If I use more than one text column with the property "HeightEditableColumn" the file type validation failed.
The result is, that in the last textbox with the "HeightEditableColumn" property the code "</anthemarea></td></tr><tr class="wgrow"><td align="left" valign="middle" class="wgrow " style="width: 120px" " is contained.
The HTML Code is:
<td class="wgrow" valign="middle" colspan="4">
<textarea id="ctl00_ContentPlaceHolderMain_wgPackets_6_ShippingDescription" class="wgeditfield" name="ctl00_ContentPlaceHolderMain_wgPackets_6_ShippingDescription" style="width: 400px; height: 50px;" onblur="isChanged(this,'LightSteelBlue');" cols="1" rows="1"></anthemarea></td>
That only happens, if I try to upload a not valid file type. If the file field is empty it works correct.
If I remove all "HeightEditableColumn" properties (one is ok too) it works fine too.
Thanks
