Hi Muskan...
i think u can use d update query to edit the database...
u have to give d code inside d update button click event...
for executing update query by code u can have SqlCommand class.
and executenonquery () method of it.

eg:
SqlCommand sqlcmd = new SqlCommand(sqlQ uery, connection variale);
sqlcmd.ExecuteN onQuery();
open and close d connection for d operation...
while writing d sqlQuery. do it with some condition like

"update table set cols...... where colname=textbox value"

hope this helps...
thanx,
sand..

thanks for reply......

I know this method
but I want to know some other method for update the records

I mean to say........
suppose there 10 textboxes on the form
and I want to change value of more than 5 textboxes then we have to specify all textboxes value in SET clause .

I think this is not the good way to update.This method is fine when only 1 or 2 textboxes on the form

So can u give some other method to update.

thanks.

Hi Muskan,
sorry 4 being late...
did u mean the prob that even if u edit only one txtbox then also u will update the whole cols???
can u try it using TextBox1_TextCh anged() event?
means within each textbox's change event u will append the query to d string...
ie. first u declare a string to store d string - "update table set "
then within each event append the corresponding textbox value as columns...
here d prob is that it may not look good if there r many no. of textboxes...
hope this helps...
thanx,
