VS 2010 - GridView DataSource Edit
Jul 31, 2011
I have a DataView that is bound to a DataSource, which gets its data from a SQL database.I'm converting a desktop app to a web app and I've been able to duplicate the data query side, but I'm having a hard time inserting a new record via the data source. In the desktop app, I don't use a data source. I have a class I created that inserts a new record, but the upkeep is extremely time consuming, so I'm switching to the datasource.When I assign the datasource, I selected the SQL statement/stored procedure option and created my INSERT command via the Query Builder.
The problem I'm running into is that I don't want a SELECT statement. I just want a plain GridView so I can select Edit, fill in the data and then call InsertParameters.If I don't add a SELECT statement, it won't let me finish the wizard and an invalid one throws an exception. The only other thing I could think of, was to call SELECT and set a WHERE based on a column whose value is null. The app runs, but the GridView doesn't appear. How I can only do an INSERT?

I have a gridView that is populated with a dataset from an Oracle Database.
When I click on the EDIT button, it will redisplay my gridView with textboxes so I may make some changes.
Let's say one row is currently:
OPEN_TIME = 1 CLOSE_TIME = 2
When I click EDIT, 1 and 2 are in a textbox. If I change both values to 5 and click UPDATE, it will fire a RowUpdating..
Here is the code from my APP:
Private Sub gvBusinessHours_RowUpdating(sender As Object, e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvBusinessHours.RowUpdating
Dim strOpenTime As String = DirectCast(gvBusinessHours.Rows(e.RowIndex).FindControl("txtOpenTime"), TextBox).Text
Dim strCloseTime As String = DirectCast(gvBusinessHours.Rows(e.RowIndex).FindControl("txtCloseTime"), TextBox).Text
End Sub
The problem is the values I am getting are the OLD ones and not the new ones... I am getting 1 and 2 and not 5 AND 5...
what I am doing wrong ?

In my gridview, when in non-edit mode, my edit (pencil) and delete (X) buttons show up side-by-side as expected:
Attachment 130089
However, when I click the edit button (pencil) to go into edit mode, the update (diskette) and cancel (undo arrow) appear as shown below, and the edit and delete buttons of the other rows appear the same "wrong" way as well.
Attachment 130091
Here is the code for the grid:
Code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" GridLines="None">
<AlternatingRowStyle BackColor="#F7F4ED" />
<Columns>
<asp:BoundField DataField="Fname" HeaderText="First Name" />
<asp:BoundField DataField="Lname" HeaderText="Last Name" />

I have a gridview that pulls data from two tables, CLIENT and PAYMENT. I want to add the edit, delete functions to the gridview for the payment portion of the table, that is to edit or delete the payments but not the client. I've manually enabled the edit, delete functions and input the queries. I've also deleted the textboxes from the templates which draw from the CLIENT table so they cannot be edited. Everything looks good on the surface until I actually go to edit or delete anything, and it has no effect.Here's the structure of the two tables:
CLIENT PAYMENT
ClientID Pk PaymentNumber Pk
FName CLIENT$ClientID Fk
LName PaymentDate
ContactNo NULL PaymentAmount
ArrivalDate PaymentDetails NULL
DepartureDate NULL
CurrentResident
Here's the update query:
UPDATE [PAYMENT] SET [PaymentDate] = @PaymentDate, [PaymentAmount] = @PaymentAmount, [PaymentDetails] = @PaymentDetails WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate
AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails) OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))
Finally, here's the delete query:
DELETE FROM [PAYMENT] WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails)
OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))

I have a Gridview that displays some data I am pulling from a SQL Server database. The stored procedure that runs the query accepts a table valued parameter. I am unable to find a way to pass this structure to an asp:SQLDatasource so I have been manually creating the datatable and then binding my Gridview to it. The DataType I am using in the code-behind to pass into the stored procedure is a System.Data.SqlDbType.Structured type.
Each Gridview row has an asp:LinkButton with a CommandArgument value that looks like
<%# Eval("PartNumber").ToString() + "|" + Eval("ID").ToString() %>
Each LinkButton calls back to a function in my code behind that accepts the CommandArgs, does some work, and redirects the user to another page.
Since I am manually binding the Gridview to the Datasource when the number of records exceeds my paging size and the user changes pages or sorts the Gridview, the CommandArgument value changes to the wrong row and I get bad data back from the CommandArgument. how to pass a System.Data.SqlDbType.Structured type into an asp:SQLDataSource but if that is not possible how I can work around this?

I have a user requirement to hav the ability to directly edit the gridview without having to click the edit link. I was thinking of showing dropdown lists for each column-to-row so that the user can select the values for each record. Then the table will be updated accordingly (no update link).
Is this possible or do I still need the edit template and specify the item template with the dropdown list?

I have a grid view with edit and save buttons when I click on edit it is letting me edit it and if I click on save it is lettingme save the data that I have edited.
The thing is after save is done it is showing the data in edit mode i.e <edit item template > mode I am still seeing the textboxes if I refresh the page then I am seeing it normally.
How can I stop the gridview to show edit mode after the save is done?

Can someone tell me if there is a technique to make an entire Column within an gridview (for example digits) editable (instaed of a single row) and update this column after changing values by press an Update-button?
A commercial solution is also o.k. with me, but, of course, a method to do it ourselve would be nice.

I have a page with 2 GridViews on it. The top GridView shows all the Bike Riders the bottom GridView shows all the Bike Lockers. I have set up both GridViews to be able to Edit the data. And the top GridView to Select.
When I click the Select buton on the top GridView I programically reset the DataSource for the bottom GridView to show the Locker for the Biker of the top GridView Selected.
So far everything works great. I select a Biker on the Top GridView and the Bottom GridView resets just showing one record for the bike locker.
The problem is that if I then click on the Edit button on the bottom GridView (The Bike Locker GridView) the GridView goes into the Edit Mode but it now shows all the Bike Locker records and the edit record is always the top record of the GrdView.
Here is my code Behind:

Although Enable Edit and Continue is checked on the Web tab of my ASP.Net MVC 2 project, I cannot in fact change the source code while running. For example, if I try to edit a controller while paused in the debugger, I cannot change the file (acts as if read only).
I found a related post Edit and continue in ASP.NET web projects, however
The answers seem to suggest I should be able to at least edit the code, then reload the page to see the result.I don't know what the distinction is between a Web Application and Web Site projects

I am in need of a very simple grid which the user should be able to edit very quickly. The grid will display a list of food items (name and price) that make up a menu.
My usual approach here is just a GridView bound to a collection of the food items with an Edit button to the left of every row. When the Edit button is clicked I navigate to an Edit page where the user can edit that item and click OK to save it to the database and then go back to the grid page, where the grid is reloaded and shows the edited item.
This approach however is much to slow, the user should be able to edit the grid much more quickly, ideally without posting back (either fully, partially or via ajax).
What I'm thinking is really simple, but I don't have the necessary javascript skill to create this...:
A UserControl that simply creates a new row of TextBoxes for every food item (along with maybe a Delete button). The 'grid' is thus always in 'edit mode' (it always shows the textboxes in every row) and the user can type in any textbox to change the name or price. When this change is made, nothing happens server side, yet. When the user presses Save, I finally run a save method that just checks all rows and saves the new values to the database.
Since the grid is so simple (just Name and Price and the underlying data has a unique Id as well obviously) I think this should be possible, but I wouldn't know how to create this...
I did try, I had a UserControl 'MenuGrid' that was nothing but a PlaceHolder (and two labels for the 'Name' and 'Price' menu headers). It has a DataSource property that I set to a collection of food items in the menu, and then for each of those food items I add a MenuGridRow (another UserControl) to the Placeholder. This MenuGridRow contains two TextBoxes and the Delete button. It also contains a HiddenField control that gets the Id of the food item.
Loading works fine, I can get all the data in this 'grid', but I don't see any way to save it back. Once I changed the items and want to Save on the server, I don't see any way to access the MenuGridRows from the MenuGrid (let alone accessing the TextBoxes on that in turn). I think the problem is that it's all just rendered to html and during runtime there is no such thing as a MenuGrid or MenuGridRow anymore. So all I have is a couple of TextBoxes with seemingly random names and there's no way for me to determine which Textbox belongs to which HiddenField (which contains the Id).
Also, I don't see any way to handle the deleting of a row; I was thinking to just run some javascript that deletes the MenuGridRow from the MenuGrid, but again same problem, there's no such thing as a MenuGridRow at that point and I'd have to figure out which TextBoxes and HiddenField belong to that row and then delete them via javascript.
I tried looking for an editable ajax enabled grid as well, so I don't have to do it all by myself, but I didn't really find anything useful. Most of the grids I found don't even work properly, some work but are still very slow (there's still a postback, they just put the grid in an UpdatePanel but that doesn't make it any faster).

I got a IList<Category> where a Category have an id, name and parentid. Right now I loop over all categories where the parent id is 0 (so they are root) and for each of those child categories I call a recursive function that add the child categories to the child nodes. Works fine. However, I (think) I'm going to do away with the asp:treeview since now, next to each Category I want an Edit and Delete Link.

I'm trying to update items in my SQL database from a ListView. It works, but all entries in the database update. Not just the one I'm working on. I backed up the database prior to testing, so there's not any issues there.This is how my SqlDataSource UPDATE command is setup:
SQL Code:
UPDATE entries SET duration = @duration, checkinDate = @checkinDate, receivedBy = @receivedBy, cosmeticDmgIn = @cosmeticDmgIn, STATUS = N'closed'
I don't have any code setup to update the database, which is probably the issue.When I load the ListView, select edit, type in my edits, and click "Update", all the rows in my database, for that column, are updated with that data.I tried inserting the parameters manually, within the ItemUpdating event, but it never works.

357 Johny newFoo Hockey
358 mike Soccer
Public Function RemoveDuplicateRows(ByVal dTable As DataTable, ByVal colName As String) As DataTable

Dim duplicateList As New ArrayList()
For Each drow__1 As DataRow In dTable.Rows
If hTable.Contains(drow__1(colName)) Then
duplicateList.Add(drow__1)
Else

End If
Next
For Each dRow__2 As DataRow In duplicateList
