AJAX :: UpdatePanel Conditional Update OnLoad Event / Updatepanel To Update On Queue?

Aug 25, 2010

i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.

all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.

but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

AJAX :: UpdatePanel And ListView Inside Another ListView - Work?

May 31, 2010

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?

AJAX :: UpdatePanel Doesn't Update Another UpdatePanel?

Jan 20, 2011

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.

AJAX :: Using A User Control's UpdatePanel.Update() From A Page-level Update Panel's Function Call?

Jul 14, 2010

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.

Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.

<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>

This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

AJAX :: UpdatePanel And ListView Events?

Mar 22, 2011

I have a usercontrol with listview control nested inside an UpdatePanel and Panel. Below is the layout:UserControl :: Panel1 -> UpdatePanel -> Panel2 -> ListViewUpdateMode is set to conditional. Panel2's visibility is initially set to false.In the containing page, I load the usercontrol and bind the ListView, turn on the panel2 and call the update method of the updatepanel (since action is initiated by an external button and not a child of updatepanel) which displays the rows successfully. However, none of the edit, select or delete actions execute the intended way. When I click any of those buttons, I can see the
UpdateProgress fine but the events seem to be not firing at all. Execution hits the PageLoad but not into any of those event handlers likeItemEditing, SelectedIndexChanging etc.

AJAX :: Getting Updated Value From UpdatePanel/ListView/TextBox?

Jan 8, 2011

I have a web form for payments which consists of a DropDownList (credit card, purchase order, bill me). By default, credit card is selected, and the form (a ListView within a UpdatePanel) is loaded with the user's billing address. If the user changes the payment option, the form fields change -- for example, if purchase order is selected, the billing address + credit card fields disappear and a "Purchase Order Number" textbox appears. This is done using an AsyncPostBackTrigger associated with an event in the DropDownList.My problem is that when the form is submitted, I cannot see the user-entered values within the UpdatePanel/ListView, but I can see the original values loaded in the ListView before the edits were made. For example, if purchase order is selected, I can see the billing address from the ListView, but I cannot see the newly-entered Purchase Order Number from the ListView.Here's an abbreviated version of my code. I've bolded and commented two lines where the problem appears:

AJAX :: Datapager Displays Wrong Pages After Rebind Listview Using Updatepanel?

Mar 8, 2010

One thing I really don't like about Updatepanel is that I have to rebind almost all components in the page.

For example, I have to specify Eidit (Update) index (for inline editing) after rebind Listview using Update panel (after partial update).

It was too much job to rebind all components, so I redirected to same page and used Querystring to pass values in order to avoid all components to be updated based on one value...

If I update Listview using Updatepanel, the datapager has to be updated as well based on new Select SQL statement results.

Listview is pretty simple to update, using "Listview1.bind()" does the job.

Datapager is also in updatepanel, but it won't rebind with new results.

After post back, I'm still getting same Datapager as the orignal SQLDataSource.

In orger to "refresh" Datapager, what do I need to do??

I used to use iframe to do partial page update, but I'm having big problem using Updatepanel since simple rebind won't do the job.

AJAX :: Trying To Update An UpdatePanel With JQuery?

Jan 29, 2011

I have an UpdatePanel with a MultiView inside. I am using jQuery to call the server to run some logic and based on it, change the view in the MultiView. The problem is that the updatepanel is not getting refreshed.

My UpdatePanel:

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">

This is my call to the server:


When the page loads again, the multiview is not showing the assigned view.

I have noticed that the call to the server doesn't set Page.IsPostback = true, it remains false. Perhaps this is somehow related?

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 :: Updatepanel Does Not Update New Image?

Jan 30, 2011

I am using an updatepanel. Inside this updatepanel I have a LinkButton with the clickevent below.

When clicking this button the Image does not update to a new image. As seen I am assigning the Session variable a new Image path(Session["showThisImage"]) which I am getting in the Page_Load event.

Now I am putting this path in a public variable that is set to the HTML control "Img1" with help of Page.DataBind().

However the Image does not change which is the problem, the image is still there. But other things as labels, links etc do get updated with new data which I haven´t put in this example which means that the updatepanel works except changing the Image here? Also to mention is that if you uncomment: "Response.Redirect("ThisPage.aspx");" the image will change but this will mean a FULL postback which I dont want.

AJAX :: Don't Update Control Within UpdatePanel?

Apr 14, 2010

This sounds weird, but I would like to NOT update a control that's within an update panel. Is this possible? basically the way facebook works, facebook controls are rendered on a "get" command. but I have controls within the same update panel that cause AJAX postbacks. When the postback's happen, I lose my facebook server-side controls. I am wondering if I can "unregister" a control from an update panel? Or do I just have to redesign that page.
