I suggest you to make one user control for Country/state selection
In that case you can accomlpish the task as
void ddlCountry_SelectedIndexChanged(object sender, EventArgs e)
{
switch (ddlCountry.SelectedValue)
{
case "0":
ddlState.Items.Add("Delhi");
ddlState.Items.Add("MP");
break;
case "1":
ddlState.Items.Add("Sunae");
ddlState.Items.Add("Seoul");
break;
default:
ddlState.Items.Add("Select");
break;
}
}
In case you want to continue in the same manner as you are doing then try out the following
1. Create a public variable in state.ascx.cs as
public int CountryId = 0;
2. In your function
void ddlCountry_SelectedIndexChanged(object sender, EventArgs e)
{
//Add lines
State objState = (State)FindControl("State1");
objState.intCountryId = ddlCountry.selectedvalue
}
3. In Page load event of state.ascx, check the value of
intCountryid and fill the dropdown accordingly.

1) Not a very good design to expose member variables directly
2) Not a good design either as you are tying these two controls together, one can't used without the other.
A decoupled, and more extensible and reliable design for this situation would use events to communicate between the two user controls.

Also not a good design b/c the items being placed in the list are hard coded instead of coming from a data source. In short, yet another terrible answer given on the ASP.NET forums

i am giving him a example, and examples are not supposed to be bind to datasource.
Now it is to the user who wants to use it and how. He may choose database or may hardcode.
I just picked lines of code from his original source

I am agree with Amandeep . I will bind dropdown by datasource but this is simple example. If my problem solve then I will implement though datasource.

Your problem has nothing to do with the datasource and the "example" provided is a very poor example of how to design the solution.

No you are not giving an example, you are giving a snippet. An example would be fully functional.

Yes, that's a snippet. What you expect from snippet, should it implement a patterns, have complete level of security with properties defined.
OR it should give a idea how you can solve a problem.
Atleast i gave a solution(poor), rather than arguing and criticizing.

Check the posts, so did I, except mine was not so poorly designed.

Is there any reason why the dropdowns are separate user controls? Doesn't really seem necessary, IMO, and is adding to your complexity.
Expose and event on the state control to be called from the country control so your sate dropdown can be populated.

Did you try it or want some one else do for you ?
When select the Checbox, you will get the DataGrid index and then read the row for the corresponding Index.

There some possible reason
1. Resolution are different
2. You are not using proper CSS
3. Your controls are not placed properly on Tables .

Hi There,
I want create tree view at runtime,where user enter parent node name and clicks on add button and parent node get created.Same is the case with child nodes.I don't know how do this.If anybody knows please help.
Thanks.

You can create you own scenario to add nodes to tree.
a possible and easy scenario can be this:
1-if user clicked on create root(parent) ,then you must add node to root of tree with this code:
treeView1.Nodes.add();
2-if user want to add childs, user must first select the parent node , and whenever user clicked on add child you must find current selected node and then add childs with this code:
treeNode1.ChildNodes.add();
the treeNode1 is the selected parent on treeView

Thanks For Reply
I tried the same as you said.But the problem is that when i click on parent node to select, post back occures.How to prevent postback..
Thanks

Get a value to each nodes in tree view and whenever user select a node in selectedindexchanged event you can find TreeView1.SelectedNode.Value and then continue
