Issues with page rendering with UI for ASP.NET AJAX R3 2016 update

We have an application that relies heavily on Telerik controls and noticed with the most recent update (ASP.NET AJAX R3 2016) we have some rendering issues in Chrome. (See attached pictures). Firefox, IE, etc. are all fine. You can see that there is a significant amount of padding between the two checkboxes.

This is only happening on our development environment and not our live environment. Is there something with this new update that would cause rendering issues in Chrome?

MDX query

Hi,

I am using the RadPivotGrid to navigate a OLAP cube on Microsoft Analysis Service. The control connects to the cube through Adomd connection string.
I would like to retrieve the MDX query releated to my navigation. Is it possible?

Thanks in advance.

SetImageProperties_Constrain not working

When changing the properties of an image, an icon of a broken paperclip shows next to the height and width, which (if clicked) forces the proportions to be constrained.

Inside RadEditorProvider/App_LocalResources/RadEditor.Dialogs.resx, there is a Name of "SetImageProperties_Constrain" with a value of "Constrain". However, the properties window is always not-constrained by default... and must be clicked each time.

Our website is hosted on DNN7, which by default contains the Telerik RadEditor.

Any ideas on how to set it to be constrained by default?

Thanks,

-Adam

How can I check and validate dimensions of a picture before upload?

In my web application I use a AsyncUpload to load the picture of each user to their personal page.
I need to limit the dimensions (height and width) of uploaded images.

How can I validate the height and width of the images before they are loaded? Or convert them to the dimensions I want?
I need images have the dimensions 150x100
I have the following code to validate file type and file size of uploaded images.

foreach (UploadedFile file in LogoUpload.UploadedFiles)

{

//string filetype = LogoUpload.PostedFile.ContentType;

string filetype = file.ContentType;

long filesize = file.ContentLength;

byte [] input = new byte[filesize - 1];

long maxFileSize = 1024;

if (filesize > maxFileSize)

{

base.OnUIValidation("The file is too big.");

return;

}

string[] acceptedFileTypes = new string[3];

acceptedFileTypes[0] = "image/jpg";

acceptedFileTypes[1] = "image/jpeg";

acceptedFileTypes[2] = "image/jpeg";

bool acceptFile = false;

//should we accept the file?

for (int i = 0; i <= 2; i++)

{

if (filetype == acceptedFileTypes[i])

{

//accept the file, yay!

acceptFile = true;

}

Error Uncaught TypeError: Cannot read property 'ajaxRequest' of null

Hi, I have an ascx file that contains a RadNotification and a timer.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function OnClientUpdated(sender, args) {

sender.show()

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("content");

}

function UpdateWithoutPopup() {

var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");

ajaxManager.ajaxRequest(arguments);

}

</script>

</telerik:RadCodeBlock>

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Timer1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadNotification1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<asp:Timer ID="Timer1" runat="server" Interval="6000" OnTick="Timer1_Tick" />

<telerik:RadNotification RenderMode="Lightweight" id="RadNotification1" runat="server" loadcontenton="EveryShow"

width="300" height="150" animation="Fade" enableroundedcorners="true" enableshadow="true"

title="Received messages" offsetx="-20" offsety="-20" onclientupdated="OnClientUpdated"

titleicon="none" autoclosedelay="5000" Skin="Bootstrap">

<ContentTemplate>

<asp:Image ID="Image1" runat="server" CssClass="Max75" />

<asp:Literal ID="lbl" runat="server"></asp:Literal>

</ContentTemplate>

</telerik:RadNotification>

the timer makes the checks and if necessary displays a popup, another calls a function

public void Timer1_Tick(object sender, EventArgs e)

{

if (Check())

{

RadNotification1.Show();

}

else

{

string script = "UpdateWithoutPopup()";

ScriptManager.RegisterStartupScript(Page, typeof(Page), "myscript", script, true);

}

When I show the popup everything works fine when if I call the error function I get the error:

default.aspx:502 Uncaught TypeError: Cannot read property 'ajaxRequest' of null

how do I fix?

thanks in advance

RadTextBox - Password Mode

How do you get the EmptyMessage to show up when using password mode. It looks really funny when the username has the text in there but the password box is empty.

Setting CSS styles from code behind

Hi,
I am using a rad org chart. Basically I want to apply certain CSS styles based on a condition.
I have figured out how to just override a css styles:

.rocToolbar_Metro .rocToolbarButton { background-color: #32b330 !important;}

But I can’t figure out how to do this conditionally via the code behind, so saying if condition == 1 then apply this:

.rocToolbar_Metro .rocToolbarButton { background-color: #32b330 !important;}

Else apply this:

.rocToolbar_Metro .rocToolbarButton { background-color: #25a0da !important;}

I am planning to do this within the NodeDataBound event. Any suggestions appreciated.
Thanks.
