WPF Datagrid Binding field-CodePudding

I have such a class,

public class Class1
{
    public bool IsSelected { get; set; } = false;
    public List<BaseInfo> baseInfos { get; set; }
}

and a datagrid

<DataGrid
            hc:DataGridAttach.CanUnselectAllWithBlankArea="True"
            AutoGenerateColumns="True"
            AutoGeneratingColumn="DataGrid_AutoGeneratingColumn"
            HeadersVisibility="All"
            IsReadOnly="True"
            ItemsSource="{Binding Class1}"
            RowHeaderWidth="60">
            <DataGrid.RowHeaderTemplate>
                <DataTemplate>
                    <CheckBox IsChecked="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=DataGridRow}}" />
                </DataTemplate>
            </DataGrid.RowHeaderTemplate>
        </DataGrid>

I can't actually do that How should I do to baseInfos Set AutoGenerateColumns="True" Automatically generated Columns, Thank you in advance!

CodePudding user response：

ItemsSource binding should be a list and not a single class, and the IsSelected is expected to be a property inside BaseInfo and not something outside of it!! Could not understand why you have Class1 as it does not help in anything!!

so add public bool IsSelected { get; set; } = false; to the class BaseInfo. something like that:

public class BaseInfo {
     public bool IsSelected { get; set; } = false;
     public string Name { get; set; }
     public string SOMETHING { get; set; }
}

Autogeneratecolumns property will automatically create empty columns for you，

but if you want create new row ,You need to create a list of Class1 and bind it to itemsource

.cs:

    public List<Class1> ClassList
    {
        get
        {
            return classList?? (classList= new List<Class1>());
        }
        set
        {
            classList= value;
        }
    }
    List<Class1> classList;

add some items:

ClassList.Add(new Class1
                {
                    IsSelected = true,
                });
                ClassList.Add(new Class1
                {
                    IsSelected = true,
                });

xaml:

<DataGrid ItemsSource="{Binding ClassList}">
</DataGrid>
