Force Update from a filtered DataGridView to Database

Tag: c#,sql-server-2008

I have created an application to fix a date conversion problem when transferring data from the machines. The conversion works great. I create a DataGridView that contains all records. I then sort the DataGridView to display the data that needs updating using SqlDataAdapter and DataSet. I then make the changes to the data in the DataGridView and click a save button to apply changes to the database table.

     try
        {
            MessageBox.Show("Complete");
            this.log5DataGridView.EndEdit();
            //this.log5BindingSource.DataSource = this.log5DataGridView.DataSource; <-- Last Resort
            this.log5BindingSource.ResetBindings(false);
            this.log5BindingSource.EndEdit();
            this.log5TableAdapter.Update(roboticlineDataSet.Log5);
        }
        catch { }

When I run in debug mode the log5DataGridView.DataSource Table[] shows the data changes are available. But the log5BindingSource never seems to get the changes to push it through to the TableAdapter Update. I tried the ResetBindings, EndEdit() the last thing is to take the Datasource and force it to the BindingSource.

If I use the following code to search for the precise record the save / update to database will not occur.

 using (SqlDataAdapter adpt = new SqlDataAdapter("SELECT * FROM [dbo].[RoboticLine] WHERE [FSItemNumber] = '" + Value + "' ORDER BY [FSItemNumber] ASC;", conn))
                        {
                            DataSet ds = new DataSet();
                            adpt.Fill(ds);
                            valueComboBox.Enabled = false;
                            log5DataGridView.DataSource = ds.Tables[0];
                            log5DataGridView.Refresh();
                            this.log5DataGridView.Rows[0].Selected = true;
                        }//end of adpt using

The Question is if there is a way to save the searched log5DataGridView record back to the database as the datagridview table retains the change but the log5BindingSource still contains the original

this.log5TableAdapter.Fill(this.roboticlineDataSet.Log5);

Thank you.

Best How To :

Found out what was occurring, when I programmed the datagridview to show the searched data it did not change the bindingsource but left it the same from the Form Load ().

this.log5TableAdapter.Fill(this.roboticlineDataSet.Log5);

To resolve this I found the RoboticLineTable in the Dataset.xsd location in the Soultion Explorer. Here I selected the roboticlinetableadapter and right-clicked where i selected Add->Query. Here I created a SQL query with a where ID = @Value to do the required filtering / search. This replaces the using SqlDataAdapter code with this code

this.log5DataGridView.EndEdit();
this.log5BindingSource.EndEdit();    
this.log5tableAdapter.FillByID(this.roboticline.Log5, Value);
this.invalidate();
this.log5DatagridView.Refresh();

Now when I wish to save, the BindingSource has the changes made in the datagridview and update / save to the Database. Creating and refilling the tableadapter helps keep the link to the bindingsource for you.

Hope this helps someone else that may run into this in the future

Is it possible to concactenate a DataBound value with a constant string in XAML DataBinding?

You can use a StringFormat in your binding, like so: <TextBox Text="{Binding ItemName, StringFormat={}Item: {0}}"/> That being said, it may cause some unexpected behavior when editing. For example, if the user edits only the item name (excluding the 'Item:' text), then when the TextBox loses focus, the string format will...
