I have one button in the grid view it ios called Edit and when the person clicks that item in the row it gives the user an option to either update or cancel the information entered in the row. Text = "No Company Found." End If lbl Work Order ID. Close() End Using End Sub Protected Sub Grid View1_Row Editing(sender As Object, e As Grid View Edit Event Args) Handles Grid View1.

This is the HTML code:                                                                                                   Imports System. Text = Session("ID") If Not Is DBNull(Session("City")) Then lbl Company City. Text = "No City Found." End If If Not Is DBNull(Session("Address")) Then lbl Company Address.

Introduction Step 1: Replicating the Example from "Tutorial 17: Examining the Events Associated with Inserting, Updating, and Deleting" Step 2: Converting the Bound Fields into Template Fields Step 3: Adding the Validation Controls to the Grid View's Edit Item Templates Step 4: Summarizing Data-Entry Problems Step 5: Adding the Validation Controls to the Details View's Insert Item Template Step 6: Partitioning the Validation Controls into Validation Groups Conclusion The Grid View and Details View controls in the examples we've explored over the past three tutorials have all been composed of Bound Fields and Check Box Fields (the field types automatically added by Microsoft Visual Studio when binding a Grid View or Details View to a data source control through the smart tag).

When editing a row in a Grid View or Details View, those Bound Fields that are not read-only are converted into textboxes, from which the end user can modify the existing data. New Edit Index ' Execute Non Query("Update tbl Work Order Item Set Note='' Where Work Order Item ID=" & Convert. Close() Bind_Data() End Using Catch ex As Exception End Try End Sub Protected Sub Grid View1_Row Canceling Edit(sender As Object, e As Grid View Cancel Edit Event Args) Handles Grid View1. Edit Index = -1 End Sub Protected Sub Grid View1_Row Updating(sender As Object, e As Grid View Update Event Args) Handles Grid View1. Edit Index = -1 Dim str Note As String = Direct Cast(Grid View1. Note='" & str Note & "' Where Work Order Item ID=" & Convert.In Tutorial 17: Examining the Events Associated with Inserting, Updating, and Deleting, we created a page that listed the names and prices of the products in an editable Grid View.Additionally, the page included a Details View whose Default Mode property was set to Insert, thereby always rendering in insert mode.In this tutorial, we'll see how easy it is to add validation controls to the Template Field's Edit Item Template and Insert Item Template to provide a more foolproof user interface.Specifically, this tutorial takes the example created in Tutorial 17: Examining the Events Associated with Inserting, Updating, and Deleting and augments the editing and inserting interfaces to include appropriate validation.In particular, our validation logic will: Before we can look at augmenting the previous example to include validation, we first need to replicate the example from the Data Modification page to the page for this tutorial, To accomplish this, we need to copy over both the Data Modification page's declarative markup and its source code.First, copy over the declarative markup by performing the following steps: To copy over the source code, open the Data Modification cs page and copy just the text within the Edit Insert Delete_Data Modification Events class.Copy the three event handlers (Page_Load, Grid View1_Row Updating, and Object Data Source1_Inserting), but do not copy the class declaration or using statements.
