Hello

I have a WHDG binds to flat dataset. I make the relations via WHDS. If I set InitialDataBindDepth property to 1 there is no problem it can bind the child row without problems. But I want to bind the data with LoadOnDemand method. So if I set the InitialDataBindDepth to 0, it can see which parent record has child but it cannot bind data.

Here is my code (C#)

dsMessages = Messages.MesajGetir(RezervasyonRef, 3, 1);
dsKullanici = Messages.KisiGetir(RezervasyonRef, 0, 1);
dtMessages = dsMessages.Tables[0];
dtMessages.TableName = "tableMesaj";
dtKullanici = dsKullanici.Tables[0];
dtKullanici.TableName = "tableKisi";

Infragistics.Web.UI.DataSourceControls.DataView dvKisi = new Infragistics.Web.UI.DataSourceControls.DataView();

dvKisi.ID = "vBaslik";
dvKisi.DataMember = "tableKisi";
dvKisi.DataSource = dtKullanici;

#region comment dvMesaj
Infragistics.Web.UI.DataSourceControls.DataView dvMesaj = new Infragistics.Web.UI.DataSourceControls.DataView();

dvMesaj.ID = "vMesaj";
dvMesaj.DataMember = "tableMesaj";

dvMesaj.DataSource = dtMessages;

whdsShowMessages.DataRelations.Clear();
whdsShowMessages.DataViews.Clear();
whgridShowMessages.Rows.Clear();

whdsShowMessages.DataViews.Add(dvKisi);
whdsShowMessages.DataViews.Add(dvMesaj);

Infragistics.Web.UI.DataSourceControls.DataRelation drel =
new Infragistics.Web.UI.DataSourceControls.DataRelation("vBaslik", "ID", "vMesaj", "ID");
whdsShowMessages.DataRelations.Add(drel);
#endregion

whgridShowMessages.DataSource = whdsShowMessages;

whgridShowMessages.DataBind();

and here is the (.aspx)
