RadInput getting client side changes on postback

Hi,
Is there any way to get the changes that were made to a RadInput control on the client side when the page posts back? For example, I know that a RadTextBox can be set_visible() or enable() on the client side. How can I detect whether the box was visible/hidden or enabled/disabled by the client after the page posts back?

Toolbar Buttons not working on subsequent editors within tabs

I have an interface with several tabs and a RadMultiPage where all content is loaded so that you don't have to do a postback as you switch tabs. I have a RadEditor on 3 of the tabs with a custom toolbar (via toolbar file). The toolbar buttons work on the first editor, but when I click on a button in the second or third, It scrolls me to the top of the page and adds a # to the end of the URL in the browser address bar.

I'm using IE 11.

Any thoughts would be appreciated.

Thank you.

Get Filtered Data from Grid via Entity Framework

Good afternoon - using the Entity Framework / an Entity Data Source, I need to get the data the user has filtered from the Grid. What's the easiest way?

It seems difficult to iterate through the entire paged data-set getting ID's and then re-fetching all the rows based on the Primary Key/ID.

I've found a "double rebind" hack works quite well - though not sure on performance yet - but I'd be interested to hear the best options:

        private bool StoreInLocalVariable;

        private Collection<CustomerData> CustomerData;



protected

void btnGetData_Click(object sender, EventArgs e)

{

// Rebind grid without paging to get full data-set

                StoreInLocalVariable = true;

rgCustomerBalance.AllowPaging = false;

rgCustomerBalance.Rebind();

var result = CustomerData;

// Restore grid back to normal (i.e. with paging)

StoreInLocalVariable = false;

rgCustomerBalance.AllowPaging = true;

rgCustomerBalance.Rebind();

// Do something with Result

}

// Entity Data Source Selected

protected void edsCustomerData_Selected(object sender, EntityDataSourceSelectedEventArgs e)

{

if (StoreInLocalVariable)

{

CustomerData = new Collection<CustomerData>(e.Results.Cast<CustomerData>().ToList());

}

Possible to make telerik render html without any telerik css?

Hi,

I have an web app that is over 10 years old and has gone through many revisions and upgrades...we've been using telerik's ASP.Net controls for at least 8 years now.
We can't really rewrite the entire thing to MVC, but I need the web app to match our mobile app (based on Google Material) better.
I want to step away from the heavy CSS use of the built in telerik themes.

I've had some luck incorporating this CSS theme framework that is based on Google material:
http://materializecss.com/

But in many cases, the telerik CSS is overriding or conflicting with the Materialize framework.

It would be nice if either you guys provided a Material theme for ASP.NET AJAX, or if I could keep using the Materialize framework by getting my current app using ASP.NET AJAX to push out cleaner html.

Thanks,
Sam

Button server side focus method

Does anyone have a resolution for the RadButton not being focused on a Page_Load event?

ASP button you can set the .focus() in the page load event and it is truly focused when the page is displayed. RadButton doesn't work.

Is it possible to get all Theme names from SkinManager?

Is there a way in code behind to pull all possible Theme names from the Skin Manager into a string array?
I was thinking it might be stored in RadSkinManager.Skins but I didnt find it there. If it is possible please
show code example.

Thanks,
