Is it possible to use AJAX and an update panel and create server-side controls such as checkboxes, buttons, and radio buttons (asp server side) that is created when another server-side control (that which exists outside the update panel) calls them?
secondly, how do you keep them from re-appearing after a postback?
When I do a postback, the controls in the update panel disappear.
How to Dynamicly generate HTML from server side ?

I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
View 1 RepliesHOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.

I am trying to allow for multiple selection check boxes that are created dynamically.
The Following code is written for each row in the dataTable (I print it as HTML code)
<input type='checkbox' name='multiCheck' id='chk{1}' value='{1}' runat='server'/>
however, on the server side (after postback) I can't read them from the Request Object. How do I "mark" them so I can read them at the postback?
protected void DeleteSelection_Click(object sender, ImageClickEventArgs e)
{
int multiIdsToDelete = Request.Form["multiCheck"]; <-- In the Future will be added to an array so I can do the delete for each row selected.
}
I need to create a .pdf file which can download by client clicking on the link in my web site. That pdf should be generated using stored information in database. It has different types of fonts which has not installed in client machine and only installed in web server. In this case, I'm not interesting to use crystal report or any other third party components that need to register to use and has some limitations.
How can I do that using ASP.NET with C#?

It's for a simple CMS where i have the basic site core and then some extra modules that i have lying in a seperate folder. If the parsing of the requested url demands a modulefile, the idea was to search for that file and if it existed, run the code and post it back to the site core.
In classic i was forced to manually (ugh..) add includes with the filenames statically written in the file-property.. That could be the way to do it again, but is there another way? Something like server.execute in classic, i just need to be able to send site core variables to the external file (without sessions if possible)
I am trying to create a composite control - A textbox, gridview and a button. When I create the grid dynamically, I use my function GridViewDataBind() that will basically create the gridview at runtime and bind it with data. In this method, I add a blank column (first column for expand/collapse image), databound columns (using custom Itemtemplate), a placeholder, then a new html row/cell and a child gridview. I want to know how can I add these html rows/cols to my gridview. Here is the code:

Not sure if the approach is right and if I was able to explain my problem?
The scenario is this. I have a long page that has a scroll bar. I'm us an Ajax ModalPopupExtender and that too is very long and has a scroll bar.
The problem I'm seeing is that in IE when a user scrolls the modal popup window, when it reaches the bottom it also scrolls to main window which has a really ugly user experience.
So what I want to do is, through server side code, I want to dynamically change the body css overflow from auto to hidden and I can't seem to find a way to make that happen. I've tried a number of approaches and none of them seem to work.

I'm trying to use MS IME on a server to retrieve some Japanese info in a silverlight app. The app accesses to the server by using WCF, but when calling a CoCreateInstance to create a IFELanguage2, it gives me -2147467262. The same code I'm using on the server actually works pretty fine on a WPF app.
Here is the code,
// ...omit
Guid imeGuid;
int errCode = Ole32.CLSIDFromString("MSIME.Japan", out imeGuid);
WinBase.CheckError(errCode);
Guid feLangIID = new Guid(Constants.IID_IFELanguage2);
IntPtr ppv;
errCode = Ole32.CoCreateInstance(imeGuid, IntPtr.Zero, Ole32.CLSCTX.CLSCTX_ALL, feLangIID, out ppv);
WinBase.CheckError(errCode); // errCode is 2147467262
IFELanguage IfeLanguage = Marshal.GetTypedObjectForIUnknown(ppv, typeof(IFELanguage)) as IFELanguage;
errCode = IfeLanguage.Open();
WinBase.CheckError(errCode);
// ...omit
Do I need to setup anything to use the MS IME on a server side? I'm running the app on the following environment, IIS7 .NET Framework 4.0 Windows 7 pro 64 bit VS2010

View 4 RepliesI've created a ScriptService / ScriptMethod that uses a custom class as an input parameter but can't figure out how to create an instance of the object on the client side.I thought that when I used ScriptManager and Ajax before the ScriptManager registered my server side classes for me or am I completely mistaken?
View 4 RepliesIn your opinion, what's the best way to create the server side to a pure Javascript application with ASP.NET? WCF rendering JSON? IHttpHandler? Update Like GMail, that runs in the browser (with a lot of Javascript) and submit and receive data with Ajax, for example.
