I have a ListView control that might be empty sometimes. I would like to show a text message like: "No items to Show" when the ListView is empty.
I have read the FAQ of this forum. This issue is not there.
Is there any way to enable alternative ListView (LV2) or any other control in case when ListView (LV1) returns no records from DB? I already have emptydatatamplate designed for this case, but I need to enable a new ListView below in this particular case and I don't know how to achieve this!
View 2 RepliesI have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?

View 2 RepliesI created a database with ID, Title, Content, Date, ImgLnks, Image and Imagecaption and i'm using ObjectDataSource to populate the data. The field "ImgLnks" displays a new blank window with URL. This column is entered as text, inserted into the database and displays as clickable link in the gridview. My question is, is there a way that I can put an Alternative Standard Text in this column instead of displaying the clickable link like [URL] etc.? Text like, "Visit Page".

I am trying to rewrite an Access Database in to a asp.net front end and i have hit an issue that i can not find a good way round.
in the access version of the software there is a screen the displays all cusotmers and invoice information about these customers, there are currently 15 columns on the screen and we currently have around 25K customers and this will only go up. This is done using a multi column listbox i need to replicate this screen in asp.net but i spent all day on this on as yet not found a good way of do this.
the user will need the ability to select multiple customers at a time and because of the amount of data a scroll bar is a must, this is why the listbox is an ideal tool, apart from the fact the standard one in asp.net does not allow multi columns. grid lines would also be useful. I have look at a few third party multi column multi column list boxes but the only one that i have found that seems to work OBOUT's takes far to long to render 25K rows.
