Hello everyone,
Thanks for reading my question.
I've created a Field of type File and place it on the form (model driven app). I need to do basic validation of the file such as File extension and File content. Now, with the help of Dataverse REST Builder I've the code to find the file name/extension & file content but the challenge is if I run the code on the fieldOnChange then the needed information doesn't exist in the database by the time. So, I need to find some other event on which I can trigger the code.

Reportthis.fileToProcessOnChange = function(executionContext){
prg_DataTransfer.checkFileExtension(executionContext);
}
this.checkFileExtension = function (executionContext){
$.ajax({
type: "GET",
url: Xrm.Utility.getGlobalContext().getClientUrl() + "/api/data/v9.2/prg_temporarydatas(cfb732f7-7acd-4193-9bfc-d4b352669f1c)?$select=prg_filetoprocess_name",
headers: {
"OData-MaxVersion": "4.0",
"OData-Version": "4.0",
"Content-Type": "application/json; charset=utf-8",
"Accept": "application/json",
"Prefer": "odata.include-annotations=*"
},
async: true,
success: function (data, textStatus, xhr) {
var result = data;
//console.log(result);
// Columns
var prg_temporarydataid = result["prg_temporarydataid"]; // Guid
var prg_filetoprocess_name = result["prg_filetoprocess_name"]; // Text
console.log("File Name: " + prg_filetoprocess_name);
},
error: function (xhr, textStatus, errorThrown) {
console.log(xhr);
}
});
}Hi @zohaibukhan
Unfortunately, the current control does not support a validation. Indeed, once you load your file on the UI, the file is automatically loaded in the database.
I managed once to manage the validation of a file type column using a plugin. I think it's the best way to do this kind of validation.
Also, I hope we will have the possibility to create PCF controls for this type of column. This will give more flexibility in the future.
