can datatable pass to web service as input parameter? i have a scenario to pass values as datatable to web service. eg as follows
when Invoice or Bill is entered, I want to send the entered data as datatable to web service to insert into another application.
I Have Create the webMethod
Service:
[WebMethod]
public void GetCommission(List <BOLibrary.Flight.DTContract>Loc)
{
}
At the client side i am Passing the parameter Client
List<BOLibrary.Flight.DTContract> BoList = new List<BOLibrary.Flight.DTContract>();
BOLibrary.Flight.DTContract dtConboj = new BOLibrary.Flight.DTContract();
dtConboj.ValidatingCarrier = "AA";
BoList.Add(dtConboj);
BOLibrary.Flight.DTContract[] pass = BoList.ToArray();
service.GetCommission(pass);
But the Problem is that the service.GetCommission(pass) accpect the argument of servicenameSpace.DTContract but in client in client i have BOLibrary.Flight.DTContract so how can i pass the parameter to the to the Service.
I have a simple web method written in the code-behind (not a separate asmx) of a test aspx page.
All it does is return a DataTable(or DataSet) both are failing, gives a blank 500 error saying "There was an error processing the request"
If I switch the return variable type to String, it works fine
I think my issue has to do with the version of the System.Web.Extensions, is that the assembly that actually contains the JSON communication implementation?
I've read all kinds of tutorials about how it should be possible to return the DataTable to javascript and then read the properties with javascript syntax.
For some reason it isn't working for me.
My web extensions is imported through my web.config with the following version
<add
assembly="System.Web.Extensions,
Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
I am using the webservice method of populating my radtreeview as it was described as the most efficient way to load large amounts of data. So the signature of my webservice method is:
[WebMethod]
public RadTreeNodeData[] WebServiceMethodName(RadTreeNodeData node, object context)
However, the nodes that I am populating the tree with depend on the security access of the user that is logged in to my application..Is it possible to pass additional parameters to the webservice method? Or must I use a ServerSideCallBack method to populate the tree? I am hoping that I can still use the webservices functionality... I would like to pass a signature like this to my webservice method:
[WebMethod]
public RadTreeNodeData[] WebServiceMethodName(RadTreeNodeData node, object context, object userSession)
I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).

i am using vb.net 2008 i need to know about datagridview ......Is it to possible to add a data through vbcode in datagridview without using any datatable or dataset....
View 1 RepliesI am using VS 2008.I am building a datatable of records to be inserted into a SQL Server 2005 table.
The program loops through this table and builds a SqlParameter for each DataColumn in the datatable. The SqlParameters are used in the SQL Insert statement.
The field I am having a problem with is of type 'bit' in the database table and has no default value and cannot be nulls. The field is called 'Active' The meaning of this field in the application is Boolean i.e True or False. When inserting the record, I wish to default the field to "False".
When I define the columns in the datatable I am forced to use the following code to build the datatcolumn containing the boolean field i.e. dtcActive.DataType = GetType(Boolean) as there is no GetType(Bit)
Dim dtcActive As New DataColumn("Active")
dtcActive.DataType = GetType(Boolean)
dtcActive.Unique = False
dtcActive.AllowDBNull = False
dtcActive.DefaultValue = False
dtProviderDayDetails.Columns.Add(dtcActive)
However, when I build the SqlParameter I am forced to use this:
If field.ColumnName = "Active" Then
prm.SqlDbType = SqlDbType.Bit
prm.Value = "False"
End If
This is because there is no SqlDbType.Boolean. The problem I have is there is no value I have been able to give the SqlParameter that is accepted by the Insert statement. It complains that the boolean field cannot be null on Insert.
