Need to set Primary Key for insert

In our environment, we have an AppSequenceNumber table which maintains the next sequence number or primary key for the next insert of each table in the database, and a stored procedure that returns the sequence number and increments it in the database. Therefore, on each record insert for each of our tables, we must call this stored procedure which updates the AppSequenceNumber table and returns the sequence number which we use as our primary key in the record insert.

In my application, I am using a popup modal window to handle inserts. How do I capture the submit button click event on this form and call the needed stored procedure to update the database sequence number, insert the sequence number as the primary key, and perform the insert?

I am basing my application on the example at: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultvb.aspx?product=window

Your help is greatly appreciated.
Thank you.

Using Predefined Dialogs with Codebehind

Hello,

I can easily display a radalert dialog from my C# codebehind with the following line of code:

    
            RadAjaxManager1.ResponseScripts.Add(@"radalert('Record already exists.', 225, 110);");

I assumed that working with the confirm and prompt dialogs would be similar, so I tried the following:

    
            RadAjaxManager1.ResponseScripts.Add(@"radprompt('Are you sure?', promptCallBackFn;");

But I cannot get the radprompt to even display (at this point I am only concerned with displaying the prompt). Am I wrong in assuming that I can treat these dialogs identically?

Thanks,

Ajax

Splitter borders

Hi All,

I'm able to use bordersize="0" on a splitter to make the outer borders disappear. But inside that there is a sliding pane that I want to have a 1px border around - otherwise it looks kind of weird. I can do that via some CSS as per examples in this forum however if I had a second sliding pane on that page the CSS would apply to that as well even if I didn't want it.

I'm about to look into if I can incorporate some form of id based selection into the CSS tag but beyond that is there a way yet to set the borders within the slidingpane's tag?

EDIT:
Trying out the instance based CSS doesn't work - perhaps because the ID isn't what you specify in the CSS but rather made up from the parent splitter name too or maybe because my CSS is so rusty! The CSS I tried is shown below:

#Radslidingpane4 .RadSplitter .rspSlidePane .rspSlideContainer

{

border:solid 1px black;

}

Regards.

Jon

IOException file not found

I'm using the MultipleFileSelection="Automatic" in AsyncUpload (trail of 2010 Q2) to ensure multiple files can be uploaded. Everything goes well with the uploading of multiple files, but when I write the following code in the Button click event of my form I get an IOException (File Could not find file 'C:\{app dir}\App_Data\RadUploadTemp\3yvza1nr.zhh'.):

            foreach (UploadedFile file in AsyncUpload1.UploadedFiles)
            {
                business.AddPhto(file.InputStream);
            }

The weird thing is that I can see that temporary files are deleted when the postback happends. Sometimes all files are gone, sometimes all the files are there.
My question is: How do I use the uploaded files and what should I do to prevent deletion of temporary files before I have the chance to handle them.

Kind regards,

Michel
