If you have many nodes you want to expand, then it is best to set node.expandedtrue directly, and then call api.onGroupExpandedOrCollapsed () when finished to get the grid to redraw the grid again just once.

You can read more about custom CellRenderers in our documentation.Calling tExpanded() causes the grid to get redrawn. To achieve this the example provides a custom cellRenderer for the action column to render the appropriate buttons based on whether the row is in edit mode or not. There is no cell renderer configured, so the grid just places the text for the group into the cell, there is not expand / collapse functionality. All rows that are not this group are blank. Clicking the Edit button will start editing the row and display Update and Cancel buttons instead, which when clicked will end editing and once again display the Edit and Delete buttons. I have a requirement to Display a parent row (data in all columns) with a column dedicated to Group Expand/Collapse Icon. The column Country Group - No Renderer configures the grid to put the Country group data only into this column by setting showRowGroupcountry. When a row is not edited, we display buttons Edit and Delete. Get rows from the server with row groups enabled and expand it on the client without extra request to the server. This is done by prefixing the event name with on, for instance gridOptions.onCellClicked. We add an "action" column in the grid to render buttons to control editing and deletion. All of these grid events are available through the GridOptions interface. Let's take a look at how this is implemented. By default groupDefaultExpanded 0 which means no groups are expanded by default. Refreshing action buttons when row edit starts/stopsÄisplaying the action buttons in a separate column To open all groups down to a given group level use the groupDefaultExpanded grid option as shown below: In the snippet above, all country row groups will be expanded by default as groupDefaultExpanded 1.Displaying the action buttons in a separate column.Open the live example in all the major frameworks using the links below: See the live sample in JavaScript below and links to the same sample in other frameworks just below it. To expand all row groups set groupDefaultExpanded -1. Below are two examples presenting the hierarchy in different. The callback must return a string representing the route, with each element specifying a level of the tree. Please see the illustration below showing this in action: To open all groups down to a given group level use the groupDefaultExpanded grid option as shown below: In the snippet above, all country row groups will be expanded by default as groupDefaultExpanded 1. When providing tree data to the grid, you will need to implement the gridOptions.getDataPath (data) callback to tell the grid the hierarchy for each row. Clicking it a second time (after Year groups have loaded) will cause all Year groups as well as their children Country groups to be expanded - this is a heavier operation with 100's of rows to expand. Doing this when the grid initially loads will expand all Year groups. We have implemented this in live samples in JavaScript, Angular, React and Vue.js. Clicking 'Expand All' will expand all loaded group rows. This functionality allows the user to commit the edits to an entire row as a single transaction or discard the edited values using an easy to use UI. This post shows how to use full-row editing together with buttons to start and cancel editing, commit changes or delete the row. ![]()
