Hello,

I want to create a TempalteField in a DetailsView dynamically. I call the
"SetDetailsTemplateFields"-Method on every Postback (Page_OnLoad).

The Problem that occurs is, that on every Postback I get a new row, but the
TemplateField is only created in the last row.

Example:

ID 10

Name Smith

Memo [ ] <- TemplateField

After Postback:

ID 10

Name Smith

Memo

Memo [ ] <- TemplateField

When I try to update the DetailsView I get an ArgumentOutOfRangeException.

How can I make sure, that only one row is created for every TemplateField?

Thanks and regards,

Stefan



Public Class AddTemplateToDetailsView

Implements ITemplate


Private m_ListItemType As ListItemType
Private m_Field As New DetailField



Public Sub New(ByVal _listItemType As ListItemType, ByVal _field As
DetailField)

m_ListItemType = _listItemType
m_Field = _field

End Sub


Public Sub InstantiateIn(ByVal container As System.Web.UI.Control)
Implements System.Web.UI.ITemplate.InstantiateIn

Select Case m_ListItemType

Case ListItemType.Item

Select Case m_Field.ItemType.ToLower()

Case "textbox_multi"

Dim tb As New TextBox
tb.Rows = 5
tb.TextMode = TextBoxMode.MultiLine
tb.Text = "Test"

container.Controls.Add(tb)

Case Else

End Select

Case Else


Throw New Exception("Unknown ListItemType.")

End Select

End Sub



Public Sub SetDetailsTemplateFields(ByRef _dv As
System.Web.UI.WebControls.DetailsView, ByVal _dvdId As String)

Dim oDBSqlClient As New DBSqlClient()
Dim dvFields(0) As DetailField

dvFields = oDBSqlClient.GetDetailViewFields(_dvdId)

Dim counter As Integer = 0

For Each dvField As DetailField In dvFields

If counter <> 0 Then

ReDim Preserve dvFields(counter)

End If


Select Case dvField.Type.ToLower()


Case "template"

Dim tf As TemplateField = New TemplateField()

If Not String.IsNullOrEmpty(dvField.ItemType) Then
tf.ItemTemplate = New
AddTemplateToDetailsView(ListItemType.Item, dvField)
End If
If Not String.IsNullOrEmpty(dvField.EditType) Then
tf.EditItemTemplate = New
AddTemplateToDetailsView(ListItemType.EditItem, dvField)
End If
If Not String.IsNullOrEmpty(dvField.InsertType) Then
tf.InsertItemTemplate = New
AddTemplateToDetailsView(ListItemType.SelectedItem , dvField)

End If

tf.HeaderText = dvField.HeaderText


_dv.Fields.Add(tf)


End Select

counter += 1

Next

End Sub

Hi Walter,

thank you very much for your answer.

The problem is just solved. The fields "id" and "name" are BoundFields. I
now clear the entire DetailsView-Fields and create the bound and
templatefields on every postback. Is there another way to handle this?

I have another question concerning the databinding of the TemplateField. I
use a SqlDataSource. The BoundFields have the DataValue-Property to bind the
Update-/Insert-Parameter to the SqlDataSource. How can I bind a
TemplateField to the SqlDataSource? When I try to update a dataset I allways
get the error-message, that the scalar-variable is not declared.

Thanks and regards,

Stefan
