I am using the Grid Control and when I click on a cell it changes color, but, does not retain/display the data input into it. The two editable column are the two custom columns. One has Javascript the other does not. Neither one works.

The Javascript:

function on_begin_edit(cell)
{
//Get the current cell value
var v = cell.getValue();

//Use index 0 if there is no value
if (v == null){
v = 0;
}
document.getElementById('TextBox1').value = v;
}

function on_end_edit(cell)
{
//Get the current cell value
var v = cell.getValue();
if (v == 0) {
v = null;
}
alert("Got Here");

//Return the new value to the grid
return v;
}



The following is the code for the Grid:

I never see the ALERT("Got Here"). I was just testing the round trip... Values were to follow. What I am trying to do eventually is Click on a cell, enter a number, and have the cell retain that value. I checked the database and it is NOT in read only mode. Neither of the two custom columns show the entered number or keep it. According to the documention Clicking on the cell should put it into Edit mode, unless I a reading the documentation wrong. Also, I added an Alert("Got Her") to the on_begin_edit(cell) and don't get that alert either. Any help in the right direction would be appreciated...

Great answer, really helpfull. I found that if I change the field from a Custom to a Textbox it is now editable. I do lose the ClientSideGetText and ClientSideBeginEdit and ClientSideEndEdit. So my question is:

Is there a way to use ClientSideBeginEdit etc from a TextBoxColumn?

BTW, Samples did not help. Trial and Error worked, but, that's why I asked support....
