Remove duplicates from DataSet in .Net

da.Fill(ds,"Details");
DataTable dt = ds.Tables["Name"];
RemoveDuplicateRows(dt, "Name"); // Here Name is Column name of table
gvDetails.DataSource = ds;
gvDetails.DataBind();

// This method is used to delete duplicate rows of table
public DataTable RemoveDuplicateRows(DataTable dTable, string colName)
{
Hashtable hTable = new Hashtable();//hash table is used to store different types of data.It will take two parameters as input[Value and Name].
ArrayList duplicateList = new ArrayList();
foreach (DataRow dtRow in dTable.Rows)
{
if (hTable.Contains(dtRow[colName]))
duplicateList.Add(dtRow);
else
hTable.Add(dtRow[colName], string.Empty);
}
foreach (DataRow dtRow in duplicateList)
dTable.Rows.Remove(dtRow);
return dTable;

Maintain the state of Checkbox values in GridView

Write the below two methods[PageIndexChanging] to save the checkbox values in gridview when paging is set to true.
        private void SaveCheckedValues()
        {
            ArrayList userdetails = new ArrayList();
            int index = -1;
            foreach (GridViewRow gvrow in gvdetails.Rows)
            {
                index = (int)gvdetails.DataKeys[gvrow.RowIndex].Value;
                bool result = ((CheckBox)gvrow.FindControl("chkSelect")).Checked;

                // Check in the Session
                if (Session["CHECKED_ITEMS"] != null)
                    userdetails = (ArrayList)Session["CHECKED_ITEMS"];
                if (result)
                {
                    if (!userdetails.Contains(index))
                        userdetails.Add(index);
                }
                else
                    userdetails.Remove(index);
            }
            if (userdetails != null && userdetails.Count > 0)
                Session["CHECKED_ITEMS"] = userdetails;
        }
        private void PopulateCheckedValues()
        {
            ArrayList userdetails = (ArrayList)Session["CHECKED_ITEMS"];
            if (userdetails != null && userdetails.Count > 0)
            {
                foreach (GridViewRow gvrow in gvdetails.Rows)
                {
                    int index = (int)gvdetails.DataKeys[gvrow.RowIndex].Value;
                    if (userdetails.Contains(index))
                    {
                        CheckBox myCheckBox = (CheckBox)gvrow.FindControl("chkSelect");
                        myCheckBox.Checked = true;
                    }
                }
            }
        }

To show the GridView with no rows/data

Add the below code before binding the data to GridView
 if (ds.Tables[0].Rows.Count == 0)
        {
            ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
            grdview.DataSource = ds;
            grdview.DataBind();
            int columncount = grdview.Rows[0].Cells.Count;
            grdview.Rows[0].Cells.Clear();
            grdview.Rows[0].Cells.Add(new TableCell());
            grdview.Rows[0].Cells[0].ColumnSpan = columncount;
            grdview.Rows[0].Cells[0].Text = "No Records Found";
        }
        else
        {
            grdview.DataSource = ds.Tables[0];
            grdview.DataBind();
        }

Dynamics CRM 2011 - Trigger a workflow from JavaScript

Recently I had a requirement to trigger a workflow on click of ribbon button when it meets certain criteria. Refer below link for calling JavaScript function from custom ribbon button.
http://ankit.inkeysolutions.com/2012/01/crm-2011-how-to-use-visual-ribbon.html
The criteria values are checked using JavaScript and if all criteria are satisfied then the workflow is to be triggered. The function below will take two inputs where entityId is the id of the record for which the workflow will execute and workflowProcessId is the id of the workflow which we want to execute. 

function startWorkflow(entityId, workflowProcessId) {

  var xml = "" +    "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +

 "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +  Xrm.Page.context.getAuthenticationHeader() +  "<soap:Body>" +"<Execute xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" +"<Request xsi:type=\"ExecuteWorkflowRequest\">" +"<EntityId>" + entityId + "</EntityId>" +  "<WorkflowId>" + workflowProcessId + "</WorkflowId>" + "</Request>" +"</Execute>" +"</soap:Body>" +"</soap:Envelope>";

var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");

xmlHttpRequest.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);

xmlHttpRequest.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/crm/2007/WebServices/Execute");

xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");

  xmlHttpRequest.setRequestHeader("Content-Length", xml.length);

  xmlHttpRequest.send(xml);
