Asp.net - Add New Records To GridView But It Should Not Be Updated?
Oct 29, 2010
i'm having a gridview which is binded to a dataview, OnPageLoad i'm populating gridview records. and i have a textbox and a button, So now i want to add more Records to GridView but this records should not be get added into DB, they just added to the page and of course the default records which are coming from db stay.
<asp:GridView id="gvItems" runat="server">
<Columns>
<asp:TemplateField HeaderText="Item Code" SortExpression="ItemCode">[code]....
Basically at first Data From DB comes to page then after that Textbox data should get appended to the Gridview but Db should not get updated. i tried to do it by keeping DataView in ViewState or Session variable but later i came to know am going in a wrong way and that this won't work since Dataview can't be Serialized. i just need an idea or right path to do this, is this possible what am doing? [my alternative option ]: create a temp db table and save it... but i don't want to use this option..

I am using a table adapter and the update code as below in a Try/Catch block as shown on the MSDN site.
Me.MyTableAdapter.Update(Me.MyDataSet.MyTable)
This all works fine but I should like to return to the user a MsgBox which displays the count of new records added and/or existing records amended.I know I could count the records in the underlying table before and after the update, the difference being the count of new records. How can I count amended existing records ?

I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

I'm trying to write my first application which connects to an Access db. It took me hours to understand this, but I figured out that, if during the creation of the connection I chose to copy the mdb file in my project directory (VB asks this), I get that the database is not updated. Everything works, except the save button which saves new rows in the db. If I answer no, and the original mdb file is used, the database is correctly updated as expected. Is there a reason for this? Why is this happening? Shouldn't the database bu updated anyway?
