I have a gridview. In my RowDataBound handler I'm doing some things to columns, and accessing them like this for example,
e.Row.Cells(7).BackColor = System.Drawing.Color.Salmon So, of course when I rearrange the order of my columns everything breaks.
Isn't there some way to give an ID to a column, and say e.Row.Cells("TotalColumn_ID") ?
Will this work? Do columns have IDs?
I want to show columns in gridview based on access rights/roles.That is i want to show parents column if there is parents login or else i want to show students column if there is students login.

View 1 RepliesI've created a gridview having an Id column whose visible property is set to false, because I don't want users to see that column. Now when user clicks on the edit button in a particular row I want to fetch the id of the cell in the Id column of that particular row. So, for that purpose I used -
void GridView_RowEditing(object sender, GridViewEditEventArgs e)
{
string Id = GridView.Rows[e.NewEditIndex].Cells[0].Text;
}
In the above code, Cells 0th index is the column index whose visible property is kept false. Now the problem I face here is that if the columns visible property is true then I can easily fetch the contents of that particular cell with the above code. But, in invisible mode I get only "" value i.e. I don't get the text or the content of that cell. Why does it happen? I don't face this problem with DataGrid Control used with 1.0 and 1.1 version. And how to resolve it or in this case is there another way of fetching the content of the invisible cell?
I have search for a long long time and could not find a solution to access to grid view's column properties. I have binded a grid view through this method, the bindGridView function will return a table with columns and rows.
The problem here is I cound not access to columns properties such as Grid_View.Columns.Count or Grid_View.Columns[0]."something". It seems like the grid_view does not have any column. But I can access to the Rows properties.
I have put this code within a (!IsPostBack) and set the AutoGenerateColumns to true?
I need to access to columns badly as I need t add additional column to the binded grid view.

I'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and

EMP2 1 2 3 4
I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>
The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.
I get the error "
Must declare the scalar variable "@PLAYERID"."
Currently I have something like this, but when I click "update" the record doesn't get updated (but no error is returned).

I am using Visual Studio 2010 where I have a gridview that displays many columns and because of that the user has to scroll horizontally in order to view the rest of the columns. Is there a way to split the columns so that each row will contain some columns and some columns underneath them? For example, I have 10 columns where each row will show 5 columns with their headers and the other 5 columns below with their headers.
View 2 RepliesI need to create a grid where the users can see all the memberships, and have a line of checkboxes for each existing role, and be able to check/uncheck roles to allow access authority.
I managed to build a datatable that adds columns and displays them properly, but I have not been able to programatically add columns to the grid based on whatever roles are stored in the system.
I can display the users and their roles by just specifying AutoGenerateColumns="true" when I do that, the checkboxes are grayed out, and the users do not want to have to click a button to open them up.
Here is what I can't figure out.
How do I programatically add columns to the GridView? I have some code in Pageload, but it doesn't work, so it is commented out?How do I turn on all the rows for the entire GridView to edit mode? How do I access the column name for the role they just checked so that I know what to add with the ystem.Web.Security.Roles.AddUserToRole(UserName, Role)?

View 5 RepliesI have a gridView that returns 12 columns / Fields. I want to only allow 6 columns per row and on the 7th have the 7th column move below the first 6. Example: ...
View 2 RepliesI have a gridView that I want to only show 5 columns per "Row". To explain, lets say I have a gridView that has a total of 20 columns. Normally this would mean that the grid would show all 20 columns in a single row side by side:col1 col2 col3 col4 col5 col6 col7 col8 col9 col10 ... etcI want it to instead show the columns underneath each other like so:
col1 col2 col3 col4 col5
col6 col7 col8 col9 col10
col11 col12 col13 col14 col15
col16 col17 col18 col19 col20
of course the prespective data associated with the columns would show below each column header.I have read some posts and they are pointing me to a repeator but I am not sure how I would impliment a method like that. Any suggestions / examples of ways you have done so or read about?

I have gridview which auto generate column is false, and I add some template columns, databind with a class ClassA . it works fine. now, I need add some columns to this gridview. the problem is: I do not know the # of columns that will be added (it is dynamic), and the data with these columns is in ClassA, but it is a array (or list). so, there is no public property for these data, only the array.
now, what I did is: I dynamically add template column to the gridview (column header ...), so, it shows the correct columns in the gridview, but how can I bind the data? I found some example, i.e.
[URL]
but it is for aleady know the data field (which is a public property in the class). all I have is just a array, and I need bind them to the newly created columns in sequence.
i am having a gridview in which all columns get dynamically added, i applied sorting in it, all column added as boundcolumn get sort properly but two column which are added as templated column do'nt get sort. Though my dataview have these column as it is.
