I am unable to get the RadGrid EditItemTemplate RadComboBox with checkboxes=ture selected items are empty in RadGrid BatchEdit event. Basically I put the RadComboBox in RadGrid EditItemTemplate and selecting the multiple of RadCombo box and try get those selected item in RadGrid BatchEdit event to save into db, but RadComboBax seletedItems count is empty and I am not able to get the selected items of RadcomboBox. 

Instead of RadComboBax if I use the DropDownList I am to get the selected value in Grid BatchEdit event, but my requirement is need to seleted the more than one item so I am using RadComboBox. Here the below is my code.

Hi!,

TargetFramework: 4.5.2

DLL from C:\Program Files (x86)\Progress\Telerik UI for ASP.NET AJAX R2 2020\Bin45

Starting first default page debugger in Visual Studio give me Exception Unhanded: DOMException: Failed to execute 'querySelectorAll' on 'Element': '*,:x' is not a valid selector. Visual stop just after comment below (Please check attachment).

Also loading pages is slow. Maybe because this exception occurs 2 times per each page (on loading).

Page is simple:

Hello,

I would like my tooltip not to show the x an y coordinates on my ScatterSeries, but another string (ProjectName). ProjectName is a column in my datatable that I'm using as the source.

Can you please tell me what's wrong  with the following code? It shows undefined when I hover over a plot item.

 scatterSeries.TooltipsAppearance.ClientTemplate = "#=dataItem.projectname#";

Thank you

Hi All,

I have a templated combobox like so:

The radcombo is databound to a generic list of objects that have the attributes listed.  I can easily add a cssclass name attrbute to each object int the list or a hexcolor attribute etc.  When rendered it looks like the attached file.  My question is assuming I have a cssclass called .makered {..}  how do I apply it to items that have a level of 3 on the risklevel column for ONLY the risk level column in the template,  ie, for specific columns and specific items.  Applying the class to the whole row would work fine too.  Items are databound...not added in the markup.  Also any help lining up the columns would be helpful.

Thanks!

I am trying to open the context menu of a DetailTable in the MasterTableView. There is only 1 table and it has the columns that we want the users to select columns. Honestly, this should be something out of coding, like as header option. RIght clicking is not something the user would know, unless told. A button is perfectly normal. So i tried a button and it doesnt open the Context Menu of the GridTableView nested in the MasterTableView
