IsReadOnly

[Avi Avni]

Hello

I need to give the numeric up down IsReadOnly property, and the user can't input data.

IsEditableProperty =False  the user can insert data in the keys up/down arrows,page up/down keys.

How to implement this scenario?

Best regards

Ehud.

Hi Ehud,

Thank you for contacting us.

You can use instead the IsEnabled property set to False.

Hope this will help. If you need further assistance please let us know.

Hello Konstantina

This not good for me, I want to copy/past from the numeric up down.

Do you have another idea?

Best Regards

Hello Ehud,

You can try setting the SmallChange and LargeChange properties to 0. In that way when you click the arrows the value will increase/decrease with 0, so it will remain the same.

<telerik:RadNumericUpDown SmallChange="0" LargeChange="0" IsEditable="False" />

Hope this will help. Please let us know if you have any other questions.

Sincerely yours,

Hello,

The proposed solution is not working. I tried several approaches to switch this control into a readonly version without success. So far I have to put an invisible textbox and switch visibility at demand. Boring... Why don't you implement an IsReadOnly property, as most controls do ? Telerik make me lose time with this simple requirement !

This was posted in 2010 and there is still no ReadOnly property in this control. IsEditable does still not work in Q3/2013. Setting IsEditable to false you can still change RadNumericUpDown's value.

Like Arnaud I also don't understand why we have to search the forums to find a solution for such a simple scenario. Nearly every other control has a ReadOnly property so this such have it too.

Hi Johannes,

Thanks for your feedback. However I'm afraid I cannot commit any time frame for this feature request. What I can suggest you meanwhile would be to manually disable the buttons in the Loaded event handler (for example) when the control is not editable:

private void Num_Loaded(object sender, RoutedEventArgs e)
{
    var numeric = sender as RadNumericUpDown;
    if (!numeric.IsEditable)
    {
        (numeric.Template.FindName("increase", numeric) as RepeatButton).IsEnabled = false;
        (numeric.Template.FindName("decrease", numeric) as RepeatButton).IsEnabled = false;
    }
}

Hope this helps.
