null values to column in the datagrid

[shawlin]

Hello,

I have a problem Here.
I have a button fetch all, when i press the button
i will frame a select statement like
sstr = ""
sstr = sstr + select menu_id,"
sstr = sstr + parent_id,"
sstr = sstr + menutext,"
sstr = sstr + iconfile,"
sstr = sstr + appid,"
sstr = sstr + from menurelations"

orada = new oracleclient.oracleadapter

orda.fill(ds,"menurelations")

datagrid_menulist(ds,"menurelations")

the value has been populated in the grid.
Here i will have the problem.
If there is a null value in the say in iconfile or
some of the fields.How to pass empty values
to the grid.when i say nvl(iconfile,' ') iconfile this
will solve my problem.But if i have more than 20
or 30 fields in the table will have null values suppose.
Generally how do i handle this.


hope the question is clear.


Thanks and regards
shawlin

You may pass DBNull.Value instead of any null value to the database. In case of strings "" will pass a string that is empty, still its not a null value that means nothing at all.
