did you complete the first level, that City and Country read from Database and bind it to dropdown list ? if yes then do one thing, on selectetd index changed of City name ,call the same function that you have used for load country name first time. just change the query as ,
Select Country from mydB where City='"+ ddlCity.text + "'
hope this will help you. if you have any doubts you can ask me .
cheers,

Yes.DropDownList has SelectedValue property,
ddl.SelectedValue="Ahmedabad"; // if value is cityname
OR
ddl.SelectedValue="YourCityID"; //if value if cityID

Have you filled the Country DDl first in Update Form??
Then do following:
1. Run a query and get CountryID or CountryName What ever you want from Database for that perticular user. (Lets Take ID in this case)
2. write this code after getting CountryID:
int intCountryID = .....;
for(int i=0;i<(ddlCountry.Length);i++)
{
if(ddlCountry[i].Value == intCountryID)
ddlCountry.SelectedIndex = i;
}
3. Write this code into ddlCountry's SelectedIndexChanged property:
.
.
.
. here and load all cities into ddlCity
.
int intCityID = .....;
for(int j=0;j<ddlcity.length);j++)>
{
if(ddlCity[i].Value == intCityID )
ddlCity.SelectedIndex = j;
}
4. Bingo!!! Problem Solved
Got it?????????

Just one line can do this.
ddlCountry.SelectedValue=intCountryID.ToString();

That detailed code was to make Sandeep understand the basic procedure. Even I can imagine and understand what u wrote. but we have to explain all in simple language to that man. do u think Sandeep will digest as easily your line compare to my code??????????
Just wanted to teach how to think to our Juniors!!!

Here you will get lot of replies to your question
but i bet you are not going to learn anything as you are not showing any efforts to tackle the problem.
It seems that you are in learning phase for which you should always take help from google, there are n number of articles for developers which are in initial stage.
Please try to learn first then if you stuck with any issue (atleast put some efforts )then ask question here that's the meaning of any forum.
This is how you are going to learn 
Thanks and Regards

I think your update form's city dropdownlist and country dropdownlist contains list of city and country.And you want the particular city and country to come as selected.
For that by using the select query you take the value to the form.You assign that to a string variable.For example the city value is assigned to strCity and country to strCountry.If the city's dropdownlist is DropDownList1 and country's is DropDownList2.
Then you can use the following code
if (DropDownList1.Items[0].Text == strCity)
{
DropDownList1.SelectedItem.Text =strCity;
}
else
{
DropDownList1.Items.Insert(0, strCity);
}
if (DropDownList2.Items[0].Text == strCountry)
{
DropDownList2.SelectedItem.Text =strCountry;
}
else
{
DropDownList2.Items.Insert(0, strCountry);
}
Hope This Code Help You

I want to use listbox as Select ListBox.
I mean select one item from left side and add it to the other side.
I've used updatepanel for this purpose.
I have a minor problem:
in the code behind, it shows that it's doing its job correctly but the UI result is different.
and it happens irregularly.
I mean sometimes it works correctly.

Bardia

This is the problem due to update panel.
Bardia Shahini wrote: I mean select one item from left side and add it to the other side.
How did you add items from one to another ? using any Button or ??
Bardia Shahini wrote: I've used updatepanel for this purpose.
How many update panel did you used ? if both list box are in different update panel then you should update both update panel after event fire.
if you are using button to navigate items, update both update panel on button Click, For that you have to set updatemode="Conditional" and on button click myupdatepanel.update()
hope this will helps you . if you have any dobts , then put your both Aspx and codebehind section.
cheers,
Abhijit

Thanks for reply,
I've used 4 buttons for transferring items from one side to the other side
MoveAll
MoveSelected
RetrunAll
ReturnSelected
and I've used a single Updatepanel.
this is my aspx code:
<updatepanel id="UpdatePanel1" runat="server" rendermode="Inline" updatemode="Conditional">
<contenttemplate>
<asp:listbox id="lstSource" runat="server" xmlns:asp="#unknown">
| <asp:button id="btnMoveAll" runat="server" text=">>" onclick="btnMoveAll_Click" xmlns:asp="#unknown">
<asp:button id="btnMoveSeleted" runat="server" text=">" onclick="btnMoveSeleted_Click" xmlns:asp="#unknown">
<asp:button id="btnRemoveSelected" runat="server" text="<" onclick="btnRemoveSelected_Click" xmlns:asp="#unknown">
<asp:button id="btnRemoveAll" runat="server" text="<<" onclick="btnRemoveAll_Click" xmlns:asp="#unknown">
| <asp:listbox id="lstDestination" runat="server" xmlns:asp="#unknown">
|
<triggers> <asp:asyncpostbacktrigger controlid="btnMoveSeleted" eventname="Click" xmlns:asp="#unknown">
<asp:asyncpostbacktrigger controlid="btnMoveAll" eventname="Click" xmlns:asp="#unknown">
<asp:asyncpostbacktrigger controlid="btnRemoveAll" eventname="Click" xmlns:asp="#unknown">
<asp:asyncpostbacktrigger controlid="btnRemoveSelected" eventname="Click" xmlns:asp="#unknown">
and this is my CodeBehind Code:
protected void btnMoveAll_Click(object sender, EventArgs e)
{
if (lstSource.Items.Count > 0)
{
int count = lstSource.Items.Count;
for (int i=0; i < count; i++)
{
lstDestination.Items.Add(lstSource.Items[i]);
}
lstSource.Items.Clear();
}
UpdatePanel1.Update();
}
protected void btnMoveSeleted_Click(object sender, EventArgs e)
{
if (lstSource.Items.Count > 0 && lstSource.SelectedValue != string.Empty)
{
lstDestination.Items.Add(lstSource.SelectedItem);
lstSource.Items.Remove(lstSource.SelectedItem);
}
UpdatePanel1.Update();
}
protected void btnRemoveSelected_Click(object sender, EventArgs e)
{
if (lstDestination.Items.Count > 0 && lstDestination.SelectedValue != string.Empty)
{
lstSource.Items.Add(lstDestination.SelectedItem);
lstDestination.Items.Remove(lstDestination.SelectedItem);
//SetListBoxIndexes();
}
UpdatePanel1.Update();
}
protected void btnRemoveAll_Click(object sender, EventArgs e)
{
if (lstDestination.Items.Count > 0)
{
int count = lstDestination.Items.Count;
for (int i=0; i < count; i++)
{
lstSource.Items.Add(lstDestination.Items[i]);
}
lstDestination.Items.Clear();
}
UpdatePanel1.Update();
}
