wpf - Find Editor inside Active cell (XamDataGrid) infragistics -

how find cellvaluepresenter based on activerecord or activecell in infragistics xamdatagrid?

i tried below code giving null in cell value presenter.

    private void grdgrid_recordactivated(object sender,recordactivatedeventargs e)     {              (grdgrid.activerecord datarecord).cells["flddescription"].isactive = true;              cell selectedcell = grdgrid.activecell;              cellvaluepresenter cvp = cellvaluepresenter.fromcell(selectedcell);              cvp.editor.starteditmode();  }

this binding 

<igdp:unboundfield  name="flddescription" label="description" bindingpath="taskitemaction.description" bindingmode="twoway">                                                             <igdp:field.settings>                                                                 <igdp:fieldsettings cellclickaction="entereditmodeifallowed" editorstyle="{staticresource textstylekey}" editortype="{x:type editors:xamtexteditor}" editastype="{x:type sys:string}"                                                          cellwidth="30" cellheight="30" allowedit="true" width="0.4*" height="30" >                                                                  </igdp:fieldsettings>                                                             </igdp:field.settings>

so want find activated record event , find editor type , start edit mode.

    private void grdtaskitemaction_recordactivated(object sender, recordactivatedeventargs e)             {     grdgrid.executecommand(datapresentercommands.starteditmode); }

is working fine me calling edit mode cell not editor(control inside it).

i want find editor inside activated cell , make start editable type.

you can directly cell using activerecord.

 private void grdgrid_recordactivated(object sender, infragistics.windows.datapresenter.events.recordactivatedeventargs e)     {         cell selectedcell = (grdgrid.activerecord datarecord).cells["flddescription"];          cellvaluepresenter cvp = cellvaluepresenter.fromcell(selectedcell);          cvp.editor.starteditmode();     }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
