Regarding imageupload in grid

Rohit Rawat posted 12 months ago

Hello everyone,

So , I have to basically add imageupload option in my image column when user edit or add a row and display image normally.But i cant figure out how to do that. I have a controller method which takes Iformfile type image varible and store it alli need is help with grid to upload and how to get that upoad file details to store it in database.

@using Infragistics.Web.Mvc;
@using System.Text.Json

@*@model IEnumerable<GridTransaction.Models.Student>*@
@* The Ignite UI for MVC Grid data source uses LINQ and therefore only accepts instances of IQueryable<T>.
Even when you opt to use the GridMode you will explicitly set the DataSource property which
requires an instance of IQueryable<T> .*@

Hello,

After an investigation I have determined that your requirement could be achieved by using a custom editorProvider. The editorProvider will be an igUpload component and when a new image is uploaded, it will be set as the new value for the cell.

A sample demonstrating this behavior could be found here.

Additionally, more information regarding implementing a custom editor provider could be found in the following topic of our documentation.

Please test it on your side and let me know if you need any further information regarding this matter.
