c# - Remove the default style of selected row -

I know that the question was asking a lot, but I've only seen Aksamel code file.
I'm working on a Datagrid extension, so I'm in C # code file and let me know how to remove the default style for the selected row (in my case I want to change nothing in style , I have an image

side question, what we have pressed "Ctrl" such a selection is and how C # code?

Thank you

< P> Edit

I try this code:

 < code> style oRow = new style (Taipf (Detagreedaro)); Detatrigr Otrigr 2 = new Detatrigr (); binding Obind = new Binding (); OBindkRelativeSource = new relative resource (Riletivssorsmodkfndanstor, Taipf (Datagreedaro), 1) ; OBind.Path = new Proprteepath (Detagreedrokaissclitproprti); Otrigr 2. binding = Obnd; OTrigger2.Value = true; OTrigger2kSetterskAdd (new setter (Detagreedarokbakgriproprti, Brskkhaki)); ORowkTriggerskAdd (OTrigger2); This.RowStyle = oRow;  
 
 For now, I tried to keep the selected background in Khaki for testing. But I get old blue highlights. 
 
  2 Edit  
 
 base on the idea of ​​Sinatr, I change the Detagrid Rao to Detagrid cell and ended up with: 
 
  style oRow = new style (typewrite (DataGridsel)); Datatrigger ostrigers 2 = new data triggers (); Binding Obid = new binding (); OBind.RelativeSource = New Relative Resource (RelativeSourceMode.FundAnstore, TypeGridRO, 1); OBind.Path = New Property Path (DataGridro.isSecurealtyProperty); Ootrigger 2 Binding = oblong; OTrigger2.Value = True; OTrigger2.Setters.Add (new setter (DataGridcel background background, empty)); OTrigger2.Setters.Add (new setter (DataGridCell.BorderBrushProperty, blank); ORow.Triggers.Add (oTrigger2); This.RowStyle = oRow;  
 
 I have to get the foreground of the line only to set the foreground of the cell. But I found a new question with that solution, it is okay to fix the background to clear or should I pair it in the background of the line? 
 

You have to change the CellStyle control template.

For example, this stupid templateing

  & lt; DataGrid x: name = "DataGrid" & gt; & Lt; DataGrid.CellStyle & gt; & Lt; Style TargetType = "DataGridCell" & gt; & Lt; Setter Estates = "Template" & gt; & Lt; Setter.Value & gt; & Lt; ControlTemplate TargetType = "DataGridCell" & gt; & Lt; Text block text = "1" background = "khaki" foreground = "red" /> & Lt; / ControlTemplate & gt; & Lt; /Setter.Value> & Lt; / Setter & gt; & Lt; / Style & gt; & Lt; /DataGrid.CellStyle> & Lt; / Data grid & gt;  

This will output the output (only 1 toggle> string, string, string> gt; , whatever):

It remains the same for selected or selected items.

Obviously you implement it properly, but when you answer, you should give an idea.
