Now I need to make all the data editable (add, update, delete). Why isn't the Gridview the same as DataGridView? With the DGV, the data showed EXACTLY as it did in the database and one could add a record, edit a record, or delete a record.
I'm using the SqlBulkCopy within my asp.net C# web form. I'm able to upload my excel file, but if the first row has any blank cells in it, that colum does not upload, I was wondering if anyone had any luck in looking for NULL/Blank cells and if so how did you handle them for the insert into the database?
View 6 RepliesI am confused by some behaviour I am experiencing when I use the SqlBulkCopy command.I have two tables in my SQL server database that I use to upload 2 tables of data from an excel workbook. The primary key of each table is customer account number, the first table being a table of accounts, the second being a table of details with the account number linking the 2 tables creating a one-to-one relationship.The bulk copy works a treat apart from one rather problematic situation I have found when performing error handling. If I put an account into the details table that does not appear in the customer table, instead of causing key violation errors it still adds the entry - I was under the impression that this was impossible?
If I go edit the entry using SQL Server management studio, I cannot change account numbers to anything that does not exist in the other table thus showing that the relationship exists and works when using standard update SQL.Does anyone have any idea why and how data that violates key violations is allowed through when I use SqlBulkCopy?

Has anyone experienced this and how to fix this or how do I change the timeout so I dont get this error?

I have a customized data import executable in .NET 3.5 which the SqlBulkCopy to basically do faster inserts on large amounts of data. The app basically takes an input file, massages the data and bulk uploads it into a SQL Server 2000. It was written by a consultant who was building it with a SQL 2008 database environment. Would that env difference be causing this? SQL 2000 does have the bcp utility which is what BulkCopy is based on. So, When we ran this, it triggered a Deadlock error.
Error details: Transaction (Process ID 58) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I've tried numerous ways to try to resolve it. like temporarily setting the connection string variable MultipleActiveResultSets=true, which wasn't ideal, but it still gives a Deadlock error. I also made sure it wasn't a connection time out problem. here's the function.

As far as I understand UpdatePanels, they should be invalidated separately, i.e. triggerring one UpdatePanel should not touch the controls of the other panel. It does work so for controls outside of any UpdatePanels, however those which are inside ANY UpdatePanel are touched by triggering ANY UpdatePanel:
<form id="form1" runat="server">
<asp:ScriptManager ID="SM1" runat="server"/>
<div>

I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:

I have a table of data from which I am trying to delete a single row using jQuery. While I am having no problems getting a POST delete to work, Iam having issues getting the partial view to update properly to reflect the deleted data.The table resides in a strongly-typed view, Errors.ascx, which is called in my Index.aspx page. Errors.ascx is nothing special, just a table where each row has a delete button that looks like this:
public ActionResult Delete(Guid id)
when i using timer on update panel it current.rating values = null
Why ?
I have 2 updatepanel UpdatePanel1 and UpdatePanel2. Intialy updatepanel2 is invisible. In updatepanel1 there is a dropdown list, whose Selected Index Method change makes UpdatePanel2 visible.The code
UpdatePanel2.visible =true;
seems to run without any error, but updatepanel2 is not visible on the page. Is there anyway to make it work.
For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?
I am creating a database frontend in aspx/C# using LINQ to MSSQL. It has two pages: a main page which lists all of the records, and a page that appears when the user click the "Edit" button next to one of the list items for the user to edit a record.The database table has about 70 user-editable fields. I need to make the edit page, allowing the user to update/insert records. There are a couple ways I can think of make an edit page:Using a LinqDataSource and FormViewUsing a LinqDataSource and DetailsViewManually retrieve the value for each field and set the value for each field directly from Linq (e.g. "projectIDLabel.Text = Convert.ToString(thisRecord.Project_ID)"What would be the best way to design this?
