Specifying new datasource for GridGroupingControl

[Lance Koh]

i will give a brief description on my scenario. i have a dataset, containing 2 datatables. there is a relation binding the 2 tables. the gridgroupingcontrol.datasource is assigned to the dataset. i was able to get the view i want during the first datasource specification. however, when i assign the control to another dataset, i was given the error message saying that the relationship contain error.

i figured that the error could be caused by the control attempting to draw the previous dataset when a new dataset is assigned to it. thus the relation failed. i was wondering how should i get around this situation.

thanks and regards.

You can try resetting the relations. You could also reset the DataMember.

this.gridGroupingControl1.TableDescriptor.ResetRelations();
this.gridGroupingControl1.DataSource = newDataSource;
this.gridGroupingControl1.DataMember = ""; //or whatever else is appropriate

i tried, but nope, it did not work. and i am still facing the same problem...

Instead of ResetRelations, try

this.gridGroupingControl1.TableDescriptor.Relations.Clear();

This seems to work in this sample. GGC_NOParentHreader_5854.zip
