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 :: How To Change UpdatePanel Content From Another UpdatePanel

Jun 23, 2010

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 4, 2011

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 :: 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 :: Gridview Within Updatepanel Not Triggering Gridview Outside Of Updatepanel

Jan 14, 2011

I have a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup. Initially the gridview merely displayed saved records you personally choseto save, well when you selected one, the popup would close and the data from that row would be passed to the gridview within the page to display details.. no issue when it was setup that way.. well eventually it was decided to add a delete option within themodal popup gridview so now when viewing the records you can delete it if not needed. works well.. but now with the updatepanel surrounding the gridview when i click on my "select" link it doesnt execute my

AJAX :: How To Use ModalPopupExtender In UpdatePanel

Feb 5, 2010

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 :: PopupControlExtender And UpdatePanel?

I know this may be easy, but I have looked at it for a bit of time and maybe my brain is going in circle.OK, I am learing PopupControlExtender. Looks like it is a good thing to have. One (style of) example is to have a TextBox. Click on it and the PopupControlExtender will come up. Sample code may be like the Example 1 in this



Why there is a need to put UpdatePanel inside the Panel? It is the TextBox which needs to be updated. Why the TextBox is not put into an UpdatePanel? (I try Example 1 and it works without having to put the TextBox inside an UpdatePanel.)

AJAX :: UpdatePanel Add Value To DropDownList?

Mar 17, 2010

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!.

AJAX :: Updatepanel Not Working

Feb 11, 2011

I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.

ScriptManager in the masterpage:

AJAX :: Add Tab Via Click, Using UpdatePanel?

Jan 21, 2011

I am trying to have a TabContainer with a dynamic/changeable number of tabs: when the user clicks on the last tab labeled "New", a new tab is added to the list. There are two issues:

1) The tab container's ActiveTabChanged event fires twice, adding two tabs. Why is that?

2) Any further clicking on the tabs gives an error, "There is no source code at the current location." How is that possible?
