项目总结
1.绑定数据到dropDownlist,去掉重复的项。
public void bindModels()
{string yh = Session["userName"].ToString();
DataSet dsinfo = tiezibll.GetList(" creater='" + yh + "'");
string idlist = "";
if (dsinfo.Tables[0].Rows.Count > 0)
{
for (int i = 0; i < dsinfo.Tables[0].Rows.Count; i++)
{
string mid = dsinfo.Tables[0].Rows[i]["mid"].ToString();
idlist += mid + ",";
}
string[] kk = idlist.Substring(0, idlist.LastIndexOf(",")).Split(',');
List<string> liststring = new List<string>();
foreach (string eachstr in kk)
{
if (!liststring.Contains(eachstr))
{
liststring.Add(eachstr);
}
}
string kkk = "";
foreach (object s in liststring)
{
kkk += s + ",";
}
string newstr = kkk.Substring(0, kkk.LastIndexOf(","));
DataSet ds = Modelbll.GetList(" id in (" + newstr + ")");
if (ds.Tables[0].Rows.Count > 0)
{
datalist_models.DataSource = ds.Tables[0];
datalist_models.DataBind();
}
else
{
datalist_models.DataSource = "";
datalist_models.DataBind();
}
}
else
{
datalist_models.DataSource = "";
datalist_models.DataBind();
}
}
public void Binddrop()
{
string yh = Session["userName"].ToString();
DataSet dsinfo = tiezibll.GetList(" creater='" + yh + "'");
string idlist = "";
if (dsinfo.Tables[0].Rows.Count > 0)
{
for (int i = 0; i < dsinfo.Tables[0].Rows.Count; i++)
{
string mid = dsinfo.Tables[0].Rows[i]["mid"].ToString();
idlist += mid + ",";
}
string[] kk = idlist.Substring(0, idlist.LastIndexOf(",")).Split(',');
List<string> liststring = new List<string>();
foreach (string eachstr in kk)
{
if (!liststring.Contains(eachstr))
{
liststring.Add(eachstr);
}
}
string kkk = "";
foreach (object s in liststring)
{
kkk += s + ",";
}
string newstr = kkk.Substring(0, kkk.LastIndexOf(","));
DataSet ds = Modelbll.GetList(" id in (" + newstr + ")");
if (ds.Tables[0].Rows.Count > 0)
{
this.DropDownList1.DataSource = ds;
this.DropDownList1.DataTextField = "Model_name";
this.DropDownList1.DataValueField = "id";
this.DropDownList1.DataBind();
}
else
{
this.DropDownList1.DataSource = ds;
this.DropDownList1.DataTextField = "Model_name";
this.DropDownList1.DataValueField = "id";
this.DropDownList1.DataBind();
}
}
else
{
this.DropDownList1.DataSource = null;
this.DropDownList1.DataTextField = "Model_name";
this.DropDownList1.DataValueField = "id";
this.DropDownList1.DataBind();
}
}
B.数据绑定（反选）
//datalist
//foreach (DataListItem item in DL_Main.Items)
//{
// CheckBox cb = (CheckBox)item.FindControl("selected");
// if (cb.Checked == false)
// cb.Checked = true;
// else
// cb.Checked = false;
//}
//repeater
for (int i = 0; i < this.DL_Main.Items.Count; i++)
{
CheckBox cb = (CheckBox)DL_Main.Items[i].FindControl("selected");
if (cb.Checked == false)
cb.Checked = true;
else
cb.Checked = false;
}
//查询数组里是否包含指定的字符。
string[] fwlist = serverlist.Split('-');
bool k = fwlist.Contains<string>("72");
ItemDataBound事件
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
HyperLink jr = (HyperLink)e.Item.FindControl("jr_qianyue");//链接（查询reapter的服务器控件）
}
<%#Eval("Ischarge").ToString() == "0" || Eval("Ischarge").ToString() == ""? "免费" : "价格：<span style='color:red;'>" + Eval("price").ToString() + "元</span>"%>
<%#Eval("Model_name").ToString().Length >10? Eval("Model_name").ToString().Substring(0, 10) + "....." : Eval("Model_name").ToString()%>
<asp:HyperLink id=Hyperlink3 runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "ID") %>' Visible="False">
System.Web.UI.HtmlControls.HtmlAnchor linkSend = ((System.Web.UI.HtmlControls.HtmlAnchor)e.Item.FindControl("linkSend"));(查找reapter绑定数据之间的html控件
string rptime =DateTime.Parse( ds_hf.Tables[0].Rows[0]["ReplayTime"].ToString()).ToString("yyyy-MM-dd HH:mm:ss");（显示24小时制的时间）
