Hello,

A brief explanation of what I want to do:
I'm using a Custom AdvanceEditTemplate to update employee absences. For this I need a RadGrid inside the advanceform to show absence details. Until now no problems. I'm able to populate the grid with data through a SQLDataSource. This grid records must be editable and there is where the problems start as I can't figure how to access the RadGrid (RadGrid3) update line that is nested in the AdvancedEditTemplate. In this radgrid I must have a UploadFile control to save an attachment (to filesystem) and a textbox to update a "Reason" property. I need to update this record in the absence table through an SQLDataSource which will call an SP to update these two collumns (attachment link and reason). For this I'm using the Grids UpdateCommand
event as shown below:


CodeBehind:
protected void RadGrid3_UpdateCommand(object sender, GridCommandEventArgs e)
        {
            //Insert Record in Portal Absence Tables for a Update Action
            //Properties: Reason, Attachment, Action(UPDATE),Status(1)
            GridEditableItem editedItem = e.Item as GridEditableItem;
            

            Session["lResourceAbsenceDetailID"] = editedItem["lResourceAbsenceDetailID"].Text;
            Session["Reason"] = "";
            Session["Status"] = 1;
            Session["Action"] = "UPDATE";
            Session["Attachment"] = attachment;
            SqlDataSource5.Select(DataSourceSelectArguments.Empty);
        }




ASPNET COde:

....but it's not working as I can't get the Grid row that I'm updating through (editedItem["lResourceAbsenceDetailID"].Text;). Another problem is that I'm not able to debug this. Can someone please tell me what I must do to make this work. I would very much apreciate any help.

Cheers,
Pedro

Hi Pedro,

It might be easier to use the Advanced Templates demo for this case. Also, this code library project might be helpful - Upload in RadScheduler.


All the best,

Hi Peter,

First of all thank you for your help.

I would have no problem using the advanced templates, but  how can I have  a RadGrid inside an advance template?

Cheers,
Pedro

Hello pedro,

Have you seen this step-by-step tutorial on how to customize the advanced form? Also, you can review the kb articles on how to integrate with the advanced form:

RadEditor
http://www.telerik.com/support/kb/aspnet-ajax/scheduler/integrating-radeditor-in-the-advanced-form-of-radscheduler.aspx

RadComboBox
http://www.telerik.com/support/kb/aspnet-ajax/scheduler/implement-related-radcombobox-controls-in-the-advanced-form.aspx

You will notice that the approach is essentially the same.


Kind regards,

Hello,

I finally decided to buy your components all of them. They really are that good I guess. I just have been strugling about this problem.

I followed your advice and I managed to create a user control for the EditAdvanceForm and InsertAdvanceForm (notice that my solution is built on top of DotNetNuke). It works almost fine. The Scheduler opens the EditAdvanceForm and displays what I want the grid a and some other controls where in between is  RadFileUpload.

My objective is to update two collumns of that grid a normal text collumn (reason) and a file attachment collumn (Attachment). At first I tried to do this through the edit/inset form of the RadGrid. Then I tried to put the RadFileUpload outside the grid. But none of the aproaches works. I then found out that RadFileUpload or FileUpload controls cannot be ajaxified and I saw an example. But this example is very complex (121128_uploadscheduler) so that I would need to create arround 10 user controls just to implement this little feature. Is there a simpler way of solving my problem even if I need to cheat to achieve my goal. I'll attach my two projects The one that contains the Scheduler and the one that contains AdvanceEditForm. It seems like a waste to have 2 project but since we're talking DNN here it has been the only way I was able to make it work. I really apreciate your help and ask you to solve my problem as fast as you can since I need to have this implemented until tomorrow by the end of the day.

Here are the files link: http://rapidshare.com/files/399104827/DNN_AbsenceManagementModules.rar.html

The impotant user controls are the ones that star with View... There are a lot more user controls since DNN is built to work with tipically 3 usercontrols per module (view, edit and settings).

Thank you,
Pedro

Hi pedro,

We noticed that you wrap RadScheduler in RadAjaxPanel. In this case, we recommend you use RadAsyncUpload instead of RadUpload. With RadAsyncUpload, you will not need to make a real postback to upload files. Please, try this and let us know how it goes.


Best wishes,
