Forms Data Controls :: Hiding First 2 Columns Of A Gridview But Keep Column Location The Same?
Oct 25, 2010
using vb.net/asp.net 2005
I have a gridview with columns (pseudo-code):
<COLUMNS>
AuthorFirstname
AuthorLastName
BookTitle
YearPublished
</COLUMNS>
what I would like to do is to only show the AuthorFirstName and AuthorLastName columns for the first row of each author. I am easily doing this with:
[Code]....
However the issue that I'm seeing now is the formatting what happens is that after the first row that the Author names are hidden but then the BookTitle and YearPublished become the new cell(0) and cell(1) respectively which means that book and year are displaying underneath the author names columns. so my goal is to do 2 things:
1 have BookTitle and YearPublished render under the correct headers and
2. For the second row and after I would like the cell to appear the same as the background, I dont want the user to be seeing what looks like an empty cell or textbox there.

My gridiview is mostly templated fields.
I have searched far and wide and discovered that if you hide gridview colums in the Gridview's databound event, as per the code below,then the objectdatasource binds multiple times according to the number of columns you are hiding. This is definitely the case.

I have a gridview control which gets data from database. One of the column is a checkbox and based on the value of the checkbox, I need to display 2 more columns. Currently I am having 2 issues:
1. I am able to achieve this when OnDataBound event gets triggered. Basically I am checking the row state and type and if it is in Normal mode I check the status of the checkbox and based on the status I am setting the style on the columns I want to hide (columns contain checkboxes). But for some reason, I am not able to hide the header. The GridView shows the header but the text boxes which are in the columns are hidden.
2. During Edit mode, I have attached a javascript to the checkbox and when the status of the checkbox changes, it hide/unhides the columns, again header cannot be made hidden. Also, if I use the Visible property of the header, I can make the header invisibly (only using the code behind) but when javascript is invoked on the checkbox during edit mode, it cannot find the controls as they are not visible and hence does not do anything. Since TemplateField does not support style property I can't even set the style["display"].

I am having some trouble hiding a column in my GridView. For some reason when I do the following:
[Code]....
It hides the column correctly but also leaves an empty gray column at the end of my grid which is about 5px. Ideally I don't want to remove the column but hide it, but if I do remove it is it possible to remove the binded that column represents?

I have a gridview that is being populated by an oracle DB. The gridview have 2 columns now one shows years and the other is a checkbox column. What is happening is my years column is very long and I wanted to know if I could split the column in half. I want say from 1970-1990 in the first column. The second column will have the checkboxes for the first. I want the third column to have 1991-present day and the fourth column to have the checkboxes for the third column. Can the grid view do this or is this something I have to do in oracle and have the gridview just display it?
ex.
1970 chk 1991 chk
1971 chk 1992 chk
1972 chk 1993 chk
1973 chk 1994 chk

I have a GridView with bound columns, for which I am manually setting the ItemWidth and HeaderWidth to 500px, and nothing happens. Is there some trick to getting this to work?
This is a column a large amount of text in it, and it keeps sizing to the width of the header text, which is simply "note". I don't want to set Wrap to false, becuase then the colummn could be thousands of px wide in cases.

i need to add a hyperlink to each gridview cell and when that cell is clicked pass the header text through the querystring to another page. I can access the cells value ok and pass that through but i cannot seem to access the cells column header text. when i response.write out a count of the gridview.columns it brings back 2 which is the template fields but not the dynamic fields i have tried this on the rowdatbound, rowcreated, page_load and page_unload. the count should be 12 its like it cannot find the dynamic columns at all. ?
here is my code for populating the gridview

I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

I've added this to the code behind:
'Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False 'End Sub
When I select another button from the radiobuttonlist I want this to fire (onselectchange). It works but only the first column is visible. So how do I add the above code to pageload?

I had a datagrid and I was hiding columns. This was working fine to show just the columns I wanted.
[Code]....
And then I realised I wasn't paging the data so I ticked that on then above code no longer worked. The Count was equalling 1 with the paging ticked on. Why would that be?
I also used the classic formatting and when I sort the columns the classic formatting goes funny, how can reapply the sorting to make it look classic?

Here's my radiobuttonlist:
<asp:RadioButtonList ID="Pending" runat="server" AutoPostBack="True" OnSelectedIndexChanged="Populategrid">
<asp:ListItem Value="250">Over 250</asp:ListItem>
<asp:ListItem Value="300">Over 300</asp:ListItem>
<asp:ListItem Value="350">Over 350</asp:ListItem>
<asp:ListItem Value="400">Over 400</asp:ListItem>
</asp:RadioButtonList>
I have a gridview set up to bring in all of the items listed in the radiobuttonlist. When the page loads the first time it comes in as showing Over 250 only:
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False End Sub
This is the code behind:
Protected Sub PopulateGrid(ByVal sender As Object, ByVal e As EventArgs)
'Select Case Pending.SelectedItem.Value ' Case "300"
Dim conn As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("PendingClaimsConnectionString").ConnectionString)
Dim cmd As New Data.SqlClient.SqlCommand
[code]...
I'm getting an error under the If pending.selected value = "300" and .Parameters.AddWithValue etc...saying operator AND is not defined for types Boolean
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False End Sub0

Right now when I bind data to my gridview, I have a column MemberNo that I use in the RowDataBound in another column for creating a link. Anyways, in the DataBound event i hide the MemberNo column. But I also have a routine where I need to loop through the rows and use the MemberNo. Can I unhide the column MemberNo to use for this routine and then hide it again? I assume I cannot use the data if it is hidden right?

have a GridView with two columns: Part Number | Part Details
When I search for the part number 12345, the gridview will display like this
PartNumber | PartDetails
12345 | image1 (image1 will see as document picture)
If I search Part Number and doesn't get any data results in gridview the information will be:
PartNumber | PartDetails
0 | image2 (image2 will see as red cross picture)
How to change the image2 in the same column cell 1 in the GridView when the data results are "0" ?
Here is my code:
<asp:GridView
Width="570px"

I need to make a link for all the rows in one column of a gridview(VB .Net) where the grid has been auto-created from the data source. The link would simply point to another ASP details web page. The examples I have found have all been in C# and I don't quite follow them.

I am trying to set come columns to invisible after all of the rows are binded but I'm having trouble. I'm hiding columns that have empty data which I save in a session variable. This works fine. Then I tried changing the columns visible property using the ColumnByName routine in the DataBound but that must be the wrong event because I do not think the columns exist yet.
The columns are autogenerated btw.
Where can I set the columns properties after it has binded? Can i do this before the columns are autogenerated the the screen itself?
