How to display picture on base64 Grid column in ASP.NET Core application?
You can display base64 string value as an image in Grid columns by using the ‘column.template’ property and ‘queryCellInfo’ event of Grid component.
This is explained in the following sample code in which the ‘template’ property has been set with an “img” tag to the base64 column. And inside the ‘queryCellInfo’ event handler, the base64 string is bound to the column template element (i.e. <img>) to display the image.
CSHTML
<ejs-grid id="Grid" dataSource="@ViewBag.data" queryCellInfo="queryCellInfo" allowPaging="true"> <e-grid-columns> <e-grid-column field="OrderID" headerText="Order ID" isPrimaryKey="true" textAlign="Right" width="120"></e-grid-column> <e-grid-column field="CustomerID" headerText="Customer ID" textAlign="Right" width="120"></e-grid-column> <e-grid-column field="CityFlag" headerText="Flag" template="<img class='tempimg'>" width="120"></e-grid-column> <e-grid-column field="EmployeeID" headerText="Employee ID" width="120"></e-grid-column> <e-grid-column field="PayGrade" headerText="Pay Grade" width="150"></e-grid-column> <e-grid-column field="ShipID" headerText="Ship ID" width="150"></e-grid-column> </e-grid-columns> </ejs-grid>
JS
<script>
function queryCellInfo(args) { // Grid queryCellInfo event handler
if (args.column.field == "CityFlag") {
args.cell.querySelector('img').setAttribute('src', 'data:image/png;base64 ,' + args.data.CityFlag);
}
}
</script>
