SUMMARY
This article describes how to programmatically highlight a specific row in the DataGrid control (6.0).

The same procedure can be applied in Visual Basic 5.0 using the DBGrid Control 5.0.



MORE INFORMATION
In order to highlight a specific row in the DataGrid you need to specify the bookmark of the target record within the recordset of your data source. You need to add this bookmark to the collection of bookmarks.

Each bookmark previously appended to the collection shows in the range of selected rows on your DataGrid control. You need to explicitly remove these rows from the collection before appending the bookmark for the record you wish to highlight.

The following Visual Basic 6.0 sample code demonstrates the process of searching for a record and then highlighting the hit within your grid:  Start a new Standard EXE project in Visual Basic. Form1 is created by default. Select Components on the Project menu. Select "Microsoft DataGrid Control 6.0 (OLE DB)." Select Project References and add "Microsoft ActiveX Data Objects 2.x Library." Add a CommandButton to your form; the default is Command1. Add a DataGrid control to your form; the default is DataGrid1.  Place the following code in the General Declaration section of Form1: Option Explicit

Dim cn As New ADODB.Connection Dim rs As New ADODB.Recordset Dim cmd As New ADODB.Command Dim i As Integer Dim FindLastName As String

Private Sub Command1_Click

' Remove previously saved bookmark from collection If (DataGrid1.SelBookmarks.Count <> 0) Then DataGrid1.SelBookmarks.Remove 0 End If

' Prompt user for desired author's last name FindLastName = InputBox("Please enter the author's last name you                                 want to search for", "Find")

rs.Find "au_lname = '" & FindLastName & "'",, , 1

' Append your bookmark to the collection of selected rows DataGrid1.SelBookmarks.Add rs.Bookmark

End Sub

Private Sub Form_Load

' Open your ADO connection where "Pubs" is an ODBC DSN that ' points to pubs database in SQL Server cn.Open "Pubs"

' Create your command to query for all records in Authors table With cmd .ActiveConnection = cn           .CommandText = "select * from authors" End With

' Open your recordset With rs           ' Set rs properties .CursorType = adOpenKeyset .LockType = adLockOptimistic

' Call open using active command .Open cmd End With

' Populate the DataGrid providing rs as the data source Set DataGrid1.DataSource = rs

End Sub  Press the F5 key to run the application. Click the CommandButton and enter an Author's last name. Note it moves the cursor to the Author selected and highlights the entire row.
