Hello,

I am trying to do the following: I copy some data from one TreeView to another They share a DataSource and essentially all I do is set value A to value B, while TreeView1 displays A and TreeView2 displays B.

My steps are:

1) I expand all nodes (loadOnDemand is true so the initial page load doesn't take too long).

2) After the expand is done I copy said data and

3) update the treeView by using node.load() 

(as recommended in this older thread: https://www.telerik.com/forums/force-reload-of-child-nodes#QqLTmHiNQkGQTnhxA2hLSA)

Now, this is working as expected, but as soon as the DataSource gets a bit bigger it gets really slow. My test Data has about 200 items in 3 layers and in IE it takes about 50s for the "node.load()" alone to finish. (Chrome is a lot better with about 5s, but unfortunately I have to use IE.)

I tried a lot of other ways to refresh or reload the TreeViews, but sadly nothing worked for me. I can't read the DataSource again, since my edits are only client-side at this point. A setDataSource() made no changes, as well as simply setting the DataSource (not that the last one is unexpected, but I was getting desperate...)

Does anyone here have a solution for me? Maybe I'm missing something really obvious?

Thanks!

Hello. I'm been dealing with a problem when using conditional formatting. I've created a dojo to explain my problem.

https://dojo.telerik.com/UNoCUfiL/2

TL;DR of my problem: I have to use this format: "[<-10][RED]##,##0.00\%;[>10][RED]##,##0.00\%;##,##0.00\%". Everytime my cell value is < 10 ([<-10][RED]) or > 10 ([>10][RED]), it loses the negative sign. I can't write any rule based on the value 10, because it will change programmatically.. I'm just giving an example with the value 10.

Thank you!

Have a Grid.cshtml page which has one dropdown which is defined by a EditorTemplateName named ValueViewTemplate.cshtml (below).... Would like to add more dropdowns to the Grid.cshmtl.  Currently seems like have to add more EditorTemplateName templates for each dropdown.  Is there way to pass in the ViewData to the EditorTemplateName function so don't have to define a editor template for each dropdown?

Also current pages seems to work for InCell and InLine... Is there way to make it work for Popup for does there need to be additional templates defined for the Popup option for editable mode...

Grid.cshtml

@(Html.Kendo().Grid<NEP_Deconstruction.Data.Models.ApprovalViewModel>()
                .Name("approval_grid")
                .Columns(columns =>
                {
                    columns.Bound(o => o.ApprovalNumber);
                    columns.Bound(o => o.ApprovalName);
                    columns.Bound(o => o.Comment);
                    columns.ForeignKey(o => o.ApprovalCountryID, (System.Collections.IEnumerable)ViewData["ApprovalCountry"], "ID", "Value")
                    .EditorTemplateName("ValueViewTemplate");
                    columns.Bound(o => o.EffectiveDate);
                    columns.Command(command => { command.Edit(); command.Destroy(); }).Width(210);
                })

                .ToolBar(toolbar => toolbar.Create())
                .Editable(editable => editable.Mode(GridEditMode.InLine))

ValueViewTemplate.cshtml

@model NEP_Deconstruction.Data.Models.ValueViewModel

@(Html.Kendo().DropDownListFor(m => m)
                .DataValueField("ID")
                .DataTextField("Value")
                .BindTo((System.Collections.IEnumerable)ViewData["ApprovalCountry"])
)

Is there a way to cancel the changes of one field in one item in the DataSource?

Let us say that the user is modifying in the grid one item and he wants to cancel the changes of this item (one specific field) and not all his changes in the grid, can this be done?

Hi.

I have a few search fileds (text, kendoDropDownList, kendoMultiSelect) just above my grid.

Each change of such a search field changes the dataSource.filter of the grid in my "change" function.

I have a problem with the combination of the filters.

For example:

choosing "a" as a "status" in the kendoDropDownList will bring all the records with status "a".

If after selecting "a" as a "status" I select "b" as a "type" in another kendoDropDownList I want to get

all the records with "status" "a" and "type" "b".

If after that I change the selection of "a" to "c" I want to get all the records with "status" "c" and "type" "b" 

(removing the filter of "status" "a" and adding the filter of "status" "c" and "type" "b")

If I create a new filter in the "change" function and do:

dataSource.filter(newFilter)

I lose the filters I had before.

If I do:

var base = dataSource.filter();

newFilter = {logic: "or", filters: [...]};

base.filters.push(newFilter);

dataSource.filter(base);

I could get something like "status = 'a' and status = 'b'", and that's not what I want..

I would be happy to get help with that.

Thanks,

Eli.

Hi,

I'm using a kendoTooltip control with the content.url configuration.

The problem is it takes a second or so to load the content, which is a long time when you're hovering over something frequently.

I'd like to know if it's possible to programatically load the content in the background (say, a few seconds after the page loads). Then when the user hovers over the target control, the tooltip can display instantly (having already loaded the content).

Thanks,

George

Hello everyone,

I have a dynamic Kendo grid that can perform CRUD operations. Foreign Keys are retrieved and mapped to their value and placed in the grid as a drop down list using an editor template, similar to this example here: https://demos.telerik.com/kendo-ui/grid/foreignkeycolumn

I have virtualization enabled on those FK dropdowns similar to this example: https://demos.telerik.com/kendo-ui/dropdownlist/virtualization and my dropdown correctly calls the valueMapper with the id. The problem is with the valueMapper, as this function only receives the FK id or dataitem. I am not able to communicate to the server which column the FK id belongs to, and thus can not return the index of the value. This problem seems that it could result in any grid that has multiple foreign keys so I am hoping there is a solution but I have been unable to find one. Any tips/leads would be greatly appreciated!

Here is my DynamicForeignKey editor template that is used as in each FK column of the grid.
