I have a DataGrid. I'm using combobox in Grid as ItemRender. I want to set dataprovider for item in each row which using combobox. Each row at item which using combobox have different dataprovider. I'm using Flex 3.
The ComboBox dataProviders for each row must be embedded in the dataProvider for the whole Grid, and you can retrieve them selectively in the itemRenderer.

I've got an application that allows a user to select a row in a Kendo Angular 2 grid and click a button that removes that row. After the row is removed, however, the grid selection persists on the index of the row that was just removed. I'd like to clear the grid's selection after the button is clicked and the row is removed. For the life of me, I cannot find a way to do this. Any ideas?
The Kendo Grid control has a property of "selectedKeys" which binds to an array of numbers. You can then clear this array when you want to clear the selection of the grid.
<kendo-grid
[selectedKeys]="mySelection"></kendo-grid>
In your code:
this.mySelection = [];
I am loading some data from a database table in a datagrid in Flex and I require a custome component on the first empty row or on empty rows, so user can add data in to that row. How can I do that? I do not want to make the datagrid column editable.
I'm trying to make a single row of a data grid editable. so if I have 5 rows of complete data these will remain uneditable. however I will have added an additional empty row and this is the only row I want the user to have access to edit. this is being done using as3 in and advanced data grid.
using the editable property of the data grid I have made the entire grid editable but this will be an unacceptable outcome
Specify editable property of datagrid as true but specify all the colums of datagrid editable property false
On ItemClick event check the rowindex.
If rowindex == 5(where u want ur datagrid to be edited) use editable property of datagrid for all colums to true else false
Hope you got it!!!

what i am trying to achieve is to have data populate a datagrid from a query, this part works fine. but once the data has been populated i want to add an additional row which the user will be able to type into. so for example the grid will have 5 pre populated rows and then the 6th row will be empty cells which the user can edit. the final column of this row will either be a button or an image with the click property set. this will be used to run an update query to update the dataprovider of the datagrid.
This is pretty easy. Just add a new object in your List that is bound to the datagrid. For the final column you will need an item renderer.
Ex:
dataGrid.dataProvider = someList;
//later when it is populated
someList.addItem(new Item());
After this you can set the focus to the desired column and the last row to show its input time.
You can also remove the last added item from the list to simulate a cancel action.
You will also need to set the 'editable' property of the grid to true. Set the selectionMode property to 'singleRow' Each column also has an individual 'editable' property so you can limit users to only changing certain properties.
As long as the data is simple text the default item editor (which is a textInput) will work fine. If you use an advancedDataGrid you can also include things like checkBoxes for Boolean data.
I have a Array Collection which contains around 10 items and i have assigned this arraycollection to list component as dataprovider. Is there anyway that i can display only the first 5 items in the list component without removing remaining 5 items from array collection.
You can wrap the ArrayCollection in another ArrayCollection and then apply a filter function to the first one. That way, your original collection will not be affected by the filter.
