[Solved] Problems loading a grid from a Partial View

[Paul]

Hello everyone,

Been struggling with this one all day...

I have View containing 3 Telerik grids (all configured for Ajax binding and each rendered by a seperate partial view). The first two grids contain the 'main' data and are used to render the 3rd grid (the 1st and 3rd grid contains the same rows, and the rows from the 2nd grid are displayed as 'dynamic' columns in the 3rd grid - kind of a cross between the first two grids).

When one of the first two grids is modified, the 3rd grid is reloaded by making an ajax call to re-render the partial view.

Everything works fine when the View is initially loaded, however after the Ajax call to re-render the 3rd grid, the fields in the 3rd grid (rendered by Telerik as numerical/currency textboxes) can't be modified and I get the following JS error (in telerik.textbox.debug.js):

Line: 1551
Error: Unable to get value of the property 'value': object is null or undefined

telerik.textbox.debug.js

function evaluator(type) {
    return function (value) {
        $(this).data(type)
               .value(value);
    };
}

View

<div id="ManageLoanPurposeElements">
    @Html.Partial("_ManageLoanPurposeElements",Model)
</div>

JS
Here the OnComplete Event Handler of the second grid reloads the 3rd grid:

function onFinancingElementGridComplete(e) {

    // Update the Loan Purpose Grid
    if (e.name == "delete" || e.name == "insert") {
        $('#ManageLoanPurposeElements').load('./_ManageLoanPurposeElements');
    }

}

I have a feeling I'm having a similar problem to http://stackoverflow.com/questions/10726962/dynamically-loading-a-view-telerik-mvc

Hello Paul,

I am not sure what exactly might throw that error. Could you provide more information how to reproduce the issue on our side? 
Also instead of reloading the whole partial view you could try to reload only the data of the Grid via the ajaxRequest() method.
e.g.
$('#ThirdGridName').data('tGrid').ajaxRequest()

All the best,
