AJAX :: UpdatePanel Not Working For RadioButtonList In Content Page?
Feb 4, 2010
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?
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 got an updatepanel which contains a normal panel on MasterPage. The updatepanel does not contain content place holder. On the content page, I have to add triggers to updatepanel for buttons that are dynamically created on "page_load" event. The problem is that, since the page_load event of content page is being called before master page's page_load event, UpdatePanel is not being created. So that, whenever i try to add triggers in page_load event of content page, i got an error like "A control with ID 'ctl00$editableContent$ctl42' could not be found for the trigger in UpdatePanel 'up1'."
The code below is for adding triggers to updatepanel for buttons.
MasterClass master = (MasterClass)Page.Master; AsyncPostBackTrigger trig = new AsyncPostBackTrigger(); [code]....
</table> </ContentTemplate> </asp:UpdatePanel> <asp:UpdateProgress runat="server" ID="ugLN" AssociatedUpdatePanelID="upLN"> <ProgressTemplate>Image here for showing the progress bar...</ProgressTemplate> </asp:UpdateProgress>
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 want to use Updatepanel on one of the page in website. I have used updatepanel but it does not show any effect of UpdatePanel like Page autorefresh. I have used update panel for whole page, still it got refresh on button click event on the page. what kind of settings I have to do to work update panel on my web-site. Note that: I have added dll reference for AjaxControlToolkit. I don't want to upgrade my website to Ajax enabled website.
Ajax calendar control not working properly with content place holder of Master Page.Most of time Calender Control hides when mouseover with out changing date in content place holder of Master Page.same code works in normal aspx pages.
I am using VWD 2008.. I have a RadioButtonList with two options.
[Code]....
I also have an UpdatePanel
[Code]....
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 java script code to set some of the properties of ajax controls.
the code is working OK If I put it in asp.net page but when I use content page and post the code in part of the code will not work which is changing the value of ajax control properties.
My page has textbox, checkbox, MaskedEditExtender and MaskedEditValidator. when the user check the box the mask property and some other properties should change.
I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.
I have used a radiobuttonlist to enable/disable the textbox in Grid View. I did this using javascript onclick event.
[Code]....
It is working fine when the page get refreshed too.
[Code]....
Then in a scenario, I have removed the radliobuttonlist items (items 2 and 3) dynamically. For the first time when its loaded its working without flaws. After a page is refreshing due to any serverside events, the javascript to enable/disable textbox is not working.
[Code]....
I have verified the HTML file, the radiobuttonlist is loaded without the onclick event.
I got an error of 'RadioButtonList4 is not declared' when putting the codes below in a formview, but the codes can work well in a normal aspx page. Does it need special declaration in formview?
<script runat=server> Public Sub CheckSession(ByVal source As Object, ByVal args As ServerValidateEventArgs) Dim Item As ListItem
I'm having an odd problem. I have a <td> that is set to align it's content in the center. There is a label at the top of the TD that is centered. But then I have an UpdatePanel, and the content of the update panel is not centered. I tried clearing the browser cache, and everything in between but for some reason all of the contents (two GridViews) of the UpdatePanel will not center.
I have a small website that uses 1 masterpage and several content pages. I'm able to insert a <ScriptManager> onto my content pages (just a couple of them). However, when I try to insert the <UpdatePanel>, it won't take it. I tried to wrap the <UpdatePanel> around a <Div> and it didn't like that, so then I tried wrapping the <UpdatePanel> around the actual textbox and it didn't like that. Below is some sample code.
I have an update panel and inside there are a button i want when i press the button the content well be cleared and then a label will be added to the update panel dynamicly and focus that the button is inside the update panel
I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.
I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.
GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.
I'm new at AJAX (that's my first problem - lol)
I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.
