RadSpinEditor DataBinding Problem

[Shulla Krous]

Hello,

In our application we use RadSpinEditor with binding.

Now we notice a problem with the binding of the control:

When we update the control by the keyboard, then leave the control by tab, returning to the spinEditor and updating another value, the new value does'nt save – when leaving the control the last value returns.

Looking forward to your reply.        

Here is a sample code:

 

static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
    public class Form1 : Form
    {
        List<Class1> l = new List<Class1>();
        public Form1()
        {
            InitializeComponent();
            l.Add(new Class1());
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.radSpinEditor1.DataBindings.Add("Value", l, "Number");
        }

        #region Windows Form Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.radSpinEditor1 = new Telerik.WinControls.UI.RadSpinEditor();
            this.button1 = new System.Windows.Forms.Button();
            ((System.ComponentModel.ISupportInitialize)(this.radSpinEditor1)).BeginInit();
            this.SuspendLayout();
            //
            // radSpinEditor1
            //
            this.radSpinEditor1.Location = new System.Drawing.Point(77, 39);
            this.radSpinEditor1.Name = "radSpinEditor1";
            //
            // button1
            //
            this.button1.Location = new System.Drawing.Point(90, 86);
            this.button1.Name = "button1";
            this.button1.Text = "button1";
            //
            // Form1
            //
            this.ClientSize = new System.Drawing.Size(262, 121);
            this.Controls.Add(this.button1);
            this.Controls.Add(this.radSpinEditor1);
            this.Load += new System.EventHandler(this.Form1_Load);
            ((System.ComponentModel.ISupportInitialize)(this.radSpinEditor1)).EndInit();
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion

Hello Naama,

 
Thank you for contacting us.

I was able to reproduce the described behavior. You can work around it by calling the SpinElement's Validate method on SpinEditor LostFocus event.

Copy Code

this.radSpinEditor1.LostFocus += new EventHandler(radSpinEditor1_LostFocus);


void radSpinEditor1_LostFocus(object sender, EventArgs e)
{
       this.radSpinEditor1.SpinElement.Validate();
}

Please refer to the modified project. Do not hesitate to contact us if you have other questions.

Hello

I had the same problem, and this workaround has solved it.

Are there any plan to solve this issue in a future release?
