Gridview's in Update Panel not updating

I have 2 gridviews in an update panel that for some reason will not update.  There is no data entry, paging, sorting going on, the data is just there to be displayed.  I'm using a timer that initiates every 5 minutes to trigger the updatepanel.  I also have an updatepanel on an additional page where I am also using a trigger to fire the updatepanel with 2 charts and 1 oneline/column gridview.  The 2 charts update just like they are supposed to however the gridview does not. Here is the code for the 2 Gridview aspx page:</head> <body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:Timer ID="Timer1" runat="server" Interval="300000" Enabled="True"> </asp:Timer> <br /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" /> </Triggers> <ContentTemplate> <table class="style1"> <tr>

How to refresh only single update panel



I for a page with multiple update panel in parent page, I got a button that will open a child window, after I close the child window, how can I refresh the parent page? And I only want to refresh a single update panel section instead of all other update panel section.


page inside update panel doesn't refresh the session object after postback of any control



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)

Any help is greatly appreciated.

Thanks in advance

Ajax update panel refresh and dropdown behaviour in firefox


I have found an odd bug in my application.  I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.

Now the strange behaviour in firefox and not IE:

If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.

Anybody had the same problem or does anyone have a fix out there?

Your help would be appreciated.





Update panel problem in gridview footer


On my aspx page, I'm having troubles when I have an update panel within the footer template of a gridview. It appears to be an intermitent problem that occurs on subsequent postback when you do a delete command in the gridview. The first delete command always goes through fine (first postback). Clicking on another row to delete on the gridview (or any other button on the form) triggers this error:

An error has occurred because a control with id 'ctl00$SupremeContent$grdLineNumbers$ctl09$ctl00' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

If you click the back button in the browser, then click on another page, then come back to this page, you can delete another record. Another attempt to delete another record brings you back to the above problem. Thectl00$SupremeContent$grdLineNumbers$ctl09$ctl00 changes each time you delete, come back to the page and delete.

If I disable the udpate panel, there's no errors.

The reason I have the update panel is so that the user can select the relevant pipe specification (they see multiple columns using a textbox, drop down extender, panel and gridview) without the form's data being reset by the embedded gridview's

refresh update panel content with new css styles


Ok, I was working on this last week and took a break from it to 'regroup' and start over.


Here is what I'm trying to accomplish.

1. have  a web form with dropdowns to allow the user to select font sizes, colors, background image, etc.

2. I want to the form to be updated with the new styles in an update panel.

3. Once the user clicks the apply button, I want the updatepanel to refresh with the new styles.


I tried this by creating an css on the fly, but the updatepanel wasn't picking up the new css without doing a full page refresh, (which we don't want to do).

I only want the updatepanel refresh and either use inline styles, a <style> on the web form etc,

any suggestions or recommendations on how to accomplish something like this?

update the Oracle time stamp and userid when using Gridview



  I am using Gridview against Oracle 9i and I am using the GridView update function to update table fields when someone edits a row.  I have captured the userid and the date/time when someone peforms this function but I have yet to figure out how to get it into the GridView row so that when the update button is pushed, the current date and time and the user's userid it displayed in the row of the table.  I've tried many different things but am at a loss to nail down the code for this.  Below is a piece of the code I am working with.

Editing the Data in a GridView

In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

How to format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.
