Rad Grid View can display data in bound mode, unbound mode and virtual mode. Grid View Row Cancel Event Args) Handles Rad Grid View1. Add(data Row View) End If Next i End Sub Private Sub rad Grid View1_User Deleted Row(By Val sender As Object, By Val e As Telerik. The bound mode is suitable for managing data using automatic interaction with the data store. Grid View Row Event Args e) Private last Removed Rows As New List(Of Data Row View)() Private Sub rad Grid View1_User Deleting Row(By Val sender As Object, By Val e As Telerik.
The following diagram depicts the sorting workflow, including the Grid View's assignment of its properties.For more information on sorting with the Grid View, along with a downloadable demo, check out the Paging and Sorting Report Data tutorial.When I implemented the up and down arrow images for the Data Grid control in Part 18 of the An Extensive Examination of the Data Grid Web Control article series, I put the code that added (or removed) the arrow images in the ASP. Specifically, the code enumerated the Data Grid's properties.Some applications may require updating the data base when the end-user is up to exit the applications. Current If current Is Not Nothing Then Edit Row = (CType(current, Data Row View)). In other cases the end-user may be required to click a special button in order to update the database. Row End If End Sub Private Sub employees Binding Source_Current Changed(By Val sender As Object, By Val e As Event Args) Dim data Row As Data Row = (CType((CType(sender, Binding Source)). Row If last Edit Row Is Not Nothing And Also last Edit Row. While the Data Grid (and Grid View) offer built-in sorting support, there is no visual feedback as to what column the data is sorted by.
In Part 18 of the An Extensive Examination of the Data Grid Web Control article series, I showed how to dynamically update a sortable Data Grid's header columns so that an up or down arrow image would appear next to the sorted column name depending on whether the column was sorted ascendingly or descendingly (view a live demo).This was accomplished by programmatically looping through the Data Grid's I recently needed to implement this functionality in a Grid View control. NET page, like I did with the Data Grid demo, I decided to instead create a custom Web server control that extended the Grid View control, adding the necessary functionality. If the Grid View is bound to a data source control that supports sorting, the Grid View will internally re-bind to the data source using the new sort order.In this article we will look at the steps for building such a custom control as well as how to use the control in an ASP. The custom control's complete source code and a demo application are available for download at the end of this article. If you have programmatically bound data to the Grid View, then you will need to create an event handler for the property is toggled.In the following sample scenario we are going to demonstrate how the implementation can be achieved. NET Data Table that loads its data from a component is bound to Rad Grid View control. This approach allows us to update the database when the end-user changes the current row in Rad Grid View. Clear() End Sub Private Sub rad Grid View1_User Added Row(By Val sender As Object, By Val e As Telerik.
