Can you add data to a datagrid with no data source?

Question

I have a DataGrid with 5 template columns,

However when I try and add some dynamically created controls into the grid, it fails, as there are no rows.

-Can i add a blank row in and use that? and how? -Or any other way?

Answer 1

I'm pretty sure you have to bind to a data source. But it's easy enough to create your own DataTable and insert a row into it with some dummy info.

//pseudo code:

DataTable dt = new DataTable();
DataColumn dc = new DataColumn("column1");

DataRow dr = dt.NewRow();
dr["column1"] = "value1";
dt.Rows.AddNew(dr);

myDataGrid.DataSource = dt;
myDataGrid.DataBind();

If you are using an unbound DataGridView, you can create new rows and then add them to DataGridView. Your question referred to DataGrid, but you tagged it for DataGridView.

// Sample code to add a new row to an unbound DataGridView
DataGridViewRow YourNewRow = new DataGridViewRow();

YourNewRow.CreateCells(YourDataGridView);
YourNewRow.Cells[0].Value = "Some value"
YourNewRow.Cells[1].Value = "Another value";

YourDataGridView.Rows.Add(YourNewRow);
