Hi,
I'm facing problem when i load page with dynamically created controls. This happens if i save a arraylist in viewstate.
ViewState["Delim"] = arrList;
I searched the net, and found that we can save arraylists in viewstate, and that try saving it in page_preRender. I did so, but same issue. If i save some string in viewstate instead, it doesn't have any problems loading the dynamic controls.

Anyone can help me here, to resolve this?

Thanks,
Deepa

Where did you create those control ? You should have to create dynamic control before page_load to holds the ViewState.

I guess, Before PreRender, all viewstate data are saved. Smile | :)

Hi,
Dynamic controls are created in page load. Also, is it something to do with declaration of Arraylist? I declare it as global variable.

I tried saving the arraylist object in page load after controls are generated. But still same problem.

Please note, the arraylist contains objects of a particular class. Is it a problem?

I dont get it...it goes to the Application_Error event in global.asax.cs.

How do i resolve this? i need to store the arraylist in viewstate, because i require it on one button click event.

As I already mention Dynamic Control Can be created on Page_Load, BUT If you create dynamic control on Page_Load() or after, It will not able to load Postback data and View State Data. Because, LoadViewState and LoadPostback data called before the Page_Load() in ASP.NET Page Life Cycle.

List<string> availableResources = new List<string>();
string resourcespath = Path.Combine(System.Web.HttpRuntime.AppDomainAppPath, "App_GlobalResources");
DirectoryInfo dirInfo = new DirectoryInfo(resourcespath);
foreach (FileInfo fi in dirInfo.GetFiles("*.*.resx", SearchOption.AllDirectories))
{

string cultureName = Path.GetFileNameWithoutExtension(fi.Name);
if (cultureName.LastIndexOf(".") == cultureName.Length - 1)
continue;
cultureName = cultureName.Substring(cultureName.LastIndexOf(".") + 1);
availableResources.Add(cultureName);
}

List<CultureInfo> result = new List<CultureInfo>();
foreach (CultureInfo culture in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
{

if (availableResources.Contains(culture.ToString()))
{
result.Add(culture);
}
}

AvailableCultures = result.ToArray();

CurrentCulture = DefaultCulture;

if (!result.Contains(DefaultCulture) && result.Count>0)
{
CurrentCulture = result[0];
}
}

Why do you think that setting the culture on the server will translate your page into persian for you ?

It seems that user does not have the sufficient permission to access the database. Did you moved the database from development to IIS server ? Please check your database having the permission with proper user.

RichTextBox in web requires great knowledge on Javascript. I have once tried to create one RichTextBox myself. Its working but never used it anywhere.

Its always better of use free existing RichTextEditors, as they are mostly tested and better in performance.

Thumbs Up | :thumbsup:

Are you using AJAX Toolkit?
You can have a look into AJAX HTML Editor.
