Ajax Nested Datalist In Updatepanel

Oct 27, 2010 11:24 AM

I need to input nested data (data entry) and i am using datalists for the same. The details include many details and I am managing the same using controls for each in information.The parent datalist can have max 20 rows with 7 rows in each child datalist. I tried to bind the datalists with max rows, due to which the rendered page size was almost 12MB and it took more than 2 mins to load.Alternative to this, I put the parent datalist in updatepanel and bound it to one row initially. Onclick of add button, i implemented an asynchronous postback to add new row to the parent datalist datasource and update the updatepanel to display the datalist. The new row is displayed properly in datalist, however it gets reset to original datalist after some seconds.

Nov 01, 2009 09:08 PM

I've created a Page where the user can manage your own photo. To present the Photo Collection i've used a DataList Control inside an UpdatePanel for avoid a postback action; the code is below:

In my page I use javascript to Hide and Show 3 div and at the first Page Load I show only a div which user use to insert a photo and hide the others such as div to update the photo. The User will have to select a gallery again and then he will see the page selected into paging before. How can i solve this problem? I use the PagedDataSource like below:

Forms Data Controls :: Refreshing Datalist In Updatepanel?

Sep 22, 2010 01:28 PM

I have a datalist. When a user clicks a button in the datalist I change some properties and then want to refresh the datalist. However, the code below doesnt seem to refresh the datalist. Once I reload the entire page (which I dont want) the changes are visible in the datalist. I also tried setting the updatemode of the updatepanel to "Conditional" and update manually in the dlPhotos_ItemCommand, but that doesnt work either.

In bold I've marked where I want to refresh the datalist

<asp:UpdatePanel ID="upnlPhotos" runat="server">
<cc1:AsyncFileUpload ID="afuPhoto" runat="server" />
<asp:DataList ID="dlPhotos" DataSourceID="dsPhotos" DataKeyField="id" RepeatColumns="5" RepeatDirection="Horizontal" GridLines="None" runat="server" >

AJAX :: UpdatePanel Doesn't Update Another UpdatePanel?

Jan 20, 2011 09:47 PM

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 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.

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel

Mar 04, 2011 04:40 PM

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?

AJAX :: Cannot Use UpdatePanel Within UserControl Within UpdatePanel

Feb 25, 2007 09:22 PM

If the title was too confusing, here's a breakdown of the problem I'm having:I have a page with an UpdatePanel in it. Within that UpdatePanel, I dynamically load the .ascx file. This UserControl has a static UpdatePanel within itself.The page technically works, although I'm sure the wiring up behind the scenes is NOT correct -- the only way to get it to work (most of the time) is to dynamically load the UserControl both everytime the page loads, as well as every time a trigger occurs.

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

Aug 25, 2010 08:09 AM

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 :: Multiview Inside Updatepanel, Updatepanel Inside View?

Apr 25, 2006 08:41 PM

Has anyone gotten this to work? I have a multiview inside an updatepanel, and I can switch tabs without a screen repaint. But then, in one of the views I tried to put an updatepanel to update something in that view and it started freaking out. (probably for similar reasons to the freakout when I tried to put an updatepanel inside the itemtemplate of a repeater)

For example, I want a view to enter billing information, but then I want to dynamically hide the states dropdown if you pick a country other than US, CA or AU. At first it told me that my trigger had to reference a valid control, so I set it to the name of my country dropdownlist. It accepted that but then it gave me an object expected javascript error. Quite frankly, my brain is about to explode from trying to wrap it around this stuff.

So, I'm going to skip the idea of hiding the state DDL and just have a default option "select if appropriate" and move on with my life. But consider this an FYI to you boys (and girls) on the atlas development team.

AJAX :: How To Use ModalPopupExtender In UpdatePanel

Feb 05, 2010 12:13 PM

I try I cannot seem to find a satisfactory solution. As far as I can tell from the documentation a ModalPopupExtender should be able to reside inside an UpdatePanel. However, I simply cannot get it to work.After the first refresh of the UpdatePanel I get errors of various kinds depending on what I've tried.

What I'm trying to accomplish is having a button inside an UpdatePanel which launches a popup. Another button inside the UpdatePanel causes a partial postback. And finally a button within the popup has to cause a partial postback. I have tried at least five different approaches to this problem and finally I gave up and went with a very inelegant solution. I don't think my requirements are all that strange, am I doing something wrong?

First I tried this:


This works fine until after the first postback when the Cancel-button (Button4) starts causing synchronous postbacks and the textbox starts to fill up with commas. I also tried the same as above but placing an UpdatePanel within Panel4 (the popup) - no go. Then I tried causing the postbacks in javascript launched from the ModalPopupExtender's OnOkScript - still it starts failing. I tried another couple of attempts
all of which failed. Finally I decided to move the ModalPopupExtender outside the UpdatePanel, add dummy buttons and a bit of javascript to launch and hide the popup. Although this satisfies my UI requirements it just plain wrong from a design perspective and it annoys me that I could not get the extender to work inside an UpdatePanel. Has anyone succeded with placing a ModalPopupExtender in an UpdatePanel with the requirements I stated above? Or should it be added to the list of controls that's just not compatible with the UpdatePanel?

this is my final solution:

AJAX :: A Bug With Either ModalPopupExtender Or UpdatePanel?

Dec 01, 2009 07:40 PM

I have a panel, a button, and a ModalPopupExtender that links the two. I then have both of these in an UpdatePanel along with another button control (let's call Button2). Every time Button2 posts back, the textbox in the popup panel has its value changed. E.g. if the value was "ABC", it will become "ABC,ABC". And it will keep changing upon each postback as "value,value" so after a couple postbacks it will become "ABC,ABC,ABC,ABC" so on and so forth. If the textbox is empty, it will accumulate commas. I have no code and no script in my code that changes the value of the textbox. If I take the ModalPopupExtender code out, then this doesn't happen so I imagine it has something to do with a combination of the modal popup extender and the update panel. Not sure where the problem lies. Here's a simple page that reproduces this problem. Click on the button called "Postback" and view the popup, then click again and open the popup again. Notice the commas. I'm using ASP.NET Ajax Library Beta version 0911.

AJAX :: UpdatePanel Add Value To DropDownList?

Mar 17, 2010 10:16 AM

I have a page with an UpdatePanel wich inside has a dropdownlist control. Everything on the page is created dynamically on Page_Init.

DropDownList items are taken from the database with a Select based on some table.

I want to click a button inside the drop down list that inserts a new row in the table that dropdownlist control is based on, and then, on another postback I want the item to appear in the dropdownlist and select it.

On the first button click I insert my row. Ok. On the second button click (I just want to do a postback), in Page_Init I check that the dropdownlist control contains the item I have inserted, and it is there. But in Page_Load event of the same postback I want to set the value selected to be the new value,
but now the drop down list doesn't contain the item anymore!.
