Set same value for multiple records/refresh GridPanel

    Set same value for multiple records/refresh GridPanel

    Hello,
    I need to accomplish the following:

    I have multiple records in a GridPanel, each record has a property called "Status".

    1. In case the user wants to set the same status to more than one record, they should be able to select as many records as they need.

    2. Once more than one record is selected an "Update Status" button should appear in the top tool bar.

    3. When the user clicks the button a modal form with status drop down should appear, the user would select desired status and click "Save" button. This would update the status of every record that was initially selected in the GridPanel.

    4. Once the data is saved, the modal form would disappear and the data in the GridPanel would reflect the change.

    See attached screenshots.

    I was able to figure out how to do 1, 2, 3. But I can't make the new status appear in the gridpanel records once the window disappears, only once the user reloads the page manually.

    Is there an example of something similar to this I can look at? or should I submit a simple test case?

    Hi Dennis,

    Can you provided a simplified sample demonstrating as much of this scenario as you can. We can try to fill in the pieces that are not working.

    Some tips on creating samples for the forums:

    Hello @Dennis!

    Cycle through the selected records the way you probably already know, and set the record fields' to the new value you want.

    The new values should be reflected to the grid once you then call the grid's .reconfigure() method.

    Hope this helps!

    p.s.: it would help us understand your question if you posted just the part you couldn't figure out, I am still unsure you need or not help with the other points you show in the question. Assuming here you just have trouble updating records with chosen value throughout all selected records.

    Hi Fabricio, here is a standalone simplified example. There are two things I need to get working here:
    1. Show/hide "Update Status" button based on the grid selection (if no records are selected the button stays hidden, once at least one record is selected it should appear)
    2. When the transfer status is updated for selected records StatusEditor -> Edit, and the form disappears. I need the new status to be shown for all the affected records in the grid, without reloading the page.

    Please note - my sample below has client status db update functionality commented out and it includes the editable cells functionality you helped me with.

    Hello @Dennis!

    Thanks for the test case, but I have two points before we get down to it:

    1. it looks pretty extensive for just a grid panel with a column having a mapped "status" value that we can mass-change to another value, don't you agree? Is the save/edit logic pertinent in that case? I feel this could be simplified to a single-page code, without custom controls, etc.

    2. Have you tried the directions in our last post? I don't see in your last post comments or code block about the result of trying the solution... If it really doesn't help, I believe we could try reducing that test case, I honestly am not sure where to start looking at your issue in all that code.

    Hope you understand!

    Fabricio, I am not sure I am following the suggestion you are referring to. Perhaps if I provide the simple requirements you can suggest a simple solution:

    The user needs to be able to select as many records as necessary in the grid (using check boxes), click a button to have a form pop up with a "status" drop down. select the desired status, and click save - this should update all the selected records in db/grid with the chosen status. This is done to allow users mass update records with a status instead of going and updating each record individually.

    I realize that it is easier to have a dropdown and "save" button on the same page as the grid and loop through the selected records of the grid while saving/committing the changes (I already made it work) but that is not what the users' requirement is. As always that would be too easy wouldn't it?

    Thanks !

    Hello @Dennis!

    Cycle through the selected records the way you probably already know, and set the record fields' to the new value you want.

    If you are not sure how to go thru the records, it would be something like:

    App.GridPanel1.getSelection().forEach(function(record) {
        record.set("FieldName", valueFromComboBox);
    });
    The new values should be reflected to the grid once you then call the grid's .reconfigure() method. In other words, following the command above,

    App.GridPanel1.reconfigure();
    If you are mapping the status values from database numbers to human-readable strings, you should update the records with those numbers; when you call reconfigure(), the cell renderer will be evaluated again and the numbers, again, mapped to human-readable values. That is, if in the record field it is stored as a number, you should update it to the corresponding number, and not the "friednly" display string.

    Hope this helps!

    Fabricio, I actually solved part of this issue by calling DirectMethod and bind the data/refresh, it works great. Last issue i am trying to solve is how to make the "Update Status" button appear/disappear based on check box selection in the grid. If there is at least one record selected we would like the button to show up and disappear if no records are selected.

    Thanks !

    Hello again, Dennis!

    Use the CheckboxSelectionModel's SelectionChange listener to check whenever the selection change whether the button should be displayed or hidden.

    Hope this helps!

    Fabricio,
    I found a close enough example of how to use "selectionchanged" listener but unable to get it to work, can you see what I am missing here (onSelectionChange function):

    <%@ Page Language="C#" %>

                this.BindData();
            }
        }
    
        private void BindData()
        {
            this.Store1.DataSource = Client1.GetAll();
            this.Store1.DataBind();
        }
    
        public partial class Client1

                clntList.Add(new Client1() { ID = 11, Name = "Client2"});
