Recommendations for maintaining Infopath performance

No comments  
I'm creating an InfoPath form that is a bit large and starting to lag so I decided to look up better practices for developing InfoPath forms to maintain performance. Here is what I found online:
- Keep views from being too large or complex. Split large views into several smaller ones with buttons to switch between them.
- Avoid lots of tables (data or layout) in any single view.
- Use Master/Detail to reduce the number of controls in one page, whenever possible.
- Try to use filter to filter the table rows (instead of conditional
formatting).
- Avoid large repeating data structures that can grow to many pages.
-Avoid complex nesting of optional and repeatable sections. These are quite complicated to layout and also can quickly cause a single view to become very large.
- Avoid using Percentage width for your controls if your view contains lots of nested controls. We have seen over 50% improvements by using Fixed Width. You can apply specify a fixed width in the control's properties dialog.
- Be aware of exactly what your business logic does. For example, onAfterChange can fire multiple times for a single edit.
- Rather than querying for all the data then having InfoPath just show a small amount, refine your query and only bring the data you plan on displaying into InfoPath.
- Only get the data you need to load the form. Don't pre-populate data sources that aren't necessary on load.
- Merge static xml data sources into one if you have multiple xml data connections.
- Use Expression Box to display calculated value if you don't need to store the value. If you have business logic to trigger all the calculation, only trigger necessary calculation. Triggering large amount of calculations is costly.
- When using digital signatures, only digitally sign the information you need to. Signing takes a screenshot of the data signed and encodes it in the form. The larger the screenshot, the larger the xml will become with the encoded image.
- Avoid attaching large files to the form. These files are encoded in the xml and can cause issues if they become too large. Provide links over embedding large files if possible.
- Avoid embedding images in a form. For the same reasons as above.

SharePoint Designer opens in contributor mode

No comments  
We may face some situation, while editing the site using Sharepoint Designer, it will get open in Contributor mode and we will not be able to edit the site, eventhough we have the Site Collection Administrator(SCA) permission.
 By default, Contribute permissions are assigned to the Site Collection Members  group. Even though, we are part of SCA group, if we are member of Site Collection members the Designer will open in Contributor mode.
To overcome this just disable the contributor settings in SharePoint designer by using the below steps:
1. Open the site in SharePoint Designer.
2. Select the Site Tab -> Contributor Settings.
3. Click on Disable Contributor settings button.
Now we will be able to edit the site.

How to convert Infopath form to word document

5 comments  
Sometimes you may need to convert an InfoPath form into a Word document so you can send it to users that either don’t have InfoPath or can’t access your  SharePoint form library. Luckily there is an easy process to do so.
Steps to convert InfoPath form to Word:
1) Open your .xsn InfoPath project file
2) Go to File -> Export To -> Web
3) Enter a name for the file and make sure “Single File Web Page (*.mht;*.mhtml)” for Save as type is selected. Click Export
4) Locate your new .mht file and open it with Word.
5) You should see your InfoPath form in Word. You may have to adjust any checkboxes or radio buttons that may be on the form. Make sure to save the file as a .doc or .docx file type when you’re done

Checking whether a file uploaded is of .doc or .docx file format

1 comment  
We can use the Java Script to check whether the file uploaded is of 2003 or 2007 word format. Hence we can handle the validation in the client side.
Java Script
<script type="text/javascript" language="javascript">
   function FileFormatValidate()
   {
        var uploadControl = document.getElementById('<%=FileUpload1.ClientID%>').value;
        //Regular Expression for the fileupload control.
        var reg = /^(([a-zA-Z]:)|(file://%7b2%7d/w )/$?)(//(/w[/w].*)) (.doc|.docx|.DOC|.DOCX)$/;
        //Checking if the file is empty or not
        if (uploadControl.length > 0) 
        {
            //Checks with the control value.
            if (reg.test(uploadControl)) 
            {
                return true;
            }
           else 
            {
                //If the condition not satisfied shows error message.
                alert("Only .doc, docx files are allowed!");
                return false;
            }
         }
        else 
        {
            //If the File is Empty or No File is  selected to upload shows this 
error message.
            alert("Please select a file to Upload");
            return false;
        }
    } //End of function FileFormatValidate.
</script>
Design
<p style="height: 28px; width: 216px">
    <asp:Button ID="btn_Upload" runat="server" Height="25px" 
        onclick="btn_Upload_Click" OnClientClick="return FileFormatValidate();" Text="Upload" Width="128px" />
</p>

Hence you can validate and check the file being uploaded at the client side using this code. This can be re-used for any file formats by changing the Regular Expression.
Happy Coding!!!
