Kendo UI Grid Angular - scroll to random row

Hi,
I am having a large grid and I have a random row(changed based on my require data) of the grid which is not a selected row.
But if the row is out of the viewport of the current view I would like to have the grid scroll down/up to the row, so the user can see the selected row automatically.
How do I accomplish in the angular grid?
Thanks for your help in advance.
Best regards

Saswat

Treeview arrow style

Hello,

I'm trying to create an UI just like Kendo jQuery Filter based on the Angular TreeView.

And I'd like to have lines other than the default arrows that represent the hierarchy like the screenshot.

How can I do this?

I created a stackblitz, and it would be greatly appreciated if could give me the solution based on this.

Dynamically adding a node

Hello,

I'm trying to dynamically add a child node to a treeview, but adding a child node to the selected dataitem does not refresh the treeview.

When I inspect the dataitem that I add a child node to, it has that child node.

Interestingly remove works fine.

I created a stackblitz, so that you can see the problem I'm having.

https://stackblitz.com/edit/angular-vqmryk?file=app%2Fapp.component.ts

Click the buttons I highlighted in the screenshot, and this will call onAddGroupClick() or onAddClick() where I'm adding a child node.

How can I make it so that the treeview understands that a node is added?

Below is the code.

import { Component } from "@angular/core";

@Component({

selector: "my-app",

template: `

<kendo-treeview

[nodes]="instructionJson.items"

textField="text"

kendoTreeViewExpandable

kendoTreeViewHierarchyBinding

childrenField="items"

[isExpanded]="isExpanded"

>

<ng-template kendoTreeViewNodeTemplate let-dataItem>

<ng-container *ngIf="dataItem.isHeader">

<kendo-buttongroup selection="single">

<button

kendoButton

[toggleable]="true"

(selectedChange)="

onOperatorSelectionChange($event, 'And', dataItem)

"

[primary]="dataItem.operator == 'And'"

>

And

</button>

<button

kendoButton

[toggleable]="true"

(selectedChange)="

onOperatorSelectionChange($event, 'Or', dataItem)

"

[primary]="dataItem.operator == 'Or'"

>

Or

</button>

</kendo-buttongroup>

<kendo-buttongroup>

<button

kendoButton

icon="k-icon k-i-filter-add-expression"

(click)="onAddGroupClick(dataItem)"

></button>

<button

kendoButton

icon="k-icon k-i-filter-add-group"

(click)="onAddClick(dataItem)"

></button>

</kendo-buttongroup>

<kendo-buttongroup>

<button

kendoButton

icon="k-icon k-i-close"

(click)="onDeleteClick(dataItem)"

></button>

</kendo-buttongroup>

</ng-container>

<ng-container *ngIf="!dataItem.isHeader">

<div>

<button

kendoButton

icon="k-icon k-i-close"

(click)="onDeleteClick(dataItem)"

></button>

</div>

</ng-container>

</ng-template>

</kendo-treeview>

`

})

export class AppComponent {

public instructionJson: any = {

triggerType: null,

url: null,

items: [

{

isHeader: true,

operator: "And",

items: [

{

isHeader: true,

operator: "Or",

items: []

},

{

isHeader: false,

items: []

},

{

isHeader: false,

items: []

}

]

}

]

};

public isExpanded = (dataItem: any, index: string) => {

return true;

};

public onOperatorSelectionChange(event, operator: string, dataItem: any) {

dataItem.operator = operator;

}

public onDeleteClick(dataItem: any) {

let parentDataItem = this.getParentDataItem(this.instructionJson, dataItem);

if (parentDataItem) {

if (dataItem.isHeader == true) parentDataItem.items = [];

else this.remove(parentDataItem, dataItem);

}

private getParentDataItem(currentParentDataItem, dataItemToFind) {

if (

currentParentDataItem &&

currentParentDataItem.items &&

currentParentDataItem.items.length > 0

) {

for (let childItem of currentParentDataItem.items) {

if (childItem == dataItemToFind) {

return currentParentDataItem;

} else {

let parentDataItem = this.getParentDataItem(

childItem,

dataItemToFind

);

if (parentDataItem != null) return parentDataItem;

}

return null;

}

private remove(parentDataItem, dataItemToDelete) {

const index = parentDataItem.items.indexOf(dataItemToDelete);

if (index > -1) {

parentDataItem.items.splice(index, 1);

}

public onAddGroupClick(dataItem: any) {

dataItem.items.push({

isHeader: true,

operator: "And",

items: []

});

}

public onAddClick(dataItem: any) {

dataItem.items.push({

isHeader: false,

items: []

Is there a way for percentage column widths?

I would like to distribute the columns on a percentage basis on the grid. Is there any way to do that?

I managed to do that using CSS. However, this no longer works as soon as "grouping" is used. A "colgroup" element is inserted, whose "col" elements also need a width. Is it possible to give these "col" elements a style somehow?

I have created a small example of this. It looks good at first sight. As soon as I arrange the columns differently or use a second grouping level, the distribution is no longer correct.

Retain previous value on error check

Hello,

I'm trying to retain the value of the combobox on action error. After the user selects an option from the combobox, I run a database query to check if the option selected is valid, if not, I want the previous option to stay selected. Example: Combobox value = "N/A", user selects "COMPLETED", db check fails, combobox value should be 'N/A". I add the code below, hope to get some help with this.

Thanks,

Carla

<kendo-combobox id="complete-button"

(click)="$event.stopImmediatePropagation()"

[data]="stateListDictionary[task.id]"

[value]="stateListComboDefaultDict[task.id]"

[placeholder]="'Change State...'"

(valueChange)="updateTaskStatePerExperiment($event, task, experiment)"

[disabled]="stateListComboDisabledDict[task.id]">

</kendo-combobox>

if (taskId === 17) { // Pre Review task needs an extra check

this.checklistApiService.getPreReviewTrackValue(this.expId).subscribe(data => {

let dataLength = data.length;

if (dataLength != 0) { //there is a track value set, so it's ok to change

this.updateTaskHelper(taskId, status, taskItem, experimentItem);

} else { //there is no track value

if (status != 'COMPLETED') { //setting status other than Completed is ok

this.updateTaskHelper(taskId, status, taskItem, experimentItem);

} else { //status is 'Completed' so throw error

this.stateListComboDefaultDict[taskItem.id] = "TEST";

// this.populateCategoryChildren(this.gateId); // @TODO find a better way to clear 'COMPLETED' and keep the previous value that should not change

let toast:Toast = {

type: 'error',

title: 'Task status could not be updated',

body: 'The task could not be updated. Please select a Review Track in the Pre Review tab',

showCloseButton: true

};

this.toasterService.pop(toast);

}

}, err =>{

console.log("Request Service Error => [getPreReviewTrackValue in gate-checklist page] generated while getting review track  " + err);

return false;

});

} else {

this.updateTaskHelper(taskId, status, taskItem, experimentItem);

}

Grid with virtual columns and reorderable

Hi,

I have problem with grids and treelists where is virtualColumns set to true and with enabled column reordering. After reorder data in rows stays in old columns, only headers are in new places. Is there any workaround for this issue? Reloading data does not fix this problem.

Export multiple grids to the same page

Hi,

Telerik Grid documentation has section "Exporting Multiple Grids to the Same PDF", but following the proposed solution each grid is exported to its own page.

If I try to set multipage option for the root group, all grids are exported to the first page, but all the data is exported at the same place, so I can see only the last grid.

Is there a way not to break pages while exporting grids? Or maybe a way to transform drawing group so I can move each grid lower?

Regards,

Sergey.
