Hello DollyB,

Here is an example – if a cell value is less than 5, the cell cannot be edited. You can write a condition of your choice.

Thank You.

I face one more issue now. I set one of the column cell as dropdownlist when I try to edit the cell.
I get this.listbox is null or not an object message when I click on dropdown. The dropdown is set for few cells itself.

Could you tell me why I am getting this message and why I am not able to see the dropdown for few cells?

var reqJsonAttrTemplate =  eval('(' + '<%=sJsonTemplate%>' + ')');	
var keys = [], props = [], rangeValues = [];		
		var dataf = [];
		var row = {};
		var i = 0;
		row["text"] ="name";
	    row["datafield"] ="name";	       
	    row["columntype"] = 'textbox'; 
	    row["width"] =  100;   
		row["pinned"] =  true;	 
		row["editable"] =  false;      
	    reqGridColumns[i] = row;		
		
		for (var attribute in reqJsonAttrTemplate) {		
			i++;
			row = {};
			props = 	reqJsonAttrTemplate [attribute];
			rangeValues = props["Range Values"]; 
			row["datafield"] = attribute;
			row["text"] =  props["Caption"];     //attribute +"["+props["Caption"]+"]";
			
			//Column Type Validation
			if(props["Integer"] == "true"){	
				alert('Integer: '+attribute);
				row["columntype"] = 'numberinput';
				row["initeditor"] = function (row, cellvalue, editor) {editor.jqxNumberInput({decimalDigits: 0, digits: 3});};				
			}else if(props["Date"] == "true"){				 
				alert('Date: '+attribute);
				row["columntype"] = 'datetimeinput'; 
			}else if(props["Range Use"] == "true" && props["Range Multiple"] == "false"){				
				alert('RangeUse and Multiple: '+attribute);
				row["columntype"] = 'dropdownlist';
			}else{				
			alert('Else: '+attribute);
				row["columntype"] = 'textbox'; 
			}
			row["width"] =  200;
			if(attribute == "Alias Tag"){
				row["editable"] =  false;
			}
			
			
			
	        reqGridColumns[i] = row;
}
 // initialize jqxGrid Requirements
            $("#jqxgridDR").jqxGrid(
            {
                width: 700,
                source: reqDataAdapter,
                editable: true,
                pageable: true,
				editmode: 'dblclick',
                autoheight: true,
                theme: theme,
                selectionmode: 'singlecell',
                columns: [                  
		  			{ text: 'name', datafield: 'name', columntype: 'textbox', width: 100, pinned: true, editable: false }                
                ]
            });	    
            // change columns collection. Requirments
            $("#jqxgridDR").jqxGrid({ columns: reqGridColumns });

And my JSonTemplate data looks like,

{
“RTC ID”:{
“Admin”:”false”,
“Force Modify”:”false”,
“Caption”:”RTC ID”,
“Description”:”Description11″,
“Alias Tag”:”false”,

“Subset Master”:”false”,
“Sequence Order”:”0″,
“Date”:”false”,
“Sort Order”:”61″,
“Mandatory”:”false”,
“Locked”:”false”,

“Sub Category”:{

“Force Modify”:”false”,
“Caption”:”Sub Category”,
“Description”:”Description16″,
“Alias Tag”:”false”,
“Subset Use”:”false”,
“Range Values”:”[None, Counter, Event]”,

Hello DollyB,

You can’t set a dropdownlist editor in a such way and only for some of the cells in a column. You can set one editor per column as it is demonstrated in the demos.

Hi,

Even i have the same requirement to disable a cell in the Grid based on its value.

$(“#jqxgrid”).bind(‘cellbeginedit’, function (event) {

// Logic to disable column
});

The above cellbeginedit code gets executed only when there is any change in the row but my requirement is to disable/enable the cell when the whole data gets populated in the grid at the start.

Is this possible ?

Below is the sample code which is not working

if the value is Test1 then the column should be enabled else if Test2 then disabled

var cellclass = function (row, columnfield, value) {

if (value == “Test1”) {
$(“#jqxgrid”).jqxGrid(‘endcelledit’, row, columnfield, true);
}
else if (value == “Test2”) {
$(“#jqxgrid”).jqxGrid(‘endcelledit’, row, columnfield, false);
}
}

$(“#jqxgrid”).jqxGrid(
{
width: 1100,
source: dataAdapter,
columnsresize: true,
sortable: true,
editable: true,
pageable: true,
autoheight: true,
filterable: true,
pagesize: 1000,
enabletooltips: true,
columns: [
{ text: ‘1’, datafield: ‘1’, width: 250, editable: false },
{ text: ‘2’, datafield: ‘2’, width: 100, cellclassname: cellclass, editable: false },
{ text: ‘3’, datafield: ‘3’, width: 100, editable: false },
{ text: ‘4’, datafield: ‘4’, width: 150 },
{ text: ‘5’, datafield: ‘5’, width: 200 },
{
text: ‘6’, datafield: ‘6’, width: 150, displayfield: ‘Region’, columntype: ‘dropdownlist’,
createeditor: function (row, value, editor) {
editor.jqxDropDownList({ source: regionssAdapter, displayMember: ‘REGION_NAME’, valueMember: ‘6’ });
}
},
{
text: ‘7’, datafield: ‘7’, width: 150, displayfield: ‘ECS_GROUP’, columntype: ‘dropdownlist’,
createeditor: function (row, value, editor) {
editor.jqxDropDownList({ source: ECSGroupAdapter, displayMember: ‘Text’, valueMember: ‘7’ });
}
}

]
});

Hello Clarence,

It is wrong to use cellclassname this way. Use the column’s cellbeginedit callback function instead, e.g.:

{ text: 'Product', columntype: 'dropdownlist', datafield: 'productname', width: 177,
    cellbeginedit: function (row, datafield, columntype) {
        var value = $('#jqxGrid').jqxGrid('getcellvalue', row, datafield);
        if (value == "Test2")
            return false;
    }
}

Hi,

In my above example, I need to disable column 6 (displayfield: ‘Region’) on basis of column 2 (datafield: ‘2’).

i.e if Column 2 has value Test2, i need to disable the dropdown of column 6.

Can you please share me the code for the above mentioned scenario.

Thanks.

Hi Clarence,

It should be something along these lines:

{
    text: '6', datafield: '6', width: 150, displayfield: 'Region', columntype: 'dropdownlist',
    cellbeginedit: function(row, datafield, columntype) {
        var value = $('#jqxgrid').jqxGrid('getcellvalue', row, '2');
        if (value == "Test2")
            return false;
    }
},
