                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

as you see there are some styles for Texts or ComboBox but there is no style for buttons. How can I add buttons to each row and set the specific button style?

Answer 1

First part of your question

How to add a button for each row in a Wpf datagrid ?

That's how you add a button foreach row in a WPF DataGrid.

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="BtnClicked">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>  

So, you create a DataGridTemplateColumn and inside that you define DataTemplate and Inside that you can set Button or any other UI Element you want to show for each row e.g a CheckBox.

Now, Coming to second part of your question.

How to add a particular style to it ?

Well you can define style for this button like any other button you do or you can assign it a Style resource or template. Something like below,

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="BtnClicked" Background="White" Foreground="Black" BorderThickness="2" BorderColor="Black">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>  

Or assign a style resource.

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="BtnClicked" Style="MyBtnStyle">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>
