Hello all!!

I have taken a label for showing message to the user.
I have a dropdown-list. If the Item Count of dropdown list is 0, i want to show the label to the user else not. I did the following but it's not working as expected. Can you please tell me what's wrong with this code and what should i do to get the expected result ??

XML

<asp:Label ID="lblMessage" runat="server" Text="Currently there are no products in this category" Visible='<%# bool.Parse((ddlProducts.Items.Count==0).ToString())%>' Font-Bold="true" Font-Italic="true" Font-Names="Georgea"></asp:Label>
</td>

It's always setting the label as visible whereas when the item count is not zero it should not be shown to the User.

show us the code where you are binding the data to the dropdownlist.. I guess you are adding an item at index 0 of the dropdown like:- "-Select-".

private void fillList()
{
SqlCommand cmdpopulate1 = new SqlCommand("Select PName,PID from Products where PCategoryID='" + Request.QueryString["id"] + "'", con);
SqlDataAdapter da1 = new SqlDataAdapter(cmdpopulate1);
DataSet ds1 = new DataSet();
da1.Fill(ds1);
ddlProducts.DataSource = ds1;
ddlProducts.DataTextField = "PName";
ddlProducts.DataValueField = "PID";
ddlProducts.DataBind();
con.Close();
}

I am calling this function on pageload

CDo the view source of the page when it is running
and check what is the value is set with Visible attribute

Visible='<%# bool.Parse((ddlProducts.Items.Count==0).ToString())%>'

i think its better if u check it on page load where u required it as,
if(ddlProducts.Item.Count == 0)
{
lblMessage.visible = true;
}
and keep its visible property in aspx syntax visible="false". i think this may solve your problem.
