[VUE 2] Slow widget render time
Posted: Fri Mar 10, 2023 10:26 am
Hello!
We tried to use widgets to display 3 cells inside one cell with the following really simple code:
async getDataColumns(columns, region) {
return columns.map((m) => {
var columnType = "number";
return {
type: columnType,
format: this.getFormat(columnType),
// type: "widget",
field: m.dbColumnName,
text: m.displayedName,
region: region,
editor: false,
cls: m.isKey == true ? "current-column-header" : "",
cellCls: m.isKey == true ? "current-column" : "",
isCurrent: m.isKey,
widgets: [
{
name: m.dbColumnName,
format: this.getFormat("number"),
},
{
name: m.dbColumnName,
format: this.getFormat("number"),
},
{
name: m.dbColumnName,
format: this.getFormat("number"),
},
],
};
});
},
The render time increased a lot if we use it in tree view (tried to open a row and was much slower than before) or the same thing happened if we try to change the data in the columns.
Is there any suggestion what can improve the performance? What we did wrong?
Thank you!
