I have two columns in my Gridview marked false for the visible property but which are clearly listed in the DataKeyNames that are still getting set to null in my database table on update.
The first one is a column MId# which is a type int. It starts as 0 but on edit is turned into null. The Second is RequireSKU which is also converted to null.
I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?
View 7 RepliesFrom what I understand within the Gridview Object you can have many datakeynames.
I have the field like this DataKeyNames = "id1, id2"
However, i don't know how to access the DataKeyNames individualy. For example. How do you access the first ID for the for a given row or the 2nd ID for a given row????

[Code]....
In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.
I have a gridView, with two DataKeyNames: MemberID, and CommitCustomerID.
One DataList has this sql statement:
SELECT * FROM [tblMemberProfile] WHERE MemberID = @MemberID
It pops up perfectly fine.
I also have another DataList with this statement:
SELECT * FROM [Incidents] WHERE CustomerID = @CommitCustomerID
I know this sql command works I have tested it with my data.
However I dont think the DataList is getting the proper value for the selected row in this DataLists case.
How can I make sure when I select the row in the GridView the proper parameters are going to the proper DataList sql statements?

Since I am using 2 DataKeyName is Gridview, so I have to pass both the DataKey while deleting Row from Gridview(using "Image Button" of Gridview).I tried it using below lines:
string name = GridView1.DataKeys[gvrow.RowIndex].Value["G_Name"].ToString();
string id = GridView1.DataKeys[gvrow.RowIndex].Value["Param_ID"].ToString();
I have a dataset.table which has some null values. am trying to trasform this using xslt to display like excel. If the value is null, then that node is ommitted by the xml. i tried deafulting the null values from the database itself and thats not generic. Handling null values is troublesome. I tried couple of methods to default null values by looping and thats not optimal solution. I used LINQ to handle null values but couldnt comeup with a neat solution. what am looking for is a generic optimal solution to handle these values.

When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the
first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.
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 trying to sort Columns in Gridview. In case, I set AutoGenerateColumns="true" and code the gridview as under:
<asp:GridView ID="GridView1" runat="server" AllowSorting=true onsorting="GridView1_Sorting">

And in .cs:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
ViewState["sortOrder"] = "";
[Code]....
ie if I set AutoGenerateColumns=false and define Template Field, Sorting is not done. Can Anyone tell me how to sort a Gridview when AutoGenerateColumns is set to false and Template Field is defined?
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)?
