Anyone know if the scheduler can format like this?

Hi,

I've been researching the scheduler and can't seem to see if I can get the scheduler to format Data like the below

Person Monday 25th Tuesday 26th Wednesday 27th Thursday 28th etc

Jamie

Chris

Fred

Steve

Basically I want day slots for each person that I can schedule tasks for. Only one box is required for the task (we can combine multiple tasks into one if necessary) However if its possible to add multiple tasks to the one box that is even better (for drag and dropping tasks between people / days)

Any assistance greatly appreciated or advice on another control that might be better suited.

[Solved] Cannot populate datasource

I have a grid that I want to populate from data returned from an ajax request.

The data is returned as part of the Ajax response, but is not displayed in the grid.

My code is:-

$.ajax({

type: "POST",

async: true,

contentType: "application/json;charset=utf-8",

url: "@Url.Content("~/Dynamic/CompareTables")",

data:'{"tab1":"' + t1 + '","tab2":"' + t2 + '","link1":"' + l1 + '","link2":"' + l2 + '","CompDesc":"' + desc + '"}',

dataType: "json",

success: function (data) {

if (data.Success == true) {

alert(data.Message);

//Create grid from data

var fMatches = new kendo.data.DataSource({ data: data.FieldMatches });

fMatches.read();

$("#fieldCompGrid").kendoGrid({

dataSource: {

data: fMatches,

schema: {

model: {

fields: {

FieldName: { type: "string" },

FieldTypeMatch: { type: "boolean" },

MatchFound: { type: "boolean" },

MaxLengthMatch: { type: "boolean" },

PrecisionMatch: { type: "boolean" },

OutputHeader: { type: "string" },

Output: { type: "string" },

CanBeCompared: { type: "boolean" }

}

},

pageSize: 20

},

height: 550,

scrollable: true,

sortable: true,

filterable: true,

pageable: {

input: true,

numeric: false

},

columns: [

"FieldName",

{ field: "FieldTypeMatch", title: "Type Match" },

{ field: "MaxLengthMatch", title: "Max Length Match", width: "130px" },

{ field: "CanBeCompared", title: "Can Be Compared" }

]

});

//show div

$('#resultsDiv').show();

//$("#Grid").data("kendoGrid").dataSource.read();

$('#compBtn').show();

$('#imgWait').hide();

}

else {

$('#imgWait').hide();

alert(data.Error);

$('#compBtn').show();

}

,

error: function () {

$('#imgWait').hide();

alert("An error has occurred.");

$('#compBtn').show();

}

});

How can I get this working?

Thanks

DropDownList with value bound to property not showing item when datasource is refreshed.

Hi,

I'm having a problem with a dropdownlist not showing the item that is returned when datasource is refreshed. It can be tested to see what I mean in the following dojo sample. Can anyone point me in the right direction on how to get the dropdownlist to show the returned item when the "Click me" button is returned.

Selecting a specific drawer in the Drawer component

Hi

I have implemented the new Drawer component:

$("#drawer").kendoDrawer({

template: tooltemplate,

mode: "push",

mini: true,

itemClick: function (e) {

e.sender.drawerContainer.find("#drawer-content > div").addClass("hidden");

e.sender.drawerContainer.find("#drawer-content").find("#" + e.item.find(".k-drawer-id").text()).removeClass("hidden");

var spanItemText = e.item.find(".k-item-text").html();

$('#titleSpan').html(spanItemText);

},

position: 'left',

minHeight: 800,

swipeToOpen: false

});

All is great. The Drawer component functions perfectly. Whenever it is used it always defaults to the top (first) drawer. My users now want the ability to specify which drawer is selected by default. I've implemented a my settings page where the user can specify which drawer they prefer as their default. This value (which is the spanItemText value in my code above) is stored in a cookie. How do I select this drawer each time the component is used. Or is there a better way of doing this? I'm trying to programmatically click the drawer icon but I'm not having much luck at the moment.

Thanks.

non-grid pager problem

Hope this is the right forum, there isn't one for "pager".

We have a datasource that is associated with a pager object - directly, not via a grid.

This worked fine in 2019/1 but when we updated to 2019/3 it stopped working - rather than having a list of page numbers left-to-right along the bottom, we just have a single page number with a dropdown menu associated with it.

This dojo illustrates:

https://dojo.telerik.com/IYolIKoL

Adding the setting

responsive: false

fixes the issue.

Is this an intended change in behaviour? I can't see it documented anywhere, and we don't get the same thing happening if the pager is associated with a grid rather than a datastore.

[Solved] Kendo Grid not calling server when calling read

So I am working in ASP.NET MVC using a Kendo Grid and I am having trouble with the grid not reloading after calling read. There isn't an error in the console and the grid just goes blank. At first I thought it was because it was editable but then i removed that and it still has issues.

[Solved] pushUpdate fails for Grid DataSource

Hi,

Im using a grid to display near real-time data from c#/ASP.Net server side via SignalR - adding/updating data rows with pushUpdate().

I already have one grid working in this manner but I haven't been able to work out why updates to a new grid are failing with the error:

TypeError: target.accept is not a function

at init.pushUpdate (kendo.all.js:6765)

In the following line (kendo.all.js:6762) - I noticed that model.id was undefined:

var target = this.get(model.id);

I have replicated this on dojo. It appears the grid/datasource doesn't handle the initial data, then does reflect the first update, but not the second.

On my machine, I'm using the following:

Simply setting a cell value

I have a grid with 5 columns - COL1 to COL5. I call a function when the user selects a row and chooses a menu option from a context menu. The function gets the selected row. All I want to do is set the text of a certain column in the selected row:

var grd = $(gridCTL).data('kendoGrid');
var selectedItem = grd.dataItem(grd.select());

selectedItem.COL1 = "new value"; // this does not work

Can anyone help with this simple task ?!

Loading an Item greater than the dataSource's PageSize

I have a kendoComboBox, with an associated dataSource that has more items than the PageSize. This comboBox is bound to one my columns in the grid. When creating a new record, i can access the items for this comboBox, that are not in the first 'pageSize items', by using the comboBox's filter and suggestion features, so i start typing, and can access a previously unloaded item. My problem occurs after i have created a record, and selected an item in this comboBox, that was not loaded at first on the dataSource, that is, an item greater than the PageSize. When i open the popup, and try to edit such a record, the comboBox is unable to find the previously selected item and, only displays the item's value field, instead of it's text field. From what I understand, because the item is not loaded in the dataSource by default, since it is greater than the PageSize, the comboBox's dataSource is unable to find the dataItem an assign it to the comboBox. So, what i would like to know, is if there is a way to load items that are larger than the dataSource's pageSize, when editing a record that already has these items selected on their comboBoxes.
