Asp net gridview onrowupdating

asp net gridview onrowupdating-49

From some googling it appears that, at least in the release candidate for NET2 this was a known bug; only binding to Data Sources lets those dictionaries be populated. | | From some googling it appears that, at least in the release candidate for NET2 this was a known bug; only binding to Data Sources | lets those dictionaries be populated. 2) I think it's weird that the "value" capability is tied to the parameters collection. That way it'd work with both types of data binding. I would like to confirm that this is a problem with the released version of NET2, so I can stop beating my head against the wall trying to get the Grid View to work "as advertised". As for the Grid View control doesn't correctly populate the Old Values or New Values parameters collection when performing udpdate operation, I think it is likely caused by some certain setting in the Grid View control... | | I would like to confirm that this is a problem with the released version of NET2, so I can stop beating my head against the wall | trying to get the Grid View to work "as advertised". - Mark Thanks for your followup Mark, Frankly speeking, I do agree with you that this is a big limitation since I haven't noticed this before until you mentioned this...

Follow bellow steps to know how to work with Grid View in ASP. Net Protected Sub Page_Load(sender As Object, e As Event Args) Handles Me. Bind Grid() End If End Sub Private Sub Bind Grid() Dim constr As String = Configuration Manager. Connection String Using con As New Sql Connection(constr) Using cmd As New Sql Command(“SELECT [Hobby Id], [Hobby], [Is Selected] FROM Hobbies”) Using sda As New Sql Data Adapter() cmd. Select Command = cmd Using dt As New Data Table() sda. Here simply the Edit Index of the Grid View is updated with the Row Index of the Grid View Row to be edited. C# protected void Page_Load(object sender, Event Args e) private void Bind Grid() VB. Data Bind() End Using End Using End Using End Using End Sub Grid View On Row Editing and On Row Cancel Edit events Edit When the Edit Button is clicked, the Grid View’s On Row Editing event handler is triggered. Note: You can only bind a Boolean or BIT Column to a Check Box Field. The Check Box Field values are fetched by accessing the Check Box Field column using its Index and then accessing its first Control which is a Check Box control. Namespaces You will need to import the following namespaces. The fetched values are used to update the record in the database table. A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.

To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.

How are you binding the data columns from datasource, through the Bound Field or template fields with customized html ? | | - Mark | Empty Data Text="the cart is empty" On Page Index Changing="grid Cart_Page Index Changing" On Row Canceling Edit="grid Cart_Row Canceling Edit" On Row Deleting="grid Cart_Row Deleting" On Row Editing="grid Cart_Row Editing" On Row Updating="grid Cart_Row Updating" Hi Mark, Thanks for your response and the code you provided, so you're using a custom class collection without using any Data Source control, I think this should be the cause of the parameters collection in Row Updating event being empty. Anyway, you can also add the suggestion on the MSDN feedback center.

Also, if convenient, would you post some detailed code snippet of your page and the code behind on this? All the parameters are actually associated to the Parameters declared in Data Source control (the select and update statement in Data Source control), also we can find some parameter name related attribute such as Old Values Parameter Format String="original_" So when we do not using Data Source control, there is no info for populating named parameters .... Also, I think it'll still require us to use Data Source Control when we need to Updating event to contains Parameters collection, however, it may become more user friendly if there're some additional functions on the Data Bound control which can help extract bound values from each row /column... ha AJ9Znc P8Ei3q L2 n GKN1K6B5U57An5w PDTl Bf TR hgoc D5IBPrxek8Ok Q6ARdran47 nw== | X-Complaints-To: ab***@| X-DMCA-Notifications: X-Abuse-and-DMCA-Info: Please be sure to forward a copy of ALL headers | X-Abuse-and-DMCA-Info: Otherwise we will be unable to process your complaint properly | X-Postfilter: 1.3.32 | Path: TK2MSFTNGXA02gbl!

As you can see in the image above our Grid View contains five columns.
