I have a textbox with a RegularExpressionValidator. I want to require the user to enter at least n characters. I'd also like to remove whitespace both at the start and end of the textbox. I'd still like to allow spaces within the textbox, I just want to remove the excess at the beginning and end. I basically don't know how to combine the trim regex and the count together for use in a REV.
trim: ^s*((?:[Ss]*S)?)s*$
count: .{10}.*
I basically want to know if the input, after leading and trailing whitespace is removed, is greater than n characters.
When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.
I HAVE A GRID VIEW IN asp.net + VB Code. There is a drop down list and the selected data is displayed in web page. I placed a label in web page and code behind i used following code.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound Label1.Text = GridView1.Rows.Count.ToString() Dim ONYO As Integer = 0 Dim DONE As Integer = 0 For i As Integer = 0 To GridView1.Rows.Count - 1 If GridView1.Rows(i).Cells(0).Text = "ON YO" Then
a typical Unique Identifier looks like this "e7321a77-8422-408e-90ed-eb3df9aca4d8"How can I trim that down to display only first 23 characters? I would like to display that output in a label.
for example:
lblUID.text = "e7321a77-8422-408e-90ed" can someone give me a vb.net 3.5 example?
I would like to use the trim() method to remove white spaces at the beginning and/or end of text entered in text boxes that are in Insert and Edit Item templates. example with the code below if there is a way to do this?
Is there an easy way to trim values in a details view during edit mode? I tried modifying the database query to trim the values, but it didn't like to do both ways databinding after that. I tried looking through all the properties of the text boxes themselves and found nothing. I know I could add an event handler for the databound event, and set all of the values one by one, but this is an application that has existed since before my employment and there are over 40 values in this details view, all in text boxes with seemingly random names that have little to do with the values they represent or obvious naming scheme.
I thought maybe there was a way to way to iterate over the DetailsView.Fields property, but couldn't figure anything out there either. I am not allowed to change the schema from CHAR to VARCHAR either. Any other quick ideas? There is a strong likelihood this page will change again, and I would like something that might take care of this problem for any new fields added in the future without extra work. Unfortunately, redesigning it is not anywhere near a top priority right now, so a quick fix to alleviate some of the headache of using this monstrosity is all I am looking for.
I have a repeater that generates last names. My issue is for the names like Smith, Jr I want to remove the comma and everything after it so that is just displays Smith. I thought the code below would work, but it doesn't.
how can i apply string.trim() accross the website when saving or editting data on the model rather then on individual fields accross the site in the controller.
On a button click, I want to select all items in a listbox, the items will look like this for example: '14/5', then I want to extract the digits on each side of the slash for each item. The digits will be different every time and can consist of any number of digits. Do I need a loop to be sure to get all items?
I am using a gridview populated via a SQLDataSource. When editing or inserting data via the gridview, how do I trim the values before they are inserted to or updated in the database? I want to ensure that no spaces are accidentally added to the end of my text values.
I have a LinkButton that is databound to a description. Sometimes the descriptions are very long and unorganized so I would like it to show for example 75 characters and then append a '...' to the end of any description greater than 75 characters. I found this snippet which pretty much is exactly what I want to do : from [URL]
[Code]....
I just cant figure out how to do this for the LinkButton in my ItemTemplate in the DataList.
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(); Useful resource http://msdn.microsoft.com/en-us/library/bb311042.aspx ----------- CLASS using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace WebProject.Core.Utilities { public class UserInputSanitizer { // Backing variables private string _input; // Properties public string Input { set { _input = value; } } private string _output; // Backing variables // Properties public string Output { get { return _output; } } public string CapitalizeFirstLetterTrim() { // Trim _input.Trim(); // Make First letter UpperCase and the rest levae lower case _output = _input.Substring(0, 1).ToUpper() + _input.Substring(1); return Output; } } }
I want to create a 'news' excerpt for the front page of my site. So I get the first news item ordered by date and then I want to display it but cut down to a number of words.How would I do this with vb.net?
I have a text field where user can enter either an URL or an Email address. How can I use a RegularExpressionValidator to validate that user have entered an URL or an Email address
I had a question on here for a RegularExpressionValidator which I'm relatively new to. It was to accept all alphanumeric, apostrophe, hyphen, underscore, space, ampersand, comma, parentheses, full stop. The answer I was given was:
"^([a-zA-Z0-9 '-_&,().])+$"
This seemed good at first but it seems to accept amoung other things '*'.
