Command buttons in ASPxGridView do not support tooltips. This example demonstrates how to emulate command buttons or custom buttons with HTML elements and provide tooltips for them (attribute title
).
<dx:GridViewDataTextColumn Name="Command" Caption="#" VisibleIndex="0">
<DataItemTemplate>
<a href = "javascript:grid.AddNewRow();" title="Add new row">New</a>
<a href = "javascript:grid.StartEditRow('<%#Container.VisibleIndex%>');" title="Start edit row '<%#Container.VisibleIndex%>'">Edit</a>
<a href = "javascript:grid.DeleteRow('<%#Container.VisibleIndex%>');" title="Delete row '<%#Container.VisibleIndex%>'">Delete</a>
<a href = "javascript: alert ('This is the custom button');" title="Custom action">Custom action</a>
</DataItemTemplate>
</dx:GridViewDataTextColumn>
