Raise OnPropertyChanged event when Text Box Text has changed

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :WPF
Hi there I have a Wrapped Text Box that is bound to a Public String Property. I have a related OK Button that should be Enabled when the text changes to indicate there are 'items' in the Text Box. The problem is that the set accessor of the property (and thus OnPropertyChanged) is not being called until focus is lost from the text box - and I would like the Ok Button to be enabled before then. What is the the best way to raise the set when the Text Box text has changed? (A List Box is not an option) Thanks very much Joe

jquery - span text changed event


is there a jquery event that is fired when the text of a span element is changed? The change event does not apply to <span> elements. I see reference to "text changed", but $('#PriceCond').bind('textchange', function(event, prevText) { ... }) ; does not work either.



     <input type="button" id="TestButton" value="Test" />

     <span id="PriceCond"></span>

<script type="text/javascript">
  $(document).ready(function ()

    var clickFunc =
          function ()
            var s1 = $('#PriceCond').text();
            $('#PriceCond').text(s1 + 'x');

    var priceChangeFunc =
          function ()
            alert('in priceChangeFunc');





gridview tablecell text emptystring in RowDataBound event when editing


HI and thanks in advance.  asp.net using vb, using a codebehind page.

I have a relatively simple gridview bound to an product table that displays great.  The problem comes when I choose to edit a row.  When I do so, the gridviews' RowDataBound event fires and the values of the text properties of the tablecells in the row evaluate to "" emptystring. 

I do notice that if I break within the GridView1_RowDataBound event during a refresh of the page, the values are there.  But again, when I hit the "Edit" button in the first column (the CommandField column) .  Text properties of the cells resolve to ""

 Here is the code for the event, followed by the gridview in the form (inside an updatepanel)

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  ' not a header, footer row.. etc.
            Dim cellProductNumber As TableCell = e.Row.Cells(3) ' ProductNumber column

'>>>>> after clicking "update", even though a value displays in the gridview,
' the cellProductNumber.Te

gridview sort on changed cell text


I have a gridview that is being databound by an SQLdatasource and on  RowDataBound i am doing a calculation and then setting


e.Row.cells(17).text = Result


However, when I go to sort it on the website it sorts it based off the previous values.


Cell(17) from the datasource reads in all 1's. The numbers I change it to range from 0 to 15. So when I click sort nothing changes because it sees it as all 1's.

How can i make the gridivew sort off the changed text values?

AutoCompleteStringCollection for text box in DataGridView 2.0

I have been searching for a way to have autocomplete in a DataGridTextBox
object. There does not appear to be an obvious way to do this like you would
for a TextBox outside of a grid using the AutoCompleteCustomSource. Any
thoughts on how I can add this collection? :)

Built-in Functions - Text and Image Functions in SQL Server

Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

reference from menubuttons to text parts in article on the same page


Hi, I'm searching now for hours but couldn't find it.Cry

In my menu i have several buttons which (by a <a href..) should go the a part of an article that is in the same form.

Menu button : What is a database should go to the page default.aspx and in there is an article published.
A part of this article is having a piece of text about "what is a database"

Menu button: how to make a query should go to this same article in the same page but then to the part that is have the piece about the query. The next could be an example of what i'm doing:

    <li><a href="default.aspx ?????>what is a database</a></li>
    <li><a href="default.aspx ?????>what is a query</a></li>

Where my question marks are, there should be a connection to that particular piece of text.
In each article part there is an ID="text1" and the second part id="text2"

How shoudl i do that, Should i use a question mark.
Please give me some guidance how to structure the <li> statement or a pointer where I can read about it.


text editor


 I format lines in a .aspx file (source view) the way I can use them, and if I switch to design view or view in browser or debug, the many lines get reformatted to flow all onto one line.

I can't seem to find the correct setting to keep this from happening.

Any suggestions?


Unique text value in databse column


Hi Everyone!

I know this is probably a very basic question but how do I keep a column's text values unique in SQL server (ie for a unique username)?  The column is not an integer it's varchar(50), and it's not the primary key but I could make it the primary key if recommended.

The front end could handle it;  where the user would enter text, it's validated, then a query is done to see if that username is available.  If so, then user can decide to choose it and an insert is done, if not they pick a new username and process repeats.  With this approach, the responsibility of keeping the value unique solely rests on the front end, nothing on the database side.

Is this the correct way to handle this? 

Thank you!
