cell with a null value returns ' '

[Neelima]

When I try to retrive a cell value, its returning ' ' if the value is null. Is something wrong in the code?
why doesn't it just return empty string('') instead of ' '?

Thank you
Neelima

Dim row As GridDataItem = RadgridDestination.Items(RadgridDestination.SelectedIndexes(0))

btnUpdate.Visible = True

btnAdd.Visible = False

With uc_Addr  ' uc_Addr is an User Control

.Desc = row("Description").Text

.Addr1 = row("Address1").Text

.Addr2 = row("Address2").Text  'retuns ' ' if the cell value is null.

.State.SelectedValue = row("StateID").Text

.City.SelectedValue = row("CityID").Text

.Zip.SelectedValue = row("ZipID").Text

.Phone = row("Phone").Text  'retuns ' ' if the cell value is null.

Hello Neelima,

We insert these tags as a workaround to a well-known bug in IE.  The problem is that if the cells are empty, Internet Explorer 7 hides the borders completely.

Please examine the following links for more information:
IE not rendering borders on empty table cells
Empty cells in HTML tables

You can reproduce the problem with a simple HTML table - just put it in your website and run IE8 in compatibility mode.

Copy Code

<table border="1">
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td></td>
        <td>5</td>
    </tr>
    <tr>
        <td></td>
        <td></td>
        <td>6</td>
    </tr>
</table>
