Essential Grid and Reflection

[Administrator]

Hello. Does someone know how can I access to Essential Grid's and Columns' properties via PropertyInfo.GetValue, SetValue.
I have following code:
PropertyInfo oProperty=null;
oProperty=EssColumn.StyleInfo.GetType().GetProperty("CellAppearance")
if (oProperty.CanRead)
{
object oValue = oProperty.GetValue(EssColumn.StyleInfo,null); - here I get exception "'System.Reflection.TargetInvocationException' occurred in mscorlib.dll"
}
However following works without exception:
oProperty.SetValue(EssColumn.StyleInfo,SomeValue,null);

Thanks to anybody who can help.

Hi Dmitry,

I modified the samples\databound\gdbdmultiheader sample in order to reproduce the problem.

I added

using System.Reflection;

and I added the following lines at the end of Form1_Load:

PropertyInfo pi = this.gridBinder.InternalColumns[0].StyleInfo.GetType().GetProperty("CellAppearance");
object ob = pi.GetValue(this.gridBinder.InternalColumns[0].StyleInfo, null);
Trace.WriteLine(ob);

That seems to work fine.

Can you tell me what you are doing different?

Thanks,
Stefan

The main problem is that I create GrigColumn with System.Activator. In this way I cannot access it via InternalColumns. But this is not critical.
I discovered that when Activator creates new object of GridColumn some fields are undefined, and this causes exception when I try to read such a field. I think this is a problem of .net itself not Syncfusion.

Thank you.
