I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?Â
I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
I have a grid view which is dynamically generated via C# using a DataSet. I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column.I have tried the following but it doesn't seem to work? hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage. c#
DataColumn ColImplantCustomerDetailsID = new DataColumn();
ColImplantCustomerDetailsID.ColumnName = "Implant ID";
ColImplantCustomerDetailsID.DataType = typeof(int);
ColImplantCustomerDetailsID.Visable = false; <-- visable doens't work here.

How do I pass a GridView column value to the code behind with out making it visible? In the following code, I would like to capture the ContactID with out making it visible in the GridView.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"
OnRowCommand="_OnRowCommand"
>
<Columns>
<asp:BoundField DataField="ContactID" HeaderText="ContactID"
SortExpression="ContactID" InsertVisible="False" ReadOnly="True" />
.....other columns in the grid....
<asp:ButtonField ButtonType=Button CommandName="Remove" Text="Remove" />
</Columns>
</asp:GridView>
I would like to capture ContactID as follows. I can not do so with out making it visible = true in the GridView.
if (e.CommandName.Equals("Remove"))
{
int index = Convert.ToInt32(e.CommandArgument);
int ContactID = Convert.ToInt32(GridView1.Rows[index].Cells[0].Text.Trim());
}
Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.

I have a dropdown list named "ddlCustomerDatabase' . Now this dropdownlist is associated with a sqldatasource. Now what I want is when there are no values in the dropdownlist ddlCustomerDatabase ie no row in sqldatasource asssociated with it, I want to make it invisible that is ddlCustomerDatabase.visible = False else it should be visible.
I have used IF ddlCustomerDatabase.text Is Nothing THEN,....used IF ddlCustomerDatabase IS Nothing THEN......used IF ddlCustomerDatabase.selectedItem, selectedValue, items.count THEN.. But to no avail.
So what should be the proper logic for achieving my simple goal, to display the dropedown list when it has something else to just make it invisible when it is empty.

Should this be handled in code-behind? (I don't see any ready-made events for paging through the formview) or is there a way to test data and change the visible property in;
<asp:CheckBox
ID="CheckBox3"
runat="server"

View 2 RepliesI have a Save button in my page. When user clicks it, the program will do some checking. If it passes the test, the record will be saved. If not, it will fire another button's onclick event. The 2nd button has been set with both height and width = 0 and it has an extender AJAX ModalPopup.
Here is the code for the 1st button (the visible Save button):

Problem is that setting height and width = 0 for the 2nd button can make the button invisible in IE. But it shows a very small button in Chrome. If I set the 2nd button to invisible, it simply won't function at all.
