c# - How to Use a Tag to Change the Properties of Multiple Items With That Tag? -

i have multiple 6 buttons, when click on each button, change properties, , deactivate other properties in others of same tag.

the code have @ moment doesn't use tags , long winded doing every button click:

private void buttonbritishgas_click(object sender, eventargs e)     {         buttonbritishgas.flatstyle = flatstyle.flat;         buttonbritishgas.flatappearance.bordersize = 3;         buttonbritishgas.flatappearance.bordercolor = color.blue;          buttonedf.flatstyle = flatstyle.standard;         buttonedf.flatappearance.bordersize = 1;         buttonedf.flatappearance.bordercolor = color.white;          buttoneon.flatstyle = flatstyle.standard;         buttoneon.flatappearance.bordersize = 1;         buttoneon.flatappearance.bordercolor = color.white;          buttonnpower.flatstyle = flatstyle.standard;         buttonnpower.flatappearance.bordersize = 1;         buttonnpower.flatappearance.bordercolor = color.white;          buttonscottishpower.flatstyle = flatstyle.standard;         buttonscottishpower.flatappearance.bordersize = 1;         buttonscottishpower.flatappearance.bordercolor = color.white;          buttonsse.flatstyle = flatstyle.standard;         buttonsse.flatappearance.bordersize = 1;         buttonsse.flatappearance.bordercolor = color.white; 

the tag using "supplier" , here code have attempted @ moment:

private void buttonbritishgas_click(object sender, eventargs e)     {          buttonbritishgas.tag = "selectedsupplier";          foreach (control c in controls)         {             if (c.tag.equals("selectedsupplier"))             {                 flatstyle = flatstyle.flat;                 flatappearance etc...;             }         }          foreach (control c in controls)         {             if (c.tag.equals("supplier"))             {                 flatstyle = flatstyle.standard;                 flatappearance etc...;             }         } 

any appreciated!

you have loop recursively inside form's control tree:

    private void changestylebytag(control parent, string tag)     {         foreach (control c in parent.controls)         {             if (c.tag!=null && c.tag.equals(tag))             {                 (c button).flatstyle = flatstyle.flat;                 (c button).flatappearance.bordersize = 3;                 (c button).flatappearance.bordercolor = color.blue;             }             else                 changestylebytag(c, tag);         }     }      private void buttonbritishgas_click(object sender, eventargs e)     {          changestylebytag(this, "selectedsupplier");         changestylebytag(this, "supplier");     }
