I am using a gridview populated via a SQLDataSource. When editing or inserting data via the gridview, how do I trim the values before they are inserted to or updated in the database? I want to ensure that no spaces are accidentally added to the end of my text values.
View 4 RepliesI have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

View 2 RepliesI have a standard gridview, populated via a SQLDataSource, with columns converted to templates.
The edit templates have text boxes. When saving edited data via these text boxes, I need to trim the values to remove any spaces.
How do you recommend doing so? I've tried various methods but none seem to work.
Currently my update parameters are specified in the SQLDataSource.
I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I have a listbox inside a formview in a details page(master/details). The values for the listbox will come from a lookup table and when the user select one or more values it should be inserted in a table. The process sould be like the following:
The user will select one or multiple values and click on a Select button. Then a label should show the selected values. Then the user will click on the Insert button in the formview to insert it in the database.
i showed two column (Electronics,Photoshop) but i have six. i want to update their checked or unchecked condition in database (0,1) how do i do?
<asp:CheckBox ID="CheckBox1" runat="server" Text="Electronics" />
<asp:CheckBox ID="CheckBox2" runat="server" Text="Photoshop" />
<asp:CheckBox ID="CheckBox3" runat="server" Text="VideoEditing" />
<asp:CheckBox ID="CheckBox4" runat="server" Text="Gaming" />
<asp:CheckBox ID="CheckBox5" runat="server" Text="Coding" />
<asp:CheckBox ID="CheckBox6" runat="server" Text="Miscellaneous" />
Is there an easy way to trim values in a details view during edit mode? I tried modifying the database query to trim the values, but it didn't like to do both ways databinding after that. I tried looking through all the properties of the text boxes themselves and found nothing. I know I could add an event handler for the databound event, and set all of the values one by one, but this is an application that has existed since before my employment and there are over 40 values in this details view, all in text boxes with seemingly random names that have little to do with the values they represent or obvious naming scheme.
I thought maybe there was a way to way to iterate over the DetailsView.Fields property, but couldn't figure anything out there either. I am not allowed to change the schema from CHAR to VARCHAR either. Any other quick ideas? There is a strong likelihood this page will change again, and I would like something that might take care of this problem for any new fields added in the future without extra work. Unfortunately, redesigning it is not anywhere near a top priority right now, so a quick fix to alleviate some of the headache of using this monstrosity is all I am looking for.

I am using this command to trim a cell value from a grid view.
row.Cells[i].Text.Trim().Length
The result return is always 6.
I have checked that the value of this is empty, when I display it on page using this code,
Response.Write(" '" + row.Cells[i].Text.Trim()+ "'<BR>");
I get ' ', it seems like there is a space in it.
I'm inserting data into a SQL database through a detailsview. When a user inserts an incorrect data type or leaves a required field blank it shoots off to a big error screen. Is there a control that I can use that will allow it to give an error (with a little star or something) that says which field is incorrect without the big error screen?

View 1 RepliesI have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.
AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?

I have a web app I'm creating and a form that has a formview control on it. The form's default is set to insert and when the user enters data and clicks save, the data gets saved to the database; only problem is that the form then clears all the data out of the controls.
Upon saving after updating or inserting, I'd like to set the form mode to edit and also have it retain the values they input into the form. I've tried a few things and have not had any luck.
e.g.
Code:
Protected Sub frmCustomerInformation_ItemInserted(sender As Object, e As FormViewInsertedEventArgs)
' Make sure record inserted properly.
If e.Exception Is Nothing Then
If e.AffectedRows > 0 Then
litMessage.Text = "Customer Information saved."
'GETTING THE NEW quoteCustomerInformationId FROM THE SAVED RECORD AND PLACING IT INTO A SESSION VAR.
[Code] ....
What mode does the formview control have by default after it executes the ItemInserted method? Also, what is the prper way to do this?
Am not sure how to go about this... but i have two ddls on a formview which are not related but just insert and update into each other... Both are binded to the objectdata source....
Am issue just came up and i am looking for the simplest way on code behind that would automatically post a constant value (selecteditem) once the first ddl clicks on 1 or 2....
Example is
lst DDL Second ddl
ABC bko
DWC loct
qwe jjjj
Now when ABC is clicked... it should automatically bring out JJJ on the second ddl.... I just want something i can do on code behind.

I am *VERY* new to ASP.net. This may seem simple to you all, but I'm really lost. I have a small sized page with three text boxes (part of the InsertItemTemplate) of a formview, and a slightly modified link the system generated to submit the data to be inserted in the database:

If this page is run, it inserts the data into the database fine, clears the form and sits there. I want it to return a simple "Thank you" page in a window of the same size, with a Close Window buttom at the bottom to close the window:

When I set the postbackurl property on the first page, everything appears to work, except the write is never done to the database. If I remove the postback, it works as it did previously.
DetailsView has 2 properties: AutoGenerateEditButton, AutoGenerateInsertButton for hadling Update and Insert. Is there any way I can use asp:Button or some other buttons to hadle the same tasks?
