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.

Recurrence Rule / Occurrence Count IEnumerable Error

Hello,

I am having a problem referencing any of the iEnumerable properties on Occurrences collection for the RecurrenceRule class. It is working OK in one project (4.0 framework) but I am having compilation errors in the other project such as:

Error 179 'Count' is not a member of 'System.Collections.Generic.IEnumerable(Of Date)'.

The above error is happening with this code:

If parsedRule.Occurrences.Count > 0 Then

In my other project the above works OK. I've tried adding references to different framework system libraries but it doesn't seem to make any difference.

Any idea why the above would be happening? Am I missing a reference or do I need to change a reference? I am using the Q3 2014 UI AJAX ASP.NET controls.
