XamDataGrid调整星号列

Question

如何调整*列在XamDataGrid中的大小？在本例中，我无法调整department列的大小。

MWE：MainWindow.xaml

<Window x:Class="GridPerformAutoSize.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:igWPF="http://schemas.infragistics.com/xaml/wpf"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        Title="MainWindow"
        Width="800"
        Height="450"
        mc:Ignorable="d">
    <Grid>

        <igWPF:XamDataGrid x:Name="dataGrid">
            <igWPF:XamDataGrid.FieldLayoutSettings>
                <igWPF:FieldLayoutSettings AutoGenerateFields="False" />
            </igWPF:XamDataGrid.FieldLayoutSettings>
            <igWPF:XamDataGrid.FieldLayouts>
                <igWPF:FieldLayout>
                    <igWPF:Field Name="name" />
                    <igWPF:Field Name="department" Width="*" AllowResize="True" />
                    <igWPF:Field Name="salary" />
                    <igWPF:Field Name="email" />
                </igWPF:FieldLayout>
            </igWPF:XamDataGrid.FieldLayouts>
        </igWPF:XamDataGrid>

    </Grid>
</Window>

MainWindow.xaml.cs

using System.Linq;

namespace GridPerformAutoSize
{
    public class Person
    {
        public string name { get; set; }
        public string department { get; set; }
        public string salary { get; set; }
        public string email { get; set; }
    }
    
    public partial class MainWindow
    {
        public MainWindow()
        {
            this.InitializeComponent();

            this.dataGrid.DataSource = Enumerable.Repeat(new Person() { department = "HR", email = "john@hotmail.com", name = "John Smith", salary = "52500" }, 5);
        }
    }
}

我需要做什么才能调整*列的大小？

如何让一列使用所有可用空间，但仍然允许调整大小？

Answer 1

将department字段设置为Width="*"可防止其调整大小。若要启用此字段的大小调整，只需删除该列中的宽度设置即可。

<igWPF:XamDataGrid x:Name="dataGrid" AutoFit="True">
    <igWPF:XamDataGrid.FieldLayoutSettings>
        <igWPF:FieldLayoutSettings AutoGenerateFields="False" AutoFitMode="Always" />
    </igWPF:XamDataGrid.FieldLayoutSettings>
    <igWPF:XamDataGrid.FieldLayouts>
        <igWPF:FieldLayout>
            <igWPF:Field Name="name" />
            <igWPF:Field Name="department" />
            <igWPF:Field Name="salary" />
            <igWPF:Field Name="email" />
        </igWPF:FieldLayout>
    </igWPF:XamDataGrid.FieldLayouts>
</igWPF:XamDataGrid>

您还可以尝试将单元格和标签的大小设置为AutoFit="True"，而不需要滚动。

问题__：如何让一列使用所有可用空间，但仍然允许调整大小？

应答__：您可以为所有列设置Width="Auto"，但希望使用所有可用空间但仍然允许调整大小的列除外。对于本列，不要设置Width属性。
