How to set a value into a cell

A style object holds all the information that affects cells appearance. One property contained in the style object is its CellValue. It is this property that you have to set in order to place a value in a cell. Another property called GridStyleInfo.Text will allow you to set the value of a cell using a string. Text and CellValue are related properties and setting one of these properties will also set the other.

Use two-parameter indexer (rowIndex, colIndex) on your GridControl object to get a reference to that particular cells style, GridStyleInfo object.

//Sets the CellValues of the cell.
int rowIndex = 1;
int colIndex = 2;        
gridControl1[rowIndex, colIndex].CellValue = "PI";
rowIndex++;

//Sets a different value in the next row.
gridControl1[rowIndex, colIndex].CellValue = 3.14159;
'Sets the CellValues of the cell.
Dim rowIndex As Integer = 1
Dim colIndex As Integer = 2
GridControl1(rowIndex, colIndex).CellValue = "PI"
rowIndex = rowIndex + 1

'Sets a different value in the next row.
GridControl1(rowIndex, colIndex).CellValue = 3.14159

NOTE

Using an indexer on the GridControl to set values will trigger several notification events that listeners (and the GridControl itself) can use to monitor the state of the GridControl. These events may slow things down if you have a lot of data to move into the GridControl. In this case, you can want to employ a technique that will avoid these events.

There are several ways to do this; if your data is in some form supported by GridControl.PopulateValues method, you can use that method to move such data into GridControl. Another option is to use GridControl.SetCellInfo method by passing its appropriate parameters to avoid the notification events. But, if you are only setting a few values or you need the notification events to be raised, then using an indexer will accomplish this task.
