Forms Data Controls :: Gridview Delete Error With Linq And Bind Using Different Format?
Apr 12, 2010I have a gridview with linq and in the itemtemplate I have a column like this :
Bind("SUPERFICIE","{0:N00}")
If I display my gridview, I have this kind of value : 6'555
When I delete this row I have this error :
Failed to define one or more properties of type DS.MY_TABLE 6'555 is not a valid value for Decimal.
Apparently, when I use a format on bind, it change my values in my ds and I cannot delete my row!
I don't understand, because in my logic with the bind format I don't need to correct some formats for delete a row !
Forms Data Controls :: GridView Delete Command Fires Error When Using Template Fields Inside
Mar 6, 2011I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.

Forms Data Controls :: Dynamic Delete LinkButton In ListView Error "Delete Can Only Be Called On A Valid Data Item"
Feb 22, 2010I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:
1- footer

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?
Nov 18, 2010How 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?

To review: Each of the subject tables has a "RowID" field specified as Identity and as the Primary Key.The BoundField for the Rowid is set to ReadOnly. There is "Edit, Delete, Select" specified for the CommondField. Edit and Select operate as they should.
HOWEVER, Delete results in a "Must declare the scalar variable "@RowID" (with the associated "unhandled exception" verbiage).
