jdforce | Hi,
I am getting a JSON with a TServerRequest, in the Complete Event. Then I load the JSON to a dataset on the dataset.loadrows method. Then dynamically I fill a grid, column by column with the data like so: grid1.columns[0].header.caption := 'Device ID'; grid1.columns[0].dataColumn := 'deviceid'; grid1.columns[0].width := 80; It works good, but I want to change the color for a row according to the value of one of the fields. The change of color of course must be paired with the value if I click on the column title to sort up or down. I have not found a way to accomplish this, and need some example or suggestion please.

In addition to Tim's hint, here a sample how to read the cell's data within the OnCellUpdate event: if ACell.Data = '0' then begin ACell.Font.Color := clRed; ACell.Font.Style.Bold := true; end else begin ACell.Font.Color := clBlack; ACell.Font.Style.Bold := false; end; Uli |
