How to loop through checkboxes in top to bottom design order, or set order

I have this code so far:

foreach (Control child in TableNamePanel.Controls)
{
    if (!(child is CheckBox))
       continue;

    if ((child as CheckBox).Checked)
    {
        Code... 
    }
}

My design has the CheckBoxes on top of each other and the other does matter. I would like to check the first checkbox, then the next and so on. Currently it's starting from the bottom. Any way to change that, or to set the order of how it loops through the control items?

Change your foreach like this:

foreach (Control child in TableNamePanel.Controls.Cast<Control>().OrderBy(c => c.TabIndex))
{
}

This will sort Controls as per TabIndex in the form. You might need to change OrderBy to OrderByDescending.

I think when you loop through they are in order according to they are in desing

but they are not than you can set CheckBox.TabIndex property on checkbox to order it 

var orderedcheckbox= TableNamePanel.Controls.OfType<CheckBox>()
                                       .OrderBy(c => c.TabIndex);

Here I assumeed that tabindex property is avaialbe as per my knowledge this property is available in .net.

Including other solution suggested in comment by @dotNET

TabOrder of your controls at design-time, which he should have anyway. The other way around could be to use the Location property of your checkboxes instead of TabOrder in the above code.
