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.
View 3 RepliesMy popup panel is disappearing everytime the timer ticks in an updatepanel.How can i solve this problem please friends.
View 5 RepliesI 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.
View 4 RepliesVS2010 ( 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.

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 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 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 simply want the UpdatePanel NOT to give a full postback, even without a timer.
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.
View 9 RepliesI 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 am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
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.
i want to know that how the timer works in asp.net.?
View 1 RepliesIt looks that the old SqlHelper class from the Microsoft Enterprise Library has been mostly replaced by the Database class which is included in the new Enterprise Library version 5.
I have a very simple and trivial example:
using Microsoft.ApplicationBlocks.Data;
private void PopulateCheckBoxGroup()
{
const string strConnTxt = "Server=(local);Database=DataBindTests;Integrated Security=True;";
const string strlSql = "select Technology from PreferredTechnology where ParentId = 1";
CheckBoxList1.DataSource = SqlHelper.ExecuteReader(strConnTxt, CommandType.Text, strlSql);
CheckBoxList1.DataTextField = "Technology";
CheckBoxList1.DataBind();
}
I want to show a message when there's no data in my datalist. I found the following, but, I get an error on the bool. If you have another way to do this, great, but, I'd also like to try to do it this way as a learning experience.
<asp:DataList id="DataList3" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:HyperLink ID="ID" runat="server" target="_parent" NavigateUrl='<%# "Employment_detail.aspx?"%>'

</ItemTemplate>
<FooterTemplate>
<asp:Label ID="lblEmpty"
Text="Nothing here." runat="server" Visible="true">
%>Visible='<%#bool.Parse((SqlDataSource1.Items.Count==0).ToString())%>'> </asp:Label>
</FooterTemplate>

I am using .net 3.5 and I make Windows Service Where my windows service is starting properly and stopping also properly. And I put timer control in that in which interval 1000. But the event is not getting raise what can be the problem OnStart I am makingit timer1.enabled=true and Onstop I am making timer1. enabled =false for debugging purpose I am writing Log Entry at beginning of timer_tick event.
View 2 RepliesHere upon loading the page there will be 4 panels having their own timer controls (having interval 1000) for incrementing a variable "a". But the problem is that, as I have used static variable that's why all the timer's are sharing the variable "a" and creating a problem like each panel's label showing a value incremented by 4 after every second. Can any body solve this problem..
