How to add rows into a datatable dynamically?
I created some columns with this code:
DataTable obj_dt_grdvw = new DataTable();
obj_dt_grdvw.Columns.Add("_Pur_Product_Id", typeof(string));
obj_dt_grdvw.Columns.Add("Product_pur_Name", typeof(string));
Now I tried to add a row of data but showing error "there is no row at 0"
obj_dt_grdvw.Rows[0]["_Pur_Product_Id"] ="12";
obj_dt_grdvw.Rows[0]["Product_pur_Name"] ="milk";
What is my mistake?
When you create new datatable, it is empty - i.e. there is no rows. That's why you can't find row at index 0. You should create and add rows manually.
Use DataTable.NewRow method to create new row with same columns (i.e. same schema) as your datatable:
DataRow row = obj_dt_grdvw.NewRow(); // create new row
row["_Pur_Product_Id"] ="12"; // set field values
row["Product_pur_Name"] ="milk";
obj_dt_grdvw.Rows.Add(row); // add this new row to table rows
