I'm not doing anything in the tick, just letting it call the Load event for the Update Panel. Whenever the Timer ticks though, if I am typing in another area of the page I stop being able to type, and lose the cursor, and I have to click around to get it back, so it makes the page pretty unusable.
i have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.
i hv a gridview in modal popup,I hv taken checkboxes in itemtemplate and written code in javascript function to checked or uncheck the checkboxes.and in pageindexchanged event calling that javascript function to maintain the state of checkboxes.it is working fine.but when i put it inside update panel nothing is happening.
Looking for the best technique on handling or at least some documentation showing an example.
Starting Page
Gridview control withing an update panel (also various controls used for filtering NOT IN UPDATE PANEL)
Databinding does not happen during page load.
Databinding is initiated when update panel trigger (asp:Button object) is clicked
Hyperlink column is added to returned records
Hyperlink posts to a separate page for detail for record which the hyperlink was clicked.
Second Page
While navigating via the browser back button to previous page (which contained the update panel and gridview) only the (various controls used for filtering) have retained state. The gridview is not shown (which is how the page loads initially when starting) How can I retain the state of the Gridview and add a step in the browser history all together?
I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
Now i was trying to use an UPDATE PANEL, in order to when i click button Save, only the DIV updates. Because the whole DIV is closing when i click on SAVE, even if i put a div in an update panel.
I have a form, with an update panel and the EnablePartialRendering set to true on the page. Here's my problem, the page size with every AsyncPostBack gets larger, even if my code makes no changes to the markup. It also, never stops... it just keeps growing about 3-4K with every AsyncPostBack. If EnablePartialRendering is set to false, full postbacks do not cause the page size to grow like that. It's like it's sending resources and then never getting rid of them out of the page even though they're not being used because an updated copy has come down.
1.) Is it supposed to work like that?
2.) If it's not, what can I do to not have 4K added to the page size everytime an AsyncPostBack occurs (not again, full PostBacks do not have that same behavior).
3.) This behavior happens whether I compress the ViewState or not (I am using ViewState compression). However, the ViewState size is NOT growing... it's the size of the content in the page that is (I'm monitoring the ViewState size/the Page Size closely).
I have one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
I am using update panel in my ASP.net page for partial page postbacks. I have gridview and a button "Export" which on click will call the Export method from the below class. If I remove the update Panel everything will work as expected. But if there is a update panel it will not work and throws this error.
Below is the code for the
using System; using System.Data; using System.Configuration; using System.IO; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls;
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:
[Code]....
Does anyone know the solution to this issue or if Gridviews just don't refresh in UpdatePanels.
I've an ASP.NET page with UpdatePanel containing WebPartManager, two web part zones and user controls as web parts. The web parts have GridViews. When testing on LCD screens, sometime GridView does not update correctly - some information is missing from columns in some rows. On normal PC the rendering is just fine. What might be the problem ? I'm using PageMethods to check for page update and then use _doPostback to update the whole page. Sometimes the caption of the web parts have also overlapped letters.
I've UpdateMode as conditional with rendering as block. Should I use inline mode ? What other things I could check and try ? Should I follow this link [URL] to destroy the GridView inside the web part on partial rendering?
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 selected index changed event. I've been trying to figure this out for a month now. Oh ya, this form is within a master page.
Here's the gridview code:
[Code]....
And this is the event that handles the delete command:
I have an UpdateprogressControl on my page and an Update panel. The UpdateProgress is not associated with the UpdatePanel as I want the update progress to show when the user clicks on any control in or outside the Updatepanel content. However the update progress only shows when a control is fired from within the update panel and not on any control outside the update panel.
I have used the update panel for avoiding reload page.but because of update pane radiobutton event not fired properly. I want to show Popup widow on link click.This popup contain the gridview.When I choose radiobutton which belogs to that gridview popup will be closed and as per grid row selection data will be display in text box which are belogs to form rather then popup.Now because of update panel I can avoid reloading page but above functionality doesnot work.
I have to update a gridview inside an updatepanel in a button click.The thing is i'm having gridview in contentpage.I have placed scriptmanager in masterpage.when i clicked on the button to trigger the updatepanel,no update is happening in gridview.Moreover,after placing updatepanel control in contentpage,i saw a redcurvedline (which is an error basically) below the updatepanel control's text which is showing an error as "Element 'updatepanel' is not known element.This can occur if there is a compilation error in the website" in .aspx page's source view.I have attached the screen shot here of that page here for your reference.
when I click on a record in gridview it should call the SelectedIndexChanged event and do some operations.
SelectedIndexChanged event is working OK, but when I put the gridview inside ajax updatepanle SelectedIndexChanged event will not response even if I add AsyncPostBackTrigger trigger for SelectedIndexChanged event.
I have a gridview in an update panel with the following code to select a row, this in turn updates another updatepanel with details from the form record.
protected void gvMainGrid_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { //Make the entire row clickable to select this record //Uses javascript to post page back e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline';"; e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';"; e.Row.Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(this.gvMainGrid, "Select$" + e.Row.RowIndex)); } }
I am manually binding the gridview from a database and don't want to rebind the grid just to highlight the row, but I can't seem to add any javascript to the onclick event, it seems to either show the GetPostBackClientHyperlink or the row highlight javascript.
