Forms Data Controls :: Stop FormView Inserting SQL Data Again On Page Refresh?
Jun 15, 2010I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?
Forms Data Controls :: Inserting / Updating Sql Data From A Listbox In Formview?
Jun 2, 2010I have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.
In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.
<td
style="width: 454px">
<asp:ListBox
ID="lbox_ConstructionType"

Data Controls :: How To Avoid Exporting Certain Column Headers In GridView
Oct 9, 2012I have boundfiled column inside gridview and made the column as invisible by setting visible="false".
But while exporting the gridview to excel I am getting the Header text alone exported. Wherever the column's visibility is set to false the header text should not be exported. After binding the gridview I have set the column's visiblity to false so it won't export the column values.
The problem is to stop exporting the header text to excel. Let's say column index is 10
