Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

Problem with getting extra data in column of gridview


I have created a gridview based on an SQL Datasource.  The grid view contains several columns(fields) one of which is called "Amount".  In the footer of the gridview their is a field that contains the sum of all of the values contained in the "Amount" field.

By problem is that in instead of getting the value of the Amount displayed in the "Amount" field of each row, I am getting a '0' (Example: 0 25.78 when I should just be getting 25.78.  There is a space between the '0' and the '25.78'.

Code is as follows:


<asp:TemplateField HeaderText="Amount" SortExpression="Amount">

How to Format Data inside a Bound Column of Gridview?



I have a bound column.

<asp:BoundField DataField="WorkPreference"  HeaderText="WorkPreference"
                    <HeaderStyle HorizontalAlign="Left" />

dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data  to a DataRow)

The example of the data which gets bound to this column is like the following:

Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;

What I want is that the data should be presented to the user like the following:

Communications and Marketing Officers

Environmental Assessors

Geologists and Geosciences

Geospatial/Spatial Information Officers

In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview.

It looks like simple but if you can let me know. Thanks.
