How to pass parameter to c# method calling in javascript.
My code is like this .
objTotalInclusive.value=TotalAmtInclu.toFixed(2);
objRoundOff.value= Math.round(TotalAmtInclu);
var wordsnum= objRoundOff.value;
var objwordstonum =document.getElementById('<%=lblNumSpelling.ClientID%>');
var objwords = '<%NumberToSpelling(''+ wordsnum+'')%>';
objwordstonum.value= objwords;
I have a textbox that I use to gather a date. I would like to have the database store a null if this field is left blank by the user when submitting. I am using the following on my aspx page:
<div class="col-md-3">
<strong>Date Submitted to TDI</strong><br />
<asp:TextBox ID="sub_tdi_dt" runat="server" Enabled="true"></asp:TextBox>
<asp:ImageButton ID="sub_tdi_dt_cal_popup" Enabled="false" ImageUrl="Images/calendar.png" ImageAlign="Bottom" runat="server" />
<ajaxToolkit:CalendarExtender runat="server" BehaviorID="sub_tdi_dt_CalendarExtender" PopupButtonID="sub_tdi_dt_cal_popup" TargetControlID="sub_tdi_dt" ID="sub_tdi_dt_CalendarExtender"></ajaxToolkit:CalendarExtender> </div>
I have tried using the following in Page_Load, but it doesn't work - I still get '1/1/1900':
DateTime? sub_tdi_dt = null;
I've just noticed I'm repeating a lot of C# code in my ASP.NET application so want to create a generic method. I have a series of private methods like this:
[Code]....
So, I want to replace DB.MyRepeatedCall, chtMyRepeatedChart and pass them in as parameters to a generic function. Is that possible? I have many charts on my form that take the same number of parameters.
UPDATE
Following Frederik's solution I have done this:
[Code]....
I am calling the function with this command:
PopulateControl (chtEquityCurve, DB.GetAccountBalances());
I get this error in the intellisense:
No overload for method 'GetAccountBalances' takes 0 arguments.
I have an ActionResult Method defined as following;

I am using JQuery and would like to know how I call this method passing a parameter. I have the following which does not work;

I have a web form and I use jQuery/AJAX/JASON to send objects to a web service using
$.ajax({
type: "POST",
url: "SynchroniseCustomers.asmx/synchroniseCustomers",
data: JSON.stringify(customerObj),
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, status) {},
success: function (msg) {}
});
From the web service I want to check if the insert into the database was successfull, return a variable with an ID and pass this ID to a function. In the object I have the ID so I could have
success: function (msg) {deleteCustomer(ID);}
But this only checks if the data was passed to my method in the web service? I have followed this example http://encosia.com/2009/04/07/using-complex-types-to-make-calling-services-less-complex/ and in the class Person I get a message back from the database server telling me if the insert was successfull or not so like
if (successfull)
{
return ID;
}
is there a way to get this ID back to the web form and use this in a variable?
can we pass dataset to a web service method? If yes , then how?

View 1 RepliesMy issue is similar to [URL] how-to-use-the-value-of-a-selected-value-from-a-dropdownlist-populated-with-ajax but I am using ASP.NET, not PHP. I have a dropdownlist that is populated by another dropdownlist's current value through ajax. So if DDL A is 'NY', DDL B is populated with different data relating to 'NY'. I need that data to be posted back to the server because this affects an SQLDataSource parameter. However, as far as I can tell, the value is always null after postback resulting in the gridview to be empty.
View 1 RepliesBasically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window. All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;
}
.NET Code-Behind
Protected Sub RadGridOnlineRequests_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridOnlineRequests.ItemCommand
If e.CommandName = "ViewOnlineRequest" Then
' populates LabelScheduleDate among other controls values
ScriptManager.RegisterStartupScript( _
Me, Me.GetType(), "clientScript", "RefreshParent(" & LabelScheduleDate.Text & ");", True)
End If
End Sub
I have the following:
<EditItemTemplate>
<asp:Button ID="wrqst_need_ind_btn" runat="server" Text = "Create WR"
onClientClick="javascript:popUp('popup_createWR.aspx')"
CommandArgument='<%# Eval("dvc_nm") + "|" + Eval("data_orgtn_yr") %>'/>
</EditItemTemplate>
I want to pass in as two additional params the Eval("dvc_nm") and Eval("data_orgtn_yr") to the popup function.
UPDATE:
I tried by removing the single quotes from insode the <% %> tags. Which gave me this:
onClientClick='<%# "javascript:popUp(popup_createWR.aspx," + Eval("dvc_nm") + "," + Eval("data_orgtn_yr") + ")" %>'
which complied, but when I clicked the button I did not get a pop up, the page just posted back and reloaded and said errors on page, but no popup...

I need to pass javascript function as a parameter value to the ajax actionlink in asp.net mvc app. how can we achieve this?
View 1 RepliesI remember being told that you can add some syntax to the end of a statement that will do something if the field is null. Pretty vague, but I cant seem to find anything about it via google.
I definitely isnt how to set a field to be nullable. I know that.
Here is an example of what I want.
int? field1 = 0;
field1 = int.parse(string2); (where string2 is a passed value, that could be null)
I thought there was something you could put at ?? if it is a null, such as:
field1 = int.parse(string2) ??;
Or do I have to check every if every string2 is null before making that statement.
Can anyone reliably get the EDS to save a nullable column to the databse as a "null" when bound to any of the controls such as "FormView"?I have tried using several different UpdateParameters (Session, ControlParamater, Parameter, etc). I have tried setting "ConvertEmptyStringToNull" to true and leaving the property off entirely. Nothing works. On my "Inserts" it works fine.(I have made sure the column is set to nullable = true in the Entity Designer.....)
View 7 RepliesI am calling a javascript function from .cs file which is as below:
private string CallValuesScript()
{
StringBuilder sb = new StringBuilder();
sb.AppendLine("$(document).ready(function() {");
sb.AppendLine("DisplayValues();");
sb.AppendLine(" });");
return sb.ToString();
}
I have two integers declared at class level private int ratingLinkId = 0 ;
private int ratingValue = 0;
how I can pass these two integer values to the function "DisplayValues();" ? I have the javascript function is aspx as below:
function DisplayRatings(id, count) {

My designer.cs file of all the SQL tables is generated by LINQ-TO-SQL. The class and attribute in question is like this.
[global::System.Data.Linq.Mapping.TableAttribute(Name="dbo.Transfers")]
public
partial
class
Transfer :INotifyPropertyChanging,[code]...
I need to assign a null to the attribute so that the value 0 does not get save to the database.
The C# code below:
int? i;
i = (true ? null : 0);
gives me the error:
Type of conditional expression cannot be determined because there is no implicit conversion between '<null>' and 'int' Shouldn't this be valid?
I have the following function signuture:
public JsonResult PopulateGrid(int page, Guid? accountId, Guid? systemUserId, Guid? branchId, DateTime? fromDate, DateTime? toDate, HomeVisitType? homeVisitType)
Every single parameter is bound just fine except toDate which turns out to be always null. When inspecting the Request.QueryString["toDate"] it retrives the right value which is 30/09/2010. It seems that DateTime expects another format when binding.
What is the right format?
Got a nullable datetime member on my viewmodel.the moment it hit my controller action, the viewmodel's modelstate allready are invalid (because the member is null).Forgot...how that works? (using MVC2)Basically my viewmodel have a social security number, passport number and passport expiracy date.If the ssn is entered, I want to ignore the two passport related fields, so I made the expiracy date member nullable.
Like all other viewmodels in this app, each model have it's own validation function that will do validation, and in there I add an error that the date is required or not valid (if using passport number). mvc itself should not care about the date at all.I dont want to give the date a default value, because then the date will show when the form loads, and it must be an empty field (unless I already got a date of course.
I'm calling PageMethod "SameMethod" from javascript method "caller" so that I can get some values from DB. After I get values, control is continuing in "onSuccess" method. Problem is that I need to use some variable values ("importantValue") from javascript method "caller" in "onSuccess" method.
function caller(){
var importantValue = 1984;
PageMethod.SomeMethod(param1,..., onSuccess, onFailure)
}
onSuccess method should be something like this:
function onSuccess(pageMethodReturnValue, importantValue ){
}
Is it possible and, if it is, how to pass multiple parameters (besides return values of page method) to "onSuccess" method of PageMethod?
