数据集中的DataSet问题与设置DataSource有关 [英] DataSet in Dataset problem with set DataSource

问题描述

我在另一个数据集的ds列中有samo DataSet。

Hi, i have samo DataSet in "ds" column of another dataset.

for(int i...)
{
    DataSet data=....
    ds.Tables[0].Rows[i]["Datas"] = data;
}

cList.DataSource = ds;
cList.DataBind();

在aspx文件中我有转发器和DropDownList（填充下拉列表，数据集在其他数据集中）

In aspx file i have repeater and DropDownList (fill dropdownlist with dataset which is in other dataset)

<asp:Repeater ID="cList" runat="server">
<asp:DropDownList runat="server" ID="selectFProd" DataSource="<%# Eval("Datas") %>" DataTextField="Col1" DataValueField="Col2ID"></asp:DropDownList>
</asp:Repeater>

当我运行我的asp.net应用程序时，我得到了这个错误

When i run my asp.net application, i get this error

Parser Error Message: The server tag is not well formed.

for line，where is is DropDownList。我做错了什么？谢谢

for line, where is the DropDownList. What im doing wrong? Thanks

推荐答案

在双引号之前使用反斜杠它会正常工作：

Use backslash before double quotes and it will work properly:

<asp:DropDownList runat="server" ID="selectFProd" DataSource="<%# Eval(\"Datas\") %>"

我的解决方案是：

file.aspx

I traied but it didnt work, thanks

My solution is:
file.aspx

<asp:dropdownlist runat="server" id="sFP" datasource="<%# fillDataList((string)DataBinder.Eval(Container.DataItem, "C_ID")) %>" datatextfield="Title" xmlns:asp="#unknown"></asp:dropdownlist>

file.aspx.cs

file.aspx.cs

public DataView fillDataList(string id)
{
    DataSet data = DB.GetData("SELECT * FROM … WHERE FK =" + id + ")", false);

    DataView myView = data.Tables[0].DefaultView;

    return myView;
}
