Thanks Mike

Hi Manoj,

The UltraCombo itself doesn't have any built-in delay. But it seems to me that you could implement one.

In ValueChanged, instead of going out the database and retrieving the data, instead just start a timer. If the timer is already running, you restart it.

Then in the Timer_Tick event, you go out and build the list from the data source and stop the timer. That way, if the user types a character, they are given a short time in which to type a second character before the data retrieval is done.

AppStylist uses a similar method when you change a property so that it doesn't re-style everything while you are in the middle of typing in a color, for example.

Hi Mike..

Thanks a lot...I would give it  a try as you have explained..

In a ultracombo when ever i change the text, in the ultracombo textbox, the event  text changed gets triggered...In our application based on the character that is keyed in the ultracombo textbox we hit the database and filter the records based on the 'text' that is entered in the ultracombo

for instance...

when i key in input APPLE in ultracombo text box....The text changed event gets triggered in the following pattern A,AP,APP,APPL,APPLE...correct

Is there any way where we can set some delay on the ultracombo so that i accept some set of input text from the  ultracombo and then at once trigger the text change event ..

for instance

when i key in APPLE...i want the text change event to wait until that delay and accept the text with in that delay say may be APP and then trigger the text change with the input APP and do then filter the reocrds...

Please let me know if this make sense

Thanks

Manoj

Hi Manoj,

No, UltraCombo does not support editing in the dropdown portion.

If you want to try to implement the highlighting yourself, then you could do it the way we cannot. What you would do is hide your real DisplayMember column in the dropdown, and then add an unbound column of type String and set it's Style to FormattedText.

Then you could set the Value on the cells in the unbound column to a string which uses the FormattedText capabilities to highlight the text you want.

Hi Mike,

Thank for the reply..

Can you please tell me if is it possible to enforce the column(s) in ultracombo to edit mode at runtime

I am asking this because there are properties in ultragridcell like seltext, sellen, selstart, selectedAppearance, so i was just thinking if i could make use of these properties and achieve the requirement..

Thanks

Manoj
