AddAjaxSetting Object reference not set to an instance of an object

Hi

I am currently working on upgrading our application to your latest controls. We are moving from using Telerik.WebControls (Class controls) to the Telerik.Web.UI (Ajax controls)

I have got the application compiling and I am working through the errors the application is throwing.

I have come into a stumbling block when the pages load which contain the below syntax:

RadAjaxManager.AjaxSettings.AddAjaxSetting(RadAjaxManager, updatePanel, AjaxLoadingPanel);

Obviously the parameters that are passed are different between pages however i am constantly getting an Object reference not set to an instance of an object error message and have been unable to find any relevant help on this.

The AddAjaxSetting is varying between being defined in the Page_Load, On_Init and On_PreRender methods.

If you need any more information please let me know.

Regards,
Jonathan

How do i validate "valid" decimal value with Radmaskedtextbox

Hi Team,

We are using masked textbox in few important places in our system for different type of input validation.

Now, i am dead stuck with how to i validate the "Valid" Decimal value with masked text box.

"#" or "9" format must need the that many number of digits.

e.g. valid decimal numbers are:
111.124
11.12455
11111.12455

Making mask "######.######" like that, must require user to type in leading "0(zero)", which is real pain.

If you could be of any help solving this mystry will be great help.

Thanks,
J. Ramesh

Adding scripts with RadScriptManager

Hi, I’m updating an ASP.NET AJAX application so that the jQuery library loaded by the Telerik.Web.UI assembly can be re-used by other scripts. I have two questions which I’d appreciate some advice on:

I have a RadScriptManager on my master page and need to include a private javascript file that can be used by all content pages. Should I include the script as a reference within the RadScriptManager or should I use conventional script tags after the RadScriptManager? I’ve illustrated both methods below. Both seem to work but what is the recommended approach?

METHOD 1
<telerik:RadScriptManager ID="rsmMain" runat="server" >
<Scripts>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
</Scripts>
</telerik:RadScriptManager>
<script type="text/javascript" src="../Scripts/Utility.js"></script>

METHOD 2
<telerik:RadScriptManager ID="rsmMain" runat="server" >
<Scripts>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
<asp:ScriptReference Path="~/Scripts/Utility.js" />
</Scripts>
</telerik:RadScriptManager>

My second question relates to adding a client-side script from a page programmatically. Previously I used the RegisterStartupScript() method of ClientScriptManager to add a script from code behind but I note from some forum posts that it’s suggested you should use RadScriptManager.RegisterStartupScript() instead. What’s the difference and is there a recommended approach?

Regards, Ian

Auto rebind after command execution

Hi!

I am using RadGrid. There is GridButtonColumn(CommandName = "DeleteCommand") for deleting a row.

onCommand: function (sender, eventArgs) {

var commandName = eventArgs.get_commandName();

if (commandName == "DeleteCommand") {

var dataItems = eventArgs.get_tableView().get_dataItems();

var dataItem = dataItems[eventArgs.get_commandArgument()].get_dataItem();

deleteRow(dataItem);

}

It works, but after deleting grid is rebinded. How can I turn off auto rebind?
I've found "Commands that invoke Rebind() implicitly" topic and change the command name. But It doesn't work.
I tried to use eventArgs.set_cancel(true). But It doesn't work too.

Thanks for your help!

"A generic error occurred in GDI+"

Hello Team,

I am using Telerik Image Editor. I want to save and overwrite file on custom path using RadImageEditor_ImageSaving Server side event.

when I modify image and try to save it on same path, I am getting error "A generic error occurred in GDI+"

Please Note: I want to maintain only two versions of file 1) Original file 2) Updated file

protected void RadImageEditor1_ImageSaving(object sender, ImageEditorSavingEventArgs args)
{

var context = new EBABBLEEntities();

Account Lo_Account = (from acc in context.Accounts where acc.Id == cls_Session.User.Id select acc).FirstOrDefault();
System.Drawing.Image newImage = args.Image.Image;

string filename = Path.GetFileNameWithoutExtension(ImageURL);
int indexer = filename.IndexOf("_Edited");

if (indexer != -1)
{
newImage.Save(Server.MapPath("~" + Lo_Account.files_path + "/My_DigiGLUS/") + filename.Substring(0, (filename.Length) - 7) + "_Edited" + Path.GetExtension(ImageURL));

}
else
{
newImage.Save(Server.MapPath("~" + Lo_Account.files_path + "/My_DigiGLUS/") + Path.GetFileNameWithoutExtension(ImageURL) + "_Edited" + Path.GetExtension(ImageURL));
}

args.Cancel = true;
DigiId = Convert.ToInt32(Request.QueryString["digigluId"].ToString());
DigiGLUs Editdigiglu = (from digi in context.DigiGLUs where digi.Id == DigiId select digi).FirstOrDefault();

if (indexer != -1)
{
Editdigiglu.NewImageName = filename.Substring(0, (filename.Length) -7) + "_Edited" + Path.GetExtension(ImageURL);

}
else
{
Editdigiglu.NewImageName = Path.GetFileNameWithoutExtension(ImageURL) + "_Edited" + Path.GetExtension(ImageURL);
}

context.SaveChanges();

}

Please review the code, help me to find where I am doing wrong. I really appreciate your help to solve this issue....

Wildcard $find for control in ContentPlaceHolder for ASP.NET

Hi there

Can anybody assist with this problem? I have a radEditor in an ASP.NET page using a MasterPage, which as you will know, uses ContentPlaceHolder controls to hold other controls, and which also prefixes the declared control id with that of the ContentPlaceHolder in question, e.g., from a server-side id of 'myRadEditor' the client-side id would end up being something along the lines of:

'ct100_myContentplaceholder_myRadEditor'

When it comes to using the client-side $find command, all of the examples I can find show the use of the following syntax:

<%= myServerSideID.ClientID %>

but as far as I know, this is only valid for Javascript embedded within the <SCRIPT></SCRIPT> 'node' of the the .aspx file. However, I have a set of external Javascript script files added dynamically and programmatically, rather than specified declaratively in the aspx files in question.

So my question is, how would I go about using the $find command to get a reference to a radEditor control, or indeed any telerik control, using a wildcard search for the server-side id (e.g., 'myRadEditor') from within an 'external' Javascript file, given that the

<%= ... %> syntax is not available?

Thanks very much if you can advise!

Regards
