hi all,

In ASP.Net , i'm using a dataset. I want to find whether it has any values
or not. How to do that?

Thanks in advance.

Hi

here are some example of it. lets say your dataset name is "ds" then,

ds.Tables.Count returns number of tables in dataset. ds.Tables[0].Rows.Count
returns number of rows in first tables. ds.Tables[0].Rows[0][0] return value
of first table's first row's first column.

Hi Gomathi

"ds" is the DATASET object

U can use

int tot_rec
tot_rec=0

if(ds.Tables.count>0)
tot_rec= ds.Table[0].Rows.Count
end if

U can also check if a column has values with

if (ds.Tables[0].Rows[0][0] == DBNull.Value)

That checks if the first column of table[0] first row has a value
