c# - How to add item in DataGrid (smart way) -

actually read lot of solution long. there no way make this:

datagrid.items.add("element"); 

?

since you're using wpf, you'll want create list use datagrid.itemssource = yourclasstoshowlist;. auto populate columns , row items you. upon event selecteditemchanged can grab single (or multiple) selected youclasstoshow's. wpf make simple bind data ui controls.

here examples:

xaml

<datagrid x:name="dg" margin="10,32,10,111" alternatingrowbackground="white" selectionchanged="dgdailymediareport_selectionchanged" isreadonly="true" autogeneratecolumns="false" selectionmode="single" >     <datagrid.columns>         <datagridtemplatecolumn header="{binding status}" width="75">             <datagridtemplatecolumn.celltemplate>                 <datatemplate>                     <grid>                         <progressbar  height="20"  grid.row="0" grid.column="0" minimum="0" maximum="500" value="{binding totalprogress, mode=oneway}"></progressbar>                         <label horizontalalignment="center" content="{binding totalpercent,mode=oneway}"></label>                     </grid>                 </datatemplate>             </datagridtemplatecolumn.celltemplate>         </datagridtemplatecolumn>         <datagridtextcolumn header="name" binding="{binding name}" foreground="darkred" />         <datagridtextcolumn header="age" binding="{binding age}" />      </datagrid.columns>      <datagrid.contextmenu>         <contextmenu>             <menuitem x:name="menushowinfolder" header="show in folder" click="menushowinfolder_click"/>         </contextmenu>     </datagrid.contextmenu> </datagrid> 

c#

window_loaded event:

list<yourclass> yourclasslist = yourclasslistrepo.getyourclasses(); dg.itemssource = yourclasslist; 

dg_selectionchanged event:

if(dg.selecteditems.count > 0){     foreach(yourclass yourclass in (list<yourclass> dg.selecteditems)){         messagebox.show(yourclass.name);     } } 

binding="{binding name}" "name" in context objects public property.

so you'll need public access method public string name {get;set}

side note: change object's property value , have auto show, you'll need inotifypropertychanged on object itself:

person class:

public class person: inotifypropertychanged {     #region property_changed_events     public event propertychangedeventhandler propertychanged;     protected virtual void onpropertychanged(string propertyname)     {         propertychangedeventhandler handler = propertychanged;         if (handler != null) handler(this, new propertychangedeventargs(propertyname));     }     protected bool setfield<t>(ref t field, t value, string propertyname)     {         if (equalitycomparer<t>.default.equals(field, value)) return false;         field = value;         onpropertychanged(propertyname);         return true;     }     #endregion      private string _name;     public string name { { return _name; } set { setfield(ref _name, value, "name"); } } }
