Accessing values of fields in the InsertItemTemplate

[James]

I am attempting to use the manual CRUD processing of data in my RadGrid via the DataForm.  I am using .net 4.5 and Visual Studo 2013, language VB.net. For the insert, I am able to display the insert form and enter data, the question I have is how to retrieve the entered values from the form in the code behind.  I want to interrogate the entered values and take some additional action before using a SQL stored procedure to insert the data.  The code from the _ItemInserting routine is:

        Dim sCatName as string
        Dim insertedItem As RadDataFormEditableItem = TryCast(e.DataFormItem, RadDataFormEditableItem)
        Dim newValues As New Hashtable()

        insertedItem.ExtractValues(newValues)

        For Each entry As DictionaryEntry In newValues

            sCatName = entry.Value

        Next

In this case the entry.value is NULL.

How do I get to the data?

Thanks

Hi James,

If you would like to perform manual CRUD operations wit RadDataForm try to follow the same approach as the one illustrated in the following article.

• RadDataForm Manual CRUD Operations

In case the behavior persists please make a sample runnable project where the issue is replicated and send it in a support ticket. This way we would be able to investigate the issue locally and look for its cause.

I will put together a project and submit it.  The hash table of extracted values is null

Samething happen to me.

Im using c#.

protected void RadDataForm1_ItemInserting(object sender, RadDataFormCommandEventArgs e)
   {

       RadDataFormEditableItem insertedItem = e.DataFormItem as RadDataFormEditableItem;
       Hashtable newValues = new Hashtable();
       insertedItem.ExtractValues(newValues);

       RopackNews.DataModel.NewsData test = new RopackNews.DataModel.NewsData();
       test.Createur = newValues["Createur"].ToString();
       test.DateCreation = DateTime.Now;

       using (RopackNewsEntities context = new RopackNewsEntities())
       {
           context.NewsData.Add(test);
       }

   }

   protected void Test2_FileUploaded(object sender, FileUploadedEventArgs e)
   {
       RadDataFormEditableItem editItem = ((Telerik.Web.UI.RadWebControl)(sender)).NamingContainer as RadDataFormEditableItem;
       RadBinaryImage bImg = editItem.FindControl("RadBinaryImage1") as RadBinaryImage;
       byte[] image;
       long fileLength = e.File.InputStream.Length;
       image = new byte[fileLength];
       e.File.InputStream.Read(image, 0, image.Length);
       bImg.DataValue = image;
   }

   public IQueryable<NewsData> SelMethod()
   {
       if (RadGrid1.SelectedValue != null)
       {
           int column2 = (int)RadGrid1.SelectedValue;

           var newsSelected = from p in context.NewsData
                              where p.ID == column2
                              orderby p.ID
                              select p;
           return newsSelected;
       }
       return null;
   }


   protected void RadDataForm1_NeedDataSource(object sender, RadDataFormNeedDataSourceEventArgs e)
   {
       RadDataForm1.DataSource = SelMethod();
   }

   protected void RadDataForm1_PreRender(object sender, EventArgs e)
   {
       RadDataForm1.Rebind();
   }

Sorry, I can't edit my own post. It crash because the newValues is null.
(don't bother about the FileUploaded, it's some old code)

I used one of your scenario and copy pasted the code to ry out the manual CRUD...
Same as James.

Dim insertedItem As RadDataFormEditableItem = TryCast(e.DataFormItem, RadDataFormEditableItem)

I switched RadDataFormEditableItem to RadDataFormInsertItem and evrything works fine now.
