I could use the ASP.NET AJAX Framework but then i would never learn what is going on in the background. Call me ole fashioned, but i like to know how things work and customize it accordingly. Dont get me wrong, the whole ASP.NET AJAX Framework is terrific, but i want tobe able tocreate all that on my own. Can you give me a simple sample on how touse this interface?

I don't have any code to hand. As I previously stated, the MSDN documentation contains all the information you need, including a sample[^] implementation.
I still think you are better off using the ASP.NET AJAX framework. Writing the Javascript plumbing code to get the client-side callback stuff to work is pretty tedious and takes up time that could otherwise be spent doing more interesting stuff. The AJAX Control Toolkit download comes with source, so you can look at the implemention of the AutoComplete control and modify the code if you need to.

Hi,
I have a categories which can have multiple child categories, and each child category can also have multiple child categories.
I want to display all the categories with their child categories right down to the lowest level hierarchy like:
Level 1
Level 1.1
Level 1.1.1
Level 1.1.2
Level 1.1.2.1
Level 1.2
Level 1.2.1
Level 1.2.2
Level 2
etc. etc. etc.
Is their a .NET control that does this? If not how would I go about it? Any sample articles would be appreciated. Does the repeater control not do something like this?
Regards
Brendan

Probably some kind of custom treeview might do the trick.

What have you tried?
It isn't acceptable to post messages on the forums asking for code without demonstrating that you have made a serious attempt to solve the problem yourself. I suggest you search Google and buy a book.

Agree totally. What is so hard about trying and getting stuck, then asking?

You know how to get the data from database, right? so, get the data from database. loop the recordset and write the data on your page... but if you are looking for some reports like crystal report, I think it is not available in ASP.

Of COURSE it is.
Are you using ASP, or ASP.NET ? This is the ASP.NET forum, and you said ASP.

Can we Write GET,Set Property in WebServices?
I create One Property .in Webservice...
I Want to Access that Property in Client App...
Is it Possible???

When you want to expose your custom made business objects through a webservice interface, and you want them to bind with a DataGrid, you have a problem that the generated proxy class exposes fields instead of properties. A possible solution is to generate at runtime, a wrapper for your proxy class.

Treat a web method as a property in a web-service. Web Methods will expose all your objects to your client for consumption, but make sure that you declare those objects in your service class in order to expose them as return objects.

It is possible - with limitations. Effectively a property is just a set of special methods marked as get_ and set_ such as:
private int _item;
public int get_Item()
{
return _item;
}
public void set_Item(int value)
{
_item = value;
}A limitation though is that a web service is stateless, so you need to be careful how you maintain the state.

just want to redirect? then, use response.redirect to redirect your page to https:

You just do a redirect.

Some users are secure and some are not ? What on earth for ?
The trick with https is, all relative urls remain https, so you need absolute urls to break out of it. Otherwise you can create a https section on your site and find that people stay in https for the rest of their visit.

Why are you reposting? Your previous thread is only a few hours old. Spamming the forum with the same question over and over will only annoy people.

Hello,
I have 2 dropdownlist A and B
When I select from A, I get the B list according to A selection.
I done it implementing callback process.
This work fine.
In addition, I have a button in my form that after clicking it , I fill a gridview according to A nd B selections.
The problem is that after clicking on the button, the B dropdownlist is empty, the postback action empty my B dropdownlist.
How can I fix this problem.
Here is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim dt As DataTable = GetCategory()
Dim dv As DataView = dt.DefaultView
cmbCategory.DataSource = dv
cmbCategory.DataTextField = "PROFCAT"
cmbCategory.DataValueField = "PROFID"
cmbCategory.DataBind()
cmbCategory.Attributes.Add("onchange", "GetChildren(this.options[this.selectedIndex].value,'ddl');")
Dim callBack As String = Page.ClientScript.GetCallbackEventReference(Me, "arg", "ClientCallback", "context", "ClientCallbackError", False)
Dim clientFunction As String = "function GetChildren(arg,context){ " + callBack + "; }"
Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "GetChildren", clientFunction, True)
End If
End Sub
Public Sub RaiseCallbackEvent(ByVal eventArgument As String) Implements System.Web.UI.ICallbackEventHandler.RaiseCallbackEvent
Dim dt As DataTable = GetSubCategory(eventArgument)
Dim dv As DataView = dt.DefaultView
Dim sb As New StringBuilder()
For i As Integer = 0 To dv.Count - 1
sb.Append(dv(i)("SUBPROFID"))
sb.Append("^")
sb.Append(dv(i)("SUBPROFCAT"))
sb.Append("|")
Next
_callbackArg = sb.ToString
End Sub
Public Function GetCallbackResult() As String Implements System.Web.UI.ICallbackEventHandler.GetCallbackResult
Return _callbackArg
End Function
Private Function GetCategory() As DataTable
Dim dt As DataTable = DirectCast(Cache("Category"), DataTable)
If dt Is Nothing Then
Dim connection As New OleDbConnection(connectionstring)
Dim command As New OleDbCommand("SELECT PROFID, PROFCAT FROM PROFESSION ORDER BY PROFCAT", connection)
command.CommandType = CommandType.Text
Dim da As New OleDbDataAdapter(command)
dt = New DataTable
Try
connection.Open()
da.Fill(dt)
Cache.Insert("Category", dt, Nothing, DateTime.Now.AddHours(6), TimeSpan.Zero)
Finally
connection.Dispose()
command.Dispose()
da.Dispose()
End Try
End If
Return dt
End Function
Private Function GetSubCategory(ByVal eventargument As String) As DataTable
Dim connection As New OleDbConnection(connectionstring)
Dim command As New OleDbCommand("SELECT SUBPROFID, SUBPROFCAT FROM SUBPROFESSION WHERE PROFID=" & eventargument, connection)
command.CommandType = CommandType.Text
Dim da As New OleDbDataAdapter(command)
Dim dt As New DataTable
Try
connection.Open()
da.Fill(dt)
Finally
connection.Dispose()
command.Dispose()
da.Dispose()
End Try
Return dt
End Function
Protected Sub cmdSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdSearch.Click
'When clicking this button, postback occur and B dropDownList is beeing empty
end Sub
'''''''''''''''''''''''''
// <!CDATA[
function ClientCallback(result, context){
var subcategory = document.forms[0].elements['<%=CmbSubCategory.UniqueID%>'];
if (!subcategory){
return;
}
subcategory.length = 0;
if (!result){
return;
}
var rows = result.split('|');
var option = document.createElement("OPTION");
option.innerHTML = "בחר...";
option.value= "-1";
option.style.color = 'blue';
subcategory.appendChild(option);
option= document.createElement("OPTION");
option.innerHTML = "הכל";
option.value= "0";
option.style.color= "purple";
subcategory.appendChild(option);
for (var i = 0; i < rows.length-1; ++i){
var values = rows[i].split('^');
var option = document.createElement("OPTION");
option.value = values[0];
option.innerHTML = values[1];
subcategory.appendChild(option);
}
}
function ClientCallbackError(result, context)
{
alert(result);
}
// ]]>
Thank you for help

You should only post the code where you suspect the problem is. Not the whole thing.

Thank you!
I though that the code may be useful for other users who want to use callback.
So, here is my problem:
I have 2 dropdownlist A and B
When I select from A, I get the B list according to A selection.
I done it implementing callback process.
This work fine.
In addition, I have a button in my form that after clicking it , I fill a gridview according to A nd B selections.
The problem is that after clicking on the button, the B dropdownlist is empty, the postback action empty my B dropdownlist.
How can I fix this problem.
