AJAX :: AsynFileUpload Control Fails On Hidden Panel?
Jun 18, 2010
I have the AsyncFileUpload control within a <asp:Panel> control that I toggle visibility True/False.
For Example when the page loads pnlEdit.visible = False. Then when a user clicks on a detail record in a grid I display the panel with the AsyncFileControl ie: pnlEdit.Visible = True.
Because the the AsyncFileUpload Control is not displayed on the page right away it errors when you try to upload a file. Would anyone know how I could preload the control or configure it.
I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
It works fine in Firefox but in IE 7 fails doing the postback sometimes. Is it just a problem with my browser? The partial postback inside the update panel works great in both browsers, but when I hit the button outside the panel, the complete postback doesn;t work in IE....
I have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.
After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
I then made a reference to the AjaxControlToolkit.dll where it created a new Bin folder and added a whole load of folders below plus the dll file apprears.I've also installed the AJAX tool bar where all the Ajax controls are available.
Then on a new page I added the Editor control which rendered the page as the following
I have a label with a dropdownextender, and below it I have a gridview. When it drops down, it should go on top the gridview , but instead half of it is hidden because it goes behind the gridview. how can that be taken care of?
My Tab Container works fine on my development machine. But it doesn't show up my production machine. On closer inspection, the Production machine renders it as hidden. Any thoughts on why this would happen?
I downloaded and installed AJAX Control Toolkit, following this link
http://www.asp.net/ajaxlibrary/act.ashx.
The tab doesn't show on the Toolbox. I right clicked at the Toolbox and select Show All. The tab and the controls shows up but all controls are gray out, look like disable. How can I make enable?
but when the page is rendered TabPanel is always Hidden,I wateched the html code by Firebug and found visibility is hidden... what is the problem? http://i.imgur.com/m1eSW.jpg
I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a tag with
[Code]....
Server-side Code - [Code]....
I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the , making it visible at initial page render, the control works as expected.
I have two panels on a page. Panel A, and then within Panel A is Panel B. If Panel A's visibility is False, shouldn't Panel B's visibility automatically be false because it's within Panel A?
I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of what im trying to do
this is the javascript error that gets thrown when clicking on the "LinkButton1" link. This error comes from the javascript that is generated by the asp.net ScriptManager control
Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder1_UpdatePanel2'
I am using C# for my programming. I am facing issue, that my hidden variable value is not being updated when it is in update panel. Please see below code for aspx:
and below is the code where I am trying to update one of the hidden field with my CS code. Interesting, when I am trying to debug its showing all the values, however when I see it f on page source it doesn't give any value. Here is my aspx.cs code:
protected void Timer1_Tick(object sender, EventArgs e) { DataTable dtTrips = null; WEX.Prototype.Data.TripDA tripDA = new WEX.Prototype.Data.TripDA(); string tID = hidTripIds.Value; string[] tripIDs = new string[1000]; tripIDs = tID.Split(','); foreach (string tripID in tripIDs) { TripSummaryBO tripSummaryBO = tripDA.getTripSummary(Convert.ToInt32(tripID)); if (tripSummaryBO.tripLastEditedOnDate > Convert.ToDateTime(hidCurrentDate.Value)) { WEX.Prototype.Service.WSProxies WSProxies = new WEX.Prototype.Service.WSProxies(); dtTrips = WSProxies.Build(); Session["AllTrips"] = dtTrips; dtTrips = (DataTable)Session["AllTrips"]; if (dtTrips != null) { if (cnt==0) { hidTripDetails.Value = ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy); } else { hidTripDetails.Value = hidTripDetails.Value + " <br/> " + ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy); } BuildGridViewControl(dtTrips); cnt = cnt + 1; } } else { //upTripsGrid.Triggers.Clear(); PageInit(); } } }
The Ajax control toolkit tab panel automatically inserts a space by all four corners of the body. For example, go to http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/Tabs/Tabs.aspx and look at the TabPanel on the page. The is a space before "Signature:" and "Bio:" labels. How can I set the space-width to 0px; in the tabPanel body?
I use Update Panel in some parts of the page and when the user click on Insert Button, I want to save all the data which is got from the Update Panel's controls. But the data from the Update Panels' controls are not saved in the database. When I debug, the data are in the textbox and hidden field, they are in the Update Panel. But they are not save in the database. Other values, which is not in Update Panel, are saved in the database.
I have an accordion control in my web site. And in one of the panels, I have a drop down list box where, when the user selects an item, it updates the labels right below the ddlistbox. I have it so that it maintains the scroll position when the ddlistbox has an autopostback, but it's very obvious that the whole page posts back. My question is, can I/should I just enclose the ddlistbox and the labels (and a couple of text boxes) in an AJAX update panel? I already have a ToolScriptManager (because of the accordion control), so I don't need to have another script manager, right? I can just put the update panel (with the other controls inside of it) right in the accordion panel, right? Then when the ddlistbox posts back it won't have the delay of the whole page posting back? And it'll still execute the event handler for the listbox selection change? Does this sound right? I'm just looking to make the post back "invisible", and I would like to do a partial postback of just these few controls.
I am trying to wrap my head around update tabels, the thing thats boring me is if i should use one or multiple panels. When i load a control into my update panel should that control have it's own update panel? Or will it use the updatepanel it's loaded into? Is it even possible to dynamicly load a control into an updatepanel and do async post backs from there? Let me paint you a picture:
I have 2 user controls. The first user control generates custom paging and assigns the output as a string literal. The second user control is a simple repeater which uses values from the paging control via a query string to decide which relevant chunk of data to retrn.
The custom paging control is embeded in the custom reapeater control. In my my page, I simply call the customer erpeater control and everything works treat.I now want to add update panels to this but I can't think where to start.
