Solution 1

You compare your 'selectinsexval' with the contents of a not assigned (new) Integer-Array.
Inside this Array, all elements which are not assigned are ==0.
If you select your first Item inside your Combobox it has the Index==0. So it works.
The next Item has Index==1 ...

Did you get what I mean ...?
Perhaps comparewith constants ...

faizyab 2009 8-Jun-15 1:56am

Sir i tried as you are saying to me. i hope it will work if i will assign arr[0]=Comboxbox1.SelectedIndex,arr[1]=Comboxbox2.SelectedIndex,arr[2]=Comboxbox3.SelectedIndex
Did it your mean ????

Vipin Patil 8-Jun-15 2:00am

your arr variable is not assign with any value it is empty array
and you are checking selectinsexval value to arr's value

Vipin Patil 8-Jun-15 2:04am

no you can directly check selected index with int values like
if(selectinsexval == 1){}
else if(selectinsexval == 2){}

or
Switch(selectinsexval)
{
case 1:your code; break
case 2:your code; break
}

still not workiing

Vipin Patil 8-Jun-15 2:30am

Why are you using arr you can directly check like this

private void courtnamelist_SelectedIndexChanged(object sender, EventArgs e)
{
int selectinsexval = courtnamelist.SelectedIndex;

if (1==selectinsexval)
{
supremecourtlist.Visible = true;
button8.Visible = false;
}
else if (2 == selectinsexval)
{

districtcourtlist.Visible = true;

}
else if (3 == selectinsexval)
{
heighcourtlist.Visible = true;
}
}
