Insert a Meta Refresh tag, <meta http-equiv="refresh" content="5"> which would automatically reload the page every 5 seconds.

- Add a server-side hidden field to your page.
- If you set something (either true or false) to the visible of div, you should also set that value to this server-side hidden field.
- then, you check this hidden field from server-side whether it is true or not before binding to the datagrid..

Hope it helps..

There is no direct method available it seems. You could use a flag column and change the value when a user starts editing record. Before editing check this flag value.

If you use this method, make sure you have the ability to reset the column on error. (try /catch / finally). If your code crashes after setting this column for edit, and before resetting it, nobody else will be able to edit.

In C++ I would generally use RAII for something like this, but C# destructors are non deterministic, so RAII has to be implemented via 'using'.

i create an asp.net website using membership and ..
it works fine on local but when i deploy it to internet this error occures:
--------------------------
An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the
fact that under the default settings SQL Server does not allow remote
connections. (provider: SQL Network Interfaces, error: 26 - Error
Locating Server/Instance Specified)
---------------------------
My web config contains this:

<connectionStrings>

<remove name="LocalSqlServer"/>

<add name="LocalSqlServer" connectionString="Data Source=.
\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|
aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />
</connectionStrings>

I think you can't probably use "." in hosting. You should ask your hosting service about how to connect to your SQL database. We can't say about that for sure since the connectionstring might differ from host to host...

You have to add attributes to all the controls. Assume you have a textbox with name Text1, then you could add Text1.Attributes.Add("onkeypress","function()"). You should change the event name and calling methods according to VBScript syntax.

Why ? Better use javascript. VBScript is supported only in Internet Explorer.

felicitous place would be Page_Load().

Priya_2007 wrote:

What is valuetype ? I am not well-known in VBScript. In javascript it can be written like

Text1.Attributes.Add("OnKeyPress","Function(valuetype,event);");

event contains the keyCode which is used to find what is the key pressed.
