Hi Senthil,
Name property will not work in this case. It should be the Text property. Name will be used as identifier and will not be displayed on button while Text is actually displayed on button. Try to change the name to "&Click". It will show invalid property dialog box. With Text property it will work smooth.

You can use an attribute to turn off this error. Or, you can use a worker thread which sends messages back to the main thread, whch can then update the UI.

Create a new thread while making any calls to server. Let that thread handle it. If u r using .NET 2.0, use form.InvokeRequired().

Hello,
In one hand I do agree with you, because there are a lot of ironic answers in this forum.

Where is the data being loaded from? Why are you loading some much? What do you mean, "going thro each and every record"? Lots of unanswered questions here.

Do you mean the table in the database or DataTable object?

You should prepare your data ( do the loop ) then process it to the DB all at once, or at least in batches. One DB call per record will indeed take forever.

you can use paging to minimize the mount of data you are retrieving , or if you are searching then maybe you can do that process on the SQL Server side or whatever you are using...

I had to update/insert a couple of 1000's records once. What I did was concatenate the inserts (delimit with ";") and fire it up to the database at once...
eg.
"INSERT INTO YOURTABLE (COLNAMES) VALUES (COLVALUES);INSERT INTO YOURTABLE (COLNAMES) VALUES (COLVALUES);...;INSERT INTO YOURTABLE (COLNAMES) VALUES (COLVALUES);"
In your case don't do it at once, but in blocks.
Hope this helps.
