what im tryign to do is, onclick of a hyperlink, update a list box inside an update panel

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 have two nested UpdatePanle and a button and an editor in parent panel and a GridView in child panel.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Button ID="btn_UsersList" runat="server" onclick="btn_UsersList_Click"
Text="users" />
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView_UsersList" runat="server">
</asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btn_UsersList" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
<FCKeditorV2:FCKeditor ID="FCKeditor_Message" runat="server"
BasePath="~/fckeditor/"></FCKeditorV2:FCKeditor>
</ContentTemplate>
</asp:UpdatePanel>
I'd like to update the child panel when click button but don't update the parent UpdatePanel.
I have a simple ListBox and a Ajax File Upload control. I have these controls within an Update panel. But I cannot get the ListBox to update upon uploading a new file.

I am adding a click event (display alert on click) to a html hyperlink inside an UpdatePanel on document(ready). However, the event never gets fired when I click the hyperlink. Is it because of ASync postback? What is the correct way to do this?

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I have a databound listbox that is inside an update panel. When selecting an item in the listbox, I want it to populate labels in a panel that are displayed in a modalpopup. When I click on the listbox, I can see that the data is passed to the labels and the modal.Show() is executed by stepping through the code. However, the modalpopup comes up but with no data.

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've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I am having a weird issue with the update panels. I have an update panel in UpdateMode = Conditional . I have a dropdown list and a grid view..the gridview has to be updated ÖnSelectionChanged event on the dropdown.
The issue here is on changing the selection on dropdown, the onselectionchanged event is triggered, new data is grabbed, bound to gridview..but does nt update the update panel even after the updatepanel.update();

I have country dropdown, now on change of its index i need to populate items in listbox (not in the dropdown).
View 1 Replies 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?

I have a formview in Edit Mode, within an update Panel all and these arewithin a Modal Pop Up extender.On clicking Formview Update button, I want an image to appear within the pop up.I have put the image within another panel1 and runat server.For some reason the image is not showing on clicking update button.
View 13 RepliesI am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged
End Sub
Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged
End Sub
Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click
Dim SwapValue As String = "Sixty Pounds"
Dim Counter As Integer = 8
Dim SwapN0 As Integer
lstSwapList.Items.Add(SwapValue)
lstSwapList.Items.Add(Counter)
lstSwapList.Items.Add(New ListItem("300", "1"))
lstSwapList.Items.Add(New ListItem("ASP.Net", "2"))
lstSwapList.Items.Add(New ListItem("Programming", "3"))
SwapN0 = lstSwapList.SelectedValue
For Counter = 0 To -1
SwapN0 = lstContent.Items.Count
Next
End Sub
Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click
lstSwapList.Items.Remove(lstSwapList.SelectedValue)
End Sub
Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click
End Sub
End Class

i have a religion dropdown1 , on this selectedindexchange i have to populate castes into the listbox(not dropdownlist).
i am unable to use cascadingdropdown as it is tightly binded with dropdowns.
please guide me how do i update listbox items based on the dropdown selected value using ajax.
i tried with pagemethods getting the dictionary object using JS function and thought of binding it.
but i am unable to bind the list.
//html code
Religion
<asp:DropDownList ID="ddlReligion_RS" runat="server" TabIndex="6" onchange="GetCastes_RS(this.value);">
</asp:DropDownList>
<br />
Caste
<asp:ListBox SelectionMode="Multiple" ID="lstBxCst_RS" runat="server">
</asp:ListBox>
//js function
function GetCastes_RS(relgnID)
{
abc.BLL.Services.AjaxService.GetCastes(relgnID,
function (resp)
{
var ddlCaste= document.getElementById("<%=lstBxCaste_RS.ClientID%>");
ddlCaste.length=0;
var castesList = resp;
alert (resp);
if(castesList.keys.length >0)
{
for(var i=0 ;i< castesList.keys.length;i++)
{
op=castesList.keys[i];
ddlCaste.options[ddlCaste.length]=new Option(castesList.values[i],op);
}
}
},
function(val)
{
alert(val.get_message());
}
);
}
i could call the webmethod, but i am getting this error in javascript.

trying to display the div (in updatepanel) while button 'btnDisplay' is clicked. And disappear when clicked second time.

looking for the proper onclick event code.
I got a little problem that is... well... quite frustrating. I have dynamically created a button, outside the UpdatePanel, just like that:

This is working... no problem with that... The problem is this button, that I add into an UpdatePanel:

I just can't catch the click event of the button.
I have a asp:ListBox wrapped inside an asp:UpdatePanel. The list box contains Bus Codes. If I select AH, for example, and then scroll down to select XY, the listbox jumps back up to the top of the list instead of staying on XY. Listbox's autopost back is set to True. As I need to get selected values and then pass it to another web page to display a crystal report. The report web page is opened using JavaScript Window.Open and on page load of the web page that contains the listbox this JavaScript is added to a button. Is there a way I can stop my list box jumping back to the 1st item?
View 13 RepliesI have an UpdatePanel with a MultiView inside. I am using jQuery to call the server to run some logic and based on it, change the view in the MultiView. The problem is that the updatepanel is not getting refreshed.
My UpdatePanel:
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
This is my call to the server:
[code]....
When the page loads again, the multiview is not showing the assigned view.
I have noticed that the call to the server doesn't set Page.IsPostback = true, it remains false. Perhaps this is somehow related?
I am dynamically ading the following to an UpdatePanel
Tab control which has X# of Tabs, each Tab has a various labels and a Rating Control.
When the user hits the Rating contro, the RATING_Changed fires and runs a stored Proc to update the DB. I want the Panel to then display the newest information back from the DB. I can't seem to get the last part to work. I'm still learning .NET so i may have missed somethign easy, but i've tried setting AutoPopstback, using Triggers, etc.
The DB Update does take place but the NEW contents are not displayed

View 2 RepliesI am using an updatepanel. Inside this updatepanel I have a LinkButton with the clickevent below.
When clicking this button the Image does not update to a new image. As seen I am assigning the Session variable a new Image path(Session["showThisImage"]) which I am getting in the Page_Load event.
Now I am putting this path in a public variable that is set to the HTML control "Img1" with help of Page.DataBind().
However the Image does not change which is the problem, the image is still there. But other things as labels, links etc do get updated with new data which I haven´t put in this example which means that the updatepanel works except changing the Image here? Also to mention is that if you uncomment: "Response.Redirect("ThisPage.aspx");" the image will change but this will mean a FULL postback which I dont want.
