So can we create a table on the fly which contains the the messages table and an additional column, comment_count. I mean what can be done in the Dataset so we can inherit the messages table and add an comment count column which's value evaluated by another SQL statement.

That's also what I mean, you can add a new column to the current messages table and manually add the values for this column from executing another statement or you can manipulate the values from the second table in the dataset. In addition, you might also consider creating view or store procedure to populate the messages table with the comment count in one go.

Hello,

I am working on a form to edit some users information. As I have it right now, when the administrator is going to change a user's info, they first search the user to make sure it exists. The information appears on screen - or gives an error if the user doesn't exit - and the admin now presses the "Modify" button.

Here's my question: Is there a simple way that I could change the tags in which the information is shown to a drop down list? I know I can do it in the code behind using a string that contains the HTML code and then output it with Response.Write; but then my drop down list would lose all it's ASP.Net functionality.

I figure I could do it on the aspx file if I use a lot of conditionals to go around the HTML/ASP.Net code that I don't want; but I don't find this a clean way to do it.

Thanks in advance!

You can simply add two controls in the web page and depending on the context you can set the Visible property of the control accordingly to show/hide the control. Another option is that you can dynamically add the control (not the html markup) to the web page at runtime, but you should be aware of a couple of things when working with dynamic controls.

Hello,

Thanks for your reply! Even though I had thought of what you speak, it didn't sound "clean" to me. Yet, I recently found an article explaining exactly what I wanted to do. You can find them here:

SqlConnection con = new SqlConnection(connstring);
SqlCommand cmd = new SqlCommand("SELECT * FROM customers", con);
SqlDataAdapter da = new SqlDataAdapter();
DataSet ds = new DataSet();
da.SelectCommand = cmd;
da.Fill(ds);

DataTable dt = ds.Tables[0];

return dt;

what is the purpose of using selectcommand(da.SelectCommand = cmd)

Hi,
I have a web page that displays a line graph. The control I was using under .Net 1.1 was WebChart from www.carlosag. When I migrated the site to .Net 2.0 the chart started to behave strangely in that all text was displayed as symbols. I thought maybe the chart was in some way not compatible so I downloaded ZedGraph and have discovered that I get the same behaviour. So it's obviously not a control specific problem. I reloaded the .Net Framework 2.0 last night but that didn't help. I'm developing under Windows 2k SP4 using Visual Web Developer Express. Any ideas? I'm getting desperate

thanks
mike

Hi
I have to populate some datas from sql server database and display it directly in a CSV Format or CSV file. When i run the project it should provide me an option to whether open or save or cancel the file. when i click open it should be opened and be viewed in a excel sheet in CSV format and when i click save it should ask the destination folder and should be saved there in CSV format and when i click cancel it should be cancelled and the application should be closed. pls note that all these actions should happen in the same browser and should not be redirected to anyother page. Can anybody give me the detailed description and code in Asp.Net using C# .It's very Urgent.

Regards
Vijay.

Well, you should know that "very (very) urgent" act as a filter and many simply do not want to help when those words are present because a) it is homework or b) the poster did nothing to investigate the topic himself first.

how to display a message like 'please wait while page loads' when an aspx page takes long time to load....so as to make sure that the users don't panic and run away before it finishes. thanks in advance.

The easiest way to accomplish this is to use the SEARCH method.

There are plenty of examples of progress controls here and elsewhere.
