Hi Sessame,

 
Thank you for using Syncfusion Controls.

 
You can achieve your requirement by SfDataGrid.CellCheckBoxClick and SfDataGrid.CurrentCellActivating events like below, 
this.sfDataGrid1.CellCheckBoxClick += sfDataGrid1_CellCheckBoxClick; 
this.sfDataGrid1.CurrentCellActivating += sfDataGrid1_CurrentCellActivating; 
private void sfDataGrid1_CurrentCellActivating(object sender, CurrentCellActivatingEventArgs e) 
{ 
    if (e.DataColumn.GridColumn.MappingName == "IsClosed1") 
        e.Cancel = true; 
} 
 
private void sfDataGrid1_CellCheckBoxClick(object sender, CellCheckBoxClickEventArgs e) 
{ 
    if (e.Column.MappingName == "IsClosed1") 
        e.Cancel = true; 
 
    if (e.Column.MappingName == "IsClosed" && e.Record != null ) 
    { 
        (e.Record as OrderInfo).IsClosed1 = e.NewValue == CheckState.Checked; 
    } 
} 

We have prepared the sample for the same,

 
 
Please refer the below KB for more information’s,

Hi sessame,

 
Thank you for your patience.

 
You can achieve your requirement by setting the HeaderState of the CheckBoxColumn like below, 
FirstLevelNestedGrid.CellCheckBoxClick += FirstLevelNestedGrid_CellCheckBoxClick; 
FirstLevelNestedGrid.CurrentCellActivating += FirstLevelNestedGrid_CurrentCellActivating; 

private void FirstLevelNestedGrid_CurrentCellActivating(object sender, Syncfusion.WinForms.DataGrid.Events.CurrentCellActivatingEventArgs e) 
{ 
    if (e.DataColumn.GridColumn.MappingName == "IsClosed1") 
        e.Cancel = true; 
} 
 
private void FirstLevelNestedGrid_CellCheckBoxClick(object sender, Syncfusion.WinForms.DataGrid.Events.CellCheckBoxClickEventArgs e) 
{ 
    var records = ((e.OriginalSender as DetailsViewDataGrid).DataSource) as List<OrderDetails>; 
    var grid = e.OriginalSender as DetailsViewDataGrid; 
    if (e.Record == null && e.Column.MappingName == "IsClosed") 
    { 
        if (e.NewValue.ToString() == "Checked") 
        { 
            (grid.Columns["IsClosed1"] as GridCheckBoxColumn).GetType().GetProperty("HeaderState", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(grid.Columns["IsClosed1"] as GridCheckBoxColumn, CheckState.Checked); 
        } 
        else 
        { 
            (grid.Columns["IsClosed1"] as GridCheckBoxColumn).GetType().GetProperty("HeaderState", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(grid.Columns["IsClosed1"] as GridCheckBoxColumn, CheckState.Unchecked); 
        } 
 
        for (int i = 0; i < records.Count; i++) 
        { 
            if (e.NewValue.ToString() == "Checked") 
            { 
                (records[i] as OrderDetails).IsClosed1 = true; 
            } 
            else 
            { 
                (records[i] as OrderDetails).IsClosed1 = false; 
            } 
        } 
    } 
    if (e.Column.MappingName == "IsClosed1") 
        e.Cancel = true; 
 
    if (e.Column.MappingName == "IsClosed" && e.Record != null) 
    { 
        (e.Record as OrderDetails).IsClosed1 = e.NewValue == CheckState.Checked; 
    }
