I have a series of record IDs in an array that I pass to a DataGrid for Data Binding I want to show the details of each record ID in every row of the datagrid, for example I can put a detailsview in the itemtemplate of the datagrid and use an objectdatasource's select method for retrieving the information for a specific record ID but how to pass these record IDs to objectdatasource? is this a correct example and how can I implement this?
View 3 RepliesI would like to ask if there is any control act like grid to display records.The 'datasource' will be a customed class, this dataclass has List<T>, so I will populate each element by iteration into the grid.Any control can I use to work like a grid?The number of records will around 100.This control should also allow the user to select a record.

I have followed an online Microsoft tutorial that walks through building a Northwind.xsd that includes ProductsTableAdapter and a few other such table adapters (http://msdn.microsoft.com/en-us/library/aa581776.aspx).
Question: I now see a update column at the start of each row of the datagrid for AllProducts page. When I click update on a row and change the value of one of the non-primary fields (ex. Productname) and press Update, I get the following error:
The GridView 'GridView1' fired event RowUpdating which wasn't handled. How do I implement this event handler in VB? I know that when I implement using SQLConnection and use templatefields to bind each column I don't need to implement each event handler.
I have take a datagrid view and now i want to update the records as the database is been normalized i need to enter the multiple rows at once. How you I convert the datagrid to enter the data so that it would be easy for me to update the records?

I want to update a record in a detailsview which contains a decimal value which I would like the field to formatted as currency while editing.
When I try to update the record I get an error about trying to pass a formatted value to an unformatted table column. The ApplyFormatInEditMode is set to true and you are cautioned by intellisense about unformatting befor updating the record. This is databound field.
Is this a simple as x = Val(detailsviewrow(1).tostring) ?

This morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.
I want to have a checkbox in a datagrid.
Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.
In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.
Also, I need to update a label in the page with a value associated with the row of the checked checkbox.
I should not be using a javascript to do this.
I have a Drop Down List, a GridView and a DetailsView. The Gridview is the master, the details is the records detail view. When we edit a record and click the update button, I want the page to refresh the gridview and detailsview. Right now after clicking the update, nothing happens, it just updates the current details record.

I have a web form with a detailsview controlled by a linkbutton in a gridview. When the user clicks the linkbutton, a panel appears with the detailsview inside it. The select statement is created based on the commandargument of the link button. So far, if there is a record associated with the ID passed through the linkbutton, the detailsview displays correctly. However, if the user needs to update this, it jumps to the default record for that detailsview after clicking the standard update link. Without a default ID set, the detailsview does not display at all, as some IDs do not yet have a corresponding record for the detailsview.
How can I get around this issue? Also - is there a way to immediately display an open detailsview for IDs with no record associated yet?
I am using ListView for the first time. I have a requirement that in a listview if I Edit a record and before clicking teh Edit button of tthis record if i click on the "Edit" button in other record, my first record should be saved and second record should open in Edit mode.
View 2 RepliesI am populating the gridview on the basis of listbox selection . However, I am setting the datasource in the click event after listbox entry. When i am trying to update any record in the gridview this error gets thrown because the datasourceid from the aspx page has been removed. Code for reference -
protected void btn_save_Click(object sender, EventArgs e)
{
ArrayList list = new ArrayList();
foreach (object o in ListBox2.Items)
{
list.Add(o);
}
string str2 = null, str, host;

host = Convert.ToString(list[0]);
str2 = " ( SYSTEMNAME like '" + host + "'";
for (int i = 1; i < list.Count; i++)
{
host = Convert.ToString(list[i]);
str2 = str2 + " or SYSTEMNAME LIKE'" + host + "'";
}
str = str1 + str2 + " )";
