i working componentone wpf controls mvvm pattern.
i have following in viewmodel:
public icommand clientsenter { { if (this.m_clientsenter == null) { this.m_clientsenter = new delegatecommand<string>(clientslostfocusexecute, clientslostfocuscanexecute); } return m_clientsenter; } } and observable collection:
public observablecollection<client> clients { { return m_clients; } set { m_clients = value; raisepropertychanged("clients"); } } in xaml have added componentone combo box can enter clientname or id , press enter fire event execute clientsenter command:
<custom1:c1combobox grid.row="2" grid.column="1" height="24" name="cmbclients" horizontalalignment="left" verticalalignment="center" itemssource="{binding clients, mode=oneway}" selectedvaluepath="clientid" displaymemberpath="namee" iseditable="true" text="enter client name or id" selectedvalue="{binding path=filter.clientid, mode=twoway}" minwidth="150" margin="0,2" width="189"> <i:interaction.triggers> <ei:keytrigger key="enter" firedon="keyup" activeonfocus="true" sourcename= "cmbclients"> <i:invokecommandaction command="{binding clientsenter, mode=oneway}" commandparameter="{binding text,elementname=cmbclients}" commandname="keydown"/> </ei:keytrigger> </i:interaction.triggers> </custom1:c1combobox> i need know why doesn't work, after pressing enter clientid disappears , nothing happens. text="enter client name or id" doesn't appear! ideas? note when change key space works doesnt take text combobox,
after spending 2 days investigating issue ,i discover there bug in c1combobox replaced telerik comboxbox , add same trigger without changing in xaml except control , works fine.
finally,i dont recommend c1 wpf controls
