Relation does not show

[Steffen]

Hello,

I try to create a relation between the MasterTemplate and a ChildTemplate.

The DataSources for the templates have to be filled manually, due they come from different sources (REST and .Net-Remoting).

After fill in the data, I create a relation between them

var relation = new GridViewRelation(_StockGridView.MasterTemplate);

relation.ChildTemplate = _PartsTemplate;

relation.RelationName = "PartToArticleCode";

relation.ParentColumnNames.Add("ID");

relation.ChildColumnNames.Add("ArticleCodeID");

this._StockGridView.Relations.Add(relation);

Unfortunatly... this does not work (anymore!). It worked the first time I created the form etc., but after I've added a control to a container to the form (not to the grid), the gridview refuses to show the hierarchy anymore.

Maybe someone got a clue... I haven't :(

Regards,

Hi Steffen,

Thank you for writing.

Setting the hierarchical grid in unbound mode is quite similar to that for the bound mode with only difference is setting the unbound mode itself. First of all you need to create and the columns you need. After that set up the relation and finally load the data.

Read the documentation article about "Unbound Mode" and more specific "Hierarchical Grid in Unbound mode" section: http://www.telerik.com/help/winforms/gridview-populating-with-data-unbound-mode.html.

If you continue experiencing issues, please get back to me with a sample application demonstrating the undesired application and I will look into it for you.

I hope that you find this information useful. If you have any other questions, feel free to write back.
