How to condtionaly remove buttons from a cell

[Greg]

WIthin a SfDataGrid, when a column is defined in code as a GridButtonColumn, how can the buttons be removed from a specific cell when a condition is satisfied?  I have tried handling the QueryCellStyle, QueryRowStyle, and QueryButtonStyle events, but I have not been able to determine a process that would remove the buttons.  In the DrawCell event, every attempt appears to remove the buttons from the entire column.  The data source of the Grid is an IEnumerable<DataRecord>.

The Grid Buttons are added to the grid in code similar to the following:

List<CellButton> buttons = [];
 buttons.AddRange(
     new CellButton() { Text = ClientConstant.Buttons.ADD_NEW },
     new CellButton() { Text = ClientConstant.Buttons.MODIFY_EXISTING },
     new CellButton() { Text = ClientConstant.Buttons.REMOVE_EXISTING }
     );
dataGrid.Columns.Add(new GridButtonColumn()
{
    MappingName = ClientConstant.Grids.ACTION,
    HeaderText = ClientConstant.Grids.ACTION,
    Buttons = buttons,
    Orientation = Orientation.Horizontal,
    AutoSizeColumnsMode = AutoSizeColumnsMode.AllCells,
});
private void GrdPayments_QueryRowStyle(object sender, QueryRowStyleEventArgs e)
{
    if (e.RowType.Equals(RowType.DefaultRow))
    {
        if ((e.RowData as ParcelPaymentInformationResponse)!.RemovedOn.HasValue)
        {
            e.Style.BackColor = ColorHelper.FromHtml(SyncfusionConstant.ColorName.WINFORM_WARNING);
        }
    }
}
private void GrdPayments_DrawCell(object sender, DrawCellEventArgs e)
{
    if (e.Column.MappingName.Equals(ClientConstant.Grids.ACTION))
    {
        if ((e.DataRow.RowData as ParcelPaymentInformationResponse)!.RemovedOn.HasValue)
        {
        }
    }
}

Hi Greg,

As you mentioned, If you remove the buttons in Drawcell event it will be removed in the entire column and it is a behavior. As analyzed in the possible ways, SfDatagrid does not have support to remove the button from the specific cell in GridButtonColumn. However you can disable the button in the specific cell. This can be achieved by enabling and disabling in the QueryButtonCellStyle event.

Code snippet to disable button in QueryButtonCellStyle event:

public Form1()

{

 InitializeComponent();

 this.sfDataGrid1.QueryButtonCellStyle += OnSfDataGrid_QueryButtonCellStyle;

}

 

private void OnSfDataGrid_QueryButtonCellStyle(object sender, Syncfusion.WinForms.DataGrid.Events.QueryButtonCellStyleEventArgs e)

{

 if (e.Button.Text == "Button2" && e.RowIndex % 3 == 0)

 {

 e.Style.Enabled = false;

 }

}

I have been able to disable the buttons with the QueryButtonCellStyle event and that works fine.  I was hoping for a method that would remove the buttons.  

Would it be possible to submit an enhancement request to add a "Visible" property to the ButtonCellStyleInfo class?

Hi Greg, 

Currently, we do not have support to remove a button from a specific cell in the GridButtonColumn based on certain conditions. However, we have analyzed and considered your requirement and have logged a feature request for the same.

At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest.

We will provide the feature feedback link by tomorrow.

Note: In the meantime, you can disable the button in the specific cell as per the previously suggested solution.
