AjaxControlToolkit Accordion 和数据绑定

发布于 2024-08-09 12:02:35 字数 894 浏览 2 评论 0原文

我正在使用手风琴的 HeaderTemplate 和 ContentTemplate 控制并将其绑定到数据表。由于某种原因它没有显示任何数据。如果我将数据表绑定到数据列表，它的工作原理如下预计，这是一个已知问题还是我完全在做某事错误的。我在后面的代码中绑定了手风琴控件，如果这样的话有什么区别。这是代码：

<cc1:Accordion ID="databoundaccordion" runat="server" AutoSize="None"  
HeaderCssClass="articleHeader" HeaderSelectedCssClass="articleHeaderSelected" 
ContentCssClass="articleBody" FadeTransitions="true" 
SuppressHeaderPostbacks="true" RequireOpenedPane="true" 
TransitionDuration="250" FramesPerSecond="40">
<HeaderTemplate>
    <%# DataBinder.Eval(Container.DataItem, "name")%>
</HeaderTemplate>
<ContentTemplate>
    <p>Content goes here</p>
    <a href="Articles.aspx">Go</a>
</ContentTemplate>

并在后面的 C# 代码中：

databoundaccordion.DataSource = presenter.getDataTable();
databoundaccordion.DataBind();

I'm using the HeaderTemplate and the ContentTemplate of the Accordion
control and binding it to a datatable. For some reason it doesn't
display any data. If I bind the datatable to a datalist it works as
ecpected, is this a known issue or am i doing something completely
wrong. I'm binding the accordion control in the code behind if this
makes any difference. Here is the code:

<cc1:Accordion ID="databoundaccordion" runat="server" AutoSize="None"  
HeaderCssClass="articleHeader" HeaderSelectedCssClass="articleHeaderSelected" 
ContentCssClass="articleBody" FadeTransitions="true" 
SuppressHeaderPostbacks="true" RequireOpenedPane="true" 
TransitionDuration="250" FramesPerSecond="40">
<HeaderTemplate>
    <%# DataBinder.Eval(Container.DataItem, "name")%>
</HeaderTemplate>
<ContentTemplate>
    <p>Content goes here</p>
    <a href="Articles.aspx">Go</a>
</ContentTemplate>

and in the c# code behind:

databoundaccordion.DataSource = presenter.getDataTable();
databoundaccordion.DataBind();

将 Accordion 绑定到 DataTable 对象时会遇到困难。
相反，通过将其转换为 DataTableReader 来执行以下操作，它应该可以正常工作：

databoundaccordion.DataSource
                    = new System.Data.DataTableReader(presenter.getDataTable());
databoundaccordion.DataBind();

这是带有示例数据的另一个示例：

DataTable dt = new DataTable();
dt.Columns.Add("HeaderText");
dt.Columns.Add("ContentText");

dt.Rows.Add(new object[] { "Heading 1", "Content 1" });
dt.Rows.Add(new object[] { "Heading 2", "Content 2" });

databoundaccordion.DataSource = new System.Data.DataTableReader(dt);
databoundaccordion.DataBind();

You will have difficulties binding an Accordion to a DataTable object.
Instead, do the following by converting it into a DataTableReader and it should work just fine:

databoundaccordion.DataSource
                    = new System.Data.DataTableReader(presenter.getDataTable());
databoundaccordion.DataBind();

Here's another example with sample data:

DataTable dt = new DataTable();
dt.Columns.Add("HeaderText");
dt.Columns.Add("ContentText");

dt.Rows.Add(new object[] { "Heading 1", "Content 1" });
dt.Rows.Add(new object[] { "Heading 2", "Content 2" });

databoundaccordion.DataSource = new System.Data.DataTableReader(dt);
databoundaccordion.DataBind();
