.net - Timer In UPdatePanel Changes SelectedIndex Of RadioButtonList?
Nov 16, 2010
I have a situation where I have a page in ASP.NET. In this page I have a RadioButtonList, which contains 5 solutions to a question. The RadioButtonList is feeded by an object, which has these solutions.I have a timer, which runs every second, to update loads of graphical controls. Everything works, BESIDES the RadioButtonList selection.This is what happends:
When I select an item in the RadioButtonList and the timer tick, the selectedIndex of the RadioButtonLIst value is 0. This means it selects the FIRST item in the list. However, IF I click an item, which has a "Yes" value in it (the value field can either have "No" or "Yes", it will stay at this item.First of all, I have NO idea why the timer re-select my RadioButtonList selection, as any other Page_Load event does nothing. And even if that makes sense, I have no idea why it just re-selects SOME of the answers..I have the following HTML code:
<asp:Timer ID="AssignmentTimer" runat="server" Interval="1000">
</asp:Timer>
<asp:UpdatePanel ID="FightUpdatePnl" runat="server" UpdateMode="Always" ChildrenAsTriggers="True">[code]....
When the timer ticks, the RadioButtonList re-select item 0. This is however not consistent, and sometimes it doesn't re-select.
I'd rather it didn't re-select at all! :)

I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.

I have a gridview in one UpdatePanel and a FormView in another UpdatePanel.
The FormView UpdatePanel refresh is triggered when the GridView SelectedIndexChanged event fires. This then displays the FormView. However when a user navigates to another page in the GridView or sorts the data then the GridView is refreshed and the SelectedIndex
is changed to nothing in the code behind via the GridView DataBinding event.
The FormView UpdatePanel does not refresh to reflect this. I have to manually set the FormView datasource to null and update the FormView UpdatePanel in the code behind.
My question is why doesn't my FormView UpdatePanel update when the SelectedIndex of the GridView is altered in the code behind.

is there any other method that is similar to updatepanel and timer control in asp.net? I need to auto refresh a "section" of the page silently like what updatpanel and timer do.

After loading updatepanel through Timer, i am unable to make any async request from the updatepanel.
sample aspx Code:
<asp:UpdatePanel runat="server" UpdateMode="Conditional">
<ContentTemplate>
<%--The Timer that causes the partial postback--%>
<asp:Timer runat="server" Interval="100" OnTick="Timer_Tick" Id="Timer1"/>
<asp:ImageButton ID="btnSaveEmployeePrevJobs" runat="server" ImageAlign="AbsBottom"
ImageUrl="~/Images/saveOff.gif" onmouseout="this.src='../Images/saveOff.gif'"

I have a quite strange situation where I have the following code:
<asp:Timer ID="GameClock" runat="server" Interval="5000" Enabled="true"
ontick="GameClock_Tick">
</asp:Timer>
<asp:UpdatePanel ID="ItemsUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
<Triggers>
NOTE THE TRIGGER IS COMMENTED OUT
<%--<asp:AsyncPostBackTrigger ControlID="GameClock" EventName="Tick" />--%>
</Triggers>
<ContentTemplate>
<asp:ListView ID="PlayerItems" runat="server" GroupItemCount="7"
onitemdatabound="PlayerItems_ItemDataBound">
<LayoutTemplate>
<table border="1" cellpadding="2" cellspacing="0" runat="server" id="tblProducts">
<tr runat="server" id="groupPlaceholder">
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<td id="Td1" runat="server" style="vertical-align:top; text-align:left; height:100%;">
<div>
<div id="category" runat="server">
<asp:Panel ID="ItemPanel" runat="server">
</asp:Panel>
</div>
</div>
</td>
</ItemTemplate>
<GroupTemplate>
<tr runat="server" id="productRow">
<td runat="server" id="itemPlaceholder"></td>
</tr>
</GroupTemplate>
</asp:ListView>
</ContentTemplate>
</asp:UpdatePanel>
This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):
protected void PlayerItems_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
ListViewDataItem dataItem = e.Item as ListViewDataItem;
if (dataItem != null)
{
BaseItem myItem = dataItem.DataItem as BaseItem;
Panel itemPanel = new Panel();
Literal firstLiteral = new Literal();
firstLiteral.Text += "<div id='smoothmenu1' class='ddsmoothmenu'>";
firstLiteral.Text += "<ul>";
firstLiteral.Text += "<li><img src='Images/Game/Items/" + myItem.ItemImageUrl + "' />";
firstLiteral.Text += "<ul>";
// Add all events bound to item into contextmenu
itemPanel.Controls.Add(firstLiteral);
foreach (Delegate del in myItem.Actions.Items)
{
Literal firstItLit = new Literal();
firstItLit.Text += "<li>";
itemPanel.Controls.Add(firstItLit);
MethodInfo methodInfo = del.Method;
string commandName = myItem.ItemId + "|" + methodInfo.Name;
LinkButton btn = new LinkButton();
btn.Text = methodInfo.Name;
btn.Click += new EventHandler(btn_Click);
btn.CommandName = commandName;
itemPanel.Controls.Add(btn);
Literal secondItLit = new Literal();
secondItLit.Text += "</li>";
itemPanel.Controls.Add(secondItLit);
}
Literal btnLiteral = new Literal();
btnLiteral.Text += "</ul>";
btnLiteral.Text += "</li>";
btnLiteral.Text += "</ul>";
btnLiteral.Text += "</div>";
itemPanel.Controls.Add(btnLiteral);
Panel panel = (Panel)(e.Item.FindControl("ItemPanel"));
panel.Controls.Add(itemPanel);
}
}
}
When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times.

If that is even the right combination of controls to use.. I have a page that will display a list of files that have been processed or processing.. its not really time sensitive, but would like for the page to refresh the gridview every say every minutelonger(not determined yet)Is that the most optimal way to accomplish this, i mean if you are on the page, i dont want you to have to hit refresh to see any new records or status changes to the existing records..

I have a countdown timer inside updatepanel. When it reaches 00:00:00, it processes a huge amount of data and that point of time, i'd like to disable the submit button outside updatepanel. Simple btn.enabled = false is not working.

GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.
I'm new at AJAX (that's my first problem - lol)
I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.

I don't understand what the problem is with this. It should be a simple operation yet it doesn't work.
I found samples on how to do this, when I apply the sample, it doesn't work.
In my page I have this:
[code]....
When I run the page, after 5 seconds it switches from the first image to the second image and never switches back to the first image.
When I debug with a break in the code-behind, it looks like the timer ticks twice for every tick. So, when the image is sample2, it then changes back to sample1 and then immediately ticks again and switches back to sample2 with no update-panel refresh in between.

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.
I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.
However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

On the home page of my site I have an UpdatePanel with a Timer which ticks every couple of seconds. Un-related to that I have a user login forum (username / password) If you are typing your username into the textbox while the timer ticks, it takes focus off the textbox.

I'm having trouble getting a RadioButtonList to correctly trigger the OnSelectedIndexChanged command. I've set AutoPostBack to true, and I've registered the control for AsyncPostBack. It triggers once, but then it won't again.

I have an update panel that has a timer set as the AsyncPostBackTrigger.In this Update Panel I have a repeater and in the repeater I have a few buttons which have on click events.The on click of these buttons does not appear to fire until the timer has tickedI have tried debugging and this is what seems to be happening, either way it takes ages for the button click to actually fire.

I have the same problem as [URL] However, the solution doesn't work for me since I'm using .Net 4.0 and xhtmlConformance is not there from start.
Basically, using a master page, the RadioButtonList still do the whole page postback even it's in the UpdatePanel. When I put the exact same code in a standalone page without a master page, it works as expected.

Am I missing a trick here ???
I am using VWD 2008.. I have a RadioButtonList with two options.
[Code]....
I also have an UpdatePanel
[Code]....
When the LoadingOption change it then has some code behind that at the moment changes the <asp:Literal ID="ItemName" runat="server" /> text.
If I don't have a Radiobutton selected when the page loads then all works fine. i.e. I can select either radiobutton and the ItemName updates correctly.... Whats the problem you may ask ????
Well I want to have one of the Radio buttons selected when the page has been loaded (like a default setting). So I do this <asp:ListItem Text="1kVA" Value="1kVA" Selected="True" />........ Here is my problem, When I select the other option (7kVA) the ItemName updates fine BUT if I then select the first option (1kVA) the ItemName does not update. I added another button that just does a postback. When the button is clicked the ItemName updates correctly. OK, fine but I don't want that. I want to be able to click on one option and the ItemName updates then click on the other option and the ItemName updates.
Have I missed something out ??
By the way if I set the <asp:AsyncPostBackTrigger ControlID="LoadingOptions" /> to <asp:PostBackTrigger ControlID="LoadingOptions" /> then it works how I want it apart from the reloading of the page, I would like it to update in Async Mode so it is seemless and no page reload.

I have a radiobutton that triggers the updatepanel to display or not..
when the page loads, i can select yes adn it displays, i can select no and it disappears.. i hit yes it reappears.. but after like the 3rd time going back and fourth testing the functionality, it stops displaying all together.
Is there something i need to look at to find out what is going on?
Here is my code on the page and code behind

VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

I'm searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.
I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.
