Asp net gridview rowupdating event
To do this, I created an instance of the Row Updating event for the Grid View. This event passes the necessary information to the method via the Grid View Update Event Args parameter. Find Control("Label20e"), Label) Sql DSupport Info.
If user clicks the Cancel button while Grid View is in editing mode, you need to Cancel the Editing process and also need to reset the Edit Index property to -1 in the Row Canceling Edit event of the Grid View control as shown below: The last step is to handle the Row Updating event to actually update the back end database.The visitors to a web site can typically be divided into two groups: the users and the administrators.In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.By Default, Grid View control displays Item Template which directly shows the Product Name and Unit Price columns but when user clicks Edit button Grid View automatically switches to Edit Item Template and display the control available inside Edit Item Template for user editing.Now I will show you the C# code behind file of the above ASP.To finish up then one has to set the Sql Data Source Update Parameters to the desired values.
The syntax for doing so is: Protected Sub GVSupport Info_Row Updating(sender As Object, e As System.
I found that simple data binding of my Drop Down List in my Grid View to my Sql Data Source was not going to be enough.
I would need to set values passed to the Sql Data Source control on the update event, and as part of this I would need to reference the controls contained in the row being updated.
These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.
I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.
NET page that will handle different Grid View events to provide complete editing functionality.
