Here are a couple of things that you might need to do:
+ Create an event handler for the client side even onlick of the checkbox button.
+ In the handler, you can get reference to the elements in other columns using the getElementById method, then populate the properties of the elements.
+ To inject the client side script for the check box of each row in the GridView control, you may use the RowDataBound/RowCreated events.

Dim conn As IDbConnection = GetConnection()
Try
Dim cmd As IDbCommand = conn.CreateCommand()
strSql = "USP_GetDealers"
cmd.CommandText = strSql
cmd.CommandType = CommandType.StoredProcedure
conn.Open()

Yes, that looks runnable. But you are catching any exception that might occur and totally ignoring it. When that happens, your code will crash somewhere else along the line, and you will have no clue why it did...

Hi All,
We have a web-service based application written in C# and running on IIS, pretty standard ASP.NET 2.0 stuff. We also have a problem, that occasionally the Application terminates for no apparant reason, calling Application_End on its way out.
Can anyone suggest what causes an application with several sessions open to terminate abruptly/has anyone seen this before? I don't believe this can be due to time-outs.
Thanks for any help.
Regards,
Rob Philpott.

Hi there,
Looks like your application is recycled, if this is the case, you might want to check a couple of things:
+ Does your app edit the bin folder or its subfolders and contents?
+ Does your app edit the web.config file?
+ Do you have any other application that may make changes in the file system of the application?

Hi, thanks for the response.
Nothing changes in the bin folder, nor does the web.config change. The filesystem remains untouched too I believe as most data is handled by Sql Server.
I did stuble across a setting in IIS under the application pool which automatically 'recycled' my application every 29 hours. What the purpose of this can possibly be I'm unclear - it seems to be like adding a 29 hour fuse to the app. Anyway, I've turned that off and we'll see how things go.
Thanks again for the help.
Regards,
Rob Philpott.

Okay so I added a grid view to my web page.
But, I dont see the grid object in my code behind so I can play with it.
Does anyhow know how to get the the IDE to define the control in the code behind?
Nick
1 line of code equals many bugs. So don't write any!!

I have a project I'm working on in ASP.NET but I'm having problem in the coding of my loging page.I have UserId and Password in my loging page.If the user iput his UserId and Password in the loging page on click of the OK BUTTON then, the login page should compare it with UserId and Password in the Database. if it matches then it should take u to the nextpage but if not he should Throw an Error message INVALID LOGIN. This Is just a normal User Login in ASP.NET .Thanks

Is this only a declaration of intent, or do you have a question?
Have you tried anything towards building this? Anything at all? Like database model? Made a login form? Written any code?
Who is this "u" person you are talking about all the time?  If you write proper english you will be taken more seriously.

Hi everyone,
I want to release the memory back to the server immediately or explicitly free up memory, should I set DataSets/DataViews to null after use or should I use .Dispose() method? Or both?
Thanks. I appreciate any help.

Hi there,
It's a good practice to release the resources back to the system, however if you want it immediately, then i'm afraid you cannot. To some extend, you may use the Collect method of the GC[^] class to force the garbage collection. You can read more about this in the documentation Garbage Collection [^]
