How to resize grid-view column width?

css, gridview, webforms

Solution

dear friend use the following code

    <asp:GridView runat="server" id="testGrid">
    <Columns>
        <asp:BoundField DataField="CustomerID" HeaderText="CustomerID" HtmlEncode="False" ItemStyle-Width="100px" />
        <asp:BoundField DataField="Name" HeaderText="Name" HtmlEncode="False" ItemStyle-Width="100px" />
        <asp:BoundField DataField="Address" HeaderText="Address" HtmlEncode="False" ItemStyle-Width="100px" />
    </Columns>
</asp:GridView>

or if you understand the css then use the following code in which you have to assign the css class to ControlStyle-CssClass property

    <asp:GridView runat="server">
    <Columns>
        <asp:BoundField DataField="CustomerID" HeaderText="CustomerID" HtmlEncode="False" ControlStyle-CssClass="cssclass1" />
        <asp:BoundField DataField="Name" HeaderText="Name" HtmlEncode="False" ControlStyle-CssClass="cssclass2"  />
        <asp:BoundField DataField="Address" HeaderText="Address" HtmlEncode="False" ControlStyle-CssClass="cssclass3" />
    </Columns>
</asp:GridView>

Problem

I am trying to re-size columns width in my gridview that I created using this tutorial, but I am unable to do so. I have been through tens of ways by googling but non of them worked. Code that is creating problem ``` <asp:BoundField DataField="CustomerID" HeaderText="CustomerID" HtmlEncode="False" /> <asp:BoundField DataField="Name" HeaderText="Name" HtmlEncode="False" /> <asp:BoundField DataField="Address" HeaderText="Address" HtmlEncode="False" /> <asp:TemplateField> // I don't want to show it in my gridview as it is just being // for showing nested gridview <ItemTemplate> </td></tr> ``` I tried to change column visiblity but then show/hide button doesn't work anymore. This is how my gridview looks like, I want to hide last empty column or minimize it's width so it should be hidden and increase description column width, decrease ID number column width and also first column's width, I even tried CSS way but then it says width 0px however no change in width and `ControlStyle-Width="10%"` but it didn't worked.
