GridViewRow.RowState Property

 

Gets the state of the GridViewRow object.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public virtual DataControlRowState RowState { get; set; }

Property Value

Type: System.Web.UI.WebControls.DataControlRowState

A bitwise combination of the DataControlRowState values.

Use the RowType property to determine the state of the GridViewRow object. The state can be a bitwise combination of the values in the following table:

Status value

Description

DataControlRowState.Alternate

The GridViewRow object is an alternate row in the GridView control.

DataControlRowState.Edit

The GridViewRow object is in edit mode.

DataControlRowState.Normal

The GridViewRow object is in its normal (default) state.

DataControlRowState.Selected

The GridViewRow object is selected.

This property is commonly used to determine the state of a row before performing an operation.

The following example demonstrates how to use the RowState property to determine whether a row is in edit mode or is selected. If the user selects a different row while the GridView control is in edit mode, the GridView control exits edit mode.

    // exit edit mode. This ensures that the GridView control exits edit mode
    // when a user selects a different row while the GridView control is in

      AuthorsGridView.EditIndex = -1;

  void AuthorsGridView_RowEditing(Object sender, GridViewEditEventArgs e)
  {

    // Get the row being edited.
    GridViewRow row = AuthorsGridView.Rows[e.NewEditIndex];

    // Check the row state. If the row is not in edit mode and is selected,
    // select the current row. This ensures that the GridView control selects
    // the current row when the user clicks the Edit button.
    if(row.RowState != (DataControlRowState.Edit|DataControlRowState.Selected))
    {
      AuthorsGridView.SelectedIndex = e.NewEditIndex;
    }
