I am using Asp.net 3.5 listview control. In item_updating event I am using this code...
dim country as string = Dim country As String = e.NewValues("country_name").ToString.Replace(" ", "")

I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?
View 7 RepliesI'm using ADO.Net code to access and update the data from the database. I'm using GridView for presentation. I wish to preserve old values of all the columns while updaing the records.
I'm using Code behind and not d Data Source controls. I wish to list the old records once record is updated.
I am working with a formview edititemtemplate. Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values. These dropdown values get binded during page load. I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.
I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback. I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render. I'm just not sure how to get the stars aligned here. The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender. However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.

View 1 RepliesI have a repeater that I have bound to a sql reader via my code behind page.
However I can't figure out how to populate the controls in my repeater in my code behind code.
At the moment I am having to specify the database field e.g productprice with the control in the .aspx page like this
<asp:Label ID="LabelUnitPrice" runat="server" Text='<%# Eval("productprice") %>'></asp:Label>
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?

View 1 RepliesUpdates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.

View 2 RepliesScenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I need to get data from all rows which are selected (check box enabled). Can anyone give me hint? I am killing myself for last 10 houres with this.
What i need to say is that datasource is xml file
I have a grid view and I added edit and Save buttons to it. When I click on edit I am able to edit the data but when I click on save I amgetting the data before edit.Please see my code below.Eg: I have start date as 2005-10-10 12:00 AM so After I click On edit it is letting me to edit, So If I edit the start date to 2010-10-10 12:00 PM and click on the save button I am stil getting the old start date. which is 2005-10-10 12:00 AM instead of 2010-10-10 12:00 PM

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

How to Retain old values on updating with Stored Procedure
View 6 RepliesI have a SQL query I'm running in an ASP.NET page. The final parsed SQL needs to contain a list of string values in the WHERE [columnname] IN [values] format. For example, the final query might look something like this:
SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN ('ABC','DEF','GHI','JKL', /* etc */);
However, the string values in the WHERE clause need to be dynamic. Normally I use parametrized queries to make my code convenient and safe, so conceptually I'd like to do something like this:
String[] productCodes = { "ABC", "DEF", "GHI", "JKL" };
SqlCommand cmd = "SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN (@ProductCodes)";
cmd.Parameters.Add("@ProductCodes", productCodes);
However, this sort of functionality doesn't appear to exist in .NET. How should I go about implementing this? I could use a foreach loop on the array and run a query with a single value as a parameter for each value, but there could potentially be a hundred or so different values in the array and it seems like querying them separately would be very inefficient.
I've read another question where someone suggested a solution for strongly-typed int parameters, but that method would make me nervous about SQL injection when used with String values, especially since the client may very well be able to influence the input values.
How would you implement this query functionality?
EDIT with DB Details:
The database is SQL Server 2005.
