radconfirm() and radprompt() codebehind HELP

[German]

Is there any way to execute radconfirm and radprompt through codebehind in VB??
I need to re-use the variable that will be entered/clicked by the user.

[Stuart Hemming]

I can't help you with a code example, I don;t know VB from a hole in the head, but in C# I'd write

RadAjaxManaer1.ResponseScripts.Add("radconfirm('Are you sure?', confirmCallBackFn);");

Assuming that there was a RadAjaxManager on the page. If there's not, something like ...

ClientScript.RegisterStartupScript(this.GetType(), "confirm", "<script type='text/javascript'>radconfirm('Are you sure?', confirmCallBackFn);</script>");

Thanks for your reply. I've gotten the radconfirm() and radprompt() to display the way i wanted them to.
My next question is the following: From the aspx.vb page, Is it possible to grab the variable the user enters into a
radprompt or radconfirm. For instance, grabbing that variable and inserting it into a database or do anything else within the vb page.
This is an example code for my radprompt:

 

Dim

 

radconfirm As String = "<script language='javascript'>function f(){radconfirm
('This is a <b>Confirm Window</b>!', confirmCallBackFn, 300, 150); return false;
Sys.Application.remove_load(f);};</script>"

 

 

 

 

Page.ClientScript.RegisterStartupScript(Me.[GetType](), "radconfirm", radconfirm)

 

 

 

 

 

 

 

Dim confirmCallBackFn As String = "<script language='javascript'>function confirmCallBackFn
(arg){radalert('Prompt returned the following result: ' + arg + ' ', 250, 150, 'ANSWER TITLE');
Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>"

 

 

 

 

 

Page.ClientScript.RegisterStartupScript(Me.[GetType](), "confirmCallBackFn", confirmCallBackFn)

German,

One way would be to put the value in to a hidden input field in your callback function and then force a postback (or call back if you're using Ajax). You can then get the value in your postback handler on the server.

Hope this helps.

Thank you, your reply was very helpful in what i was trying to accomplish.
I'm currently using a GridView to display data and I have created a linkbutton
to delete any row of information. I have gotten a regular confirm prompt to display
asking the user if they would like to delete. The options "Yes" and "No" work well with a regular
confirm window. I want to apply a RadConfirm to the gridview as opposed to the regular
confirm window. I have gotten the radConfirm to display, however, the "Yes" and "No" buttons
do not work accordingly. This is the code I have to display my radconfirm:

 

<

 

asp:TemplateField ShowHeader="False">

 

 

 

 

<

 

 

ItemTemplate>

 

 

 

    <asp:LinkButton ID="LinkButton1" runat="server"
     CausesValidation="False" CommandName="Delete"

 

 

 

 

     OnClientClick="radconfirm('Delete ??',300, 400, null, 'TITLE'); return false;">Delete</asp:LinkButton><br style="clear:both" /><br 
     style="clear:both" />

 

 

 

 

</ItemTemplate>

 

 

 

 

 

</

 

asp:TemplateField>

German,

I can see why this /won't/ work, and that's 'cos you don't have a callback function in your radconfirm call; without that there's no way to get at the result of the confirm dialog.

I'm not convinced about the following, but if you try using the same basic idea you used before to save the radconfirm result, you can handle the postback and do your delete then.

As I say, I'm not 100% sure that this is the best way to do this, but if you don't get it to work you can either wait for a grown-up to wander passed and answer it or ask over in the Grid forum where there are more clever chaps than you can wave a stick at.

Thank you for your reply. It helped out alot. Is there any way to modify the Skin style? given
that the radprompt is composed of a LinkButton and javascript. I'm also using a GridView and not
a RADGridView. And is it possible to execute a radprompt much the same way as in the
earlier example? and use the input for whatever?

Hi German ,

In reference to your questions :

• You could easily change the look and feel of the predefined dialogs by declaring the templates in the RadWindowManager as described in this help page.
• Yes, you could use the same approach to open the radprompt dialog. Please note however that this is a custom solution and you need to implement it yourself

I hope this helps.
