im currently doing a web form that shows will show the contents of a table from a database... the problem is that the codes im using only shows the data from the 1st row of the table and i need the data from all the rows of the tables
using System;
using System.Data;
using System.Configuration; [code].....
I have been trying to make this work for a while, but I have not been yet able to figure this put. I am using VS 2008 and mysql database. I wrote a query and checked to see if it works in database. It does.
I have a gridview, whose select command is that query. But for some reason, I just get all the rows from one table only. I rechecked my datasource and it is ok. I read on some discussions that it is NOT possible to have data from two tables in a gridview. Is that true? If that is not true, how can I have data from multiple tables in a gridview? Or any other web control for that matter.
have table COLLECTIONS and table CLOTHES.As an example, when showing the items on Listview, collection HAWAII
would be written on the top, and its texts and images on the itemTemplate.Then, collection WINTER and its texts and images on the itemTemplate.And so on.P.S: I´m connecting the Listview visually thru SQLDataSource, not programatically.How can i do it ? On the layout template using a JOIN on the SQL Statement ?
I found code [URL] that allows multiple-row inserts, and tried to convert it to vb.net. I can't get the blank grid with 5 rows to show up -- for some reason the datasource won't bind.

View 4 RepliesOn a page of my project, i have a gridview, i need to perform following operations with it:
1. On Page_Load i want to bind all the data (100 Rows) with the gridview.
2. On my Page i want to show only 4 records with Show More/Show Less Links.
3. When user clicks on the link, i want to show All data or 4 Rows accoeding to the link.
4. I don't want any roundTrip to the server, so plz don't suggest AJAX, i want to attain this by using Javascript.
I am trying to show the footer template of a gridview on page load when there is no data in the database. The reason why im saying page load is that I have code to actually pull data from the database instead of a datasource.
View 15 RepliesI am looking at building a grouping gridview, which I will know, will suit my needs. Therefore, I am not looking for a nested gridview. My answer is based upon an example I found at [URL]
However, what I am looking to do is to add a button to the group header row, which when pressed the rows within the group can either be shown or hidden.
I seem to be running into an issue where my Grid-view doesn't display any rows when the number of items is less the page size (in this case 10), I'm using the object data source and at times it can return 1 or 7 for the number of items function call, which cause the grid view to not display anything at all. If I change the page size to 1 or 7 then the results will show.
View 1 RepliesThe problem is I had to create a draftResult class in order to show data that resides in two different tables using linq which means if i want to add or remove a column i will need to do so in the draftresult and in my linq. Here's what my setup looks like: I have two tables (draft, lookUpStatus)
draft table columns
idname,status id
lookupStatus
idtitle
public class draftResult {
public string draftName {get; set;}
public string status {get; set;}
}
I want to list the draft name and the status title in a table view. In order to do this, I wrote the following linq in a method in my sqlRepository class and return it to a IQueryable<draftResult>. My controller instanstiates the sqlRepository object and invokes GetDraftListing().
public class sqlRepository {
private Table<Draft> _draft;
private Table<LookUpStatus> _lookupubStatus;
public IQueryable<draftResult> GetDrafLtisting() {
return (from draft in _draft
join status in _lookuptatus
on draft.StatusID equals status.ID
select new draftResult
{
draftName = draft.name,
status = status.Title
});
}
}
The above process works but does not seem as flexible and i'm trying to get a better understanding of MVC and LINQ.
I need to copy rows for 2 tables from one db to another.I want to be able to do identity insert, one way is to change the column to not be PK.if I mark the pk not a pk but just a column, can I still map it as an ID?

I am accessing rows in an SQL database table based upon the contents of the Primary key and another column. But, I cannot insert new rows in the table when the content of the new Primary key column already exists in another row. Can I define the table with a multiple column Primary key so that a unique value can be based upon the content of both columns?
View 3 RepliesI have a problem where I would like to get a comma-separated list of items from a couple of tables as part of a set of results. All the searching I've done so far has produced results for dealing with one or two tables. I have four, and can't get my head around how to adapt the sql to deal with it.
I have the following layout:
*Table_Castings*
+---- CastingID {PK}
| MouldID
| SerialNo
| CastRef
| MeltCode
| Signature
|
|
| *Table_CastCertificates* *Table_Certificates*
| CertificateID {PK} ----------- CertificateID {PK}
+---- CastingID {PK} Description
FileID -----------------+
|
|
*Table_CertificateFiles* |
FileID {PK} -------------+
FullLocation
The results I would like include the following columns:
CastingID, MouldID, SerialNo, CastRef, MeltCode, [Certificates],
Where Certificates is a comma separated list of Description + " " + FullLocation records. (What I'll actually do is add http:// and other html codes to make FullLocation a hyperlink, but I can do that.)
Some SQL I've already got is this:
DECLARE @str VARCHAR(500)
SELECT @str = COALESCE(@str + ', ','') + '<a href="http://' + Table_CertificateFiles.FullLocation + '">' + Table_Certificates.Description + '</a>'
FROM Table_CastCertificates INNER JOIN
Table_Certificates ON Table_CastCertificates.CertificateID = Table_Certificates.CertificateID INNER JOIN
Table_CertificateFiles ON Table_CastCertificates.FileID = Table_CertificateFiles.FileID
WHERE (CastingID = 45)
SELECT output = @str
This actually gives all records in the for the specific casting, but I keep getting an error at the "=" in @str = COALESCE when I try joining it to another query to get each casting.

View 2 RepliesI create an one webpage in asp.net all the time i am facing the following pbm how to rectify it..
if(ds.Tables[0].Rows.Count > 0)
I have 5 tables as follows
as it can be seen from diagram, I have one table ie.patientdetails with Pid as primary key and other 4 tables have pid which is foreign key related to Pid in patient details.
the problem is that when if a test data is filled for say patient with Pid as 1, the data is saved nicely in required tables
If i try doing that again for same patient then a duplicate is created in test tables with pid as 1.
Im having a go at doing a report for my asp.net application. I have 2 tables, one which lists a loan we have given to a customer, and another table which lists repayments against the loans.
I want to display each loan and how much is outstanding against it. My problem is that each loan is repeated in the table for each repayment against it. So when i try to sum up the loans awarded to a customer, if they only have one loan and have made 3 repayments against it, it sums up the amount awarded against each record.
eg, if i award a customer a loan of £200, and they make 3 repayments of £50, 3 records appear in the table. The amount awarded is repeated against each repayment, and when i total a customers loan amounts, it totals 3 x £200.
I have put the details into the grouping row, where it is grouped by loan_id, displaying the toal of repayments instead of each repayment. This stops it repeating in the table, but when i total the amount awarded field it still calculates 3 x £200.
I tried calculating the total on the report item after grouping but you cannot calculate on a report item.
Is there a way to stop the table from repeating the amount awarded against each repayment? Or even a way in the SQL statement of the dataset to make it display a total of repayments rather than each repayment. Cant see how to calculate a total repaid as i would need to pass a Loan_id in as a parameter.
I am using asp.net2.0 , C#. I am binding menu control with sitemap to display menus and submenues. Which also restrict access and display of menu or submenu based on user's roles. I want to know Is it Possible to show/ Hide submenu based on sql tables with existing sitemap method
View 1 RepliesMaybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.
The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work
So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.
Please helpe with this.
PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??
I am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."
The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?
I am creating a table in my code behind and I was wondering how I could show only the top border of each row?
