Databind ListView datasource and joined tables


Hi all.

I am not expert in ASP so i would be appreciated for the help. Issue connected to Entity FW, ListView Control, its Datasource and type convertion.

I have the  following LINQ query :


RoutesEntities routesModel = new RoutesEntities();
LocalesEntities localesModel = new LocalesEntities();
ObjectQuery routesQuery = (ObjectQuery) from routes in routesModel.Routes
                                                    join locales in localesModel.Locales
                                                    on routes.LocaleID equals locales.LocaleID

Both DataSource and DataSourceID are defined on 'ddlEvent'. Remove one definition


 Hi I have encountered the above error. I have read a couple of solution in this fourm and was not able to resolve it. here is my code

This page is called on load, to populate combo boxes of  the page.  when I comment this method, I am able to run the page, but when I uncomment the method, I get the above error.


I have search on both      ......  DataSource     and     DataSourceID  and was not able to find any code in my application to proof that I am using them in the apsx page ( front page ).  I only can see in the code behind like this method. .

One of the solution is to remove either one, but how can I remove when I do not see any in the front page. ( apsx )

please advise.


        private void Combo_Bind()
                ddlEvent.DataSource = select("usp_dbo_ASL_JV_Template_JVTemplateName_SELECT");


Both DataSource and DataSourceID are defined on 'GridView1'. Remove one definition.


I have a gridview defined in my aspx page having a DataSourceID="myDataSourceID".  I have a <asp:SqlDataSource ID="myDataSourceID ...</asp:SqlDataSource> on the same page.  The first time a user comes onto the page that is the datasource I want to use to load the gridview...I works no problems.

I also have some check boxes on the page in a CheckBoxList with OnSelectedIndexChanged="myCodeBehind".  In myCodeBehind I build a query using the values of the checkboxes (thanks akhhttar) and try to use the query in to bind data to the gridview...

        Dim SqlDataSource1 As New SqlDataSource
        SqlDataSource1.ConnectionString = "$ ConnectionStrings:startpagegridview1ConnectionString"
        SqlDataSource1.ProviderName = "$ ConnectionStrings:startpagegridview1ConnectionString.ProviderName"
        SqlDataSource1.SelectCommand = Query
        GridView1.DataSource = SqlDataSource1

Site builds and publishes ok, but at runtime...

GridView inline Master/Detail record display

This code drop is part of a smash and grab series. If you're in a rush, you can just grab this code and insert it into your application, no understanding is required. When you have some time (ya, right) you may want to review the source code.

Hide a repeater in ASP.NET C# if the DataSource contains no items?

I have an ASP.NET page that uses a repeater nested within another repeater to generate a listing of data. It's to the effect of the following:
In the (C#) code-behind I'm basically using LINQ to pull a listing of information from an XML document and bind that information to the first repeater.

Searching for the answer to this, it seems the method is to determine whether the data for the nested repeater is empty. If it is, then you set the visibility of the repeater to false.

Manually sorting and paging Gridview without using datasource control

Many a times while working with Gridview we want to work with the paging and sorting functionality without using any datasource control. Gridview is flexible enough to perform these tasks without the use of any datasource control and only a few lines of code.

Gridview Edit on Searching of Record


using Asp.net c#

sql server

i am searching a record from my database and displaying it in gridview now i want the comments should be updated as per the record which is being searched

For E.g if record No.3 is searched then only i can update record no.3 and i don't want rest of data to be shown

now what is happening when i click on edit my whole table is being displayed

this is bcuz i made one method gridfill() which i m calling everytime if i m doing grid row editing,row cancelling and row updating

how i can resolve this thing

my code

 protected void GridView2_RowEditing(object sender, GridViewEditEventArgs e)
        GridView2.EditIndex = e.NewEditIndex;


 protected void GridView2_RowUpdating(object sender, GridViewUpdateEventArgs e)
        string id = GridView2.Rows[e.RowIndex].Cells[0].Text;
        TextBox t;
        t = (TextBox)GridView2.Rows[e.RowIndex].Cells[2].Controls[0];
        string query = "update user1 set comments=@comments where id=@id";
        SqlConnection con = new SqlConnection(connstr);
        SqlCommand cmd = new SqlCommand(query, con);

Does this look correct for saving a file/ new record to a database


So thank you for all your help so far, So I think i got this right,
but would like for you all to look it over to see if there is any
areas I might run into trouble with:

//using asp.net mvc 2
the table (sql server 2005, using entities framework)
table fields
"Pattern_Media_GUID  uniqueid 
"Pattern_GUID  uniqueid
"Media varbinary(max)  
"height int
"Width int
"Media_Type String (50)

the form:
<h2> Add Media to this pattern</h2>
<% Html.EnableClientValidation(); %>
<% Html.BeginForm("AddMedia", "Pattern", new { id= Model.Pattern_Guid} , FormMethod.Post, new {enctype = "multipart/form-data"}); %>
    <%: Html.Label("height") %>
    <%: Html.TextBox("height") %>

    <%: Html.Label("width") %>
    <%: Html.TextBox("width") %>

    <%: Html.Label("Media") %>
    <input type="file" id="Media" name="Media" />

Remove #Region from whole web site


Hi All,

I need to deliver source code to client and my boss need to remove all the comments and #region sections from the whole web site source code.

So is there any functionality available in visual studio 2010 or may be in an other 3rd party tool available to do so, which can remove all the #region from all over the source code ?

Otherwise my developers has to do donkey work.... :(( and I don't wish it. 

Any help or tips/tricks would be appreciated.


Dynamic Data, Domain datasource, Poco and lookups


Mr. Edward,

Excuse my question but: it is necessary to involve in our projects something more than just Dynamic Data or should we make use of all other features available in VS2010 (which will make assume taht they had been left out of the Dynamic Data framework) like: wef, poco, azure, wcf, cloud, mvc, silverllight, ajax, odata, agile, workflow, etc.?

Sorry my ignorance, I'm just transcribing names as they come to my mind and of which I don't know anything about

Why show only one record?



// Update these variables to values whatever you are storing in your table
        // If you are storing as CARD NUMBER, update this Card Number Attribute Name to CARD NUMBER
        string strCardNumberAttributeName = "Credit card number";
       // string strCardTypeAttributeName = "1";
        string strExpiryDateAttributeName = "Expiry date";
        DataTable dtPaymentDetails = new DataTable();

        string queryString = "SELECT tbl_Payments.PaymentId, tbl_PaymentDetails.AttributeName, tbl_PaymentDetails.Value, tbl_Payments.PaymentType FROM tbl_Payments INNER JOIN tbl_PaymentDetails ON tbl_Payments.ID = tbl_PaymentDetails.PaymentId WHERE ATTRIBUTENAME IN ('" + strCardNumberAttributeName +
                                   "','" + strExpiryDateAttributeName + "') ORDER BY PaymentId";

        string connectionString = "data source=.\\SQLEXPRESS;Integrated Security=SSPI;" +
                                           "AttachDBFilename=|DataDirectory|\\BurnbetDatabase.mdf;User Instance=true";
        using (SqlConnection connection = new SqlConnection(connectionString))
            SqlCommand command = new SqlCommand(queryString, connection);
            SqlDataReader reader = command.ExecuteR

Can this code be setup to run against the whole database instead of just 1 record at a time?


We have made some changes to this code to start capturing 1 new field of data and updating it as new records are added. But there is currently about 120,000 records more or less.. those records of course dont have the new field populated with anything..

We would like to run this logic that already in place and run it against the tables to update the fields 1 time. I think to make it easier, if it can be setup to expect the "valueTwo" variable, so that we can run it againt the individual codes instead of doing all the records at one time.. there are codes that only have a few records, so it would be best to test initially against the small code group.


            strSqual = "insert into trans (trans_type_name, trans_date,sys_id,mod_user_id,show_ind, remoteCode, techName) values('" & valueTwo & "','" & TransDate & "',"&strSystemID&", 1,'T', '" & dbQuote(strUser) & "', '" & strTechName & "')"        
            'get the new transaction_id out for just inserted alarm   
            strSqual = "select max(transaction_id) as transaction_id from trans"  
            set rst = getStaticRecordSet(strSqual)

Querying a db for existence of a record.


Can someone suggest, what is the best approach using linq to sql to do the following

1. Check if a row exists in a table for a given criteria and...

2. If it exists return a particular field value else return '0'.
