I have a list view with a HyperLink control within the ItemTemplate. I want to display the link if a returned value is 0 (false), and not display the link if it is 1 (true). So far I have this:
...but this renders an 'Specified cast is not valid' exception. Examples I've seen elsewhere suugest this should work. I can confirm that the Locked column only returns 0 or 1 (from SQL Server) - surely these should be easily cast from bit/int to bool??
I have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :

As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me.
I have the following query in which I have to convert the 'bool' valu into 'string' value as "Y" or "N". I have a class defined called ChartDosCodeInfoStruct which definesQAIndicator as String. The value I am feteching from DB is a bool value. I need to take this bool value and accordingly assignQAIndicator= "Y" or "N".
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".
If I'm returning an object, then it's pretty straight-forward. However, if I'm just trying to return whether or not the method was successful or not, what's the best option? Sure ... bool seems obvious - but what if you need to debug or get some additional details out of the method than just "yes/no"? Well that's where a string becomes more obvious, right? You can leave it empty to say that the method was successful or chock it full of details in the case of an error. But this can make it less intuitive to others who may have to run your functions and it also jumbles up everything you wanted to pass back into one large string.
I'm using linq to sql to populate a list of objects. One of the fields I'm interested in is stored as a tinyint. How should I declare this property type in my object definition? As a Short? Byte? Int16?
I have this problem where I am passing NVARCHAR parameter to a stored procedure, and the field type in the table for that parameter is INT.
I am doing that because I am using IN function, and for example if I want to send multiple parameters, that is the only possible way to do through .NET. Or not? The SP doesn't get executed because of the wrong type, and I am trying to cast the value, but I get an error. Here is how I am trying: Example:
@Parameter nvarchar OrderStatusID = ('30, 40')
(o.OrderStatusID IN (CAST(@OrderStatusID as int)) OR @OrderStatusID IS NULL)
Is there a way to cast each value separately, or what will be the best way to cast whole value as INT.
I worked in C Sharp code works vote and found the problem appointed Data ReaderIf you will allow me in the solution

The GenerateRowColumnDataTable method retrieves all form variables with <input> tags. My problem is that my columns are named in a strange format like this:
#X#_G1_NAME_1 so when I look at what's being rendered I see %23X%23_G1_NAME_1 so I thought I could use Server.URLEncode() around Request.Form but I'm getting an errot that it can't be converted to a string. What would you do in this case?
I have a bit column that is saved as 1 or 0 in the database. I want to check the value in the table and then do an if statement depending if its 1 or 0. How can I convert it to an int?
i had
lockValue = (int)sqlCommand1.ExecuteScalar();
I want to assign it to the lockValue int variable. I then want to go on and check
Why it's not possible to cast a SiteMapNodeCollection (eg. SiteMap.CurrentNode.ChildNodes) to an IEnumerable<SiteMapNode>? I was wanting to do some filtering of the collection via LINQ, but this might not be possible?
The MSDN page says it implements IList, ICollection, and IEnumerable, so I don't see what the problem is.
I have a situation where I'm iterating through all the controls on a form, specifically looking out for any of these three types of controls: Labels, TextBoxes, CheckBoxes
I can, of course, get the type of the control and then use a Switch-Case construct to cast labels as Labels, textboxes as TextBoxes, and checkboxes as CheckBoxes.
But I'm wondering if there's a way to do something with one or two lines of code to gain access to the Text property of each of these controls?
