Now I am going through the rows of the gridview manually and need to get the values. You can see I have tried different ways. How can I do this from clicking a button to get the values instead of any other event? I only get True or False returned instead of the text in the dropdownlist controls.
Code:
For X = 0 To gvFields.Rows.Count - 1
Dim chkBox As CheckBox = CType(gvFields.Rows(X).Cells(0).Controls(1), CheckBox)
If chkBox.Checked = True Then
Dim ColumnName2 As String = Trim(gvFields.Rows(X).Cells(1).Text)
I am populating a DropDownList from a text file (class requirement).
The file is read in the Page_Load method and the DropDownList is populated then.
When I press the Submit button, throughout the process of the code it is supposed to get the SelectedIndex and use it to grab a value out of a List(Of ).
The thing is, nothing is ever passed through. I even setup an alert box and it passes right over the alert box and never even triggers it, but gives me an Index out of range error when it moves to the line right after the Alert.
