I'm trying to bind to a dataset, but am getting an exception that a field does not exist, which should. My method to create the DataSet is below (in its infancy). It's VERY simple. Here is the databinding:
DataSet result = this.getDataSet(fields);
dataGridView1.DataSource = result.Tables["main"];
cbc0 = new DataGridViewComboBoxColumn
cbc0.DisplayIndex = 0;
cbc0.DataSource = result.Tables["createOptio
cbc0.DisplayMember = "text"; //////////////////////////
cbc0.ValueMember = "id";
dataGridView1.Columns.Add(
DataSet creation code:
private DataSet getDataSet(ComboBox cb) {
DataSet result = new DataSet();
DataTable dt = new DataTable("main");
DataColumn dc = new DataColumn("AttributeName"
dt.Columns.Add(dc);
dc = new DataColumn("dbField", Type.GetType("System.Strin
dt.Columns.Add(dc);
dc = new DataColumn("create", Type.GetType("System.Int32
dt.Columns.Add(dc);
DataRow row;
for (int i = 0; i < cb.Items.Count; i++) {
row = dt.NewRow();
cb.SelectedIndex = i;
row["AttributeName"] = cb.SelectedValue.ToString(
row["dbField"] = cb.SelectedValue.ToString(
row["create"] = 0;
dt.Rows.Add(row);
}
result.Tables.Add(dt);
dt = new DataTable("createOptions")
dc = new DataColumn("id", Type.GetType("System.Int32
dt.Columns.Add(dc);
dc = new DataColumn("text", Type.GetType("System.Strin
dt.Columns.Add(dc);
row = dt.NewRow();
row["id"] = 0;
row["text"] = "Create";
dt.Rows.Add(row);
row = dt.NewRow();
row["id"] = 1;
row["text"] = "Don't Create";
dt.Rows.Add(row);
result.Tables.Add(dt);
return result;
}

Hello, I tried to run your code using a databound combobox as the parameter in the DataSet result = this.getDataSet(fields);
and it compiled an ran without errors...So I'm not sure what the problem is...
I can give you one general tip, always set DisplayMember and ValueMember before you set DataSource
