Gridview使用记录

1.TemplateField中的绑定

<asp:TemplateField>
                        <ItemTemplate><%# Eval("OCompany.Name") %></ItemTemplate>
                    </asp:TemplateField>

2.通过CheckBox得到选择行的主健值（GridView支持多主健)

        private string GetSelectId()
        {
            //EnsureChildControls();
            GridView gvlist1 = (GridView)this.Controls[0].FindControl("gvlist");

            int icount = gvlist1.Rows.Count;

            string id = string.Empty;

            for (int i = 0; i < gvlist1.Rows.Count; i++)
            {
                CheckBox cb = (CheckBox)gvlist1.Rows[i].FindControl("cb_id");

                 //得到选中行的信息
                if (cb.Checked == true)
                {
                    DataKey dkr = gvlist1.DataKeys[i];

                    id = dkr.Value.ToString();
                }
            }

            return id;
        }

3.动态创建TemplateField

private void TemplateColumn(GridView gvlist, string column, GridListAttribute att)
        {
            TemplateField tf = new TemplateField();

            tf.HeaderText = att.HeaderText;
            tf.HeaderStyle.Width = Unit.Parse(att.Width);

            ColumnTemplate temp = new ColumnTemplate();

            temp.Column = att.Column;

            tf.ItemTemplate = temp;

            gvlist.Columns.Add(tf);
     
            
        }
