Remarks

Use the NavigateUrl property to specify the URL to link to when a hyperlink in the column is clicked.

Note

When this property is set, all hyperlinks in the column share the same URL link.

To provide a separate URL for each hyperlink in the column, use the DataNavigateUrlField property.

Note

The DataNavigateUrlField and NavigateUrl properties cannot both be set at the same time. If both properties are set, the DataNavigateUrlField property takes precedence.
