How to make a particular editable in a list grid keeping other rows uneditable?

[AkashMohapatra]

Hello Sir

I am using Smart Client V10.0 for my project. I have been stuck in a phase where I need to make all rows un editable except one which I select through the checkbox. I have pasted the code below. I will really appreciate if you can give me a helping hand in this.

Code:

departments: isc.ListGrid.create({
ID: "departmentsID",
width: 550,
height: 150,
canEdit: true,
editEvent: "click",
modalEditing: true,
selectionType: "single",
alternateRecordStyles: true,
showEmptyMessage: false,
selectionAppearance: "checkbox",
fields: [
{name: "description", type: "text", canEdit: false},
{name: "view", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == false) {
departmentsID.setEditValue(item.rowNum, 2, false);
departmentsID.setEditValue(item.rowNum, 3, false);
}
}
},
{name: "copy", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == true)
departmentsID.setEditValue(item.rowNum, 1, true);
}
},
{name: "edit", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == true)
departmentsID.setEditValue(item.rowNum, 1, true);
}
}
]
}),
/*

Here, I want the particular row (which row is selected through checkbox(the one in bold in code) ) to be selected keeping other rows of list grid non editable. I will appreciate your help. Thanks!

You can override canEditCell() and only return true for selected records - for example, you could check grid.isSelected(grid.getRecord(rowNum)).

I re-wrote the code as suggested. But, I am getting an error "unable to get property rowNum" when I trying to multiple boxes in the selected row. Screenshot is attached to support.



Code:
departments: isc.ListGrid.create({
ID: "departmentID",
width: 550,
height: 150,
canEdit: false,
editEvent: "click",
modalEditing: true,
selectionType: "single",
alternateRecordStyles: true,
showEmptyMessage: false,
selectionAppearance: "checkbox",
fields: [
{name: "description", type: "text", canEdit: false},
{name: "view", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == false) {
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 2, false);
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 3, false);
}
}
},
{name: "copy", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == true)
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 1, true);
}
},
{name: "edit", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == true)
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 1, true);
}
}
],
canEditCell: function(rowNum, colNum) {
if (departmentID.isSelected(departmentID.getRecord(rowNum)) == true) {
return true;
}
else
return false;
}
})

You just need to set canEdit:true on your grid, instead of canEdit:false

It got solved! Thank you sir! But, is there a bug in Listgrid field type "boolean" while toggling.It always shows the above error when I am clicking the checkboxes of "view" or "copy" or "edit"

code:

departments: isc.ListGrid.create({
ID: "departmentID",
width: 550,
height: 150,
canEdit: true,
editEvent: "click",
modalEditing: true,
selectionType: "single",
alternateRecordStyles: true,
showEmptyMessage: false,
fields: [
{name: "description", type: "text", canEdit: false},
{name: "view", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == false) {
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 2, false);
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 3, false);
}
}
},
{name: "copy", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == true)
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 1, true);
}
},
{name: "edit", type: "boolean", width: 70,
changed: function(form, item, value) {
if (value == true)
wildware.EditUserWindow.departments.setEditValue(item.rowNum, 1, true);
}
}
]
})

Thank you again!

item.rowNum isn't valid - try item.getGridRowNum()
