javascript - Kendo UI Default Grid Filter value -


i trying default kendo ui grid filtered on page load. have column boolean values need display ones "false" on page load allow user see them if clear filters.

example: http://www.telerik.com/forums/adding-filters-to-grid-s-source 

    function updatesearchfilters(grid, field, operator, value) {         var newfilter = { field: field, operator: operator, value: value };         var datasource = grid.data("kendogrid").datasource;         var filters = null;         if ( datasource.filter() != null){             filters = datasource.filter().filters;         }                if ( filters == null ) {             filters = [newfilter];         }         else {             var isnew = true;             var index = 0;             for(index=0; index < filters.length; index++) {                 if (filters[index].field == field) {                     isnew = false;                     break;                 }             }             if ( isnew){                 filters.push(newfilter);             }             else {                 filters[index] = newfilter;             }         }         datasource.filter(filters);     }

i have tried solution call function on databound event when user clears filter , tries group or set other filters, filter reappears. using razor syntax in view , hoping there set there.

update: time being, have wrapped example function in if on class level variable set true/false based on if has been called before feel primitive solution.

    function ondatabind(grid, field, operator, value){         if(!alreadyfiltered) //class level variable set true after datasource.filter(filters);             updatesearchfilters(grid, field, operator, value);         }     }

updating initial comment answer. essentially, if define datasource filter, define datasource in initial state , user still able change filter using ui/controls normal.

for javascript implementation, might this:

datasource: {     // ... other config     filter: { field: "yourcolumn", operator: "equals", value: false } }

if using column menu filtering, filter show user change - have defined initial state.

you mentioned using mvc implementation. haven't used helpers before. expect matter of using similar configuration method, point, documentation doesn't seem clear. start here:

http://docs.telerik.com/aspnet-mvc/helpers/grid/configuration#filter

so, maybe ends looking this:

.datasource(datasource => datasource                 .filter(filters =>     {                filters.add(f => f.yourcolumn).equals(false);     }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)
