repeater control last row

[Guoqi Zheng]

Sir,

According to our design, very often, I need to have a different html code
for the last row of our repeater control. I can not put those code
difference into footer because those code has to be in the last data row.

How can I edit the last data row of a repeater control??

Create your own repeater control, inheriting
System.Web.UI.WebControls.Repeater and then implement your ITemplate. In
the ITemplate, you can add code to respond to whatever conditions dictate
the HTML code and provide the right output.

Here's a link for a simple custom repeater that will give you a place to
start:

Hi Guoqi,

In the Page object's PreRender event you already know how many items there
are in the repeater. Therefore, you can get a reference to the last item and
do whatever needs to be done with it. Here's a snippet, full source below:

Private Sub Page_PreRender _
(ByVal sender As Object, _
ByVal e As System.EventArgs) _
Handles MyBase.PreRender
Dim itm As RepeaterItem
itm = Repeater1.Items(Repeater1.Items.Count - 1)
Dim lblNotice As New Label
lblNotice.Text = "Last>>>"
itm.Controls.AddAt(0, lblNotice)
End Sub

Does this help?

Repeater1.DataMember = "StringValue"
Repeater1.DataBind()

End Sub

Private Sub Page_PreRender _
(ByVal sender As Object, _
ByVal e As System.EventArgs) _
Handles MyBase.PreRender
Dim itm As RepeaterItem
itm = Repeater1.Items(Repeater1.Items.Count - 1)
Dim lblNotice As New Label
lblNotice.Text = "Last>>>"
itm.Controls.AddAt(0, lblNotice)
End Sub

Function CreateDataSource() As DataTable
Dim dt As New DataTable
Dim dr As DataRow
dt.Columns.Add(New DataColumn _
("IntegerValue", GetType(Int32)))
dt.Columns.Add(New DataColumn _
("StringValue", GetType(String)))
dt.Columns.Add(New DataColumn _
("CurrencyValue", GetType(Double)))
dt.Columns.Add(New DataColumn _
("Boolean", GetType(Boolean)))
Dim i As Integer
For i = 0 To 8
dr = dt.NewRow()
dr(0) = i
dr(1) = "Item " + i.ToString()
dr(2) = 1.23 * (i + 1)
dr(3) = (i = 4)
dt.Rows.Add(dr)
Next i
Return dt
End Function 'CreateDataSource
