AJAX :: Sys.InvalidOperationException: Could Not Find UpdatePanel... On Ascx.page?
Nov 25, 2010
I have three UpdatePanels on my ascx page. In first I have gridview, in second I have DetailView. DetailsView is in a Panel, after click on buttom -Panel show or hide. All works fine. I added third Panel, new Buttom , inside Panel I put UpdatePanel and I would like the some function as in DetailView - show or hide Panel.After click on buttom I can see this error-Sys.InvalidOperationException: Could not find UpdatePanel with ID 'xxxxxxxxxxx. If it is being updated dynamically then it must be inside another UpdatePanel.
I tried many examples, whitch I found on the internet (move Buttom on page - change its position, add UpdateMode="Conditional" to the UpdatePanel), but without any resolution.
I've got a page with two ContentPlaceHolders. In first there is UpdatePanel with GridView. In second I located DropDownList which is trigger for UpdatePanel.
Running the page causes error: "Control with ID 'ATDropDownList" could not be found for the trigger in UpdatePanel". I thought it was because the ATDropDownList is located inside ContentPlaceHolder. So I changed ATDropDownList's ID to UniqueID as follow:
I am running in a critical issue with AJAX Tab Container, Tab Panel. I am using VS 2005 with AJAX extension 1.0 (AjaxControlToolkit.dll 1.0.20229.20821) . Every thing works fine but when my internet is slow it throw the Sys.InvalidOperationException and it is not rendering the Tab Control.Problem i understood is : when Sys.Application.add_init() is executing it is looking for the Owner ID and at that time the owner is absent in the UI as tabcontrol is not yet rendered it still getting the data from the DB. Purposed Solution : After document load if ther owner id is null then re execute the same code (Not a good solution but need to make it work as it is in production server ) however it did not work for me . Please provide me some solution as it is in production. his is the code i am using now but not working .
[Code]....
Using the above solution also did not work , My application is in production ,
i have made a BaseUserControl.ascx and a ChildUserControl.ascxfile. both have its own code behind file.So what i want, i wanted to inharit ChildUserControl.ascx fileto BaseUserControl.ascx. so whatever in my BaseUserControl.ascx fileshould be visible into the ChildUserControl.ascx,means if i have kept a TextBox in BaseUserControl.ascx should be visibleinto the ChildUserControl.ascx desing view. and it should be accessible into the ChildUserControl.ascx code behind file.
1) Is this possible, if yes then how?
2) if above is possible then How to access BaseUserControl.ascx code behind file into the ChildUserControl.ascx code behind file?
Rather strange behavior.I have a web application, which has a aspx page which comrises of master page, user controls, ajax tab control & infragistics grid.This page is opening fine from many clients But this page is not opening on one specific client browser and gives sys.invalidoperationexception: ctl00_ContentPlaceHolder1_tc1 component was not found., with XP & IE 6. Please note that, other client browsers with this configuration in the past never gave this problem. This is the first time in many months I have observed this error.I tried to look for various IE options as well, if it has something to do with scripting setting being enabled/disabled, but could not zero-in on anything specific.Has anyone seen this before and can help me in this regard. Any heads-up on this will be really helpful.
"The type or namespace name 'updatepanel' does not exist in the namespace 'System.Web.UI.WebControls.WebParts' (are you missing an assembly reference?)"
The actual namespace should be System.Web.UI.UpdatePanel. When I go directly into the designer.cs file and change it, it works. However, every time I go back into editing control.ascx and save, Visual Studio always changes it back to system.Web.UI.WebControls.Webparts.updatepanel. I'm not sure what is causing this. Is it how I should be referencing namespaces and classes in my project? I'm using .NET 3.5.
have a problem on my application, i am using LightBox javascript that is using prototype.js library, and when i open any pop up that is having script manager it generate this error:Microsoft JScript runtime error: Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once.I know that is because i have scriptmanager on the parent page that opened the pop up and its something relates to prototype.js but i dont know the connection!
On an aspx page i am having a dropdownlist and a panel control the dropdownlist autopostback is true. in dropdownlist control there are two options and depending on the option selected by the user i display a user control containing ajax updatepanel with a timer configured to launch async request after every one second. the problem arises when user selects the other option in dropdownlist control and the user control gets changed in the panel control. The error which is occured is shown below:
Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_cphMainMasterPage_ChildContent_ctrlPinStatusMonitor_updpnlPinStatus'. If it is being updated dynamically then it must be inside another UpdatePanel.
I thnk the problem is that the last control which have launched the async request is no more available in the panel control and gets replaced by the new other user control.
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 an updatepanel on my master page that just updates the database every 30 seconds, what is happening is that everytime it is fired, it will refresh everything on the page_load of the content page that are not under ispostback = false. to disable such a thing just for this specific updatepanel?
I looked at your example URL....I have ScriptManager in masterpage how call ScriptManager from masterpage in editorPage.aspx if (Script Manager 1.IsInAsyncPostBack)
I have an asp UpdatePanel, an asp panel, an asp timer, and an asp label on my web page, as you know the whole idea of updatepanel is trying to implementing partial page rendering mechanisem, however, it is not the case in my scenario, here is the code:
[Code]....
and on the pageload event, i assign:
[Code]....
strangely, the labl1 does update the time without causing the whole page post back, but the panel does cause the whole page refreshed, and the asp panel contains asp buttons and those buttons are generated dynamically by code behand c# file, am i missing sth here or the nature of asp:panel will cause the whole page post back?
My problem: I have a submit button in my page. The pressed, it reveals a hidden div with updated info and places the page at the right level with an anchor. The div contains a gridview with pages. When I change pages, because of the anchor, I am brought back to the top of the page (if I was at page.aspx#middle, it sends me to a.aspx#). No matter what I do, I can't manage to tell the pages to only update the updatepanel, it always changes the link. I do not have this issue if I don't have a hash, it simply remains at the same place.
What I am trying to do: either not go to the top of the page, or even better, go to the middle of the page, to my #middle tag.
What I have tried: MaintainScrollPositionOnPostback (I need to be able to set my position, so it doesn't work), ClientScript.RegisterStartupScript(Me.GetType(), "BookMarkScript", Script.ToString(), True) (it never worked, never set my page), putting a window.location.hash after my __doPostBack (because it updates my page twice for an unknown reason), ASyncPostBackTriggers (seems to entirely ignore my updatePanel when I am using hashes, even if it works without them).
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 am having now two UpdatePanels on the same content page. One is a big UpdatePanel and another is a very small one. I can insert the little one content to the big one, but it means some info I don't need to update with Ajax at all will be init two, because of UI issues. What is better for performance? One big UpdatePanel or a small ones?
