<igdp:unboundfield width="1*" label="{loctext props:resources.grouplist_sync}" bindingmode="twoway"  bindingpath="issynchronise.value" converter="{staticresource booltoumdirectoryfilter}" converterparameter="enabled"  tooltip="{loctext props:resources.grouplist_sync}">     <igdp:unboundfield.settings>         <igdp:fieldsettings allowedit="true">             <igdp:fieldsettings.labelpresenterstyle >                 <style  targettype="igdp:labelpresenter"  basedon="{staticresource gmslabelstyle }">                     <setter property="automationproperties.automationid" value="group_sync"></setter>                 </style>             </igdp:fieldsettings.labelpresenterstyle>             <igdp:fieldsettings.cellvaluepresenterstyle>                 <style targettype="{x:type igdp:cellvaluepresenter}">                     <setter property="margin" value="2"></setter>                     <setter property="template">                         <setter.value>                             <controltemplate targettype="igdp:cellvaluepresenter">                                 <checkbox name="chksynchronise"  ischecked="{binding path=datacontext.dataitem.issynchronise.value,  relativesource={ relativesource mode=templatedparent}}"                                               horizontalalignment="center"  command="{binding synchronisegroups,relativesource={relativesource mode=self}}" horizontalcontentalignment="left" >                                  </checkbox>                                 <!--<checkbox ischecked="{binding path=datacontext.dataitem.issynchronise.value, mode=twoway,updatesourcetrigger=propertychanged, relativesource={ relativesource mode=templatedparent}}"                                                              command="{binding synchronisegroups,relativesource={relativesource mode=self}}"                                                           horizontalalignment="center" horizontalcontentalignment="left"  >                                  </checkbox>-->                             </controltemplate>                         </setter.value>                     </setter>                 </style>             </igdp:fieldsettings.cellvaluepresenterstyle>         </igdp:fieldsettings>     </igdp:unboundfield.settings> </igdp:unboundfield>

so, how should bind command checkbox in order work click , behaviour of checked , unchecked inside viewmodel? appreciated. in advance.

at first want add side note: since infragistics release 14.2 unbound field obsolete (look here).

for binding boolean xamdatagrid prefer using checkboxfield.

class: 

public class yourclass : notificationobject {     private bool _checkboxvalue;      public bool checkboxvalue     {                 {             return this._checkboxvalue;         }          set         {             if (this._checkboxvalue != value)             {                 this._checkboxvalue = value;                  // something: event, method, ...                  this.raisepropertychanged(nameof(this.checkboxvalue));             }         }     } }

xaml:

 <igdp:fieldlayout>      <igdp:checkboxfield bindingtype="usealternatebinding"                          name="checkerfield"                          label="yourcheckerfieldlabel"                          tooltip="yourtooltip"                          alternatebinding="{binding checkboxvalue, mode=twoway, updatesourcetrigger=propertychanged}"                          />  </igdp:fieldlayout>
