I am using a update panel in my webpage. I am having a treeview in it . The css property of the Treeview before updating is different from after.
View 2 RepliesI have a page with 2 update panels.
Controls in the update panel holds a listview and each row here has a button. This button fires a FancyBox (modal dialog) When closing this a call to the onClosed event is triggered like here:
[Code]....
There is two of these sections one for each update panel. The problem here is that this 'Page.ClientScript.GetPostBackEventReference' actually updates the wrong update panel!It is always updating the first updatepanel on the page, and I cannot figure out why this is. The two update panels areencapsulated in its own user control, but still the first update panel is always fired.
I have a ListView control that is inside of an update panel. I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button. The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected. I then can go to another page, come back and the new data is there. I'm not sure what I missing. Please see the code below.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:ListView ID="ListView2" runat="server" DataSourceID="sdsrcMessageComments" DataKeyNames="MessageId"
ItemPlaceholderID="PlaceHolder2" EnableViewState="False">

I am working in asp.net 4.5 with VS2013. I have two usercontrols in my aspx page and in my first usercontrol i have gridview with button inside update panel and if i press the button it should pass the value to second userconrol and based on the value i will do some db operation to bind the controls in second usercontrol.
I am wondering is it possible to achieve using AJAX? I need to do this with partial postback without posting entire content of the page.
I use a hidden Div to print some bills to users, whithin that div there is a updatepanel containing two different datalists.
In client code it calls code behind to do bindings and it does successfully , on success function it clicks some button for updates to take place, here is the problem. updates are not happening.
Is it concerning with using datalist in update panel? for your better digging into problem code follows:

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 am using C# for my programming. I am facing issue, that my hidden variable value is not being updated when it is in update panel. Please see below code for aspx:
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick">
</asp:Timer>
<input type="hidden" runat="server" id="hidCurrentDate" value="" />
<input type="hidden" runat="server" id="hidTripIds" value="" />
<input type="hidden" runat="server" id="hidTripDetails" value="" />
<asp:UpdateProgress ID="uprogTrips" runat="server">
<ProgressTemplate>
<span style="display: block; text-align: center">
<p style="font-family: Verdana; font-size: larger; font-weight: bold;">

<asp:AsyncPostBackTrigger ControlID="cbPageOptions" EventName="CheckedChanged" />
</Triggers>
</asp:UpdatePanel>
and below is the code where I am trying to update one of the hidden field with my CS code. Interesting, when I am trying to debug its showing all the values, however when I see it f on page source it doesn't give any value. Here is my aspx.cs code:
protected void Timer1_Tick(object sender, EventArgs e)
{
DataTable dtTrips = null;
WEX.Prototype.Data.TripDA tripDA = new WEX.Prototype.Data.TripDA();
string tID = hidTripIds.Value;
string[] tripIDs = new string[1000];
tripIDs = tID.Split(',');
foreach (string tripID in tripIDs)
{
TripSummaryBO tripSummaryBO = tripDA.getTripSummary(Convert.ToInt32(tripID));
if (tripSummaryBO.tripLastEditedOnDate > Convert.ToDateTime(hidCurrentDate.Value))
{
WEX.Prototype.Service.WSProxies WSProxies = new WEX.Prototype.Service.WSProxies();
dtTrips = WSProxies.Build();
Session["AllTrips"] = dtTrips;
dtTrips = (DataTable)Session["AllTrips"];
if (dtTrips != null)
{
if (cnt==0)
{
hidTripDetails.Value = ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
}
else
{
hidTripDetails.Value = hidTripDetails.Value + " <br/> " + ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
}
BuildGridViewControl(dtTrips);
cnt = cnt + 1;
}
}
else
{
//upTripsGrid.Triggers.Clear();
PageInit();
}
}
}
In my web page, i have user control inside update panel, user control refreshed every time update by update panel.
View 3 RepliesI 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?
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.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
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.

I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
Above is my code to call a hidden DIV:

And above the html for the DIV:

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.
is there any other way by which we can update a section in page except Update Panel?
View 1 RepliesWe 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.
How do we achieve this ?
I have an update panel on my page. Within that is a repeater which has a user control in it. Inside the user control I allow an update to the datasource of the repeater. I am able to successfully save the data to the database but when I call the .Update method of the update panel, the user control is blank. If I proceed to refresh the page, the data appears with the changes I made. why the data is disappearing when I call the .Update method?
View 1 RepliesI have a user control which acts as a footer for my website and uses java script jqdock.js to show apple type bottom menu. I added an update panel to the usercontrol. What problem I am having now is, it works fine initally but once I click the mail button which is in the usercontrol , the whole user control dissapears, after postback i guess. below is the usercontrol and code view:
enter code here
public void Page_Load(object sender, EventArgs e)
{
// Page.ClientScript.RegisterClientScriptInclude("bottomMenu", "../js/jqDock.js");
ScriptManager.RegisterClientScriptInclude(this,this.GetType(),"bottomMenu", "../js/jqDock.js");[code]....
I am having a problem with partial postback through update panel, Update panel is not working properly in my asp.net app with IE8. But app works fine if i switch to compatibility mode of IE8.
View 5 RepliesI 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 a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..
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.
in one table
<asp:UpdatePanel ID="Operations" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="txtOperations" runat="server" Font-Names="Code128bWin" OnTextChanged="OperationEventHandler" AutoPostBack="true"></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID = "txtOperations" EventName="TextChanged" />
</Triggers>
</asp:UpdatePanel>
and a label in other table
<asp:Label ID="lblOperation" Text="OperationID not Valid" runat="></asp:Label>
and the code behind page is
protected void OperationEventHandler(object sender, EventArgs e)
{
GridView GridViewValidOps = new GridView();
GridViewValidOps.DataSource = TB.ValidateOperations(txtOperations.Text);
GridViewValidOps.DataBind();
if (GridViewValidOps.Rows.Count <= 0)
{
lblOperation.Text = "OperationID Not Valid";
}
}
Is there a way to use the same update panel for the label , because i want the value of the label to be updated if the user enters wrong value.
