Please help again. I have a
<asp:datalist id="ProdList" runat="server" DataKeyField="productTypeID" OnItemCommand="ProdList_ItemCommand">
<ItemTemplate>
<asp:Label id="lblproductTypeID" runat="server">
<%# DataBinder.Eval(Container.DataItem, "productTypeID") %>
</asp:Label>
<asp:Button id="Button1" runat="server" CssClass="ProductListButton" ToolTip="Show/Hide Details" Width="65px" Text="Details" CommandName="expand"></asp:Button>


and when I run this the label does contain the correct productTypeID.
However in the C# code behind page when the button is clicked I try to get the contents of the label and fail.
public void ProdList_ItemCommand(object source, System.Web.UI.WebControls.DataListCommandEventArgs e) {
//get the list index of the product selected
ProdList.SelectedIndex = e.Item.ItemIndex;
// using that index, get a handle on the Label
Label ptypeID = (Label)ProdList.Items[ProdList.SelectedIndex].FindControl("lblProductTypeID");

......
int productTypeID1 = Convert.ToInt32(ptypeID.Text);

ptypeID.Text = "" and
productTypeID1 ""

First, Why doesn't this work?
Second, could I somehow get the selected index of the DataKeyField more easily than using a label?

Thanks in advance for your help.

Don't you just wish that C# wasn't case sensitive, every now and then??? ;)

<asp:Label id="lblproductTypeID" runat="server">

Vs

// using that index, get a handle on the Label
Label ptypeID = (Label)ProdList.Items[ProdList.SelectedIndex].FindControl("lblProductTypeID");

Does this help?

Arrrrrrgh!!! (Sound of chewing nails)

But - - now
<asp:Label id="lblProductTypeID" runat="server">
<%# DataBinder.Eval(Container.DataItem, "productTypeID") %>
</asp:Label>

and I get the same results:
ptypeID.Text = "" and
productTypeID1 ""

and
int productTypeID1 = Convert.ToInt32(ptypeID.Text);
produces an error "not in correct format"


Sandy

I found the problem. This syntax must be used:
<asp:Label id=lblProductTypeID runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "productTypeID") %>'>
</asp:Label>

and then it works.

On the second question, is there indeed a way to get the DataList DataKeyField with an ItemCopmmand?


Sandy

Oh, yes there is. You can retrieve the DataKey from the List control using its DataKeys collection and the ItemIndex for the "current" item, like this:

int selectedIndex = e.Item.ItemIndex;
int dataKey = (int) ProdList.DataKeys[selectedIndex];

Cheers,

Imar
