TextBox within DataTemplate for ContentPresenter not triggering update event

Posted By:      Posted Date: October 26, 2010    Points: 0   Category :WPF

I have designed a complex DataTemplate to re-use among several ContentPresenters I have on a dialog. Within this DataTemplate I have a TextBox that is bound to a DependencyProperty of a custom UserControl. I'm having trouble setting the binding correctly to get updates reflected in my viewmodel. Setting the TextBox text from the property value works correctly, but not the other direction, updates when the user changes the text are not updating the source. I've created a small sample program to illustrate the issue.


<Window x:Class="TestBinding.MainWindow"
    Height="203" Width="223">
    <DataTemplate x:Key="CustomUcTextBoxTemplate">
        <Grid >
          <TextBox x:Name="testTextBox" Height="28" 
            Text="{Binding Path=Title,
               RelativeSource={RelativeSource FindAncestor, Ancest

Composite control: How to bubble a textbox's TextChanged event?


I've created a composite control that contains several controls, including a textbox. I'm trying to expose the TextChanged event of the textbox as an event on the composite control. I understand that events can be bubbled up the control hierarchy and handled at a higher level, which I've attempted to do, but I can't get the bubbled event to fire. When I drop the control on an aspx I can see the TextChanged event, I can subscribe to the event, but nothing ever happens. Any suggestions? Here is what I think is the relevant code:

// My event
private static readonly object EventTextChanged = new object();

//Handle the bubbled event
EventHandler textChangedHandler = (EventHandler)Events[EventTextChanged];

protected override bool OnBubbleEvent(object source, EventArgs e) 
    bool handled = false;

Textbox text populated by Session Variable wont update into SQL with new text


Hi everyone, I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

Why would the button click cause the textbox refresh with the text from the pageLoad before updating the data source?

Event Hanlder to update other SQL tables



I'm writing a small app to allow viewing and editing of a single SQL table (the _Assets table).

I have a form-view that allows the data to be viewed (ItemTemplate) and edited (EditItemTemplate).

Everything works well. All the SQL editing is done in the Mark-Up using a simple SqlDataSource, asp:Parameters and data-binding, (ie. there is no VB code behind).

However, I need to write an event-handler which updates other tables when the EditItemTemplate INSERT button is used.

This event handler needs to update OTHER SQL tables.

The idea is to create a HISTORY of changes (Updates) made to my _Assets table.

It would look something like this:

IF the value of the _Assets.Comments field is changed by the formview, then:

Open SQL connection to _CommentsHistory table

Update _CommentsHistory

SET CountrySerial = asp:Parameter Name "CountrySerial" from SqlDataSource ID="FindAsset"

SET OldComment = [the original Comment] asp:Parameter Name "Comments" from SqlDataSource ID="FindAsset"

SET NewComment = [the New Comment inserted in the formview] TextBox ID="CommentsTextBox" from FormView ID="FormView1"

SET ChangeDate = { fn (now)}

Set ChangedBy =

Changing a textbox's readonly property right before update on a gridview


I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?

Triggering an event to occur within a VB.NET app if something is inserted into an SQL Server table

Let's say SQL Server is inserting arow within a table. Is there a way to let VB.NET know that an event was fired (being the inserting of the row within the table), without the need to query anything. Bascially having SQL Server tell the VB.NET app that an event was fired. It seems like it might be possible using CLR and the .NET framework integration wthin SQL Server, but I haven't found a sample program showing what I'm attempting. I understand that this topic covers SQL Server and VB.NET.  This need being for both and this forum only set for SQL Server, I thought I'd take the risk and post in this forum. Thank you in advance for any assistance.Newbie

OK button click on Windows dialogue form not triggering click event

I have created an Add-In for Outlook 2003 in Visual Studio 2005. When a new message is sent and a toggle button is selected, a form that I have created will be displayed as a dialogue box, where further information can be entered. Once this information has been entered you can click the OK button and the message is sent. If you were to click the OK button with invalid data in the form, there would be a message box with an error message. This all works perfectly on my development machine but when I have packaged the Add-In and installed it on other machines it does not work. Clicking on the OK button does nothing, there is not even an error message. All the prerequsits are successfully installed and this is the only part of the Add-In that does not work. All help greatly appreciated. Thanks Nick

Javascript to update value in Textbox

Hi I have a javascript file, which creates a calendar picker. This file is used through out the application and is a piece of code that I have to use because my .Net application is part of another application which uses this piece of JavaScript code.Anyhow, with the calendar picker I can save the date into a textbox, but the problem that I have is the format. Unfortunately, I cannot change the calendar picker code because this will affect other parts of the application. Therefore, what I am looking to do is to reformat the date on the textbox control. This I can do but only when I use the javascript event onfocus.Now, my question is this, is there away in javascript or with jquery that when a value enters into a textbox that this value is then reformatted to the format I want without postback or clicking on the textbox?Thanks

Infopath Changed Event code triggering in preview but not in web filler.

Hi there, I've written some code for a changed event hookup on a field in infopath 2010. The form is for submission to a sharepoint 2010 forms library. What the code does is fill in a specific value into a field depending on the selected value from a combo-box elsewhere on the form. When i preview this in Infopath 2010 it works perfectly but when i fill out the form through the web interface it simply does nothing. I've got another piece of code which executes on load and this works perfectly in both the preview and the web filler. What it does is just set the value of a field when the form loads. Here is the code, could someone tell me what i'm doing wrong? public void InternalStartup() { EventManager.XmlEvents["/my:myFields/my:service_level"].Changed += new XmlChangedEventHandler(service_level_Changed); EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading); } public void service_level_Changed(object sender, XmlEventArgs e) { // Write your code here to change the main data source. XPathNavigator xroot = MainDataSource.CreateNavigator(); XPathNavigator serviceLevel = xroot.SelectSingleNode("/my:myFields/my:service_level",NamespaceManager); XPathNavigator xest = xroot.SelectSingleNode("/my:myFields/my:est_cost", NamespaceManager); switch (serviceLevel.Value)

TextBox AutoPostBack not working when handling other DHTML event


I have to format a number in a TextBox while it is being typed. Right after the TextBox looses focus, I need to do other processing on server side, including some database queries.

I'm doing the formatting by handling the onkeyup event, client side. But when I add the handler, the onTextChanged event stops firing on the server. I've tried different return values for the handler but unfortunatelly I'm stuck.

To reproduce the problem, here is a sample where the formatting function was replaced by a simple "convert to uppercase" function. You'll see that, contrary to the expected, the Label doesn't get filled when the TextBox looses focus. It does get filled, however, if the user presses the ENTER key.

What can I possibly be doing wrong with such a simple task?


<%@ Page Language="VB" %>

<script language="VB" runat="server">

Sub Page_Load(ByVal Sender As Object, ByVal E As EventArgs)

'' Adding the event handler like this has the same effect as adding it inline

'txtTextBox.Attributes.Add("onkeyup", "return(upperCase(this));")

End Sub

Protected Sub txtTextBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)

lblTextBox.Text = S
