I have a List collection an entity with
salary,desgn,salaryId, salary_basis,
from here I want to fill the textbox at textchanged event, the desgn,salaryId, and salary basis
i queried from db and filled the collection. I have done it with entity but cant do with collection....
Any suggestions....
emdad,
Emdad why not use loop to work on each element of the collection.suppose you collection have more than one element ,on loop just take one by one element then work on it,what ever you want .Hope this solve your problem

I am trying to extract the Table which has the following format
When I want to extract i should have either put some character on place up icon or i dont want that either the case is fine..
But UIPath brings this way.. 78,59,237806 all as one text which is misleading.. How to resolve this issue..
Thanks
Take a look at the Find Children activity. You can specify an item via selector (the table) and use Find Children to return a collection of type UiElement.
So set the filter to extract the "<webctrl tag='tr' />" which will effectively give you a collection of the rows.
Use a For Each to iterate through each UiElement you got from the first Find Children activity, and use that element to run another Find Children. In this case, set the filter to extract the elements with a class of "mid-wrap". This gives you a collection of the elements in the row which match that requirement, and this will exclude the data-up value, since that's a different class.
You can then loop over this collection to get the innertext attribute, which will give you the actual values you're looking for each cell in the row. Use something like Add Data Row to add the values to a datatable, and let the For Each run over the next row in the collection.
I have a grid where the user can select records via checkbox in front of every record. Now I have a requirement to sort the records based on their selection, so that all selected records should be placed top, followed by the not selected ones.
Is there any standard function to achieve this? As an alternative I thought of saving the selection state as an attribute on every record and sort based on the attribute.
The code for the column is:
gridRealmDt.setSelectionType(SelectionStyle.SIMPLE);
gridRealmDt.setSelectionAppearance(SelectionAppearance.CHECKBOX);
I try to describe the code I use as the affected code is deeply nested in our own framework classes.
gridRealmDt is a subclass of smartgwt ListGrid. In my Dialog a create an instance of the grid which creates an instance of a database bound datasource. When the dialog is loaded the records are fetched from the database and after that a registered an dataArrivedHandler where I select the records which match records from another table.
I tried to place the selection attribute in an extra field and use that for sortig before my other sort criteria, but this does not work. Here is the code for the field I am using.
ListGridField txtSelected = new ListGridField(SELECTED, "");
txtSelected.setHidden(true);
txtSelected.setSortByDisplayField(true);
txtSelected.setCanSortClientOnly(true);
When I do not set the canSortClientOnly property the order by is sent to my database resulting in an error, as the table does not contain that field, so I set the property. Now I get following error
Removing field from the sort Specifier array because it specifies canSort Client Only: true and all data is not yet client-side.
I also tried to use a sortNormilizer on the Name field which is my main sort criteria, but the normalizer is called before the selection value is set to the record.
record.setAttribute(CARealmDS.SELECTED,selected ? "a" : "b");
I also cannnot find a way to call the normalizer when selection changes.
Currently we are using Smart GWT Version 6.0p.
I don't think there is any standard function. Just use grid store update. Place checked items first.
Is it possible to have data in a Handsontable sorted by a field which is not displayed? I have a grid of data which I would like to display that contains a column called "sortOrder", but I don't want to display this.
The sorting needs to be done client side because events are coming in over web sockets and need to be reflected in the table.
If you're not showing the column then I assume you're not expecting the user to be able to manually sort by this hidden column. Therefore, why don't you simply sort your data array with native JS? At any point during execution you could have a function which sorts by this hidden column and then just don't render this in your Handson definition.
So yes, the answer is it is possible. The not showing of a column is as simple as defining the columns option and not including a column for this hidden value.
I am new to handsontable.
My handsontable rows are readonly.
I wanted to remove all rows of handsontable on a button click.
Please help me.
Do update with empty dataset:
handsontableInstance.updateSettings({
data : []
});
This removes all rows (and leave header if there is some).
There are many ways to "remove" all rows. For example, one, and the easiest, would be to empty your data array. So say that you initialized your HOT instance with the data field as array dataArray. Your button would only need do:
$("#buttonId").click(function() { dataArray = [];})
That would be the easiest way but of course you'd be bypassing HOT. This means that if your application gets more complex and you rely on handlers such as afterRemoveRow, then this method will bypass them. In this latter case, you'd want to use the hot.alter() method as follows:
hot.alter('remove_row', 0); // would remove the row at index 0;
With this I am assuming you know how to use a for loop that could iterate through all rows and remove them, one by one. An expensive operation but it would ensure all the proper handlers get called.
tableInstance.clear()
Clears the data from the table (the table settings remain intact).

I have an Infragistics Ultragrid that is being used to display a list of attributes. Sometimes the attribute is an array so I am adding a sub row for each element so the user can optionally expand the row showing the array attribute and see all the element values.
So for each element I use:
var addedRow = mGrid.DisplayLayout.Bands[1].AddNew();
which if I have 300 elements gets called 300 times and takes around 9 seconds (I have profiled the application and this call is taking 98% of the elapsed time)
Is there a way to add these sub rows more efficiently?
I know I'm late with an answer, but hopefully someone can use my answer anyway. Whenever I need to set rows and subrows for ultragrid, I simply set the datasource by using linq and anonymous types to generate the propper collection.
say you have a list of persons (id, Name), and a list of cars (id, CarName, and OwnerId (personId))
now you like to show a gridview showing all persons, with an expandabel subrow providing which cars they own. simply do the following.
List<Person> persons = GetAllPersons();
List<Car> cars = GetAllCars();
grid.DataSource = persons.Select(x => new {x.Id, x.Name, Cars = cars.Where(z => z.OwnerId == x.Id).ToList()}).ToList();
Note the anonymous type I make, this will generate a list of objects having an id, Name, and a collection of cars. Also note that I call the ToList method twice in the last line, this is necessary in order to get ultragrid to bind properly.
Note further more that if you need to edit the gridview, the above method migth not be sufficient, as the ultragrid needs an underlaying datasource for modifying, and I dont believe that this will cope. BUT on the internet you'll find some extensions that can copy a Linq collection into a DataTable, doing that and then you should also be able of editing the grid.
I have often used the above method and it performs extremely well, even for huge collections.
Hope this helps somebody
you might want to use ultraGrid1.BeginUpdate(); and ultraGrid1.EndUpdate(true); to stop screen from repainting. made huge performance benefit for my app.
Also in my case I was populating nearly >10,000 rows, so have used UltraDataSource
