I have a asp Gridview and need to fix 1 columns width see below


                                                  Need to fix Note Column Width to at least Half of displayed Note Column

Watch Question


you can set the Width property of a particular field,
but if you want to set it as a proportion of the max width, then you need to do postprocessing of the gridview display event

Hi Robr
I Tried setting width as below, where do you set it, its not in the Gridview edit columns
width 100px gives error in aspx file
<asp:BoundField DataField="Id" HeaderText="Id" SortExpression="Id" ReadOnly="True" Visible="False" />
                        <asp:ButtonField ButtonType="Button" CommandName="Selection" HeaderText="Option" Text="Selection" />
                        <asp:BoundField DataField="Note" HeaderText="Note" SortExpression="Note" Width="100px"/>
                        <asp:BoundField DataField="RemDays" HeaderText="Days" SortExpression="RemDays" />
                        <asp:BoundField DataField="RemDate" HeaderText="Date" SortExpression="RemDate" DataFormatString="{0:dd/MM/yyyy} "/>

and Last Display rtyrtyudtyudtyudtyudtyudtyudtyudtyudtyudty is same

<form id="form1" runat="server">
        <asp:SqlDataSource ID="dsNotes" runat="server" ConnectionString="<%$ ConnectionStrings:SchoolDataConnectionString %>" SelectCommand="SELECT [Note], [RemDays], [RemDate], [Id] FROM [SchoolNotes]"></asp:SqlDataSource>

        <asp:GridView ID="gvDesc" runat="server" AllowPaging="True" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="Id" DataSourceID="dsNotes" ForeColor="#333333" GridLines="None" PageSize="4" ShowHeaderWhenEmpty="True" Style="overflow: scroll; z-index: 1; left: 16px; top: 83px; position: absolute; height: 157px; width: 390px" SelectedIndexChanging="gvDesc_SelectedIndexChanging">
            <AlternatingRowStyle BackColor="White" />
                <asp:BoundField DataField="Id" HeaderText="Id" ReadOnly="True" SortExpression="Id" Visible="False" />
                <asp:ButtonField ButtonType="Button" CommandName="Select" HeaderText="Option" Text="Select" />
                <asp:TemplateField HeaderText="Notes" SortExpression="Notes" ItemStyle-Width="30em">
                        <asp:TextBox CssClass="inp" ID="TextBox7" runat="server" Text='<%# Bind("Note") %>' Width="20em" Wrap="true"></asp:TextBox>
                        <asp:Label ID="Label8" runat="server" Text='<%# Bind("Note") %>' Width="20em" Wrap="true"></asp:Label>

                    <ItemStyle Width="6em"></ItemStyle>
                <asp:BoundField DataField="RemDays" HeaderText="Days" SortExpression="RemDays" />
                <asp:BoundField DataField="RemDate" DataFormatString="{0:dd/MM/yyyy} " HeaderText="Date" SortExpression="RemDate" />
            <EditRowStyle BackColor="#7C6F57" />
            <FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#E3EAEB" />
            <SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True" ForeColor="#333333" />
            <SortedAscendingCellStyle BackColor="#F8FAFA" />
            <SortedAscendingHeaderStyle BackColor="#246B61" />
            <SortedDescendingCellStyle BackColor="#D4DFE1" />
            <SortedDescendingHeaderStyle BackColor="#15524A" />



to get wrap to work the way you want (it is working, but only on space), i think you may need to use a disabled multiline text box, not a label.

Thanks Robr
Multiline works but don't really want vertical slide bars
Found this was set to 2 % adjusted it to 0.6 % ( Original Code) and it gives the correct height for multiline data but too small for any data depending on width see image 1st, 2nd, 4th Lines OK  3rd line height incorrect
if there code like ( suggested Code) or can i do it on dataBinding in VB.net
is there Suggested Code 

if Eval("Note").ToString().Length < 350 Height= 18px, Height=Eval("Note").ToString().Length * 0.6& 
Original Code

<asp:TextBox TextMode="multiLine"  Width="400" Text='<%#Eval("Note") %>' Height='<%# Eval("Note").ToString().Length * 0.6%>'  ID="TextBox9" runat="server"></asp:TextBox>

No the panel just displays over top of other databound will work with having slid bars that good
