How to change column width for gridview

This sounds very simple but I'm kindof at my wits end with it.  I have a gridview in which a new column was added thats causing it to look too wide on my web page.  All of the columns are asp:BoundField.  Here is what I have tried to no avail.

1) Changing the item style width for the columns
2) Changing the header style width for the columns
3) Changing the control style width for the columns.
4) Changing the width of the entire grid view.
5) Changing the width of the container inside of the gridview.
6) Moving the gridview outside of the container and making the width smaller.
7) Placing the gridview inside of a div and styling that to an arbitrarily small size.


None of  these seem to effect the width of it.  This is very weird to me.  I seem to be able to effect the width of the content inside of the column but not the column itself.  I can't figure out anywhere in the code that is making the column as wide as it is.  I've attached an image of the gridview as is.  Right now, the entire gridview is sized to an arbitrary small width, the columns are all sized to a smaller width and it is inside of a container that is sized to an arbitrary small width.  All of these seem to have no affect.  It is still too wide.

Any ideas?  Am I missing something simple?

Thanks in advance!

Did you try these 2 together?
1) Changing the item style width for the columns
2) Changing the header style width for the columns
all you need to set the header size for each column

it can be fixed number or %

example for asp page :
 
 <asp:BoundField DataField="Status" HeaderText="Status" ReadOnly="True" SortExpression="Status" >
            <HeaderStyle Width="10%" />
            </asp:BoundField>

<div style="width: 200px;">            
            <asp:GridView ID="gvPolicyData" runat="server" OnRowDataBound="gvPolicyData_RowDataBound"
                OnPageIndexChanging="gvPolicyData_PageIndexChanging" AutoGenerateColumns="False"
                 Height="160px" AllowSorting="True" BorderStyle="None" CellPadding="5" Width="50%">
                <Columns>            
                    <asp:BoundField DataField="Policy_ID" HeaderText="Policy_ID" SortExpression="Policy_ID"
                        Visible="False" />
                    <asp:BoundField DataField="Policy_TEXT" HeaderText="Text" ReadOnly="True">
                        <HeaderStyle BackColor="#DFDFDF" Font-Bold="True" ForeColor="Navy" VerticalAlign="Bottom" Width="5%"/>
                        <ItemStyle Width="5%" />
                        <ControlStyle Width="5%" />
                    </asp:BoundField>


None of these things seem to be making any difference.

I think the weird thing is that the column information will wrap and resize but the column itself won't.  As an example heres PART of my code for this gridview setting the grid at a particular size inside of a div that is a particular size and a column set at a particular size.

        <asp:GridView ID="gvPolicyData" runat="server" OnRowDataBound="gvPolicyData_RowDataBound"
                OnPageIndexChanging="gvPolicyData_PageIndexChanging" AutoGenerateColumns="False"
                 Height="160px" AllowSorting="True" BorderStyle="None" CellPadding="5" Width="50%">
                <Columns>            
                    <asp:BoundField DataField="Policy_ID" HeaderText="Policy_ID" SortExpression="Policy_ID"
                        Visible="False" />
                    <asp:BoundField DataField="Policy_TEXT" HeaderText="Text" ReadOnly="True">
                        <HeaderStyle BackColor="#DFDFDF" Font-Bold="True" ForeColor="Navy" VerticalAlign="Bottom" Width="100px"/>
                        <ItemStyle Width="100px" />
                        <ControlStyle Width="100px" />
                    </asp:BoundField>

Attached is the picture of what that looks like.

Ok, so heres what the problem was.  In my gridview some of the databound columns contained long links or other text without spaces.  This causes the word wrap to not wrap and pushes the whole column out despite what size I specify.  So what I had to do was add some spaces in those long sequences of text to force a word wrap.  Now it is sized properly.
Hi from 2018. Thank u so much! I killed 3 hours to solve that stupid problem.
