c# - Open groups and details in Devexpress Grid view by Name -

i'm developing winform application contains devexpress gridview composed follow:

• hotel view (grouped location , hotel name column)
• availability view (is detailed view of hotel grid , contains availability selected hotel)

i have data in input: location name, hotel name.

when open form need expand corresponding group location , hotel name , open detail view availability hotel.

in attachment can find screenshot of grid row expanded need.

can me that?

the code have tried following, opens location group , not hotel name , it's details.

private void hotelavailabilitygridview_endgrouping(object sender, eventargs e) {     focusfirstrecordingrouprow(_hotelname); }  public void focusfirstrecordingrouprow(string texttofind) {     int grouprow = findgrouprow(_hotelname);     if (grouprow >= 0) return;     hotelgridview.expandgrouprow(grouprow);     hotelgridview.focusedrowhandle = hotelgridview.getchildrowhandle(grouprow, 0); }  private int findgrouprow(string texttofind) {     int = 1;     while (i != gridcontrol.invalidrowhandle)     {         i--;         string value = hotelgridview.getgrouprowvalue(i, hotelgridview.columns[0]).tostring();         if (value == texttofind)         {             recursexpand(hotelgridview, i);             return i;         }     }     return 0; } 

the screenshot:

i suggest go through documentation of process group rows

you can check whether group row using below method of view:

int rowhandle = view.focusedrowhandle; if(view.isgrouprow(rowhandle)){} 

after that, can set expands status:

bool expanded = view.getrowexpanded(rowhandle); view.setrowexpanded(rowhandle, !expanded); 

you can locate row value below, can expand matched row , collapse others require.

using devexpress.xtragrid.views.grid; //...  gridview view = gridview1; int rowhandle = -1; {     rowhandle = view.locatebyvalue(rowhandle+1, view.columns["is in stock"], false);     view.makerowvisible(rowhandle, false); } while(rowhandle != gridcontrol.invalidrowhandle);
