Hi,

Do you think I can use OnRowDragStarted event to let the dragclue icon change when I hover an area where the clue may be dropped like this demo:

http://demos.telerik.com/aspnet-ajax/treelist/examples/itemsdragdrop/defaultcs.aspx

I tried but I see that OnRowDragStarted has no get_destinationHtmlElement()

Thanks,
Marc

bind datasource to nested radgrid codebehind

I'm trying to follow along with this demo
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx

However I want to bind the datasource of the first nested radgrid on the code behind.

I thought it might be something like this but is it more complicated than this?
RadGrid1.MasterTableView.DetailTables.radGrid2.DataSource = myDatasource;

Also another question, when I bind to this nested grid (radGrid2), I send all records and the following code will filter or do I need to grab the ID on a method call within the radGrid1? If so please direct me to how to do accomplish this?
<ParentTableRelation>
<telerik:GridRelationFields DetailKeyField="referenceID" MasterKeyField="referenceID"></telerik:GridRelationFields>
</ParentTableRelation>

overview,
radGrid1 shows all records, use the dropdown and show records in the radGrid2 that pertain to that ID of radGrid1.

I foudn the following but get an error : on this line - (GridTableView)item.ChildItem.NestedTableViews[0]

Index was outside the bounds of the array.

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

using (var db = new E3TDataContext())

{

citationItems = db.Citations.ToList();

//RadGrid1.MasterTableView.DetailTables.radGrid2.DataSource = myDatasource;

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

GridTableView nestedView = (GridTableView)item.ChildItem.NestedTableViews[0];

if (item["parentrowColumnUniqueName"].Text == "Text")

nestedView.DataSource = citationItems;

else if (item["parentrowColumnUniqueName"].Text != "Text")

nestedView.DataSource = citationItems;

}

Thanks

Dynamic adding data to TreeList

Can I dynamic adding data to TreeList instead of using dataSource? it just like DataTable, we can add column and row by using behind code programming:

Dim data As New DataTable
data.Columns.Add("textHeader", GetType(String))
data.Columns.Add("valueHeader", GetType(String))
data.Rows.Add("text1", "value1")
data.Rows.Add("text2", "value2")

[Solved] Number of child nodes

I need to get the number of child nodes of a treelist node. 

But the instruction item.ChildItems.Count is always zero.

What I am doing wrong.

protected void RadTreeList1_ItemDataBound(object sender, TreeListItemDataBoundEventArgs e)

{

if (e.Item is TreeListDataItem)

{

TreeListDataItem item = e.Item as TreeListDataItem;

int numberOfChilds = item.ChildItems.Count;

....
