I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
I am tring to make Panel1 visible first, then in five seconds, Panel2 is visible, then in another five seconds, Panel3 is visible.
Here is my basic code for this.

i have created an user control with a text box and a list control inside ajax update panel to create a control like the google search text box which floods the values as the user types in.
its working fine too...now whats my problem is that when i am trying to use two user controls that i created in the same page. when i am running the page am able to use only the second user control. when i start typing in the first control the focus control is getting passed to the second one automatically and i am not able to type in anything in the first control.
what can be the reason? am using only one script manager for both. the update panel is inside the usercontrol.
I got an update panel, inside it, there is a grid view, and the data on grid views appear based on certain condition, so the number of rows will vary.
I got the following code, which when the grid view's row count exceeded 50, it will set the panel's height to 700px and with a vertical scroll bar. If it is lesser than 50 rows, it should reset the height.
On line 1, I actually wanted to reset the height, but somehow, it will set the panels height to 0. I tried alot of other values as well, and I dont think this line is helping.
The reason I want to reset the height is that I wanted the panel to expand according to grid view's row. And the reason I set to 700px is because i wanted to control the page viewability.

I want to create adynamic number of panels inside td in atable depending on number of items in dropdownlist ex (if dropdownlist have 5 items i want to create 5 panels)Each panel contans :Table that consist of 1- Fist row will be header that will be the title2- Second row will consist of number of cells depending on text for a label (ex 3,4,5 ,...)

even though I am updating the update panel place holder with new data, on the screen the old data will be shown.
A group I am in at school is developing a website for a client. It needs to be able to send weekly emails out to all users, as well perform many other scheduled tasks.My question is: what is the best way to fire events from classes within the solution with a timer? I've read that a Windows Service can be used...?
View 2 RepliesI've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
i just want to use a calendar with events like date selection update,delete,creat events. and i want to do this with sql server 2005. I started my project with webApple.

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 have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode.Â
I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.
i am attempting to use javascript to update the chart, because how i have setup now causes the chart to just disappear. Here is the code i have now: I am calling the chart to page using: on default.aspx
[Code]....
Code on the dataURL_Infrasturcture_Capacity.aspx page:
[Code]....
PROBLEM: So how would i update this using an update panel and timer. Currently when i do it the chart just disappears on update. I believethis is due to the fact that i am calling a dataURL. How would i get this to work javascript?
What is the best way to update data constantly on the client using asp.net Timer + Update Panel, or I need to use Reverse AJAX for that?
View 3 RepliesI am having a weird issue. I have a floating login div that I set visible through javascript/css when someone clicks the login button on my app. I have 4 field validators on that div. when I click the login button with all 4 required fields blank, the *'s that I chose as the required field validators text property show up fine and the summary text shows fine as well. But, when I cancel out of the div with the text still showing, the div hides and a couple of the validators text is still visible overlayed on my site. Its strange because the summary text dissapears just fine.
View 3 RepliesI created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?
I have a popup window that is displayed from the main form. I use a timer to refresh the data in an update panel on the popup page. The users keep the page open but ypically go back to the main page which then covers the popup. The problem I'm having is every time the timer event occurs, the popup page jumps to the forefront. How can I perform the updates without the page coming into focus automatically?

i have 4 update panels, and 1 of them updates after a button has been clicked, and the other 3 panels contain other buttons, but what i would like to do is that, when the button is clicked, how would i make it ONLY trigger for that update panel, as it updates the whole page, and is affecting my Textbox on the page, which is also in an update panel. how i could make just that specific panel update, and not all of them?
View 2 RepliesI have the usual problem of dynamically created usercontrols not hitting the event handler for a linkbutton inside the control, but I've checked the usual problems and I can't work out what's wrong. I'm calling a function to create the controls at the bottom of my page.load (although I did try page.init as well just in case) outside of my page.ispostback check, and I'm setting the controls id's to a fixed name which is consistent across postbacks. Any ideas what's wrong?

I basically have an update panel being dynamically populated with a LinkButtons after a postback. This link buttons are being assigned an event. Now when I click the button the event is not firing. As I understand it the event is not firing because I'm not creating the button in the Page_Load event and therefore .Net does not remember this controls were created after postback. I'm not able to create these controls in the Page_Load as they are dependant on user input. So my question is how can I create these controls dynamically and have the page retain them and their events after postback?
View 4 RepliesIs it possible to use an UpdatePanel that has like a few text boxes, and a search button, and then perhaps another UpdatePanel that has a gridview in it to return the results of what was searched. When the user clicks search it hides the boxes, and displays the gridview. Can I do this with UpdatePanels? I am using c# for my coding. Or should I be doing this another way?
View 3 RepliesAs far as I understand UpdatePanels, they should be invalidated separately, i.e. triggerring one UpdatePanel should not touch the controls of the other panel. It does work so for controls outside of any UpdatePanels, however those which are inside ANY UpdatePanel are touched by triggering ANY UpdatePanel:
<form id="form1" runat="server">
<asp:ScriptManager ID="SM1" runat="server"/>
<div>
