DataSource Controls :: Editing Data From A Gridview To A Database
Feb 7, 2011
As the subject says, i display a gridview filtered from 3 dropdownlist, wich all the items are from a local Data base, once i display this gridview i want to select a row with a button then and add, modify or delete data from it and then this new info is saved on the data base, so when i display the grid again i will see the new info. Im working on visual studio 2010, i dont use code behind, all is in asp .net.

I was reviewing my old post about this issue with a accessdatasource and that was simple since the Select, Update and Delete were all written within the datasource.
But this page im having issues with is using SQLDataSource and pointing to Store procedures. My issue is that i have created the sqldatasource with Insert(storeprocedure), Select(actual select statement), Update(storeprocedure) and was trying to take advantage of gridviews capabilities for editing when connected to a datasource that has all those elements setup.
Here is my datasource and gridview code: The gridview row goes into edit mode, but the changes never take affect on the database.

I would prefer that all middle tier methods that are used by GridViews be in the form that allows them to be used by ObjectDataSources...
<DataObjectMethod(DataObjectMethodType.Delete)> _
However, I am working on a project that I did not create. So, I was wondering if there is a way to use all the cool built-in editing functionality of a GridView without setting a DataSource? In other words, I am binding the datasource in the code behind (this works), and I have the following in my GridView...
<asp:CommandField ShowEditButton="True"></asp:CommandField>
And in the RowUpdating event (after the update button is clicked), I would like to call a stored proc to update a table and then use this kludge to get the GridView out of "edit" mode...
e.Cancel = True
grdWeeklyTime.EditIndex = -1
grdWeeklyTime.DataBind()
Is this possible or do I absolutely need to specify a DataSource in the GridView dropdown in design mode and then check the Enable Editing checkbox?

I have a MySQL database, and I'm currently creating an ASP.NET website to update data in it. I'm currently having trouble changing the data with GridView. Reading through various posts on this site, i think I've got a problem with binding the data, but I'm not sure how to accomplish this with MySQL database. My c# code is as follows:

My asp code is as follows:

At the moment I'm getting an error about the "trash" data, it's an Int32 field, but I'm not sure how to handle that.

I am looking for some examples for gridview for common tasks like displaying, editing, deleting, paging, sorting, batch updates etc, but WITHOUT using any datasource controls. I would like to bind the data in the code to custom object collection. all the samples I found on the web so far use some data source control, I think Enterprise applications shouldn't be using this pattern. objects in my solution have only business logic and no data access code. instead I use manager objects to do this. if you have any examples of gridview that performs the common tasks without using any data source control.

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database.

I have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.
Here is the page and the selectedIndexChanged sub for the piece of work I'm trying to accomplish...

I have a Gridview where the user can edit a row when he click on "Edit" (this is called update mode i thinck?).
When the editing is done, the user clicks on "Update" and the changes are written into the database. Additionally i set a "ChangeMarker" in the database that the data record has been changed by the user.
I identify the row in the database i want to update with the SelectedDataKey in the Gridview:

I ahve displayed a group of data in my gridvew with the edit option linkbutton template field for each row. The gridview columns consist of employee name and projectname and total hours field employee worked.
So in this when i click the edit button using the datakeynames alue for project name id and employee id ,i have to redirect the page to another page with the values in the grid for the particular employee.so that i can update the totalhours field in the redirected page.and if i press the update button in that page then the page should be redirected to the gridview page with the updated value for the particular employee and project. The page which should be redirected consist of project name dropdownlist, module field,date field and total hours field. No employee name field.
Using the gridview rowdatabound field i have postbacked the url page with the project name id but it does not displays the project in the redirected page.And employee name i have to redirect with the session value i think?
