RadGrid - Checkbox column - databound - get + set value via javascript

[Chris]

Hi,

 

I have a databound radgrid and I need to get and set the value of a checkbox column client side.

I'm using the following for the other columns, which I have adapted from code found on this site.

 

    var myMasterTable = Grid.get_masterTableView();
    var myCell = myMasterTable.getCellByColumnUniqueName(myMasterTable.get_dataItems()[myRowIndex - 1], ColumnName);
    var myCellValue = myCell.innerHTML;
    if (myCellValue == " ") { myCellValue = ""; }
    return myCellValue;

 

But unlike the other columns it returnsthe below html and not the actual value?

"<span class="aspNetDisabled"><input id="grid_Properties_ctl00_ctl04_ctl50" type="checkbox" name="grid_Properties$ctl00$ctl04$ctl50" checked="checked" disabled="disabled"></span>"

 

How do I get the checked state and also set the checked state via javascript? Is their abuilt in method for this?

 

Thanks in advance

Hi Chris,

The value of the GridCheckbox column is not set as text of the column like in the data bound columns but is used as a value for the underlying checkbox.

You can access its value through the checked property of the input element:

                 var myMasterTable = Grid.get_masterTableView();
                 var myCell = myMasterTable.getCellByColumnUniqueName(myMasterTable.get_dataItems()[myRowIndex - 1], ColumnName);
                 var myInput = $telerik.$(myCell).find("input")[0];
                 var myCellValue = myInput.checked;
                 //test myInput.checked = false;
                 if (myCellValue == " ") { myCellValue = ""; }
                 return myCellValue;
