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)

Asp.net Grid View Check boxes to Text box

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

Cloned autocomplete input not working

I have a problem with jQuery function clone(). I think the problem is in the withDataAndEvents input parameter of this method.
Initially, I'm coding a table that has dynamic rows. I'm adding dynamically rows when clicking on a button put only in the first row. the first row contains initially many inputs fields and combo-boxes. Each field is initalized by an ajax call. And each action on a field leads to the refresh (filtering) on the whole fields of a row. I'm also using autocomplete on input fields.
The first row works perfectly. However, when cloning the tag:
If I did not enter values in the first row, the cloned and first row work fine
If I enter a value or values in first row fields and after I clone the , only the first row fields still work. In this case, if I try to change the value of the combo-boxe (which fire a change event for all concerned row fields), the fields of the first row are impacted despite using Ids when changing autocomplete data. Ids of fields, combo-boxes, table rows are dynamically created when clicking on the button to clone the widget.
The code I wrote is too long so I created a fiddle and simplified the case and still have the same problem.
I tried many suggestions that I've found like this, this one or this one in vain :-(
(data.('autocomplete', null), autocomplete("destroy") ...)
Do you have ideas about this issue ?
thanks in advance

Aside from the typo in the test (you are selecting by class instead of the new element by id), the basic problem is you are applying autocomplete before you add it to the DOM.
JSFiddle: http://jsfiddle.net/TrueBlueAussie/87jcw1y0/2/
I just reversed the order of these two lines:
$('.body').append(clone);
applyAutoComplete2('#myinput' + inc);
The cause... Some plugins use storage data associated with the DOM element, or attach events to ancestors etc. None of these can happen with a disconnected DOM element, so just attach it to the DOM first.

I think ur asking this
Check in this link http://jsfiddle.net/bsarunmca/87jcw1y0/3/
applyAutoComplete1('#myinput1');
$("button").click(function() {
inc = inc+1;
$('#myinput1').clone().attr('id','myinput'+inc).appendTo('.add-this');
$('#myinput'+inc).val('');
applyAutoComplete2('#myinput'+inc);
});

Programmatically bring focus on first row in ng-grid

In my project, I have a requirement to bring focus on first row of ng-grid as soon as the grid loads and it should move to next row when I press the down key. I added the following event:
$scope.$on('ngGridEventData', function (e,s) {
$scope.gridOptions.selectRow(0, true);
});
But this event just selects the first row, it doesn't take the focus on first row. The row needs to be clicked to get the focus there. What is that additional statement we need to write to get the focus there?

I reported it on github repo of ng-grid and got the solution. You can check the conversation here: https://github.com/angular-ui/ng-grid/issues/539
We need to add the following statement to bring focus to the selected element:
$(".ngViewport").focus();

I was able to focus on a specific cell doing this:
$($($(".ngCellText.col1.colt1")[0]).parent()).parent().focus();
.col1.colt1 refers to the 2nd column (.col0.colt0 -> 1st column)
In this case I'm selecting the 1st row, the 2nd row will be selected using:
$($($(".ngCellText.col1.colt1")[1]).parent()).parent().focus();
It's a bit hacky, but it works.

A slight variation on the JQuery answer:
$('div[ng-row]').eq(2).find('.ageCell').focus()
This finds the row you want first, the third in this case, and then the column using the column name, 'age' in this case. It's just a bit more resilient if the columns change or are re-ordered.

add div from drop down menu selection jquery

I am able to add a row with the dom but how can I get a div to display to the right of drop down depending on what is selected?
Here is an example of what I have so far: http://jsbin.com/#/afojid/1/edit
The first drop down is working correctly but the rest I would like to add when the button is clicked and I would like them to work the same way as the orginal drop down menu. So that if Asian is selected an add section will appear to the right, if Other is selected an other add section will appear to the right, and so on for each time the add button is clicked. I tried clone but I don't want anything to be selected when the add button is clicked

The fact that you're working with ids instead of classes more or less universally makes this very challenging. You should update your code to work with classes and appropriately clone the *Info tables when you create new dropdowns.
You're using an old version of jQuery, so .on is not available to you for delegation. Instead, use .delegate:
$(document).delegate('#typeofEthnicity,[id^=newDDMenu]', 'change', showEthnicity)
This will call the showEthnicity function for the original dropdown and any added dropdowns, but you also have to clone all of the *Info divs and put them in the appropriate spot in the table (I suppose the same spot as the appended row). If you use classes, then it's a simple matter of finding the dropdown's parent row and then locating the corresponding child with the appropriate class to be shown.
