Rowupdating gridview newvalues

The hash key is the key of corresponding column and the value is the new value to be set.If the values are alternated in the dictionary they are applied to the grid. The hashtable consists of the new values to be set on the row cells.The above piece of code will also do the same as label in Item Template and Textbox in the Edit Item Template.By default all the boundfields will be trasferred as Textboxes in Edit Mode. We will use Template Field, whenever we want to define some custom control in the data bound controls like Grid View, Data Grid or Data Repeater.If he clicks edit (or) in the edit mode he can be able to see the Textbox.So am calling the method Bind Grid Data method which is overloaded . The hashtable contains former values of the row's cells.

I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. In the Row Editing function, the edit textboxes appear and I can get the "old" values Then the page renders, I edit the textboxes and hit Update.If we use proper command names for the buttons like “EDIT”, “DELETE”, “UPDATE”, “CANCEL” these will also trigger the appropriate Grid View Events.Ok let’s move on to Code behind what we have to do when user clicks Edit, Delete, Update and Cancel When we click on Edit the On Row Editing event will be fired.To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.
