C# 2005 - DataGridView and ComboBoxes questions

[jcrcarmo]

Hello everyone,

 

I have a DataGridView in a windows form with three columns:

 

Column1 is TipoComboBoxColumn

Column2 is QuantidadeColumn

Column3 is SementeComboBoxColumn

 

I need the SementeComboBoxColumn to display values according to the value I select in the TipoComboBoxColumn.

 

How do I go about accomplishing that? The code below works in part, BUT when I'm editing the value of SementeComboBoxColumn, the other values for the other rows in this column disappear. This is driving nuts!

 

 

       private void tabBAdetDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
       {
           if (tabBAdetDataGridView.Columns[e.ColumnIndex].Name == "EspecieComboBoxColumn")
           {
               this.tabSementesTableAdapter.FillByTipo(this.sascrDataSet.tabSementes, tabBAdetDataGridView.Rows[e.RowIndex].Cells["TipoComboBoxColumn"].Value.ToString());
               this.EspecieComboBoxColumn.DataSource = this.tabSementesBindingSource;
               this.EspecieComboBoxColumn.DisplayMember = "Semente";
           }
           else
           {
               this.tabSementesTableAdapter.Fill(this.sascrDataSet.tabSementes);
               this.EspecieComboBoxColumn.DataSource = this.tabSementesBindingSource;
               this.EspecieComboBoxColumn.DisplayMember = "Semente";
           }
       }

 

 

Thanks in advance,

Try using a dataset and fetching a row from it, when a row is selected then bind each value to its appropriate combo box.
