Change FileName of Upload and save

[Karl]

Hi,

I'm using AsyncUpload in a RadGrid

 

<

 

FormTemplate>.

 

 

 

 

When the User makes the changes to the record I want to Change the filename when it uploads it. The below works for the first row in the radgrid. When I try to update the second row  I get object reference not set to an instance of an object.

Am i missing something?

Thanks

string filenamenew = string.Empty;


            GridEditFormItem editedItem = (GridEditFormItem)(gvContractors.MasterTableView.GetItems(GridItemType.EditFormItem)[0]);
            RadTextBox txtcustomername = (RadTextBox)editedItem.FindControl("txtcustomername");
            filenamenew = txtcustomername.Text.Replace(" ", "_");


        e.File.SaveAs(System.Configuration.ConfigurationManager.AppSettings["ContractorDatabaseUploads"] + filenamenew + "_Certificate" + e.File.GetExtension());

Hi Karl,

You code looks correct. On which line do you receive the exception. Can you paste here the stack-trace so that we can take a look at it?

Hi,
The attached is all I get, I can't view the stacktrace. I have an email function that sends emails when the

 

 

void Application_Error(object sender, EventArgs e)

 

{

}
is hit, and nothing is fired. This works on everthing else

Any ideas?

Hi,


Is this there anything else I can do to get this to work?

Thanks

Hello Karl,

You can obtain a full stack-trace if you temporarily disable the AJAX updates on the page.

If you're using RadAjaxManager set EnableAJAX to "false".

In case you're using update panels set EnablePartialRendering on the ScriptManager to "false":

<asp:ScriptManager ID="RadScriptManager1" runat="server" EnablePartialRendering="false">
</asp:ScriptManager>

We should be able to help with the full stack trace at hand.

You should also be aware that there's a known issue with the RadAsyncUpload in the official Q2 release. Our recommendation is to update to internal build 2010.2.722 before continuing.

I hope this helps.

Thanks, this is what I get:

In which event do you access the RadTextBox? I suppose that FindControl returns null instead of RadTextBox hence the exception. Here is an alternative approach:

void Grid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            string filenamenew = string.Empty;

            RadTextBox txtcustomername = (RadTextBox)editedItem.FindControl("txtcustomername");
            filenamenew = txtcustomername.Text.Replace(" ", "_");


            e.File.SaveAs(System.Configuration.ConfigurationManager.AppSettings["ContractorDatabaseUploads"] + filenamenew + "_Certificate" + e.File.GetExtension());
        }
    }

[Karl]

This is what I have,

protected void RadAsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
{
    string filenamenew = string.Empty;

        GridEditFormItem editedItem = (GridEditFormItem)(gvContractors.MasterTableView.GetItems(GridItemType.EditFormItem)[0]);
        RadTextBox txtcustomername = (RadTextBox)editedItem.FindControl("txtcustomername");
        filenamenew = txtcustomername.Text.Replace(" ", "_");


    e.File.SaveAs(System.Configuration.ConfigurationManager.AppSettings["ContractorDatabaseUploads"] + filenamenew + "_Certificate" + e.File.GetExtension());
}

I tried the way you suggested but  it comes up with e.File does not exist which makes sense as e.File exists on the _FileUploaded Event.

Thanks

I believe that this is issue with RadGrid. I am not sure if it is possible to access controls that are in edit form outside of the Grid context.

[Karl]

Any ideas on how I can achieve what I want?

[Tojara]

If I were you, I would use the RadAsyncUpload.UploadedFiles collection. You can use it to access the uploaded files outside of the FileUploaded event. First file in the collection is from the first input, second from the second and so on. You can it inside the ItemCommand event of RadGrid.

[Karl]

Thanks, that worked. If any one else is interested :
used this sample and post for ref :
http://www.telerik.com/community/forums/aspnet-ajax/upload/radasyncupload-not-to-save-to-file-location.aspx

    IList<UploadedFile> files;

    protected void Page_Load(object sender, EventArgs e)
    {
        files = new List<UploadedFile>();
    }
    protected void RadAsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
    {
        files.Add(e.File);
    }

//Add this in your Update and Insert
      foreach(UploadedFile test in files)
        {
            test.SaveAs(System.Configuration.ConfigurationManager.AppSettings["MyPath"] + filenamenew + "_Certificate" + test.GetExtension().ToString());
        }
