AJAX :: UpdatePanel : Functionality That Would Be Like ParentAsTrigger=false?
Feb 16, 2010
Here's my situation:I've got a parent UpdatePanel (with ChildrenAsTriggers set to false and UpdateMode set to conditional) that contains a webpartzone which loads webparts with user controls inside them at runtime. Both the parent UpdatePanel and the child UpdatePanel (also set to ChildrenAsTriggers=false and UpdateMode=Conditional) obviously have triggers set up that are relevant to them.
The problem is that whenever the parent UpdatePanel fires an asynchronous postback, the child UpdatePanel in my user control gets fired off as well thereby causing my user control to be re-rendered. I don't want this to happen. Outside of initially loading the user control, I want that user control to only get updated/rendered again when a trigger inside itself is fired,not when the parent (outer framework) fires off one of its triggers. A ParentAsTrigger property (set to "false") for the child UpdatePanel would be perfect if it existed.
Note that I've tried eliminating the child UpdatePanel inside the user control and then loading the triggers for those controls to the parent UpdatePanel at runtime, but that doesn't work because the user control is being invoked within CreateChildControls() -- I get an exception when I attempt to do that.
I am developing an asp.net web application and stand on jQuery plug-ins for any aspects of my Interface. But unfortunately I have to use AJAX only for its UpdatePanel to enable partial rendering. Is there any way to use jQuery for partial rendering and act such an UpdatePanel?
I am using updatepanel with visible property set to false and on selection of checkbox i am setting updatepanel visible true but i am getting error when i make updatepanel visible to true.If some one know the solution of this problem please do let me know.
If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.
In my form I have a label and button control.By default the label is visible. When a user clicks on the button I have made the label to visible false.For simple button it is working, but when I add an updatePanel to button the event is getting fired but the label is not getting to visible false. this is happening and the solution for this.
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 web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
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 am trying to figure out what is the best way to go about creating functionality like this[URL]with ajax. I am just looking for the clock countdown functionality and the constant seamless update of the price.
My issue is once I click my confirm button I don't get the cool functionality that the ConfirmButtonExtender is suppose to give. Instead I get a the same old plain jane messagebox. Is there something in particular I need to set to make it work?
I'm considering going at this myself because my requirements are particular and highly customized:
The grid is bound to a collection of complicated objects, each of which may contain child and grandchild objects. Depending on data and context, the template'd cells vary from TextBoxes to ComboBoxes to Calendars to a combination of controls.TextBox cells have Google-style auto-complete functionality. Also each TextBox cell can expand into a small TreeView pane that allows hierarchy-navigating selection of a value should auto-complete be insufficient.Values from other controls can be drag-and-dropped into cells.Columns are re-sizable and re-orderable. Clicking their headers sorts data.All of the above is AJAX / client-side / Web 2.0 of course.
Has anyone built anything similar from scratch? Or used an effective tool to accomplish this goal? How well would Telerik meet my specs? Is it right to have the hunch that something this specific is best done by taking a Microsoft GridView and extending it myself?

I ran an ASP.NET page that i have under development on my local IIS. It uses some dragPanelExtenders as well as some other AJAX Control Toolkit AJAX client side stuff, and in order to show the page to somebody, I wanted to put it up as a plain HTML file, hosted on a live web server (running APACHE). (This is the only public web server I have access to, and I want them to be able to drag some panels and experience the page as it would be when "live")
So, I viewed the page running on my local IIS, then saved the source as a HTML file.
Then copied this HTML file to the web server ( as well as necessary CSS, JS and image files).
When I view this HTML file through the web server, I get this error :
ASP.NET Ajax client-side framework failed to load.
By debugging, I see that the following lines were in my saved HTML :
So, at runtime, the referenced resources "ScriptResource.axd" and "WebResource.axd" were not found.
Is there any way to get whatever is needed from those AXD's to my HTML file, without actually executing anything on IIS?
I have not yet done a deep dive into the Toolkit code. I need to try and make a couple of changes to the Calendar. The first one feels like an "it can't only be me that needs this" problem. I have EarliestDate and LatestDate parameters floating around. The requirement is to prevent the user clicking (ie they display as text rather than hyperlinks) any dates which fall outside of the two date limits.
An extension of that (not essential, more of a luxury) would be to prevent the user moving to months or years where the dates within that month/year are completely outside of the allowable range. The second one relates to when the initial view of the Calendar is Years. I need to either be able to specify that the initial display starts for a given historical year (without showing that year in the textbox); or [better] to be able to squeeze a larger number of years onto the display, so that the user can move back a greater number of years with fewer clicks.
