I have a potentially large database whom I'm trying to query for just the items I want displayed on the page I'm looking at. I understand how to use LINQ take and skip to grab the correct range for each page.

What I am struggling with is setting the RadDataPager.PageCount to a value which would reflect the database's collection size and not the size of the collection in memory. I've tried binding ItemCount to a property that tracks the database collection size similarly to this http://www.telerik.com/forums/itemcount-binding.To my understanding ItemCount in combination with a PageSize binding should create the correct number of pages. I.E. 1 of X.

The question then is; is it possible to set the PageCount to a value that is separate from the size of the collection that the RadDataPager is bound to? 

Hi,

I was asked to implement the Excel-like arrow key navigation behavior for RadGridView.

These days users use Microsoft products as a standard. In Excel:

1. After users double click on a cell, with or without making any changes, users cannot leave the cell using arrow keys.

    They can leave the cell by clicking on other cell or using Tab

2. When users enter a cell by Tab or one single mouse clicking, with or without making any changes, users can leave the cell using arrow keys.

I want to do the same in RadGridView.

Thanks in advance for help.

I have attached a screenshot of my visual studio project where although I have basically copied your toolbar example the 2 buttons are showing vertically and not horizontally. Any ideas what's wrong?

Hi,

i'm facing an issue with RadDiagram in WPF.
I'm using the diagram in MVVM by using the GraphSource in order to populate it. 
I'm using your OrgChart project as sample to develop my application.
The app works perfectly the first time i startup it and the RadDiagram is populated correctly.
But whenever i try to modify the GraphSource (via "PopulateGraphSource" method as you use in OrgChart project) and then i layout my diagram, i get not all shapes displayed correctly on screen. I mean: the diagram route is correct, but some shapes are wrong and some others are not displayed.
I do not understand the issue, because it happens even if i populate the GraphSource with the same data that i use at startup time (At startup it works, at a second time it doesn't work, with same data).
The issue happens only when i call the "PopulateGraphSource" a second time. If i just call the Layout method of the diagram without calling "PopulateGraphSource", everything works correctly. But i need to change my GraphSource during the execution of the application.

The question has already been asked by another user but i guess he has exactly my issue at this link: http://www.telerik.com/forums/dynamically-change-graphsource-through-populategraphsource-method
Thank you in advance for your help.

Currently a bookmark can be inserted by using the RadRichTextbox method InsertBookmark().

Is there a way to insert a bookmark by just using the methods on RadDocument?

 

Hi,

I'm binding RadGridView ItemsSource to ObservableCollection<ExpandoObject> because I need to display the data without knowledge of its type and schema. Values are presented correctly in grid, but when I'm typing anything in search - no results are presented. Here is sample solution illustrating this problem, so that you can help me solve this problem.

Hello. Could you tell how to catch the coordinates of the connection Shape-Shape? For example, a Shape which has 3 inputs, the user connects the inputs and we need to know what exactly the entrance was summed up connection

Hi All

We are using WPF Telerik RadGrid to display real time data. 
We have pre-configured list of values which need to display on the filter of specific column.
We want to display the list of all such values in the filter column and if that values present in the RadGrid datasource or not still we want to display it with checkbox of filter on the column.
Currently, what happens, if we have pre-configured value in the RadGrid data-source then it is available in the filter column.
So the idea here is that, We want to show our own list of filterable values on the specific column.
For example, in the attached screen shot.
We are seeing Country column with Name. This grid is showing only countries what available in the Grid data source.
We want to show all countries in the "Select All" section of filter.
How can we achieve this?

Is is make sense?

Thank you
