Oh [big sigh]...found it. Does anyone have any idea why this would fail? I'm sure it was working previously.
<Where>
<IsNotNull>
<FieldRef Name="FileLeafRef"/>
<Value Type="File"></Value>
</IsNotNull>
</Where>

Subject: Validate custom EditorPart field
[cid:image002.png@01CC9A37.C3FBA730]Hi all,
I've taken my image gallery web part to the next level and moved all properties
to an EditorPart class. Everything looks great and works nicely provided all
properties have a value.
I have the following four properties which correspond to the screenshot.
* oListName
* SelectedColumn
* ImgBeginsWith
* AscDesc
However, I want the Filter field (ImgBeginsWith) to be optional, so that all
items are returned when it's empty.
This was working fine before I recreated this property as a TextBox within the
EditorPart section.
ImgFilter = new TextBox();
ImgFilter.TextMode = TextBoxMode.SingleLine;
ImgFilter.Text = string.Empty;
ImgFilter.CssClass = "UserInput";
ImgFilter.ToolTip = "Leave blank to return all images.";
panListSettings.Controls.Add(ImgFilter);
In my web part I then have:
public string _imgBeginsWith = string.Empty;
[WebBrowsable(false),
Personalizable(PersonalizationScope.Shared)]
public string ImgBeginsWith
{
get {
if (_imgBeginsWith == string.Empty)
{
_imgBeginsWith = "";
}
return _imgBeginsWith;
}
set { _imgBeginsWith = value; }
}
And then I check it every way I know how here:
if (ImgBeginsWith != null && SPEncode.HtmlEncode(ImgBeginsWith) != string.Empty
&& !string.IsNullOrEmpty(ImgBeginsWith))
{
oQuery.Query = "<Where><BeginsWith><FieldRef Name=\"FileLeafRef\"/>"
+ "<Value Type=\"File\">" + ImgBeginsWith +
"</Value></BeginsWith></Where>";
}
else
{
oQuery.Query = "<Where><IsNotNull><FieldRef Name=\"FileLeafRef\"/>"
+ "<Value Type=\"File\"></Value></IsNotNull></Where>";
}
Yet it ALWAYS runs the first query option!
Any help please?!?
