ASPxDataView - How to create the control and assign the ItemTemplate at runtime

[DX Support team: Posted by Guiem Julià]
Hello Marion,

thank you for your answer. I forgot to give you more info in the ticket. I didn't add the ASPxDataView to a form because I add it to an ASPxPageControl. So my code is:

int page= 0;

XPCollection<Sector> sectores = new XPCollection<Sector>(sesion);

foreach (Sector sector in sectores)

{

ASPxPageControlSectores.TabPages.Add(sector.Nombre, sector.Oid.ToString());

ASPxDataView dv = new ASPxDataView();

ASPxPageControlSectores.TabPages[pagina].Controls.Add(dv);

dv.ItemTemplate = new MyItemTemplate();

dv.DataSource = sQueries.DameQuejasSector(sesion, sector.Oid);

dv.DataBind();

pagina++;

}

So I have a loop for a XPCollection, for each item I create a new TabPages, a new DataView and I add the DataView to the new TabPages. If I do like this I have the problem of TemplateControl=null.

Thank you

If you add a control into a container, it is necessary to create a container hierarchy first. For example:

for (int i = 0; i < 5; i++) {
    ASPxPageControlSectores.TabPages.Add("Nombre" + i, "Oid" + i);
}
ASPxPageControlSectores.DataBind();

I have attached a sample project that illustrates this solution. Please check it.

Thank you Marion. ASPxPageControlSectores.DataBind(); solves the problem. I didn't know I must databind the aspxpagecontrol too.

Best regards,
