I am using stored procedure with RAISERROR. The error raised by the SP is not caught by the try catch statement in c#.Net. I'm using SqlDataSource for SQL connection and SqlDataSource_Updating event to update the data.
SQL Code:
DECLARE @count int
@count=0
if(@count = 0)
begin
RAISERROR('Updation failed. record already exists', 16, 1)
end
c# Code:
protected void sqlDataSource_Updating(object sender, SqlDataSourceCommandEventArgs e)
{
try
{
// Assigns the update command parameter
e.Command.Parameters.Add(new SqlParameter("@fag", Flg));
e.Command.Parameters.Add(new SqlParameter("@Date", DateTime.Now));
}
//catch (SqlException ex)
//{
//}
catch (Exception ex)
{
// If so, checks the Exception message
if (ex.Message == "Updation failed. record Not exists")
{
// Display the details of the exception to the user
lblMessage.Text = " record already exists";
}
// Writes the error in log file
WriteErrorLog(ex.Message , "sqlDataSource_Updating");
}
}
SQLDataSource:
SelectCommand="SELECT [ID], [Name], [Flg] FROM [Master] ORDER BY Name "
InsertCommand="exec [Master_Insert] @ID, @Name, @Flg, @createdDate, @createdBy, @updatedDate, @updatedBy"
UpdateCommand="exec [Master_Update] @ID, @Name, @Flg, @updatedDate, @updatedBy"
DeleteCommand="DELETE FROM Master WHERE ID = @ID"
oninserted="sqlDataSource_Inserted"
oninserting="sqlDataSource_Inserting"
onupdated="sqlDataSource_Updated"
onupdating="sqlDataSource_Updating">
</asp:sqldatasource>

The Updating event is used to customize the SqlCommand being executed, but it does not execute the command. The try/catch block must wrap the actual place where the command is executed, not the customization callback.
我立即注意到的一件事是您的存储过程正在引发“更新失败。 记录已存在 ”的错误消息与文本字符串“更新失败。 记录不存在 ”不匹配,您正在检查try / catch块。
Thank You for all your replies.
By using a e.Exception in sqlDataSource_Updated my problem got solved.
protected void sqlDataSource_Updated(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.Exception != null)
{
// If so, checks the Exception message
if (e.Exception.Message == "record already exists")
{
}
}
}
