GridView通过BoundField添加列出错
DataTable dt = new DataTable();
for (int i = 1; i <= 6; i++) {
BoundField bf = new BoundField();
bf.DataField = "ID" + i;
bf.HeaderText = "ID";
bf.HtmlEncode = true;
DataColumn dc = new DataColumn();
this.GridView1.Columns.Add(bf); }
for (int i = 0; i < 100; i++) {
dt.Rows.Add(i, "He" + i.ToString("00"), "He", "Jian", "Bo", new DateTime(2008, 8, 8)); }
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
前台代码只有
<asp:GridView ID="GridView1" runat="server" Width="100%" Height="55px"> </asp:GridView>
错误：BoundField列没有添加进去，导致 dt.Rows.Add出错。而且单独添加BoundField表格一片空白，显然没有添加进去
------解决方案--------------------
你没有创建列啊
DataTable dt = new DataTable();
for (int i = 1; i <= 6; i++) {
BoundField bf = new BoundField();
bf.DataField = "ID" + i;
bf.HeaderText = "ID";
bf.HtmlEncode = true;
DataColumn dc = new DataColumn();
this.GridView1.Columns.Add(bf); }
for (int i = 0; i < 100; i++) {
dt.Rows.Add(i, "He" + i.ToString("00"), "He", "Jian", "Bo", new DateTime(2008, 8, 8)); }
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
前台代码只有
<asp:GridView ID="GridView1" runat="server" Width="100%" Height="55px"> </asp:GridView>

你没有创建列啊
- C# code
dt.Columns.Add(new System.Data.DataColumn("UserId", typeof(System.Int32)));
dt.Columns.Add(new System.Data.DataColumn("ID1", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("ID2", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("ID3", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("ID4", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("ID5", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("ID6", typeof(System.String)));
------解决方案--------------------
