Teemu "Joteke" Keiski has helped me solve a very trivial task. I had the simple request of accessing a GridView row data by checking a checkbox within that row. Based on the row data, I'd perform a particular task.
My GridView had a few bound columns with a few template columns. One of the template columns contained a checkbox. When the checkbox was clicked, I wanted to run the Checked event and pull information from the row that it was clicked. So, using the Checked event, I can then take that information and based on that information, I can perform a task. The example I have provided below does just that. It is a simple example where the first field in the GridView is a username from the Membership.GetUsers collection. The second and third fields are two roles that the user may or may not be part of. I want the administrator to click the checkbox to add or remove the user from a particular role. Here's the example:
Sub ToggleUserAndRole(ByVal s as Object, ByVal e as EventArgs)
'Convert Object to CheckBox
Dim MyCheckBox as CheckBox = CType(s, CheckBox)
'Convert NamingContainer to GridViewRow
Dim MyRow as GridViewRow = CType(MyCheckBox.NamingContainer, GridViewRow)
'Obtain Current Cell and CellIndex
Dim CurrentCell as TableCell = CType(MyCheckBox.Parent, TableCell)
Dim CellIndex as Integer = MyRow.Cells.GetCellIndex(CurrentCell)
'Obtain Username from first column
Dim Username as String = MyRow.Cells(0).Text
'Obtain "Role" Checked
Dim Role as String
If CellIndex = 1 then
Role = "Administrator"
Else
Role = "Member"
End If
'Add or Remove User to Role
If MyCheckBox.Checked then
Roles.AddUserToRole(Username, Role)
Else
Roles.RemoveUserFromRole(Username, Role)
End If
End Sub
