)        {            if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header)            {                e.Row.Cells[0].Visible = false;            }            if (e.Row.RowType == DataControlRowType.DataRow)            {                e.Row.Cells[1].Text = (gvMaterial.PageIndex * gvMaterial.PageSize + e.Row.RowIndex + 1).ToString();                string price;                try //让编辑功能在特定条件下可以用                {                     price = ((TextBox)e.Row.Cells[4].Controls[0]).Text;//点编辑的时候用                }                catch                {                     price = e.Row.Cells[4].Text;    //出始时用                }                                          if (price == "" || price == " ")                {                    e.Row.Cells[7].Controls[0].Visible = false;                }                else                {                    e.Row.Cells[7].Controls[0].Visible = true;                }            }        }
