This is my coding that I am using to update a row of data on the datagrid and to save that data to sql. Yesterday this coding worked but now im getting this error and I dont know what is wrong.

C#

try
            {

                SqlCommandBuilder local_SqlCommandBuilder = new SqlCommandBuilder(da);

                local_SqlCommandBuilder.ConflictOption = System.Data.ConflictOption.OverwriteChanges;

                da.UpdateCommand = local_SqlCommandBuilder.GetUpdateCommand();

                DataView dv = DGAdmin.ItemsSource as DataView;
                DataTable dtn = dv.Table;
                
                da.Update(dtn);

                dt.AcceptChanges();

            }
            catch (Exception)
            {

                throw;
            }

The Error that I am getting is: The DataAdapter.SelectCommand property needs to be initialized.

how you create da? is there primary key to your table?

Sorry I am still new to this, the GetSelectCommand(); shows an error does not contain definition. I have checked my using directives, is it wpf code or windows forms?

how you create data adapter? you need to give select command as parameter

i think..
SqlDataAdapter da=new SqlDataAdapter(sqlCommand);

You may need to provide command, command type, connection etc for a dataadapter. Did you do that?

Dear RenaldoGG,

What you provide is I think only an update method, where is the Method to collect / get data from Database. You need a method for collecting data and Select command for the DA is located in that. Please check it.
