Standard File Queue Appearing Even Though Custom Queue Is Being Used

Reply Quote

Even though I've registered a javascript function on the uploader.handlequeueui property, the standard file queue is still being drawn after the file upload has completed (the one with the checkboxes on the left and the 'remove' link on the right of the table).

I didn't notice anything in the AjaxUploaderDeveloperGuid documentation samples that shows the standard one being disabled.

Should setting that handlequeueui property be enough to disable the standard queue from being rendered? Or is there no way to prevent it from being drawn?

Hi,

Please check this http://ajaxuploader.com/document/scr/create-custom-queue-table.htm

You need return false to cancel the default UI

I do have 'return false;' as the last line in the custom queue javascript function, and there aren't any errors on the page so it shouldn't be failing before returning false.

I'm using a combination of javascript and code-behind though, and from Example 2 I figured out I could use the following property to hide it.

.GetItemsTable().Visible = False

But as far as I can tell, the javascript 'return false;' does not work.

It appears that setting the .GetItemsTable().Visible = False causes the .Items collection to be empty on postback.

Is this the correct behaviour?

I'm also noticing that if I modify the attributes or style collection (trying to set the style "display: none;" on the table for example) of the .GetItemsTable() the .Items collection of the UploadAttachments control is empty on postback.

Hi,

I don't reproduce this issue. Make sure you have the last version.

please try this :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

		base.OnPreRender(e);

//hide the default table
		UploadAttachments1.GetItemsTable().Visible = false;
		//bind the grid every times
		DataGrid1.DataSource = UploadAttachments1.Items;
		DataGrid1.DataBind();
		DataGrid1.Visible = UploadAttachments1.Items.Count > 0;
	}

protected void DataGrid1_ItemCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
	{
		Guid guid = (Guid)DataGrid1.DataKeys[e.Item.ItemIndex];
		foreach (AttachmentItem item in UploadAttachments1.Items)
		{
			if (item.FileGuid == guid)
			{
				if (e.CommandName == "Download")
				{
					using (Stream str = item.OpenStream())

						while (true)
						{
							int rc = str.Read(buff, 0, buff.Length);

								break;
							Response.OutputStream.Write(buff, 0, rc);
						}
					}
				}

if (e.CommandName == "Remove")
				{
					item.Remove();
				}

break;
			}
