Showing default sharepoint context menu with items in custom webparts : SharePoint 2010



While developing custom webparts, we often come across a requirement where in we need to show items from multiple lists in a grid like interface.While SPGridView is a nice control to achieve that,it has its own limitations when it comes to out of box features of sharepoint like showing default sharepoint context menu with options like 'View Properties' ,'Edit Properties' etc.


Usually , to create a context menu using SPGridView, we need to create a 'SPMenuField' in the grid and write our own code for each of the menu items.This approach is difficult to be able to achieve out of the box menu options like 'View Properties','Edit properties' etc.


The other option is to embed the javascript that sharepoint generates for context menu in the page's html. This way, this javascript would take care of rendering the context menu for us.This is the method that I have used to render this context menu.


In order to achieve this, I created a SPGridView with 'BoundField' instead of 'SPMenufield' in the user control (.ascx) of the visual webpart:


<SharePoint:SPGridView ID="gvMyDocuments" AutoGenerateColumns="false"
    runat="server" AllowSorting="true" onsorting="gvMyDocuments_Sorting"
    OnRowDataBound="gvMyDocuments_RowDataBound">
    <Columns>
    <asp:TemplateField>
    <ItemTemplate>
            <asp:Image runat="server" ID="imgDocIcon" ImageUrl="/_layouts/images/icgen.gif"/>
            <asp:Image runat="server" Visible="false" ID="imgOverlay" CssClass="ms-vb-icon-overlay" ImageUrl="/_layouts/images/icgen.gif"/>
    </ItemTemplate>
    </asp:TemplateField>
    <asp:BoundField HeaderText ="Name" DataField="Title" HtmlEncode="false" HtmlEncodeFormatString="false" SortExpression="Title" HeaderStyle-HorizontalAlign="Left"/>
    <asp:BoundField HeaderText ="Modified" DataField="Modified" SortExpression="Modified" HeaderStyle-HorizontalAlign="Left"/>
    <asp:BoundField HeaderText ="ModifiedBy" DataField="ModifiedBy" SortExpression="ModifiedBy" HeaderStyle-HorizontalAlign="Left"/>
    <asp:BoundField HeaderText ="ID" DataField="ID" itemstyle-cssclass="hiddencol" HeaderStyle-CssClass="hiddencol" HeaderStyle-HorizontalAlign="Left"/>
    </Columns>
    <RowStyle HorizontalAlign="Left" VerticalAlign="Middle" />
</SharePoint:SPGridView>





While creating the entity collection to be bound with the grid view,I created the html and assigned it to the Title field (to be bound with the 'Name' field of the GridView).

The code for creation of this html is as follows:

objRelationships.Title = GenerateTitleHtml(strNameWoExt, objSPListItem.Url, itemCount, objSPListItem.ID, objSPListItem.ParentList, objSPListItem);


where:
 objSPListItem is the current SPListItem object being populated.
 strNameWoExt is the document name (without extention)
 objSPListItem.Url is the url for the current list item
 itemCount is a unique number being incremented everytime to maintain a unique id.
 objSPListItem.ID is the id of the list item.
 objSPListItem.ParentList is the parent list of the list item.



The method 'GenerateTitleHtml' creates all the html necessary for creating
the context menu :

public virtual String GenerateTitleHtml(String strTitle, String strFileUrl, Int32 itemCount, Int32 ItemID, SPList itemParentList, SPListItem currentListItem)
        {
            StringBuilder sbHtml = new StringBuilder();

            String ctxMenuJavascriptHtml = CreateContextMenu(itemParentList, itemCount);

            if (!String.IsNullOrEmpty(ctxMenuJavascriptHtml))
            {
                sbHtml.Append(ctxMenuJavascriptHtml);
            }

            String strCtxId = itemCount.ToString() + Math.Abs(itemParentList.ID.GetHashCode()).ToString().Substring(0, 3);

            sbHtml.Append("<div class='ms-vb itx' onmouseover='OnItem(this)' ctxname='ctx" + strCtxId + "' id='" + ItemID + "' Field='LinkFilename' Perm='0x7fffffffffffffff' EventType=''>");
            sbHtml.Append("<a onclick=\"" + GetDispEx(currentListItem, itemCount) + "\" href='/" + strFileUrl + "' onfocus='OnLink(this)'>" + strTitle + "<img height='1' border='0' width='1' alt='Use SHIFT+ENTER to open the menu (new window).' class='ms-hidden' src='/_layouts/images/blank.gif'></a>");
            // sbHtml.Append(strTitle);
            sbHtml.Append("</div>");
            sbHtml.Append("<div class='s4-ctx' onmouseover='OnChildItem(this.parentNode); return false;'>");
            sbHtml.Append("<span> </span>");
            sbHtml.Append("<a onfocus='OnChildItem(this.parentNode.parentNode); return false;' onclick='PopMenuFromChevron(event); return false;' href='javascript:;' title='Open Menu'></a>");

            sbHtml.Append("</div>");

  1. Hi Bhavya!

    Could you give me more detail about this statement: "objRelationships.Title = GenerateTitleHtml(strNameWoExt, objSPListItem.Url, itemCount, ......)"

    where the "objRelationships" came from???

    Many Thanks,
    Jay

    ReplyDelete
  2. Hi Jay,

    objRelationships is basically our entity class object which we are binding with the SPGridView.

    The Title property in this entity class is bound with the 'Name' field in the SPGridView.

    You can get the html for the context menu generated by calling the 'GenerateTitleHtml' method and can assign it to any field in you own entity class.

    Thanks,
    Bhavya

  3. Hi,

    I have been looking for this for a while. Was going to give up my project but you made my day!

    Instead of a gridView, i have to use a treeview in my webpart. Do you think i can use your code as well on my treeview nodes?

    What about customMenuActionsDivListIDs? it is not defined in the code above.

    Thanks in advance

  4. Hi Mathieu,

    Yes, you can use the same code with a treeview as well.

    Please carry out the following steps:

    1. Remove the SPGridview from the user control for the visual webpart (.ascx).
    2. Add a treeview to the user control like this:


    <asp:TreeView ID="TreeView1" runat="server">

    </asp:TreeView>


    3. Add the following code on 'Page_Load' in order to populate the treeview with the entity collection containing the 'Title' field.(For eg.,in this case, it is 'objRelationshipCollection').

    The 'Title' field of this collection contains the HTML code generated for the context menu.

    TreeNode tvRootNode = new TreeNode("Root", "Root");

    foreach (ENTITES.Relationships objRelationShip in objRelationshipCollection)
    {
    TreeNode tvNode = new TreeNode(objRelationShip.Title, objRelationShip.Name, objRelationShip.IconImagePath);
    tvRootNode.ChildNodes.Add(tvNode);
    }

    TreeView1.Nodes.Add(tvRootNode);
    TreeView1.ShowExpandCollapse = true;
    TreeView1.ShowLines = true;

    This will generate the treeview with a context menu being displayed for each node.


    As far as 'customMenuActionsDivListIDs' is concerned, you can declare it as a class level variable like this:

    private List<String> customMenuActionsDivListIDs = new List<String>();

  5. Thanks a lot for your time, very usefull.
    I made a first attempt with a non visual webpart befor your post. Strugleed a litle bit but i started to have result.
    Will try with a visual webpart as well if i have difference in the rendering of the contextual menu.
    Have a nice day

  7. Hi Bhavya,

    I am new to sharepoint.
    Can you please share your complete code.

    This seems to be something I had been looking for but unable to gather together.
    I think I have some missing pieces.

  9. Hi Kanishka,

    Due to confidentiality reasons,I won't be able to share the complete source code but am happy to help in resolving the issues that you are facing.

    Usually ,this issue occurs due to the html encoding on the gridview field bound with the context menu html.

    As stated in the code snippet above, you have to set 2 properties HtmlEncode="False" and HtmlEncodeFormatString="false"

    <asp:BoundField HeaderText ="Name" DataField="Title" HtmlEncode="false" HtmlEncodeFormatString="false" SortExpression="Title" HeaderStyle-HorizontalAlign="Left"/>

    Did you set these 2 properties?

    Thanks,
    Bhavya

    Thank you very much for posting your solution here, really nice way of creating the "standard menu" for SharePoint.

    I have almost got it to work but I am struggling with getting the "edit properties" and "view properties" functions in the menu to work.

    When these are pressed nothing happens and when debugging in explorer i get the following exception "Unable to retrieve the value of the property clvp: object is null or undefined" when triggering the javascript function EditItem2. This javascript function is called when the view properties is pressed.

    I have your solution hooked up against a document library and everything else in your custom menu, such as view version history, workflows etc works.

    If you have the time to help me I would be very happy!

    Thank you!

  11. Hi Bhavya,

    I had used SPSiteDataQuery to fetch the documents across multiple document libraries and displayed it in a SPGridView. Now I need to enable the default context menu to it. Please guide me on how to accomplish this. Method "GenerateTitleHtml" requires parameter like SPListItem's Id, url. Can you please assist me in doing it.

    Thanks in advance !
    Arun

  16. Hi ... thanks for your article. I tried your solution and it works perfectly (SPGridView with BoundField rendered in Webpart over SharePoint Server 2010).

    I only have one question ... the first menu item once opened and closed the first time is not it opens more. The behavior occurs only with the first menu item, the others work perfectly but the fist open it only one time.

    Have you also experienced this behavior?

    1. Hi Pietro,

      I haven't experienced this behaviour earlier but going by the description, I think it might have something to do with multiple instances of this webpart or any other list view webpart on the same page.

      This might result in the javascript being emitted multiple times on the page which might cause this behaviour.

      If this is the case, then please try removing all other webparts from the page and test with only 1 instance of this webpart on the page.

      Thanks,
      Bhavya
