View 1 RepliesI have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

I would like to find a way to raise an exception if the Session is written to when in readonly mode. When EnableSessionState is set to "ReadOnly", values can still be put in Session, but the next request they will not be there. This seems somewhat dangerous.
One option is to create a helper class which we alway use to access session. However, this still leaves room for a developer to inadvertently use session directly, and fall into the "readonly" trap. Is there a way to create a CustomSessionStateDataStore that sits on top of the existing session code? I could not see an obvious way, and you can't inherit from System.Web.SessionState.SessionStateStoreData directly.
I have a .aspx page wherein on Button Click, I want to open a .txt file in ReadOnly Mode. Opened file will only be visible to user. User cannot edit the file and User cannot perform Save operation on it. StreamReader SR; string S = "abc", filename = "", physicalPath =""; string appPath = HttpContext.Current.Request.ApplicationPath; physicalPath = HttpContext.Current.Request.MapPath(appPath); filename = physicalPath + "\Files\temp.txt "; File.SetAttributes(filenam[Code]....
e, FileAttributes.ReadOnly); SR = File.OpenText(filename); The above code does sets the Readonly mode to the file but the file is not visible to the user on Button click.
there are 2 pages (SummaryGridviewPage.aspx and FormviewPage.aspx) there are insert, item and update templates in the FormviewPage 1st case - there is no problem to insert new record, select and update action in the FormviewPage
2nd case - However, there is problem when i select a record in GV and direct to FormviewPage for edit this code is added in Formviewpage to open the record at readonly mode, no problem
Private Sub RF_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Session("RecordID") <> "" Then ' to check New or Old record
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.ChangeMode(FormViewMode.ReadOnly)
End If
End Sub
however, no record if go further from readonly to edit mode then Code is added to the Edit button
Protected Sub BtnEdit_Click(ByVal sender As Object, ByVal e As EventArgs)
FormViewProject.ChangeMode(FormViewMode.Edit)
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.DataBind()
End Sub
Now edit problem is solved but when go back to the 1st case (new record, and then edit) Now new record can be inserted, and then show it in readonly mode. but then try to go to edit mode, no record show i think BtnEdit_Click code is conflicted with the built-in "Edit" command Could anyone show me some info how formview retrieve specific record in a proper way?
I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display?

View 5 RepliesI wanna join all the field as a new col.
but how can i ignore the empty field because i always join the field and separate by space like the following.
select (field_1+' '+field_2+' '+field_3) as new_col from TABLEA
but if the field is empty, then there is the double space
how can i ensure all the space is one space only.
I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
my gridview doesn't return to readonly mode after an update. i have set the editindex to -1did the databind() for the gridview too. but nothing works.setting keepineditmode to false doesn't work either.he documentation says that the gridview automatically returns to readonly after pressing the update button.my gridview is on a panel, and that panel is on an update panel.
View 6 RepliesI have a RadGrid which has a column like:
<telerik:GridTemplateColumn HeaderText="Car" >
<ItemTemplate>
<asp:Label ID="MakeLabel" runat="Server" Text='<%# Eval("Make") %> />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="MakeTextBox" runat="Server" Text='<%# Bind("Make") %> />
</EditItemTemplate>
</telerik:GridTemplateColumn >
and I'm wanting to set it up so that this column will allow input when inserting new values but won't when updating values.
I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection.
I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?
In my asp.net application, users are allowed to enter values into textboxes only from popup windows, so i have set the textboxes to readonly=true; this works fine for me until the first the record is saved. when the record is retireved from database and user updates these textboxes from popupwindows and tries to save the record, the record is never updated, i know the reason because textboxes with readonly cannot be changed on the clientside.
how to allow users to update the records for the textboxes with readonly property set to true.
I was wondering if when you add the update link for gridview records, is there a way to only allow the user to update just one field in the record?
View 1 RepliesI have a gridview which shows a list of data... at the end of each item I have added a button which is linked to the onclick event... when a button is clicked I want a value to update on that specific row... but I can't get it to work :( my code is below...
SqlDataSource 1 code...
UpdateCommand="UPDATE [PurchaseProduct] SET [BDConfirmSent] = 'Yes' Where [Id] = @Id">

I have a gridview that contains a textbox, a drop down, and a checkbox. The commandfield of the gridview has ShowEditButton="true". All of the gridview updating takes place in the "_OnRowUpdating" event. I have a Panel above the gridview with a table and some fields. Everything in the gridview works perfectly, the edit, the update etc., however, when I add a requiredfieldvalidator to the panel above the gridview, the gridview update functionality no longer works. e.g., clicking the update button does not appear to fire. If I comment out the requiredfieldvalidator, everything works fine.

View 2 RepliesI have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows

SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"

I get the error "
Must declare the scalar variable "@PLAYERID"."
