how to loop through a winforms datagrid to get all selected(checke

[Guest]

Any pointers as to how to loop through a winforms datagrid to get all the
selected(checked) columns?

Are you asking how to determine which rows have a certain column value that
is checked in the DataGrid? If so then I assume that the column is bound to
boolean column in the underlying DataTable. So just loop through this
column, in the DataTable, looking for "True" fields.

thanks in advance

Here is some code to get you started.

' This code assumes that you have bound a DataTable to the DataSource of a
DataGrid.
' This code also assumes that there is a column named "Bool" that is of type
Boolean.
' This code ensures that in a tri-state check scenario the "Indeterminate"
state is ignored.
Dim dt As DataTable = DirectCast(Me.DataGrid1.DataSource, DataTable)
For Each row As DataRow In dt.Rows
Dim obj As Object = row("Bool")
If (TypeOf obj Is Boolean) Then
If (DirectCast(obj, Boolean) = True) Then
' Get ID here.
' Example, Dim id As String = DirectCast(row("GUID"), String)
End If
End If
Next
