hey guys

I've a problem with the filter in the MultiColumn ComboBox:

If filtering is turned on, and I type some letters in the CB that only one row is left in the combogridview, this row is autoselected from the combobox.

Is there a way to disable that function because when you type fastly you don't get when the row is autoselected. That means you write some more letters after the autoselect.

So for example if I would like to select the row "Media":

1. I type "Me"
2. only one row is left in the combogridview and the row "Media" is selected (also in the combobox.text is now "Media")
3. I dont get that and continue with "dia"
4. So in the Combobox the Text "Mediadia" appears

Hello,

Unless I have mis-understood, I haven't been able to replicate your issue. Please could you provide a small sample showing all the settings to re-create this issue and I'll do my best to help.
thanks

Hi leowns,

I did not manage to reproduce the issue. I would kindly ask you to create a support ticket with an enclosed project, where the issue occurs. This will help us to understand your scenario and approach in depth.

Hi there,

First post to support, feel free to move if I shouldn't be commenting on an existing ticket.

I am experiencing this issue as well, and the behaviour is exhibited and repeatable in the RadControls demo application.

Go to the MultiColumnComboBox demo, select AutoFilter. In the filter box type "ALFKI" as you would quickly without necessarily looking at the results being returned to the screen. As soon as the entry is the last one the autofilter kicks in and is applied but the text cursor is moved immediately to the end of the string and you end up typing additional characters after the filter is applied and then losing the results. It's actually really quite annoying and I can't actually deploy my application with it exhibiting this behaviour.

A more preferable behaviour would be for the text string to be completed and the remaining portion of the string highlighted with the cursor remaining where it was. That seems to be a more natural and expected behaviour and similar to the existing dropdown control. With it this way, as much as it's great, it's almost too good and will end up annoying end users.

Kind Regards,

James

Alternatively, simply having the option on whether the text box string is appended to or not would be perfect. I thought this was controlled by the Autocomplete settings but that doesn't seem to have an affect on this.

Hello James,

The illustrated case is an expected behavior. This is known limitation, that we are planing to addressed in one of the next releases. In the meantime, I cannot provide you with a temporary solution due to internal implementation of RadMultiColumnComboBox control.

All the best,

I am also suffering from this issue and as a result, my app has failed UAT testing.

Is it possible to add a property to only allow valid entries to be entered, i.e the combo would restrict the entry of text to the values in the drop down? I guess it'd have to work like the dropdownlist, but allow filtering based on keypresses?

Just for my vote I would also like this option to be able to not auto select the last item in the list when auto filtering. That is a very annoying behaviour. The current behaviour is requiring the user to know at what point an item would be auto selected before they start typing or to type really slowly and wait to see if the letter just typed filters out all but one row. The current behaviour is forcing me to not select Telerik Windows Controls as a replacement for Infragistics which is really disapointing since overall I like Telerik better than Infragistics but that auto selecting behaviour is a real show stopper.
