If you are using the class DataGridTextBoxColumn to create the columns of your datagrid then you can access the TextBox that receives the events from the DataGridTextBoxColumn to start editing text. You probably need to add a handler for the VisibleChanged event of the TextBox and if the state just became visible then send a escape keystroke and select the row instead, and finally, you can popup your form. Note that you can set both, the TextBox and the DataColumn to Readonly to prevent changes.
Hope that helps.

I have set the dataGrid.ReadOnly = True and this is preventing the values in the cells from being changed. However,is there also a setting to prevent the cell from going into edit mode when the cell is clicked?

I am using textwriter to create a text document and writing information to it. I want to know if there is a way to format the text that I concatanate into the text that I send to the text document.
for instance: dr.writeline("Order Number" + (new ListItem(pr["ord_num"].ToString()));
I want to know if there is a way to make the text "Order Number" Bold so that it will stand out as a column.

|
|
That depends on what you use to view the text. There is no formatting of that kind for plain text.

I am using a TextWriter to create a text document that I am passing the information into. It would be nice to create a word document or excel document. I have not been able to find any information on creating those types of documents.
|

|

A simple TextWriter won't do what you want.
Have a look here. It's a library which should help you to generate a word document.
Another possibility would be to create a RTF document. Use the search function here on CodeProject. You should find at least one article about it.
|

|
|
If you write a word document, or a rich text document, or even a HTML document, you can make the text bold. HTML is probably easiest. A .txt file can't do that, it's plain text.

A friend of mine point out to me to do it as an HTML, that is working much better than the text document.
Thanks to all

hi there,
i´m figuring out what´s the best way to check network services with c#?
i want to check if RDP and ICA Services are up on my servers. i tried
to just open a TcpClient and if it throws an exception on connect() i
guessed it´s unavailable. But thos didn´t work for me. it always throwed
the exception though the service was online. increasing timeout-values
didn´t work either.
i also tried connecting via System.Net.Socket but i gut the same results.
any ideas how i can check network services with c#?
best regards from .at

i am a newbie to c# and have a problem to which i have found no solution. in my search for controls that look like the ones in win xp and office 2003 i came across this website http://www.steepvalley.net/ that provides such controls for free. i immidiately downloaded the setup files to use in vs .net
however i am unable to use the controls. i tried to add com components to the toolbox however it gives an error that the dll is not a com component and thus cannot be added to the toolbox. these controls are really cool (from the pictures provided) and i would really like to use them...but sadly have no idea how. any help would be much appreciated.

It seems those controls are not COM controls then, they are .NET controls. Try adding them to the toolbox manually by browsing for it.
Also note that in .NET framework version 2.0, Windows Forms has a complete set of menus and toolstrips that come with customizable looks, including the Office 2003 look.

You need not do anything to fire. When you press Enter key it will automatically get fired.

I have an MS Access table that I'm accessing from C# (via MSDE 2000). The primary key in the table is just an int column with identity set to "yes" and step set to '1'. So whenever I add a record Access automatically gives it a new primary key. Yay.
That works fine, but what I'd really like is to be able to retrieve the key that Access generates at the time that I insert the new record.
So right now my C# program just figures out the values for the non-primary keys and then sends an INSERT INTO command. Is there anyway to automatically retrieve the new ID that Access generates?
The only idea that I have so far is to create an additional column in the table called "isNew" or something. When the user submits the new record, the SQL statement could set the "isNew" column for that record to the user name. Then I could immediately send a SELECT to retrieve the ID WHERE isNew = 'user name'. Of course, then I'd also have to send yet another UPDATE to SET isNew = ''. So it's kind of a cumbersome solution, but at least it will work.
Anyone have anything better?

Get the most recently created id by running the query "select @@identidy" with the same database connection.

Thanks! I think that will work well. My only concern is that if two users simultaneously add records to the table, there could be trouble. But if I run the select query within a line or two of running the insert into query the chances of this happening are very low, right?
I would still like to have a full-proof method for future reference though. While I will only have a handful of users on this database at the same time, the program might conceivably need to be scaled up to over a 1,000 users.
Any idea what might work in that case?
