Following data fields are missing in GridViewComboBoxColumn properties: DataSource, DisplayMember, ValueMember.
Also GridViewComboBoxColumn doesn't function when I set these values programmatically in Designer.cs.

Hello Sandi,

These properties are members of the GridViewComboBoxColumn in the latest version of the controls. Please take a look at this documentation which should help.
If you need further assistance, please let me know.

Hello Sandi Markon,

Thank you for writing.

Yes, I confirm that you cannot set these properties when using the Property Builder. However, they are still available when navigating the RadGridView smart tag or when using the Visual Studio property grid. In addition, you can change them with code.

I hope this helps.

Kind regards,
Stefan

Hello,

In this cae you could make the ValueMember the "Name" also. If I have misunderstood your query please let me know.
Regards,
Richard

Hello,

Here is an example for you of binding to a GridViewMultiComboColumn and then getting the changed text.

Form1 Designer File
namespace RadControlsWinFormsApp1
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components;
  
        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
  
        #region Windows Form Designer generated code
  
        /// <summary>

        /// the contents of this method with the code editor.

        private void InitializeComponent()

            ((System.ComponentModel.ISupportInitialize)(this.radGridView1)).BeginInit();
