Adding and Inserting Rows

When RadGridView is in unbound mode, you can add new rows to the Rows collection.

Adding rows to RadGridView

For example, if the grid control contains four columns – GridViewTextBoxColumn, GridViewDecimalColumn, GridViewDateTimeColumn and GridViewCheckBoxColumn you can add an empty row as it is demonstrated in the code snippet below.

The RadGridView.Rows.AddNew() method adds an empty row and allows the user to enter a value for each column cells’:

The RadGridView.Rows.Add(value-for-first-column, value-for-second-column, value-for-third-column) method adds a new row with the specified values. You can use the following code snippet to add values for each column:

Add a new row with values

radGridView1.Rows.Add("Adding New Row", 12.5, DateTime.Now, true);

RadGridView1.Rows.Add("Adding New Row", 12.5, DateTime.Now, True)

You can also add rows by creating an instance of GridViewDataRowInfo and adding it to the Rows collection of RadGridView:

Add a GridViewDataRowInfo

GridViewDataRowInfo rowInfo = new GridViewDataRowInfo(this.radGridView1.MasterView);
rowInfo.Cells[0].Value = "GridViewDataRowInfo";
rowInfo.Cells[1].Value = 11.4;
rowInfo.Cells[2].Value = DateTime.Now.AddDays(5);
rowInfo.Cells[3].Value = true;

Dim rowInfo As New GridViewDataRowInfo(Me.RadGridView1.MasterView)
rowInfo.Cells(0).Value = "GridViewDataRowInfo"
rowInfo.Cells(1).Value = 11.4
rowInfo.Cells(2).Value = DateTime.Now.AddDays(5)
rowInfo.Cells(3).Value = True

Inserting rows in RadGridView

Rows can be inserted at a specified position by using the Insert method of the Rows collection. Below you can see an example of this functionality:

Insert a GridViewDataRowInfo

GridViewDataRowInfo dataRowInfo = new GridViewDataRowInfo(this.radGridView1.MasterView);
dataRowInfo.Cells[0].Value = "Inserted Row";
dataRowInfo.Cells[1].Value = 1156.54;
dataRowInfo.Cells[2].Value = DateTime.Now.AddDays(14);
radGridView1.Rows.Insert(2, dataRowInfo);

Dim dataRowInfo As New GridViewDataRowInfo(Me.RadGridView1.MasterView)
rowInfo.Cells(0).Value = "Inserted Row"
rowInfo.Cells(1).Value = 1154.54
rowInfo.Cells(2).Value = DateTime.Now.AddDays(14)
RadGridView1.Rows.Insert(2, dataRowInfo)
