Host a PropertyEditor in a DataGridView cell

[tonitpp]

Hi all,

I am using Net Measurement Studio in C# and I would like to know how can I host a PropertyEditor (for example, LineStyle as property for a plot object) in a DataGridView cell. Is it possible? how can I achieve this?

Thanks.

Hi,

I have hosted a PropertyEditor into a datagridviewcolumn as a custom cell following the below approach:

http://msdn.microsoft.com/en-us/library/7tas5c80.aspx

but when my datagridview is loaded (columns/rows created), cell of type PropertyEditor are not visible until you do double-click. Also after double click below error is generated inmediatelly (in this case I have a propertyeditor whose source is object=ScatterPlot, propertyName=LineStep.

Error Details:

The type initializer for 'NationalInstruments.UI.Internal.WaveformPlotElement' threw an exception.The type initializer for 'NationalInstruments.PrecisionTimeSpan' threw an exception.Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

I am trying to solve two issues:

1) Why custom PropertyEditor cell is not visible?

2) Why after doubleclick on cell it crashes with the above message?

Thanks.

By adding useLegacyV2RuntimeActivationPolicy="true" to app.config file in the project solved it.

<startup useLegacyV2RuntimeActivationPolicy="true">

            <supportedRuntime version="v4.0"/>

</startup>
