Grid had been added element by Row and Column,i want to add new element to grid by follow way:
grid.children[i] =element as UieElement;
It is invaild to me.have a error.
I am avoiding refresh in thread,so i have not clear Grid.Children.
try this :
grid.Children.RemoveAt(i);
grid.Children.Insert(i, element as UieElement);
(also, but I think it as a typo : Children should be capital C in grid.Children ...)
To add elements, this is how you would have to do it:
grid.Children.Add(element);
If you want to set the row/column, you can set the properties programmatically before adding it, like so:
element.SetValue(Grid.RowProperty, 1);
You can access an existing portion by index like in your example if you just need to access a specific child.

I am trying to write a locator where the next text descendant is returned. I wont know the text. The following xpath works:
//*[#id='myChart']//label[contains(text(),"Show:")]/following::div[4]
but I dont like the div[4] as this could easily change. The element is the first div type descendant under show that contains text. Any suggestions?

Considering the following clauses:
the next text descendant
I wont know the text
div[4] as this could easily change
element is the first div type descendant
To locate the element a couple of effective approaches are as follows:
Using xpath:
//*[#id='myChart']//label[contains(., "Show")]//div[text()]
Using xpath with descendant:
//*[#id='myChart']//label[contains(., "Show")]//descendant::div[text()]
Using xpath with following:
//*[#id='myChart']//label[contains(., "Show")]//following::div[text()]
I think this will work for you:
//*[#id='myChart']//label[contains(text(),"Show:")]//div[text()]
To give more confident answer we need to see the actual page / XML.
In case the desired div is a direct child of the label containing the "Show:" the above expression can be presided to
//*[#id='myChart']//label[contains(text(),"Show:")]/div[text()]
I have two forms which are extended from another form. I want to add some fields to one of them but not at the bottom of the form. I use add method and my items are added at the bottom of the form.
Does anyone have an idea?
You need to use insert method on container instead of container.add to update the layout.
The insert takes two args,
first : index to insert at
second: the element to be inserted (could by a couple of other things)
In your case the form serves as the container so you need to do something like (assuming you are on Ext 5.x or lower):
var newField = Ext.create('Ext.form.field.Field', {});
var insertAt = 3;
yourForm.insert(insertAt, newField);

I have a ItemSelector component inside a Window. I have implemented a search functionality that dynamically finds the matching entry based on user's keyboard input.
Now I just want to highlight/focus such item inside the ItemSelector.
I'm looking for something like:
// when the search returned a result and got the related index in the store
function onSearchPerformed(index) {
var cmp = this;
cmp.itemSelector.setSelected(index); // here I'd be highlighting the entry
}
Example
Imagine a simple ItemSelector like this one taken from the web.
User types 'Delaw' and my search function detects that there is an entry with name Delaware and it's at position 3 in the store.
All I want to do is to programmatically highlight the row/entry 'Delaware' just as if you clicked on it.
This ux component uses a boundList, or better 2 of them.
A from and a toList.
You need to get a reference to the right boundlist.
More on that you will find here: http://docs.sencha.com/extjs/6.0.1/classic/src/ItemSelector.js.html
Basically you can do something like this:
https://fiddle.sencha.com/#view/editor&fiddle/24ec
afterrender: function(cmp){
Ext.defer(function(){
var boundlist = cmp.down('boundlist');
item = boundlist.all.item(1);
boundlist.highlightItem(item);
},300);
}
After you have a ref to the correct boundlist, you can simply highlight the item using:
http://docs.sencha.com/extjs/6.0.1/classic/Ext.view.BoundList.html#method-highlightItem
Take care that you may need to call following function before:
http://docs.sencha.com/extjs/6.0.1/classic/Ext.view.BoundList.html#method-clearHighlight
To find the correct item should't be too hard.
There are two ways to solve the issue
One is by following #devbnz answer, marked as correct. This is preferable, if you just want to graphically highlight the entry without triggering any event.
However, by hovering on other entries, you will lose the highlight on your current entry.
The second one, as suggested by #guilherme-lopes in the comments, may be preferable in cases in which you want the selection to act as if you actually clicked on an entry, which will trigger the selectionchange event and similar...
Depending on the situation, I ended up using either.
For instance, is it possible to define:
#FindBy(By.id("id1") OR By.id("form1:id1"))
public WebElement button
So that button having either "id1" or "form1:id1" should work fine?
You can use the #FindBys annotation, the syntax is:
#FindBys({#FindBy(id = "foo"),
#FindBy(className = "bar")})
The JavaDoc describes it here:
http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/support/FindBys.html
Well,
use whathever you want, as long as it works
Personally I would use #FindBy(By.id("id1")) but it is just point of choice.
Also, there is no value added in referring same element twice with two different methods. It will only cause mess in your code
EDIT
As I understood your comment, there is element on the page which constantly changes its ID. If you need to refer to such elements, try using xPath See for example this xpath tutorial
The idea is that you will point to some place in the DOM rather than to specific ID
Use Xpath or CSS selector to do that. Or Java to store the ID name in String and then you can fill it to your Id.
I have an Array to be displayed in a CakePHP View which contains the navigation data. Each array item contains fields like id, name, level etc. as well as another array field named children, where this structure repeats.
In the Cake PHP View it's easy to walk over the array on the first level with a foreach loop and the html-Helper to output the relevant data. But how do I ouput the child items (and then their children if present)? Normally I would do a recursive function call, but within the view you shouldn't use function look, should you? Bunt within the controller I cannot use the html helper, so I'm stuck here.
I think as a clean solution to make a helper to iterate over the array an recursively look for each elements if one of them another array (http://book.cakephp.org/#!/view/1097/Creating-Helpers)
Or if you know that your item could has one and only one child, you could ask if the actual item is an array an operate it. But I prefer the first solution.
It looks like you might try the tree behavior
http://book.cakephp.org/#!/view/1341/Basic-Usage
you need something like a recursive method that can call it's self, something like the following. https://github.com/infinitas/infinitas/blob/beta/core/menus/views/helpers/menu.php#L163
