my code is very simple. I have one updatepanel, it has one lable and one dropdownlist. everytime, dropdownlist index changed. Label shows selected value. if you select any options besides the first one, it works. if you go back to the first option, then event will not get fired. spending hrs searching on google, couldn't find anything useful.
here's my code

Now i am having two dropdown one is asp dropdownlist and 2ND is MultiSelect-DropDownList-with-CheckBoxes. 2nd dropdown is populating on selected value of first.On page load it works fine. Now, on change of value in dropdown, selected index change 2nd dropdown (MultiSelect-DropDownList-with-CheckBoxes) fills but i see a list box instead of dropdown.
I have a page with an UpdatePanel wich inside has a dropdownlist control. Everything on the page is created dynamically on Page_Init.
DropDownList items are taken from the database with a Select based on some table.
I want to click a button inside the drop down list that inserts a new row in the table that dropdownlist control is based on, and then, on another postback I want the item to appear in the dropdownlist and select it.
On the first button click I insert my row. Ok. On the second button click (I just want to do a postback), in Page_Init I check that the dropdownlist control contains the item I have inserted, and it is there. But in Page_Load event of the same postback I want to set the value selected to be the new value,
but now the drop down list doesn't contain the item anymore!.
firstly,i am going nuts with this problem. here it is:
i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.
now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to
see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.
i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage

I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.
ScriptManager in the masterpage:

In my application, I am using different user control for different tasks. I used an update panel to load user controls with ajax. It is working fine. I am using some other update panels inside the user controls. My problem is, the inner update panel(UpdatePanel placed inside the user control) is not working properly.
View 1 Repliesi have a gridview in updatepanel in this case:
[Code]....
I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.
I am building a website using ASP.net ajax. there are 3 <asp:panel> controls in the page and each contains a number of dynamic linkbuttons. these panels are contained in a <asp:updatepanel> control the page_load event fills out the first panel with linkbuttons and assigns cooresponding commandName commandArgument for them, that works. then the first panel's linkbuttons triggers the command and fill out the second panel with linkbuttons, that works too. then the seond panel's linkbuttons are supposed to fill out the third panel with linkbuttons, but that doesn't work anymore, and it seems like doing the page_load event again and filling out the first panel and the second panel's linkbuttons disppear, just like the first time the page is loaded.

I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?
Also if i can ask another question, I'm also wanting to know whether the updatepanel can support feed-in like facebook ? What I'm wanting to do is have something that updates the screen (like the update panel), and items within this panel contains links. When the user clicks on the link it shows a modal div, giving the user options to do some updates. Once the user clicks submit, then this makes a call to the server to update the details then also update the panel. Within the panel I also want to move some of the div elements using javascript (causing the drag and drops to save to the database).
I have MP inside MP but when i am using UpdatePanel not working. No ajax, page is reloading like before...

I have one button and one textbox inside a updatepanel. On button click I am adding an alert script. But when I use the ViewSource by right clicking on the page, then the alert script is not generated.
[Code]....
[Code]....
But if I remove the the UpdatePanel then the script is generated and the alert message is displayed. What should I do to register the script when using updatepanel.
I know that there are hundreds of posts out there on this problem, but I have tried everything (I think) and I still have not resolved it. If I remove the update panel everything works fine.
I've tried :
[Code]....
And every other variation I can think of.
Here's the ClientSide code:
[Code]....
And here's the Server Side code:
[Code]....
<script type="text/javascript">
$(document).ready(function () {
$(".autotab").keyup(function () {
if ($(this).attr("maxlength") == $(this).val().length) {
var index = $(".autotab").index(this);
var item = $($(".autotab")[++index]);
if (item.length > 0)
item.focus();
}
});
});
</script>
the above autotab code not working if required textboxes in updatepanel. how to solve it.
I have dropdownlist autopostback and AsyncFileUpload both inside UpdatePanel After I selected Item in dropdownlist to postback,AsyncFileUpload is changed it's size and it can't upload After Dropdownlist postback
This is my code
[Code]....
i have a DropDownList, which is inside an UpdatePanel. Now my problem is that, for example, lets say there are 3 item, Item1, Item2, Item3.
Now Item1 is the default, and i have code in codebehind that gets the value of the selected DropDownList, so for example, my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "UPDATE Items SET ItemSelect = @ItemSelect";
using (SqlConnection myConnection = new SqlConnection(connectionString))
{
myConnection.Open();
SqlCommand HubInsert = new SqlCommand(insertSql, myConnection);
HubInsert.Parameters.AddWithValue("@ItemSelect", DropDown1.SelectedValue.ToString());
HubInsert.ExecuteNonQuery();
myConnection.Close();
}
Now the problem is that, once it is in an update panel, when you change the list to another item, so for example, i changed the list to "Item2", it will still be showing the first value of "Item1", i could have used Autopostback to get what i need, but then i wouldnt see the point in using update panel, since i dont want my page to flick.
Is there a way, or code to write that whenever the value of the DropDownList is changed, and i click my button, it will actually get the currently selected value, and not the virst default value,
at last project i need to deploy cascading dropdownlist without using web serive or cascadingDropDownList Extender
i try to do this using updatepanel :D this work , but at many times that apear my computer and my internet Explorer as busy and hang and i can not do any thing untill populate the second dropdownlist :(
is there any way to avoid that and to view a wait message until populate the second dropdownlist , i mean is there a sample code for doing that
here is my code

I have a ReportViewer with drillthrough function report and it takes 3 mins to run the report on buttonclick.So I have enclosed ReportViewer with AJAX update panel and give a wait.gif ProgressTemplate.
After this change onbuttonclick now the wait gif appears and then the report displayed as desired after 3 mins. However, now the drilldown function of the report is not working anymore and view error it says "ClientReportxaxsaacscdcsdci678686 is not defined.
I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.
I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..
<asp:UpdatePanel ID="UpdatePanel1" runat=server><contenttemplate><triggers><asyntrigger ID= "Submit"> /> /> />
<asp:updateprogress ID="Progress1" unat=server AssociatedUpdatePanelID="UpdatePanel1"><Progresstemplate>Progress.... />/>
<asp:button ID= "Submit" runat=server >
I have nothing for updateprogress in code behind. Am i missing or doing somethign wrong here?
We have an updatepanel in our site and there are a number of linkbuttons in it. Please note that the site works fine in all browsers without proxy the proxy changes the url from for instance [URL] to 0-[URL] it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is "Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; Tablet PC 2.0; InfoPath.1; .NET4.0C; .NET4.0E) Timestamp: Sun, 13 Mar 2011 20:38:58 UTC

I have no idea what goes wrong here, it seems that IE can't parse the response?

The following is not working (does a full postback). Note: HTML tags inside updatepanel. We can' t have HTML tags inside updatepanel? If so, what's the work around?
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<td><asp:DropDownList ID="ddlDEPT_ID" runat="server" AutoPostBack="true"></asp:DropDownList></td>
<td><asp:Label ID="Label5" runat="server" Text="Sub-Department:"></asp:Label></td>
<td><asp:DropDownList ID="ddlSUB_DEPT_ID" runat="server"></asp:DropDownList></td>
</ContentTemplate>
</asp:UpdatePanel>
The following works fine. AJAX in action.
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:DropDownList ID="ddlDEPT_ID" runat="server" Width="200px" AutoPostBack="true"></asp:DropDownList>
<asp:Label ID="Label5" runat="server" Text="Sub-Department:"></asp:Label>
<asp:DropDownList ID="ddlSUB_DEPT_ID" runat="server" Width="200px"></asp:DropDownList>
</ContentTemplate>
</asp:UpdatePanel>
I have updatePanel in my ASP.NET 2.0 (migrated from ASP.NET 1.1) web app. It doesn't work as it always postback instead of callback. I already set<xhtmlConformance mode="Transitional" /> but still not working. Previously, it just working.
