ASPxGridView - How to enable editing a column/cell in Batch Edit Mode when filed is custom property editor

Hi Team,
There is a small issue with editing a fields in ASPxGrid in BatchEditMode.
I have applied a Custom Property Editor for all decimal fields in my application. When i am using Inline edit it's working fine. But after upgrading to 15.2 batch edit mode, these Decimal fields are disabled for editing.

I am using my sample code like this in my Custom Editor:

C#
protected override WebControl CreateViewModeControlCore()
{
    ASPxTextBox tb = CreateTbControl();
    tb.Enabled = false;
    return tb;
}

protected override WebControl CreateEditModeControlCore()
{
    return CreateTbControl();
}

private ASPxTextBox CreateTbControl()
{
    ASPxTextBox tb = new ASPxTextBox();
    tb.DisplayFormatString = "{0:c2}";
    tb.MaskSettings.Mask = "$<0…9999999999999g>.<00…99>";
    tb.MaskSettings.IncludeLiterals = MaskIncludeLiteralsMode.DecimalSymbol;
    return tb;
}

How to enable them? Any help… Thanks in advance.

Hello,

When a custom property editor is used for a column, this editor's controls are added to the column through custom templates - DataItemTemplate and EditItemTemplate. The Grid control does not support batch editing for columns where templates are used - this functionality is supported only for editors provided by Data Columns. So, to enable the batch editing functionality, use the built-in property editors in the required columns of your ListView.

To customize inline editors in this case, handle the ASPxGridListEditor.CustomizeGridViewDataColumn event and change the column editor settings (e.g., using the GridViewEditDataColumn.PropertiesEdit and GridViewDataSpinEditColumn.PropertiesSpinEdit properties).

C#
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Web.Editors.ASPx;
using DevExpress.Web;

namespace MainDemo.Module.Web {
    public class HideSpinButtonsController : ViewController<ListView> {
        ASPxGridListEditor gridListEditor;
        protected override void OnActivated() {
            base.OnActivated();
            gridListEditor = View.Editor as ASPxGridListEditor;
            if(gridListEditor != null) {
                gridListEditor.CustomizeGridViewDataColumn += GridListEditor_CustomizeGridViewDataColumn;
            }
        }
        private void GridListEditor_CustomizeGridViewDataColumn(object sender, CustomizeGridViewDataColumnEventArgs e) {
            if(e.Column is GridViewDataSpinEditColumn gridViewDataSpinEditColumn) {
                gridViewDataSpinEditColumn.PropertiesSpinEdit.SpinButtons.ShowIncrementButtons = false;
            }
        }
        protected override void OnDeactivated() {
            base.OnDeactivated();
            if(gridListEditor != null) {
                gridListEditor.CustomizeGridViewDataColumn -= GridListEditor_CustomizeGridViewDataColumn;
                gridListEditor = null;
            }
        }
    }
}

Refer to the following help topic for additional information: Data Columns.

Does this apply to InlineEditMode = Inline or only InlineEditMode = Batch?

Hello Jimmy,

ASPxGridListEditor always uses EditItemTemplate with property editor controls in Inline edit mode. If your custom Property Editor does not work in this scenario, please feel free to create a separate ticket and describe the issue in detail, with code examples or a sample project.
