Forms Data Controls :: Gridview Taken Back To Most Recent Session After Updating ?
May 20, 2010
I have a dropdown list with sessions: Summer, fall, spring, summer Interim.
And also have a gridview to display hours of those sessions. When chose session from dropdown it displays the data related to gridview.
Gridview has the 'Edit' option to edit hours for each sessions:
[Code]....
When I edit let say spring and update the field it redirects me to main page but everytime it selects the data from summer).
What I want is? If choose Fall from dropdown and make edit(in editpage.aspx?id=..) and update the data, then it should redirect to main page but choose the Fall from the dropdown (Not summer)

I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?

I have a listview showing the data, and that i will use to Show, Edit, Delete, and Insert data.
I added a ASP.NET Ajax HTML Editor to the EditItem Template.
I click on EDIT button and it turns into the EditItem Template, i modify the data and when i click UPDATE it does nothing.
Neither updating data or turning back to ItemTemplate.
Here is its code:

I have a table which have different records in it, When user click on each record I save the primary key of the record to another table (recent viewed) with short date and time. It checks first if that record is already there so it just update the data and time but if record is not yet there then it will add it.
I want that the recent viewed table only store 15 records in it. Not more then 15 and most oldest added record should be overwrite. Is that possible in MS SQL server 2008?

I have been researching this for quite a while. I'm a beginner ASP.NET programmer using Visual Web Developer.
I create a database and then allow users to add data to it. I also display the data on a repeater. At the moment the data is being displayed from the oldest data to the newest data. I want to displau the data from new to old. I want to sort and display the data according to the items' IDs.
e.g.
LATEST MEMBERS
ID:10
Name: Donnie Dollie
ID:9
Name: Liam Stan
ID:8
Name: Frank Fro
Older members>>

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 want to make sure I go about this in an efficient manner. I have a gridview. On the gridview, I have some columns that are read only values . These values go through calculations based on values in a database. The stored procedure takes information in the database, does some simply calculations (this value * that value / another value type of stuff) then returns a recordset as a datasource for the grid.
Other columns on the gridview have values the users can enter data. I want to be able to provide a recalculate button that will run calculations based on the entered values which will change the readonly values and then repopulate the gridview's read only values without going back to the database. This recalculate button is not the save to the database button. The save to the database button will take the values in the user entered columns and save them to the database. Then, the next time the grid is called, the page calls to the database and loads the grid.
So, what I'm looking to do is allows for recalculations on a gridview, a gridview with about 24 columns and about 1000 rows. My first thought is to create a class that reads the gridview and then applies the business rules, then updates the gridview some how. Or, maybe have a dataset table thats i read the value from the user inputs, then apply business rules and then bind the gridview to the dataset table. Do any of you have thoughts here, maybe have done something like this?

I have a gridview and I want to update a cell with a session variable username. In the Gridview1_RowEditing event I have this code :
GridView1.Rows(e.NewEditIndex).Cells(5).Text = Session("username")
It does not give me any errors and seems to work but the grid view cell do not take this session. When I'm clicking on the edit hyperlink this event is triggered.

Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement
UPDATE SimpData SET store_nbr = @store_nbr, date = @date, data_type = @data_type, acct_1 = @acct_1, amt_1 = @amt_1, acct_2 = @acct_2, amt_2 = @amt_2, acct_3 = @acct_3, amt_3 = @amt_3, cheque_nbr = @cheque_nbr, cheque_amt = @cheque_amt, gst_hst = @gst_hst, qst = @qst, comments = @comments, uploaded = @uploaded

I have a gridview that holds 4 columns. in the fourth column there is a DropDownlist that holds three items.
I want my users to select one of the values and when they do the auto post back (which is set to true) should execute a method that updates the database selected row. But do i use the selectedindexchanged of the DDL or the Gridview? My head is totally thrashed so i imagine its really simple and im just over thinking it.

I'm using a GridView to retrieve data from a stored procedure using a SQLDataSource (db is SQL Server 2008). When I compile my application and go to my website, all the data is loaded and shown fine. If I was to add a new entry to the table however (a seperate page on my website has a Wizard control to facilitate this) and then return to the page with the GridView, the new entry doesn't show up.
Looking from SQL Server, the data has been added, but the GridView isn't updating to show it. If I were to recompile the project with F6 and refresh the page, the new data will show up. I tried calling DataBind() on the GridView in the Page Load event, however the issue still remains.

where I have gone wrong? changing from VS2003 DataGrid to VS2010 GridView; still on SQL Server 2000 so the wizards for autogenerating the code are not compatible.
Delete works, RowUpdating does not. I get an ArgumentOutOfRangeException on "rowToUpdate("QuoteDQty")

I have a GridView in ASP.NET. I have an Edit CommandButton for every line in the GridView to edit the data on that line. All of this works fine except for the fact that when the user clicks on Update, it does not update with the correct value that the user entered. I have this as a Template field with the textbox to edit bound to the field, so it updates when the user changed the value and clicks Update. However it does not work. I have tried almost everything and its very frustrating. Here is the code for the Data Source:
<asp:SqlDataSource ID="Table1DataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>"
InsertCommand="INSERT INTO TABLE1(ProjectId, WBS, WBSTitle, VersionId) VALUES (@ProjectId, @WBS, @WBSTitle, @VersionId)"
DeleteCommand="DELETE FROM TABLE1

I have a gridview with the ObjectDataSource and the Update does not work. When I click on Edit, I go to Edit mode but Update will not work at all. No errors. I do believe that it is in the RowUpdating method but cannot figure out how to call the method UpdateBook from the BookManager BAL.
