GridEditFormItem item = e.Item as GridEditFormItem;

GridDataItem dataitem = e.Item as GridDataItem;

TextBox Notedesc = editedItem.FindControl("txtNoteDesc") as TextBox;

GridView gvNotes = (editedItem.FindControl("gvNotes") as GridView);

string OrdID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["orderId"].ToString();

TextBox Notedescd = (TextBox)dataitem.NamingContainer.FindControl("txtNoteDesc") as TextBox;

Hello Babu,

Could you please try getting the txtNoteDesc, ddlNoteType and gvNotes controls with the following code snippet and let me know if the issue still persists:

if (e.CommandName == "AddNote")

{

clsTaskUpdates_BL objBL = new clsTaskUpdates_BL();

string strName = Session["UserName"].ToString();

GridEditableItem editedItem = e.Item as GridEditableItem;

GridEditFormItem item = e.Item as GridEditFormItem;

GridDataItem dataitem = e.Item as GridDataItem;

TextBox Notedesc = editedItem.FindControl("RadPageView2").FindControl("txtNoteDesc") as TextBox;

GridView gvNotes = (editedItem.FindControl("RadPageView2").FindControl("gvNotes") as GridView);

string OrdID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["orderId"].ToString();

TextBox Notedescd = (TextBox)dataitem.NamingContainer.FindControl("txtNoteDesc") as TextBox;

string NoteDesc = (editedItem.NamingContainer.FindControl("txtNoteDesc") as TextBox).Text;

string NoteType = (editedItem.FindControl("RadPageView2").FindControl("ddlNoteType") as DropDownList).Text;

}

I hope this helps.

Hi Radosla,

Sorry for my delay. I tried your way I am getting following error. see image.

this is what i wrote

string Notedescd = (editedItem.FindControl("RadPageView2").FindControl("txtNoteDesc") as TextBox).Text;

I also tried this way....

TextBox Notedescd = editedItem.FindControl("RadPageView2").FindControl("txtNoteDesc") as TextBox;
