AJAX :: Use Updatepanel With Dyanmic Controls?

Apr 13, 2010

I have created a user control(.ascx) and i am loading this control on .aspx page at runtime using LoadControl() method ==='Codeing on .aspx page' Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit Dim Item_1 As Control Dim objLoad As New System.Web.UI.UserControl Item_1 = objLoad.LoadControl("~/Controls/CmbList.ascx") Rpt_Panel.Controls.Add(Item_1) Dim Item_2 As Control Dim objLoad_1 As New System.Web.UI.UserControl Item_2 = objLoad_1.LoadControl("~/Controls/CmbList.ascx") Rpt_Panel.Controls.Add(Item_2) End Sub My .ascx control contains a combobox and as shown in above code, i am loading this control twice on my page. Now i have implemented a functionality that whenever item is changed in Item_1 combo, values in Item_2 will be loaded based on value selected in Item_1. this works fine but whenever item is changed in Item_1, the whole page get refresed. I want to use AJAX here so that on Item_2 combo gets refreshed. Can anyone help me how can i achieve this? And if possible i want to implement this behaviour in my .ascx control rather than on .aspx page.

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 :: Controls Disappear In UpdatePanel?

Sep 10, 2010

I have an update panel and inside the update panel I have a button. When I click that button I want to show textbox which is hidden (i.e. style="display:none"). I want to do it from client side. I wrote a javascript to show the textbox. But the textbox disappears after it is shown.

my button code looks like this: <asp:ImageButton id="b1" OnClientClick="showTextBox();">.

showTextBox() code is called and it displays the textbox, but the click event goes to the server and comes back and when it comes back it doesnt know about the newly added textbox i guess. Is there an easy way to show the textbox from the client side without going to the server inside UpdatePanel.

AJAX :: Affect Controls Outside The UpdatePanel?

Jun 4, 2010

I have a web page with an UpdatePanel containing two GridViews and related controls. There is a Save button on the page outside the UpdatePanel. One of the event handlers for a control inside the UpdatePanel calls a method DisplaySaveButton, which is supposed to make the Save button visible or not depending on a parameter. Although DisplaySaveButton is called & executed correctly, it does not effect the visibility of the Save button.

If I remove the UpdatePanel from the form, leaving all its content behind, everything works perfectly.

how do I affect the state of a control outside the UpdatePanel?

AJAX :: Refreshing Controls Outside An UpdatePanel?

Everything is working great, except during one of the PostBack from within the UpdatePanel, I want to refresh the tree. This just does not seem to be possible.

AJAX :: Wrapping Controls In UpdatePanel?

May 17, 2010

I have a page that is essentially a group of controls on top, a button in the middle and a DataGrid at the bottom.

I wanted some asynchronous code to get ran; so I wrapped the bottom DataGrid in an UpdatePanel and made the button in the middle as the async trigger. This is working great. However, the button also needs to clear out the values of the controls up top after it adds to the bottom DataGrid.

The code to clear these controls out gets ran, but nothing changes on screen. I assume this is because the top controls need to be wrapped in an UpdatePanel as well. I did this, but I'm having a problem.

One of the controls up top is an asp:ImageButton. Clicking on this button executes a handler for the click event in the VB code behind. This VB constructs a Javascript snippet that opens a new window with a different page (don't ask me why it is done this way). That VB code gets executed, but nothing happens.

AJAX :: Updating Controls Inside UpdatePanel?

May 10, 2010

I have a couple of dropdowns inside an Ajax Update Panel. When I try to rebind the controls or set the selected index of the drodowns inside the panel, they don't respond.

For example, I update the database records and need the dropdowns to display updated data. I set the data source for the dropdowns, rebind them and update the UpdatePanel, but it still shows the old data.

AJAX :: UpdatePanel: Controls Inside Are Now Inaccessible?

Aug 25, 2010

I had a group of controls. They were programmatically referenced so that I could change the text of the labels. It all worked well. So I just put an update panel in and put the controls [i]inside[/i] the UpdatePanel. Now the code that references these labels inside the update panel are no longer recognized. I imagine it's because they are inside the updatepanel now. But for some reason, the web application still works correctly, but the code is blotched up with errors every time a label inside the updatepanel is referenced. My question is, how do I programmatically reference the labels that are located inside the update panel?

AJAX :: Dynamically Adding Controls To A Page With An Updatepanel?

Nov 14, 2010

I am dynamically adding controls to a page with an updatepanel. The controls do trigger a post back but their events do not fire.

For example:

LinkButton link =
new
LinkButton();
link.Height = 45;
link.Width = 250;
link.Font.Underline =
link.Font.Bold =
link.ValidationGroup = "NoValidation";
link.Click += new
EventHandler(EventDoesNotFire);

I have set a break point on the Load_Page and in the EventDoesNotFire method. The Load_Page fires, but it never enters the EverDoesNotFire method.

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.

Web Forms :: Hooking Dynamic Controls Inside An Updatepanel As An Asynctrigger To Another UpdatePanel?

Oct 7, 2010

I have two update panels and one javascript control.

When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.

However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.
