使用虚拟滚动kendo-ui网格时,没有可见的滚动。
我正在使用虚拟滚动方式来显示数据库中的某些记录,但是我在网格中看不到任何滚动,并且它仅显示前六行。
我不明白我的问题在哪里。
$("#cargoGrid").kendoGrid({
dataSource: {
serverPaging: true,
serverSorting: true,
pageSize: 20,
transport: {
read: {
url: "/frmPermission/api/readAllCargo",
type: "POST",
contentType: "application/json",
dataType: "json",
},
parameterMap: function (options) {
return JSON.stringify(options);
}
},
schema: {
data: "data",
total: "total",
model: {
fields: {
cargoId: {
type: "number"
},
title: {
type: "string"
},
}
}
},
},
scrollable: {
virtual: true
},
pageable: {
numeric: false,
previousNext: false,
messages: {
display: "تعداد {2} رکورد نمایش داده شده است",
empty: "اطلاعاتی برای نمایش وجود ندارد"
}
},
columns: [
{field: "cargoId", title: "Id", hidden: true},
{field: "title", title: "نوع بار"},
{
filed: "",
title: "انتخاب",
template: "<button class='select k-button' onclick=\"clickSelectCargo( #=cargoId# , '#=title#' )\">انتخاب</button>",
width: "200px"
}
],
selectable: "single",
// sortable: true
});
我发现我使用“ sortable:true”时,我单击了它的标题栏,但单击前没有显示虚拟滚动
