Forms Data Controls :: CertId Field In The GridView Has Visible Set To False?
Aug 10, 2010<asp:ButtonField Text="Void" ButtonType="Link" CommandName="Void" />
' RowCommand
Dim f_iIndex As Integer = Convert.ToInt32(e.CommandArgument)
Dim f_oSelectedRow As GridViewRow = grdMeterCorrection.Rows(f_iIndex)
Dim f_oCertIdCell As TableCell = f_oSelectedRow.Cells(11)
Dim f_sCertId As String = f_oCertIdCell.Text.Trim
If e.CommandName.ToLower = "void" Then
Dim f_bVoidRet As Boolean = VoidCert(f_sCertId)
End If
The problem is the CertId field in the GridView has visible set to false. I think this makes the value unaccessable to the RowCommand.
Forms Data Controls :: Looping Through Gridview Calling Visible False Cells?
Jan 10, 2010I have a gridview that serves as a confirmation for user input in a previous form from a previous page. The grid is databound to a temporary table where I store the user's initial selections. The user can confirm what they had submitted, (which may be more than one row of information, up to three classes) or go back and change. When they hit the confirm button, I loop through the gridview and enter a row in a permanent database for each row in the gridview. This works great.
However, I don't want the gridview to display all of the columns that are actually in the temp database, because I'm carrying over 'usersubmitted, datesubmitted', etc, from the previous page for each class selected and this is redundant. (I do need to use all of the columns when they submit, however, to make a new row with complete information for each selected class in the permanent database) So, when I set the usersubmitted column visible false, for example, in the gridview, the dataset table adapter insert function fails with a data type mismatch error. I'm assuming becuase the column has to be visible, becuase when I make it visible again it works.
Can you loop through a gridview and call on cells in columns that are not visible?
The first page is like this:
the user fills out his info once in text boxes
name ____
address____
then selects up to three classes in dropdowns:
class one dropdown ...
class two dropdown....
for each dropdown, I insert name, address, class selected into a temp db Second page.
Gridview should display only classes selected, one row for each, and not
name address class selected
name address class selected
then when they submit, I insert
name address class selected
name address class selected
one row for each in permanant database

Forms Data Controls :: Gridview Update - Bound Fields Visible Set To False Not Working?
May 20, 2010I have an Objectdatasource configured with Select, Insert, Update & Delete queries in a Dataset. This datasource is linked to my Gridview. I do not require all fields in the table to be displayed or updated in my grid so i have turned off the Visible property on several.
However, when i go into Edit mode and trigger the UPDATE to the database table, i get NULL values updated in the columns i set False for the Visible property.
How can i remove these columns from the GridView and the Edit mode and still have them UPDATE with their current values instead of being overwritten with NULL's?

Forms Data Controls :: Cannot Access GridView.HeaderRow
Sep 17, 2010I've searched for this problem on Google and also on this forum (and also this forum using Google) so if there is another topic dealing with this I apologize but I couldn't find it! :)
My problem is that when I try to access the HeaderRow property ASP freaks out and gives me the infamous 'Object variable or With block variable not set.'
error. Here is the code in question:
Public Sub gvwResults_DataBound(sender As Object, e As EventArgs) Handles gvwResults.DataBound
gvwResults.HeaderRow.Cells(7).Visible = False
For Each gvr As GridViewRow In sender.Rows
gvr.Cells(7).Visible = False
Next
End Sub
The line 'gvwResults.HeaderRow.Cells(7).Visible = False' is what raises the error. When I remove it, the code works just like expected except that the header row of the 8th column isn't invisible like I'd like it to be.
I'm pulling my hair out here, this is the very last thing that needs to be finished before this app is usable haha. :)

I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?

Forms Data Controls :: Need Gridviews Visible Property False?

Forms Data Controls :: Changing Fields Visible Property To False In DetailsView?
Apr 15, 2010I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.

View 2 RepliesForms Data Controls :: Displaying Data In A Grid View Control When Set A Row To Visible = False
Aug 23, 2010I have a problem displaying data in a Grid View control when set a row to visible = false when a certain condition is true.
For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.
The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.
How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.
