Update Dataset and Database

I'm  trying to update a dataset and its not working.  
The form has 4 different 'modes' that it opens in for different formatting reasons.  When the user loads the form in Edit Mode, the form loads and I open the connection and fill the data adapter then use the FindBy function to locate the record the user wants (code below):

Me.Con_DWS.Open()
      Da_Main.Fill(Ds_DWSMain1.DWS_Main)
Me.Con_DWS.Close()

Dim drDWS_Main as ds_DWSMain.DWS_MainRow
drDWS_Main = Ds_DWSMain1.DWS_Main.FindBySlip_no(me.txtSlip_no.text)

txtJob_num.text = drDWS_Main.job_no
txtSWO_num.text = drDWS_Main.swo_no
txtDate.text = drDWS_Main.job_date
txtLocation = drDWS_Main.job_site
txtContractor.text = drDWS_Main.contractor
txtdescription.text = drDWS_Main.job_desc

At this point I have the information in the textboxes based on what the user has entered in txtSlip_no.text.

The user can then edit some of the fields.  The user will then save the data and I run the following code:

Public Sub btnSave.....
Con_DWS.Open()
Dim drDWS_Main as ds_DWSMain.DWS_MainRow
drDWS_Main.job_no = txtJob_num.text
drDWS_Main.swo_no = txtSWO_num.text
drDWS_Main.job_date = txtDate.text
drDWS_Main.job_site = txtLocation
drDWS_Main.contractor = txtContractor.text
drDWS_Main.job_desc = txtdescription.text

Da_Main.Update(ds_DWSMain1.DWS_Main)
Con_DWS.Close()

Yet, the update doesn't happen.

I assume that ds_DWSMain is a DataSet, in which case, after the Da_Main.Update call, you need to have:

ds_DWSMain.AcceptChanges()

You shouldn't actually need to open your connections for datasets and dataadapters, as it should do that for you automatically. Not sure if that makes any difference, though

I think you are right.  The textboxes aren't bound to the dataset though.  If they were bound to the dataset, it would automatically update if there are changes.

Just realised - you haven't actually added the row to the dataset.

ds_DWSMain.DWS_Main.AddDWS_MainRow(drDWS_Main)

before Update / AcceptChanges commands
