nested repeater

[Not Active]

You have not bound the nested Repeater so of course it will not display anything.

<asp:Repeater ID="Repeater3" runat="server" DataSource='<%# ((SiteMapNode)Container.DataItem).ChildNodes %>'>

Why not? See below.

Please clarify what you mean by this. The example was for a nested Sitemap, you will of course need to adjust it to your usage.

I am taking datasource from the dataset which i passed it to the repeater1.I also tried like this:

<asp:Repeater runat="server" id="Repeater1">
<HeaderTemplate>items<br /><br /></HeaderTemplate>
<ItemTemplate>
<b><%# DataBinder.Eval(Container.DataItem, "catagoryname") %></t>
<br><%# DataBinder.Eval(Container.DataItem, "catagorydescription") %>

    <asp:Repeater ID="Repeater3" runat="server" DataSourceID="DataSourceMember">
    
             <ItemTemplate>
             <br>Items: <%# DataBinder.Eval(Container.DataItem,"ItemName")%></t></t></t><%# DataBinder.Eval(Container.DataItem, "Amount") %>
             <br><%# DataBinder.Eval(Container.DataItem, "ItemDescription") %></br>
              </ItemTemplate>
             </asp:Repeater>
             <asp:SqlDataSource ID="DataSourceMember" runat="server" ConnectionString="server=myComp;uid=sa;pwd=sa;database=ItemCat" SelectCommand="SELECT \* FROM items where catID = '<%# DataBinder.Eval(Container.DataItem,"ID") %>'"  \\>

</ItemTemplate>
      <separatortemplate>
         <br />
         <br />
         <br />
       </separatortemplate>
    </asp:Repeater>

erros is : Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: The server tag is not well formed. Source Error: Line 193: </ItemTemplate> Line 194: </asp:Repeater> Line 195: <asp:SqlDataSource ID="DataSourceMember" runat="server" ConnectionString="server=myComp;uid=sa;pwd=sa;database=ItemCat" SelectCommand="SELECT * FROM items [ACN] Where catID = '<%# DataBinder.Eval(Container.DataItem,"ID") %>'" \> Line 196:

Now we finally get to the issue, "Parser Error Message: The server tag is not well formed". You could have saved a few steps and gave this information at the beginning. This is not the best way to accomplish this. You understand you are going to create a new SqlDatasource for each item in the parent list? Handle the ItemDataBound event of the parent repeater and assign the datasource, perferably from a cached source.

itemDataBound event is like this right:

    void Repeater1\_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        RepeaterItem item = e.Item;
        if ((item.ItemType == ListItemType.Item) ||
            (item.ItemType == ListItemType.AlternatingItem))
        {

            Repeater3 = e.Item.FindControl("Repeater3");
            DataRowView drv = (DataRowView)item.DataItem;
            Repeater3.DataSource = drv.CreateChildView("category\_item");
            Repeater3.DataBind();
        }
    }

but if i do like this, it give error as below: Repeater3 doesn't exits.. while ascx.cs code is

<asp:Repeater runat="server" id="Repeater1">
<HeaderTemplate>items<br /><br /></HeaderTemplate>
<ItemTemplate>
<b><%# DataBinder.Eval(Container.DataItem, "catagoryname") %></t>
<br><%# DataBinder.Eval(Container.DataItem, "catagorydescription") %>

    <asp:Repeater ID="Repeater3" runat="server">
    
             <ItemTemplate>
             <br>Items: <%# DataBinder.Eval(Container.DataItem,"ItemName")%></t></t></t><%# DataBinder.Eval(Container.DataItem, "Amount") %>
             <br><%# DataBinder.Eval(Container.DataItem, "ItemDescription") %></br>
              </ItemTemplate>
             </asp:Repeater>
             

</ItemTemplate>
      <separatortemplate>
         <br />
         <br />
         <br />
       </separatortemplate>
    </asp:Repeater>

Repeater3 = e.Item.FindControl("Repeater3");

Of course it doesn't exist, what type is Repeater3? All you have is a name. You also understand FindControl needs to be cast to something useful?

yes. i did like this:

Repeater3 =(Repeater) e.Item.FindControl("Repeater3");

now i have another error shown. The relation is not parented to the table to which this DataView points. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: The relation is not parented to the table to which this DataView points. Source Error: Line 120: Repeater2 = (Repeater)e.Item.FindControl("Repeater2"); Line 121: DataRowView drv = (DataRowView)item.DataItem; Line 122: Repeater2.DataSource = drv.CreateChildView("CategoryToItem"); Line 123: Repeater2.DataBind(); Line 124: }

Sorry, I couldn't get that. Can you explain that please ? I even included below code:

SqlCommand objCmd = new SqlCommand(query, cnx);
SqlDataAdapter objDA = new SqlDataAdapter(objCmd);
DataSet ds = new DataSet();
objDA.Fill(ds);
Repeater1.DataSource = ds;
Repeater1.DataBind();

        DataColumn c1 = ds.Tables\["category"\].Columns\["ID"\];
        DataColumn c2 = ds.Tables\["Items"\].Columns\["CatID"\];
        dRel = new DataRelation("CategoryToItem", c1, c2);
        ds.Relations.Add(dRel);
