Add a checkbox column to your grid. When user clicks on delete button or whatever for deletion, just filter the rows which have the checkbox checked and delete them.

This is going to be dumb, but I can't figure it out for the life of me. I am using placeholders in a global resource file, I have found that the string is too long so I want to put in a line break dynamically, now since this is multi lingual the break may need to be in different places depending on the language. When I enter "
" as one of the placeholders it encodes the text which makes the HTML not render no matter what I do. I have tried to decode it, but that didn't work. My string looks like this Results for room {0}.{1}All shown rooms are suitable for {2} adults and {3} children Here is my code (the br may not show up)
divResultsHeader.InnerText = string.Format(Translate("resultsHeader"),
RoomNum.ToString(),
"<br />",
infoObject.ReservationRoomInfoList[RoomNum-1].NumberAdults.ToString(),
infoObject.ReservationRoomInfoList[RoomNum-1].NumberChildren.ToString());

Use the InnerHtml property instead of InnerText.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
That didn't work, it's still encoded the br tag.
|
|
|
|
|
Then you did something wrong. What does the code look like?

Looks exactly the same as I posted earlier but I changed InnerText to InnerHTML. There should be a < and > surrounding the br tag, when I post that in here it actually puts a line break, but this is exactly what I have in my code. The Translate function just gets the string from my global resources file.
divResultsHeader.InnerHtml = Server.HtmlDecode(string.Format(Translate("resultsHeader"),
RoomNum.ToString(),
"br /",
infoObject.ReservationRoomInfoList[RoomNum-1].NumberAdults.ToString(),
infoObject.ReservationRoomInfoList[RoomNum-1].NumberChildren.ToString()));

You are obviously not seeing the result of that code. Check that you are actually watching the page where you change the code, and that the page is not cached.
I tried this code in code behind:
int RoomNum = 42;
int NumberAdults = 2;
int NumberChildren = 1;
divResultsHeader.InnerHtml = string.Format(
"Results for room {0}.{1}All shown rooms are suitable for {2} adults and {3} children",
RoomNum,
"<br/>",
NumberAdults,
NumberChildren);
The element in the page markup code looks like this:
<div id="divResultsHeader" runat="server"></div>
The resulting code in the page looks like this:
<div id="divResultsHeader">Results for room 42.<br/>All shown rooms are suitable for 2 adults and 1 children</div>

You are right, during testing I was messing with encoding and decoding so I rewrote the div using an innertext. Thanks for your help.

Hi, Whatever i can do in vc++ can it also be done in c#, or is there any thing which is done in vc++ but not in c#???????
|
|
|
|
|
Well, C++ code can run without the .NET runtime, so that's one thing.
Why do you ask ?

i want to know which is more powerful c# or vc++. and is microsoft still supporting vc++ or vc++.net.
|
|
|
|
|
Well, this can be a bit subjective. VC++ was designed to extend the power of C++ with ready to use visual components(technically MFC and SDK).
That means, using VC++ you can do more low level programming compared to C#.
C# on the other hand is generally considered a better option for RAD(Rapid Application Development).

DateTime? deathTime = null;
if(DateTime.TryParse("somedate",out deathTime))
else
The above shown code won't work as DateTime.TryParse accepts DateTime, not nullable DateTime. So how do we parse a nullable datetime ?
I made it working by the below code, don't know this is the correct approach.
DateTime tmpDateTime;
DateTime? deathTime = null;
if(DateTime.TryParse("somedate",out tmpDateTime))
deathTime = tmpDateTime;
else
Any ideas ?

|

Yes, that is the way that you have to do it. The out parameter can not be anything but a DateTime variable.

Thanks Guffa.
I wonder, if they can introduce nullable DateTime, why don't they add an overload to TryParse which accepts nullable DateTime ?
|
|
|
|
|
Because every function everywhere would need an override that supports the nullable versions, which would get quite messy

The TryParse method has no use for a nullable variable as out parameter, and it doesn't make sense to introduce something that isn't used.
It could have an overload without an out parameter, that returns a nullable value where a null value represents a failure to parse the string, but then you would have overloads with different semantics. That's not a good way to use overloading.

Ok, I've solve the question my self. Simply use the File.Copy() function to do it.

Dear All,
I want to generate the highlighted code in C# by CodeDom. Now I am able to generate all the codes except the method invoke parameter, which is this one: "IdentityNo"
foreach (CCCRM.PatientRow dr in ta.GetAccessHusbandAndWife(IdentityNo))
{
}
The code that i am using to generate the above c# codes are:
webMethodDeclaration.Statements.Add(new CodeSnippetStatement("foreach (" + module + "." + parameter_1
+ " dr in ta." + methodInfo.Name + "("));
// Parameter list for Table Adapter Method
for (int i = 0; i < methodInfo.GetParameters().Length; i++)
{
string str1 = methodInfo.GetParameters()[i].Name;
webMethodDeclaration.Statements.Add(new CodeSnippetStatement(str1));
}
webMethodDeclaration.Statements.Add(new CodeSnippetStatement("))"));
but apparently they are not right. i was trying to use CodeMehtodInvokeExpression class, but it generates different souce code.
I do appreciate your help and thanks in advance.
