Help on checkboxSelection error

[iamgsprabhu]

Hi

I am trying to implement the detailModel:
{ title: "", dataIndx: "selected", width: 30, dataType: "bool", align: "center", type: 'checkBoxSelection', cls: 'ui-state-default', resizable: false, sortable: false },

When I click on the checkbox, it gives me following error as:

"Unhandled exception at line 11754, column 3 in http://localhost/FIStar/Content/pqgrid.dev.js
0x800a138f - JavaScript runtime error: Unable to get property 'pqval' of undefined or null reference
If there is a handler for this exception, the program may be safely continued."

Please let me know how can I fix it.

thx

it is breaking at following function in pqgrid.dev.js file: when I put a break point it show this.$inp as undefined.

_pCheckBC.setValCBox = function() {
    if (!this.hasHeaderChkBox()) {
        return
    }
    var that = this.that,
        options = this.options,
        cbAll = options.selectionModel.cbAll,
        data = cbAll ? options.dataModel.data : that.data,
        val = null,
        selFound = 0,
        unSelFound = 0;
    for (var i = 0, len = data.length; i < len; i++) {
        var rowData = data[i];
        if (rowData.pq_rowselect) {
            selFound++
        } else {
            unSelFound++
        }
    }
    if (selFound == len) {
        val = true
    } else {
        if (unSelFound == len) {
            val = false
        }
    }
    **_this.$inp.pqval({
        val: val
    })_**
};
