I have a support ticket going for this but having 24 hours go by for every response is pretty slow. I upgraded to the latest with the Telerik Control Panel and now no tool box items. I have followed all instructions for removing tbd files and even registry entries, but no luck. I even uninstalled and went back a version and still can't get tool box items.

Any one else had this problem? Any real fixes besides the usual instructions, which are not working for me?

thanks

Get current RowID of RadGrid on OnClientSelectedIndexChanged event of RadComboBox in a GridTemplateColumn

Telerik Support,

I have a RadGrid in Edit mode. The RadGrid has several GridTemplateColumn columns containing both RadComboBox and RadTextBox controls.

On the OnClientSelectedIndexChanged event of the RadComboBox column, I need to interact with the RadTextBox and RadComboBox controls in the other GridTemplateColumn(s) on the current RadGrid row. To accomplish this I will need the IndexID of the RadGrid row containing the RadComboBox control that the user changed the value of. However, I cannot find a good way to discover the row's IndexID inside the OnClicentSelectedIndexChanged event.

Can you suggest a possible solution for this challenge?

Please note that my business requirements state the solution must be entirely client-side (no AJAX postbacks).

Thanks in advance for your help,
Wes

Bar Chart XAxis value field issue

Hi

Telerik Team,

Please find attached screen shot,
As per given screen shot you can see the value of XAxis witch shows the Name[ID] format, Both Name and Id are used to perform drill operation, I have set this values using `DataLabelsField`

Now what I want to do is,I just want to show Name not ID,Is there any way to show only Label not Id i.e Is there any provision to set value like DataValueField to set Value(Id) and DataLabelField to set Label(Name).
(DataValueField is just imaginary name)

So that this Id field will be used to perform drill operation. but User can not able to see it.

Thanks

Multiple Pointers on RadLinearGauge - Pointer Values Gone After Postback

Hi. I can't figure this one out.

I recently upgraded to Ajax UI 2016.2.504.45 specifically so I could make use of the new Multiple Pointers feature. I updated my controls and code to add multiple pointers dynamically, rather than just setting the value of the single pointer dynamically. And this works great.

My issue is that after postback the gauge loads and my pointers have been removed. However the Scale ranges that I am adding dynamically are retained and correct.

I run a number of intense calculations on a button click which populates the RadLinearGauge with pointers, I don't want to have to run this on every postback just to ensure that the pointers are present. The only thing I can think is that this is a bug in the RadLinearGauge.

Reproducible Example:

HTML

01.<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>

02.

03.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

AreaSeries Transparency

Hello,

I have a few RadHtmlChart's rendered on my page. Each has a dynamic PlotBand setting to highlight the target on each chart. I can control the alpha setting on these PlotBands, but I can't seem to do so on the actual series itself...

I want the area representing the data to have a 0 alpha setting as to not show what's behind it.

Any thoughts?

Thanks!
