Web Forms :: GridView Updating Without Database Commitment
Mar 21, 2011
First off I'm using VS 2008 C# (3.5 Framework) and Linq2Sql for ORM. I have a gridview that represents a SQL database table. I want a users to be able to double-click the rows and get the edit items then be able to edit them and move on without them committing the changes to the database until the user clicks the save button. I know how to make the gridview work and all, my issue is that currently I'm having to keep session objects for the table data and edit them as opposed to a Linq2SQL datasource (because that seems to always automatically commit the change to the database). Also, I'm having trouble getting the changes in the edit controls to reflect in my session data objects. Does anyone have any great working examples of doing this type of work in a gridview. I know there are a lot, but I don't see any with Linq2SQL and not committing changes to the database immediately. Sorry I'm usually a back system developer, so I'm not a UI guru.

I have Gridview like that:
[Code]....
I bind data to GV in this way:
[Code]....
No problem with that. Now, I´d like to update the database with the dropdownlist in gridview, I wrote a method in this way:
[Code]....
The problem is when I click on the edit button there is nothing in the dropdownlist, it´s empty

I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.

I have an app where i have a GridView connected to a DropdownList....The selectedIndexChange determines what the gridview shows. Then have coded in the row editing event the ability to change the information in the row. MY ISSUE- cant take the new information changed in the row and update it in the database. I have a row updating event that im trying to figure out how to attach it to my stored proc and the newly edited row

I am sure I am not the first to ask this question but I cannot find an answer in these or any other forums. I guess I am not wording the question right. In short I have a gridview populated but a database via an SQLDatasource. I have an Edit column in the datagrid and an updatequery in the datasource. When the Edit is click the line goes into edit mode, the user then clicks Update and I get an error. Could not find control 'DropDownList1' in ControlParameter 'Frequency'. The only complication is that there is a drop down control when the "EDIT" column is selected. The dropdownlist gets it list from another SQLDatasource. This all works fine. Here is the code snip:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateEditButton="True"

I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.

I have a DataList that on Update calls a function "DataList1_UpdateCommand" to update the data
OnUpdateCommand="DataList1_UpdateCommand"
It does not actually update the new value typed in. I placed a debug on the line below, but the text in the "FieldBalance" displays the original value and not the updated value, but the web pages does display what I typed in and not the original.
Dim FieldBalance As TextBox = CType(e.Item.FindControl("txtBalance"), TextBox)
Below is the DataList code and the DataList1_UpdateCommand sub

I have a page where I want to let the users vote on displayed items. My customer wants this done with an image and a VOTE FOR THIS link. The link and image are to disappear once the user has voted, and be replaced with the number of votes for that item. I've made the VOTE FOR THIS link a link button. I'm have two problems:
1) the ListView1_ItemCommand code is always excecuted twice, so the vote count is being incremented by two, not one each time someone votes.
2) A page refresh causes the ListView1_ItemCommand code to run (twice) so a page refresh also casts two votes for the item
If it makes a difference, I display one item per page.

I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
How can i accomplish this?

I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>
The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.
I get the error "
Must declare the scalar variable "@PLAYERID"."

I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:
