Hi,

I am using rad async upload controle, is it possible to get file size when file is dragged and dropped?

Hi,

I am going through an issue with Telerik controls, all my Telterik Control because disabled, like RadEditor, RadListBox and RadAutoComplete. I installed the Telerik Version=2016.1.113.35, before that I was having the Telerik Version=2015.2.623.45. After installing I converted all my Application and its related components from .Net 3.5 to .Net 4.0, now all my Telerik Controls became disabled, the ones which were working before also became disabled.

Any help what could the reason and solution for it, any think like a link, a code snippet or even a suggestion would be helpful.

Here is my code:

So I am trying to set the ImagesFolderPath at runtime, but am having problems please help.

Let me setup the scenario first.... I have a webpage that has several different controls.  One control is a dropdown list that contains numeric codes.  When a code is selected it populates the rest of the page.  I want to set the ImagesFolderPath, once this numeric code is selected.  I have tried putting code in the Load and Databinding events the ImageGallery never reloads.  The control just sits on the page and does not appear to ever reload or rebind with the new ImagesFolderPath.


Please help

I have two RadDatePicker's. One holds a "date sent" value and another one a "date paid". The date sent value has to be before the date paid AND the date paid RadDatePicker has to be disabled until a date sent value has been set in a form. How would I achieve this? I thought a CompareValidator on the second control would prevent postback if the first input is empty but it seems that's not the case.

 

FYI I cannot use client side scripts on the same aspx page. I have a separate JavaScript folder that holds all my scripts and I cannot call $find("<%=RadDatePicker1.ClientID%>") . 

 

Help would be greatly appreciated. 

I have set all controls rendering mode to lightweight via the web config:

<add key="Telerik.Web.UI.RenderMode" value="lightweight" />

 

Running the site locally in chrome and in IE11 renders the output lightweight as as expected.

Once deployed to a server and set in IE as an intranet site, the controls are then rendered classic.

Chrome renders as lightweight, but IE seems then seems ignore this global setting in the web config. The page has the relevant meta tag to switch the document mode to IE=Edge but the rendered HTML is still in classic. Meaning all of our CSS is now useless.

Could someone please point out what I am missing here.

Thanks

 

Additional Info:

• The controls don't have individual render mode properties on them.
• The setting is still there in the web config after deployment.

 

 

 

I am trying to show toolbar dropdown text like:

 

   Dim dropDown As RadToolBarDropDown = New RadToolBarDropDown("PageSize")
            dropDown.Text = GetGlobalResourceObject("Insight", "Per pagina")

This ends up with the following sourcecode:

 

<span class="rtbText rtbHidden">Per pagina</span>

What could be wrong here? Skin = Material 2016.2.607.45

How can I programatically set the default pagesize in a grid depending on the number of items in the grid? I want it to be proportionate to the number of total items. Basically limiting the paging to a certain number of pages, rather than the number of items per page. I’ve seen some examples to do this when using the combobox for the PagerStyle, but we’re using the “NextPrevNumericAndAdvanced” and I want it to be the default value. Thanks.

We are using Telerik's radgrid for a Kentico site.  We're having a major problem with the user's dashboard.  When a user adds the data grid widget to their dashboard, it posts back and there's the grid. IF they then add a second one, it throws the below error.
If they add a grid, then after it post back, revisits the page, they can add another with no issue.  Same goes for deletions of the widgets, they can delete the first, but if they don't revisit the page so it's not a postback, it throws an error.
The error seems to be occurring in the grid between the Load and Prerender, probably with the PostbackChangeNotification or PostbackEvent.
I can't get the debugger to catch it at all.  There are save and load states in the code, here's the error and some of the code.

Seems that in code behind the AllowFilteringByColumn property is always set to false at all phases of life cycle prior to the data binding stages. Code example like below for example is always returning me false.:

 

 

Our requirement is to apply a certain DOM class to all grids site-wise. If AllowFilteringByColumn is not propertly populated before databinding is there another way to determine whether filtering is enabled?

What is the proper way to set FilterTextBoxLabel from codebehind?

RadFileExplorer1.FilterTextBoxLabel= GetGlobalResourceObject("Insight", "Filter")

Doesn't work in _Load nor in _Init
