When providing tree data to the grid you implement the gridOptions.
The callback returns back a string with each element specifying a level of the tree. Below follows two examples presenting the hierarchy in different ways. When the grid is working with Tree Data there is no need to explicitly specify a Column Group as the grid will use the Auto Column Group.
However you will probably want to override some of the defaults as shown below:. As noted above, providing your own Custom Column Group has the advantage of giving you full control over the presentation of the Column Group, however it is not as convenient as using the default Auto Column Group. One significant difference is that the entire dataPath array will be supplied as a value, rather than just the current node value.
The following example combines all the steps above to show a simplified organisational hierarchy:. It is not necessary to include entries for each level in the path if data is not required at group levels as shown below:. The second variation above leaves out row data entries for 'Documents' and 'txt' nodes, in this case the grid will create Filler Groups for these. This following example includes the column 'Group Type' to highlight which nodes are 'provided' in the row data and which are generated by the grid as a 'filler' group:.
When using Tree Data, columns defined with an aggregation function will always perform aggregations on the group nodes. This means any supplied group data will be ignored in favour of the aggregated values. However if there are no child nodes to aggregate it will default to the provided value in the row data.
The File Browser example below demonstrates aggregation on the 'size' column. Also you can refer to the section on Aggregation more details.Multi Step Form With React & Material UI
To override this behaviour to use regular filtering instead, enable the following Grid Options property:. Also note the Set Filter will contain a list of all unique values across each level of the group hierarchy. The following example presents a more complex example which includes Aggregation and Filtering:. It is not possible to do pivot or row grouping while using tree data.
This means all the functions related to pivot eg colDef. If you are showing child counts for the groups, then the child count is a count of all children and grand children. This is different to Row Grouping where only leaf levels are counted, in tree data, all group children are also counted. To enable selection set gridOptions.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Run here command npm install to install the node modules and wait until they are installed. Next run npm start to serve the example and wait until it is compiled shows message in console: Compiled successfully.
The server is needed for the most of the React examples to serve their data. Next run npm start to start the NodeJS server. The destination location can be chosen freely, it just must be accessible for the React server for reading.
In some types of React it must be copied into specific directory, e. It can be also shared among more React projects if the location is accessible for all the project servers.Aggregate values are displayed in the TreeGrid footer and in parent row footer for child row aggregate values.
It can be configured through aggregates property. By default, the aggregate value can be displayed in the treegrid footer, and footer of child rows. To show the aggregate value in one of the cells, use the footerTemplate. The aggregate type should be specified in the type property to configure an aggregate column. Footer aggregate value is calculated for all the rows, and it is displayed in the footer cells. Use the footerTemplate property to render the aggregate value in footer cells.
The aggregate values must be accessed inside the template using their corresponding type name. Aggregate value is calculated for child rows, and it is displayed in the parent row footer. Use the showChildSummary property to render the child rows aggregate value.
You can format the aggregate value result by using the format property. To calculate the aggregate value with your own aggregate functions, use the custom aggregate option. To use custom aggregation, specify the type as Customand provide the custom aggregate function in the customAggregate property. To access the custom aggregate value inside the template, use the key as Custom. Aggregates in React Tree Grid component Aggregate values are displayed in the TreeGrid footer and in parent row footer for child row aggregate values.
To use the aggregate feature, you have to inject the Aggregate module. Built-in aggregate types The aggregate type should be specified in the type property to configure an aggregate column. The built-in aggregates are, Sum Average Min Max Count Truecount Falsecount Multiple aggregates can be used for an aggregate column by setting the type property with an array of aggregate types.
Multiple types for a column is supported only when one of the aggregate templates is used.

The grid creates visual consistency between layouts while allowing flexibility across a wide variety of designs. If you are new to or unfamiliar with flexboxwe encourage you to read this CSS-Tricks flexbox guide.
The responsive grid focuses on consistent spacing widths, rather than column width.
A React Grid/Tree Component written in the Redux Pattern
Material Design margins and columns follow an 8px square baseline grid. The spacing property is an integer between 0 and 10 inclusive. This output transformation function can be customized using the theme. Fluid grids use columns that scale and resize content. Some columns have multiple widths defined, causing the layout to change at the defined breakpoint. The Auto-layout makes the items equitably share the available space. That also means you can set the width of one item and the others will automatically resize around it.
The following demo doesn't follow the Material Design specification, but illustrates how the grid can be used to build complex layouts. The container and item properties are two independent booleans. They can be combined. A flex container is the box generated by an element with a computed display of flex or inline-flex. In-flow children of a flex container are called flex items and are laid out using the flex layout model.
There is one limitation with the negative margin we use to implement the spacing between items. There are 3 available workarounds:. The initial setting on flex items is min-width: auto. It's causing a positioning conflict when the children is using white-space: nowrap.
You can experience the issue with:. In order for the item to stay within the container you need to set min-width: 0. In practice, you can set the zeroMinWidth property:. Truncation should be conditionally applicable on this long line of text as this is a much longer line than what the container can support. Though the Grid component has a direction property that allows values of rowrow-reversecolumnand column-reversethere are some features that are not supported within column and column-reverse containers.
The properties which define the number of grids the component will use for a given breakpoint xssmmdlgand xl are focused on controlling width and do not have similar effects on height within column and column-reverse containers. If used within column or column-reverse containers, these properties may have undesirable effects on the width of the Grid elements.

Progress Dialog Snackbar Backdrop. Edit this page. Grid The Material Design responsive layout grid adapts to screen size and orientation, ensuring consistency across layouts. There are two types of layout: containers and items. Items have padding to create the spacing between individual items.The Grid component can show tree data. In the following example, the data is specified as grouped array. In controlled modepass the expanded row ids to the TreeDataState plugin's expandedRowIds property and handle the onExpandedRowIdsChange event to control the tree data state externally.
Getting Started with KendoReact TreeView
The TableTreeColumn plugin allows showing hierarchical selection controls. You can also combine the TableTreeColumn plugin with the TableSelection plugin to highlight the selected rows and handle the click event on the entire row. You can handle the Grid's tree data state changes to request nested data from the server according to the expanded row ID.
Tree data options are updated once an end-user interacts with the UI. Handle option changes using the TreeDataState plugin's onExpandedRowIdsChange event and request data from the server using the applied tree data options.
Once the page data is received from the server, pass it to the Grid component's rows property. Related Plugins The following plugins implement tree data support: TreeDataState - controls the expanded rows state CustomTreeData - converts custom tree data to a supported format TableTreeColumn - renders the table column with an indent, toggle button, and selection controls Note that the plugin order is important.
Custom Tree Data In the following example, the data is specified as grouped array.
