How do I modify to trim all strings?
Suppose i am having 25 character length string and I want to bind only first 15 character of that string into the label control.
<a href="[URL]" >"<span class="name" style="text-align: left; font-family: Arial; color: #0094DA; font-size: 14pt">
<%#Eval("Name").ToString().Length >= 30 ? Eval("Name").ToString().Substring(0, 30) : Eval("Name").ToString()%></span></a>
I want to show just a part of a string for example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
Just a: "Lorem ipsum dolor sit amet, consetetur sadipscing..."
Which method can I use to do that?
I am trying to update my table ARTICLES and it has a field COUNTER, Everytime a user enter this ARTICLES, the page_load event runs a LINQ to SQL query taking the QueryString as parameter, increasing the COUNTER field in 1.

I'm trying to to display the first 50 characters of text from a database field.
I thought I could do it something like this: <%# Eval("BodyTxt").ToString().Trim("50")) %> but it doesn't work.
I've also tried this: <%# Trim(Eval("BodyTxt")) %> although I never expected that to work.

I need help for extracting a string in a formula field.
Example :
String= CFG:1,132578992,1958| result should be 132578992
String= CFG:2,158974,1953| result should be 158974
in the string always starting part is "CFG" and ending part is "|" how can i trim the string after the first comma .
I'm looking to translate an SQL query into linq
INNER JOIN Usrs ON
SAQ.UserId =
Usrs.UserId AND Scan.UserId =
Users.UserId
I'm not sure how to include the "AND" in the LINQ statement.
This is my first class ever buildt (I am a real beginner) in C#. My aim is to "Sanitize a string". The class should do: trim an input make the first letter upper case. Is there a way to better code it? Would it make sense to use a PARAMETER for a method like: CapitalizeFirstLetterTrim(string x) when I initiate an object I need write a lot of code like below, any other way to make it shorter?
UserInputSanitizer myInput = new UserInputSanitizer();
myInput.Input = " ciao world";
string ouput = myInput.CapitalizeFirstLetterTrim();

// Make First letter UpperCase and the rest levae lower case
_output = _input.Substring(0, 1).ToUpper() + _input.Substring(1);
return Output;

I need to find out which states in the "query" are not included in the "query2".I can loop through 2 results with nested loop but I think there might be better way of doing the same task with LINQ.Please show me the right direction if it can be done.

View 5 RepliesI am facing a big problem with simple linq query.. I am using EF 4.0..
I am trying to take all the records from a table using a linq query:
var result = context.tablename.select(x=>x);
This results in less rows than the normal sql query which is select * from tablename;
This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..
This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?
I am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
Example:
[URL]
I added the iis tag because I am guessing it also depends on what server technology you use?
I m facing some problem. i m not passing Dynamic string through query string..
I m using this code
string abc = "CPCB_" + TextBox1.Text + "_" + TextBox2.Text;
Response.Write("<script>window.open('xml.aspx?Flag=3&date='+abc,target='new');</script>");
I have a web app for our golf club. When I compute handicap index for each golfer, I have to select the most recent scores and then a subset of those scores depending on how many rounds of golf the golfer has played. All the scores are entered into a single SQL Express table called "Rounds". Verbally, this is what I'm trying to do:
1) select the twenty most recent golf scores (sort on date descending, "take(20)") [if less than 20 records, then select all available];
2) for this set of records, select the 10 lowest scores (or smaller number if golfer has less than 20 rounds);
3) compute the average round differential for the subset of records, etc. to calculate handicap index (this step is working ok...)
My current VB code has this LINQ query (which is flawed -- it selects the lowest handicap differential scores of ALL records for the filtered user):

How do I modify this query to accomplish items 1) & 2) above? It seems this should be simple, but my experience with queries is still limited.
Is It Possible to send a string consists of (,.&') in a query string ?
View 7 RepliesI have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
View 2 RepliesI wanted to create a URL like http://localhost/menu.aspx/?id so that on typing this, it displays all the id's in the database. for eg:134
123
543
234
may be the id's which should be displayed after fetching from the database. However, it should be displayed as it it is without any control or without arranging in any gird etc. How can that be done?
