Forms Data Controls :: How To Delete An Auto Generated Column From A Gridview

Feb 1, 2011

I am currently working on a module in which I am creating an auto generated column gridview, and I have set the Auto generate edit button field to true. What happens now when I click the edit button The primary key field is turned in to edit mode which I want to restrict from being updated.

To restrict the same I have hard coded a template field which holds that column, But as I have set the AutoGenerateColumns Property to true the gridview automatically creates a duplicate field for holding the primary key column. For which I want to delete that particular column.

My Designer Code is:-

Forms Data Controls :: Best Way To Auto-format Auto-generated Grid Columns?

Mar 9, 2010

I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.

Forms Data Controls :: An Error Has Occurred Because A Control With Auto-generated Id?

Feb 25, 2011

Currently, I am programming a web-based application with Visual Studio.NET 2003, and having a problem with an err below :

An error has occurred because a control with auto-generated id 'dgPreventiveMaintenanceSchedule:_ctl5:_ctl3' could not be located to raise a postback event. To avoid this error, explicitly set the ID property of controls that raise postback events.

That err occurs while I am rendering my datagrid for certain data. In the other words, it occasionally happens.

I've been trying to debug one by one, but I still don't any clues for this kind of err.

Type Of Data In GridView / Listview Bound - Template And Auto Generated Fields

Aug 18, 2010

Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.

Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.

Data Controls :: GridView Last Row Delete Button Disable Functionality Not Working For Edit Button

May 7, 2015

In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.

I used below code for above:

 C#:

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();

[Code]....

problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:

Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"

Forms Data Controls :: GridView Edit Button Does Not Work At First Time

Nov 4, 2010

I have a simple GridView with AutoGenerateColumns,Edit and DeleteButton = true

It's data source is a DataTable dynamically generated.

Since i don't want to use object data source, i just catched Delete event and deleted rows from datatable and made a new databind. It works.

I tried to use also AutoGenerateEdit button, but when i click on Edit command field, nothing happes. So i decided to handle by myself edit events, and changed datagrid in this way:

<asp:GridView runat="server" ID="dettaglioprodotti" BackColor="White" BorderColor="#DEDFDE"
