Hi, sorry if this seems stupid but I'm a newbie please have a little patience.
I've the following dataset code bound to my gridview
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:NwindConnectionString %>"
selectcommand="SELECT p.ProductID, p.ProductName, p.CategoryID, c.CategoryName FROM Products p inner join Categories c on p.CategoryID = c.CategoryID"
updatecommand="Update Products Set ProductID=@ProductID, ProductName=@ProductName, CategoryID=@CategoryID where ProductID=@ProductID"
deletecommand="delete from products where productid=@productid">
<deleteparameters>
<asp:parameter name="productID" type="Int32">
How can check if a value in a gridview cell already exist in the database?, I use the following to check if the value entered for "ProductName" is null, but I also want to check if the value entered does in fact already exist in my database.
Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridView1.RowUpdating
If e.NewValues("ProductName") = "" Then
e.Cancel = True
Return
End If
End Sub
Thanks and best regards.

IMO, the simple way is to execute a query against the current DB to see if this new value already exists or not.

|
|
|
|
can you give me a quick sample?
|
|
|
|
|
You simply use the ADO.NET's basic objects like SqlCommand, SqlConnection ... to execute a simple query like "Select count(*) from Products where ProductName=@ProductName" in the event handler and check the return value. Since this sample code can be easily found out there, so I may refer you to a link instead:

In ASP.NET 2.0,by Default, the Compiled Version of your Web Application (.dll file) is not stored in the 'Bin' directory of ur Application Folder like Older Version.
Also it will not stroed in the same name of your Web Application. It may be stored in some Temporary Folder, with a Random name ( xxxx.dll).

Jay

The compiling model is changed in the ASP.NET 2.0, and like someone said your source files by default are dynamically compiled to the assemblies stored in the temp folder of your ASP.NET application. I may refer you to a couple of links that can give you more information.

Codebehind and Compilation in ASP.NET 2.0[^]
Also, if you want to have the output assembly of the project generated in the Bin folder, you may use the Web Project 2005[^]

I want to run a vb script at a specified time. (this time comes from one of the table in the database)
i am using sql server.
How can i do this?
thanks

Hi there,
With the client side script, you may have a look at some methods setTimeout/setInterval to create a timer at the client side, these methods takes the time period (milisenconds) as the method paremeter, but I can guess that you are able to populate this value based on the time coming from DB.

Hi All,
I create 2 controls dynamically - one textbox and one "Add" button.These controls are present in 2 different groups.If I click the button it should add a textbox to the textbox group. I need to create the textboxes based on the button click.
Any help would be appreciated.

When you dynamically add the "Add" button, you can also add the event handler for the Click event to add the textbox at runtime. And you need to be careful when working with the dynamic controls as there two common mistakes that you may see: the dynamic controls get lost and the postback events do not execute.

Do you mean you want to determine which button is firing the event? and you might want to do that at the client side or the server side?

Not sure about what your code is doing, but IMO you can simply refresh the control with the data in DB after you delete the row. In other words, you can have put your code somewhere else to set the control value, and this basically happens after the row is deleted.
