To solve this, you would need to automatically detect whether a value is null and then add it to the Update Parameters list.

It can be used in combination with a Grid View control for master-detail scenarios.

Toolbox Data("The Details View control is used to display a single record from a data source in a table, where each field of the record is displayed in a row of the table.

Initializing the SQL data source also had another problem – because certain data needed to be re-encrypted before being sent back to the database.

You will need to single out any columns that need to be encrypted.

Each field is then displayed in a row as text, in the order in which each field appears in the data source.

Design, Version=2.0.0.0, Culture=neutral, Public Key Token=b03f5f7f11d50a3a", "System. Valid bindable types are String, Date Time, Decimal, Guid, and the set of primitive types.

Note: The Details View control can provide support for update, delete, insert, and paging operations with other types of data sources; however, you must provide the implementation for these operations in an appropriate event handler. Clicking the Update button updates the record in the data source, while clicking the Cancel button abandons any changes. You can customize the appearance of the Details View control by setting the style properties for different parts of the control.

Likewise, in insert mode, the New button is replaced with an Insert and a Cancel button, and empty input controls are displayed for the user to enter the values for the new record. The Details View control provides a paging feature, which allows the user to navigate to other records in the data source. The pager row can be customized using the Details View. The following table lists the style properties that you can set.

To String(); We can use the above code in the Data Bound event of the Detila View control to retrieve the Data Keys.

When the Details View control is bound to a data source control, the Details View control can take advantage of the data source control's capabilities and provide automatic updating, deleting, inserting, and paging functionality. Input controls that are appropriate for the field's data type (such as a Text Box or a Check Box control) are displayed with a field's value for the user to modify.

After doing this, we can retrieve the Data Key value in the following ways. So, we call Databind() method in the Page Index Changed event handler and then retrieve the datakey value as shown in the code given below.

  2. “I'm not a feminist as many people seem to interpret it which basically comes down to resenting men - I'm more of the opinion that you're only treated how you allow yourself to treated, and that women should know how they want to be treated and feel able to speak up for that.” Another female drinking group, MSLS, (profile picture: nuns, with the tagline, “All the single ladies”) rate a crewdate with the all-male “1923 Committee”: “Lads were quick to establish tough drinking rules but they unfortunately came off worse than us, also their pretence at laddiness disappeared as we impressively out-bantered them.” So it seems girls and guys rate each other with similar gusto.
