PROJECT DESCRIPTION
 I have problems with Rad treeview:
I have a dataset that contains 2 datatables.
First table : Parent_ID , Parent_Text
Second table : Parent_ID, CHild_ID, Child_Text

 

 

DataColumn parentColumn = gl_dsLayerLOBsWIN.Tables["PriceLayerWin"].Columns["Layer"];

 

 

 

DataColumn childColumn = gl_dsLayerLOBsWIN.Tables["PriceLayerLOBWin"].Columns["Layer"];

 

 

 

DataRelation relation = new DataRelation("parent2Child", parentColumn, childColumn);

 

gl_dsLayerLOBsWIN.Tables[

 

"PriceLayerLOBWin"].ParentRelations.Add(relation);

 

radGridView_Layers.DataSource = gl_dsLayerLOBsWIN.Tables[

 

"PriceLayerWin"];

 


radTreeView_Layers.RelationBindings.Add(

 

new RelationBinding("PriceLayerWIN_PriceLayerLOBWIN", gl_dsLayerLOBsWIN));

 

radTreeView_Layers.DataSource = gl_dsLayerLOBsWIN;

 Initially Dataset is empty. When I add a row to Parent datatable and a couple of rows to Child Datatable I see only first level node(s)....  I do not see sublevels.
Could you , please help me with this.
I tried to use Gridview for this purpose also and tried to group it, but I still do not see any data for sublayers .. may be I'm missing something ...

Thank you ,
Victoria.

Hi Victoria,

Thank you for writing.

Please refer to the attached sample application. It contains projects that demonstrate how to bind RadTreeView to a data set with related tables as well as to custom related objects. The projects are in both C# and VB.

A bit off topic, please submit your enquiries in the appropriate forum sections or in the support ticketing system. The Code Library secion is a place for exchanging code samples, sharing knowledge and getting hands-on experience.

Thank you for your understanding.

All the best,
Victor

Hello Victoria F,

Please note that in Q1 2011 we have introduced a major upgrade of RadreeView control, which is now virtualized and fully customizable. Feel free to download the latest release and try it out. For more information on our latest release refer to this blog post.
