Bug with SelectNextControl

[Troopers]

Hi,

The method SelectNextControl of the base class control doesn't work with the Krypton Toolkit controls.
I have created a form with a Krypton panel with the dock property to Fill
Then add this code :

Code: Select all

   public partial class Form1
   {
      public Form1()
      {
         InitializeComponent();

         // Create a textbox
         KryptonTextBox ktbTextBox = new KryptonTextBox();
         ktbTextBox.Name = "Control1";
         ktbTextBox.Text = "";
         ktbTextBox.Location = new System.Drawing.Point(3, 20);
         ktbTextBox.KeyDown += new KeyEventHandler(TextBox_KeyDown);
         ktbTextBox.TabIndex = 1;
         kpPanel.Controls.Add(ktbTextBox);

         ktbTextBox = new KryptonTextBox();
         ktbTextBox.Name = "Control2";
         ktbTextBox.Text = "";
         ktbTextBox.Location = new System.Drawing.Point(3, 60);
         ktbTextBox.KeyDown += new KeyEventHandler(TextBox_KeyDown);
         ktbTextBox.TabIndex = 2;
         kpPanel.Controls.Add(ktbTextBox);

         ktbTextBox = new KryptonTextBox();
         ktbTextBox.Name = "Control3";
         ktbTextBox.Text = "";
         ktbTextBox.Location = new System.Drawing.Point(3, 100);
         ktbTextBox.KeyDown += new KeyEventHandler(TextBox_KeyDown);
         ktbTextBox.TabIndex = 3;
         kpPanel.Controls.Add(ktbTextBox);
      }

      /// <summary>
      /// Occurs on control key down
      /// </summary>
      /// <param name="sender">Event sender</param>
      /// <param name="e">Event arguments</param>
      private void TextBox_KeyDown(object sender, KeyEventArgs e)
      {
         // If it's the ENTER key
         if(e.KeyCode == System.Windows.Forms.Keys.Enter)
         {
            // Get the current control
            KryptonTextBox cControl = ((KryptonTextBox)sender);
            // Set focus on the next control, so perform the validating event on the current control
            cControl.Parent.SelectNextControl(cControl, true, true, false, false);
            
         }
      }
   }


The focus must pass to the next control when ENTER is pressed, It doesn't work
If i replace KryptonTextBox by TextBox, it works

The complication is that the KryptonTextBox, along with some of the other Toolkit controls, the actual KryptonTextBox is just a container that has inside it a standard TextBox for the text drawing. So when you SelectNextControl specifies False for the nesting of controls it means it will not find that embedded TextBox inside the KryptonTextBox itself. Hence the problems you have. I have added a TextBox and a KryptonTextBox to a form and found the following settings would then work for it...

Code: Select all

        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == System.Windows.Forms.Keys.Enter)
            {
                TextBox cControl = ((TextBox)sender);
                cControl.Parent.SelectNextControl(cControl, true, true, true, false);
            }
        }

        private void kryptonTextBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == System.Windows.Forms.Keys.Enter)
            {
                KryptonTextBox cControl = ((KryptonTextBox)sender);
                cControl.Parent.SelectNextControl(cControl.TextBox, true, true, true, false);
            }
        }

Ok, thanks, It's work
