How to set CssClass on button in DataGrid

I have a ButtonColumn in a DataGrid:

<asp:ButtonColumn HeaderText="Edit" ButtonType="PushButton" Text="Edit" />

How do I set it's CSS class?

The only way I can see to do it, is hooking to the RowDataBound event:

Protected Sub dgSchedule_ItemDataBound(sender As Object, e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgSchedule.ItemDataBound
    If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then
        DirectCast(e.Item.Cells(6).Controls(0), Button).CssClass = "confirmButton"

    End If
End Sub

I just feel like there must be a neater way. What happens if I add/remove columns, I'll have to come back here and remember to change column 6...

I tried using a TemplateColumn and a usual asp:Button - This worked, but then clicking it did not fire the ItemCommand event of the gr开发者_JAVA百科id which I need to fire.

I have resolved this by using a GridView instead of a DataGrid. Actually not sure why I used a DataGrid in the first place.

This gives an additional property ControlStyle-CssClass

e.g.

<asp:ButtonField HeaderText="Edit" ButtonType="Button" Text="Edit" ControlStyle-CssClass="confirmButton" />

You've got two options:

1. You can set the CssClass property of the ButtonColumn:

<asp:ButtonColumn CssClass="myStyle" ...></asp:ButtonColumn>

This will render the following HTML:

<td class="myStyle">
    <input type=button name=select ...>
</td>

As you can see, the CSS class is actually applied to the containing element. To style the column, do this:

.myClass
{
   /*Your style attributes go here*/
}

And to style the actual button, do this in your CSS:

.myClass INPUT
{
   /*Your style attributes go here*/
}

2. Alternatively, you can use a TemplateColumn instead of a ButtonColumn and set the CssClass property of the nested button control:

<asp:TemplateColumn HeaderText="Delete">
    <ItemTemplate>
        <asp:Button ID="DeleteButton" runat=server Text="Delete" CssClass="myClass" CommandName="Delete" />
    </ItemTemplate>
</asp:TemplateColumn>

The CSS for this is just as you would expect:

.myClass
{
   /*Your style attributes go here*/
}

If you need to stick with DataGrid rather than use GridView, one way to solve this problem is to setup an OnItemDataBound event.

OnItemDataBound="mydatagrid_ItemDataBound"

Then in the code behind you can attached the CSS class to the button as follows:

//ON DATA BIND
protected void mydatagrid_ItemDataBound(object sender, DataGridItemEventArgs e)
    if (e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer) {
        Button myButton= (Button)e.Item.Cells[5].Controls[0];
        myButton.Attributes["class"] = "buttonClass";   
    }
}
