如何在Xamarin.Forms中的网格中启用边框 [英] How to enable borders in Grid in Xamarin.Forms

问题描述

我正在Xamarin.Forms中构建一个网格. 我想添加表格等边框. 我以为可以在定义行和列时添加边框，但是失败了. 谁能帮我? 这是我当前的代码.

I'm building a grid in Xamarin.Forms. And I'd like to add borders like tables. I thought that I could add the border when defining rows and columns, but failed. Can anyone help me? This is my current code.

Grid grid = new Grid {
    VerticalOptions = LayoutOptions.FillAndExpand,
    RowDefinitions = {
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },
        new RowDefinition { Height = GridLength.Auto },

    },
    ColumnDefinitions = {
        new ColumnDefinition { Width = new GridLength (1, GridUnitType.Star) },
        new ColumnDefinition { Width = new GridLength (5, GridUnitType.Star) },
        new ColumnDefinition { Width = new GridLength (1, GridUnitType.Star) },
    }
};

推荐答案

GridView没有Border属性，但是:

只需将grid.BackgroundColor设置为所需的边框颜色值，然后将grid.ColumnSpacing和grid.RowSpacing设置为某个值，并确保添加到网格的所有控件都正确设置了自己的BackgroundColor.

Just set grid.BackgroundColor to your desired border color value, then set grid.ColumnSpacing and grid.RowSpacing to some value and make sure all controls you add to the grid have own BackgroundColor set correctly.
