c# - Dynamically hide a row in a DataGrid -

-

i want hide 1 row of datagrid when user selects row.

how can that?

 private void datagridcommands_selectionchanged(object sender, selectionchangedeventargs e)  {      (int = 0; < datagriddata.items.count; i++)      {          if ((datagriddata.items[i] datafortable).msgtype ==   _qf.elementat(datagridcommands.selectedindex).mcode)          {              //need hide 1 row datagriddata          }      }  }

i not know logic want use hidding row datagrid, show simple sample.

the point need retrive container of row , hide it. let's see how. xaml:

<stackpanel>     <datagrid autogeneratecolumns="true" canuseraddrows="false"                 selectionchanged="datagrid_selectionchanged" name="datagrid" /> </stackpanel>

and code-behind:

public partial class window3 : window {     private observablecollection<person> people = new observablecollection<person>();      public window3()     {         initializecomponent();          people.add(new person() { name = "paul", surname = "green" });         people.add(new person() { name = "mike", surname = "gray" });         people.add(new person() { name = "john", surname = "black" });          datagrid.itemssource = people;     }      private void datagrid_selectionchanged(object sender, selectionchangedeventargs e)     {         datagridrow datagridrow;         foreach (person p in e.addeditems)         {             if (p.name == "mike")             {                 datagridrow = datagrid.itemcontainergenerator.containerfromitem(people[2]) datagridrow;                 datagridrow.visibility = system.windows.visibility.collapsed;                 return;             }         }          datagridrow = datagrid.itemcontainergenerator.containerfromitem(people[2]) datagridrow;         datagridrow.visibility = system.windows.visibility.visible;     } }

my logic want hide last person object in collection if user select person named "mike". retrieve container (a datagridrow in case) correspond row want hide/show. set visibility right value.

i hope sample can give hint issue.
