    Requirements

    Telerik Product and Version

    ASP.net AJAX 2017 R2

    Supported Browsers and Platforms

    Same as Telerik ASP.net AJAX

    Components/Widgets used (JS frameworks, etc.)

    RadGrid


    PROJECT DESCRIPTION 
    I find that my users do not like checkbox columns very much. I find that they much prefer a Yes/No to be displayed instead as well as being able to select Yes or No when editing. That is why I wrote the GridYesNoDropDownColumn. It's actually quite simple as shown below. I hope you find this as useful as I have!

    public class GridYesNoDropDownColumn : GridDropDownColumn
        {
            #region CTOR
     
            public GridYesNoDropDownColumn()
            {
                this.ColumnValidationSettings.RequiredFieldValidator.InitialValue = "*";
                this.ListTextField = "Value";
                this.ListValueField = "Key";
                this.DropDownControlType = GridDropDownColumnControlType.DropDownList;
            }
     
            #endregion // CTOR
     
     
            #region IMPLEMENTATION
     
     
            /// <summary>
            /// Sets the drop down list's data source
            /// </summary>
            /// <param name="inItem"></param>
            protected override void SetDropDownListDataSource(GridItem inItem)
            {
                GridDropDownColumnEditor editor = (GridDropDownColumnEditor)this.CurrentColumnEditor;
                Dictionary<bool?, string> data = new Dictionary<bool?, string>();
                if (this.EnableEmptyListItem)
                    data.Add(null, "");
                data.Add(true, "Yes");
                data.Add(false, "No");
                editor.DataSource = data;
                base.SetDropDownListDataSource(inItem);
            }
             
            #endregion // IMPLEMENTATION
        }

    Hello,

    Thank you for sharing your specific approach with our community. I've updated your Telerik points as a token of gratitude.

    I just want to insert a general caveat here that using custom controls is beyond our support scope, even when they are inherited directly from Telerik controls:
    http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/inheritance/inheriting-grid-columns

    Another approach to achieve this requirement is to use a GridTemplateColumn:
    http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/columns/column-types#gridtemplatecolumn
