Question

if add row to DataTable

row[\"column2\"]=\"column2\";

datatable1.Rows.Add(row);         


        

Answer 1

If anyone wanted to Add DataTable as a source of gridview then--

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("column1"));
dt.Columns.Add(new DataColumn("column2"));

DataRow dr = dt.NewRow();
dr[0] = "column1 Value";
dr[1] = "column2 Value";

dt.Rows.Add(dr);

dataGridView1.DataSource = dt;

Answer 2

here is another way to do such

 private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        dataGridView1.ColumnCount = 3;

        dataGridView1.Columns[0].Name = "Name";
        dataGridView1.Columns[1].Name = "Age";
        dataGridView1.Columns[2].Name = "City";

        dataGridView1.Rows.Add("kathir", "25", "salem");
        dataGridView1.Rows.Add("vino", "24", "attur");
        dataGridView1.Rows.Add("maruthi", "26", "dharmapuri");
        dataGridView1.Rows.Add("arun", "27", "chennai"); 
    }

Answer 3

If you need to manipulate anything aside from the Cell Value string such as adding a Tag, try this:

DataGridViewRow newRow = (DataGridViewRow)mappingDataGridView.RowTemplate.Clone();
newRow.CreateCells(mappingDataGridView);

newRow.Cells[0].Value = mapping.Key;
newRow.Cells[1].Value = ((BusinessObject)mapping.Value).Name;
newRow.Cells[1].Tag = mapping.Value;

mappingDataGridView.Rows.Add(newRow);

Answer 4

Like this:

 dataGridView1.Columns[0].Name = "column2";
 dataGridView1.Columns[1].Name = "column6";

 string[] row1 = new string[] { "column2 value", "column6 value" };
 dataGridView1.Rows.Add(row1);

Or you need to set there values individually use the propery .Rows(), like this:

 dataGridView1.Rows[1].Cells[0].Value = "cell value";

Answer 5

This is how I add a row if the dgrview is empty: (myDataGridView has two columns in my example)

DataGridViewRow row = new DataGridViewRow();
row.CreateCells(myDataGridView);

row.Cells[0].Value = "some value";
row.Cells[1].Value = "next columns value";

myDataGridView.Rows.Add(row);

According to docs: "CreateCells() clears the existing cells and sets their template according to the supplied DataGridView template".

Answer 6

yourDGV.Rows.Add(column1,column2...columnx); //add a row to a dataGridview
yourDGV.Rows[rowindex].Cells[Cell/Columnindex].value = yourvalue; //edit the value

you can also create a new row and then add it to the DataGridView like this:

DataGridViewRow row = new DataGridViewRow();
row.Cells[Cell/Columnindex].Value = yourvalue;
yourDGV.Rows.Add(row);
