</cc1:ModalPopupExtender>
TargetControlID - to invoke the modalpopupextender
PopupControlID - panel Control id
PopupDragHandleeControlId = which part to drag
CancelControlId - to canel the modalpopupextender
4. Cancel button event
pnlForgotPwd.Style.Add("display", "none");
btnForgotPwd_ModalPopupExtender.Hide();
txtLoginID.Text = "";
upMain.Update();
5. How to show error while popupwindow
a) create one more panel with required control to display error message
<div id="MsgBox" runat="server">
</div>
<asp:Panel ID="pnlOuterMsgBox" runat="server" CssClass="outerPopup" Style="display: none;">

<br />
<br />
<asp:ImageButton ID="btnOK" runat="server" ImageUrl="~/images/ok.png" />
<br />
</asp:Panel>
</asp:Panel>
b) create one more modalpopextender
<cc1:ModalPopupExtender ID="mpeMsgBox" runat="server" TargetControlID="MsgBox" PopupControlID="pnlOuterMsgBox"
CancelControlID="btnCancel" OkControlID="btnOK" BackgroundCssClass="BGCSS" />
<asp:Button ID="btnCancel" runat="server" Text="Cancel" Enabled="false" />
success and not success
if (objUser.CheckUserExists(txtLoginID.Text))
{
lblMsgBox.ForeColor = System.Drawing.Color.Green;
imgMsgBox.ImageUrl = "~/images/id_ok.png";
lblMsgBox.Text = " Password successfully send to your HP Number.";
txtLoginID.Text = "";
mpeMsgBox.Show();
pnlForgotPwd.Style.Add("display", "none");
btnForgotPwd_ModalPopupExtender.Hide();
upMain.Update();
}
else
{
lblMsgBox.ForeColor = System.Drawing.Color.Red;
imgMsgBox.ImageUrl = "~/images/id_occ.png";
lblMsgBox.Text = " Incorrect Login ID.";
mpeMsgBox.Show();
pnlForgotPwd.Visible = true;
btnForgotPwd_ModalPopupExtender.Show();
upMain.Update();
}
45. to focus popupwindow
function openPopup(purl)
{
wndAttr = "width=520,height=630,left=100,top=100";
var w = window.open(purl, 'popup_test', wndAttr);
w.focus();
}
46. retrieve page records
command.ExecutePageReader(CommandBehavior.Default, 1, 10);

}
49. convert linq to datatable
public DataTable LINQToDataTable<T>(IEnumerable<T> varlist)
{
DataTable dtReturn = new DataTable();
// column names
PropertyInfo[] oProps = null;
if (varlist == null) return dtReturn;
foreach (T rec in varlist)
{
// Use reflection to get property names, to create table, Only first time, others
//will follow
if (oProps == null)
{
oProps = ((Type)rec.GetType()).GetProperties();
foreach (PropertyInfo pi in oProps)
{
Type colType = pi.PropertyType;
if ((colType.IsGenericType) && (colType.GetGenericTypeDefinition() == typeof(Nullable<>)))
colType = colType.GetGenericArguments()[0];
dtReturn.Columns.Add(new DataColumn(pi.Name, colType));
}
}
DataRow dr = dtReturn.NewRow();
foreach (PropertyInfo pi in oProps)
{
dr[pi.Name] = pi.GetValue(rec, null) == null ? DBNull.Value : pi.GetValue
(rec, null);
}
dtReturn.Rows.Add(dr);
}
return dtReturn;
}
LINQToDataTable(ResultMenuAcc); // var ResultMenuAcc result

txtPassword.Attributes.Add("onKeyPress", "javascript:if (event.keyCode == 13) __doPostBack('" + btnLogin.UniqueID + "','')");
52. Split only number from string exx. adsfad1234
you can use regular expression to split the value
ex.
string val ="SCV 5000";
Regex r = new Regex("^[0-9]$");
string[] tmpval = r.Split(val);
tmpval[1] = have numberic values
tmpval[0] = character values

var array = temp.split(" ");
array.sort();
temp = array.join(" ");
55. Without prompting close button message
function CloseWindow()
{
window.open('','_self','');
window.close();
}
56.. Refresh page

</ContentTemplate>
</asp:UpdatePanel>
protected void Timer1_Tick(object sender, EventArgs e)
{
}
57. to populate the file and folder in tree
public void PopulateTree(string dir, TreeNode node) {
// get the information of the directory
DirectoryInfo directory = new DirectoryInfo(dir);
// loop through each subdirectory
foreach(DirectoryInfo d in directory.GetDirectories()) {
// create a new node
TreeNode t = new TreeNode(d.Name);
// populate the new node recursively
PopulateTree(d.FullName, t);
node.Nodes.Add(t); // add the node to the "master" node
}
// lastly, loop through each file in the directory, and add these as nodes
foreach(FileInfo f in directory.GetFiles()) {
// create a new node
TreeNode t = new TreeNode(f.Name);
// add it to the "master"
node.Nodes.Add(t);
}
}
