Gridview values not updating
When clicked, a postback ensues and the Grid View s property is updated to the index of the row whose Select button was clicked.
In this tutorial and the next two we'll examine how to enhance the Grid View s functionality to include additional features.The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.To persist the check box checked status I have tried a custom implementation in this tutorial: Boxes_While_Paging_in_a_Grid View_I want to count the number of checkboxes which are checked on my page and if the count = 5 then to change the button state from disabled to enabled, but when I change page in Gridview are not counted the selected rows of the grid in previous page. I would greatly appreciate any help you can give me in working this problem. AFAICU above piece of code is for maintaining the state of selected checkboxes while paging.. In situations where the user can potentially select multiple records such as in a web-based email application, where a user might want to select multiple messages to delete the checkbox offers functionality that is not available from the Select button or radio button user interfaces.
This tutorial looks at how to add a column of radio buttons to the Grid View. Before we start enhancing the Grid View to include a column of radio buttons, let s first take a moment to create the ASP.
The example shown here is for a Grid View, but the same types of event handlers must be implemented in roughly the same way for other data controls including the Form View, Details View, and List View. This is the final Grid View markup, so you can see the event handlers we’re going to implement.
We’ll start with binding data to the Grid View, then build up functionality from there.
The required actions for paging to work are setting the new page index, setting the Data Source, and calling Data Bind (the last two through the Bind Data method).
In addition to that, we’re resetting the Edit Index and Selected Index when the page is changed to avoid cases, for example, where you change pages and are suddenly editing a different item.
We’ll revisit this method when we implement the sorting functionality.
