I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.
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 have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
I am tryin to get records where certain fields are empty, but the following sql does not give me correct result.
SELECT [specimen Type], [Year], [Lab Number]
From [PET Fish] where
ltrim(rtrim([Diagnosis])) = '' or
ltrim(rtrim([Results])) = '' or
ltrim(rtrim([Sign out Date])) = ''
It should return all records, but it returns none.
I am working with a gridview that pulls data from a SQL database based on selections in dropdown lists. The source table has six columns for attributes of the selection, but depending on what is chosen, there could be anywhere from one to six of those that are empty (all null values). When the column is empty, I would like to have it hidden so the page is less clunky and confusing.
I've searched around for an answer for the past couple days, but what I have found so far is either related to hiding columns that you know are empty which I will not know or removing them in the SQL code which I think doesn't work if the column is called for in the gridview code and doesn't exist in the query.
How do I check if my value is empty AND Isnull? I need to check for both, using ISNULL is not enough because the data can change just so that it is empty.
how I can change my query to accommodate this?

I have a FormView with a byte field. The field is not required and if I don't enter a value, I get an error that the value is not acceptable in a byte field. I can replace the null value with 0 but I would prefer not to.
What is the best way to handle this so that if I do not enter a value in a byte (or int16) field to insert a null value (or whatever they do in the ASP.net).
I am using ASP.NET and VB to display a message(label) while the datalist is empty like this
<asp:Label ID="lblEmpty" Text="No Data To Display" runat="server" Visible='<%#bool.Parse((dlErgebnis.Items.Count==0).ToString()) %>'></asp:Label>
I am getting a error "the name bool is not declared".
What is causing this error?

View 1 RepliesI have a Formview control that has several lookup fields. The value is an int ID but the textfield is the name, e.g. value = StateID, displayed text = StateCode)
If the user leaves that field blank, I get a Server Error when attempting to Update: Failed to set one or more properties on type orgOrganization. is not a valid value for Int32.
In the table for the LinqDataSource which provides the data for the Formview, all fields except the text field OrganizationName allow Nulls.
Does anyone know why this might be happening? I tried a test which just has the numbers, no lookups, and get the same result.
I have a web form and I have a user control on it. This user control contains a panel with some user properties that are to be stored in a database. So far nothing fancy. The user control itself contains a panel and is working fine (all code to retrieve and store the values is working).
I used the default settings of creating a user control and one of them was AutoEventWireup=true. This works fine because I also have some dropdown boxes (and other fields) that need to be filled with values from the database and that happens in the Page_load event.
The panel specifies the 'DefaultButton' which calls a method when clicked to save the values after the user has changed them.
On this click the code of the method is called, I confirmed that, but I found out that the values of my controls on the user control (for example the Textbox control) are empty. As a non-ASP.NET developer I couldn't figure out why. So I changed some settings like AutoEventWireup to false.
Off course this resulted in my dropdown boxes no longer to be initially filled, but my surprise was big to find out my controls actually contained the values the user typed in.
Logically I need both the values and the dropdowns filled, but for now it seems one or the other.
I have datalist in product.aspx page that bind from database and there is Repeater that bind from database... when I click on item from repeater it bind datalist... and I define Label =LBLerrorS that when there isn't any data in database it show this message="There isn't any Product"
