May 7, 2015

I am trying to figure out a way to change the color of the text display in a label control or span inside a user control. The text needs to be displayed in a different colour based on the value returned.

<asp:Label ID="NameLabel" runat="server" Text='<%# Eval("Name").ToString()=="Flying Bats" ? "Display the text in green" : "Display the text in red" %> '/>

The text value would be one of the two. The font color needs to be ether red or green based on whats been returned.I cannot figure out how to do it.

Forms Data Controls :: Read The Background Color Of A Row In A GridView?

Jul 16, 2010

I have a GridView. In my RowDataBound event I add attributes for the mouse onclick event, which sets the row's background color to red when the row is clicked. This works. I have a button outside of the GridView. When I click this button, I want to read each row of the GridView, and if its background color is red I want to perform some processing on the row. I tried the following code and even when the row's background is red, I cannot get its background color (bgc is empty).

I'm trying to make a page, with a textbox, and a linkbutton. In the textbox you can enter any hex colour code you want, then you can click the linkbutton and the pages background will change to that colour. But I don't want the page to postback.
