3 level Cascading combo-boxes ?
Feb 11 2013 6:49 AM
Hi friends
Well here i am looking to create a 3-level combo box cascading filter like in example
Country--> State --> City :
)
Upon selection in countries in combo-box1 respective states should display in combo-box2 the after upon state selection cities should get displayed under combo-box3 . (like drill down).
My work : I used arrays to store states of respective countries & the after i am able to display states in combo-box2 upon country selection in combo-box1 .
Well then after , on selection of req'd state
i was unable to develop the logic to get what i req'd
i.e
I have created country list into combobox-1 (india,usa,australia) in collection & binded event proc of combobox-1 with combobox-2
string[] s1 = { "AP","UP","Delhi"};
string[] s2 = { "chicago","Dallas"};
string[] s3 = { "melborne","sydney"};
string[] s4 = { "AP1", "Ap2" };
string[] s5 = { "UP1", "UP2" };
string[] s6 = { "Delhi1", "delhi2" };
string[] s7 = { "c1", "C2" };
string[] s8 = { "Dallas1" };
string[] s9 = { "M1","M2" };
string[] s10 = { "S1","S2" };
private void Form11_Load(object sender, EventArgs e)
{
comboBox2.Items.Clear();
switch (comboBox1.SelectedIndex)
{
case 0: comboBox2.Items.AddRange(s1);
break;
case 1: comboBox2.Items.AddRange(s2);
break;
case 2: comboBox2.Items.AddRange(s3);
break;
}
So anyone can help me with this bizarre situation :( Need logic to implement this in c#.net windows forms
Thanks in advance
