Hello dear.
I want to do following.
There is one dropdownlist on asp.net page.
On selection changed event a new dropdownlist should be created.
And on the each drop down list selection change event a new dropdownlist shold be added.
In Windows Form application i achieved this with the following code.
public partial class Form1 : Form
{
ComboBox c = null;
int y = 10;
public Form1()
{
InitializeComponent();
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
c = new ComboBox();
c.Items.Add("Item 1");
c.Items.Add("Item 2");
c.Items.Add("Item 3");
c.SelectedIndexChanged += new System.EventHandler(this.comboBox1_SelectedIndexChanged);
c.Location = new Point(((ComboBox)sender).Location.X, y = y + 50);
Controls.Add(c);
}
}
It's urgent please help.

Yes, you can do it. But, you need to add the controls before page_load in order for their viewstate to be restored, and thus for events to fire. The other option is to have one or more hidden text controls and to use javascript to store the details of your state there, so that you can always read that and recreate your controls.

The problem is that we don't know how many drop down lists will be created. So how we can dynamically add the drop down list on asp.net page as the selected index change event of another drop down list control occurs.
If a demo is available then it will be a great favour.
Thanks for your time.

OK, this error is officially driving me insane. I've been at it for a few hours, googled, tried the suggestions I've found and nothing works.
This used to build OK and only some greater power can discern why it stopped. Mind you, I haven't touched this code for months.
This is the partial code in the code behind for the web service:
[WebService(Namespace = "http://tempuri.org/", Name = "AddBlogEntry")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
public class AddBlogEntry : System.Web.Services.WebService
{
[WebMethod]
public bool AddEntry(string blogEntryData, string blogEntryTitle, string blogEntrySubTitle)
{
try{
...
This is the line in the asmx page:
<![CDATA[<%@ WebService Language="C#" CodeBehind="AddBlogEntry.asmx.cs" Class="McdnWebservices.AddBlogEntry" %>]]>
And this is the error that I get:
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not create type 'McdnWebservices.AddBlogEntry'.

Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053
Any clues?

hi,
I am convert in my project asp 1.1 to 2.0. if i am change in my asp 2.0
project that is a have add in one button control
Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
the error is has multiple definition with identical signtures.
Please help me how i am add button in my project.
Thank you,
|
|
|
|
|
why do you have a button called button1 ?
Are you saying this code already existed, or that you;re adding it ? Did you check to see if you do have two methods with the same signature ? I assume the compiler is telling the truth. Search your whole project for that method, it's possible that where it lives changed between 1.1 and 2.0.

Whose performance is better with microsoft dotnet oracle or sqlserver
|
|
|
|
|
I think that it depends how we designed the database structure and code.

It depends who you ask - Oracle users will claim oracle, SQL Server users will claim SQL Server 
To be honest, a more lot depends on the database design than the vendor.

My appn. was working well. Suddenly It throws, the error in web config file called "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS". I've never changed anything in my webconfig file. What the problem will be?
Tnx in adv.

If you have any backup folder (with a web.config) in your web application folder, you have to move that backup folder outside your application folder.
