Question

Hi I am trying to get showlink formatter working by following this document from trirand.

What I want to achieve is a hyperlink I can click for a edit view to update/edit records. But for some reason, the column are empty where I want show a hyperlink.

Here is my code snippets, and link is the last column:

<script type="text/javascript">
    $(document).ready(function () {
        $("#grid_products").jqGrid({
            jsonReader: {
                repeatitems: false,
                id: 'Guid'
            },
            url: '/Product/jqgridJSON/',
            datatype: 'json',
            mtype: 'GET',
            colNames: ['ProductCode', 'ProductDescription', 'DefaultSellPrice', 'LastCost', 'Edit'],
            colModel: [
                { name: 'ProductCode', index: 'Productcode' },
                { name: 'ProductDescription', index: 'ProductDescription' },
                { name: 'DefaultSellPrice', formatter: 'currency', index: 'DefaultSellPrice' },
                { name: 'LastCost', formatter: 'currency', index: 'LastCost' },
                { name: 'MyLink',
                    edittype: 'select',
                    formatter: 'showlink',
                    formatoptions: { baseLinkUrl: '/Product/Update/', idName: 'Guid' }
                },
                ],
            pager: '#pager',
            rowNum: 10,
            rowList: [20, 50, 100, 200],
            sortname: 'ProductCode',
            sortorder: 'asc',
            viewrecords: true,
            width: 'auto',
            height: 'auto',
            caption: 'Products'
        }).navGrid('#pager', { edit: true, add: false, del: false });
    });
</script>

@{
    ViewBag.Title = "JSONGrid";
}

<h2>JSONGrid</h2>
<table id="grid_products"></table>
<div id="pager"></div>

The formatter from jqGrid is working for currency, but for some reason, it just didn’t shown for hyperlink.

Update:

Got it working by using custom formatter.

...
{ name: 'MyLink',
                    formatter: myLinkFormatter,
                },
...

function myLinkFormatter (cellvalue, options, rowObjcet) {
    return '<a href = "/Product/Edit/' + options.rowId + '">Edit this product</a>';
}

I suppose that you fill no value in JSON input for the 'MyLink' column. Because of this the hyperlink is empty. If you want to place the link with any fixed text in column I would recommend you to use custom formatter. See the recent answer for an example.

One more possible solution way is to use formatter: 'showlink' and include jsonmap: function() { return "Edit"; } to the ‘MyLink’ column definition. In the case you will not need to include in the JSON data "MyLink":"Edit" for every row of data. It’s important to understand that the trick works only in case of usage jsonReader: {repeatitems: false} (so it should work for your grid).

If you have another problem you should include in the text of your question the JSON data which you use.

Some small remarks to your current code:

• the usage of edittype: 'select' together with formatter: 'showlink' has no sense. You should remove it if you will do use formatter: 'showlink'.
• the parameter height: 'atuo' should be height: 'auto'.
• pager: $('#pager') is better to replace to pager: '#pager'. If you use pager: $('#pager'), the jqGrid will replace it internally to pager: '#pager' and the object $('#pager') will be discarded.
• If you use jsonReader: { id: 'Guid'} and you don’t plan to show the guids to the user you can remove the 'Guid' column from the grid. The id (the Guid in your case) will be used to assign ids of <tr> elements (table rows) of the grid. So you don’t need to hold the same information twice
