Selecting row from DataGrid

[tshad]

I have a dataGrid that I filled with files from my directory. I am using VS
2003 and Windows Forms.

*************** *************** *************** ***************
Dim dirInfo As DirectoryInfo = New
DirectoryInfo(" C:/ImportFile/Coreland")

' FileListTable.C olumns.Add("Ful lName", GetType(String) )
FileListTable.C olumns.Add("Fil eName", GetType(String) )
FileListTable.C olumns.Add("Len gth", GetType(Integer ))
FileListTable.C olumns.Add("Dat eModified", GetType(DateTim e))

For Each file As FileInfo In dirInfo.GetFile s("*")
Dim row As DataRow = FileListTable.N ewRow()
' row.Item("FullN ame") = file.FullName
row.Item("FileN ame") = file.Name
row.Item("Lengt h") = file.Length
row.Item("DateM odified") = file.LastAccess Time
FileListTable.R ows.Add(row)
Next

DataGrid1.DataS ource = FileListTable
*************** *************** *************

I want to allow the user to select the row and display file in a text box.
I can do this in asp.net but I can't seem to figure out how to do this as an
event so that when the row is selected it automatically goes and gets the
file and displays it.

Maybe by adding a radio button or something. But I am not sure how add that
to the DataGrid and then have it trigger an event.

At the moment I have my tableStyle set as:

*************** *************** *************** **
Dim gtStyle As New DataGridTableSt yle
gtStyle.Mapping Name = "FileListTa ble"
gtStyle.Alterna tingBackColor = Color.LightBlue

'
' Create GridColumnStyle objects for the grid columns
'
Dim colStyle1 As New DataGridTextBox Column
Dim colStyle2 As New DataGridTextBox Column
Dim colStyle3 As New DataGridTextBox Column

'
' Set column 1's caption, width and disable editing.
'
With colStyle1
.MappingName = "FileName"
.HeaderText = "File name"
.Width = 300
.Alignment = HorizontalAlign ment.Left
.TextBox.Enable d = False
End With

'
' Set column 2's caption, width and disable editing.
'
With colStyle2
.MappingName = "Length"
.HeaderText = "Length"
.Width = 100
.Alignment = HorizontalAlign ment.Left
.TextBox.Enable d = True
End With

'
' Set column 3's caption, width and disable editing.
'
With colStyle3
.MappingName = "DateModifi ed"
.HeaderText = "Date Modified"
.Width = 100
.Alignment = HorizontalAlign ment.Left
.TextBox.Enable d = True
.Format = "yyyy-MM-dd"
End With
' Add the GridColumnStyle s to the DataGrid's Column Styles collection.
'
With gtStyle.GridCol umnStyles
.Add(colStyle1)
.Add(colStyle2)
.Add(colStyle3)
End With

'
' Add the GridTableStyle to the DataGrid
'
DataGrid1.Table Styles.Add(gtSt yle)
*************** *************** *************** **

Thanks,

Im using vb.2005 express...not sure if it would be the same or if this is right but
this is what I do.

iIntegerValue = CInt(DirectCast (Me.StaffDataGr idView.CurrentR ow.DataBoundIte m, DataRowView).Ro w.Item("StaffID "))

In my case I just wanted to store the key into an integer value from the Staff Table, from
the StaffID column from the record.

But I think your looking for this:
Me.StaffDataGri dView.CurrentRo w.DataBoundItem , DataRowView).Ro w.Item("StaffID ")

Hope this helps...

im a newbie so it may not be the right way.

Tom,

I think that this sample comes the most in your direction. As written it is
for a DataGridView (a new control in version 2005), however just changing
that to DataGrid will make this workd.

There is a list of samples on this page but nothing on how to respond to a
users selection of a row.
