Set ReadOnly Property With CheckBox Value

I want to set a textbox's ReadOnly value to the OPPOSITE value that the
CheckBox has. For example: If the user checks the CheckBox then the
ReadOnly property for the TextBox is set to False. The default value of
the TextBox is set to false. Am I on the right path or am I totally
off in left field?
<input type="checkbox" name="chkCode1" value="ON"
onclick="docume nt.DisplayCodes .txtGrossPayrol l1.readOnly !=
document.Displa yCodes.chkCode1 ">
<br>
<input type="text" style="text-align: right;" size="10" tabindex='1'
readonly="true" name="txtGrossP ayroll1" value="0" width="10"
onkeyup="Comput ePremium(1)" onkeypress="ret urn blockNumbers(ev ent)"/>
Thanks,

I've gotten a little closer, but no completely. Instead of using the
ReadOnly property I tried the Disabled property. When I put a check in
the checkbox, the disabled property is set to false, but if I uncheck
the checkbox, the textbox is not disabled. Can someone tell me what
I'm missing?

<input type="checkbox" name="chkCode1" value="ON"
onclick="docume nt.DisplayCodes .txtGrossPayrol l1.disabled=
!document.Displ ayCodes.chkCode 1" />
<br>
<input type='text' style='text-align: right;' size='10' tabindex='1'
disabled='true' name='txtGrossP ayroll1' value='0' width='10'
onkeyup='Comput ePremium(1)' onkeypress='ret urn blockNumbers(ev ent)'/>

Thanks,

Well:
<input type="checkbox"
onmouseup="this .form.txtGrossP ayroll1.readOnl y!=this.checked " />
<input type="text" style="text-align: right;" size="10" tabindex='1'
readonly="true" name="txtGrossP ayroll1" value="0" width="10"
onkeyup="Comput ePremium(1)" onkeypress="ret urn blockNumbers(ev ent)"/>

Thanks for everyone's help. I was able to get it to work correctly by
referring ot ASM's example.

I came up with:
onclick="docume nt.DisplayCodes .txtGrossPayrol l1.disabled =
!(this.checked) ;"

Thanks again!

Hi Group, I have a checkbox column in a web datagrid which is related to a "Product in stock" property. The grid is in view mode, so the user can't (and shouldn't) change anything in the grid. What I need is to show a "ReadOnly" checkbox in the grid, but not a disabled one (grayed out). I'm using a template column and the only property I can set is "enabled".

Hi everyone, I'm not entirely sure if this is the best way of going about it, but here's the scenario.......... I have two datagrid, each bound to a datatable which have checkbox columns. There are two buttons between the datagrids, "Add" and "Remove". They basically remove rows from one grid to the other, only those with the checkbox ticked.
