I have a requirement to set maxlength for Textbox with multiline textmode. The property MaxLength is
not working when the textmode is multiline since it is rendered as textarea. There are couple of ways
explained in forums. I would prefer regular expression than Javascript.
A Regular expression that seems to be working does not work if the page uses master page. It
does not accept carriage return or newline or leading and trailing blanks and throws up error.
^[\s\S]{0,20}$
Have you come across such scenario before? If so, please help.
Thanks

I have a dev IIS server which displays the Printer dialog when I click the printer icon in a crystal report.
When I click the same icon on the production server, "failed to load page" message appears in a box the size of the printer dialog, no dialog.
I can't find help on this anywhere. Can anyone help?

Hi
I am deleting some DataTable records by using ajax and I am showing these DataTable records through Html table in .aspx page using InLine code.
suppose I have 3 rows and deleted 1 row then It should be shown 2 rows only in UI part but It is showing still 3 rows and when I refresh page by using F5 Key in keyboard then It's showing 2 rows that is I want.
but I dont want to show deleted row after deleting.
so how can I refresh page or load page controls again by writing code in .cs file.
because of using ajax It is not refreshing the page.
thanks

You need to delete the row using javascript, if you're writing your own AJAX. If you're using ASP.NET AJAX, you should be able to make the grid refresh using AJAX.

Yesterday, I started creating my web service, and essentially, I have a few projects:
-web service project
-application that calls web service web methods
-common class library
From the application, I added a web reference to the web service in the web service project. Today, when I try to update it by right clicking on the web reference, and then going to "Update Web Reference", I get the following error:
"There was an error downloading 'http://localhost:2276/NewWebService.asmx'.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:2276
I'm not too sure why it was working fine yesterday but not now. Is there something that I need to restart, perhaps?
Thanks.

Is the web service running? Was there any firewall changes since yesterday?

Isn't Visual Studio supposed to do this for you?
Under the web tab for the web service project, I have it set to Use Visual Studio Development Server, and have it assigned to that specific port. I don't know if I have to actually "run" anything to run it though.
EDIT: So after hearing you mention that, I just tried to run the web service project itself... and it seems like you have to do that in order to get anything started.
In the meantime though, I have another question about web services and web methods (but I'll just reuse this existing thread).
I have a web method that takes in a class WebObject (something that I created).
public class WebObject
{
public WebObject(int x, int y, int z)
{
this.x = x;
this.y = y;
this.z = z;
}
private WebObject()
{
}
public void SetX(int x)
{
this.x = x;
}
int x;
int y;
int z;
}
The web method, looks like this:
[WebMethod]
public WebObject AnalyzeObject(WebObject obj)
{
return obj;
}
What's happening though, is that behind the scenes, in some Reference.cs file generated by this web service, the WebObject is being transformed into this:
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.1433")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")]
public partial class ODPOObject {}
This new empty class makes it so that I cannot call the web method with my int x, int y, int z constructor, and if I attempt to create THAT WebObject, it complains that I'm passing in the wrong type. I don't understand this concept at all... would anyone be able to please clarify?

When you run the web service from VS, yes. But without VS, you need to have it in IIS. At least I think so ( I use the casini web server and it works fine there )...

Since you already replied, and I was a little late in editing, I'll add the other part of my last post to this reply:
I have a web method that takes in a class WebObject (something that I created).
public class WebObject
{
public WebObject(int x, int y, int z)
{
this.x = x;
this.y = y;

}
private WebObject()
{
}
public void SetX(int x)
{
this.x = x;
}
int x;
int y;
int z;
}

Strange! Code shows your WebObject class is not marked as serializable. To pass the object to webservice, it should be marked as [Serializable]

Hi All,
I am very new to ASP and need to create a simple dynamic image gallery wherein when the user clicks on the menus (collapsible kind) and the respective image shows up with the title and text. I could do this in simple HTML but then would have to create 20-30 pages.
Is there any way we can do this dynamically through ASP so on the same page all the variables are passed and the image/text changes accordingly. Hopefully this won't require any server side scripting?
I have uploaded a zip file here having the sample pages: http://www.filedropper.com/gallery_1
Thanks,

Yes you can do it using asp but i highly doubt that anyone on this site will give you the source code for it. unless you pay them.

Do you mean ASP or ASP.NET ?
sannysmith wrote: . Hopefully this won't require any server side scripting?
Well, if it doesn't, then it would end up being pure HTML. What do you think ASP.NET code is ?
It sounds to me like you're not clear at all on what ASP.NET is. You should buy a book and work through it. Yes, your best bet is to use a control like a gridview or repeater and writing code that pages and displays your images.

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.
