Adding and Inserting Rows In Unbound Mode
When RadGridView is in unbound mode, you can add new rows to the Rows collection.
Adding a GridViewDataRowInfo to the Rows collection is supported only when RadGridView is in unbound mode. If the grid is data-bound, an InvalidOperationException is thrown with the message: "Rows cannot be programmatically added to the RadGridView's rows collection when the control is data-bound." To add rows in bound mode, add the data item to the underlying data source instead.
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.
public RadForm1()
{
InitializeComponent();
this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
this.radGridView1.Columns.Add(new GridViewTextBoxColumn(){ HeaderText="TextBox Column" });
this.radGridView1.Columns.Add(new GridViewDecimalColumn(){ HeaderText="Decimal Column" });
this.radGridView1.Columns.Add(new GridViewDateTimeColumn(){ HeaderText="DateTime Column" });
this.radGridView1.Columns.Add(new GridViewCheckBoxColumn(){ HeaderText="CheckBox Column" });
}
The RadGridView.Rows.AddNew() method adds an empty row and allows the user to enter a value for each column cells’:
Add an empty row
radGridView1.Rows.AddNew();Figure 1: Add a blank new row
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);Figure 2: Add new row with data in it
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;
radGridView1.Rows.Add(rowInfo);Figure 3: Add new row by creating an instance first
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);Figure 4: Insert row to a specific position
