help needed on ObjectDataSourc e control

[Manjunath]

HI,

How to catch custom exception using ObjectDataSourc e Control.
I am calling Business Layer method through ObjectDataSourc e control, when
Business layer method throws exception which will be wrapped to custom
exception and thrown. I want to capture the custom exception in UI Layer.

e.g.,
UI Layer Code:
protected void Page_Load(objec t sender, EventArgs e)
{
try
{
ObjectDataSourc e1.SelectMethod = "GetAllRole s";

ObjectDataSourc e1.TypeName =
"Shell.BizTalk. Services.BizDas hboard.Business Layer.RoleBL";
GridView1.DataS ourceID = "ObjectDataSour ce1";
GridView1.DataB ind();
}
catch (BizDashboardEx ception objBizDashboard Exception) // want to capture Here
{
string s1 = objBizDashboard Exception.error No;
BizDashboardExc eption.publish( objBizDashboard Exception);
}
catch (Exception ex)
{
string s = ex.InnerExcepti on.Message; // Always capture this exception
}
}

Business Layer Code:
public static roleData GetAllRoles()
{
roleData objRoleData = null;
try
{
int x = objRoleData.Tab les[0].Rows.Count;
}

catch (Exception objException) // Converting to Custom Exception
{
throw new BizDashboardExc eption("BSC-001", objException,
objException.Me ssage, "RoleBL-GetAllRoles", Severity.Warnin g);
}
return objRoleData;
}

Try handling the Selected event of your ObjectDataSourc e:

protected void ObjectData_Sele cted(object sender,
ObjectDataSourc eStatusEventArg s e)
{
BizDashboardExc eption ex = e.Exception as BizDashboardExc eption;
if (null != ex)
{
BizDashboardExc eption.publish( ex);
e.ExceptionHand led = true;
}
}

Also, unless you have a _really_ good reason, don't ever do

try
{
...
}
catch(System.Ex ception ex)
{
DoAbsolutelyNot hingWithExcepti on(ex);
}

or you won't find out that your app is broken until it's too late.

HI Flinky Wisty Pomm,

I tried the solution which u provided which is working fine, there is
small changes in the code as below

BizDashboardExc eption ex = e.Exception.Inn erException as
BizDashboardExc eption;

if (null != ex)
{
BizDashboardExc eption.publish( ex);
e.ExceptionHand led = true;
}
