氚云丨开发课— 07 列表的常见使用方法

列表的常见使用方法

1.获取列表勾选的行

protected override voha on[oad(3.SmartForm.LoadListviewResponse

2.字段颜色的修改

response)

base.OnLoad(response);

string , isFormControl = this.Request["isFormControl"]== null ?"": this.Request["isFormcontrol"].ToString();

//设置只在 load 列表数据时加载颜色

if(isFormControl!="1" && isFormControl !="true")

foreach(Dictionary < string, object > data in response.ReturnData)

//设置列名为 Mobile 的颜色为 Red

data["Mobile"】= new

H3.SmartForm.ListViewCustomcell(data["Mobile"】== null ？"--"： data["Mobile"].ToString

3.自定义筛选条件

protected override void OnInit(H3.SmartForm.LoadListviewResponseresponse）

H3.Data.Filter.Filter filter = new H3.Data.Filter.Filter()；//构建过滤器

H3.Data.Filter.And andMatcher  new H3.Data.Filter.And();

andMatcher.Add(new H3.Data.Filter.ItemMatcher("控件编码", H3.Data.ComparisonOperatorType.Equal,"Value"))；//添加查询条件

filter.Matcher = andMatcher;

this.Request.Filter " filter;

base.OnInit(response);

//构造 And 匹配器
4.修改列名
//修改列名称（本方法放在列表设计后端列表类内）
protected override void OnInit(H3.SmartForm.LoadListviewResponseresponse)
Dictionary < string, H3.SmartForm.ListviewColumn > columns-new Dictionary<string, H3.SmartForm.ListviewColumn>();
foreach(string key in response.Columns.Keys)if(key == *eoooooo1")//判断当前列的编码是否是F0000001
//将F0000001列的列名称改成供应商信息
H3.SmartForm.ListviewColumn newCol - new H3.SmartForm.ListViewColumn(
"F0000001",//列编码（对应控件编码）
"供应商信息”//列必称

response.Columns[key].Visible,
response.Columns[key].Sortable,
response.Columns[key].Url，
response.Columns[key].Align,
response.Columns[key].IsLabel,
response.Columns[key]. ShowMode
columns.Add("F0000001", newCol);
else
columns.Add(key, response.Columns[key]);
response.Columns = columns;
5.修改排序列
protected override void OnInit(H3.SmartForm.LoadListViewResponse response)base.OnInft (response)；
response.SortBy =“F0000003"://设置列表默认根据F0000003控件进行排序
//response.SortDirection = H3.Data.Filter.SortDirection.Ascending;//正序排序
response.SortDirection  H3.Data.Filter.SortDirection.Descending;//倒序排序
