Hello Telerik Team,

<Reposting this thread from ComboBox forum to this Grid forum, as I thought it is more appropriate to put it here.>

Original link: http://www.telerik.com/forums/need-help-on-radcombobox-multi-checkbox-filtering-not-working

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..

http://www.telerik.com/forums/how-to-persist-dropdownlist-selected-index-and-value-on-postback-from-radgrid-filtertemplate#GW3MyQLmVEmy8XzsmrHzeQ

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:

http://www.telerik.com/support/code-library/multi-selection-radcombobox-for-filtering-grid#2351833

Please check my combined aspx code and code behind below.
ASPX Code:

Code Behind:

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.

I have been trying to implement a RadGrid with batch edit mode enabled. It is essentially just a grid that makes calls to entity framework to update data in a SQL database. It works fine sometimes, but, usually after I've saved changes a few times, all AJAX calls stop working on the page. I have been trying a lot of different ways of reproducing the bug consistently, but I can't figure out how. I usually just add a few records, and edit a few records, save, then repeat the process several times until eventually it stops working. When I press the button in this state, it will flash the loading symbol for a fraction of a second, but nothing else happens. Normally, the loading symbol shows for a second or two, then the grid and database update. The OnUpdateCommand, OnInsertCommand, and any other commands do not fire when in the erroneous state, and other controls on the page that use AJAX don't work anymore. I can't seem to find any code behind method that gets called upon attempting to call them. The pertinent (I think) code is in the page XAML file GateProduct.aspx, the control XAML file Checklist.ascx that contains the RadGrid, and the codebehind for the control Checklist.ascx.cs.

We have 2 tabstrips on one page. One is used as the overall tabstrip and the other as steps through a form submission. We're using the lightweight rendermode and are modifying the styles on the steps tabstrip using css. We'd like to remove the bottom border on the steps tabscrip but not on the primary. When we use:

html .rtsTop .rtsLevel1 {
    border-bottom: 0;
}

It removes it from both. If we try to just add the border-bottom attribute to the assigned class for the steps tabstrip it doesn't seem to work. Is there a good way to do this?

Also, is there a documentation page available that shows the CSS options in the lightweight rendermode for TabStrip. We couldn't seem to find it.

thanks

This is the code for the rad scheduler.

Hello Team, 

We have a new feature in application where we will have a page with one RadTreeView and two or three RadEditor.

The RadTreeView will be added to display the list of images and user will drag the image and drop to any editor.

As per the demo the one Treeview and one Editor is working okay. But when I add two or more Editor the dropping is not working in all editor. We can drop the image only the last editor.  I also tried to get the destination item (editor or div ) in OnClientNodeDropping event but I did not get the destination item. If we get it when we can add the image in destination item (editor or div ). 

Dear expert, is there anyway to get the Id of destination item in  OnClientNodeDropping event?

Or 

Any solution of this problem problem.

Thanks

I don't know how this has been missed in the documentation. Alternatively, it's well hidden in some obscure place. I'm trying to filter a column of a detail table using a static radcombobox. Using the instructions from the "Filter Template" documentation (http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/functionality/filtering/filter-template) I'm not seeing any filtering in action on the detail table. The documentation for "Detail Tables Filtering" is rather useless (http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/functionality/filtering/detail-tables-filtering).

Someone show me where I'm going wrong?
