I have the same issue i.e if i put autogeneratebands=true the parent child relation seems fine but when i do autogeneratebands=false and define band myself i dont see the expand/collapse animation. here is my code.

//aspx//

<

="false"

="0">

="Auto"

/>

>

>

>

/>

>

>

>

>

="MKT_AREA">

//code behind//

igV.InitialDataBindDepth = -1;

DataSet ds = new DataSet();

DataTable dt = LeaseNego.getRegions();

DataTable dtArea = LeaseNego.getOpsArea();

ds.Tables.Add(dt); ds.Tables.Add(dtArea);

DataRelation dRelation = new System.Data.DataRelation("RGN_Relation",dt.Columns["RGN_CDE"],dtArea.Columns["RGN_CDE"]);

ds.Relations.Add(dRelation);

"dt"; igV.Bands[0].DataMember = "dtArea";

igV.DataSource = ds;

igV.DataBind();

Hi,

I got same issue.I fixed that issue Making Autogenaratebands=true and created band manually, I am pasting my ocde below.

apsx.cs

 protected void Page_Load(object sender, EventArgs e)
        {

                   if (!Page.IsPostBack)

Thanks kavitha,

but your solution way is also not working. i tried setting autogeneratedbands = true and manualy added the band but it didnt help it is showing me all the columns just like if i dont make bands manually and only set the autogeneratedbands=true.

Anyoen else if you could help that would really be appreciated.
