Customize Dynamic Data Table

Dynamic Datatable should be used where the datasource is dynamic i.e., number of columns, its types and column names etc. change depending on a specific condition.

Making Dynamic Datatable as Editable table​

For making dynamic datatable to work as editable datatable, then add below code in the markup.

<wm-table-action widget-type="button" key="addNewRow" display-name="New" iconclass="wi wi-plus" show="true" class="btn-primary" action="addNewRow()" shortcutkey=""></wm-table-action>
<wm-table-row-action key="updaterow" display-name="" title="Edit" iconclass="wi wi-pencil" show="true" class="btn-transparent" action="editRow($event)"></wm-table-row-action>
<wm-table-row-action key="deleterow" display-name="" title="Delete" iconclass="wi wi-trash" show="true" class="btn-transparent" action="deleteRow($event)"></wm-table-row-action>

Add these add New, edit, delete actions in markup of the <wm-table >{CodeHere}</wm-table> tags.

Customize Column Names​

If the column names has any special chars, then the special characters will be removed for the column name by default. If one wants to display the column name as it is, then write the below code in onBeforedatarender event.

Example: If the column name is 0-100 then for the datatable the column name in the header will look like 0100 by default. To override this behaviour use below code.

Page.dynamicdataTable1Beforedatarender = function(widget, data, columns) {
    //The below code will iterate all the columns and sets the column caption same as key
    for (const key in columns) {
        columns[key].caption = key;
    }
};

Styling Cell in the datatable​

To apply conditional style for the cell based on the row data then write the below code in onBeforedatarender event.

Page.dynamicdataTable1Beforedatarender = function(widget, data, columns) {
    //Applying conditional class for the column with column Name: '500-600'
    if (widget.columns['500-600']) {
        widget.columns['500-600']['col-ng-class'] = "{'mystyle':row['500-600']=='Rejected'}";
    }
};

In the given example, if the cell value is Rejected then we are applying below styles.

.rowstyle{
    background-color: red
}

Example:

Apply Conditional Styles for row​

To apply conditional styles for the row data then write the below code in onBeforedatarender event.

Page.dynamicdataTable1Beforedatarender = function(widget, data, columns) {
    //Applying conditional class for complete row
    widget.rowngclass = "{'warning':row.CITY=='New York', 'danger':row.CITY=='Atlanta'}";
};

Customize Edit Mode widgets​

As the metadata will be dynamic for the dynamic datatable, the edit mode widgets will be text boxes by default. If we want to customise the widgets as date or number widgets etc., based on the data the below code should be added in onBeforedatarender event.

Page.dynamicdataTable1Beforedatarender = function(widget, data, columns) {
    //Changing the widget in edit mode for column '0-100'
    if (widget.columns['0-100']) {
        widget.columns['0-100']['edit-widget-type'] = "date";
    }
    //Changing the widget in edit mode for column Street
    if (widget.columns.STREET) {
        widget.columns.STREET['edit-widget-type'] = "textarea";
    }
};

Apply View Mode Customizations​

To apply customizations on the view mode data in the dynamic datatable, add below code in onBeforedatarender event.

Example:

For Numeric data 98988.909 to be displayed as 98,988.91(apply 2 decimal fractions and also display data as number).

For data 1973-10-21 to be displayed as 1973, Oct 21.

Page.dynamicdataTable1Beforedatarender = function(widget, data, columns) {
    //Applying display formats for columns in view mode
    if (widget.columns.BUDGET) {
        widget.columns.BUDGET].formatpattern = "numberToString";
        widget.columns.BUDGET.fractionsize = 2;
    }

    if (widget.columns.BIRTHDATE) {
        widget.columns.BIRTHDATE.formatpattern = "toDate";
        widget.columns.BIRTHDATE.datepattern = "yyyy, MMM dd";
    }
};
