Hi,
I have a grid form containing only a link component. When a user clicks on one of the rows he gets redirected to the same page(with the ID of the clicked row in the URL). Now I want to dynamically show which was the clicked row by either setting the td - bgcolor to a different color or changing the link color of the appropriate link or (would be perfect) changin the link component to a label component.
The aim is to show the user what cell he has clicked on (this is very often used in navigation headers). How can I make this inside codecharge?
I haven`t found the ability to make anything similar up to know. The component reference does not help very much. Please help.
Code Snippets would be appreciated very much.

Change the control to a label. In the before show row of the grid,
dynamically build a link or display text based on whether a param is passed
to the page and it if matches the id on the current row.

We have various examples on how to use the SetValue function to change control values. For example:
http://docs.codecharge.com/studio/html/QuickStart/EnhAp...FieldValue.html
http://docs.codecharge.com/studio/html/QuickStart/EnhAp...LabelValue.html
http://docs.codecharge.com/studio/html/ProgrammingTechn...ntrolValue.html
http://docs.codecharge.com/studio/html/ProgrammingTechn...eTextColor.html
And even how to change a Grid's cell color as you described:
http://docs.codecharge.com/studio/html/ProgrammingTechn...eCellColor.html
You should be able to use the above code with the CCGetParam function described at:
http://docs.codecharge.com/studio/html/Components/Funct...CCGetParam.html
You'd use CCGetParam to compare a value of a URL variable to the one in your Grid.
I don't program in PHP, but I'm assuming that in the Grid's Before Show Row event you could use the code like:
global $Tasks;
if ($Tasks->Priority->GetValue() == CCGetParam("priority_id", 0)) {
$Tasks->Priority->SetValue("<font color=RED>".$Tasks->Priority->GetValue()."</font>");
}
(I modified the example from the CCS doc at http://docs.codecharge.com/studio/html/ProgrammingTechn...eTextColor.html)
I'm not sure if modifying a Link's value will not cause problems, therefore if it doesn't work then either change the cell color, or add a Label in front of your Link that you can use to display something in front of the link, for example "->".
