Problem when clear selected value

Hello Wahid,

I would suggest to call the following after reload()

Hi Georgi,
This worked when the ComboBox field doesn't has a "Previous Value" as in create status.
But when i try to modify an old value by cascading this ComboBox the old value still stuck 

Hi Wahid,

Could you please provide a sample code so I can see your current implementation?


Kind regards,

Here is an example :

I'm editing some product information which contains "RootCategoryId" and "SubCategoryId".
So when i change the RootCategoryId value the SubCategories ComboBox should be reload with the new values and it do indeed but it keeps the old value id as text value until i select the new value.

function onRootCategoryComboChange(e) {
    var combo = $("#SubCategoryId").data("tComboBox");
    if ($(combo).length > 0) {
        combo.value('');
        combo.text('');
        combo.dataBind();
        combo.reload();
    }
}

Here in the attachments two files to make the idea clear.

Update:
Now this worked 

But i think this isn't the right way is it ??

Hello Wahid,

Basically you can subscribe a JavaScript function to the OnDataBound event of the sub ComboBox which 
can simply select the first item in the collection.
e.g.

Hi, 

I encountered the same problem where reload() does not clear the previously selected value.
My server can return an empty list as dropdown values, which means there are no valid values, thus the dropdown should be empty.
However, I am left with the value I previously selected, and there is no way to get rid of it.
Setting text() and value() doesn't work, text  is changed to blank but value is still the original  value I selected.
Any workaround is appreciated.

Thanks,
Yang
