I need to change back color of cells when the data is bound but don't want to display the data.

[M]

Hi, 

i've a grid with cells in a time interval of 15 mins. It's a 24 hours cycle.I'm trying to change the color of the cells based on the start and end time.

the cells should be coloured from start to end time.

Also I need to count the shaded cells per column and display it on a footer. 

please can someone suggest how can I achieve this functionality? 

Thanks

Hello,

To achieve this requirement, you can traverse the cells on ItemDataBound event handler and set their BackColor property depending on your specific condition:

For calculating and displaying the content of the highlighted cells on the footer, you can use both server and client-side approach. I believe these resource will prove helpful:

Hope this helps.
