I am using a GridView in a master - detail, MVVM, Prism scenario.  When I navigate to the master, I want to set the selected item to an item whose ID is passed in during navigation.  The difficulty I am having is that appears that the Selected Item is being set in the modelview before the GridView data loading is complete.  In debug, I can see that the Selected Item is getting set properly and PropertyChanged is raised for the operation.  Subsequent to this, the Selected Item is getting reset to a different value from the GridView via the TwoWay binding, I'm guessing after data loading has been completed by the GridView.  How can I ensure that the selection being made from within the viewmodel does not get overriden by the loading operation of the GridView?  Here are some code snippets:

Hi,

I am creating a generic grid solution based on the Telerik grid as a prototype to test the suitability of the Telerik components.

Our data layer can not send us typed objects. Instead it sends an object with an array of field names and an array of values.

Arrays
My first approach was to use a binding expression referencing the index to display i.e:


The grid does retrieve the values using this expression, but grouping, sorting and filtering are missing.

Dynamic object
Since this didn't work I thought I could trick the grid into thinking the model was strongly typed using a dynamic object that returned values based on the binding name:

This fixed grouping and sorting however filtering is still not working

I've have a simplified test project that demonstrates my findings, but the forum won't allow me to attach it. Any help resolving this issue would be most welcome.

Hello!

As it is currently designed in the telerik no mater what I do I always get the limits labels over Scale's path border.
But I would like to have all the labels inside the scale's bar as in attached image...

( <Gauges:LabelProperties Location="OverCenter" /> )

How is that possible?

Thank you

Hi,

I have used a candlestick and a barchart in same page. When I changed the zooming parameters and scrolling the scrollbar, the candlestick's DateTimeCategoricalAxis display has some problem, please see the picture.

Hi,

I would like my application to save the grid state (sort, column order, filters, etc) and then when restarted I would like to re-apply these settings.

I started playing around with this idea only to find the SortDescription and CompositeFilterDescription are not Serializable.  Can we please make these serializable in a future release?  Even better can we add the methods:
RadGridView.SaveGridState(string filename)
RadGridView.LoadGridState(string filename)

Thanks

Hi,

I'm having trouble changing the dictionary to en-GB when the RadRichTextBox control is hosted in a RadWindow rather than a standard window.
It will be easier to see some coding examples of my problem.

Initial Loading Code:


Notice that I'm using a class called RadWindowHelper2 and a method windowHelper_TraskBarDisplayed(). I obtained this code somewhere in these forums so that a taskbar item is displayed.
At the end of the initial code I then call LoadDictionary() to change the dictionary to en-GB.


RadWindowsHelper2 class

windowHelper_TaskBarDisplayed()


LoadDictionary()

I can get the window to load and radrichtextbox to show providing I do one of the following:

1. Comment out LoadDictionary() method call   (loads RadWindow with a taskbar icon but doesn't change dictionary)
2. Comment out the code that creates an instance of RadWindowHelper2   (loads RadWindow without a taskbar icon but does change dictionary to en-GB)

For some reason I cannot get both of the above methods to load together.

Here's the exception and stack trace when I try to show a taskbar icon and change the dictionary to en-GB:

Exception:
NullReferenceException was unhandled

Object reference not set to an instance of an object.

Hi There,

first i want to explain to you what i want, than how i solved it and finally what my problem is.

I was looking for a SelectionChangedEvent on a GridViewComboBoxColumn because based on the selection i have to calculate another property of my "RowItem".
e.g. A user change the value in my first column ( a GridViewComboBoxColumn ), so the value in column no 3 has to be calculated.

Because i didn't find an event, which i can use.

I created my own column, it work mostly:


My problem is now that i am unable to get the row item in my gridview to set the property for the third column.
Can somebody helps me by this issue? Or is it the wrong why to solve this problem?

Many thanks in advance for your cooperation

My tileView has tileItems that have an image thumbnail along with other things. The process that loads these images is a time-taking process. I want to load the image thumbnails only if the Tile item is within the viewable area. So if my current viewarea shows 50 tile items out of 100 tile items, I want to load the images for only those 50 that are visible. When the user scrolls the tileview and other tileitems come into view, then I want to load the images for these tileitems too.

Is there any event that I can use, to call my load image code....maybe something like tileitem post rendering or something.
I will be grateful for any code samples.
Thanks,
Subarna
