How to move a row in a data table object to the top of the table? The data table is in a data set. The data is bound to a drop down list box.
I am maintaining some 2003 C#/asp.net code for a web application. In the application a table in a data set is usedto populate a drop down list box.(The drop down list box will display a list of names)
Before the data set table is bound to the list box control, blank characters are inserted at the topof the data set table. The purpose of this, is to display a blank line in the drop down list box, when the list box isinitially displayed. This code works fine. (See lines 1-14 below).
Now I have been asked to modify the source code so that instead of a blank line being inserted at to top of th...Creating a Web Form with a multiple data tables in Visual Web Developer 2005

If you are doing windows development, i would suggest using 'DataForm wizard' (Use Solution Explorer-->Rightclick project-->Add new Item-->New DataForm). It will guide you through steps. If you are doing web apps. Use quickstart to learn them.

We ca...Web Form holding an object with data
I am working on a web form which makes changes to any xml data. The xml data is handled in and out of the web form using a class object. Since this tool being a web form any number of users can access the form simultaneously. Suppose, if a user changes the xml data when another user is working on it, then the xml data the other user has is stale.
My question here is that I want to save the initial xml data in that particular web form so that when there is a change, I can get the new xml data and compare it with the old one and if there is a change in data I can let the users know about it....Web form filtering data from a table

does anyone know why the table object does not maintain its state between postbacks? If you build the table dynamically in your code and perform a postback, you have to redraw the table each time.
Also, how do enter blank items into a table? If you try to create a new cells with blank text, you end up with your table having lots of missing cells which looks really crap.
The table was not designed to carry state, exactly why it does not would be a design question for MS.

What is the best way of creating datasets for asp.net pages and populating web form objects. I have always created datasets within a sub routine and then populated my web form controls from that dataset. I was given some code that the pages were created in visual studio. I know the page gets its data from a stored procedure. What I can't find is code that calls that stored procedure and also populates the web form objects. Most of my asp.net development has been done on the asp.net page and not in Visual Studio. So if someone could tell me what to look for that would be great.
