Error : Cannot retrieve properties at this time and Cannot save your changes in content editor web part or html form webpart

Hello,

In Content Editor Web part or HTML Form Web part , when we are trying to edit the content in Source Editor sometimes we will get this error .

The reason for this is while copying the content from word/some other tools, the format also carried along with the copied text. This format cannot be understand by SharePoint. This is the reason it throws the error. Even though your text appeared on the web part sometimes throws the error while saving the web part.

While saving the Source Editor throws “Cannot retrieve properties at this time ” like this

and while saving the web part it throws this error “Cannot save your changes”.

Solution :

• This is the issue with the browser version you are using, I got this error with IE10. I tried by editing the same with IE8, It worked for me. ( as per my observation this is not working with chrome and IE versions above IE8. )
• Recycle the application pool – This is based on the information we get on the logs. But this is not working all the times.

Thanks,

How to Clear SharePoint Designer Cache

Hello guys,

This post gives  you the information on how to clear the cache which is created by SharePoint Designer. Generally when you log in to the designer you see the info of already opened sites/pages . This is due to the cache which is created by designer when you login/open the site.

Follow these steps to clear the cache.

 

Close the designer and delete the files from below folders(Open these folders in windows explorer)

 

• %APPDATA%\Microsoft\Web Server Extensions\Cache
• %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache

If you want to clear the cache frequently ,write a batch file with these commands to run with single click.

Thanks,

SharePoint List Export to Excel in Java Script Client Object Model using RPC (Owssvr.dll)

Hello guys,

Here I am explaining how to implement the OOB 'Export to Excel' feature of SharePoint list using RPC (Remote Procedure Calls) with Javascript CSOM code.

What is RPC :

This is a protocol from Windows SharePoint Services(WSS) , helps in exchanging the data between client and the server which runs with WSS. As all of you know the foundation for Sharepoint Server is came from WSS.

So for this kind of functionalities we can make use of this RPC. Here more about RPC from msdn.

Here I am using this below rpc url to generate the excel report of a list

 "/_vti_bin/owssvr.dll?CS=109&Using=_layouts/query.iqy&List={" + listId + "}" + "&View={" + viewId + "}&CacheControl=1";           

The parameters are List GUID and the View GUID.

Get List GUID :

Go to your list settings page: List Settingsà in Url you will find

http:// purnaexperiments:1234/_layouts/15/listedit.aspx?List=%7BCEB4F6D3%2D06AC%2D43FF%2DA95E%2DA158144585A3%7D

Replace  %7B with “{“,

             %2D with “–“ and

             %7D with “}”

After this the you get the GUID like ={CEB4F6D3-06AC-43FF-A95E-A158144585A3}.

Get View Guid :

Go to List Viewà Click Modify this ViewàYour url will look like this follow url

http://purnaexperiments:1234/_layouts/15/ViewEdit.aspx?List=%7BCEB4F6D3%2D06AC%2D43FF%2DA95E%2DA158144585A3%7D&View=%7BE42BBCD5%2D8A0F%2D4092%2D8B3D%2D52D9EF805AAB%7D

Copy the value after the string ‘View’ in above url and

Replace  %7B with “{“,

             %2D with “–“ and

             %7D with “}”

After this the you get the View GUID like ={ E42BBCD5-8A0F-4092-8B3D-52D9EF805AAB}.

In below code I am getting the LIST GUID and View GUID from their names. 

You can use this function directly to generate the report with List Title and View Title

Code :

1.   <input id="btnGenerate" onclick=" GeneratePCMReport('MyCustomList', 'All Items’);" value="Generate Excel Report" /> 
2. // Here the list name is 'MyCustomList' and the view name is ‘All Items’ 
3. 
   
4.     <script type="text/javascript">    
5.         var exporturl = null;
6.         var listPages = null;
7.         var view = null;
8.         var web = null;
9.         function GeneratePCMReport(listName, viewTitle)         
10.         { 
11.             if (navigator.appName == "Microsoft Internet Explorer") 
12.                {
13.                 var context = new SP.ClientContext.get_current();
14.                 web = context.get_web();
15.                 context.load(web);
16.                 listPages = context.get_web().get_lists().getByTitle(listName);
17.                 context.load(listPages);
18.                 view = listPages.get_views().getByTitle(viewTitle);
19.                 context.load(view);
20.                 context.executeQueryAsync(getlistInfoSuccess, getlistInfoFailed);
21.                 }
22.             else {
23.                 alert("Please use Internet Explorer to generate the Excel Report");
24.             }
25.         } 
26.         function getlistInfoSuccess(sender, args)
27.         {
28.             var listId = listPages.get_id();
29.             var viewId = view.get_id();
30.             exporturl = web.get_url() + "/_vti_bin/owssvr.dll?CS=109&Using=_layouts/query.iqy&List={" + listId + "}" + "&View={" + viewId + "}&CacheControl=1";          
31.             window.location.href = exporturl;
32.         }
33.         function getlistInfoFailed(sender, args) 
34.          {
35.             alert('Issue in getting the Report, Please try later')
36.          } 
37.     </script>

Note : As you know the oob  'Export to Excel' works only in IE, the above code also works only in IE.

Since we are calling the same oob function through csom code. That is the reason i have included a condition (navigator.appName == "Microsoft Internet Explorer") in above code to check the browser type.

Thanks,

Purna

How to check the browser is IE or not using javascript

Generally while working with some share point functionalities there will be need of checking the type of broswer.

Especially the functionalities like export to excel. Calling default 'Export Excel' feature in our custom code needs this browser check.

This is the java script code to check this

if (navigator.appName == "Microsoft Internet Explorer")

{

   alert('This is IE');

}

else

{

  alert('This is Not IE');

}

Getting Data from Managed Metadata Column using JavaScript Client Side Object Model

Hello,

In this post I am explaining a small topic, how to get data from managed metadata filed using JavaScript client object model.

The reason to write this post is, generally if it is multi data column we check the count of the items and loop through it to get the values of it. But here with meta data columns the syntax is little different, we need to use child item count and loop through it and get the label property of it.

Generally we contain two types of settings for Manged Metadata column

Single valued Metadata Column (setting: Allow Multiple Values – False) : This contains single value

Multivalued Metadata Column (setting:    Allow Multiple Values – True)  : This contains single/multiple values.

Code to get the data from Singlevalued Metadata Column

Here the column name is 'ProductName'

//Single Valued Metadata column

var resultProductName = "";

        var _ProductName =  listItem.get_item('ProductName')

        if (typeof _ProductName !== 'undefined' && _ProductName !== null) 

        {

            resultProductName = listItem.get_item('ProductName').Label;

        }

  alert("Product Name " + resultProductName);

Code to get the data from Multivalued Metadata Column

  //Multi Valued Metadata column with single/multiple values

Here the column name is 'ProductColors'

 var resultColorString = "";

      

        var _ProdColors = listItem.get_item('ProductColors');    

        if (typeof _ProdColors !== "undefined" && _ProdColors !== null) {

            if (_ProdColors._Child_Items_.length > 0)

            {

                if (_ProdColors._Child_Items_.length == 1)// If single value

                {

                    var color = _ProdColors._Child_Items_[0].Label;

                    resultColorString = color;                  

                }

                else// If multi value

                {

                    for (var i = 0; i < _ProdColors._Child_Items_.length ; i++)

                    {

                        var multicolor = _ProdColors._Child_Items_[i].Label;

                        if (multicolor != null) {

                            resultColorString = resultColorString + "," + multicolor;

                        }

                    }

                    if (resultColorString.length > 0) {

                        resultColorString = resultColorString.substring(1, resultColorString.length);

                    }                   

                }

            }

        }    

       alert('color(s) ' + resultColorString)

Hope it saves some one's time :)

Thanks,
