Q1)How to get row from hierarchical grid without using any loops. is their any method like getRowByDataID or something else

If you’re aiming to get the Dom element associated with a specific data key of a row then you can use the “rowById” method:

Q2)How we will change any row content of hierarchical grid and that should be commited to the attached datasource. eg. we have one column called isactive if I change this column to active its changing the grid row value but that value is not updated in datasource. so if I filter it by only active rows its not showing me that changed row.

You can use the “setCellValue” method of the igGridUpdating widget to update a specific cell value in the grid programmatically.

http://help.infragistics.com/jQuery/2014.1/ui.iggridupdating_hg#methods:setCellValue

If the autoCommit property of the grid is set to true (http://help.infragistics.com/jQuery/2014.1/ui.iggrid_hg#options:autoCommit ) then the changes will be reflected on the data source on the client side.

Otherwise you would need to explicitly call the “commit” method: http://help.infragistics.com/jQuery/2014.1/ui.iggrid_hg#methods:commit

After the changes are saved on the client side if you wish to commit them to the server side and invoke the action associated with the UpdateUrl that you have set for the grid, you would need to call the “saveChanges” method:

Q3) Is there any property to assign color to the row in hierarchical grid.

There’s no specific property. If you need to set some style for a specific row you can get the Dom element associated with the row and using jQuery’s css() method apply the properties you want to it.

To get a specific row’s Dom element:

http://help.infragistics.com/jQuery/2014.1/ui.iggrid_hg#methods:rowById

To apply css() to a Dom element:

http://api.jquery.com/css/

Q4)normally without expanding the hierarchical grid we did not get its children rows. is there any possibility to get all rows without expand

Before the row is expanded the child grid is not yet created on the page Dom. Only after expanding the parent row the child grid is created and instantiated on the page.

So before the row is expanded it is not possible to get the child grids or their rows as they don’t exist yet.

Q5)We hide 2-3 columns for GridModel. but those columns are not able to get in javascript code. So is there any way to hide columns.

In order to hide/show columns on the client side the Column Hiding features needs to be defined for the grid.

http://www.igniteui.com/grid/column-hiding

Then via the features API you can hide/show columns using the related methods (hideColumn and showColumn):

http://help.infragistics.com/jQuery/2014.1/ui.iggridhiding_hg#methods:hideColumn

http://help.infragistics.com/jQuery/2014.1/ui.iggridhiding_hg#methods:showColumn

Let me know if you have any additional questions or concerns.
