Hello Telerik Team,
<Reposting this thread from ComboBox forum to this Grid forum, as I thought it is more appropriate to put it here.>
I can't seem to make multiple checkbox filtering work on a RadComboBox inside a RadGrid using a Filter Template.
I have been working on the examples given on the thread below for several days already..
Particularly, I used Eyup's sample solution of RadGridFilterComboClientAndServerDataBinding and modified the DataSource to have advance data binding, as I need to populate my RadComboBox in the code behind. But this sample code only supported single item filtering..
So I used the code coming from SearchMultipleValues.aspx and SearchMultipleValues.aspx.cs to implement the multi checkbox filtering. This code can be found on Eyup's post below, inside RadGridFilterMultipleChecked.zip:
Please check my combined aspx code and code behind below.
I added a new column, "Quantity", which will be filtered using multi
checkbox filtering. This is our focus which is not working.. This column
is populated inside the GetGridSource(). Filter values are binded to
the RadComboBox using RadComboBoxQuantity_DataBinding event, setting it
to the same data source of the RadGrid. (I know I should bind distinct
values here, but just for the purpose of an example I haven't updated
the code yet.)
Selecting several items from the combobox and clicking ImageButton1, multi checkbox filtering does not work..
Note: I put Filter="Contains" in the RadComboBox property as I read somewhere here and in the documentation that this will enable the textfield in the combo box so the user can type, which I also need.
I am currently stuck using Telerik.Web.UI, Version=2012.3.1308.35. Would anyone know why the multi checkbox filtering does not work?
Any help is appreciated.. Thank you in advance.
