I am using 'CheckColumn' in 'gridpanel' and also I am using a window which contain a chart. In the window, when I click on some values in the chart, I have to set the corresponding check box as checked in the grid. My question is how to set a check box as checked programmatically? I got the row id of the corresponding value that I need but I do not know how to use it to check it.
Thanks a lot!
// in the code below, i am searching for the specific row how contain my value
grids.getStore().each(function(rec){
var rowData = rec.data;
if (rowData['value']==value)
{
var record = grids.getStore().getAt(rec.index);
// what i can do now? // thanks
}
});
i found what i need , just: add
rec.set('myfield', true);
thanks

I am using JsGrid in my asp.net application. I felt it was very awesome grid. Everything worked out very well, but I was stuck at one point.
I have a dropdown on a page which is fetching data from database. and next to that control, i have added JsGrid.
When I change the index of dropdown, and when I click on Add row on my jsgrid, it should set the default value for one of the fields in the grid.
Can anybody please help me out in this regard.

Redefine insertTemplate of the grid column you want to set default value to and pick up value from your dropdown widget:
insertTemplate: function() {
var input = this.__proto__.insertTemplate.call(this); // original input
// getValueFromDropDown() should read value from your dropdown control
var defaultValue = getValueFromDropDown();
input.val(defaultValue)
return input;
}

I want to fetch the selected option from dropdown. I know I can get selected option with jQuery(dropdown).val(). But I am not able fetch the selected with the 'val' function.
Am I doing anything wrong here?
Just use this:
var selectedValue = $('.daterange-preset').val();
(Note: I was able to see your code and get your class name by zooming in, but in the future please post the code rather than a screenshot.)
try using .on( "change" and then finding the option where selected has been applied. I have attached a jsfiddle with a working example that will alert you the value of the selected option everytime you change it.
$('.datarange-preset').on( "change", function(){
var datarangeSelected = $('.datarange-preset').find(":selected").val();
alert(datarangeSelected);
});

I figured out the issue. In my code at one place dropdown value was getting set with the null.
$daterangePreset.val(someVarialwithNullValue);
Because the value was getting set with null. I don't see any update in the HTML. HTML still shows one of the option as 'selected'. So when I was trying to get the selected value with following syntax it was always returning null.
$daterangePreset.val();
You can use a variant of:
var text = $("option:selected").text();
var value = $("option:selected").val();
I have a users grid. To delete one, select your row and click a button "delete".
But, this not work.
My code is:
var row = userGrid.getSelectionModel().getSelection();
console.log(row.get('dni'))
Firefox says:
TypeError: row.get is not a function
Any idea ?.
It is good practice to always check hasSelection() like -
if (userGrid.getSelectionModel().hasSelection()) {
var row = userGrid.getSelectionModel().getSelection()[0];
console.log(row.get('dni'))
}
perhaps because
getSelection( ) : Ext.data.Model[]
Returns an array of the currently selected records.

I am using Yahoo UI library, in particular this example.
What I want is to get a particular column's value when clicking (selecting) a row.
I am using this code:
var makis = function() {alert("blabla"); };
myDataTable.subscribe("rowClickEvent", makis);
and works, but I just don't know how to get a column's value in the particular row.
Ok i found it on my own, i am posting if anyone has the same problem.
myDataTable.subscribe("rowClickEvent", function(oArgs) {
var elTarget = oArgs.target;
var oRec = this.getRecord(elTarget);
console.log("value:" + oRec.getData("column_we_want"));
}
im having a set of multiple check bxes, like one set contain 3 check box share same name another set contain 3 check sharing same name . how can i get the value of these two different set of check box using a single code .
var form = $('usersurvey');
checkboxes = form.getInputs('checkbox');
for(count=0; count< checkboxes.length; count++){
if(checkboxes[count].checked){
retValue=true;
break;
}
}
return retValue;
}
im tried with this code but it fetch all the check boxes , i want only that have the same name, i used prototype.js
if you give each set of checkboxes a different class you could select them using jquery like:
$(".className").each(function(index, element) { ... });
for instance. somebody may be able to improve on this solution by selecting by name (i wasnt sure if you could do that, i always just select by class).
EDIT: sorry i should elaborate probably. the $(".className") piece will select all the checkboxes of class 'className'. since it sounds like you want to DO something with each of them though, i just added the each call on the end. inside the each call, you can define a function (shown) that will do something for each checkbox that was selected. reference the jquery each docs here:
