DetailsViewRowCollection.GetEnumerator Method

Returns an enumerator that contains all DetailsViewRow objects in the DetailsViewRowCollection object.

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

public IEnumerator GetEnumerator()

Return Value

Type: System.Collections.IEnumerator
An IEnumerator-implemented object that contains all DetailsViewRow objects in the DetailsViewRowCollection.



Use this method to get an enumerator that can be iterated through linearly to access each item in the DetailsViewRowCollection object. To access the item at the current position in the enumerator, use the Current property. Use the MoveNext method to move to the next item in the collection. To move the enumerator to its initial position, use the Reset method.


When you initially get the enumerator or use the Reset method to move the enumerator to the first item in the collection, you must call the MoveNext method. Otherwise, the item represented by the Current property is undefined.

The following code example demonstrates how to use the GetEnumerator method to retrieve an enumerator that contains the items from the collection. The enumerator is then iterated through and the value of each row is displayed on the page.

  void SubmitButton_Click(Object sender, EventArgs e)

    // Use the Count property to determine whether the 
    // Rows collection contains any item. 
    if (ItemDetailsView.Rows.Count > 0)

      MessageLabel.Text = "The row values are: <br/><br/>";

      // Get the enumerator that contains the data rows in the  
      // DetailsView control.
      IEnumerator rowEnumerator = ItemDetailsView.Rows.GetEnumerator();

      // Iterate though the enumerator and display the field values. 
      while (rowEnumerator.MoveNext())
        DetailsViewRow row = (DetailsViewRow)rowEnumerator.Current;

        // Use the Text property to access the value of  
        // each cell. In this example, the cells in the  
        // first column (index 0) contains the field names,  
        // while the cells in the second column (index 1) 
        // contains the field value. 
        MessageLabel.Text += row.Cells[0].Text + " = " +
          row.Cells[1].Text + "<br/>";

      MessageLabel.Text = "No items.";
