• Re: Binding a label to a data source

  You can provide a data source to a DDL because it can handle it while a Label control can't. For example, DDL can take multiple rows of data from a designated data source and retain it. On the contrary, a Label cannot intuitively display multiple rows of data and is thus not designed to handle a data source. If using a Label control within another control like GridView that can handle a data source, you can have it display data from "current" row as it iterates through the rows (probably

• Re: variable value... weird problem

  It's difficult to tell based on the code posted, but it should be relatively straight forward to debug this one. Simply place some break-points for the function and within the for-loop to see where the problem lies. Either the function is being called two times or the for-loop is iterating more than once. I believe that GridView.Rows refer to all rows, including header and footer if defined. That may be the cause of your problem.

• Re: Setting a drop down list selected value inside a edititemtemplate

  Still can't tell since the posted code lacks the data source definition portions. You may want to check out the following post (one of my response from earlier this year) regarding the usage of DDL within a GridView control. http://forums.asp.net/thread/1200447.aspx

  This warning message is to prevent a potential script injection by the incoming data. Have you tried the following suggestion included in the warning message? You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section.

• Re: Performance and Scalability in asp.NET 2.0

  I'm certainly no expert in this topic, but I do have few suggestions. First of all, I don't think you'll get a satisfactory answers to your questions on these boards. You'll be better served contacting Microsoft directly in regards to the load questions. I'm certain they get similar questions from many developers preparing for large projects, so that'll be the way to go. Having said that, I think the performance you seek is a function of server hardware. There's bound

• Re: Setting a drop down list selected value inside a edititemtemplate

  The error seems to indicate that your data control (i.e. GridView, DetailView, etc.) is not bound to any data source. You may want to post a more complete code to show exactly what you're doing since the snippet you included looks okay.

• Re: DISTINCT doesn't seem to be working

  DISTINCT returns unique rows based on all columns in the query, not just the first column (clientid) that you've specified.

• Re: Problem in Using MS visual web developer 2005 Express Edition

  First of all, 2005 Express Edition should be free, period (not 30 day trial). As for your question, not all toolbox controls are enabled all the time. It's context sensitive and only the relevant controls will be active for the project you have opened. For example, most of the Windows controls will only be active when developing Windows applications and inactive during development of web applications. If this is not what you're experiencing, then I suggest you install it again.

• Re: Touch Screen?

  Working with devices like touch-screens has very little to do with the development language. You should, in theory, get in touch with the screen maker/supplier to make sure they provide you with drivers for the development language you're working with. Once you've confirmed that, it's just a matter of reading up on the API's and testing it with your development language. Same concept applies to all non-standard PC devices.
