If the information is same for all user load the data in the Cache, so it will not hit database every time to retreive user information and data population will be fast.

Well you could load the data...wait..."pls pls i am urgent regarding this". Sorry, don't respond to rude requests like this. It may be urgent to you but not the rest of us.

Are you going to show 180 offices in a single page or will you use pagination? Surely if you are going to show 180 offices and its related information which comes from the database, your page load will be affected as far as the performance is concerned.

Hi!
I have 2 tables in MS SQL database - one is just ID and Description of an Client Type, the other is ID, name, address and ClientType_ID. I have a GridView which is binded with SqlDataSource. The select statement returns all. I have made on the place of the ClientType_ID to be shown a DropDown List with the Description of the Client Type, not the ID, so the user can choose from it. I've enable on my SqlDataSource update, insert & delete statements. I was hoping when I edit the GridView and change the value in the DropDown List that it will update the table. But not only that didn't happend, but I have this error:
Incorrect syntax near 'nvarchar'.
Is anyone has any suggestions how to update the ClientType_ID in the table with the names of the clients, but choosing from the Description, not the ID of the ClientType?
What's with this error?
10x in advance!
This is the gridView and the sqlDataSource

Hi Devs,
I have couple of button in a form and sometimes when i click on it, instead of jumping to button1_click it jumps to one of the dropdownlist1_SelectedIndexChanged and generates error and application fails. And this doesn't happen every time but it is happening randomly.
Any idea what's going wrong here ??
Thank You
Andyyy

Are you sure the action occuring behind the button click event isn't, under specific circumstances, changing the selected index in the drop down list, (i.e., maybe it's filtering or repopulating the items in the the drop down list), and thus firing the index changed event entirely appropriately as the selected index has actually changed?

considering hosting website on vmware? advantage is i can snapshots and if suspect security breach i can always revert back to a prev snapshot (or i can even do this say weekly)?
downside is of course it's slow[er]
anyone with experience in this?
dev

Its fine for testing purpose, but i will recommended not to use in production environment. Because for speed of server. I don't know the configuration of your server. If backup is the only reason to use VMware, you can use other tools to backup. . This is my personal opinion.
|
|
|
|

but being able to restore snapshot say weekly (or even daily) really gives peace of mind any security breach won't linger too long...

Well, it depends on how you configure the VM.
In a ideal case, the pefromance should ot differ from a physical server.

there's got to be difference, just how much and how much is acceptable...
you done this in a prod env before? I am contemplating doing this for a low-medium traffic shopping site.

This is an insane idea. You can install all sorts of backup software on your server that does what VMWare does with snapshots.

no not just disk backup - what if your box has been hacked and you don't know what it is? If I can say even restore snapshot on say monthly basis - I can have the peace of mind my system is *clean*.
I'm considering this for a site with low-medium traffic - if speed is concern then I can buy faster hardware to compensate.

You can backup your entire system with tools like Ghost, on a regular basis, and you can restore the hard drive to that state, just like a snapshot.

Hi all,
I developed workflow application in .NET with framework 3.5,
I Put 2 interactivity in workflow as A1 and A2,

Its very difficult to say the reason with out your code. You are passing any parameter named workflowType which is passed as a null. So verify your code.
BTW : This is not related with ASP.NET, you need to post it over here WPF/WCF/WWF Forums

WTF?
Exactly what exception will return ds throw? Surely the try block should go around everything, not just the last line.
You are not doing anything in the catch block other than rethrowing the exception. Remove the catch block it is not required.
Your connection is stored elsewhere. .NET does connection pooling, don't keep connection objects around, create a new one each time.

Hi,
Have you tried to debug it by setting breakpoints and stepping into the execution lines? Debug and you will definitely find the issue.
