have trouble to add delete column to gridview when using specific query.I have PK set up at the table, I need add specific query to display dataat gridview:
SELECT [PID], [GID], [TID], [SID], [NEWSID] FROM [TableOne] WHERE ([NAME] = ?)
After builder this query, I click advanced button. However, generate insert, update, and delete Statements is not enabled.
I have a gridview were one of the colunms has a checkbox for deleting that row. When the user open the page the delete button is set to enable = false. If the user checks one box the delete imagebutton is disable = false. That works, now I need to add Javascript to enable the Delete button if the user selects checkAll, how do I do that?
View 2 RepliesBelow is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)

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.

Now i want to remove the Select, Edit and Delete link buttons in the last columns for a particular row. It should remain as it is for other rows. Only linkbutton from a particular row(being determined from data key) is to be removed.
I have been reading this forum post: http://forums.asp.net/t/1320074.aspx.I have found that I have to have the column which contains the image path showing in the gridview, in order to reference it using e.values("columnhere"). Is there a way I can do this without the column showing? I have tried setting the visible property to'false' but it still doesn't like it.

I have tried to query a table with an xml column by using XQuery and I can't get the Select to work.
All my knowledge/understanding of the subject comes from this MSDN article:
[URL]
so I am probably overlooking something minor:
I tried this query Select col1, Phone.Query('element CellPhone {I am not sure about what goes here} I tried {data('Phone/cellPhone} from aTable Where Phone.Exist('/Phone/cellPhone/text()[contains.,"412-8977"]') = 1 This syntax is definitely not fun.
How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?
Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:

and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

VS 2008 ASP.NET 3.5 app connecting to an MS SQL 2005 backend. The app contains a strongly typed dataset with a number of TableAdapters. I'm trying to add a query to one of the TableAdapters that deletes from table A, then related entries from table B, then related entries in the master table - table C. The query looks like this:
[Code]....
When I try to run that query to test it out, an error dialog box pops up that says "Unable to parse query text" followed by a second error dialog box that says "Must declare scalar variable @ID". Will the TableAdapters not run sequential Delete statements like this or did I do something wrong?
**Side note: A cascading Delete foriegn key relationship would be ideal, and was configured on the development database, but the DBAs messed up when replicating the database on the production server and getting them to fix something like this can be a difficult process.
