You can try to enable DoubleBuffering ont he form, but, this is probably not going to fix your problem either. You have to keep in mind that redrawing controls all the time (while you move the grid) is expensive. The more controls you have, the longer the redraw is going to take.

Why bold the entire post?

There are plenty of ways to do these things. Assuming you are speaking of web project, you can do this through the validation controls available. You can have a regular expression validator to do this.

In case of windows forms, use Validating event of the textbox to check text length.

No, a RegEx can be used to do this too. Though, there are other, lighter weight methods to use. If you need to do further validation, RegEx would probably be the way to go.

You can have a hidden html control in your page and share the value through that between client and server side.

you can share this value via hidden control as d@nish said else if you really want to call C# method from javascript then call it like this

<%# serverMethod() %>

You can easily call server side static method, pass some value to it and get the returned value on your page without page postback.
You can write a static Method in your Code-File with:

[System.Web.Services.WebMethod]
public static string MyMethod(string value)
{
    return SomeString;
}

Use Script Manager with PageMethods Enabled.

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"/>

Now you can call your server side method with:

PageMethods.MyMethod(valueToPass, ChangeDDLValue, EnableDDL, dest);

for details please go Google about Ajax PageMethods.

Hope this will help

Hi Thanks a lot,

I am using windows application which adds the scripts dynamically using BHO object and identifies the click even of the link.and actually i cant create the files in local disk from javascript(because of the security issues) so i thought of calling a c# method. then i realized that it cant be done.but we can call a webservice which can manipulate my data from javascript.

Once again thanks for the solution.

Hitting the database every time the user changes cell value will not be a great idea. I suggest to have a save button or something of that sort in your form. On click of that button you can update the values back in the database. You can find lots of examples for saving data back to database on web.

Not exactly. Let the user make changes in the values. And when he/she is done, have a save button to send the updated data back to database. You will need to handle the click event of the button and update the data in your database.

As far as sample code is concerned, this is a bit trivial thing. So, a quick search with correct keywords would give a lot of samples to you.

Outlook 2003 - Display Custom Form/browser in right pane :confused:

Hi guys,

I have a requirement to look at extending functionality of a custom Store. The store contains a tree, and what my client needs to happen is that once a folder is selected then either a VS form containing a web control, or a browser, is displayed filling the right hand pane of the screen pointing at a custom page on their intranet.

I am struggling to find if this is possible within Outlook 2003 and where to start looking.

Any help much appreciated.

Thanks

Your problem description implies this is a web issue; could you clarify what this has to do with Outlook?

Sorry, I'm not sure I understand what you are trying to do. Can you explain what code you are using and how it interfaces with Outlook?

Difference between using StringCollection and List<string></string>

Hi,

I know generics had come after StringCollection, but is there any major difference why we should go for List<string> and not the other...or vice-versa..

Regards,
Priya.

There is a discussion on MSDN about just this topic here:
http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/56a0c1d9-55d9-4b61-876d-2d633b05b602[^] One of the things that is mentioned immediately is that the performance of interating over List<string> is quicker than the collection you mention.

I'd also add that, technically, Collections are unordered whereas with a List the ordering is important.
