Hi,

I've 2 radnumerictextbox ( A & B )  in a row in grid.
Each one have dictinct textchanged event functions (FunctionA & FunctionB)

When i modify B, FunctionB is fired. FunctionB modify the value of A.
If i modify again B, functionA is fired instead of FunctionB.

Is there a way to cancel this event after modification in code behind ?

Thanks

OPL

Hello,


If you do not want to fire "OnTextChanged" event, then set the AutoPostBack property of RadNumericTextBox to "false".

Hi Shinu,

I need to keep "ontextchanged" and autopostback to true.

I try this :

Function A_textChanged(ByVal sender As Object, ByVal e As EventArgs)
    RemoveHandler B.TextChanged, AddressOf B_TextChanged
    .....
    B.value = "test"
    ......
    AddHandler B.TextChanged, AddressOf B_TextChanged
End Function

but it don't work.

Thks for help.

Hello OPL,

Could you please try to change the RadNumericTextBox controls with standard asp TextBox controls and verify whether the same behavior is expected? Let me know about what your findings are.

Kind regards,
Martin

Hi Martin,

I think my trouble happen when i put a data which have a different format than describe for the radnumerictextbox.
For example :

radnumerictextbox RTBA with option NumberFormat-DecimalDigits="2"
RTBA.value = "5.897867"
if i focus on RTBA and leave it without changing value, the "ontextchanged" is anyway fired.

I modifie in code behind for format data instead of radnumerictextbox and it's ok

I still have trouble when i press enter on my textbox after chage value. The event "ontextchanged" is fired two times

Thanks for helping me, it's quite hurry

Hello OPL,

With regard to:

"For example :

radnumerictextbox RTBA with option NumberFormat-DecimalDigits="2"
RTBA.value = "5.897867"
if i focus on RTBA and leave it without changing value, the "ontextchanged" is anyway fired.
"


I am afraid that this is a limitation of the control that is observed on initial load only. The only available workaround currently is to set NumberFormat-KeepNotRoundedValue="true" of your RadNuemricTextBox.

As to:

"I still have trouble when i press enter on my textbox after chage value. The event "ontextchanged" is fired two times"

Indeed the reported behavior is observed for RadNumericTextBox even when the controls are outside of a grid. The strange thing is that although it looks like the event is fired twice, the value of the text box is changed only once. Anyway, I have forwarded your report to our developers for further investigation. Unfortunately, I can not provide you with exact estimate about when the problem will/can be fixed. However, you can follow the status of the issue in our public issue tracking system.

Martin

Damn annoying.

Hello VaticNZ,

The first problem (TextChanged fired on Focus-Blur without changing the value) is resolved in the Q2 2012 release (expected in the beginning of June). To verify that the control works as expected in your scenario, you can try the BETA version of the Q2 release. It should be available for download later today or tomorrow.

The second problem is already resolved.

I hope this helps.

Kind regards,
Martin
