Within DistinctValuesLoading(), I added 3 new strings to distinct values: [2], [4] and [6].
Their purpose is to filter by length, e.g. [2] should only show rows that have a string of length 2 in this column.

Is their any way to achieve this in Filtering() event ?
Or is their another way to reach my goal ?

My application is built in WPF.  I have a class called "MyWindow" that descends from the WPF Window class.  I have another class called "MyDialog" that also descends from the WPF Window class.  These two classes have a uniform look and functionality so it made sense to create my own base classes for the applicaiton.  The application is to be used on touch screen equipped laptops in police cars, so I've made everything bigger, to make it easier for people with large fingers to interact with the application.

My application has a login dialog that descends from the MyDialog class.  During program startup, the application performs a number of steps, including loading a resource dictionary that contains brushes that are used to draw the application's controls.  Again, part of the whole unified look.

The login dialog has a RadComboBox on it.  The app.xaml has a custom template for RadComboBoxes that increases the width of   the drop down button on the control.  The first time the login dialog is displayed, however, this template is not applied; the drop down button is the normal width.  However, if you enter a wrong password & click login, the dialog is redrawn and this time the drop down button is the right width.

Why is the width of the RadComboBox wrong the first time but right the second time, even though every other aspect of the dialog is drawn right the first time?  I don't even know what code to include to help you guys help me on this.  Any ideas?

Hi,

After encountering a few performance issues with the Dynamic Layer, would like some clarification on best practices of using the Dynamic Layer.

The following 2 forum posts are from 2010 - http://www.telerik.com/community/forums/wpf/map/working-with-dynamic-layers-and-mapshapereaders.aspx and http://www.telerik.com/community/forums/wpf/map/radmap-dynamiclayer-performance-problem.aspx

I am currently using the below code to only return those geometries which are in the current extents, rather then dealing with this at a fairly low level, does the Dynamic Layer have any of this functionality included?

Many thanks,

Adnan

Hello,

Is it possible to add a click event to the time event so that we can navigate user to different pages if they click on the time event in timeline?

Thanks

Hi There, 

We have a requirement for lots of different buttons with their appropriate look and feel. I have created my own Theme where the buttons would each take on their own style, The required behavior would be to have our own style for each of the buttons, however, if one of your themes were chosen, then it would just use that for each Button Style,

The buttons all inherit from RadButton, However, When we use our own Theme, the buttons look the way they should in design time. eg ButtonType1 =  Green, ButtonType2 = Red, NormalRadButton = Orange. However, when I then run the application all the buttons change to the NormalRadButton of Orange. This would be the required behavior when using a Telerik theme.

I have a small demo app that shows the behavior, however, you don't seem to allow these type of uploads, I have attached screen shots of the demo app, 

I could send you the demo app if required

Thanks,

Yuri

Hi,

I am facing a problem when I am trying to upgrade the telerik binaries from version "2009.3.1314.1030" to "2012.1.326.1050". I have added the reference of the assembly "Telerik.Windows.Controls.dll" in my project and after that the statement 
using Telerik.Windows.Controls ; 

is throwing an error like the below:
The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?)

I have .net framework 4 installed on my machine.

One other interesting thing that I have observed is that when I have tried to open this assembly in the Object Browser from Visual Studio 2010, it is not opening the assembly.

Any suggestions/ideas to fix this issue?

Thanks,
Vijay

I am trying to make the background color of the first row in my grid blue. here is what I am trying in c#.

 for (int i = 0; i < rgvAlarmLog.ColumnCount; i++)
                            {
                                rgvAlarmLog.Rows[rowCount].Cells[i].Value = HeaderRowSplit[i];
                                rgvAlarmLog.Rows[rowCount].Cells[i].Style.BackColor = System.Drawing.Color.Black;
                            }

I have another loop that goes through the rows and that is the rowcount variable. There is no visible color change when I do this. What am I doing wrong? It is a radgridview object. I have looked at similar post and tried their code to no avail. Any advice? Thanks

Hi,

I'm trying to implement a copy function.

In XAML I did the following:


How can I get access to the CommandParameter "copy" in the code-behind so that I can determine that a copy is needed instead of a regular AddNew?

Thanks in advance

I can't seem to get the DataForm to sync with the GridView.

I've got both controls bound via ItemsSource to the same collection in my viewmodel. But when the form loads in debug, there doesn't appear to be any records. If I create a header for the DataForm that displays Items.Count, it correctly shows the number of Items in the collection. But the current item isn't working. When I click on a Navigation button or the new button, I get the following error:

System.Reflection.TargetParameterCountException occurred
