}
lblScripter.Text = #"<script type=""text/javascript"">SP.SOD.executeOrDelayUntilScriptLoaded(function() {showInfo('" + MessageShow + "');}, 'sp.js');</script>";
if (Currenttime >= Enddate)
{
lblScripter.Text = "hi after date tim refreshed";
lblScripter.Text = #"<script type=""text/javascript"">SP.SOD.executeOrDelayUntilScriptLoaded(function() {removeAllInfos();}, 'sp.js');</script>";
}
}
//else
//{
// lblScripter.Visible = false;
//}
}

Answer 1

Try to set :
lblScripter.Text = #"<script type=""text/javascript"">SP.SOD.executeOrDelayUntilScriptLoaded(function() {showInfo('" + MessageShow + "');}, 'sp.js');</script>"
Most likely this will solve your problem of calling the SP.UI.Status javascript functions before they have been loaded.

I Have solved this PFB code in order to acheive this. Thanks to my friend Hameed who has helped me to acheive the same
<script type="text/ecmascript" language="ecmascript">
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RegisterMethods);
function RegisterMethods() {
showInfo();

function showInfo() {
var strMessage = document.getElementById('<%= Message.ClientID %>').value;
var strstatus = document.getElementById('<%= StartStatus.ClientID %>').value;
if (strMessage != null) {
if (strstatus != "false") {
var strStatusID;
strStatusID = SP.UI.Status.addStatus(strMessage);
SP.UI.Status.setStatusPriColor(strStatusID, "red");
document.getElementById('<%= StartStatus.ClientID %>').value = "false";
