AJAX :: How To Make ModalPopupExtender Stay In Each UpdatePanel Refresh
Nov 1, 2010
I have a Gridview which is inside a Updatepanel which is updated through a Timer Control every 5 seconds.
So every 5 seconds I get new data in the rows. I am facing an issue in which I want to display the whole mult-line content of my Textbox(es).It displays fine but the modal window disappears after the UpdatePanel is updated.
How do I display this pop-up modal window and make it stay while the UpdatePanel continues to update the rows in the background?
I know I'm missing some simple little thing here...
[code]....
(I put in an Exit Sub at the very top so I'm sure it's not the code).
Essentially, everything is working just great except I need the modal popup to close only if the form data is correct and I choose to close it. The UpdatePanel, "UpdateInfo", is in place to allow form processing without interfering with the UpdatePanel, "UpdatePopup". In my real code, I have a hidden label that I use to report errors. The UpdateInfo is vital for showing/hiding the error but the popup must remain showing...and modal. (I had something like it working once before but I've re-written it since and just can't remember how to do it.)
I try I cannot seem to find a satisfactory solution. As far as I can tell from the documentation a ModalPopupExtender should be able to reside inside an UpdatePanel. However, I simply cannot get it to work.After the first refresh of the UpdatePanel I get errors of various kinds depending on what I've tried.
What I'm trying to accomplish is having a button inside an UpdatePanel which launches a popup. Another button inside the UpdatePanel causes a partial postback. And finally a button within the popup has to cause a partial postback. I have tried at least five different approaches to this problem and finally I gave up and went with a very inelegant solution. I don't think my requirements are all that strange, am I doing something wrong?
First I tried this:
[code]....
This works fine until after the first postback when the Cancel-button (Button4) starts causing synchronous postbacks and the textbox starts to fill up with commas. I also tried the same as above but placing an UpdatePanel within Panel4 (the popup) - no go. Then I tried causing the postbacks in javascript launched from the ModalPopupExtender's OnOkScript - still it starts failing. I tried another couple of attempts all of which failed. Finally I decided to move the ModalPopupExtender outside the UpdatePanel, add dummy buttons and a bit of javascript to launch and hide the popup. Although this satisfies my UI requirements it just plain wrong from a design perspective and it annoys me that I could not get the extender to work inside an UpdatePanel. Has anyone succeded with placing a ModalPopupExtender in an UpdatePanel with the requirements I stated above? Or should it be added to the list of controls that's just not compatible with the UpdatePanel?
I have a menu of buttons inside an UpdatePanel (UPD_Menu) so that buttons can be enabled/disabled without refreshing the entire page. When a user signs in, the Sign Up button is disabled and the Profile button is enabled. Likewise, when the user signs out, the Sign Up button is enabled and the Profile button is disabled.
Inside this UpdatePanel (UPD_Menu), along with the buttons, is a ModalPopupExtender that is fired by the Sign Up button (TargetControlId="BTN_MenuSignUp") that pops up a dialog Panel (PNL_SignupProfile) that contains yet another UpdatePanel (UPD_SignupProfile) that contains a Submit button as well as a Cancel button (CancelControlId="BTN_SelectCancel").
The behavior I am getting is when the user clicks no other button than the Sign Up button, the dialog (PNL_SignupProfile) pops up and is modal. The Submit button closes the dialog and makes the once-hidden panel appear under the menu of buttons. This is not good as only the inner UpdatePanel (UPD_SignupProfile) should be updated without affecting the outer UpdatePanel (UPD_Menu). The Cancel button works as it should by simply closing/hiding the dialog.
If a user clicks any other button in the menu first, nothing happens ( no codebehind yet) but when the dialog (PNL_SignupProfile) is shown, the Cancel button causes the hidden Panel (PNL_SignupProfile) to appear under the buttons. I've tried many different things to no avail...including putting the dialog panel in different places and even controlling the ModalPopupExtender from code.
The only code I have so far is for handling the signin/signout and enabling/disabling the signup and profile buttons based on user signin. There is no code yet to handle the menu of buttons nor the submit button of the popup dialog.
When I have a control within an UpdatePanel which is within a ModalPopupExtender panel, after the FIRST successful display of the modal (by clicking OK), the events of the control are not functioning. I have the full source code below of a working example of this. How do I get around this?In the sample, when the modal is first opened checking and unchecking the checkbox updates the textbox. Clicking OK updates the textbox in the outer UpdatePanel. Opening up the modal a second time will now prevent the checkbox from updating the textbox.
I have recently updated ajax control toolkit from 30512 to 30930 (same applies to latest version of ASP.Net Ajax Library) and came across a reproducable problem.For a long time I used to have a control with ModalPopupExtender & RoundedCornersExtender which was placed inside of an UpdatePanel and everything worked great up until recently.
Now I'm getting "Microsoft JScript runtime error:Sys.InvalidOperationException: Two components with the same id 'rce' can't be added to the application." during an async postback.Click on button "Wait" and error comes up every time.
Now if you click the "toggle" button div tag id sub3 will display. If you click different button div tag blah will display.If you click refresh then both the toggle and different div tags disappear. Is there a way so that when you click refresh that the both div tags stay visible through the postback?
i hope to add a popup panel in the child page. however i find that when i move the panel, the location is not right and the reason is the master page have some area which cause the location is not exactly right .for example, the panel is on x,y=10,10. when i click the panel, it jump to x,y=10.50.
I have a simple ListBox and a Ajax File Upload control. I have these controls within an Update panel. But I cannot get the ListBox to update upon uploading a new file.
I am dynamically ading the following to an UpdatePanel
Tab control which has X# of Tabs, each Tab has a various labels and a Rating Control.
When the user hits the Rating contro, the RATING_Changed fires and runs a stored Proc to update the DB. I want the Panel to then display the newest information back from the DB. I can't seem to get the last part to work. I'm still learning .NET so i may have missed somethign easy, but i've tried setting AutoPopstback, using Triggers, etc.
The DB Update does take place but the NEW contents are not displayed
I have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).
Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.
Here's the code:
[Code]....
On Selected Index Change code for each
For the First:
[Code]....
For the Second:
Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel") Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg") If ddlModel.SelectedValue = "Add" Then 'Add New Record txtDDLName.Value = "ddlModel" txtDtlsViewName.Value = "dtlBikes" txtItemType.Value = "BikeModel" txtParentID.Value = ddlMfg.SelectedValue txtNewItem.Text = "" txtNewItem.Focus() lblNewItem.Text = "Enter New Model:" modInsertItem.Show() End If End Sub
I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.
Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.
<code> <%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestUpdate.aspx.cs" Inherits="TestUpdate" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> [code]...
I got strange behaviour here. My environment is VS.Net 2008 Team server and I tried to use updatepanel but failed.
[Code]....
When I clicked the button, I expect Label3 inside updatepanel to be updated and Label2 remained the same, AND of course without page refreshing flick. But the result is page is completed refreshed and both labels are updeted.
I am using AJAX extension in visual studio 2005. First of all i am created a Web custom control which contains Dropdown list. I have also set AutoPostBack="true" for getting its SelectionEventChange event.
I am added this web control on another page inside a UpdatePanel.(i added dynamically on another page).
I have a page that displays data depending upon the date range entered by the user into two textboxes. I have added the CalendarExtender control from the Ajax Toolbox to each of these two textboxes, and I would like the associated updatePanel to refresh with new data whenever either of the two dates is changed. Sounds simple enough, but I have not been able to manage it so far.
</table> </ContentTemplate> </asp:UpdatePanel> <asp:UpdateProgress runat="server" ID="ugLN" AssociatedUpdatePanelID="upLN"> <ProgressTemplate>Image here for showing the progress bar...</ProgressTemplate> </asp:UpdateProgress>
protected void OnRatingChanged(object sender, RatingEventArgs e) { SqlConnection con = new SqlConnection(connStr); SqlCommand cmd = new SqlCommand("Insert into rating(rating,postid) values(@rate,@pi)", con); cmd.Parameters.AddWithValue("@rate", e.Value); cmd.Parameters.AddWithValue("@pi", Request.QueryString["ID"]);
[Code] ....
The rating value get inserted to database async but updated rating is not displayed after update. I have to refresh page in order to display updated ratings.
I have a popup window of course through the use of modalpopup extender that searches a record. In the popup window, I have two buttons - a search and a close button. Whenever, I click on the search buttton, the popup window immediately disappear. How am be able to make my modal popup window to stay visible even I click on the search button?
Note.Using this on master page.Ok.After trying for hours i cannot get it to work.I need the footer to stay on the bottom of the screen.This is exactly what i want but i does not work(footer stays where content ends). URL.... My page structure is this:
I am trying to add validation on my form. I am using AJAX controls in my form fields. When I remove the Update panel and AJAX control, my validation starts working, but when keeping both the things together, my validation is not working. How could I make them work together?
<script type="text/javascript"> function Validate() { var QuestionTextArea = document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion"); varError = ""; if (!IsTextBoxEmpty(QuestionTextArea, " Question Text Area not be Empty.")) { alert(varError); document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion").focus(); return false; } return true; } </script> <asp:UpdatePanel ID="UpdatePanel2" runat="server"> <ContentTemplate> <asp:TextBox ID="txtQuestion" runat="server" MaxLength="1000" Columns="50" Rows="5" Style="width: 380px; float: none" Text='<%# Bind("Description") %>' TextMode="MultiLine" /> <AjaxControl:TextBoxWatermarkExtender runat="server" TargetControlID="txtQuestion" WatermarkCssClass="water" WatermarkText="Type your Question Here."> </AjaxControl:TextBoxWatermarkExtender> </ContentTemplate> </asp:UpdatePanel>
When I removes ajax extender and Update Panel. My textbox gets validated and when using UpdatePanel. No javascript function created by me is called.
I have a problem and i have been stuck on it for a while now: I have a ListBox generated dinamically on the page at the first init of the page. That part of the page will never make a postback again while being used.
Say i have 10 UpdatePanels in the same page and there will be a maximum of 10 ListItems in my ListBox. How can i make every ListItem in the ListBox be a trigger for my existing UpdatePanels , so that when i doubleclick one ListItem , the apropiate UpdatePanel will be updated ? Or if you have any other close solutions.
i have a DropDownList, which is inside an UpdatePanel. Now my problem is that, for example, lets say there are 3 item, Item1, Item2, Item3.
Now Item1 is the default, and i have code in codebehind that gets the value of the selected DropDownList, so for example, my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString; string insertSql = "UPDATE Items SET ItemSelect = @ItemSelect"; using (SqlConnection myConnection = new SqlConnection(connectionString)) { myConnection.Open(); SqlCommand HubInsert = new SqlCommand(insertSql, myConnection); HubInsert.Parameters.AddWithValue("@ItemSelect", DropDown1.SelectedValue.ToString()); HubInsert.ExecuteNonQuery(); myConnection.Close(); }
Now the problem is that, once it is in an update panel, when you change the list to another item, so for example, i changed the list to "Item2", it will still be showing the first value of "Item1", i could have used Autopostback to get what i need, but then i wouldnt see the point in using update panel, since i dont want my page to flick.
Is there a way, or code to write that whenever the value of the DropDownList is changed, and i click my button, it will actually get the currently selected value, and not the virst default value,
