AJAX :: Associated UpdatePanel To Refresh With New Data Whenever Either Of The Two Dates Is Changed?

Apr 25, 2010

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.

AJAX :: Dropdownlist Selectedindex Changed Will Not Fire And Update Gridview In UpdatePanel?

Oct 6, 2010

I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.

Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)

I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.

It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.

AJAX :: Can't Get The UpdatePanel To Refresh After DB Update

Mar 29, 2010

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

AJAX :: Only One Of 2 Ddl's Causes Page Refresh Within Updatepanel In Detailsview?

Feb 26, 2011

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

AJAX :: How To Make ModalPopupExtender Stay In Each UpdatePanel Refresh

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?

AJAX :: Trigger UpdatePanel Refresh After Page Loads?

Feb 16, 2010

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]...

AJAX :: Check Whether Data Has Changed Without Postback?

Aug 14, 2010

I'm not sure whether or not this is the correct forum...I have been asked to develop a webpage with a very simple table. 10 columns, 10 rows. Each cell will have a dropdownlist. Several people will have this page up at any given time and they will all make changes as needed. I am planning on using a SQL Server
2008 database to keep track of the entries.I need the page to verify the data it contains against the data in the database every 5 seconds or so. If they are different, either the page can refresh or (if possible) the dropdownlist can just change to the correct value.
