so,can u help me how to do ?

private void combogroup_SelectionChanged(object sender, SelectionChangedEventArgs e)
{

------binded combobox

category ca = new category();
strCurCatGroup = combogroup.SelectedValue.ToString().Trim();
ca.changecategory(strCurCatGroup);//change category is my method

    }

private void changecategory(string strCategoryGroup)
{

switch(---)
{
case "A":
groupbox1.visibility=Visibility.Hidden;
groupbox2.visibility=Visibility.Visible;

--
case "B":

groupbox1.visibility=Visibility.Visible;
groupbox2.visibility=Visibility.Hidden
//groupbox 1 and grpbox 2 contain different controls and i am able to execute the cases properly but the result is not getting.
}

should I set all the groupboxes visible or hidden in pageload ? I have taken grid inside the groupboxes and arranged my controls like textboxes.. If I make groupboxes visible in pageload then while debugging it is showing all the controls in Groupboxes but combo selection change event not working.

thank u .. i will try and reply u

ok Thank you but my form contains so many groupboxes which will be changed as per selecting the combo items.. I appreciate your help. :) Any other method of writing it in codebehind by using a switch case will be helpful.

Thanks for ur reply but i have so many items in combobox by which groupbox visibily will depend.. nearly 10 items in combobox

I need to change my groupbox visibility and I should be able to get those controls in the groupbox1 ,when I change my combobox value in the combobox selectionchange event groupbox2 and its controls should be shown.. line by line execution shows the result i was looking but finally am not able to get the output . This is what I have tried but didn't work for me. Need ur help. if(stringgp1=="group1") { groupbox1.Visibility=Visibility.Visible; groupbox2.visibility=visibility.hidden; } else(something...){}
