How To Capture Clear Button event

Recommended Posts

I am using the version of UniGUI / Delphi XE6 and created a new inherited component TUniDBLookupComboBox. I'm using the property clearbutton true and would like to execute a statement when the user clicks the X button (ClearButton). Is there any event that triggers the component when it is clicked the X (ClearButton)? How can I handle this event?


Best Regards,

This event is handled and used internally on client side. It is not sent to the server, so it can not be handled without additional implementations on client side.

Can you try this approach?!:


For example:


UniDBLookupComboBox1 -> ClientEvents -> ExtEvents -> afterrender fn:

function afterrender(sender, eOpts)
    sender.plugins.forEach(function(p) {
        if (p.alias[0] == "plugin.clearbutton") {

            // default click handler:
            // handleMouseClickOnClearButton: function(event, htmlElement, object) {
            //     if (!this.isLeftButton(event)) {
            //         return;
            //     }
            //     this.textField.setValue('');
            //     this.textField.focus();
            // }

            // remove default click handler if is needed
            p.clearButtonEl.un('click', p.handleMouseClickOnClearButton, p);

            // add your click handler
            p.clearButtonEl.on('click', function(event, htmlElement, object) {
                // your logic

Best regards.
