<EditItemTemplate>

Note on the line below how I set the TEXT of the TextBox txtName to vName…

<asp:TextBox id=txtName runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "vName") %>'></asp:TextBox><BR>>

<asp:Button id="Button1" runat="server" Text="Button"></asp:Button>

<asp:Button id="Button2" runat="server" Text="Button"></asp:Button>

<sp:Button id="Button3" runat="server" Text="Delete" CommandName = "delete"></asp:Button>

</EditItemTemplate>

<ItemTemplate>

<asp:DropDownList id="ddlNames" runat="server" DataSource='<%#GetDropDownDataTable() %>' DataTextField="vName" DataValueField="vName" />

</ItemTemplate>

Here’s the function that loads the DropDownList’s Values…

Function GetDropDownDataTable()

'***********'********** Create A Table ***********************************

Dim dt As New DataTable()

Dim dr As DataRow

dt.Columns.Add(New DataColumn("vAge", GetType(Int32)))

dt.Columns.Add(New DataColumn("vName", GetType(String)))

Dim i As Integer

For i = 0 To 8

dr = dt.NewRow()

dr("vAge") = i

dr("vName") = "My Name " & i.ToString()

dt.Rows.Add(dr)

Next i

'**************************************************************************

Return dt

End Function

This code checks the Dropdown list Selected Item…

Private Sub cmdDDL_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdDDL.Click

Dim i As Integer

Dim DDL As DropDownList

For i = 0 To DataList1.Items.Count - 1

DDL = DataList1.Items(i).FindControl("ddlNames")

Response.Write("DropDownList.text = " & DDL.SelectedItem.ToString)

Next

End Sub

The code below runs when the “Check The Radio Buttons” Command Button is pressed…

Private Sub cmdCheckRadio_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdCheckRadio.Click

Dim i As Integer

Dim R1 As RadioButton

Dim R2 As RadioButton

‘Loop Through all the DataList’s Items,(Items are really just Rows).

For i = 0 To DataList1.Items.Count - 1

R1 = DataList1.Items(i).FindControl("RadioButton1")

R2 = DataList1.Items(i).FindControl("RadioButton2")

If R1.Checked Then

Response.Write("Radio Button 1 Checked At Item " & i & "<br>")

End If

If R2.Checked Then

Response.Write("Radio Button 2 Checked At Item " & i & "<br>")

End If

Next

End Sub

This is how to modify a template cell at runtime…

Private Sub DataGrid1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles DataGrid1.ItemDataBound

      If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
            CType(e.Item.FindControl("TextBox1"), TextBox).Text = Val(e.Item.Cells(1).Text) * 10
      End If

End Sub

How To Format A Date In A DataList…

<asp:TextBox id=txtCheckDate runat="server" Text='<%# format("{0:d}",DataBinder.Eval(Container.DataItem, "Check_Date")) %>'></asp:TextBox>

OR

<asp:TextBox id=txtCheckDate runat="server" Text='<%# MyDateFormat(DataBinder.Eval(Container.DataItem, "Check_Date")) %>'>

Public Function MyDateFormat(ByVal vO As Object)

If IsDBNull(vO) Then

Return (" ")

Else

Return (Format("{0:d}", vO))

End If

End Function
