Im trying to write a page that lets the user update their details and then will change the page on postback to reflect the new details they have entered into the form. For some reason its not working. I have used a Page_PreRender method and it is not getting the newly saved value from the database. It seems to be getting the value that was saved on the previous postback. Here is the code:

When an asynchronous postback happened inside update panel, another postback happens also for MasterPage not only update panel embedded page .
I want to prevent this MasterPage postback .

and another page which is test.aspx which is content page of MasterPage
i have update panel at test.aspx
when asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Load
i want to prevent this (it should not also load MasterPage Page_Load)

I've got a page that posts back constantly and if im on the inputbox thats instide the update panel i loose focus on postback
how would i get it to recognise that im on the textbox in the update panel and keep focus on it.
It works fine in Firefox but in IE 7 fails doing the postback sometimes. Is it just a problem with my browser? The partial postback inside the update panel works great in both browsers, but when I hit the button outside the panel, the complete postback doesn;t work in IE....

I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

I have a link button inside an update panel. The problem is the link button on postback is updating the whole page. Tried it with a normal button and the page is not refreshed all. Here's the code.
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
From one of my webpage, I am opening up another form as ModalDialog, and on this form, I have a Grid, Treeview and some other controls.
[Code]....
I have some code on click of Treeview Node, I fill out other data in Grid on click of Treeview Node.
Now the problem is when page posts back ( on click of Treeview Node ) , page flickers once during filling up data in Grid.
Basically whenever page.ispostback is true, page flickers, Now I want to avoid this.
I have to keep "SmartNavigation="false"" on this page because of some of the Treeview Problems.
Specifically on Node click of Treeview and on Update button press.
I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.
The update panel looks like this:
[code]....
So far, I have tried adding an async postback trigger for the user control, which does cause an async postback but does not update the rest of the text in the update panel. In otherwords, the async postback occurs and the next page shows up, but the original text in the repeater is there as well just below it.
I have also confirmed that I have IDS set on my linkbuttons, since that can trigger a full postback inside an update panel.
I have tried changing the update panel mode (Always, Conditional, ChildrenAsTriggers, etc.).
None of it makes a difference - the only thing that actually causes an async postback is to use the trigger, but then the rest of the content in the update panel is not updated, so I get duplicate content.

How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page
Custom Control
UpdatePanel
LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)
Is something like this possible?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
I am new to the concept and feel like there must be something really easy that I am missing.
when postback occurs due to update panel's child control then in page load event how can i know that it was dut to update panel ?i.e., i want to differentiate between general postback and postback due to update panel's child control in page load event .How is that possible ?

View 4 RepliesI have a details view that contains a dropdown list
40%
50%
70%
80%
100%
and would like to update the percentage value in the access data table - no problemHowever I would like to also update another field "Saledate" with the current date/time if 100% is selected and if it is subsequently amended from 100% back to any of the others then the field is set to null.I initially though that i could have an update gridview within the detailsview editItemtemplate as per the code below but this fires before the postback on update and therefore would be grateful if someone could let me know how to write the code that will fire on the onupdated event

I am checking to see on the form if they answer No to question one then go to comments. On the client side I added autopostback="true". So when the page reloads the random number in the label is updating to a new number. How can I avoid the random number not to be updated when the page post pack to itself?
Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load
Dtetxt.Text = Date.Now
F()
End Sub
Private Sub F()
Dim _r As New Random()
Dim n As Integer = _r.[Next](5)
' Can return 0, 1, 2, 3, or 4
Label2.Text = n.ToString

I have a GridView on a web form, which displays data fetch from database using Linq. When I update the GridView in a button event on server side everything works fine. Now I want to update the GridView from a JavaScript funciton call. Here is the code on the page.
[Code]....
And here is the code behide
protected void Buttons_Click(object sender, EventArgs e)
[Code]....
The problem is that GridView1 never gets updated in IE. It works perfectly in Firefox. I can see the event was triggered by the Javascirpt call and I get correct dataset from database through debug. However the GridView never display the correct data. Is GridView handled different from regular web form control?
I have Gridview that opens in the Edit Template with UPDATE and CANCEL links at the bottom, so the users can modify records.
When the user clicks UPDATE there is no indication that the DB was updated. I don't want to redirect the user.
What is the easiest way to provide a confirmation that the DB was updated?
richtext not wroking in update panel.
View 1 RepliesI have multiple gridviews on one page that connect to the db with different sql datasources.
They each show records with differents "status's"(this is a column in my table). When you update the status on one record I'd like it to display straight away in the other gridview. At the moment I have to reload the page after the update in order to see the changes. Can I set the update buttons in the gridviews to postback after updating?
I removed the Trigger section the partial post back does not occur when I click add button on footertemplate of the gridview.
View 1 RepliesI have a GridView within an UpdatePanel - <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true">
Without listing any Triggers, I get a full postback when I visit a particular row within the GridView and click the 'Edit' button for that row.
However, if I enter the following trigger...
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
