Hi all,

I have a nestedview on a rad grid. I am trying to follow the examples provided but I cannot make it work properly. In the onItemCommand event I am binding a formview which is in the nestedview. When I expand the first row, I can see everything properly, however all rows after that show nothing. I have made sure that I am properly binding the formview and that the datasource has valid data.

Please review the code and help.

protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)  
        {  
            try 
            {  
                RadGrid1.DataSource = myWorkorderController.getAllWorkorders("Closed");  
            }  
            catch (Exception ex)  
            {  
                throw ex;  
            }  
        }  
 
        protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)  
        {  
            if (e.CommandName == RadGrid.ExpandCollapseCommandName)  
            {  
                if (!e.Item.Expanded)  
                {  
                    FormView oFormView = (FormView)RadGrid1.MasterTableView.Items[0].ChildItem.FindControl("FormView1");  
                    ACareFlangeWOHistoryByWOID_inType oWOHistInfo = new ACareFlangeWOHistoryByWOID_inType();  
                    oWOHistInfo.WOID = e.Item.OwnerTableView.Items[e.Item.ItemIndex]["WONUM"].Text;  
                    oFormView.DataSource = myWorkorderController.getAllWorkorderHistory(oWOHistInfo);  
                    oFormView.DataBind();  
                    ((GridDataItem)e.Item).ChildItem.FindControl("NestedViewPanel").Visible =  
                   !e.Item.Expanded;  
                }  
            }  
        }  
 
        protected void RadGrid1_PreRender(object sender, EventArgs e)  
        {  
            if (!Page.IsPostBack)  
            {  
                RadGrid1.MasterTableView.Items[0].Expanded = true;  
                RadGrid1.MasterTableView.Items[0].ChildItem.FindControl("NestedViewPanel").Visible = true;  
            }  
        }  
 
        protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)  
        {  
            if (e.Item is GridNestedViewItem)  
            {  
                //e.Item.FindControl("InnerContainer").Visible = ((GridNestedViewItem)e.Item).Parent.Expanded;

Hello Ali Kitabi,

The reason for this is that in your code you are accessing only the first rows Nested formview. You can rewrite your code as shown below and check if it helps:
c#:
protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)   
   {   
     if(e.CommandName == RadGrid.ExpandCollapseCommandName)     
        {     
          if(!e.Item.Expanded)     
             {     
               FormView oFormView = (FormView)(e.Item as GridDataItem).ChildItem.FindControl("FormView1"); // Replace   
               ACareFlangeWOHistoryByWOID_inType oWOHistInfo = new ACareFlangeWOHistoryByWOID_inType();     
               oWOHistInfo.WOID = e.Item.OwnerTableView.Items[e.Item.ItemIndex]["WONUM"].Text;     
               oFormView.DataSourceID = myWorkorderController.getAllWorkorderHistory(oWOHistInfo);     
               oFormView.DataBind();     
               ((GridDataItem)e.Item).ChildItem.FindControl("NestedViewPanel").Visible =  !e.Item.Expanded;     
                }     
            }    
     }  

Thanks
Princy.
