always a transaction ends with commit or rollback.
COMMIT means transaction is completed.
ROLLBACK --reverses the current transaction
If any tranaction breaks down in the middle then the transaction will rollback automatically
use
BEGIN TRANSACTION
COMMIT TRANSACTION
ROLLBACK TRANSACTION
in database procedures. so that you don't have to worry about power cut off

That's correct. But in this case if the use closes browser before procedure complets execution, I don't think that it will rollback transaction. What do you say ?

I agree to your point. Save button click will save the data and browser close button click will close the browser window. in this case there is no way to stop the procedure execution or rollback the transaction.

The idea could be to use the transaction from the page itself for eg:
SqlCommand cmd;
try
{
SqlConnection con = new SqlConnection();
con.Open();
con.BeginTransaction();
cmd = new SqlCommand("Update bla bla bla");
cmd.ExecuteNonQuery();
cmd.Transaction.Commit();
}
catch (Exception excp)
{
cmd.Transaction.Rollback();
}
In theory this should work. Please let me know if it helps.
Thank you

Hi,
On clicking Datagrid Press "F4" and go to properties and click the right most icon on top of the properties window. Go to Format tab and click columns and specify the width.
This will sort out the issue.

Does anyone know of a grid control that would mimic the grid control used in MS Outlook and Microsoft Live! website. Specifically, I'm looking for a control in which I can bind the data in one row of a record to "One Cell" in a grid, but in different locations. So, in the end, I would have Field 1 in the first line, field 2 in the line right below field one, field 3 in the top-right hand corner, and so on, placing the fields as I like.
to get a better idea, you could look at the Outlook grid when the Reading Pane is set to be on the right, instead of the bottom.
Thanks
RR

Why don't you just use the Gridview control with a custom Template field. You could also try a datalist as this should work as well.
As far as custom controls go I use the ComponentArt library, this will also do what you are looking for (assuming I totally understand what you are looking for)

Hello Everyone,
Can anybody let me know how to embed "Real Player" in ASP.NET web Application to run the .Rm and other audios/videos
|
|
|
|
|
WE have an ASP.NET forum, and in fact, you're going to do this, if it can be done, through HTML anyhow. There is no support in ASP.NET for real player, but if the real player supports this, it's just a case of embedding the right HTML in your page.

There's loads of ways! Mostly I use this[^] treeview, but I can imagine you don't want to buy such a control for just a directory tree. However, have you considered filling a dataset and display is using a grid? You can even generate a HTML table or something....

Hi friends
I have two DataTable with same structure one coming from DataBase and second I create dynamic.
Now I have 5 records in datatable1 and 5 records in DataTable2.
I want to Merge DatatAble2 into Datatable1
I am trying this.
DataTable1.Merge(DataTable1);
But after that I am getting only 5records instead of 10 records.
thanks in advance
Pathan

Are the primary keys between the two DataTables the same? This ispossibly why you're only seeing 5 records still.
from MSDN[^]:
When merging a new source DataTable into the target, any source rows with a DataRowState value of Unchanged, Modified, or Deleted, is matched to target rows with the same primary key values. Source rows with a DataRowState value of Added are matched to new target rows with the same primary key values as the new source rows.<br />

Hi surya,
I would be intrested to know how you abandon the session when the user closes the web browser. As far my knowledge goes the session will still be active till the timeout period is reached even though the the browser is closed.
Since the is no way IIS could determine if a browser is open or closed.
Thank you
