Assuming this is really your first post, welcome to CP. We have subject lines in our posts so we can tell people what we want help with. Everyone here wants help with ASP.NET, although I agree that your problem appears to be that you have no idea at all. You're at the stage where you need to buy a book and work through it, not post random questions to the internet based on stuff you heard the programmers you work near ( I assume you're not a programmer at this point ), discuss over the water cooler.

Morning all,
My appologies in advance if i'm asking this in the wrong page - my train of thought was that most people in here would have a opinion.
Anyway.....i've started learning c# at university and all is going well (so far !!) and i increasingly see ASP.NET mentioned alongside.
Can anyone give me some advice as to a good book to pick up to start learning ASP.NET also.
I'v looked on Amazon and places like that and there are plenty to choose from, i just don't want to buy a book that i won't understand because it's too advanced so though i'd ask those that might know - you guys !
If it helps anyone - i've used the O'Reilly 'Head First' range and found them very helpful in the past.
Thanks in advance
Neil

Like i said Abhijit, i have already searched online bookstores, google etc -sometimes it better to ask people who have possibly been in the same situaton, or found a book that really 'worked' well.
Don't worry - i wasn't asking anyone to do any of the work FOR me. Mearly asked for an opinion.

Hi, I'm using crystal report, which is in vs 2005.

param1Field.ParameterFieldName = "pEmpCode"
param1Range.Value = ddlEmpCode.SelectedValue
param1Field.CurrentValues.Add(param1Range)param1Fileds.Add(param1Field)CrystalReportViewer1.ParameterFieldInfo = param1Fileds CrystalReportViewer1.ReportSource = "Reports\rptEmpDetails1.rpt" CrystalReportViewer1.RefreshReport()CrystalReportViewer1.Visible = True
If i use this, It is asking again the parameter value. Thanks in adv.

Hi! I am keep getting this error in my web application, here is what I am doing:
<pre> sqlDataSource sqlDataSource2 = new SqlDataSource();
sqlDataSource2.ID = "workoutScheduleDataSource";
Page.Controls.Add(sqlDataSource2);
sqlDataSource2.ConnectionString = WebConfigurationManager.ConnectionStrings["ClassScheduleConnString"].ConnectionString;
sqlDataSource2.SelectCommand = "SELECT Workout_Name, WorkoutType, MembersAttending, DateSelected, Explanation FROM WorkoutTable WHERE AddedBy = '" + user + "'";
gridviewWorkout.DataSource = sqlDataSource2;
gridviewWorkout.AutoGenerateSelectButton = true;
gridviewWorkout.DataBind();</pre>
when it gets to the last line gridviewWorkout.DataBind(), it gives me the error that: "A field or property with the name 'AddedBy' was not found on the selected data source." I am testing the query with SSMSE, at the same table, and it works just fine...but here I am getting error. Any help will be appreciated. Thx ahead, Laziale

In your binding in the markup, are you trying to bind a column called AddedBy, as it is not returned in your source.
|
|
|
|
|
here is what I have in my markup:
<pre> <asp:GridView ID="gridviewWorkout" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Workout Name" DataField="Workout_Name" />
<asp:BoundField HeaderText="Added By" DataField="AddedBy" />
<asp:BoundField HeaderText="Workout Type" DataField="WorkoutType" />
<asp:BoundField HeaderText="Members Attending" DataField="MembersAttending" />
<asp:BoundField HeaderText="Date" DataField="DateSelected" />
<asp:BoundField HeaderText="Explanation" DataField="Explanation" />
</Columns></pre>
within the DataField I have declared the columns as they are in my table in the database.
|
|
|
|
|
Yes, but your SQL statement does not actually return a column for the AddedBy, you just have it in your where clause.
|
|
|
|
|
I have this piece of code at another page within this project, and it works just fine:
<pre> SqlDataSource sqlDataSource1 = new SqlDataSource();
sqlDataSource1.ID = "trainingScheduledatasource";
Page.Controls.Add(sqlDataSource1);
sqlDataSource1.ConnectionString = WebConfigurationManager.ConnectionStrings["ClassScheduleConnString"].ConnectionString;
sqlDataSource1.SelectCommand = "SELECT Class_Name, ClassType, MembersAttending, Staff, DateSelected, Explanation FROM ClassSchedule WHERE AddedBy = '" + user + "'";
gridviewClass.DataSource = sqlDataSource1;
gridviewClass.AutoGenerateSelectButton = true;
gridviewClass.DataBind();</pre>
where is the difference? it looks same to me

That's very nice. You've said in your grid (in the markup), that you want to display data for a field called AddedBy.
When you bind the data, the grid goes and looks in your returned data for a field by that name. It's not there. Grid isn't happy and throws an error.
You need to put another field in your select statement for the first case, return the AddedBy field, or remove that column from the grid.
