How to set TextBox width Based on Border width dynamically in c#

Question

Hi,

   I am working on filled view. here I have a requirement as follows.

I have a TextBox which is inside a Border. here I am setting textbox width based on Border Width as follows in xaml.

<Border x:Name="TextBoxBorder" BorderThickness="0" Margin="0,0,5,0">
  <TextBox x:Name="InputDialBox" Style="{StaticResource AlcatelTextBoxStyle}" Width="{Binding ElementName=TextBoxBorder,  Path=ActualWidth}"  VerticalAlignment="Top" Height="Auto" Margin="0,0,0,0"/>
</Border>

I want to set width as above (Width="{Binding ElementName=TextBoxBorder,  Path=ActualWidth}") of textbox "InputDialBox" through  c# code.

can anyone suggest me best way to achieve the same.

Thanks in Advance.

Answer 1

I looked at this code and it seems to work fine.  If you don't put a width at all on the textbox, it should consume all of the available space (excluding margins, etc).  What is the real problem you're seeing with this?

If my reply answers your question, please mark this post as answered.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Hi Siddenki,

You can write below code in your xaml.cs file as

this.InputDialBox.Width = this.TextBoxBorder.ActualWidth

You can simply set the horizontal alignment property of the textbox to stretch. It will take all the horizontal space of the border.
