Tables - Cell Click

[jjspike]

Hello,

I am new to the realm of PDA development and have not coded for close to 15 years. I really enjoy using basic4android and find it very "gentle" on the system! I have been working on my first app and ran into an issue with tables and the "click" events.
I populated my table with data from a SQL server (thanks for the tutorial) and would like to display text when a cell or header is clicked. I created a handler to handle this event in this manner:

Sub Globals
Dim btnButton1 As Button
Dim edtText1 As EditText
Dim lblLabel1 As Label
Dim tblTable As Table

End Sub

.
.
.


Sub tblTable_CellClick
ToastMessageShow("Cell click", False)
End Sub

Sub tabTable_HeaderClick
ToastMessageShow("Header click", False)
End Sub

When I click on any cell or header, the handler code is never called. I created a button handler as such and it works fine:

Sub btnButton1_Click
If edtText1.Text <> "" Then
lblLabel1.Text = edtText1.Text
Else
lblLabel1.Text = "!! ENTER TEXT !!"
ToastMessageShow("Enter text to copy", False)
End If


End Sub

Can anyone assist with this?

Cheers!

In your routines you are missing the parameters:

Sub tblTable_CellClick(Col As Int, Row As Int)
      ToastMessageShow("Cell click Col = " & Col & " Row = " & Row , False)
End Sub

and

Sub tblTable_HeaderClick(Col As Int)
       ToastMessageShow("Header click Col = " " Col, False)
End Sub

Do you have two tables ?
You use 'tblTable' for CellClick and 'tabTable' for HeaderClick ?
Best regards.

Thank you so much for your reply Klaus! I have only one table however I chaged the name a number of times and entered a typo. I have added the parameters and still no luck. In fact, I copied your code and directly replaced what I had. I did notice that the first time when I keyed in the parameters, the help did not appear to indicate that I had to enter two integer parameters. It is almost as if the "Table" module has not registered. Any further ideas? I must have messed up something really bad or made a silly error as this does not seem difficult.

Thanks again!!

Post your whole project as a zip file (IDE menu Files / Export As Zip).
So we could see what you have done and how.

Best regards.

Thanks again Klaus. I have attached the sample code for review.

Cheers!!

You must replace this line
tblTable.Initialize(Me, "Users", 3)

by this line
tblTable.Initialize(Me, "tblTable", 3)

You set Users as the EventName but you call the routines tblTable_Click and tblTable_HeaderClick ?

You could also leave tblTable.Initialize(Me, "Users", 3) as it is
and rename the event routines Users_Click and Users_HeaderClick

Best regards.

Thank you Klaus. Earlier on as I was testing various features and totally overlooked the fact that I had made this change. I was so confident that I did not do anything dumb that I did not look at that area of the code. Again, I have not coded for 15 years and my brain is very rusty! :sign0013:

I apologize for this and thank you very much for your fantastic support!! You are a true star!
