Something I have always wondered...Is there any difference in overhead between using Panel or HtmlContainerControl when needing to create a serverside container in ASP.NET.
HtmlContainerControl Container = new HtmlGenericControl("div");
Or
Panel Container = new Panel();
Also, is there differences in what is rendered in different browsers? I've noticed that Panel seems to render as a div in all browsers I have seen.
I have a set of code (noted below) in ProcessRequest(HttpContext context) in a generic handler .ashx file.
HtmlGenericControl holder = new HtmlGenericControl("div");
//Set holder's properties and customization
HtmlGenericControl button1 = new HtmlGenericControl("input");[code]....
Now as I am in a HttpHander, I want to get the HTML of holder control and write it through context.Respose.Write().
I'm dynamically creating a number of check box controls (CheckBoxList won't format as I need) by allocating HtmlGenericControl objects and adding them to table cells. A portion of my code is shown here:
[Code]....
The result is just as I want and, looking at the HTML, everything seems correct. However, when I try to read back the checkbox values on postback, Request.Form[id] always returns null. Part of this code looks like this:
[Code]....
I'm building a web app that assembles output on the fly, and I'm trying to find the right way to instantiate HtmlGenericControl to create a DIV tag. By default, instantiating creates a SPAN tag. Anyone know how to use it so it creates a DIV?
View 2 Repliesi am working on a dynamic tree menu with nested <ul><li>-Lists.
when building the nested list every <li> element should contain a <div> with a small icon and a css-style behind.
here is my code:
[Code]....
this way the result in the browser shows the name of every "aNavItem" but there are no icons. if i put the line to set the inner text of the div BEFORE adding the "imgMove" to it both things are shown - the name of the element and on the right the icon
the problem is that i want the icon to be on the left and then the text, but there is no icon at all with the code above (it looks like the setting of the inner text overwrites the already added image-control in the div-tag)
I have created an Asp.Net Ajax Server Control that will be dropped on several aspx pages. I have created an HTMLGenericControl within the OnInit method of the control. This control is a div. Within the code I also need to add an onclick event to a button so that this div is shown.
However, when I call divName.ClientID within the control to pass it to the javascript it doesn't include the part of the ID before the "divName" section of the rendered control id - ct01_ct01_divName.Here is part of the OnInit() method within the ASP.Net Ajax Server Control.[Code]....
I'm sure I'm doing something wrong here, but I cannot figure it out.
This is in my aspx page:

I have a page with several panels. panel1 has a drop down list to select client. panel2 has two drop down lists to select facility1 and facility2. I want panel 2 to be disabled (both facility1 and facility2 drop downs disabled) until a selection has been made in panel1 drop down list. when a client is selected from dropdownlist1, I want to enable both dropdown list2 and 3 in panel2.
View 7 RepliesI am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.
View 1 RepliesI have a panel and a background image. to stretch this image in the panel if the height is adjusting. I have tried to google this but have trouble find a solution for this.The image has the size: (647 X 158).
The only thing that will change is the height of the panel. Now it does repeat by default. no - repeat will probably only make the image its orignal size wich is not stretching it out over the whole panel.Otherwise I am thinking of change the size of the image itself in C#. [Code]....
I am using Ajax Control ToolKit's Accordian Control with 5 Accordian Panel. Contents of Accordian Panel are UserControl. Currently I have added all in the design mode, But it making my page slow because it loads all the content at a time. So, I want this to be dynamic. When User Click on Header of Accordian Panel, It loads the user control dynamically and also asynchronously.
I tried to put the user control under UpdatePanel which I placed under Accordian Content Panel but this is not working. Also I want to display loading images if getting slow response from server. how can I achieve it. It will be better if you provide an example.
Using VB, VS2010, I have a large image in a panel and want to be able to pop-up panels while hovering over it. This one large image is a picture of a lot of components that I woulld like to treat individually when I hover them. I have done this before by placing a transparent button in another panel that is absoultely positioned over the larger one. I have the button transparent with a border that shows up using hover in css. Everything works fine expcept that the panel does not show itself in the right place when viewiing in the browser window. It shows fine in design view, but shifts over while browsing in the browser. I have tried making all panels absolutely positioned. Still a problem. Is there a better way to put a panel over a panel?
View 1 RepliesI'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

View 1 RepliesI have a web page that I have a media control player on along with other controls in a table.It's a training video, so the controls are not visible.So the user can advance to the next web page,I thought I would have a button control inside an update panel with a time control so that the user had to watch the video and then the button control would appear after the video completed.I'm setting the button update panel to NOT visible and then turning it one when the time control elapses the same amount of time that the video runs.My problem is that when I set the visible property of the update panel to NOT visible it also makes the media player's panel NOT visible too.They are in two different panels.The medial player in a standard panel and the timer control connected witha separate panel that contains the button for the user to proceed. When I set the visible property to "true" the media player runs but the update panel with the button is visible also.

This is the code for the update panel and continue button that is in a separate table cell.I even split the table and so this is in a completely separate table but I still get the same behavior.
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 one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
