Question

I have an ASPxGridView on my page which has a few columns of data. Basically what I want to do is to add a tooltip (which I have as a user control) to each of the column headers. I don’t think that it is possible to do this in the markup as I don’t want to loose any of the functionality already in the grid headers (e.g. filter, etc) so what I need to do is loop through the header cells somehow to add the control in dynamically.

I have tried using the OnHtmlRowPrepared event but this does not fire for headers!

I want to achieve something like the following so the tooltip will show on hover (the tooltip is already implemented).

Any ideas?

You can use the GridViewColumn.HeaderCaptionTemplate property to implement this.

Here are two samples on using this property:

1. Using header caption template in aspx
2. Using header caption template in code behind
