Hi,
I have a combo box which I am populating dynamically using Datatables.
The combobox acts as a selection point from where a user selects a value and accordingly charts are generated..!
The column i am populating changes dynamically and is never the same.
Now I want to add another option "ALL" in the combo box after/before I populate the combobox...such that my combo box should have all the values frm table as well as an item " ALL " I tried doing it, but it shows error.
Can anyone help me out please. how should i go abt it..?
I am making a Windows Application using C#.
Cheers
Jimish

One thing you could do is to modify the SQL query so that 'ALL' is in the datatable.
I.e. " SELECT Value1 FROM Table1 UNION ALL SELECT 'ALL' "
Then the option value will be in the datatable and you can select it.

Query input must contain at least one table or query.
It shows the above error..!

Hi,
After binding your datatable / dataset to Combobox. Add below line.
cmBOX.Items.Insert(0,"ALL");
Thanks,

Items collection cannot be modified when the DataSource property is set.

Hi,
This might be the simplest thing ever. However.....
Our team have used SQL Reporting many times using a web page for the client to go to and select a report and a day from a calendar control then ping... a report opens in Excel and the client saves it on their PC.
What if I want to show the report in the space on my webpage below the calender and the 'select the report you want' dropdown menu. For the report to be inside my webpage?
Can I do this? We have only ever called ReportCommon.ExecuteExcel in our C# code behind page.
Even the report opening in it's own browser would be OK I guess but to the screen better.
Any thanks gladly received

I don't think you can add a tooltip to each individual item of the ComboBox. However, you could hook into the SelectedItemChanged event and change the tooltip of the ComboBox depending on which item is selected

Well unfortunately not even the most experienced of us 'experts' can no all the answers to all the problems, if people dont respond its generally because there is nobody available that can give a decent answer to the problem.

If you choose to post an answer to somebodies problem then do not say it cant be done if you dont know that for sure. If you do have an idea then post it as a suggestion and do not try to enforce that it is the only possible way unless you are certain it is. Even when you do offer your 'suggestion' you may still get some people who will knock it just cuz thats who they are. But if you know you have put a suggestion that works then dont worry about what others think. Atleast your putting in your own time to try help others

This site is free, people give their time freely to help. The downside is not everyone that is on the site that particular hour/day/month will have the required knowledge about your particular problem.
If you want fast guaranteed advice then you should search for a site that offers that, but you'll need to get your credit card out and pay.
I would also suggest you look at the reply I posted a few minutes ago.

Actually, I meant nothing like that. Maybe my questions are not efficient. But many say that I post wrong answers to queries posted by others.
Anyway, I'll keep on posting my queries here. No matter whatever happens. Only the site moderator can kick me off and not any Member (J_L_E_N). And from now on, even if I know the right answer, I'll never even try to reply. Coz my answers, cause fever to some person.
Happy programming,

It may be because you don't appear to be doing any research yourself, just asking CPians to do it for you.

I do research myself, but I dont recieve all those guidance that u guys get there in the West, U know where I stay? in Bangladesh. We get no good guidance here. Whatever we do, we do with our own knowledge and a little knowledge we get from books.

All I have is a few old, battered books (none on C#), internet searches/MSDN look ups and CodeProject. Apart from the unrelated old books (yours are probably more relavent than mine!), you have the same.
3 years ago (although I have been programming in one language or another for over 25 years), I decided it was time for me to learn C#. That's when my 'relationship' with CodeProject began. This year I was awarded CodeProject MVP (approx 1 in 150,000 members), my certificate hangs very proudly on my wall. No more resources than you, just determination and a moderate level of intelligence, combined with a willingness to learn and take criticism.

 I would like to thank Luc, Christian, JSOP - without them and their help and guidance it would not have been possible, and of course Chris and team for the fantastic site that is CP.
Also, I'd like to thank my agent, my Mrs, orthodontist and cat...
Seriously, those guys helped me so much early on (and continue to). IMO, the best way to become proficient at anything is to be a good student. I've read nearly every post in the C# forum that has been posted since I joined, and a great many from before. There is so much expertise that is just given freely - what a resource. Unfortunately most just read there own little threads and can't be bothered to spend the time being a true student.

Boo hoo! Poor little you!
You at least have the Internet. I only got access to the Internet 6 months ago but have been coding in .NET for more than 5 years. How do you think I learned? It sure as hell wasn't by pestering other people every 20 seconds. I read books, yes, but not many. What I did mainly is to use the help files that came with my copy of VS 2003. Now because my version was only the standard version, those help files were incomplete, you have access to the full MSDN help system via the internet.
Thank your lucky stars for what ever help the people here on CP are prepared to give you, freely, and in their own time.
Stop bleating man and start reading, or is google broken in Bangladesh?
Oh, and while I'm ranting, stop giving gibberish or totally incorrect answers to other peoples posts. Sometimes we all get it wrong, or misunderstand a question, but you seem to be making a career out of it!
How does it go, oh yes,
Happy programming,
Henry Minute
