SharePoint Blog: 2012

Whenever, I click on that image it displays us with a drop-down containing all the values, but the funniest part is you can select a particular item either by double click or by selecting it once and clicking it else where on the page or by tabbing system of the keyboard. But I want it work like a normal drop-down selection in other words just with a single click and also the control should be closer to other controls from usability perspective.

To fix this issue. you need to set InDesign ="true";

Ex.BaseFieldControl webControl = field.FieldRenderingControl;

webControl.ID = string.Format("ctrl_{0}_{1}", field.InternalName, pplCount);

webControl.FieldName = field.Title;

webControl.ItemContext = SPContext.GetContext(HttpContext.Current, lstReqData.DefaultView.ID, lstReqData.ID, lstReqData.ParentWeb);

webControl.RenderContext = SPContext.GetContext(HttpContext.Current, lstReqData.DefaultView.ID, lstReqData.ID, lstReqData.ParentWeb);

webControl.ControlMode = SPControlMode.New;

webControl.ListId = lstReqData.ID;

webControl.InDesign = true;

If you are using form field you can set it by following changes in aspx page

<SharePoint:FormField runat="server" InDesign="true" ID="myFieldId" ControlMode="New" FieldName="myFieldName" />

Use Metadata Navigation in Wiki Pages (Sharepoint 2010)

If you want to use Metadata navigation tree in Wiki Page, you have to do the following:

Activate Metadata Navigation and Filtering feature on site level

Navigate to Library settings page of your “Pages” library and select Metadata navigation settings
From “Configure Navigation Hierarchies” select “Wiki Categories” and click “Add” and “OK”

Navigate to Pages library again

http://<Your Wiki Site Url>/Pages/Forms/AllItems.aspx

But when you click on any of the pages on the right panel, the navigation tree will disappear.

You have to change the master page or better to create and deploy a new one (via Sharepoint Designer or wsp)
You have to include a reference to MetadataNavTree control and put it in some placeholder (QuickLaunchNav) on the master page file.

Put this markup in the beginning of the page

<%@ Register TagPrefix="wssuc" TagName="MetadataNavTree" src="~/_controltemplates/MetadataNavTree.ascx" %>

Put this code in <asp:ContentPlaceHolder id="QuickLaunchNav" runat="server"> tag

<asp:ContentPlaceHolder id="QuickLaunchNav" runat="server">
<wssuc:MetadataNavTree id="mdnt" runat="server" />

The result is:

Calling Javascript / Jquery / ECMA script from an UpdatePanel in SharePoint

You've probably used ClientScript.RegisterStartupScript in your SharePoint application page and it works just fine.

for example:-

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Close", "<script type=\"text/javascript\">SP.UI.ModalDialog.commonModalDialogClose(0);</script>");

However, if you try it within an UpdatePanel control, you would notice that it simply doesn't execute.

The solution to this problem is to use ScriptManager.RegisterStartupScript instead. You can call it like so:

ScriptManager.RegisterClientScriptBlock(UpdatePanelSites, UpdatePanelSites.GetType(), "Close", "SP.UI.ModalDialog.commonModalDialogClose(0);", true);

Select Distinct or Unique values from SharePoint List

I was looking around for the simple way of getting unique values from SharePoint list without affecting performance. I have seen several ways of doing it. For example, we can get all the items and then check if item exists in the array or some other collection. Another example, you can load your data into DataTable and then select unique values using DataTable method, following is snippet of code below on how to use it

GetUniqueColumnData("List Name", "ColumnName");

private void GetUniqueColumnData(string ListName, string ColumnName)
{
try
{
using (SPSite site = SPContext.Current.Site)
{
using (SPWeb web = site.OpenWeb())
{
DataTable dtList = new DataTable("TableName");
SPList list = web.Lists[ListName];
if (list != null)
{
SPQuery query = new SPQuery();
query.Query = "<OrderBy><FieldRef Name='" + ColumnName + "'/></Order By><FieldRef Name='" + ColumnName + "'/>";
dtList = list.GetItems(query).GetDataTable();
dtList = new DataView(dtList).ToTable(true, new string[] { ColumnName });
}
}
}
}
catch (System.Exception ex)
{
LoggingService.LogErrorInULS(ex.Message + "Stack Trace: "+ ex.StackTrace,TraceSeverity.High);
}
}

but I discovered one very simple method for selecting Distinct Values in SharePoint called GetDistinctFieldValues. Please see snippet of code below on how to use it

using (SPSite site = SPContext.Current.Site)
{
using (SPWeb web = site.OpenWeb())
{
SPList objList = web.Lists["List Name"];
SPField field = objList.Fields.GetField("Field Name");
Object[,] values;
uint numberValues = objList.GetDistinctFieldValues(field, out values);
for (int i = 0; i < numberValues; i++)
comboBox1.Items.Add(values.GetValue(0, i).ToString());

}
