Hi Grzegorz,
Thanks for contacting Syncfusion support.
We have analyzed your requirement. In the sample data set bound to the GridGroupingControl, it is not compatible with GanttControl, so that need to parse the data set and convert it into the generic collection by using following steps.
Step 1:Need to create a template class with properties to hold the each column values of DataSet.
Public class Model
{
// First column value holder
Public DataType ColumnName1{ get; set; }
Public DataType ColumnName2{ get; set; }
.
.
.
Public DataType ColumnNameN{ get; set; }
}
Step 2:
Generate a record for each row in the Dataset and add it into the collection.
ObservableCollcetion<Model> collection = new ObservableCollcetion<Model>();
Collection.Add(new Model()
{
ColumnName1 = GridGroupingControl.DataSet.Column1.
ColumnName2 = GridGroupingControl.DataSet.Column2.
});
Step 3:Bind the collection to the GanttControl ItemsSource property.
Refer to the following code sample for further reference.
