[Solved] DropdownList doesn't recognize key strokes quickly

[Ashok]

Go to Telerik Demo for ComboBox/Dropdown, pick Dropdown list, try pressing key board key like "A" and "C" alternatively with 1 to 2 sec apart... one will see that DropDownList doesn't change the value. If you Press key "A", wait for 3-4 sec for first item of with "A" selected, then press "C", it will select first value of "C".

Why we see performance issue with MVC DropDown? Is this a bug? Is there any workaround?

This is not the case with regular telerik drop down control.

Hello Tejas,

 
This is not a performance issue. This behavior is by design. The DropDownList UI control remember for a while the end user input. In this case if you are typing fast "A" and then "C", this means that the dropdownlist will search for a word which starts with "AC". If end user presses "A" and then waits for a while ( 1000ms to be more specific) "C" will replace "A". Select HTML element has the same behavior.

Hello Georgi,

Thanks for response. I understand it better now. However this is making user of our website a bit upset. Is there a way, i can avoid 1000ms wait, when I am using control as dropdown list?

For e.g. Lots of website where you do registeration, and if you need to select "state", it works faster as there is no such delay.

Hello Tejas,

 
Currently it is not available to control the aforementioned delay. However, we decide to introduce Delay method which will allow you to set specific delay. This feature will be available with the next internal build of Telerik extensions for ASP.NET MVC.

I hope this helps.

I have the same question as Abigail.  Was this functionality added to the DropDownList?
