Disable popping up the calendar in a DateTime cell

[BECK]

If I set the Format to "Time" I see no need for the Calendar button to show up in the cell. I basically want a cell that only has time in it. How can I disable showing the calendar button?

Thanks

Hello Beck,

The following example uses the CellEditorInitialized event to format the editor to a time, and then replace the calendar drop down button with the up/down arrows that are needed on a time based editor.

Designer File

namespace RadGridView_Basic_C
{
    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);
        }
