My TreeView controls is rendering CheckBoxes on Leaf nodes. I want to bind to those nodes the ID of the underlying data item. I am not sure I can do this declaratively or if I need to hook up to the TreeNodeDataBound event. If the latter, how would I go about achieving this?

I have a class Person with three properties, ID, Name, Registered. I have the following array of this class
Person1 (ID=A00 ,Name=Andy )
Person2 (ID=A01 ,Name=John )
Person3 (ID=A02 ,Name=Lina )
Person4 (ID=B00 ,Name=Rachel )
Person5 (ID=B01 ,Name=Peter )
Person6 (ID=C00 ,Name=Hans )
Person6 (ID=C01 ,Name=Emily )
I need to show this array in a treeview in this way: When the person has ID finished in 00, it is showed how the father node, and the other persons starting with the same letter are the child nodes.
In this case Andy would be the father indented 0, and john and lina would be his childs indented 1.
I need to show this structure in a checkbox treeview and when I select the father checkbox, the child checkbox must be selected too.

View 2 Replies I have a DevExpress WebChart Control that binds to a DataTable. The chart control renders fine from the DataTable until I try to import data from a details view(i think the chart control renders before the detailsview?).
Here is three renderings.
Chart 1. just rendering from the datatable
Chart 2 The sqldatasource gets its para. from the values of two label controls to render the detailsview. The detailsview renders fine
Chart 3, the problem comes in when I try to extract the values from the DetailsView to populate the Chart, I loose the value. I am assuming the the datatable is built before the rendering of the detailsview? Lost at this point.

I have a form in which I have a dropdown list and a list box.
This dropdownlist is populated by a column in thetable . This drop down list may have values ranging from 1 to 5.
This values in the dropdownlist are to be made the caption headings of the list view control.
For insance if there are three values in the dropdown there should be three columns in the list box with the heading as the values of the dropdownlist.for 5 it should be 5.
Also there are two additional columns which would be constant.
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable
With TblBasket
.Columns.Add("BskPrdCd", System.Type.GetType("System.String"))
.Columns.Add("BskPrdDesc", System.Type.GetType("System.String"))
.Columns.Add("BskQty", System.Type.GetType("System.Int16"))
.LoadDataRow(Split("12345,Test product 1,1", ","), True)
.LoadDataRow(Split("122,Test product 2,2", ","), True)
.LoadDataRow(Split("123A,Test product 3,5", ","), True)
.LoadDataRow(Split("44,Test product 4,1", ","), True)
End With
DstBasket.Tables.Add(TblBasket)
With LfnGridView("GdvBasket")
.DataSource = DstBasket
.DataBind()
End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
