And did you debug the Bind_SearchBox method when you call it from your javascript? Exception must come from somewhere.

Yes i have debugged it and i realized that when i enter the Function , when it goes to this two lines

RadPanelBar1.Items.Clear();
RadScheduler1.Appointments.Clear();

and this one

RadPanelItem pane = RadPanelBar1.Items.FindItemByText(PanelClass);

it goes to the finally block and exit the loop. in IE the debug gives me nothing but in Firefox after the Finally then i get the error i sent you.

The reason exception is thrown is that the View you create doesn't go the regular page lifecycle (I assume the View is your ascx/aspx). Youd didn't call Init, Load or DataBind or whatever event you're filling your controls with data in.
As I said. Try redesign your solution, so it uses postback. Tell me, why you're using javascript and maybe I'll be able to give you a hint.

Good Day

You are Right the View is the Class name of the page aspx and i used javascript because i wanted to handle the keyPress event of the textbox

function keyPress() {
    var tb = document.getElementById("<%=txtsearchid%>");
    if (tb.value.length == 2) {
        PageMethods.Getadata(tb.value, myFunction(tb.value));
        ToggleCollapsePane();



    }
    return false;
}

and take the value that has been entered on key-press and execute the function.

Thanks

OK, so look at the HTML generated by your site. The textbox, that you have you event attached to should have its change event set. (I assume, the textbox you're fighting with right now is the same.) Set the same value for the keyPress event of the textbox and it should work.

OK. At last I have Visual Studio to prepare an answer Wink | ;-)

<asp:TextBox runat="server" ID="text" OnTextChanged="Bind_SearchBox" onkeyup="this.onchange();" AutoPostBack="true" />

AutoPostBack="true" is required for this to work.

Good Day

Thank you for your kind reply.

i have changed my textbox from this

<asp:TextBox ID="txtsearch" runat="server"  Font-Size="X-Large" onkeypress="keyPress()"  Height="40px"
                               Width="650px"></asp:TextBox>

to this

<asp:TextBox runat="server" ID="txtsearch" OnTextChanged="Bind_SearchBox" Font-Size="X-Large" Height="40px" Width="650px" onkeyup="this.onchange();" AutoPostBack="true" />

and i get an Error that says

Error	4	No overload for 'Bind_SearchBox' matches delegate 'System.EventHandler'	C:\Pilot Project\View.aspx	99

Thanks

Yeah, my mistake. Add method

protected void Bind_SearchBox(object sender, EventArgs e)
{
    if(sender.Equals(txtsearch))
    {
        Bind_SearchBox(txtsearch.Text);
    }
}

SQL Server Load Balancing with ASP.Net

Hi
I'm running couple of SQL Server instances in two different instances, Instance A is the master which replicates the data to Instance B. Im running Transaction Based replication, which working well.

Now I want to route the WRITE (Insert, Update, Delete) calls from my ASP.Net application to Instance A and READ (Select) calls to Instance B?

Is there any load balancing mechanism available to do this?

Thanks

C# forum is probably not the correct place for this, I doubt if the database forum will be any better but I would try there. You may be better served by using a dedicated database site - SQLServerCentral.com comes to mind. This really is a DBA type question (rather than a developer question).

Have you tried anything?

The databases only have replication running between them right? So that means that the two databases are distinct entities that can be connected to using separate connection strings. If your application has a dedicated DAL, all the change you need to make is have two separate methods that open a connection, something like

OpenConnectionForWrite()

OpenConnectionForRead()

and your code can call the appropriate method depending on whether it's reading or writing.

How often do you "Build" a project during development?

I would like to know how often you all build and run a project during development. As far back as I can remember, when I first started programming (C++ with the Dev-C++ IDE) I find myself building/running a project quite often. Usually every time I add something new or fix a problem in the code.

Is there some sort of general practice for how often you should do this? Or does that not matter? BTW, I am referring to developing on a single machine. I don't have any experience in a team environment and I have never used any kind of source control.

I build all the time. When I add 10 lines of code, I build, run, test and fix. When I change a few lines, ditto. I make sure my project can always be built, and all new/modified code gets tested right away.

I used to build the component that I work and it's dependencies frequently. But I usually won't build the whole application all the time as it takes more time. On the current project we have a continuous integration server available which will build the whole project once the code is checked in.

Build architecture for C++ projects and C# projects are different. C++ uses incremental approach and only those files that are modified gets compiled. This is a huge time saver after the initial compile. In .NET (except C++/CLI), this is handled at the project level. So if any of the files got modified in the project, VS will compile the whole project rather than just one file. So improper project organization will lead into longer build time.

Build early, and build often.
It serves two purposes:
a) It ensures that what you have written recently compiles cleanly while it is still fresh in your mind.
b) It ensures that all changed files are saved. You can never save too often! "Nice computers don't go down" perhaps - but all the ones I've used have!

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

"You can never save too often!" -- I agree completely. When I first picked up on C++ I had a really old Windows 98 SE system. I received crashes quite often due to low memory, CPU, etc. At that time I typically only saved when I got ready to test new code I had added. When it would crash I would lose so much work.

So I have made a frequent habit of hitting Ctrl+S. Even if I add a previously forgotten punctuation mark in a comment, I usually go straight to Ctrl+S. Laugh | :laugh:

Thanks everyone for your responses. I don't feel so odd about it now. Poke tongue | ;-P

Don't let a PC lull you into a false sense of security.

"It hasn't crashed for ages! just means it's waiting for the most inopportune moment to do the nasty on you.

Save often.

Copy files from project to somewhere else if you don't use source control.
If you go for source control look for one that works rather than SourceSafe.
