Asp.net Grid View Check boxes to Text box - javascript

I got a minor problem. I am displaying data from a database table in a .aspx page in the form of a grid view.
The first column is check boxes for each individual row and a header check box to implement the check all and uncheck all functionality which I already did using javascriptC. The purpose is general purpose...i.e. each check box represents the row which it is present in.
The problem is as I check the check boxes- either some or all or none....the sum of the values in the selected rows should be displayed dynamically in a text box in the same page below.
Please tell me how to implement this functionality. Just a basic hint or syntax is sufficient. I will do the details myself.
Please tell me the functionality for a simple grid view with two columns- one check box and the other being some values. so I want to display the sum of selected values into a text box in the same page below. This is the problem in simple words.
Thanks in advance for the help.

Concept
Calculate method
create first a method that will iterate over all the items in the grid view, and it will verify if the column is checked, if the column is checked then you add the value to the result variable. At the end of the iteration you update the value of the textbox/label or whatever will display the calculated value
Event
then you will have to use the onCheckChange of the checkboxes or on click to call the "calculate method"
Code
to loop in the grid: Looping through GridView rows and Checking Checkbox Control

How to get selected values of all dynamically created multiple dropdowns using jquery

I have created dynamically row with drop-down list, i want to get all selected values from dropdowns of rows with JQuery. Please help me.
Since you haven't posed any code snippet, I'm just gonna wing it, assuming it's a standard <select>-box.
// Loop all parents and grab the value which is set by the browser whenever update occurs.
var values = [...document.querySelectorAll('select')].map(x =>x.value)

How to get button to act as column search filter within ag-grid and search for a set list of items?

SUMMARY: I have a column for ids within an ag-grid table. How can I get a button-click to only display some of the rows (for which I have a list of ids), while not re-writing the whole table?
BACKGROUND: I am using the community version of ag-grid and am using it with Javascript. I have a column with the id numbers in it. When I click a button (or something else eventually, but start with a button for simplicity), is it possible for it to act as a filter within the table, and hence could be undone by clicking another button to clear the filter?
In case that wasn't cleaar, I am looking to do:
1. Click button1
2. Display certain rows within a table whose id numbers are in my list variable
3. Have this button1's action act as a filter that can be undone by a button2 (which could be programmed perhaps like a clear filter button)
Is this possible to do with a quickfilter? Otherwise, if this isn't possible, how could I do this when over-writing the table, whilst still having the option to 'instantly' revert back to the original table
(I don't think I need to add code as I am unsure of how to build in this functionality)
Thanks in advance.

Getting row data on Interactive Report

Morning,
I'm currently using an Interactive Report on APEX that contains several columns, some of them being checkboxes that represent if a certain number is present in the table that is being used to fill the report.
For example, row 1 has a telephone number "99091021", row 2 a provider, and the following 5 rows are checkboxes that should represent branches in certain areas. If a checkbox is clicked, it means that this number is present in that area.
Now, I'd like to create a dynamic action that inserts that number into that table when I click the checkbox (and it becomes checked), and a delete for when it's also clicked (and becomes unchecked). Problem is, I don't know how to access the rest of the data in the row of the IR to use as a comparison for the delete and insert statements.
Say I try to click the Checkbox 3 on the row where the telephone number is "99091021". A dynamic function would get the data row, then a true action would compare the necessary data to perform either an insert or delete, depending on the state of the checkbox. That's the plan.
I've done something similar before, using localStorage, but it didn't quite work, because before I used it on an interactive grid. Is there a similar function for interactive reports?
Also, is there a way to check if a checkbox is checked or unchecked in a PL/SQL Code?
Here's the solution I found:
I had a select that got the necessary data for the Interactive Report, but because I kept getting an error of temporary data table being exceeded and always breaking the server, I had to change the checkbox query to something like this:
apex_item.checkbox (1, '1_'||a.pk, case when max(decode(b.nr,1,1,null)) is null then '' else 'CHECKED' end) as checkbox1
The '1_' part represents me selecting the first checkbox. With the value still there as the selection, I was able to do the following:
$s("P165_GET_PK",this.triggeringElement.value)
The result would basically be "1_PK_number". With this function I was able to get the value (a.pk) hidden in the checkbox to an Apex item, and then continue using it for my insert and delete statements. It's just a matter of separating the value in it with substring functions and so on.
Now I can delete or insert new data inside that table with a simple click.
I hope it helps in case someone tries doing something similar.

Angular ng- grid - hide/remove column input from column menu

When you use the flag 'showColumnMenu' with true value.
the ng-grid is rendered with button on the right end top panel.
Using this button we can hide/show the column on the grid.
In my Case I don't want to make it possible for some column to be visible on the grid - Meaning I want the the column menu box will be rendered with out some column.
Iv'e created plunker which demonstrated my problem
> http://plnkr.co/edit/VXOzBIRfyY3FoCTct9PI?p=preview
In that plnkr - I set column 'Id' to be invisible using (visible: false)
But if the user click on the column menu on the right end panel
he will be able to set it visible..
EDIT
Another scenario that I need to cover is case where there is some other
column say 'name' that I don't want the let the user configure it (by setting it as invisible) inside the column menu - meaning that column 'name' must always be on the grid!
and the user does not need to see it in the column menu..
So, if only i could hide those columns (id,name) inside the column menu
my problem will be solved..
Thanks!
You can do that editing a bit menuTemplate.html in ng-grid source file
Find line starting from :$templateCache.put('menuTemplate.html',
and line
<label><input ng-disabled=\"col.pinned\" type=\"checkbox\" class=\"ngColListCheckbox\" ng-model=\"col.visible\"/>{{col.displayName}}</label>\r" +
change to
<label ng-hide=\"col.colDef.alwaysVisible\"><input ng-disabled=\"col.pinned\" type=\"checkbox\" class=\"ngColListCheckbox\" ng-model=\"col.visible\"/>{{col.displayName}}</label>\r" +
now you can add
alwaysVisible:true
to columnDefs and it's done
Please see here working demo http://plnkr.co/edit/qmoILJ5LTMSlH7Uv9Rw8?p=preview
Why not just turn off the column menu? It sounds like you basically don't want to use it anyway. Is it important for your users to be able to hide the age column, when they can't control any other?
For hiding ID, I'd recommend not putting in the list of columns in the first place. Even if you don't include it in the grid, it will still be present in the data and accessible by your code. The grid is just a place to display information to the user, so don't put info in there that you don't want to display.
Edit: Check out UI-Grid, the updated version of the Ng-Grid project: http://ui-grid.info/
It has a new ColumnDef property, "EnableHiding" for exactly this case.
Here's their documentation for upgrading from ng-grid: http://ui-grid.info/docs/#/tutorial/099_upgrading_from_2

Is there any CallBack function which is called before/after data is loaded in Angular Js ng-Grid?

Presently i have a Angular Js Grid which is pagination Enabled say 5 records per page for example and total number of records is 2000, so there are going to be 400 pages in All.
when pagination in ng-grid is handled the gridOption data is specified per page which means for 1st page the gridOption will be 1-5 rows for 2nd 6-10 rows and so on........
Here i have implemented a selection functionality through checkboxes thus whenever a row is selected[checkBox becomes selected] and it's stored in selectedItems array and i show selected items in another grid like this.....
Now when i move on to second page[pagination] and select further rows like this ...
The real trouble lies here when i again go back to the previous page i.e page 1 the checkboxes will not be checked because in pagination we load data runtime thus the pages shows following result...
Hope you must have understood my problem....
what i need here is a callback before/after data is loaded so that i can select the checkboxes as i have the number of selection preserved
OR any other workaround for my problem will be much helpful too.
Thanks!.
Can you store the checked value on the data model where you are storing the row values? Then you come back and its just checked by Angular bindings?
I am not sure of your setup, but I do this in a similar situation.
I have been working on this for a couple days now.
While I am still unable to preserve selection across pagination, I am able to clear selections while simultaneously "deselecting" the select all checkbox.
The allSelected variable is not exposed in the gridScope but you are able to grab it and address it using the following code.
// Use this to deselect all options.
$scope.gridOptions.$gridScope.toggleSelectAll(null, false);
// use this to find the allSelected variable which is tied to the
// (the ng-model related to the select all checkbox in the header row)
var header = angular.element(".ngSelectionHeader").scope();
// use this to turn off the checkbox.
header.allSelected = false;
I'll follow up again if I manage to get the "reselecting" to work as documented, but for now I might remain content with this.
