We are using version 2016.3.1024.40 and i just want to clear the value.  I have tried setting the value = null and that does not work.  Standard controls that would work just fine.  There has to be a simple way to do this.  I have about 20 controls that I need to do this to.  Just want to take the value/text that is displayed and blank it out.

Thanks in advance.

Mark

Hello Mark,

The following article shows how you can clear the value: Set null or empty value.

Should you have any other questions do not hesitate to ask.

Yup tried that and NullableValue is not an option for the version i posted.  I have looked at ALL of Teleriks docs and they are no help.  I need some working code for my version.  Something simple would be preferred.

Hi Mark,

This is working with your version. I have attached a small sample project that shows this.

Hi Mark,

This works with the time picker and the specified version as well (see attached video).

Designer:

 this.dtFirstStart = new Telerik.WinControls.UI.RadTimePicker();

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

// 
            // dtFirstStart
            // 
            this.dtFirstStart.Font = new System.Drawing.Font("Verdana", 9.75F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
            this.dtFirstStart.Location = new System.Drawing.Point(7, 41);
            this.dtFirstStart.MaxValue = new System.DateTime(9999, 12, 31, 23, 59, 59, 0);
            this.dtFirstStart.MinValue = new System.DateTime(((long)(0)));
            this.dtFirstStart.Name = "dtFirstStart";
            this.dtFirstStart.Size = new System.Drawing.Size(106, 21);
            this.dtFirstStart.TabIndex = 50;
            this.dtFirstStart.TabStop = false;
            this.dtFirstStart.Text = "radTimePicker1";
            this.dtFirstStart.ThemeName = "Office2010Blue";
            this.dtFirstStart.Value = null;

((Telerik.WinControls.UI.RadTimePickerElement)(this.dtFirstStart.GetChildAt(0))).ClickMode = Telerik.WinControls.ClickMode.Press;

//this does not work.  Does nothing

 private void btnClearThirdShift_Click(object sender, EventArgs e)
        {            
            dtFirstStart.Value = null;
        }
