How to overwrite certain cell in data grid if it's already filled with text?

Hi.

Datagrids are complex. Changing the value of a "cell", whether already containing data or not, is not as straightforward as doing so in a field.
There are two ways, and you should read about each in the DG User Guide. Check out the "dgData" and the "dgText" properties. Write back if you have problems.

I sugget you to read this: http://livecode.wikia.com/wiki/Datagrid_API
It contains all properties and hidden functions to work with datagrid.
A lot of them aren't in the dictionary.

1. If you need to do it manually, then you can simply double-click on the cell (in a datagrid "table") and edit it.

2. If you need to do it by script, use either setDataOfIndex or setDataOfLine command, directed at the datagrid.
If you are giving this command from outside the datagrid script, then send this command by using DISPATCH or SEND.
For example, where tParameterList is a comma-separated list giving the values: pIndex,pKey,pValue

The above commands are described in the datagrid user guide (link given in an earlier message on this thread).

either setDataOfIndex or setDataOfLine command, directed at the datagrid.

Sri is correct if you only want to change a single "cell" or a single line. Do practice all the suggestions. You will surely use them all.
