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

C#

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

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

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

ASP.NET

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

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

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

Search google using "Repeater in ASP.NET". Open whatever link you like and see the code there. Compare it with yours. You will find where the problem is.

Use backslash before double quotes and it will work properly:

C#

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

I traied but it didnt work, thanks

My solution is:
file.aspx

ASP.NET

<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

C#

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

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

    return myView;
}
