How to save data from dynamically column [telerik gridview] [need help]

[desuke]

Hi all,
I've some problem (I weakness in english language but I'll try to explain.)  
Firstly, I've created dynamically column from telerik gridview but I couldn't save new data to datatable

About telerik gridview that I try to this code 

 void grid_UpdateCommand(object source, GridCommandEventArgs e)

    {

        Hashtable newValues = new Hashtable();

        GridEditableItem item = e.Item as GridEditableItem;

        item.OwnerTableView.ExtractValuesFromItem(newValues, item);

        Response.Write("Updated Name: " + newValues["ContactName"].ToString());

    }

 void grid_UpdateCommand(object source, GridCommandEventArgs e)

    {

        Hashtable newValues = new Hashtable();

        GridEditableItem item = e.Item as GridEditableItem;

        item.OwnerTableView.ExtractValuesFromItem(newValues, item);

        Response.Write("Updated Name: " + newValues["ContactName"].ToString());

    }

 void grid_UpdateCommand(object source, GridCommandEventArgs e)

    {

        Hashtable newValues = new Hashtable();

        GridEditableItem item = e.Item as GridEditableItem;

        item.OwnerTableView.ExtractValuesFromItem(newValues, item);

        Response.Write("Updated Name: " + newValues["ContactName"].ToString());

    }

void grid_UpdateCommand(object source, GridCommandEventArgs e)
   {
       Hashtable newValues = new Hashtable();
       GridEditableItem item = e.Item as GridEditableItem;
       item.OwnerTableView.ExtractValuesFromItem(newValues, item);
       Response.Write("Updated Name: " + newValues["ContactName"].ToString());

   }

this code is perform to gather new value (when you key in new value in editable textbox),In runtime mode will through to   grid_UpdateCommand method. that's ok  (I can show new value )

But my purpose want to loop all new value (when you key in new value) into my Data-table 
as following 

Hashtable newValues = new Hashtable();
            foreach (GridEditableItem Item in grid.MasterTableView.Items)
            {

                Item.OwnerTableView.ExtractValuesFromItem(newValues, (GridEditableItem)Item);
                string str = newValues[0].ToString();
            }

But I couldn't  get new value when I loop from grid (I couldn't use ExtractValuesFromItem method it displayed error message as "Unable to cast object of type 'MyItemTemplate' to type 'System.Web.UI.IBindableTemplate'."

How should I do this problem ? 

Thanking in advance

Hello Bhadhai,

Note that the RadGrid.MasterTableView.Items collection contains GridDataItems and not the items that are in edit mode. To get a reference to the currently edited items, you should use the RadGrid.EditItems collection instead. For more information on the matter, I would suggest that you review the following help article (pay special attention to the "Using the EditItems collection" section):

Edit forms

I hope this helps.
