I am looking for a regular expression for c# asp.net 3.5 that will fail if there are ever any double spaces in a sentence or group of words.
the cat chased the dog = true the cat chased the dog = false (doubles spaces occur at random intervals)
How can I write regular expression in C# to validate that the input does not contain double spaces? I am using Regular Expression Validation. However I do not know what is the Validation Expression to get the result.
"white snake" : success
"white snake" : fail
I have code like this
string pattern = "<(.|
)+?>";
System.Text.RegularExpressions.Regex regEx = new System.Text.RegularExpressions.Reg(pattern);
string result = "";
result = regEx.Replace(htmlText, "");
In this "htmlText" will have some html code which also contains break tags. Right now its replacing all the html tags, but I want to leave break tag and replace the rest.
I would like to use a regular expression in C# to turn any two or more spaces into non-breaking spaces. I would like to leave single spaces alone.
Sample Sample
Would produce

But

Wouldn't be affected.
How can I make this regex not accept spaces?: [0-9a-zA-Z' ']{3,}
Everything I'm reading says to put a * or a + after the [] , but I get an invalid expression error when I do. The end result I'm looking for is a string of letters and numbers only - no spaces inbetween.
am using this function to remove whitespaces at html output. i had to put if else otherwise page was giving error afterasynchronous postbacks. now it works fine.is it possible to make it work also after asynchronous postbacks ?also is it possible to make this regex function also removes new lines ?like how google doesthere is no line at their source codes

I'm trying to complete a regular expression that will pull out matches based on their opening and closing characters, the closest I've gotten is
^([[)[a-zA-Z.-_]+(]])
Which will match a string such as "[[word1]]" and bring me back all the matches if there is more than one, The problem is I want it to pick up matchs where there may be a space in so for example "[[word1 word2]]", now this will work if I add a space into my pattern above however this pops up a problem that it will only get one match for my entire string so for example if I have a string
"Hi [[Title]] [[Name]] [[surname]], How are you"
then the match will be "[[Title]] [[Name]] [[surname]]" rather than 3 matches "[[Title]]", "[[Name]]", "[[surname]]". I'm sure I'm just a char or two away in the Regex but I'm stuck, How can I make it return the 3 matches.
I want to write a Regex in DataAnnotations that can unmatch a input string containing not paired double quote " ie. check if zero or a paired double quote allowed in a input string.
matched case:
abcde
"abcde"
abc"d"e
unmatched case:
"abc"de"
"abcde
abc"de
abcde"

I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.
I was trying to follow this tutorial on msdn, but it doesn't quite fit perfectly with my problem:

Code:

I'm using linq to sql,everything seems to be working fine except one thing,I'm showing any mapped float fields from my db tables as "Double?" instead of "Double", and when binding to a datagrid, any of those "Double?"fields don't show.If I iterate through the items and spit out the property,the float value is indeed there and properly returned.

how to exclude certain string
On my MasterPage I use UpdatePanel to update whole ContentPlaceHolder. Example of code you can find below. All content pages work fine with this MasterPage except one. This page is very complex. I noticed that when I disable UpdatePanel in my MasterPage this problematic page works fine. Question: is it possible to exclude something from UpdatePanel - in my example whole page but only this one?
<asp:UpdatePanel
ID="UpdatePanel2"
runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder
id="MainContent"
runat="server">
</asp:ContentPlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>
All my entities have the following properties:
public virtual DateTime CreatedDate {get; set;}
public virtual string CreatedBy { get; set; }
public virtual DateTime UpdatedDate { get; set; }
public virtual string UpdatedBy { get; set; }
I've implemented a EventListener (IPreUpdateEventListener, IPreInsertEventListener) so that I can fill these properties before inserting/updating my entity.I do not load my entity just before saving cause I've got all my fields in a view (id, version). The only thing I would like to avoid to put in hidden fields (of my view) are CreatedDate and CreateBy.Since I fill these fields only once, when the entity is created the first time, I was wondering if there's a way to exclude them when I update (only update) my entitiy?!
I have a VM which contains a DTO inside it and DTO again contains properties.
it is like this :
[Code]....
Now i attach this VM to a View and expect the contactPersonVM as parameter. I am using same View for both Create and Edit. When in Create Mode i don't want SysId property to be attached as it is not required in create Mode.
This is the code for create action:
[Code]....
Though i have Excluded SysId from Binding but its still giving me ModelState error of "SysId is required". If i attach a Bind attribute directly to ContactPerson DTO then it works but then it applies for both Create and Edit. I want Bind attribute to be only for Create Action.
In MVC2, why the BindAttribute Exclude doesn't work?
I have two Controllers that calls the same model object on submission, however, one page must be exempted from the model validation but below doesn't work.

I would like to exclude one of model's property from the Html.EditorFor. I tried [HiddenInput(DisplayValue=false)] but it renders the property as an hidden input. This could potentially be a security problem. How can we completely exclude a field from Html.EditorFor?

I have a routing setting in my global.asax file:
routes.MapPageRoute("video-browse", "video/{id}/{title}/", "~/routeVideo.aspx");
My routeVideo.aspx page has caching setting:
<%@ OutputCache Duration="10" Location="ServerAndClient" VaryByParam="id" %>
But when I request http://localhost/video/6/example1 and http://localhost/video/6/example2 after this, the page is created again. So I think VaryByParam works for * but I only want compile when id changes. Is there a way to define routing parameters at VaryByParam?
How do I stop a TEXTBOX from rending on user click?
I have a gridview, a button, a textbox (for searching string) on my web page. When the button is clicked the data is exported from the gridview to MS EXCEL. I am having issues with the following code. It execute the export to MS Excel when the user click the enter key.
NOTE: My application works fine except for when the user clicks the enter key on the keyboard the export seems to be triggered. I do not want that to happen on enter.
CODE:
Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
'Confirms that an HtmlForm control is rendered for the specified ASP.NET server control at run time.
End Sub
GOAL: How do I specify only the Gridview control to be rendered, when the above function is called.
Only gridview control when the button is click. No other user activity should execute the the MS Excel export. I would like to exclude textbox control from VerifyRenderingInServerForm?

I have a table of products and it has a productID field and a setID field.
Products can be grouped together by making the groupID the same for the both of them.
I have only @productID parameter. My goal is to get a list of products minus this product and any other product that it is grouped with (ie..setID is the same).
Here is the query that I wrote because it has worked when excluding products from another table. I used the explicit GUID and still nothing.
