AJAX :: Dropdownlist.onselectindexchanged Only Refresh Some Portions Data, Not The Whole Page?
Mar 25, 2010
I have the webpage with below code. There exists dropdownlist within the gridview and updatepanel. I hope that the dropdownlistddlAltProduct refresh only some portion of data in div when OnSelectedIndexChanged. Not the whole page as now as you see autopostback='true'. How to change the current situations???
I have a web form that contains a dropdownlist which shows list of cities in it. I have an add button on click of which I am opening a Popup window to open a new page that contains a text box where in i am entering new city name and submit button.
I want that after click submit button the window should be closed and on the parent page the dropdownlist gets refreshed with the new value. I am able to do it but the whole page gets postbacked which I do not want. I have added the dropdownlist in the update panel but not able to do the partial postback.
I have a number of cascading dropdownlist controls on a page. The results in dropdownlist2 are dependent on the results in dropdownlist1, pretty basic stuff.
I now would like to eliminate the terrible postback or refresh of the page that occurs after the SelectedIndexChanged event fires on dropdownlist1, is it possible to do that in Ajax?
What I want the results in dropdownlist2 to populate without the obvious refresh of the page.
i my futur webpage i wan't to use ajax. First i tough to use a panel to hold my controls and turn in visible/invisible with buttons. But if i use ajax and i refresh the page and show other controls.
I have a page with 3 different kind of data. in the first you can't type a name, you function, ... in the other more specific and the last one an evaluation. but if i refresh my page to a other what hapends with the data i typed in the first, can it be saved at temporary place. Because at the end all the data will be saved in a SQL database, but it still needs to be possible before it goes into the database to change it.
This is updatepanel code. as shown in the code, i am referring to ddlClass in triggers which already calls a javascript function loadAllDefaults();
The problem is, since ddlClass is calling javascript function 'onchange' property, i cannot call any other function of backend code and I want to refresh the updatepanel on the basis of selected value of dropdownlist.
How can i do this? I have created a function in c# code in backend but I am not able to call both functions together!
I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt
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 40 record in database. But I am displaying 10 record in each page in store grid. But the problem is when I refresh the page or grid, it shows first record in first page. how can I get current page data when refreshing data? How can I avoid this
I have a CreateUserWizard control, for which I customized the first step.
All I did was add 3 DropdownLists to represent Date of Birth fields. So I have Month, Day, and Year dropdowns.
I have ViewState disabled at application level (disabled it in web.config).
I enabled viewstate on Month, enabled AutoPostback = true, and have a method for the event OnSelectedIndexChanged.
Depending on the Month, the values in Day can range from 28-31.
Now when I fill out the form and hit Create User, the Month_OnSelectedIndexChanged event gets fired first for some reason. I found this out by debugging. Because of this, it does not save the Day the user has picked.
I've built a page which has an update form, and above that, a photo (based on the same edit). The photo is loaded based on the selected table row being edited.
On this page, I've got a button that opens a modal in an iFrame and allows the user to update just their profile image (all works fine). But when the modal is closed, I'd like to reload JUST the photo (and not the entire page), as it will have changed.
How should I go about doing this? I assume I'll need to use some Ajax controls?
I am creating a report and I have several paragraphs of text making up my document inside those paragraphs I have data from my database so its made up of static and data driven fields. I need to bold and under line some of my fields inside my expression. I tried creating several columns and putting in my fields in other columns and that does work however it doesn't look that great sometimes there are large gaps in my text between the static and the dynamic.
here is an example of one of about 14 paragrahs in my report.
="The Borrower hereby notifies MACED that it will use "& FormatCurrency(Fields!TotalAmount.Value) & " to fund the costs reflected in this Requisition No. " & Fields!pk_ReqID.Value & ". The above described loan proceeds will be used for the following purposes and in the following amounts:"
As you can see thats one large field I have it works great other than I need to bold and underline my Value and my date can this be done inside my expression in some way like FormatCurrency(Fields!TotalAmount.Value,"BOLD")
I have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).
Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.
Here's the code:

On Selected Index Change code for each
For the First:
[Code]....
For the Second:
Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel") Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg") If ddlModel.SelectedValue = "Add" Then 'Add New Record txtDDLName.Value = "ddlModel" txtDtlsViewName.Value = "dtlBikes" txtItemType.Value = "BikeModel" txtParentID.Value = ddlMfg.SelectedValue txtNewItem.Text = "" txtNewItem.Focus() lblNewItem.Text = "Enter New Model:" modInsertItem.Show() End If End Sub
I have a gridView and on the DataBound event I am assigning a Session variable from one of the gridview results. This session is then used to determine if certain nodes in a menu are visible. One problem is that when the session variable is assigned, the menu is not updating, until either I refresh the page manully in the browser or move to another page.
In this repeater linkbuttons are generetaed with an onclick event.This onclick event sets a multiview to the corresponding view.The multiview is in an update panel as well.When a linkbutton in the repeater is clicked the corresponding view is shown, but a complete refresh of the page is done.How can this be prevented, because when I have just linkbuttons on the page (so not in a repeater) that set the multiview to the corresponding view, only the multiview is refreshed instead of the complete page
I have a user control that is not visible on the page when the page is first loaded. I have a textbox and on the textchanged event I'm making the control visible, however the control does not reload. Is there a way to refresh the control?

i have a website that has html tables <tr></tr> tags. I have problems with refreshing my page. When the select a radiobutton of a list, there should apear a other control. But that only happens when i refresh the page my clicking on a button. So i thought of using ajax.
I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.
Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.

I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded.
How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)
