I want to Check the checkboxes inside a ListView which is Placed inside a Gridview.The Gridview is having many rows and Each row is having a List view with associated recrods.Each row contains a CheckBox called select all. I want to check the checkboxes of the child ListView control which accompanies that particular Row. I have a Server side code from which Im able to do this. but its taking too much time.. ie almost around 1-2 mins to select records if there are more than 1000 records. I want this to be done using a Javascript. how can i achieve this.
This is the image representing the GridView and ListView.GridView is Groups and Contacts is the ListViewWhen i select the "SelectAll" button in the GridView the Appropriate contacts should be selected.How can I achieve this using Javascript.
