Hello,
Can someone please tell me the custom code in vb.net to hide or show an image based on weather a field is null or has a value.
For example: If the field value is Null, then I do not want to see the image. If the field has any value in it ,I want to see the image.
Thanks

Hi Shawn
You could try the following code in the BeforeShow event of Image control
For the Record form
<FormName><ControlName>.Visible = Not IsNothing(Item.ControlName.Value)
For the Grid, EditableGrid
<FormName><ControlName>.Visible = Not IsNothing(DataItem.ControlName.Value)

Checkmark the Image's "Extended HTML" property, to give the image a Visible
property that can be set True or False. Until it's "extended", this
property is not available and you can't hide it.

Hi Stan,
The code you suggested worked great, however now the actual image does not show. What does show is a broken image tag. So if there is something in the field I get the broken image tag and if there is nothing in the field it is blank.
This is VERY close to what I need. I just need to know what I am doing wrong. Here is my BeforeShow code:
L_MA11_Main_Data_tblLocation.Visible = Not IsNothing(DataItem.Location.Value)
Not sure if this helps, but here is the html:
<td class="LightWalkDataTD">
<p align="center"><a class="LightWalkDataLink" href="{Location}"><img class="LightWalkInput" src="icon_search.gif" border="0"></a></p>
</td>
Any ideas?
