prevent clear button in toolbar from clearing the selected field.

I was successful in implenting this using a button in interface. But when the clear on the top in toolbar is pressed, my selections are cleared. How can i prevent this from happening.

Dear ,

means you don't want to remove the default selections ?

if it's then try to make the default selections and lock those fields.

are do you want to achieve something else?

Thanks,

Mukram.

I guess its not possible too. Even if i lock a selection and then press the clear button in toolbar or in the accesspoint toolbar, all the fields are cleared. but was curious to know if there is a way to do it.

Dear marks munich,

if you make any field lock then even if you clear from toolbar also the selection will be available.

A locked field should not be cleared by the Clear icon.

If you have a clear action on a button, have you selected the action as "Clear All" or "Unlock and Clear All"

There are many options for Selection Actions

For example i want to select the year field and then, it should not be cleared at anycase,might be with clear button on the toolbar or the clear button with actions in the user interface. but the same time I have implemented another button which unlocks all the field and clears all the fields in the interface.

The button/text object that sets the year field needs a second action to lock the year field. This will allow users to click clear without changing the year value.

You can add multiple actions to an object.

For this case, you may get what you want by setting the "Always One Selected" property.

You can find that in the Properties --> General tab of List box. And that can be enabled only if you select a value in the list and come here

Cheers,

In the desktop client, you can define, or set, the Clear state. Try this from within your application:

Clear all fields
Select a value in the field that you, ultimately, do not want to be cleared
Go up to the Clear button on the Navigation toolbar
- click on the down menu arrow
- select the Set Clear State option

I often use this functionality during desktop dev and testing. Haven't had to apply the functionality in a published app, but every reason to believe it will work there, too. If anyone knows otherwise, please inform this post.

Good luck

Ellen,

Thank you for your reply on this topic. Your suggestion ("Set Clear State" option) was a solution for me since I have to keep multi selections avaialble.

BTW, it works on published documents too.

Vladimir
