I have binding in TextBox
<TextBox x:Name="TbxActiveSourceNameSourceNameSourceName" IsEnabled="True" Text="{Binding ViewAudioAudio_ActiveSourceNameModel.ActiveSourceName_SourceName,UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" Padding="0,-2,0,0" Height="15" VerticalAlignment="top" Margin="127,10,0,0" FontSize="10" BorderBrush="#FF918D8D" TextAlignment="Center" Width="75px" HorizontalAlignment="Left" HorizontalContentAlignment="Right" />
But characters run from right-to-left.
How do I must to characters run from left-to-right(normal) when I input words in textBox
Many Thanks
I know this is old question but if anyone runs into this issue it happens to deal with
<TextBox Text={..., UpdateSourceTrigger=PropertyChanged}
it seems that when the property changes via keystroke it automatically detects the property change and so it updates the property it's binding to as well. Because of this it resets the cursor to the very left of the textbox rather than leaving where it was last left off.
Or at least I've been only able to reproduce this issue by changing a textbox to textblock and then back to a textbox and changing the UpdateSourceTrigger to a type that isn't PropertyChanged and would correct the issue and have the text flow right to left.
Set the FlowDirection property to LeftToRight. Reference here.

Here's the problem. I have a regular textbox that is used for number input to filter items in a list.
<TextBox x:Name="FilterTextBox" Text="{Binding FilterText, UpdateSourceTrigger=PropertyChanged}" Margin="5" />
Now the customer wants this code to be written right to left. I thought that this could be solved with FlowDirection however FlowDirection="RightToLeft" on the box does the same thing as the HorizontalContentAlignment="Right" or TextAlignment="Right" for that matter, meaning that if FlowDirection is "RightToLeft" and I type 3, then 4, then 5, the box will contain "345" aligned to the right, where I had expected it to be "543" aligned to the right, which is also what was requested.
Any idea of to get the desired effect, is FlowDirection supposted to be just a substitute for TextAlignment and I have misunderstood its purpose?
I suppose I could listen to key down event and insert the character at index 0, but I was wondering if there was a cleaner way to do it, all in xaml without code-behind.
Xaml:
<TextBox Name="txtbxExample" Width="100" Height="30" TextChanged="TextBox_TextChanged"/>
Code Behind:
Private Sub TextBox_TextChanged(sender As Object, e As TextChangedEventArgs)
txtbxExample.CaretIndex = 0
End Sub
Tested it out and typing 3 4 5 results in 543. This will probably be the simplest way to do it. Found no way to access the CaretIndex property from within Xaml using triggers, sorry.
The combobox is editable so user can also write. I have two usecases:
Get the text from combobox in a Lostfocus way, when user writes
something in the box and when he presses "Tab" then I want the text
from the combobox and I add the value in the itemsSource list.
When the users makes the selection from the combobox dropdown, I want that
selected item as soon he selects it and this time I dont
want to have it in Lostfocus manner but somewhat like
PropertyChanged way.
I tried the code which is given below:
<ComboBox Margin="3" x:Name="Combobox" SelectedItem="{Binding SelectedPath, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Text="{Binding PathLocation, UpdateSourceTrigger=LostFocus, ValidatesOnNotifyDataErrors=True}" IsTextSearchEnabled="True" VerticalContentAlignment="Center" ItemsSource="{Binding SelectedPaths}" IsEditable="True" Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="2" HorizontalAlignment="Stretch"/>
Things worked fine for the first time when the application starts but after some interactions the problem arises. When the user starts typing in the combobox the SelectedItem property of combobox triggers which is contrary to what I want in the first use case.
In short: when the user writes something in the combobox I want to have it in a Lostfocus manner and when he makes the selection from the dropdown of combobox I want to have it in a PropertyChanged manner.
Let me know if more details are required.
I removed the "IsTextSearchEnabled" property but it also didnt work then I came to know that "IsTextSearchEnabled" property of Comobobox is by default true, which is causing some values suggested by the combobox are setting in my properties. As soon as I made the "IsTextSearchEnabled" to false, it is working fine.
I have a telerik's radcombobox like below:
<telerik:RadComboBox x:Name="cbCustomerName"
Grid.Row="1"
Grid.Column="1"
Grid.ColumnSpan="3"
Margin="0 0 0 10"
DisplayMemberPath="FullName"
IsEditable="True"
IsFilteringEnabled="True"
ItemsSource="{Binding Customers}"
OpenDropDownOnFocus="True"
SelectedValuePath="CustomerId"
SelectionChanged="cbCustomerName_SelectionChanged"
Text="{Binding CurrentCustomer.FullName,
UpdateSourceTrigger=LostFocus}" />
When I type something in the textbox that is not in its items list and then go to some other control, it clears the text in it, which I don't want.
I have checked all properties and couldn't find anything to retain it after losing focus.
Please help if anyone knows about this.
I know this question is old but I figured I'd post a solution in case anyone else has this issue. If you set the "IsTextSearchEnabled" property to "False", it allows custom text and doesn't clear it when the RadComboBox loses focus.
Have you tried using the AllowCustomText Property to true?
Try adding TextSearchMode="Contains". Either that or try removing IsFilteringEnabled="True" if you do not need to filter your results.
I am not 100% sure, but it may clear your text if you try and filter it and it does not find anything.
Here's my code snippet :
<TextBox Text="{Binding Path=Amount, Mode=TwoWay, StringFormat=\{0:N\}}" />
If the user enters letters or a large number etc, the stringformat dies silently. How can i raise an exception instead ?
Thanks
Bindings swallow exceptions thrown when text input cannot be converted to the data type required by the property on source object. However you can specify ValidatesOnException in the binding. That will cause the standard red border reporting of a conversion problem. BTW this is unrelated to the string format property which is only relevant for displaying the current value, it isn't in play when user is entering data.
<TextBox Text="{Binding Path=Amount, Mode=TwoWay, StringFormat=\{0:N\}, ValidatesOnExceptions=True}" HorizontalAlignment="Left" Width="200"/>
Note I've limited the width and aligned to left. One of the problems with the default validation popup is that is that it is always displayed to the right, which is a bit of a problem when the text box right border is flush with the right edge of the silverlight control's right edge.
Have you thought of writing a filter behavior that allows you to control exactly what goes into the text box?
As the title states, I have a usercontrol with a textbox inside. The purpose of the user control is to add a spell check button and character count below the textbox. But for the most part, I'm using it just like a normal textbox:
<controls:SuperTextBox Text="{Binding Accomplishments, Mode=TwoWay, ValidatesOnNotifyDataErrors=True,NotifyOnValidationError=True}"
Height="200" EnableCharacterCounting="True" EnableSpellChecking="True" AcceptsReturn="True"
TextWrapping="Wrap" />
The problem I'm having is that I no longer get the nice red border when validation fails for the field. What do I need to do to reenable that behavior?
What you need to do here, it's to relay the validation of your UserControl back to the textbox.
I did answer a similar question here.
