Telerik.Win Assembiles installed in my GAC - Correct MSI, or where to find it?

Hi there,

I'm working in a pretty big IT shop and it appears that 32 Telerik.WinControls where installed with version 2014.2.617.20 by one of the IT staff here.

The downstream issue I'm having is when trying to run the latest Telerik Demos App "Demos - Telerik UI for WPF", I get a DLL mismatch error.

Could not load file or assembly 'Telerik.Windows.Controls, Version=2016.1.112.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies, The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

I was able to trace back via my log files that this was the file that was used to install these assemblies: "Telerik_UI_for_WinForms_2014_2_617.msi"

I want to mainly run the demo app to show to influential business partners what Telerik Controls can do, but these current ones installed on my GAC are blocking me from using the WPF Demo App

Would the best course of action be to find this MSI somewhere, and un-install it, or download it from Telerik (if it still exists)?

Or, is the conflict something else?

Much appreciate any feedback someone can provide.

Cheers!

[Solved] set hand cursor pointer on cell hover

Hello Telerik,

I am trying to accomplish this

http://www.telerik.com/forums/gridview-cell-mousehover-hand-cursor

but for WPF.

Basically set a hand cursor when it is hovering on the "Name" cell.

I want to do a link-like visual to my cell (if you could also help on this, much appreciated)

I have tried to handle events like

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" MouseEnter="GridViewDataColumn_MouseEnter" GotMouseCapture="GridViewDataColumn_GotMouseCapture" MouseMove="GridViewDataColumn_MouseMove" IsMouseCaptureWithinChanged="GridViewDataColumn_IsMouseCaptureWithinChanged" CellStyleSelector="{StaticResource NameLengthTemplateSelector}"/>

private void GridViewDataColumn_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)

{

}

private void GridViewDataColumn_GotMouseCapture(object sender, System.Windows.Input.MouseEventArgs e)

{

}

private void GridViewDataColumn_MouseMove(object sender, System.Windows.Input.MouseEventArgs e)

{

}

private void GridViewDataColumn_IsMouseCaptureWithinChanged(object sender, DependencyPropertyChangedEventArgs e)

{

}

but none of them gets hit by my breakpoint when I hover my cell

please help!

cheers

StyleManager.Theme does not exsist

I have an old .net application that is no longer supported or being devolped. I need to make some changes and would also like to fancy up the interface. I used justdecompile to decompile it but I am getting a lot of XAML errors -

The property 'StyleManager.Theme' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'. Line 57 Position 116

.
The application uses

Telerik.Windows.Controls.Data.dll,Telerik.Windows.Controls.dll,Telerik.Windows.Controls.Docking.dll, Telerik.Windows.Controls.Input.dll, Telerik.Windows.Controls.Navigation.dll,Telerik.Windows.Data.dll

I ran the upgrade wizard on the project and it completed without any error I think it upgraded from Telerik version 2013. Can I upgrade this project to have no XAML and only use implictit styles?

[Solved] How to Customize a RowStyle

Hello Telerik,

I am trying to customize a RowStyle, depending on what comes from the database.

My first attempt is very simple, but I am getting this error when running

An unhandled exception of type 'System.InvalidOperationException' occurred in PresentationFramework.dll
Additional information: 'DataGridRow' TargetType does not match type of element 'GridViewRow'.

the error makes sense, since telerik GridView is something different than a DataGrid

but I am trying to implement the same approach.

I think it will be more clear when you see my code below:

<telerik:RadGridView Name="RadGridView" ItemsSource="{Binding View}" Style="{StaticResource VitorStyle}" AutoGenerateColumns="False">

<Style x:Key="VitorStyle" TargetType="telerik:RadGridView" >

<Setter Property="RowStyle">

<Setter.Value>

<Style TargetType="DataGridRow">

<Style.Triggers>

<DataTrigger Binding="{Binding Name}" Value="Anastacia Santana">

<Setter Property="Background" Value="Red"></Setter>

</DataTrigger>

<DataTrigger Binding="{Binding Name}" Value="Ana Taylor">

<Setter Property="Background" Value="DarkOrchid"></Setter>

</DataTrigger>

</Style.Triggers>

</Style>

</Setter.Value>

</Setter>

</Style>

As a kickoff test, I would like all Anastacia Santana rows to be RED and all Ana Taylor to be DarkOrchid.

My following tests should envolve a bit wether it is true or false, or a sum result wether it is positive or negative.

Can you please show me the best way to achieve this?

as a side note, I would like to keep my XAML as clean as possible. Thus the use of the resource file

Thank you very much!

Chartview with ChartDataSource and Custom Aggregate Function

Hello,

I've been working with the Chartview lately, and have a chart with a datetimecategorical axis, that utilizes a chartdatasource to group datapoints when the chart is zoomed out. My problem is that the default aggregation function being applied takes the average of grouped datapoints, and I am looking for the sum. To my knowledge there is no sumfunction of type ChartAggregateFunction, and very little information detailing how I go about creating a custom function to gain that functionality.

I was wondering if you could show me an example detailing how to go about solving my problem.
