How to add a new row to datagridview programmatica

Question

if add row to DataTable

DataRow row = datatable1.NewRow();
row["column2"]="column2";
row["column6"]="column6";
datatable1.Rows.Add(row);

How about DataGridView??

Answer 1

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 2

You can do:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "XYZ";
row.Cells[1].Value = 50.2;
yourDataGridView.Rows.Add(row);

or:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);

Another way:

this.dataGridView1.Rows.Add("five", "six", "seven","eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");

Answer 3

If you´ve already defined a DataSource, You can get the DataGridView´s DataSource and cast it as a Datatable.

Then add a new DataRow and set the Fields Values.

Add the new row to the DataTable and Accept the changes.

In C# it would be something like this..

DataTable dataTable = (DataTable)dataGridView.DataSource;
DataRow drToAdd = dataTable.NewRow();

drToAdd["Field1"] = "Value1";
drToAdd["Field2"] = "Value2";

dataTable.Rows.Add(drToAdd);
dataTable.AcceptChanges();

Answer 4

Lets say you have a datagridview that is not bound to a dataset and you want to programmatically populate new rows...

Here's how you do it.

// Create a new row first as it will include the columns you've created at design-time.

int rowId = dataGridView1.Rows.Add();

// Grab the new row!
DataGridViewRow row = dataGridView1.Rows[rowId];

// Add the data
row.Cells["Column1"].Value = "Value1";
row.Cells["Column2"].Value = "Value2";

// And that's it! Quick and painless... :o)

Answer 5

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 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);
