Huge SharePoint 2010 list

I’ve been working on SharePoint 2010 project for my client. The project is simple but requires a lot of manual work. As result, I get the simple custom list. For this list, I created New Form page to make some customization. When I check it in SharePoint designer list was displayed without any problem. But when I uploaded the list into SharePoint site and try to add something list I get a strange error: “Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator. ”

What’s going on?! The solution was simple but required some work to get a result. It seems that SharePoint has a problem with a large XSL transforms  in a single template. As far as I know, the limit is 50 elements. The problem has been sent to Microsoft but it looks that without any result. So what to do? I found a solution at Technet, but for me it’s messy, so please find my version.

When I switch to the code view of my New form I had to find:  <xsl:call-template name=”dvt_1.rowedit”/> element.  Then we have to select it and make a copy and CTRL+V below it. Then you need to add 2 at the need of string. As result you should get <xsl:call-template name=”dvt_1.rowedit2″/> . In my case it was enough, but if your list is bigger it could be necessary to add another element.

Go back to <xsl:call-template name=”dvt_1.rowedit”/> , select it and find matching tag. You should find somewhere at the bottom: </xsl:template> . Good. Now you have to copy below this element:

<xsl:template name="dvt_1.rowedit1">

<xsl:param name="Pos" select="position()"/>

<tr>

<td>

<table border="0" cellspacing="0" width="100%">

</table>

</td>

</tr>

</xsl:template>

And then you need just copy into <table></table> tags some of your rows from space between <xsl:call-template name=”dvt_1.rowedit”/> and </xsl:template> . I have taken half of them. In the result you get something like this

<xsl:template name="dvt_1.rowedit1">
<xsl:param name="Pos" select="position()"/>
<tr>
 <td>
 <table border="0" cellspacing="0" width="100%">
 <tr>
 <td width="190px" valign="top" class="ms-formlabel">
 <H3 class="ms-standardheader">
 <nobr>ID/Status</nobr>
 </H3>
 </td>
 <td width="400px" valign="top" class="ms-formbody">
 <SharePoint:FormField runat="server" id="ff22{$Pos}" ControlMode="New" 
FieldName="ID_x002f_Status" __designer:bind="{ddwrt:DataBind('i',concat('ff22',$Pos),
'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@ID_x002f_Status')}"/>
 <SharePoint:FieldDescription runat="server" id="ff22description{$Pos}" 
FieldName="ID_x002f_Status" ControlMode="New"/>
 </td>
 </tr>
 </table>
 </td>
</tr>
</xsl:template>

When you save changes, you will be able to add a new element without a problem. Do you like this post? You can check my other post about SharePoint development here.
