How can I use the GridView datasource in code-behind to not trim text?

Question

Hi and thanks for looking.

I have a GridView, and its datasource is set to an external class which returns an ArrayList. Now, in the aspx page, I have a TemplateField, and the Text property is set to

Text = '<%#Eval("Name") %>'

except that the Name is always truncated, even though the name in the db has a value much larger. I'm guessing the gridview/databinding is truncating the name for some reason? Anyway, I want to display the full name on hover, so on the _RowDataBound event, I have e.Row.Cells[2].ToolTip = something, and I'm not sure what that 'something' should be.

Can I use Eval in this case, too? And if so, what would the syntax be like? If not, what are my options?

Little playing with CSS and set tooltip will solve this

Code Behind:

   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {   for(int i =0;i <GridView1.Rows.Count;i++)
        {
           Label lblName = (Label)GridView1.Rows[i].Cells[1].FindControl("lblname");
           lblName.ToolTip = "This is my toolTip";//  You can set tooltip as Fullname  
        }
    }

Default.aspx:

   <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" CssClass="gridMyClass"
        Width="125px" onrowdatabound="GridView1_RowDataBound">
        <Columns>
            <asp:TemplateField HeaderText="ID">
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%#Eval("Id") %>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="Name">
                <ItemTemplate>
                  <asp:Label ID="lblname" CssClass="myTxtClass"  runat="server" Text='<%#Eval("name")%>'></asp:Label>

                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

CSS:

.myTxtClass{
    display:inline;
    position: relative;
    text-decoration:none;
    cursor:pointer;
}

.myTxtClass:hover:before{
    border: solid;
    border-color: red transparent;
    border-width: 6px 6px 0 6px;
    bottom: 20px;
    content: "";
    left: 50%;
    position: absolute;
    z-index: 99;
}


.myTxtClass:hover:after{
    background-color: red;
    opacity:0.7;
    border-radius: 5px;
    bottom: 26px;
    color: #fff;
    content: attr(title);
    left: 20%;
    padding: 5px 15px;
    position: absolute;
    z-index: 98;
    width: 220px;
}
