I am trying to display a column from a database table in the column of a datagrid. I am using a template column to display it.
There are two things that are important to me:
1. If DataItem.TtlInf o is too many characters to be completely seen I want "..." to be added as the last three visible characters in the control. Then, the user can view the entire varchar by mousing over (hence the tooltip).
2. I would prefer to use a label because the TextBox display looks ugly. Unfortunately, I use a TextBox now because the label won't allow me to limit the characters displayed.
So, does anyone know of a nice way to display a limited amount of character in a label control? And if the 'text' property is larger than the set amount of characters, then "..." will be concatenated at the end of the visible area (for display purposes only). Then the tooltip could be used to view the entire string. - <asp:TemplateColumn ItemStyle-Width="250px">
-
<ItemTemplate>
-
<asp:TextBox ID="txtTtlInfo" runat="server" CssClass="contentblack" ToolTip='<%# DataBinder.Eval(Container,"DataItem.TtlInfo") %>' Text='<%# DataBinder.Eval(Container,"DataItem.TtlInfo") %>' TextMode="SingleLine" ReadOnly="True" width="225px" Height="20px"></asp:TextBox>

</ItemTemplate>

In the method that handles your Gridview's RowDataBound event, check the the length of the string in the cells that you want to truncate...if they're longer than the length, truncate them and add "..." instead.
I'm not sure how you would go about adding the value to the tool tip though...
Unless you set the tool tip when you are creating the datasource for the GridView...

Frinny, I got it. Thanks a lot for the help. - <asp:Label ID="lblTtlInfo" runat="server" CssClass="contentblack" Text='<%# (DataBinder.Eval(Container,"DataItem.TtlInfo").ToString().Length > 40) ? String.Concat(DataBinder.Eval(Container,"DataItem.TtlInfo").ToString().Substring(0,40), "...") : DataBinder.Eval(Container,"DataItem.TtlInfo") %>' Tooltip='<%# DataBinder.Eval(Container,"DataItem.TtlInfo") %>' >

Hello
Is there an equivalent of a OnTextChangedEvent for a asp: label
control in asp.Net 2.0. Every time the text of a label changes, I
want
the items in a listbox control cleared.
Tried doing as textbox and gave the ReadOnly="True" and border=0 to
mimic a label control, but since the Readonly is set to true, the
"OnTextChanged" event does not get fired.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
