ASP:Gridview bulk edit/update fields
I have a gridview on my web page that has two columns that are editable. These two fields are editable for all rows at the same time. How would I update all the fields that have been changed on the webpage using one update statement when the user clicks an update button? Right now I have an ontextchanged event on each textbox on the gridview. When the text is changed, I have a sub that should run called TextBox_TextChanged. Right now the TextBox_TextChanged event never fires when I change the field.

Well, you could set your update command in the same datasource the feeds the gridview. Then place a save all button somewhere on the page that calls an update function in the code behind.
Hope this helps,

'Update function
Sub update()
dim ind as integer
dim row as GridViewRow
for each row in dgRateDetailUpdate.Rows
ind = row.RowIndex
dgRateDetailUpdate.updaterow(ind,false)
next
End Sub

- You need to update database with changes in multiple records which are actually shown in a GridView.
- Trying to have TextBox_TextChanged event to fire.
To answer your first question I'll get back to you later but just keep in mind that GridView does/can not hold changes on the client for multiple records but allows you to have an Edit-Update-Cancel button/column to acheive per-record server-side based events which allows you to write your logic to appropriately handle the changes in your GridView data. If you need, I'll point you to some resources to do it and/or provide you with sample code.For the second question, I am copying the following from one of my earlier posts:
Further, as per my knowledge there are events such As TextChanged which are not fired automatically (means they don't create postback from client), although when some other control having postback functionality such as a button will create a postback, the TextChanged property of the textbox will be executed.
Although not related to Textbox but Hyperlink but the same could be done for Textbox by using a hidden button, I have answered on relevent but not exact question to use such as trick. Please see here:
