Hi everybody!

Does anybody know how to obtain the value of elements in a DataList?

I know how to obtain the index of the actual element, but not its text.

Thanks

You can use the SelectedItem property to access the selected item. Then you can access the Data Item property (which is a System.Data object, such as a DataRowView), or if you are using a control as a template in the DataList, you can use the Controls property to access the control in the column.

Hope this helps.

Hi bmains!

I found something like this, but I don't use templates, and I don't know how to use the Data Item property. Could you be more specific, please?

Sorry... I really use templates.

I have a DataList with the next templates:

                <ItemTemplate>
                    <asp:LinkButton id="id_producto" runat="server">
                        <%#DataBinder.Eval(Container.DataItem, "id_producto")%>
                    </asp:LinkButton>
                    <asp:Label id="Label2" runat="server" Width="30px"></asp:Label>
                    <asp:LinkButton id="LinkButton2" runat="server">
                        <%#DataBinder.Eval(Container.DataItem, "nombre")%>
                    </asp:LinkButton>
                </ItemTemplate>

If I try something like this:

            if (e.Item.FindControl("id_producto") != null )
                lblMensaje.Text = e.Item.FindControl("id_producto").ToString();

I only obtain the text "System.Web.UI.WebControls.LinkButton" (sic).

Try:

if (e.Item.FindControl("id_producto") != null )
                lblMensaje.Text = ((LinkButton) e.Item.FindControl("id_producto")).Text;

You have to convert the control to a LinkButton to access the text property.

I hope my C# syntax is correct; I'm a VB developer and only dabbled with C# a little.

Hi bmanis,

You're right. And it really works with a source like this:

<asp:LinkButton id="LinkButton1" runat="server">test</asp:LinkButton>

but NOT if you're working with databinders:

<asp:LinkButton id="id_producto" runat="server">
   <%#DataBinder.Eval(Container.DataItem, "id_producto")%>
</asp:LinkButton>

Buuufff... I don't know nothing more to try. :(

Maybe you should try accessing the DataItem property. I'm not really familiar with it, except that you can convert it to a DataRow or DataRowView, then access the source.

Hi,

I solved days ago, in the way:

string sCodProducto = dsProductos.Tables[0].DefaultView[e.Item.ItemIndex].Row["id_producto"].ToString();

As you could see, I used the DataSet and DefaultView, both with DataListCommandEventArgs.

Thanks Anyway
