Hi,

I am trying to filter data table _title on its PK by passing titleid through a function. But it does not work.

Private Sub Fetchrecord(titleid As String)
       
            '_title.Select("TitleID = " + titleid)
            _title.DefaultView.RowFilter = "TitleID= '" + titleid.ToString() + "'"
                 
    End Sub
I tried both the above lines Still no luck

PS: I have tried all links available on google but no luck

What is your goal for filtering the datatable? Do you need to bind the result to control(s)? Do you need to find values in that same row?

The commented out line will return an array of datarows.
The second modifies the defaultview of the table, but not the table itself.

Try:
Dim dv as DataView = _title.DefaultView
dv.RowFilter = "<filter>"

Then use dv.

as started by shaun:

Dim dv as DataView = _title.DefaultView
dv.RowFilter =  "TitleID= '" + titleid.ToString() + "'"

What does it mean to be "Always On"?

Dim dv as DataView = _title.DefaultView
dv.RowFilter = "<filter>"

This filters the grid itself which has binding ! I just need to find row without affecting my databinding

just bind your grid to the dataview instead of the datable!

Going back to my original question, once you have the row with that PK, what are you going to do with it?

There are a number of ways to get that row in various object types. Understanding what you wish to do with the datarow will help us find an answer for you that works.

your grid is currently bound to _title? make the dataview a member with a scope of the form and bind your grid to this new dataview variable
