Using Arrow buttons instead of Tab to toggle between Textboxes

[adarshyam]

Hi..
I wanna use down arrow and up arrow to move between TextBoxes(that are Dynamically created) instead of the default Tab key.. Please help me if u ve any idea.. Thanks

You will have to handle the KeyDown event for each textbox, and check to see if the keys are one of the arrow keys, and then .Focus() on the appropriate textbox.

Public Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
 
If IsPostBack Then

MsgBox(
"Enter the Number of Periods")
 
End If
 

'To create the dynamic text box and add the controls to panel, save them in session state

For i As Integer = 0 To numofper - 1
 
TxtDyn1(i) =New TextBox
 
TxtDyn1(i).EnableViewState =True
 
Panel1.Controls.Add(TxtDyn1(i))
 
textdynamic1.Add(textdynamic1)
 
Next

The [TAB] key uses an index on the form. You can set the order of movement by setting the Tab Index.

For your want you will have to write a method that scans through all of the controls on your form, get the .Location of each control, then determine which control is "down" from the control that currently has focus.

You'll have to decide which is more important: If a control exists that is lower in location, but far to the left - of a different control that is maybe 2 pixels lower, but not as many pixels away horizontally.
