Data Poulation problem while Scrolling... virtualization is on

[Sharada]

Hi

 I am using TreeListView. 
 I am adding columns dynamically at runtime

GridViewDataColumn

 

 

column;

 

 

 

for (int icnt = 1; icnt < ts.Days; icnt++)

 

{

column =

 

new GridViewDataColumn();

 

column.UniqueName =

 

"key" + icnt.ToString();

 

column.IsReadOnly =

 

false;

 

RadTreeListView1.Columns.Add(column);

}


I am populating the cell data in RadTreeListView1_RowLoaded event.

 

var

 

 

row = e.Row as TreeListViewRow;

 

 

 

foreach (GridViewCell cell in row.Cells)

 

{

 

 

if (cell.IsLoaded)

 

{

 

 

DateTime dates;

 

 

 

if (DateTime.TryParse(cell.Column.Header.ToString(), out dates))

 

{

 

 

string filter = "dates = '#" + dates.ToShortDateString().ToString() + "#'";

 

 

 

DataRow[] dr = lobjdt.Select(filter);

 

 

 

if (dr != null && dr.Length > 0)

 

{

cell.Content = dr[0][

 

"hours"].ToString();

 

}

}

}

}

I am facing one problem here.
Data in dynamic columns will populate only when columns are visible , data wont get populate if columns are not
visible.

I guess there is a problem with virtulisation while horizontal scrolling..

Please suggest.

Hello,

 RowLoaded event will not be raised when scrolling horizontally. If you want to use such approach you can turn off horizontal virtualization - EnableColumnVirtualization="False".

Kind regards,

Hi Telerik Team,

 Thanks for your previous reply.

 I am facing problem while srcolling with large data.

 For Columns making  EnableColumnVirtualization="False" ok but for Rows I want to make  EnableRowVirtualization="True".

 Scrolling is working fine while scrolling down by expanding Rows but when I want to scroll up , window gets hang and all Rows will collapse.

 Please suggest if I am missing anything here.
