Change formatting of Grid column in response to event

Hello,
I have a Kendo Grid (called 'overallGrid' in my example) with some columns formatted as percentages with one decimal place ( format: "{0:p1}" ). I also have a View Model with a Select element, where the user can change what values they wish to see in the columns. What I need to do is, when they pick a certain option in the Select element, the formatting of the columns should be changed to be a decimal with 1 decimal place, rather than a percentage.

At the moment, I have this in the "click" event of a "update grid" button;

if (viewModel.score == 'Mean') {

overallGrid.columns[1].format = '{0:n1}';

overallGrid.columns[3].format = '{0:n1}';

}

overallGrid.dataSource.filter( [

{ field: "score", operator: "eq", value:viewModel.score},

]);

overallGrid.dataSource.read();

overallGrid.refresh();

When run, the formatting on the rendered grid does not change, even though I can see that the "columns.formatting" of the Grid object has been changed when I inspect the object in Firebug.

What am I doing wrong? Thanks!

Fetch vs. Read

The documentation is not clear on the differences between dataSource.fetch() and dataSource.read(). Can you explain the differences?

create fire multiple request

Hello!

I have a problem while creating more than one object in a grid. Creating the first object is okay. But when I save the second object it send the request to the server and saves it (it returns a json object with the required ID) but a second request with previous data is fired too. How can i avoid that?

The "batch" flag in DataSource is set to false.
(Version: Kendo UI Complete v2013.1.614)

Thank you in advance.

app.navigate in MVC

I have been searching for how to do this, but am unable to find the right answer.

In JavaScript I can do this:

var app = new kendo.mobile.Application();

Then use the app variable to navigate between pages.

But how do I do this in MVC? I can't set the MVC razor tag to a JavaScript variable, so how do I call .navigate after doing:

@(Html.Kendo().MobileApplication()
.Name("KendoMobileApplication")
.PushState(true)
.Transition("slide")
.ServerNavigation(false)
.Layout("databinding")
)

I have tried this, but it seems less than ideal that I create a new application every time I navigate:

var app = new kendo.mobile.Application();
app.navigate("/Home/AccountType");

I've also tried

$("#KendoMobileApplication").context.navigate("/Home/AccountType");

But that doesn't work. It has no navigate method.

So what is the correct way of doing this?

Application

custom validation for a custom editor (kendoDropDown) in a kendoGrid

Hey,

In one of those columns I have a custom editor in the form of a dropdown list. The first value of the list is "Please select a function" with value 0.
When the user creates a row and does not select a function it should give an error. The function field is required and I want validation on it.

I have it "working" but I think that this is not the way it should be. And however it works I still can't add z-index or any style to my tooltip because the syle get overriden when the message is shown in the grid.

The code is:

001.<script id="tooltip" type="text/x-kendo-template"> //Custom Tooltip created by me

002. <div class="k-widget k-tooltip k-tooltip-validation k-invalid-msg" data-for="#= Key #" role="alert">

003. <span class="k-icon k-warning"> </span>

004. #= Message #

005. <div class="k-callout k-callout-n"></div>

006. </div>

007. </script>

008. <script>

009. var tooltip = new kendo.template($("#tooltip").html());

010.

011. $(document).ready(function () {

012. $("#grid").kendoGrid({

013. dataSource: new kendo.data.DataSource({

014. transport: {

015. create: {

016. url: "/Beheer/Medewerker/CreateJson",

017. type: "POST",

018. dataType: "json"

019. },

020. read: {

129. editor: "<input name='Actief' type='checkbox' data-bind='checked: Actief' #= Actief ? checked='checked' : '' # />",

130. width: 70

131. },

132. {

133. command: [{ name: "edit", text: "Wijzig" }, { name: "destroy", text: "Verwijder" }]

134. }

135. ]

136. });

137. });

138.

139. function FunctieDropDownEditor(container, options) {

140. $('<input data-text-field="Naam" data-value-field="Id" name="sl' + options.field + '" data-bind="value:' + options.field + '" />')

141. .appendTo(container)

142. .kendoDropDownList({

143. autoBind: false,

144. dataSource: {

145. type: "json",

146. transport: {

147. read: "/Beheer/Functie/ListJson",

148. }

149. }

150. });

151. }

152.

153. function AfdelingDropDownEditor(container, options) {

154. $('<input data-text-field="Naam" data-value-field="Id" name="sl' + options.field + '" data-bind="value:' + options.field + '" />')

155. .appendTo(container)

156. .kendoDropDownList({

157. autoBind: false,

158. dataSource: {

159. type: "json",

160. transport: {

161. read: "/Beheer/Afdeling/ListJson",

162. }

163. }

164. });

165. }

166. </script>

Is there a simple way to create validation rules + error messages for a custom editor, like in this case a dropdownlist.
I want an "error" message if a user does not select a function or he/she selects the first value (which is "Please select a function" with value 0).

Thanks,

Jeroen

Problem with finding open window (duplicate dom elements?)

I am declaring a window like this...

in my html
<div id='mywin'></div>

in my js file...
var window = $('#mywin');
if (!window.data("kendoWindow")) {
window.kendoWindow({
width: winWidth + "px",
height: winHeight + "px",
minWidth: winWidth + "px",
minHeight: winHeight + "px",
title: "Place of Interest Search",
actions: ["Close"],
resizable: false
});
}

//open identify window
window.data("kendoWindow").center();
window.data("kendoWindow").open();

this all works but when i attempt to reload content by...

if ($("#mywin").data("kendoWindow")) {

..reload logic here

this ("#mywin").data("kendoWindow") always returns false thus recreating the window every time.

I notice in the dom there is the original div and then a duplicate div for the window at the bottom of the dom with the same id (mywin)

what am i doing wrong here? I want to reuse the original window without having to destroy it and recreate it.
