AJAX :: UpdatePanel Causes The Whole Page Refreshed?
Mar 1, 2011
I have an asp UpdatePanel, an asp panel, an asp timer, and an asp label on my web page, as you know the whole idea of updatepanel is trying to implementing partial page rendering mechanisem, however, it is not the case in my scenario, here is the code:
and on the pageload event, i assign:
strangely, the labl1 does update the time without causing the whole page post back, but the panel does cause the whole page refreshed, and the asp panel contains asp buttons and those buttons are generated dynamically by code behand c# file, am i missing sth here or the nature of asp:panel will cause the whole page post back?
I am using two Updatepanels in ASP.NET AJAX and as soon as there is some event in first updatepanel, it will get refreshed at that time I want my second Updatepanel getting refreshed too. How can I do that ?
I'm writing a small photo album application and having some problem of refreshing the original images in the updatepanel. I have two updatepanels, one on the left contains a gridview to display image thumbs, and the other in the right contains an image control. When click on the thumb on the left, the file name of the image on the right will be inserted using the CommandArgument value. However, when I clicked the thumb, nothing happened. Instead of refreshing an image, I put a label and it worked fine. The following is my aspx side code and code behind.
I have an extra asp.net label to show success or error message after the add, update or delete a row, but using the BlockUI, I am unable to do it, cause the label is somehow not refresh even if i put it under the BlockUI.
I have a web application project, in which i have 2 projects one is for my UI and other for dealing with database. In UI i have a page on which i have used update panel and script manager, the usual procedure, but surprisingly update panel is not working my page is getting refreshed.
I have tweaked some button colors on a webform after updating those pages on server where iis is.From my local machine i can see the updated colors of button.But in some of the other users machines they still see the old webform.even though they refresh there IE.but when they use firefox they can see the new changes.What is wrong with IE, even after deleting cache still it is showing old webform.
MyMasterPage.aspx and content page MyDefault.aspx. MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into TextBox1Default1 at content page MyDefault.aspx, and then refresh UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.
My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008
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?
I have a Reportviewer control linked to Report1.rdlc with a matrix with Drillthrough activiated.When I click the "+" buttons to drill through, even I enclosed the control with Penal etc it still caused the whole page refreshed which is annoying. The same Panel code works well on other ASP.net controls on page on running.
I am using Standard control FileUpload asp.net to upload a simple file to server. When I select a file and submit, the page is refreshed to the file is uploaded to server. Then I using a UpdatePanel to perevent the refresh. But in this way the file is not uploaded and FileUploaded.HasFile property return false. What can I do?
I have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.
After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
I have an asp.net ajax enabled form that looks like this:
As you can see in the OnPreRender event, the Save button gets enabled or disabled depending on whether the datagrid is in edit mode or not. When I step in the code, it operates correctly in the code, but it does not get reflected correctly on the screen. That is, even when btnSave.Enabled set to true in the code, the browser displays the disabled button. Any idea why this might be happening?
yes i know half post ack occurs but it does occur right?so why doesnt the dropdownlist get refreshed when the timer ticks on?. for alternative i tried manually clicking a button to create postback but still no refresh of connection of th list
