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
MyMasterPage.aspx and content page MyDefault.aspx. MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into TextBox1Default1 at content page MyDefault.aspx, and then refresh UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.
My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008
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.

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.
</table> </ContentTemplate> </asp:UpdatePanel> <asp:UpdateProgress runat="server" ID="ugLN" AssociatedUpdatePanelID="upLN"> <ProgressTemplate>Image here for showing the progress bar...</ProgressTemplate> </asp:UpdateProgress>
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
The subject says it all really. I have a DetailsView which inserts records into a SQL database. It works fine.
When I refresh the page (F5 for instance), I get a dialogue saying such action will resend the data. If I click OK here, the daa does indeed get sent again resilting in duplicate records in my database.
How can I stop data being resent if the page is refreshed?
I have a GridView and DetailsView in a Master/Detail relationship inside an Update Panel.The GridView displays a set of records, and when a Select button in the GridView is clicked, the detailsview displays the record for edit.Initially the focus is on the GridView, and when the Select button is clicked, I want the focus to be on the first TextBox inside the DetailsView. This happens only when I remove the UpdatePanel from the form. If the Gridview/Detailsview pair is inside an updatepanel, the focus never goes to the DetailsView.How can I make the focus on the DetailsView inside an UpdatePanel
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 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.
I want to upload a file INSIDE an updatepanel using the asyncfileupload control. But in the code below the filename is EMPTY! Why?
Protected Sub dvTicketDetail_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdateEventArgs) Handles dvTicketDetail.ItemUpdating Dim afupload As AjaxControlToolkit.AsyncFileUpload = CType(dvTicketDetail.FindControl("afuFlyerEdit"), AjaxControlToolkit.AsyncFileUpload) 'only upload physical file if fileupload control is NOT empty If afupload.FileName <> "" Then 'a new file must be assigned to record End If End Sub
I want to make auto partial page refresh in asp.net. There is UpdatePanel but it sends too much data. So I've found that I can make a webservice and call it by the JavaScript code. But I don't know how to call webservice automatic. There are many examples showing how to call webservice by the button click event:

How to do this by the interval? Am I going in good direction?
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've a Detailsview that contains an updatepanel.A button is pressed within the panel and a window is displayed containing a gridview list.The user selects an item from the list, the window closes and the selected gridview item is placed in "tbResourceID" My problem however comes when the user goes to click insert the validator doesn't fire. I'm guessing this is something to do with the updatepanel isolating the validator.... my code is shown below!
I've implemented a Wizard in which most steps are UserControls. One of these steps contains a DropDownList and a RadioButtonList. Depending on the item selected in the DropDownList, some items in the adioButtonList are disabled or enabled via a callback. This works fine.
Then I added a ToolkitScriptManager to the page (EnablePartialRendering="true") and wrapped the controls in this particular step in an UpdatePanel's ContentTemplate. Running inside of VS2008, the appropriate radio buttons are disabled or enabled as expected in response to changes in the DropDownList without a full page refresh. It feels much more response and looks slick.
Then I deploy to the test server and suddenly the partial-page refresh is gone, the whole page is redrawing as though the script manager and UpdatePanel hadn't been added.
I've tried several variations on this, always with the same result. For instance - I moved the DropDownList outside of the updatePanel and added an AsyncPostbackTrigger for the DropDown's SelectedIndexChange event. No change - works in VS2008 but not on the server. - I added ChildrenAsTriggers="false" UpdateMode="Conditional" to the UpdatePanel, both with the DropDown inside the UpdatePanel and outside the UpdatePanel. No change - works in VS2008 but not on the server.
I am using AJAX TabContainer control with following settings. When I change a tab the postback happens and whole page refreshes. Because AutoPostBack="true"> . To AJAxify the behavior, I added UpdatePanel around it but still the page is refreshing. The control need to go to server because user controls contains some grids which need to be populated.

How can I disable the page refresh and at the same time server side operation happens in this case?
For example, I have master page MyMasterPage.aspx and content page MyDefault.aspx. I have many UpdatePanels at MyMaterPage.aspx, and also I have many UpdatePanels at MyDefault.aspx.

I want JavaScript functionClickMenu(this) at input button [id="ButtonMaster1" @ MyMasterPage.aspx] pass its value ["Menu-1"] into text box [id="TextBoxDefault1" @ MyDefault.aspx], and then performing update / doing post-back to server ONLY FOR UpdatePanelDefault1.
I am looking forward an example code for JavaScript functionClickMenu(this).
