Forms Data Controls :: Using Edit Command In Listview And Updating Database
Mar 4, 2010
i am updating data using editcommand by listview.. i got data max 50 depends on customers sometimes it has a few in the database. i am using listview and sqldatasource. when i update using editcommand in listview. it doesnt update relevant rows. it update to all data in database. why.. i have provided datasoure and list view.
I have created a simple application to edit data in an access database using gridview but its not working , the results are shown correctly , but when i click update nothing happens..
I am using asp.net(C#) as platform for building my application. I want to update the values in the database for the particular user & using the following code:
[Code]....
when I run this code, it works perfectly fine & there's no error, but when I check into the database, the values do not change & remains same. The default value in the database is NULL.
I have started practicing a little on asp.net c# and I have a very simple problem which i cannot figure out. I have th following datalist code and below the code I have attached a screenshot of how does it look like.
I have a gridview. Every time i click on the Edit command, it caused the Delete command fired. This gridview works fine on the test site, but it does not work on the live site.
I have a gridview and sqldatasource in a form. My sqldatasource has select,delete and update command. The delete command is working but the update doest not work when I click the update command field.
with a commandName="confirm" and its CommandArgument the memberid from objectdatasource. I have create a code behind to put certain action to the said button..
[Code]....
But it has no effect. Did I make some mistake? I'm still new in this ASP.Net things.
Within my ItemTemplate on a listview i have a link button carrying out a delete command. As it's a custom command i use the ItemCommand to do the deleting and have a stub itemdeleting.
It works fine set out like this however i only want the delete button to be available to logged in users. If i wrap the linkbutton in a loginview and then click on it the ItemCommand and ItemDeleting never get called the page just refreshes.
I have a detailsview control linked to a SQL DB. I have created a template field with various controls within. When I click on edit and change the values and press update. The detailsview control changes back to read only and displays the original values. I have attached the code for the control and datasource below.
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") = Me.dgQuoteList.Rows(e.NewValues.Item(1).ToString)" Private Sub dgQuoteList_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles dgQuoteList.RowUpdating [code]...
Data entered in textboxes is not getting updated in database. In debug mode I see that textbox1 and textbox2 in ItemUpdating event contain the same values as they had before calling ItemUpdating.
Here's my listview control:
[Code]....
What's wrong with updating of text1.Text, text2.Text in ItemUpdating event? Should I use e.NewValues property? If so, how to use it?
I would like to know if I can do the following: when I am in insert mode, can I dynamically change the select command of and then display that result in the second dropdownlist based on what was selected in the first dropdownlist.
I would like to include the minimum code to demonstrate what I am trying to do.
Is there a way to update a value in a gridview, by pressing a button that shows within the cell? For example, i have a really simple gridview showing supply levels, I havr the following SQL table:
ID = Int PartNumber = varchar Quantity = Int
I would like to be able to press a "Plus" or "Minus" button on the gridview next to the Quantity (in stock) value which updates the database and re binds the data to the gridview, but without going into edit mode.
I have a gridview and detailview in an updatepanel. My detailview is setup to display the details of a record that is selected in the gridview. When I edit the values in the detailview and click update it does not update the gridview. If I check my database the values have been changed it just haven't been updated in my gridview. Below is my code for the two objects and their datasources.
My GridView uses auto generate Edit & Delete command button. And then program the insert button. I want to do something when users click the Edit button so I wrote something like this:
[Code]....
When click the Insert button in the Footer, the program works fine. But when trying to click the auto generate Edit button, the following statement failed with the exception stated in the code above:
i have gridview i added it select command field i want when it is clicked,the id of the table displayed in label and i have update command field but the problem the update can't update the primary key i want when it is clicked update all the record
I'm using a formatting expression with a template field. When the details view goes into edit mode the formatting is applied. It looks great because it applies the currency formatting. It shows up as "$60,000.00" instead of "60,000.0000". But then when I do the update it gets rejected because of the $. Is there a way to keep the formatting for the user to see in edit mode but remove the $ when doing the update so I don't get the error?
The error: Exception Details: System.FormatException: Input string was not in a correct format.
I'm new to asp.net 3.5 and I have been working through the tutorials using a real access database to learn how to use the new controls. I have an extremely simplistic page setup with a master-details view, the master using the gridview, and the detail using the detailsview controls. Everything seemingly functions correctly, except when I try to update the data in the details view. I make changes to the record, click update and the page posts back but nothing is updated in the database. No errors are given either.
I have used this before with no issues. Now I get to the page with the detailsview using parms I pass with the key to the row. When the page opens the row I want to update is displayed.
I am having 2 issues. One when I change any of the fields and hit Update (the Edit button),
all rows are updating not just the row displayed. The second problem is I have an update_date and an Updated_by field with code in code behind in the Onitemupdating event and they are not updating at all. (This bit of code works fine in another page I have to updated similar fields on an insert).
I'm creating a confirm delete like popup with an iframe to use along with a gridview. When you click delete on a gridview row, the iframe shows up and asks if you would like to delete the associated image as well from the server. It works perfectly the first time I delete a row. After that whenever I click select or edit on a new row, it calls the rowdeleting event from the last deleted entry every time. I'm stumped.Here's the Sub:
'// Event that Occurs when the Delete Button is Clicked //' Protected Sub Confirm_Delete(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting Dim file_name As Array = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "/") If file_name.getLength(0) = 1 Then file_name = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "") End If Dim fn As String = file_name(file_name.getLength(0) -1) fn = replace(fn, ",", "%2C") fn = replace(fn, " ", "%20") Dim url As String = Me.Master.get_root_url & "CrimeBulletinProject/ConfirmDelete.asp?img_list=" & fn & "~!" confirm_delete_frame.Attributes.Add("src", url) confirm_delete_frame.Attributes.Add("style", "display: block; left: 50%") End Sub
I'm doing research on framework development for my company. SInce I will be developing a framework I can not simply declaire all my control in the code in front. Receiently I've been having trouble binding the controls from my ListView to my ObjectData Source. Basicly the properties in my DataObjectTypeName are not populated when the ObjectDataSource "Update" command is thrown. I recieve no error, I just get null values. All I need is an equivalent to this statement for code-behind ...
<%# Bind("AbstractText") %>This would solve all my issues. Ofcouse I will most likely need to bind the control's ID somewhere but that is not an issue. How do I Bind a control to a property in my DataObjectTypeName from the code-behind?
