c# - How do I call a method that only accepts a parameter that is in another form? -


i have form1 (that runs program) , form2 (that form user input). form2 has function clears user input (textboxes, checkboxes, combo boxes, clears them).

the function looks this:

public void cleartheform(control groupofcontrols) {     foreach (control c in groupofcontrols.controls)     {         if (c textbox)         {             ((textbox)c).clear();         }          if (c.haschildren)         {             cleartheform(c);         }          if (c checkbox)         {             ((checkbox)c).checked = false;         }          label3.text = "";         combobox1.selectedindex = -1;         combobox2.selectedindex = -1;     } }

this works on own. on main form, need call function, should this:

i make instance of form2 call inputform , then:

private void addrecord_click(object sender, eventargs e) {     inputform.showdialog();      if(inputform.addedrecord == true)     {         inputform.addrecord();         inputform.cleartheform(what put in here??);     }                    }

so once record has been added, input form clears , ready record added.

the question above, put in there? how call groupofcontrols in inputform.cleartheform() located in form2 form1?? tried make public control groupofcontrols on top of form2 , leave form1 inputform.cleartheform(control groupofcontorls), saids don't have object reference. if leave blank saids inputform.cleartheform(); not take 0 arguement.

well, if wanted clear all controls in inputform write version of cleartheform() without parameter, , call version with parameter it, so:

public void cleartheform() {     cleartheform(this); // passes controls in form. }

or can call original cleartheform(control) passing reference inputform argument: inputform.cleartheform(inputform).

if want clear controls, i'd write separate parameterless method clarity.

however, useful if want clear controls in inputform.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
