AJAX :: Using A RadioButtonList To Update An UpdatePanel?
Jun 8, 2010
I'm having trouble getting a RadioButtonList to correctly trigger the OnSelectedIndexChanged command. I've set AutoPostBack to true, and I've registered the control for AsyncPostBack. It triggers once, but then it won't again.
I am using VWD 2008.. I have a RadioButtonList with two options.
I also have an UpdatePanel
When the LoadingOption change it then has some code behind that at the moment changes the <asp:Literal ID="ItemName" runat="server" /> text.
If I don't have a Radiobutton selected when the page loads then all works fine. i.e. I can select either radiobutton and the ItemName updates correctly.... Whats the problem you may ask ????
Well I want to have one of the Radio buttons selected when the page has been loaded (like a default setting). So I do this <asp:ListItem Text="1kVA" Value="1kVA" Selected="True" />........ Here is my problem, When I select the other option (7kVA) the ItemName updates fine BUT if I then select the first option (1kVA) the ItemName does not update. I added another button that just does a postback. When the button is clicked the ItemName updates correctly. OK, fine but I don't want that. I want to be able to click on one option and the ItemName updates then click on the other option and the ItemName updates.
Have I missed something out ??
By the way if I set the <asp:AsyncPostBackTrigger ControlID="LoadingOptions" /> to <asp:PostBackTrigger ControlID="LoadingOptions" /> then it works how I want it apart from the reloading of the page, I would like it to update in Async Mode so it is seemless and no page reload.
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.
I have the same problem as [URL] However, the solution doesn't work for me since I'm using .Net 4.0 and xhtmlConformance is not there from start.
Basically, using a master page, the RadioButtonList still do the whole page postback even it's in the UpdatePanel. When I put the exact same code in a standalone page without a master page, it works as expected.
I have a radiobutton that triggers the updatepanel to display or not..
when the page loads, i can select yes adn it displays, i can select no and it disappears.. i hit yes it reappears.. but after like the 3rd time going back and fourth testing the functionality, it stops displaying all together.
Is there something i need to look at to find out what is going on?
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'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.
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.
I am having a weird issue with the update panels. I have an update panel in UpdateMode = Conditional . I have a dropdown list and a grid view..the gridview has to be updated Ã–nSelectionChanged event on the dropdown.
The issue here is on changing the selection on dropdown, the onselectionchanged event is triggered, new data is grabbed, bound to gridview..but does nt update the update panel even after the updatepanel.update();
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.
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
how to update treeview using updatepanel?I am binded my treeview using xml datasource,periodically the datasource was updated,so i am used updatepanel in treeview but, it is not updating while changes came.when i refresh that page ,it is update
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.
ScriptManager exist in MasterPage. I registered trigger by timer.I want to update color of rectangle in Map.aspx. but It is not update. If use Label instead of Image Control, update is done. - structureDefault.aspx have table. table have cell. cell have usercontrol. usercontrol have updatepanel.updatepanel have image control. image control have Draw.aspx in ImageUrl.- Code Sample1. MasterPage behind Code
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.
i have a Textbox and a few update panels. But each time the update panel clicks, then the focus on the textbox is gone So for example, we all know that when a user clicks on a textbox, there will be a blinking | symbol. But each time my panel updates, the focus on the textbox goes. Does anyone know how i could keep the focus on? as in, each time there is an update, still keep that textbox | symbol blinking.
