If I chose none, it stores data as "Null" If I Query the data as below, I don't get the data has value of "Null" SELECT tabale From type Where type <> STO or type <> ORD I get data that has empty string but not Null.
1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.
2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD

For coonverting Linq to DataTable I am using the following Extension Method(Taken from Stackoverflow)
L[code]....
The Extension Method creates XML file.But for null values no element is created in XML file.Say if Commission field is null then commission element is missing in Xml generation.
I want to insert element with empty string for null values (ref type) and (0.00) for decimals and (0) for integers. where do i need to make change?
We have an ASP.NET web service that invokes a stored procedure on our DB (Oracle 11g). The problem is that the call to the procedure blows up every time an empty string is passed as one of the parameters. We're seeing an ORA-01084 error, which indicates to me that call is failing before the procedure is actually run.
Here's the procedure, minus some logic that I believe is not relevant:
[Code]....
As an experiment, I modified the web service to pass null rather than an empty strings. When null is passed in, I see an error indicating "wrong number or types of arguments in call to 'CREATEREPORT."
I also tried passing DBNull.Value whenever the params were null/empty, but that resulted in the error
Parameter 'p_column_id': No size set for variable length data type: String.
(Of course, p_column_id was the empty parameter in this case).
So, how can I successfully pass empty strings as parameters to my stored procedure? We definitely want to allow the p_column_id parameter to be empty.
If I have JSON like this and pass it to the engine I am using to create a PDF file, the word "null" appears on the PDF. This isn't really my example, but I googled "json replace null empty string" and this was a hit, which is a good representation of my data, also:
We use a rendering engine that creates a PDF from a fixed template and variable data in the form of a json string. But our customers don't want to read that the id is "null", they want to read that the id is blank. In my C# program, the json is just a string, so I can easily do something like this:
jsonString = jsonString.Replace("null,", ",");but the issue is I can't replace null-comma with a comma, because then it's invalid json.
how to I make the rendering engine *and* my customer both happy?
I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
I have set the value of an int parameter to the attribute of a textbox.The textbox can be empty or null, how to check whether the parameter is empty or null?
Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing if txtBox1.text.toString isNot nothing if txtBox1.text <> "" if txtBox1.text.toString <> "" if isNull(txtBox1) Is there on test that can cover them all?

There are two dropdowns in my ASP.NET form. The second dropdown is dependent on the first dropdown - the second onedoes not have the item selected in the first one. My problems is that the selectedValue for the second dropdown is always empty after load event. I tried to set the selectedIndex to be 0 before access selectedValue property in the page load event, but it is still empty. What I want is to get the first item of the second dropdown as the default value.
I have a repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:
[URL]
However,I am not sure how to write the logic for hiding and showing the placeholder.I have written some code for the same but that clearly doesn't work.The following is the .aspx as well as the code behind which I am using:
I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?
I have a asp:menu that's using data from a .sitemap file. This site is running on server 2003 asp.net 2.0. I assume IIS v6? When using IE9 normally the dropdown menu shows but you can't select anything from it (the pointer goes away when you hover over it) and it disappears. If you go into Compatibility mode, the dropdown menu shows and you can access the menu items but the item hover background color is lost (supposed to be white with #CC0000 text. Background is #CC0000 so you can't see the text).
This didn't happen with any other versions of IE. If you check it in any other browser, it works as expected. Funny thing is if I run it out of my local IIS v7 (Win7) or my dev server from VS 2010 (localhost), it works fine in IE9.
I just recently got complains from some of my customers, that their drop down menu does not work in IE. The drop down menu is just a white frame, and when navigating down the menu disapperas. I investigated the problem, and found that it works fine in IE6 and other browsers.
I have a couple of drop down list inside a update panel and a asp:menu. When the site is accesed with IE6 the asp:menu appears behind the dropdown combos. I already try fix it with z-index but nothing happen, the dropdown still appears in front of asp:menu. is a bug in IE6, or there is a workaround? This not happen with IE7, IE8 and Firefox.
I cannot change the text in the drop menus. It was originally "Select a General Market", and "Select a Market". I have changed them and the changes due not take effect. I can change the labels, but not the default text inside the dropdown list. Is this something that needs to be changed elsewhere?
<asp:label id="lblSelectGenMark" runat="server">Select a market: </asp:label> <asp:dropdownlist id="ddlGreaterMarket" runat="server"> <asp:ListItem Value="None">Select a market</asp:ListItem> </asp:dropdownlist> <asp:label id="lblSelectMark" runat="server">Select a region:</asp:label> <asp:dropdownlist id="ddlMarket" runat="server"> <asp:ListItem Value="None">Select a region</asp:ListItem> </asp:dropdownlist> <asp:button id="Button1" runat="server" Text="Filter Scores"></asp:button></P>
I have a textbox where email addresses are displayed at the click of a button. There is one problem, before the first email address there are two empty spaces. Is there any way of getting rid of them? The result looks like this: " emailaddress; emailaddress; emailaddress;"
