I've got a TextBox with AutoPostBack="true" and OnTextChanged property set.
The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.
Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.
Here's how the thing looks:
[Code]....
Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel. So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed. But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.
I have an updatepanel on my master page that just updates the database every 30 seconds, what is happening is that everytime it is fired, it will refresh everything on the page_load of the content page that are not under ispostback = false. to disable such a thing just for this specific updatepanel?
VS 2008Update PanelIn the update panel, is a gridview, and an asp:panel that contains some other controls, including the button I want to trigger the update of the gridviewThe gridview is tied to a sqldatasource, although I have tried multiple methods to get the data and all failed
Here is the problem:
User logs in and fills out the top part of the form. That submits some data to a table, returns the ID of the row submitted and makes an asp:panel visible (panel.visible=true). This update panel exists inside of the UpdatePanel. The user clicks a drop down list and selects a name. When this happens, another panel becomes visible, using the same process, to allow the user to enter data about the name they selected. So far, everything works.
What Should Happen next:
User clicks "Add" buttonDatabase is updated with the data enteredDatasource refreshesGridview refreshes - It is not visible at load because there are no records for it to show.
What Actually Happens:
User clicks "Add" button Database is updated with the data entered - This has been verified Datasource should update, but not sure it is Gridview does not show.
I have an UpdatePanel with some controls, and a tree control outside of the UpdatePanel. The tree control is huge (~4 MB) hence I don't want to refresh the tree on postbacks from within the UpdatePanel.
Main settings:

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.
I have a page that displays data depending upon the date range entered by the user into two textboxes. I have added the CalendarExtender control from the Ajax Toolbox to each of these two textboxes, and I would like the associated updatePanel to refresh with new data whenever either of the two dates is changed. Sounds simple enough, but I have not been able to manage it so far.
This GridView contains a TemplateField with a LinkButton that displays a text value. When the link button is clicked, the code behind needs to capture the text value of the button, and then refresh the GridView with an asynchronous postback within the UpdatePanel and display the updated output.
The post-back event is occurring, and I'm able to capture the event in Visual Studio 2010 debugger. But, the screen contents do not change after this event occurs. No exception gets thrown, at least from what I can see in debugger.
Portions of the sanitized code appear below. The GridView actually appears on a page that contains 2 dropdown lists and 2 other GridViews. There is just one UpdatePanel on this page.

This is in the Code-Behind.

I can put a break point in the above method, and it is captured when the lnkHostName button is clicked. Stepping through the lnkHostName_Click() method, the ReloadPage() method successfully runs, then executes this method:
[Code]....
This runs successfully, and the DataSet which gets returned contains 1 row of data rather than several rows. This is what I expect to happen. Once the filter is selected in my test case just 1 row should get returned. The problem is that I don't see that output refreshed on the screen. The grdProcesses gridview continues to display the original dataset of several rows, rather than just one row of data. To additionally test this, I tried setting the visibility of grdProcesses to false within this method when the HostName had a value. Again, this ran without an error, but the GridView was still visible. And I also tested by updating the contents of a label with the HostName value. The new value was never displayed in the label. I also tried putting the lnkHostName button into the triggers, ala:
[Code]....
But the following exception gets thrown when that button is added, "A control with ID 'lnkHostName' could not be found for the trigger in UpdatePanel 'upMain'."
What's frustrating is that everything appears to run smoothly in debugger. But in reality the expected output never gets refreshed on the screen. Perhaps I need to use an alternate trigger in the AsyncPostBackTrigger. I'm open to using a command button or some other artifact.
I have a requirement where a user logs on to a server where exists a website. The user bring up the site on a browser on that server and loads a power point presentation slide. At that time, users using their laptop clicks on the link to that site and sees that particular PPT slide loaded on the server. Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.
I have a dropDownList on a page that I need to refresh with new database entries whenever new content is added to my DB.Basically, I have a list of usernames in one dropdown, and when I add a new username to the database I want this to be reflected in the dropdown without refreshing the whole page i.e. on the fly.I have used update panel but partial postback is occuring but i want page should not refreshing at allI hope someone can help, I have looked around and not found any solutions.
I am very new to ASP, .NET and MVC but am reasonable with HTML, Javascript and CSS. I was hoping someone could answer a question about how to change a page without refreshing the actual page.
The dashboard div contains a lot of information that will be present on each page, so when the user navigates to another page, I only want the MainContent to change. I suppose this could be done by using an iframe, but I'd rather not go that path.
How would I go about this? Are there any tutorials that cover this? What functions/terms should I be looking for regarding this?
Edit: I don't know if it is relevant, but I thought I'd better state that I am trying to do this using MVC, and I want to get the content of the MainContent div handled by the appropriate controller of the 'page' contained within that div.
All i have issue we are implementing a web control . in this web control we have use multiple UI controls just like textbox,dropdown, etc... Allmost this page have more than 100 controls, these are dynamically created.But When this page is render on ie7 . this page is not load and refresh again and again.
I'm using MS AJAX's accordion control. It works fine normally, but I can't seem to get it to work with an UpdatePanel. My layout is like this:
<div id="accordion"> <div><a href="#">Header1</a></div> <div class="acc_content"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" > <ContentTemplate> <asp:button id="btnToggle" runat="server" text="toggle"/> //my repeater contents go here. The buttons within the repeater cause a postback, but changes cannot be seen unless the page is manually refreshed (since the updatepanel doesn't refresh) </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnToggle" EventName="click" /> <asp:AsyncPostBackTrigger ControlID="btnAdd" EventName="click" /> //this button is outside the updatepanel </ContentTemplate> </Triggers> </asp:UpdatePanel> </div> <div><a href="#">Header 2 </a></div> <div class="acc_content"> Content of the second pane </div> </div>
There are postbacks occurring when I click the buttons, but the updatepanel never refreshes or updated. I tried adding UpdatePanel1.Update() in the code-behind for each postback event, but no luck. Any ideas as to why this is happening?
I have been reading a lot about UpdateMode set to Conditional on multiple UpdatePanels on a page. It seems that when set to Conditional only the UpdatePanel affected by the event will refresh. It is not happening on my case and I don't know what am I doing wrong.
This is the scenario. I have 4 updatePanel all set to Conditional. I have external buttons that will call the Update method per each panel but the whole page refreshes when I click on any of the buttons.
I have an Infragistics ultrawebgrid inside an asp:UpdatePanel control.The issue is each time the page is refreshed, the grid becomes invisible.But,the data is bound to the grid during postback also.
I have used master pages inside application and menu is placed on master oage.On click of that menu content pages are called,i want to update only content page But the whole page is being refreshed.I have also used the Update panels on content.

there is a textbox and button control. On button click event content of textbox is submitted to database and javascript alert is displayed. Now the problem is- If I am refreshing the page using F5 then same value of textbox is being submitted into database and javascript alert is coming again.
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
