Add Search button in TextBox

[delwooddsp5301]

Is there currently a way to add a Search button inside the MaterialDesignFilledTextBox? We have a custom style we created years ago to work with the standard TextBox. But we are now using the MaterialDesignFilledTextBox and would like to implement the same button. Wasn't sure if there was an existing way to do this or if we would have to do our own custom styling again.

@delwooddsp5301 unfortunately adding a search button inside any of the input controls is currently not supported.
I think your best bet at the moment is to copy the style of the TextBox into your project implement an additional button yourself.

An alternative (and quick & dirty solution) could look like the following:

<materialDesign:Card>
  <Grid>
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <TextBox Grid.Column="0"
             materialDesign:HintAssist.Hint="Search"
             Padding="8 0 0 0"
             FontSize="24"
             materialDesign:TextFieldAssist.DecorationVisibility="Hidden"/>
    <Button Grid.Column="1"
            Margin="8,0,0,0"
            Content="{materialDesign:PackIcon Kind=Search}"
            Style="{StaticResource MaterialDesignIconButton}"/>
  </Grid>
</materialDesign:Card>

There are multiple ways to implement such functionality:

1. A ContentPresenter and corresponding attached property like TextFieldAssist.AdditionalPrefixContent (and AdditionalSuffixContent) could be added to the template, so users can define any arbitrary content (probably my preferred solution)
2. I have seen libraries, which just make the "Prefix" or "Suffix" Icons clickable (essentially like a button)
3. Just hardcode a search button on either side of the textbox

@corvinsz thanks for the reply!! I was thinking about trying to make the Suffix icon clickable, will try that route
