<h3>HTML in Row Details</h3>
<p>
This grid shows product categories on each row. Expanding
the rows shows an HTML element with information about
the products in that category:
</p>
<FlexGrid itemsSource={state.categories} isReadOnly>
<FlexGridColumn header="Category Name" binding="CategoryName" width="*"/>
<FlexGridColumn header="Description" binding="Description" width="2*"/>
<FlexGridDetail isAnimated template={(ctx) => {
var _a, _b;
return (<React.Fragment>
ID: <b>{ctx.item.CategoryID}</b><br />
Name: <b>{ctx.item.CategoryName}</b><br />
Description: <b>{ctx.item.Description}</b><br />
Products: <b>{(_a = getProducts(ctx.item.CategoryID)) === null || _a === void 0 ? void 0 : _a.length} items</b><br />
<ol>
{(_b = getProducts(ctx.item.CategoryID)) === null || _b === void 0 ? void 0 : _b.map(p => <li key={p.ProductID}>{p.ProductName}</li>)}
</ol>
</React.Fragment>);
}}/>
</FlexGrid>
<h3>Grids in Row Details</h3>
<p>
You can add anything you want to the detail rows,
including other grids. This example shows the same
categories, but the detail row uses another grid
to show the products:
</p>
<FlexGrid initialized={onParentGridInitialized} itemsSource={state.categories} isReadOnly autoGenerateColumns={false}>
<FlexGridColumn header="Category Name" binding="CategoryName" width="*"/>
<FlexGridColumn header="Description" binding="Description" width="2*"/>
<FlexGridDetail detailVisibilityMode={state.detailVisibilityMode} maxHeight={state.maxHeight} isAnimated={state.isAnimated} keyActionEnter={state.keyActionEnter} rowHasDetail={state.evenRowHasDetail ? rowHasDetailFn : null} template={(ctx) => (<FlexGrid initialized={onChildGridInitialized} itemsSource={getProducts(ctx.item.CategoryID)} isReadOnly>
<FlexGridColumn header="ID" binding="ProductID"/>
<FlexGridColumn header="Name" binding="ProductName"/>
<FlexGridColumn header="Qty/Unit" binding="QuantityPerUnit"/>
<FlexGridColumn header="Unit Price" binding="UnitPrice"/>
<FlexGridColumn header="Discontinued" binding="Discontinued"/>
</FlexGrid>)}/>
