[Yogesh SinghParticipant]

Hi i am getting the below error when grid is binding for second time although it displays correctly
this.colmnheader is null or not an object

Hi Yogesh Singh,

Could you give a sample which demonstrates this with jQWidgets 3.1.0?

Thanks for quick reply Peter
Here’s what i am trying to accomplish
I need to show a pop window based on number records returned by the data adaptar and the function in which i have has adaptar grid and condition to check on the length of the adaptar to open a popup first time it work fine second time it gives me error on the below line in the jqxgrid.js file

var i=this.columnsheader.find(“#columntable”+this.element.id);
and once i ignore this error it works fine and it only throws error once when i am reloading a grid for second time

function lookupSearchResultGrid(source, columns,fieldName) {

var searchViewGridDataAdapter = new $.jqx.dataAdapter(source);

$(“#divLookupSearch”).jqxGrid(
{
width: ‘100%’,
source: searchViewGridDataAdapter,
theme: theme,
sortable: true,
pageable: true,
autoheight: true,
selectionmode: ‘checkbox’,
columns: columns
});

var value = columns[1].dataField;
if(searchViewGridDataAdapter.records.length!=1)
{
$(“#popupWindow”).jqxWindow(‘show’);
ShowSearchFieldsLabel(fieldName);
if($(‘#divLookupSearch’).jqxGrid(‘getselectedrowindexes’).length > 0)
$(“#divLookupSearch”).jqxGrid(‘clearselection’);

$(“#txtId”).val(“”);
$(“#txtName”).val(“”);
}
else
{
AddNewFilter(searchViewGridDataAdapter.records[0],value);
$(“#txtValue”).val(“”);
}
};

Is there any better approach to implement this scenario
I am using jQWidgets 3.0.4?
Awaiting your reply

Hi Yogesh Singh,

To update the Grid’s data you should set its “source” property to a new DataAdapter instance, or if you want to use the same dataAdapter, just call “updatebounddata”.

Peter,

I have a text box in which user enters data to search and on button click i populate grid the search result and based on the returned result set length i have to display the grid with search result in a popup
so for first time it works fine but i am not displaying grid in popup based on condition but in the second time it gives me the above error this time grid will be shown in popup even i am just displaying the same grid with another search result
i am passing column array to grid’s column property since based on search type i need to display different columns
it doesn’t break the UI it displays the grid properly when i go ahead and ignore the error.
and its only replicable in the scenario which i have mentioned otherwise it works fine

Hi Yogesh Singh,

If you want to dynamically update the Grid’s source, you have to dynamically set its “source” property.
