Here I am going to explain how we can get the first date and last date for selected month and year from asp.net calender control. Here we just need quite easy logic on 2 events on calender. The events are Prerender and Dayrender. In PreRender, I have take session as null so everytime when page is loading, it get null before processing on calender days. Then I have write some logic to show FirstDate, Lastdate and also same for each week in the month.

C# Code
protected void Calendar1_PreRender(object sender, EventArgs e)
{
Session["FirstDay"] = null;
Session["LastDay"] = null;
}

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (Session["FirstDay"] == null)
Session["FirstDay"] = e.Day.Date;

if (Session["LastDay"] == null)
Session["LastDay"] = e.Day.Date.AddDays(41);

string LastDates = Convert.ToDateTime(Session["LastDay"]).ToShortDateString();
if (e.Day.Date.ToShortDateString() == LastDates)
{
DateTime FirstDate = Convert.ToDateTime(Session["FirstDay"]);
DateTime LastDate = Convert.ToDateTime(Session["LastDay"]);
Response.Write(“FirstDay:”+Session["FirstDay"].ToString() + “<br />”);
Response.Write(“LastDay:”+Session["LastDay"].ToString() + “<br />”);
for (DateTime i = FirstDate; i <= LastDate; )
{
DateTime WeekStart = i;
DateTime WeekEnd = i.AddDays(6);
Response.Write(“Week Start: ” + WeekStart.ToShortDateString() + “<br />”);
Response.Write(“WeekEnd: ” + WeekEnd.ToShortDateString() + “<br /><br />”);
i = i.AddDays(7);
}
}
}

I have also attached screen for better understand. I hope this will be helpful for you guys.

Thanks

public DataTable RemoveDuplicateRows(DataTable dTable, string colName)
{
Hashtable hTable = new Hashtable();
ArrayList duplicateList = new ArrayList();

foreach (DataRow drow in dTable.Rows)
{
if (hTable.Contains(drow[colName]))
duplicateList.Add(drow);
else
hTable.Add(drow[colName], string.Empty);
}

foreach (DataRow dRow in duplicateList)
dTable.Rows.Remove(dRow);

return dTable;
}

protected void btnRemoveDuplicate_Click(object sender, EventArgs e)
{
Fill your dataset
string strConn = ConfigurationManager.ConnectionStrings["Your Connection String key from config file"].ToString();
SqlConnection conn = new SqlConnection(strConn);
SqlDataAdapter da = new SqlDataAdapter(“select * from Test”, conn);
DataSet ds = new DataSet();
da.Fill(ds, “Test”);

Take Temporary table and store 0th position’s table from dataset in your temp table.
DataTable dt = ds.Tables["Test"];

Pass that temp table in above method, so it return fresh table with duplicating rows. You must have to define the columnname for which you are going to remove duplicate rows. Here in example, “Name” column is passed for duplicate wors removal.
dt = RemoveDuplicateRows(dt, “Name”);

You have fresh table with distinct records here in dt table, you can assign in dataset of bing to your any data control
dgTest.DataSource = ds.Tables["Test"].DefaultView;
dgTest.DataBind();
}

I hope it helpful for you.

Take one HeaderTemplate column and add one checkbox with ID=cbheaderCategory

Take one ItemTemplate column and add one checkbox with ID=chkDeleteCategory

Add following vb.net code in code behind file
Protected Sub dgrdCategory_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgrdCategory.ItemDataBound
If (e.Item.ItemType = ListItemType.Header) Then
Dim chk As CheckBox = CType(e.Item.Cells(0).FindControl(“cbheaderCategory”), CheckBox)
chk.Attributes.Add(“onclick”, “SelectAllCheckboxesCategoryList(‘” + chk.ClientID + “‘);”)
End If

If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem) Then
Dim chk As CheckBox = CType(e.Item.Cells(1).FindControl(“chkDeleteCategory”), CheckBox)
chk.Attributes.Add(“onclick”, “UncheckAllCategoryList(‘” + chk.ClientID + “‘);”)
End If
End Sub

To add event to check selected check boxes and confirmation message on delete button, use following code.

btnDelete.Attributes.Add(“OnClick”, “javascript: return ConfirmDelete();”)

I hope it helps you.

Here we don’t need to provide the path. We just have to create Linked resource and Alternative view  from the mail message object. Now we just have to provide the Resource Id to Alternative view object and bind that linked resource to alternative view’s object. That’s all.  See the following code with example…

//Holds message information.
System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
//Add basic information.
mailMessage.From = new System.Net.Mail.MailAddress(txtFrom.Text.Trim());
mailMessage.To.Add(txtTo.Text.Trim());
mailMessage.Subject = txtSubject.Text.Trim();

//Add image to HTML version
string path = Server.MapPath(@”Your Image Name.extention”); // my logo is placed in images folder

System.Net.Mail.LinkedResource imageResource = new System.Net.Mail.LinkedResource(path, “image/gif”);
imageResource.ContentId = “HDIImage”;
//Create two views, one text, one HTML.
System.Net.Mail.AlternateView htmlView = AlternateView.CreateAlternateViewFromString(“
” + txtBody, null, MediaTypeNames.Text.Html);
htmlView.LinkedResources.Add(imageResource);

mailMessage.AlternateViews.Add(htmlView);
mailMessage.IsBodyHtml = true;
//Send message
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient(“Your Mail Server Name”);
//SmtpClient client = new SmtpClient(strSMTPserver);
smtpClient.Credentials = new NetworkCredential(“Username”, “Password”);
smtpClient.Send(mailMessage);

Thanks you and hope this article will help you lot’s

It get the current name of your machine and compare with domain which you have defined in webconfig file.

You must have Domain name and its password so you can check your machne name in active directory of that domain.

using System.DirectoryServices;

public Boolean CheckActiveDirectory(string strUsername)
{
DirectoryEntry de = null;
DirectorySearcher searchUser = null;
DirectoryEntry localMachine = null;
DirectorySearcher search = null;

try
{
string struser = ConfigurationSettings.AppSettings["DomainUserName"];
string domainName = ConfigurationSettings.AppSettings["DomainName"];
string servername = ConfigurationSettings.AppSettings["serverpath"];
string pwd = ConfigurationSettings.AppSettings["DomainPassword"];
string domainAndUsername = strUsername;// domainName + “\\” + struser;

localMachine = new DirectoryEntry(“LDAP://” + servername, domainAndUsername, pwd);
search = new DirectorySearcher(localMachine);

search.Filter = “(&(objectcategory=user)(name=*))”;
search.SearchScope = SearchScope.Subtree;
search.PropertiesToLoad.Add(“cn”);

string userid = Convert.ToString(Session["CurrentUser"]);
string[] strUserDetails = userid.Split(‘\\’);
bool StatusFlag = false;
if (Convert.ToString(strUserDetails[0]) == domainName)
{
foreach (SearchResult sr in search.FindAll())
{
de = sr.GetDirectoryEntry();
strUsername = de.Properties["sAMAccountName"].Value.ToString();
if (Convert.ToString(strUserDetails[1]) == strUsername)
{
StatusFlag = true;
break;
}
}
}
return StatusFlag;

The whole concept behind this is somethng like to insert some text where your mouse cursor in other text ares.

Here i have taken one DataList control and one multiline textbox. I have filled 3 countryname in DataList control.
In ItemDataBound event of datalist control, i have set Attributes on onclick client side event, I have pass client id of control which contain the name of 3 countres and called one function insertAtCursor().

Here we get the start and end points of the selection. Then we create substrings up to the start of the selection and from the end point of the selection to the end of the field value. Then we concatenate the first substring, myValue, and the second substring to get the new value.

Javascript:

<script type=”text/javascript” language=”javascript”>
function insertAtCursor(myValue)
{
if (document.selection)
{
document.getElementById(‘<%=txtBody.ClientID %>’).focus();
sel = document.selection.createRange();
sel.text = myValue;
}

else if (document.getElementById(‘<%=txtBody.ClientID %>’).selectionStart >= ’0′)
{
var startPos = document.getElementById(‘<%=txtBody.ClientID %>’).selectionStart;
var endPos = document.getElementById(‘<%=txtBody.ClientID %>’).selectionEnd;
alert(document.getElementById(‘<%=txtBody.ClientID %>’).value.substring(0, startPos) + myValue + document.getElementById(‘<%=txtBody.ClientID %>’).value.substring(endPos, document.getElementById(‘<%=txtBody.ClientID %>’).value.length));
document.getElementById(‘<%=txtBody.ClientID %>’).value = document.getElementById(‘<%=txtBody.ClientID %>’).value.substring(0, startPos)+ myValue+ document.getElementById(‘<%=txtBody.ClientID %>’).value.substring(endPos, document.getElementById(‘<%=txtBody.ClientID %>’).value.length);
}
else
{
document.getElementById(‘<%=txtBody.ClientID %>’).value += myValue;
}
return false;
}
</script>
<!–
function insertAtCursor(myValue)
{
if (document.selection)
{
document.getElementById(”).focus();
sel = document.selection.createRange();
sel.text = myValue;
}

else if (document.getElementById(”).selectionStart >= ’0′)
{
var startPos = document.getElementById(”).selectionStart;
var endPos = document.getElementById(”).selectionEnd;
alert(document.getElementById(”).value.substring(0, startPos) + myValue + document.getElementById(”).value.substring(endPos, document.getElementById(”).value.length));
document.getElementById(”).value = document.getElementById(”).value.substring(0, startPos)+ myValue+ document.getElementById(”).value.substring(endPos, document.getElementById(”).value.length);
}
else
{
document.getElementById(”).value += myValue;

return false;
