Binding Runtime properties to SfDataGrid

[Veeresh]

Hi All,

I have WPF(MVVM) application where i populate data from a table and bind it to SfDataGrid. Now the requirement is that during design time i don't know the columns in the DataGrid. I am using Columns to add various columns to SfDataGrid. Now i have to bind values to those columns. As i don't know columns during design time, i add properties to my model using ICustomTypeProvider. This interface allows me to add properties to my model during runtime. After i add properties to my Model, i tried to bind ObservableCollection of my Model to SfDataGrid but i am getting following error.

 Error: Specified method not supported.

Code Sample:

Adding dynamic property to Model:

DataFormGrid.AddProperty(currentValue.Name, typeof(string));

Adding Dynamic columns to SfDataGrid:

GridColumns.Add(new GridTextColumn() { HeaderText = item.Name, MappingName = item.Name });

My question is does it support binding column to dynamic property?

Hi Veeresh,

Thank you for contacting Syncfusion support.

We could not proceed with the reported exception issue based on the given stack trace when the data and columns are added dynamically. Could you please share more details with the sample or code snippet for the derived class of ICustomTypeProvider and column generation, thereby we could analyze further and update you with the appropriate details at the earliest.

Regards,
