Question

我想隐藏vaadin-grid上的两个滚动条（x和y），但我找不到可行的解决方案。我试着设置

overflow = hidden

vaadin-grid，vaadin-grid-outer-scroller，vaadin-grid-scroller，#table，#scroller等等，但似乎没有任何效果。

我想要启用滚动但我不希望显示丑陋的滚动条。我该如何避免它们？

vaadin-grid版本：5.0.0-beta1
我使用聚合物2.5

我想使用css来处理使用自定义主题的样式：

<dom-module id="my-custom-grid" theme-for="vaadin-grid">
<template>
    <style>
        :host([theme~="my-custom-grid"]) {
            --color-grey-row-selected: #f7f6f6;
            --color-grey-row-salesrank: #e6e6e6;
            width: 600px;
            border: none;
            margin: 0 auto;
        }

        :host([theme~="my-custom-grid"]) [part~="cell"]:not([part~="details-cell"]) {
            border-top: none;
        }

        :host([theme~="my-custom-grid"]) [part~="cell"] ::slotted(vaadin-grid-cell-content) {
            padding: 0;
        }

        :host([theme~="my-custom-grid"]) [part~="header-cell"]:nth-child(1n) {
            min-height: 0;
            min-width: 398px;
            max-width: 398px;
            height: 52px;
            padding: 19px 11px 17px;

            border-bottom: none black;
            font-size: 14px;
            font-family: roboto, sans-serif;
            font-style: normal;
            font-weight: 400;
        }

        :host([theme~="my-custom-grid"]) [part~="header-cell"]:nth-child(2n) {
            min-width: 104px;
            max-width: 104px;

        }

            min-width: 98px;
            max-width: 98px;
        }

        :host([theme~="my-custom-grid"]) [part~="row"] {

Answer 1

vaadin-grid有两个带滚动条的容器元素，所以我们必须隐藏两个滚动条。

尝试下一步：

#table {
    right: -15px;   //we can't set overflow:hidden here as we'll can't to scroll
}

#outerscroller {
    right: -15px;   // and here too
}

#scroller {
    left: -15px;
    overflow: hidden;
}

vaadin-grid {
    overflow: hidden;
}

这仅适用于垂直滚动条，因此您需要执行相同的操作来隐藏horizontall滚动。祝你好运！

解决方案：

:host([theme~="my-custom-grid"]) {
    display: block;
    height: auto;
}

:host([theme~="my-custom-grid"]) #fixedsizer,
:host([theme~="my-custom-grid"]) #outerscroller {
    display: none;
}

:host([theme~="my-custom-grid"]) #table {
    overflow: hidden;
}

Answer 3

我通过在就绪事件上通过编程来做到这一点：

var grid = this.shadowRoot.querySelector('#reportGrid');// your id

grid.$.table.style.overflowX="hidden";

希望它会有所帮助，因为尝试使用模板样式变得疯狂起来。
