AJAX :: How Another Updatepanel Can Be Refreshed Everytime When A Particular Updatepanel Is Refreshed
Aug 13, 2010
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 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 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 got strange behaviour here. My environment is VS.Net 2008 Team server and I tried to use updatepanel but failed.
When I clicked the button, I expect Label3 inside updatepanel to be updated and Label2 remained the same, AND of course without page refreshing flick. But the result is page is completed refreshed and both labels are updeted.
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 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?
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 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?
I am running the code below to read a sql table and populate the values into a list. This works on the first run through, but after the data has been processed, and the process then re runs, if the sql table has been modified externally, the read of the records does not change. I imagine it is being cached somwhere but as I re dim the dData variable, shouldn't it all be dropped and run afresh?
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.

I have an ASP.Net 3.5 application with a menu. The menu is set to an xmlDataSource. The xmlDataSource is given the menus for the user as a dataset. The xmlDataSource uses an xsl transform file.Here is the code behind:
My problem is, when another user logs into the system, he/she gets the previous user's menus. This is based on time somehow, because if you wait long enough after another user has left a page, you'll get the proper menus.Could it have something to do with page caching? Is there something I'm missing with menus?
