You can customize the ListView items using the
template
property. Here,
the dynamic tags are added and removed in the list item from another ListView. Refer to the following steps to achieve this.
actionComplete
event.
Refer to the following code sample of actionComplete event.// The actionComplete event for first ListView to add the button
addButton(args) {
let buttonObj = { obj: ButtonComponent, prop: { iconCss: 'e-icons e-add-icon', cssClass: 'e-small e-round' } };
let ele = document.getElementsByClassName("e-but");
for (let i: number = 0; i < ele.length; i++) {
buttonObj.obj = new ButtonComponent(buttonObj.prop);
buttonObj.obj.appendTo(ele[i]);
}
}
// The actionComplete event for first ListView to add the button
addButton(args);
{
let buttonObj = { obj: ButtonComponent, prop: { iconCss: 'e-icons e-add-icon', cssClass: 'e-small e-round' } };
let ele = document.getElementsByClassName("e-but");
for (let i = 0; i < ele.length; i++) {
buttonObj.obj = new ButtonComponent(buttonObj.prop);
buttonObj.obj.appendTo(ele[i]);
}
}
select
event
(triggers when the list item is selected), in which you can get and add the selected item value as tags into parent
ListView. Refer to the following code sample.//Select the event that is is rendered inside dialog for ListView
addTag(e) {
let listTag = document.createElement('span');
listTag.className = 'advanced-option';
let labelElem = document.createElement('span');
labelElem.className = 'label';
let deleteElem = document.createElement('span');
deleteElem.className = 'delete';
deleteElem.onclick = this.removeTag;
labelElem.innerHTML = e.target.textContent;
listTag.appendChild(labelElem);
listTag.appendChild(deleteElem);
let tag = document.createElement('span');
tag.className = 'advanced-option-list';
tag.appendChild(listTag);
this.listviewInstance.element.querySelector('.e-active').appendChild(tag);
}
//Select the event that is is rendered inside dialog for ListView
addTag(e);
{
let listTag = document.createElement('span');
listTag.className = 'advanced-option';
let labelElem = document.createElement('span');
labelElem.className = 'label';
let deleteElem = document.createElement('span');
deleteElem.className = 'delete';
deleteElem.onclick = this.removeTag;

listTag.appendChild(labelElem);
listTag.appendChild(deleteElem);
let tag = document.createElement('span');
tag.className = 'advanced-option-list';
tag.appendChild(listTag);
this.listviewInstance.element.querySelector('.e-active').appendChild(tag);
