Question

16:20 Sep 18, 2024

I have a list page, and its data source is a spesefic object we have created. above the list table there is a search element. What i want is when there is no filter applied the list table should be empty and, when any filter is applied then it should show only the matching resluts. How can i achieve this? What now happening is it is showing all of the existing records, but when i wanted to set up a business rule I could not find any option to access search element.

Zulaykho,

Clear the list isn't an easy task and needs a development team to be involved. Instead, you can prevent the list load by showing the Error message to the customer:

{
	request: "crt.SearchFilterColumnsGroupsRequest",
	handler: async (request, next) =&gt; {
		const searchValueLenIsZero = request?.value?.length == 0;
		const isEmptySearchValue = request?.value?.trim().length == 0;
		if (searchValueLenIsZero || isEmptySearchValue) {
			Terrasoft.showErrorMessage("There is no filter");
               } else {
                 await next?.handle(request);
               }
	}
}

Best regards,

Anhelina!

Question

How to run a process from list.

Jose Hernandez

19:35 Mar 28, 2023

Hello,

I'm trying to learn the new Studio 8.0.6 front end development way of doing things as it is very different from the 7 versions. I started by creating a list and I want an action menu that calls a process that will update some fields on the record and then opens it.

I found this article Set up a custom action menu for list and list records | Creatio Academy that explains how to add custom actions from a list, but I cannot find a reference that shows how to do the same but instead of opening the page, to run a process and the opening a page. Is there a reference to all the existing handlers?

I found some of them on the SysUerProfilePage but not one to run a process.

Thanks,

Jose

Cherednichenko Nikita,

Thanks for the link but the information there works for the 7.x versions but not for the Freedom UI pages on the 8.0.6 version.

I figured it out how to accomplish that on a Freedom UI page by looking at the code generated by Studio when adding a button in the page that calls a process, this article Set up a custom action menu for list and list records | Creatio Academy and by the information on this link Receiving Server-Side Messages in Client-Side Code on a Creatio Freedom UI Page | Customer FX

The code looks something like this:

viewConfigDiff: /**SCHEMA_VIEW_CONFIG_DIFF*/[

   ...

   {

       "operation": "merge",

       "name": "DataTable",

       "values": {
