TargetType GridCell does not match Element of Type GridCell

[Tom Oeben]

Hi all,

i am just running in an strange Error and need help finding a solution.

We just updated from VS 2019 to 2022. Same Project no changes.

Debugging on "old PC" without any error. Running on Machine with VS 2022 i get the above error.

I found that this is generating the error:

<syncfusion:GridTextColumn.CellStyle>

                        <Style TargetType="syncfusion:GridCell">

                            <Style.Triggers>

                                <DataTrigger Binding="{Binding Path=Dringlichkeit}" Value="Fertig ausgewertet">

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

                                    <Setter Property="Foreground" Value="White" />

                                </DataTrigger>

                                <DataTrigger Binding="{Binding Path=Dringlichkeit}" Value="Sofort">

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

                                </DataTrigger>

                                <DataTrigger Binding="{Binding Path=Dringlichkeit}" Value="Eilig">

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

                                </DataTrigger>

                                <DataTrigger Binding="{Binding Path=Dringlichkeit}" Value="PL Fehler">

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

                                </DataTrigger>

                            </Style.Triggers>

                        </Style>

                    </syncfusion:GridTextColumn.CellStyle>

Many thanks in advanced

Hi Tom, 

 

Based on the provided details we have created the sample and checked the reported issue “TargetType GridCell does not match Element of Type GridCell”.  . It is working fine as expected. Please find the tested sample from attachment. However we are in need of some more details. Please provide the following details. 

 

1. Syncfusion version you are using in your end.
2. List of all the Syncfusion assemblies referred in your application
3. Entire Xaml file include namespace section.

 

Sample Link : https://www.syncfusion.com/downloads/support/forum/172659/ze/CELLST~1-373009273 

 

Please have a look at this sample and let us know if we have missed any customization done in your application. Otherwise try to reproduce the reported issue in this sample and revert to us with the modified sample and steps to replicate the issue. It will be more helpful for us to find the exact cause for the issue and to provide a prompt solution.

Hi Tom,  

We have suspect that you are getting this issue due to the ambiguity in the GridCell and it can be resolved by adding the separate namespace for the DataGrid as shown in below code snippet. 

<Window 

    x:Class="SfDataGridDemo.Chromeless" 

    xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation

Many thanks !!

Changing this: 

<Style TargetType="syncfusion:GridCell"> 

also to:

<Style TargetType="grid:GridCell"> 

does the trick.

All running fine now.

I have exactly the same problem! The suggested solution did not work for me. Some SyncFusion grids work and others give this error,  Ihave so far not been able to figure out why!
