Deleting formatted record returns "Input string was not in correct format"

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net

I have a bound data field, a detailsview, one of the records I have formatted to currency in the item template. Yet when I go to delete a record, I get a error message "Input string was not in correct format". Take away the formatting and the page runs fine. I tried changing the datatype from int to money, it makes no difference. Ideas?

Need help on Refreshing grid after deleting a record


I have a form that when I click the delete button I want it to refresh the grid with that record removed from the grid. Does anyone know how to do this. Is this something handled in the code behind? Here is my code for the delete button on the design page:


<asp:button id="deleteButton" CommandName="Delete" 
                    style="background-image:url('Images/Button.gif'); text-align:center;background-color:Transparent; cursor:hand; background-repeat:no-repeat; background-position:left; padding-left:15px;" 
                    Runat="server" Height="25px" BorderStyle=None  ForeColor=White   Text="Delete" 
                    Width="99px" CssClass="style3" onclientclick="return confirm('Are you surely want to delete this record?');"  />


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.

Get Top 1 Record from Dataset

Many of them in need of getting the Top 1 or Top 10 records from a Dataset without going to SQL query. It is possible to do from Code Behind. I have given the code below,
The below code is to get single record from a Dataset. Also I have given for getting 8 records at Green Color.

Adding Client-Side Confirmation When Deleting

The JavaScript confirm(string) function displays its string input parameter as the text inside a modal dialog box that comes equipped with two buttons - OK and Cancel (see Figure 1). The confirm(string) function returns a Boolean value depending on what button is clicked (true, if the user clicks OK, and false if they click Cancel).

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

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" />
    <input type="submit" name=

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'.

Need Help in LINQ query for group By with chunks of record


I am assigning and unique id [strShipperIdSequence] on my List on bases of some properties which are grouped together uniquely.
Now what i needed is that my group should be further break down to some maximum amount of chunks.[Let say 10]
that mean's even i am having Same value in 12 records i should get 2 groups[I of 10 items and other of 2 items]

var uniqueGroups = objMdbContentInfoList.GroupBy(p => new
}).Select(g => g.First()).ToList();
foreach (var objUnique in uniqueGroups)
string strShipperIdSequence = APIGlobalMethods.GetShipperRequestID();
foreach (MdbContentInfo obj in objMdbContentInfoList.FindAll(h => (h.CON_ENTRY_POINT == objUnique.CON_ENTRY_POINT &&

Passing Primary Key to User Control to Display Record Detail


I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).

I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.

In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

        UserControlContactDetail.ContactId = "1462"
        test.Text = UserControlContactDetail.ContactId
