Tabbing in a loop through a winform

I have an application where I have several forms. Its a C# windows-form based application build in .NET 4.O. I have several forms where the user enters the data. There are grids where data is displayed and whole lots of controls on the form. Believe me! its a mess of so many controls. I have to setup the TabIndex for each control. I have literally disabled the TabStop property of certain controls I don't want to be tabed into it. However, still once I go through the order I want, I TAB it, and it works but once it reaches the last box then it takes 3-4 times more tabbing to get to the first field. I tried disabling the TabStop property for the controls I don't want. But I think there might be certain controls that I don't see but they might be included in the Tab property. My question is that is there any way that I can set the TabStop property of all the controls on the winform to false and then set it to true for the controls I want to include only.

I also open to if there is any other way I can implement this?

If further explanation is needed, let me know!

I have attached a picture thats the order I want and then loop back but somehow its not working. Just in addition there is also two panels in the form and I have disabled their TabStop property to False. enter image description here

Solution

  • One simple explanation is that you lost a control underneath another one that overlaps it. Or it is located beyond the edges of the Form. A good tool to find it back is View + Other Windows + Document Outline.

    If that doesn't help then diagnose it by adding a Label and a Timer. Write the Tick event handler like this:

    private void timer1_Tick(object sender, EventArgs e) {
    if (this.ActiveControl != null) label1.Text = this.ActiveControl.Name;
}
