c# - Select whole column by clicking ColumnHeader. WPF DATAGRID -

-

i have data grid has disabled sorting. want achieve - clicking column header want select cells in column(select whole column). i've added eventsetter datagridcolumnheader bind method click event, have no idea how method should written. ideas?

my code:

private void columnheaderclick(object sender, routedeventargs e) {         var columnheader = sender datagridcolumnheader;         if (columnheader != null)         {             if (dgdane.selectedcells != null)             {                 dgdane.selectedcells.clear();             }             foreach (var item in dgdane.items)             {                 dgdane.selectedcells.add(new datagridcellinfo(item, columnheader.column));                               }             dgdane.focus();         }     }

i edited code, 1 above works fine(thanks @nit). i've added focus datagrid because necessary.

this should trick

private void columnheaderclick(object sender, routedeventargs e)     {         var columnheader = sender datagridcolumnheader;         if (columnheader != null)         {             datagrid.selectedcells.clear();             foreach (var item in datagrid.items)             {                 datagrid.selectedcells.add(new datagridcellinfo(item,columnheader.column));             }         }     }

make sure set selectionunit="cell" on datagrid

<datagrid x:name="datagrid" autogeneratecolumns="false" issynchronizedwithcurrentitem="true"             selectionunit="cell" />

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
