RadAsyncUpload in Grid

I noticed this on the Upload example:

"You need to ensure that any submit buttons on the page are disabled while upload is in progress. Otherwise, there is no guarantee that the files will be uploaded successfully"

How would I do that?

Hi Marty,

A possible solution is to find the buttons on the page by using a JavaScript and set their disabled attributes to false. Please check out the following code snippet.
document.getElementById("btnPlaceOrder").disabled = true;

Kostadin,

I know how to disable a button?? What I would like to know is how to disable a button until an image is selected and uploaded via the async uploader.

Seems the example code for upload in a grid is not complete. Surely you would have a way of doing what you recommend by saying "You need to ensure that any submit buttons on the page are disabled while upload is in progress. Otherwise, there is no guarantee that the files will be uploaded successfully".

Thanks, Marty

Hello Marty,

A possible solution is to disable the buttons on OnClientFileUploading event handler and enable them back OnClientFileUploaded. Please check out the aforementioned help articles for additional information.

How do I find a reference to the update and cancel button in the EditColumn via JavaScript so I can disable/enable?

<EditFormSettings>                           
                            <EditColumn ButtonType="PushButton" CancelText="Cancel" UpdateText="Update">                               
                            </EditColumn>
                        </EditFormSettings>

function OnClientFileUploading(sender, eventArgs) {
                            var update = ($("input[id$='UpdateButton']").length) ? $("input[id$='UpdateButton']").prop('disabled', true) : '';
                            var insert = ($("input[id$='PerformInsertButton']").length) ? $("input[id$='PerformInsertButton']").prop('disabled', true) : '';
 
                        };
                        function OnClientFilesUploaded(sender, eventArgs) {
                            var update = ($("input[id$='UpdateButton']").length) ? $("input[id$='UpdateButton']").prop('disabled', false) : '';
                            var insert = ($("input[id$='PerformInsertButton']").length) ? $("input[id$='PerformInsertButton']").prop('disabled', false) : '';
                        };


here is what I did. I am sure there must be a better way to identify the buttons than this? I've used the jquery selector ends with to find the buttons.

Hi Marty,

You could use the following approach to disable/enable the update and cancel buttons.
function OnClientFileUploaded(sender, eventArgs) {
    var cancelButton = $telerik.findElement(sender.get_parent().get_editItems()[0].get_editFormItem(), "CancelButton");
    var updateButton = $telerik.findElement(sender.get_parent().get_editItems()[0].get_editFormItem(), "UpdateButton");
    cancelButton.disabled = false;
    updateButton.disabled = false;
}
 
function OnClientFileUploading(sender, eventArgs)
{
    var cancelButton = $telerik.findElement(sender.get_parent().get_editItems()[0].get_editFormItem(), "CancelButton");
    var updateButton = $telerik.findElement(sender.get_parent().get_editItems()[0].get_editFormItem(), "UpdateButton");
    cancelButton.disabled = true;
    updateButton.disabled = true;
}
