Question

我要求我需要在使用itextsharp生成的pdf文档上显示复选框。但是，由于itextsharp不支持html输入标记，因此复选框没有出现在我的页面上。我使用asp.net checkboxlist控件，我正在考虑添加背景图像以显示复选框已选中或未选中，但由于某种原因，我无法让它显示仍然。这是我的代码：

 Protected Sub Checkboxlist1_DataBound(sender As Object, e As EventArgs) Handles Checkboxlist1.DataBound
    If test <> "" Then
        Dim checklist As List(Of String) = ReturnListofStringClass.ReturnChecklistListOfString(test)

        For i = 0 To Checkboxlist1.Items.Count - 1
            For Each id As String In checklist
                If Checkboxlist1.Items(i).Value = id Then
                    Checkboxlist1.Items(i).Selected = True
                    Checkboxlist1.Items(i).Attributes("style") = "background: url(http://renegadeox.com/img/on.png) no-repeat red; height:300px; color: blue; font-size:20px;"
                End If
            Next
        Next
    End If
End Sub

应用了背景颜色，但未应用图像。谢谢你的帮助。

也许这会有所帮助。

Protected Sub Checkboxlist1_DataBound(sender As Object, e As EventArgs) Handles Checkboxlist1.DataBound
If test <> "" Then
    Dim checklist As List(Of String) = ReturnListofStringClass.ReturnChecklistListOfString(test)

    For i = 0 To Checkboxlist1.Items.Count - 1
        For Each id As String In checklist
            If Checkboxlist1.Items(i).Value = id Then
                Dim t AS string= Checkboxlist1.Items(i).Text
 Checkboxlist1.Items(i).Text = "<img src='http://renegadeox.com/img/on.png' style='width:10px; height:10px;' alt='' title='' />" & "  " & t

            End If
        Next
    Next
End If
End Sub
