View 2 RepliesMy GridView rows have a field for a server timestamp when a person entered in a particular state(like idle). I want to show the time elapsed since the person has been in that particular state. That I want to show as a tooltip when mouse is hovered over the cell and time elapsed calculation I want to do on client side only without a roundtrip to the server. In RowDataBound event of the GridView I add functions to the show and hide the tooltip by following some examples on the web. In the JavaScipt function, I calculate the time elapsed. But it works first time but not after that somehow and I get a JScript error "Microsoft JScript runtime error: Function expected." on this line:
document.getElementById("td0").innerText = elapsedpretty(timeInState);

I am working on setting up an aspx page using access datasource in web eepression. Access Datasource is having image source information from other resources feed. I am using listview to display all the images.

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.

I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
item.Attributes.Add("title", someotherdatabasefield);
The end result would be something like this where the text for 'title' comes from the database
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>
