ListView Not Inserting Records

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :ASP.Net

Hi all,

Here's the next instalment of my asp.net data access nightmare!

I've got a listview on my page, and when I run the page it correctly displays the data that it should.  However, when I add data into the empty new record and hit the 'Insert' button the page posts back but the record isn't inserted.  Annoyingly, I don't get any error!

The listview's datasource has an INSERT command and insert parameters specified.  The button seems to be triggering the listview's insert method because the ItemInserting event fires.

With no error message to go on I'm struggling to figure out what the problem is.  I have a feeling it's something to do with the makeup of the page.  The listview in question is nested within an Accordion control and the listview's data source isn't set until runtime, when it's done in the ItemDataBound event of the Accordion control.  As I say, though, it does RETRIEVE data correctly, it's just the inserting that's a problem.

I created a new, blank page with just this listview on it using the same code but not nesting it within any other control and hardcoding the datasource instead of setting it at runtime and that works perfectly, so I'm confident that my INSERT command, insert parameters and so forth are correct.

I've tried

Listview: Inserting is not supported by data source 'SqlDataSource2' unless InsertCommand is speci



Does anyone know why I would get this error when adding '<%# %>' around my sqlDataSource's InsertCommand?

The SelectCommand works just fine with the '<%# %>'.

When I remove the above from the InsertCommand, it works fine, but I need it to fetch a value from parent Listview.

                    InsertCommand='<%# "INSERT INTO [Project_Detail] ([Project_Master_Key]) VALUES (2)" %>'>

 <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:VmedIntranetConnectionString %>"
                    SelectCommand='<%# "SELECT * FROM [Project_Detail] Where Project_Master_Key = " + Eval("Project_Master_Key").ToString() %>'
                    InsertCommand='<%# "INSERT INTO [Project_Detail] ([Project_Master_Key]) VALUES (2)" %>'>

Here is my full code, maybe it makes more sense. It is two nested ListViews, the second one has the InsertCommand. It receives the parent Key, and suppose to create

Insert on button event is inserting 2 records at a time


I have a form that is doing a simple insert, then a sub insert of a certain drop down selection is made. What i dont get is why the main insert is inserting duplicates and the sub works fine inserting 1 record per text as expected. I click the button 1 time, and when i check the table, there are 2 new records.. As you can see the insert is not wrapped with any conditions, once that is inserted i check if a slection was made and runs the sub insert.

My full code can be found in this post(http://forums.asp.net/t/1608619.aspx), but here is what i have for my button event.

    protected void btnSaveServConfig_Click(object sender, EventArgs e)   
        dac.insertServerConfigintosql(txtEmailLogin, txtEmailPass, Convert.ToInt32(ddlNumEmail.SelectedValue));   
            if (Convert.ToInt32(ddlNumEmail.SelectedValue) > 0)   
                 Dictionary<string, string> camValues = new Dictionary<string, string>();   
                    foreach (HtmlTableRow row in table1.Rows)   
                        foreach (HtmlTableCell cell in row.Cells)

why is SPROC inserting two records instead of one?


Why am I getting two records inserted into the table, when I'm expecting and needing one?  The VB code below is checking whether the HTTP is secure or not, and if it is then execute the SPROC.  But for whatever reason, I'm getting two records inserted about 5 seconds apart.  Does anyone know why and how to fix?  I just need one record.  thanks

Error inserting new records


Hi i am trying to insert new records by using a stored procedure with the following code:

Inserting records into entity framework


I must be overlooking something simple here.  I have a listview control with an entitydatasource as it's data source.  The Listview is used to insert, delete, edit and view the records.  So far so good.

I want to be able to filter the records that are returned, and I'd like to do this in the code behind.  So instead of setting the listview.datasourceID to the entitydatasource in the .aspx page, I want to bypass the entitydatasource altogether and set the listview.datasource in the code behind.  But now I have a problem inserting and editing, and I'm assuming deleting.  Appartently I now have to write the code in the ListView1_ItemInserting, ListView1_ItemUpdating and I'm assuming the ListView1_ItemDeleting events.  Is this expected behavior? 

Here's what I'm doing in the code behind:

Dim context As New WAPEntities
Dim tags = From t In context.MetaTags
                Where t.page.StartsWith(prefix)
                Order By t.page
                Select t
ListView1.DataSource = tags


Inserting new row in GridView in ASP.NET 2.0

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

ASP.NET GridView - edit records using JQuery Dialog

There are many ways in which you could modify modular data in Grid View:

2. By using separate pages for Edit
3. By using popups/dialogs for adding/editing

WPF Tutorial - Using The ListView, Part 1

Many of the controls in WPF have a downright dizzying array of capabilities and features, due in large part to the composibility of all the components. The ListView control is a great example of this - the possibilities are almost endless. This series of tutorials on the ListView will hopefully make the space of possible options seem not quite as daunting

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance
