I have a file upload control in which i want to restricr the users not to upload more than 1mb file. Is it possible using custom validator or any other code. I want to raise validation before any postback happends.
View 2 RepliesMy application allows a user to upload a file using the FileUpload control. The data contained in the uploaded file is then displayed to the user in a Grid for review if certain field validation criteria is met otherwise, a message is displayed stating that invalid data was encountered. If the data displayed is satisfactory, they have a 'Process Data' button to add the data to the system.
Initially, I used a simple If/Else block to determine if there was a file selected or not and if not, display a message to the user. As the coding got more complicated, this stopped working and I was told to use the RequiredFieldValidator control instead to get around the issues that arose.Now, I have a new issue: after the uploaded file data passes field criteria validation, the FileUpload box is cleared automatically and so when the user clicks the 'Process Data' button, the VC throws a message stating that the file name is missing from the FileUpload box.
