RadCombobox Editing the Value

[victor]

Hi ,

Here is Problem with RadCombobox Editing the Binding Value .

Scenario:-I had bind the Collection to a RadCombobox which is  inside the grid with DataTemplate (code snap Provided With attachment), I selected the Value from Dropdown and went to next Column , next Come back to the same I want to edit that selected value instead of Selecting from dropdown ex:- I choose 8.50 from dropdown and  want to edit this value to 85.50 ,I focused the cursor inside the combobox between 8 and dot and try to enter the value 5 in between,that time the entire value is lost and  overwrites number 5 and  stays in box and I give the Property IsEditable = true also , how to achieve this Editing ? Can any one help on this

 

Thanks

Victor

Hi Victor,

By default when the user types in the editable RadComboBox searching and auto-completing to item from the ItemsSource is performed. Therefore when the 85.50 is entered it searches for item with DiscountPrice euqals to 85.50 and when such item is not found the selection is cleared.

So if you want to edit the value of the DiscountPrice for the selected item you need first to disable the search functionality by setting the "IsTextSearchEnabled" property to false. This however will not update the DiscountPrice  value of the selected item and in order to achieve this behavior you need to synchronize it with the Text of the ComboBox:

    1. By direct binding:

Text="{Binding SelectedItem.DiscountPrice, Mode=TwoWay, ElementName=combo}"

    2. By binding to the view model property holding the selected item:

Text="{Binding PriceLevelTemplateCollection.DiscountPrice, Mode=TwoWay}"

It would be great if you can give it a try and let us know if this works for you.
Also if you have any other questions, please don't hesitate to write us.
