getting a child to update after a record add

[Joe]

Hello;

I have run out of ideas!

I have a simple parent/child databound grid.

The parent has a list of people, the child has a list of stores assigned to them.

I am wanting so that if I want to assign a new store they can click on "click here to add a new row" then have it work.

The attached picture should help.

In "Cust Stop No" they should be able to type in a number, then I want to do some validation to make sure it is a valid store ID.

If it is, i want to fill in the other columns of data.

I populate the grid here:

private void button1_Click(object sender, EventArgs e)
       {
           radGridView1.DataSource = null;

           rep_assigned_stop_matrixTableAdapter.FillByStopDetails(first_choice_mainDataSet.rep_assigned_stop_matrix);

           GridViewRelation relation = new GridViewRelation(radGridView1.MasterTemplate);
           relation.ChildTemplate = childTemplate;
           relation.RelationName = "repStopRelationship";
           relation.ParentColumnNames.Add("id");
           relation.ChildColumnNames.Add("rep_id");
           radGridView1.Relations.Add(relation);
           radGridView1.DataSource = first_choice_mainDataSet.rep_info;

           //radGridView1.AutoGenerateHierarchy = true;
           radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

       }

Then I have tried to catch the cell change event here:

private void radGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
     {

         IEditableObject editbaleObject = e.Row.DataBoundItem as IEditableObject;


         DataRowView dataRowView = e.Row.DataBoundItem as DataRowView;
         var rowIndex = e.Row.Index;
         if (rowIndex == -1)
         {
             radGridView1.Rows[1].Cells["stop_name"].Value = "cityname";

         }

 

I am several hours in and not making any headway....please help!

Thank you,

 

Joe

Hi Joe,

Thank you for writing.

In this case it would be better to use the UserAddedRow/UserAddingRow events which are fired when the user adds the new row, and you can directly set the cell value if needed:

void radGridView1_UserAddedRow(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[1].Value = "test";
}

In addition, you can use the DefaultValuesNeeded event to add default values. Detailed information is available here: New Row.

Let me know if you have additional questions.

I read that yesterday and tried it - repeatedly.  It did not work.  Today it works.  I have no idea what I was doing wrong  but it had to be something simple.  Thank you and the documentation was complete and correct.
