How to bind a column collection from view model in .NET MAUI DataGrid?

The .NET MAUI DataGrid provides the support to bind the SfDataGrid.Columns to a property in the ViewModel by having the binding property to be of type ColumnCollection or List<DataGridColumn> in the ViewModel.

Refer the below code example in which the DataGridColumns property is bind to the SfDataGrid.Columns property.

XAML

In the XAML page, bind the DataGridColumns property to the SfDataGrid.Columns.

<syncfusion:SfDataGrid  x:Name="datagrid"
                        ItemsSource="{Binding Employees}"
                        Columns="{Binding DataGridColumns}"
                        AutoGenerateColumnsMode="None"
                        DefaultColumnWidth="155">
</syncfusion:SfDataGrid>

ViewModel.cs

Create a property in the ViewModel class to bind with a type that can be either List<DataGridColumn> or Syncfusion.Maui.DataGrid.ColumnCollection. Assign the appropriate values to this property within the constructor.

private ColumnCollection dataGridColumns;

public ColumnCollection DataGridColumns
{
    get { return dataGridColumns; }
    set
    {
        dataGridColumns = value;
    }
}
public EmployeeViewModel()
{
    this.DataGridColumns = new ColumnCollection
    {
        new DataGridNumericColumn(){ MappingName = "EmployeeID" , HeaderText="Employee ID"},
        new DataGridTextColumn(){ MappingName = "Name" , HeaderText = "Name"},
        new DataGridTextColumn(){ MappingName = "IDNumber", HeaderText ="ID Number"},
    };

}
