you can bind gridview with blank dataset or datatable.
Then show only gridview column.
Set the property of grid view ShowHeaderWhenEmpty="true".
And then
bind the empty dataset or datatable to gridview.
GridView1.DataSource = dt;
GridView1.DataBind();

I'm trying to manage the checkall control in a gridview but I'm facing several problems.
This is my gridview control:

First problem:
The checkbox controls are dynamically created and I honestly have the feeling that I should create an event handler for those, but I don't know how to do it nor I know where to put/write that code. I just see those controls are not recognized once I try to reference them in my code.
Second problem:
Since I'm pretty much a newbie, I made a step back and tested with some junk code if I was able to have all the checkboxes dinamically checked at page load... here is my test... the result a complete failure, nothing happens. I even tried to put the code in the init event, but the result is the same.
For Each row As GridViewRow In gvShow.Rows
DirectCast(row.FindControl("chkCheck"), CheckBox).Checked = True
Next
I would be grateful if anyone could help me with these problems.
Thanks in advance for your time.

I have found the answer myself. I had to change the code as follow:

Next
End Sub

in visual basic, I'm trying to capture the selected date and place that info in a label, but haven't been able to yet. any suggestions? I have this:
Protected Sub LinkButton1_Click(sender As Object, e As EventArgs) '(sender As Object, e As DataGridCommandEventArgs)
Label1.Text = GridView1.SelectedRow.DataItem
End Sub
clearly, I'm missing something, any help is appreciated. Also, please let me know if I can post this question more effectively.
thanks!!
You need to use the property Value, and perhaps use the ToString method.
GridView1.SelectedRows(0).Value.ToString()
I have a gridview on my webpage with one of the columns as a "Reference Number". The reference number represents the name of a pdf file on the server. Is it possible change this column to a hyperlink column so that when they click on the Reference Number on the row it opens the pdf? For example they click on ReferenceNumber 123456 and it opens up the pdf \server\folder\123456.pdf. Thank you

You need to change the Reference Number field to a TemplateField instead of a BoundField, this will allow you to put a hyperlink into that field.
Read Using TemplateFields in the GridView Control
From there, I would suggest using an HttpHandler to build the PDF file and stream it to the user. This has two benefits:
There is no postback, so the user does not lose their place in your grid display.
It allows the user to easily view and/or save the PDF separate from you application.
I have a command field in a gridview, that as it is, works as it should. When i select it, the row is hilighted. However, i needed to convert this field into a template, so i could give it a ID that i could reference when using a AJAX Mobal control. I did this, and i am able to reference it with my Ajax control just fine, but, now this field does not select the row in the Gridview? The Select value is needed for the Ajax control to pull the data thru. So i think my issue is, How do i use this command field as a template, AND have it select the row? I hope i am explaining my issue correctly.
Here is the snippet of code when i convert it into a template.
Thank you!

That is the grid, here is the function...
Sub resetSelect(ByVal s As Object, ByVal e As DataGridCommandEventArgs)
lblResponse.Text = [want to access text of username here]
lblResponse.Visible = True
lblID.Text = dgResetPassword.DataKeys.Item(e.Item.ItemIndex)
End Sub
How do I reference the selected items DataField text for username?
username is in the 3rd column. So you can do this (C#):
lblResponse.Text = e.Item.Cells[3].Text;
This will be the VB.net way of doing it.
lblResponse.Text = e.Item.Cells(3).Text
It may be beneficial for you to set up an enum that represents the columns and their indices. As such your code wiould become
lblResponse.Text = e.Item.Cells(DataColumns.Username).Text
