How to bind nullable bool to checkbox in MVC 2. I try with this code in view:
<%: Html.CheckBoxFor(model => model.Communication.Before)%>
But show me compilation error.
Why can't I do this?
if ((bool)Request["genericError"] != true)
{
return;
}
Compiler gives me:
Cannot convert type 'string' to 'bool'
Request["genericError"] should be an object, so why does the compiler think its a string?
I'm looking for the reason for this, not how to sidestep it (using Convert)
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 3 RepliesIf 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.
View 3 RepliesI would like to add a checkbox to my grid view to represent a bool property of the list the grid view is bound to.
I want to show a checked checkbox for true instead of just showing text of 'true' or 'false'
Is this possible. When I try to add the checkboxfield in the gridview wizard. The add button is grayed out when selecting checkboxfield
I have a table in my Database called Creditors.
One of the columns is Paid which is type Bool.
On my aspx I have an objectdatasource and gridview. In the DAL is a method called GetCreditors which
returns all the creditors into the Gridview.
In some cases the "paid" column is ticked and in other not.
I want to run a select query that only gets the rows where PAID is not Ticked. insead
of retrieving all.
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:
<asp:HyperLink runat="server" ID="lnkReview"
NavigateUrl='<%# Eval("EnquiryID", @"selectcompany.aspx?enq={0}")%>'
Text="Review Enquiry"
Visible='<%# ((bool)Eval("Locked"))==true? false : true %>' />
...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 string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.
