asp.net - Button in ItemTemplate of RadListView is losing its disabled property after PageChange -


i have radlistview control, has asp button in itemtemplate delete item . have requirement make controls in page read only. intially in page_prerender event traversing through controls , child controls , disabling them. working expected. when change page of radlistview asp controls have disabled them earlier again getting enabled. expected behaviour radlistview combining radpager. below properties have set. 

<telerik:radajaxmanagerproxy id="adcleintsradajaxmanagerproxy" runat="server">         <ajaxsettings>             <telerik:ajaxsetting ajaxcontrolid="clientsradajaxpanel">                 <updatedcontrols>                     <telerik:ajaxupdatedcontrol controlid="clientsradlistview" />                 </updatedcontrols>             </telerik:ajaxsetting>         </ajaxsettings>         </telerik:radajaxmanagerproxy>    <telerik:radajaxpanel id="clientsradajaxpanel" runat="server"                loadingpanelid="radajaxaloadingpanel" viewstatemode="disabled">              <telerik:radlistview id="clientsradlistview" runat="server"                 itemplaceholderid="drugscontainer"                  allowpaging="true" pagesize="4" datasourceid="clientsdatasource"                   onitemdatabound="clientsradlistview_onitemdatabound"                 viewstatemode="disabled" onneeddatasource="clientsradlistview_onneeddatasource"  onitemcreated="radlistview1_itemcreated" >

i have checked button enable property in different events when changed page. below sequence of page flow.

when changed radlistview page>

radlistview1_itemcreated> button.enabled property true

pageload > button.enabled property true

page_prerender > first disabling form elements function > found button enabled property false here after disabling means function working fine.

radlistview1_itemcreated> event fired again , button.enabled true here. please can 1 me this?

try using onitemdatabound event of listview set control properties in it.

page_prerender may tad late , viewstate may not updated (which may expected because disabled viewstate listview, don't know expect , after)

or, if explicitly set enabled property true in itemcreated event of listview, behavior expected, not sure doing, code not provided.

also, replace clientsradajaxpanel asp:panel. radajaxmanager/radajaxmanagerproxy must not ajax-enable radajaxpanel.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
