Hi All
I have a DataGrid that is bound at run-time.
Upon the click of the Add, a new row is added to the top and it has textbox control
The DataGrid is bound.
Now, the user fills out the controls and clicks Save at which point I need
to validate.
So, how can this be done programmatically?
Thanks

Hello!
I've tried to search the posts and answers to find a possible answer to my question, but... the search page doesn't seem to work. It just says loading...
Though, that is not the problem. I have a Windows based project inc C# in which i play a sound.
<br />
[DllImport("Winmm.DLL", EntryPoint = "PlaySound", SetLastError = true)]<br />
private extern static int WCE_PlaySound(string szSound, IntPtr hMod, int flags);<br />
i do this and i have a perfectly working sound function.
I would like to "transfer" my windows project to the web and i would really need a way to play a sound, if possible. First of all, i'm not sure what i am looking for and that's why i am asking you.
With thousands of thankies,
drc.

Which means that there is a menu on the top and when the user points to that menu a submenu should appear on mouse over below that.
how can it be done.
if possible please explain with some example or give me any link on the internet site which explains this.
regards
Pranav

Pathan,
I think the secondTextbox, if it is a DIV, you can use the INNERHTML property to see the formatting.
Else, you need to use a RichTextArea controls. There are a plethora of free RichTextArea controls. Your favorite search engine can help you out with one.

Oh my! I broke my web.config by trying out WSE 3.0. For some reason WSE applied its information into the wrong sections of my web app.
At this point, I can either
1) Try to go back to a previous version of the web.config saved in SourceSafe.
2) Try to get a better understanding of what web.config does, and I mean the nitty gritty details here.
3) If such a thing exists, it would be nice to regenerate the web.config file!
I've googled a few pages about web.config yet nothing out there satisfies my deep thirst for understanding web.config. So any info regarding what *exactly* the role(s) of web.config is(are) would be greatly appreciated. From what I'm able to see, the file is a repository of anything and everything, a sort of Registry but without a logical classification system.
Your suggestions, insights and informations are more then welcome!

On the safer side i would suggest to take latest from VSS and recover your web.config. However i would recommand you to grasp thorough understanding of Web.config. It is must if you are into web delopment with asp.net. Internet is the perfact repository for finding information. At the moment i would just say that Web.Config is an organized configuration file which manages your settings and configration on differenct area of web site development.
Following list tells you about different section of configuration file.
- AppSettings : Handles custom settings in the form of name and value pair.
- SessionState: Session related settings.
- ConnectionStrings: An organized place for putting connection strings.
- CustomErrors: Centralized error manangement settings.
- Trace: Centralized location for application tracing.
- Providers: Different provider related settings like MembershipProvider, RolesProvider etc....
- Configuration and ConfigurationSection : Allow creating custom application specific settings....
- Etc...
One more thing
==============
If you install .Net 2.0, IIS gives you a UI for editing web.config file.
Hope this much information if okay for you to get started with the Web.Config

DIVs are better candidates so that the entire table is draggable. Check out the homepage of Inbox.com[^]

Using ASP.Net, C# and mssql, I have created a dataset which is displayed to the user in textboxes. How can I update the dataset and upload the dataset back into the database after the user has modified the textboxes and clicks a button to update the information?
|
|
|
|
|
Update the post back changes for each rows from the textboxes to your dataset
and then use the following code to update the changes to database
OleDbDataAdapter dataAdapter=New OleDbDataAdapter();
OleDbCommandBuilder builder;
dataAdapter = new OleDbDataAdapter("SELECT * FROM" + tableName;, conn);
builder = new OleDbCommandBuilder(dataAdapter);
dataAdapter.UpdateCommand = builder.GetUpdateCommand();
dataadapter.Update(updatedDataSet);
dataAdapter.Dispose();

hi all,
i need help about how to make my web site reads a different language like (arabic) cuz all it gives me just give me question marks instead of the proper characters
|

I have a base page class (BasePage) that all pages on my site inherit.
I also have a database abstraction class (DBClass) that I use to handle all interaction with my database. I have it set up so that when you create an instance of DBClass, it creates a connection to the database, and then all methods on that instance of DBClass use that connection to interact with the database.
So, my idea was to create a public property DB of BasePage that is an instance of DBClass. That way, the database connection will be open and available when the page is loaded and I should be able to make use of it for any calls to the database I might want when loading page content.
So far so good (although if you see any problems with the logic so far, please let me know).
However, now I have the following issue: I have a User Control defined on the page that has to make use of the database. I don't want to create a *new* instance of DBClass inside that user control; it seems like it would be better to just use the public property DB of the main page, that was already created.
But I can't figure out how to reference the page property DB from inside the user control.
Any help or insight would be greatly appreciated.

Cast the Page property to BasePage.

b { font-weight: normal; }

I'm sorry if I'm being stupid, but could you walk me through that?
For example, I have tried this:
Public Class TitleControl : Inherits UserControl
Public Page as BasePage
Public Sub Page_Load(Source as Object, E as EventArgs)
Initialize(Page.DB)
End Sub
Public Sub Initialize(SourceDB as DBClass)
...
End Sub
End Class
And the compiler stops at "Initialize(Page.DB)" and says:
System.NullReferenceException: Object reference not set to an instance of an object.
However, the DB property of the page SHOULD be set to an instance of DBClass, since I do that in the Load() event handler of the BasePage class. And if I understand correctly, the Load() of a page happens before the Load() of the controls inside the page.
I'm probably doing the re-casting wrong, since Im' just guessing at the syntax for that.
Thanks for your help!

After Public Page as BasePage declaration Page is Nothing or null
You can't access Page.DB if Page is Nothing or null and System.NullReferenceException is thrown
|
|
|
|
|
The control has a property named Page. If you declare a variable with the same name, that will override the property. As you never assign any value to your variable, it will always be null.
Just use the property, and cast it to the class BasePage:
((BasePage)Page).DB
