AJAX :: Validator In Updatepanel On Detailsview Doesn't Fire On Post?
Jan 7, 2010
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!
What I did is, I have made 2 user controls. One control is inside the other.
NoW one control has a buttton and a data grid and datalist in it. When pressing button I am filling datagrid while datalist visiblity false. This is working fine. But now when I press some link button in datalist data, it should call item_command event but it is not calling.
I have also used a Updatepanel as a wrapper(all controls are inside it).
I've got a UserControl that's used inside of an UpdatePanel. The UserControl is a fairly simple form that appears via a ModalPopupExtender (which is also part of the UserControl). There are four DropDownLists, as well as some other UI elements. Three of the four DropDownLists have AutoPostBack="true", with SelectedIndexChanged events that fire on the server and cause some of the other DropDownLists to rebind. Two of the three DDL's that AutoPostBack are working fine. One of them, which I only just added, is showing some strange behavior. Let's say I bind five Items to it: 1, 2, 3, 4, 5. I set the SelectedIndex to 0, which makes 1 the selected item. If I select 5 and then 1 and keep toggling back and forth, everything works fine. The postback occurs and SelectedIndexChanged fires. Every time. If I ever select 2 or 4, the postback occurs but SelectedIndexChanged does not fire. Every time.
If I ever select 3, something bizarre happens and sometimes the value of the DDL reverts to 1. Even though breakpoints seem to show that it's not rebinding and no unexpected code is running. I know your first instinct will probably be that I'm wrong about the rebinding code not running, but I have literally been staring at the debugger for hours trying to find my mistake. Lots of breakpoints. I don't get it -- this really isn't that complicated. But obviously I am missing something. I've put about four hours into this so far and I think I'm just grinding at this point. I could use another perspective.
HTML (and by the way, DropProtocolCycleID is the problem control): <asp:Panel ID="PanelPopupAssign" runat="server" Style="display:none; cursor: move; width:325px; background-color:Transparent;"> <BlueUI:Panel runat="server" ID="PanelPatientProtocol" Width="500px" HeaderText="Assign Protocol"> <table cellspacing="5"> <tr> <td style="width:150px;"></td> <td style="width:50px;"></td> <td style="width:125px;"></td> </tr> <tr runat="server" id="TableRowCategory"> <td align="right">Category:</td> <td colspan="2"> <asp:DropDownList runat="server" ID="DropProtocolCategories" CausesValidation="false" autopostback="true"/> </td> </tr> <tr> <td align="right">Protocol:</td> <td colspan="2">..............................
When the user selects an "account" we dynamically create a linkbutton with the selected dates. However, the linkbutton onclick handler doesn't fire when the button is clicked.
Dim linkBtn As New LinkButton linkBtn.Text = "blah" AddHandler linkBtn.Click, AddressOf linkButtonHandler linkBtn.ID = panelDatesRencontre.Controls.OfType(Of LinkButton).Count panelDatesRencontre.Controls.Add(linkBtn) ScriptManager1.RegisterAsyncPostBackControl(linkBtn) Dim Trigger1 As New AsyncPostBackTrigger Trigger1.ControlID = linkBtn.ID Trigger1.EventName = "Click" UpdatePanel2.Triggers.Add(Trigger1)
Answer: i make that in page_load, it seems to work
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.
here is how my grid view looks like and how i add my custom data source to both parent and child grid view. [Code]....
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.
I have a page with two ajax toolkit popupcontrol extenders, both have a Linkbutton inside the popup window, which is inside a panel and updatepanel. The difference is the second one (Linkbutton2) is inside a Gridview, which is also inside a Updatepanel.
The first one works fine, but the second one does not fire when click on it. The code is as follows:
I have a multi view with 2 view in my page. when page is loading first view is set active. by click on a click I set active second view that contain AsyncFileUpload1. but UploadedComplete event doesn't fire. This control works outside of view correctly but into view doesn't work. I have to use multi view and this 2 view in my web page. what can I do?
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:
On Selected Index Change code for each
For the First:
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 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 just wanted to clarify if selectedIndexChanged works on ajax cascading dropdowns as mine doesn't fire. Its in a user control inside an accordion pane. I've read conflicting things about this. All I want to do is check that the last of the 3 cascading dropdowns has been populated an enable a button if so.... but the event never fires when i make a selection on the last dropdown. If it isn't suppose to fire is there a way to raise an event when the selection is made and unmade (as when you change one of the other dropdowns the value resets and the buttton needs to be disabled.
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.
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 have a modalpopup that i have opening on a radiobutton selection. That works great, opens when it should and closes when you click cancel. BUT i have the following on my cancel button event that is not firing
I also have a button event for my "OK" button and that works great, but my cancel event doesnt seem to fire or work. Maybe the ClearSelection() is not what i need..
I want to clear the radiobutton if they cancel out of the ModalPopUp so they can make a new selection, since its a required field.
I am using Ajax Validator call out extender to validate a web form. The error messages are displayed as expected. But I am able to save the form with data that should not have been entered. For ex: for a number field, I type in "sdsd" and the ajax control displays a pop up displaying the error message "Numbers only allowed"..
but at the same time, I can click on the submit button with the text in the number field... at which time, the web page displays error as I am trying to insert a text in a data type int field. I either have to clear the field on pop up error display or not let the user click submit when ajax validator is active. whats the best way?
I have problem when i use UpdatePanel in ContentPage. In Updatepanel, I have DataGrid. Outside, I have a textbox and Button.

<div> Have a textbox and button <updatePanel> Have Datagrid <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.Master" AutoEventWireup="true" CodeBehind="commentForm1.aspx.cs" Inherits="ChatApplication.commentForm1" %>
