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 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.
i use the grid view so edit & Delete the records. using
<asp:CommandField ShowEditButton="True" />
<asp:CommandField ShowDeleteButton="True" />
But due to more fields the gridview is out of the Master page.
So how can I manage the gridview columns especially at time of edit the records.

View 1 RepliesI didnt use bound field here.as it is simple grid view with auto generate columns. I want to make some columns Editable while some should not be editable

I have a table which has like 450 fields, i want to add edit option to my GridView which allow user to edit the data for that row.i don't wanna write ItemTemplate field for 450 fields, is there a way to get it done automatic query using ListView or GridView whatever is good for it.
View 1 RepliesI dont want them to be able to select a listitem until they click edit .
here is a picture of what it looks like now.
I have my gridview and its code is as follows
<asp:GridView ID="noticeDetails" runat="server" EmptyDataText="Currently there are no notifications." BorderColor="White"
BorderWidth="1px" AutoGenerateColumns="false" PageSize="10" Width="100%" CellPadding="10">
<Columns>
<asp:BoundField DataField="CampaignIDRange" HeaderText="CampaignIDRange"
SortExpression="CampaignIDRange" InsertVisible="False" ReadOnly="True" />
[Code] ....
I want to add a Edit button at the end of the grid view upon clicking on that button i can edit the grid columns.
Any method to resolve this query.
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 have a user requirement to hav the ability to directly edit the gridview without having to click the edit link. I was thinking of showing dropdown lists for each column-to-row so that the user can select the values for each record. Then the table will be updated accordingly (no update link).
Is this possible or do I still need the edit template and specify the item template with the dropdown list?
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

I have a repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:

However,I am not sure how to write the logic for hiding and showing the placeholder.I have written some code for the same but that clearly doesn't work.The following is the .aspx as well as the code behind which I am using:

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?

View 8 RepliesI have a grid view with edit and save buttons when I click on edit it is letting me edit it and if I click on save it is lettingme save the data that I have edited.
The thing is after save is done it is showing the data in edit mode i.e <edit item template > mode I am still seeing the textboxes if I refresh the page then I am seeing it normally.
How can I stop the gridview to show edit mode after the save is done?
Can someone tell me if there is a technique to make an entire Column within an gridview (for example digits) editable (instaed of a single row) and update this column after changing values by press an Update-button?
A commercial solution is also o.k. with me, but, of course, a method to do it ourselve would be nice.
- I want to put multiple rows of a gridview into edit mode
- I have not found any easy method to accomplish this task. I found a way to programmatically put a gridview into edit mode, but in testing the code below it works for only 1 row at a time :

I have a page with 2 GridViews on it. The top GridView shows all the Bike Riders the bottom GridView shows all the Bike Lockers. I have set up both GridViews to be able to Edit the data. And the top GridView to Select.
When I click the Select buton on the top GridView I programically reset the DataSource for the bottom GridView to show the Locker for the Biker of the top GridView Selected.
So far everything works great. I select a Biker on the Top GridView and the Bottom GridView resets just showing one record for the bike locker.
The problem is that if I then click on the Edit button on the bottom GridView (The Bike Locker GridView) the GridView goes into the Edit Mode but it now shows all the Bike Locker records and the edit record is always the top record of the GrdView.

I am having some trouble hiding a column in my GridView. For some reason when I do the following:

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 need my gridview to display no records when the user first lands on the page. Right now it's showing all records by default based on a query I've defined in a Table Adapter in my dataset.
I have 2 web controls that the user employs to filter data (or view all records). They are working fine--I just need to have the gridview show nothing by default.
