I am using a hierarchical grid as per your demos for ASP.NET Core.  When I call the hidecolumn() js function like so:  
       $("#CategoryGrid").data("kendoGrid").hidecolumn("Category4");, it does work as expected, but only for the Chrome browser.  Firefox and Edge display a huge column size for the leftmost column with the expand button created by the hierarchical grid, (with the header class 'k-hierarchy-cell k-header').  When a column is removed in chrome the remaining column sizes expand uniformly, but in firefox and Edge, the leftmost column expands at a much faster rate, which will then shrink the rightmost columns with the actual data to below their minimum sizes.  Is there an easy fix for this?  

Thank you.

Hello, 

I have a grid that I would like to work with an html form.

Right now the form an grid work just fine. What i am trying to do is pass parameters to the method that runs the actual query. When I add in the parameters that is when the issue arises, instead of the results going back into the grid i get a page of json results. Any help would be greatly appreciated.  

@(Html.Kendo().Grid<MVCPROJECT.ViewModels.FormViewModel>()

                  {

                      columns.Bound(c => c.LastName).Width(120).Filterable(ftb => ftb.Multi(true));

Hello,

It seems that there is no Extension method in Kendo.Mvc.Extensions for MVC Core to use Dynamic Grid with DataTable?

"DataTable" does not contain a definition for "ToDataSourceResult", and the overloading of the optimal extension method "QueryableExtensions.ToDataSourceResult (IEnumerable, DataSourceRequest)" requires an IEnumerable

how to use a datatable in ASP.NET MVC Core Version of the grid?

I have a RadGrid that's losing the ability to sort columns by clicking the column header. I've narrowed it down to some code in my ItemDataBound method that updates the header text. If I remove this code, clicking the column headers works properly. But when I put it back, sorting is disabled. 

Here's my grid:

Here's my ItemDataBound method:

Any idea why this is happening?

Hello,

I have an application that has many different tables that need to be presented to the user - some of these have over 200k rows of data.

We currently use a very bad and basic search feature, along with .skip(x), .take(x) to only get a certain amount of data per page.

What I do above works, but lacks more advanced filtering.

I'm currently evaluating and looking at grid, but, I am very confused - it supports paging and by increasing the sample app to return 200k items, I can see through network monitoring that it only pulls the single page at a time, however, I'm getting lost trying to evaluate this product...

... The docs don't seem to go in to that much details and the demos page seems to be better, but neither give any information about performance tuning, limiting the result set and similar - I'm worried that if I link this to the live data, I'm going to introduce a lot of problems.

Are there any other documentation bits that I am missing?

1.when i change the Brower width, the text auto wrap and the row height grow. I want to set the text not wrap(see attachment), how can I do that.

2.I want to set text wrap in edit mode, how can I do that?

I am attempting to call a function in the controller when the Destroy button is clicked on a row. The controller will then delete the record in the database. I also need to pass in the ID of the employee to identify which record in the database to delete. Thank you!

This is what I have:

Hi there,

I am using a simple Kendo grid which contains a pop up form to allow a user to either add or delete new "categories" (many) for one product.

popup

I have altered the pop up to contain an additional "delete" button. As this extra button is not supported by the grid's inbuilt update function, I have used AJAX to capture data within the pop up held in a form and return it to the controller's separate "delete" method.

The pop up form code is contained on a partial view that looks like so:

And just for reference, the "Product" model like so:

I've added the delete button by using the grid's edit event to add the button dynamically via JavaScript:

So, when the user selects a category, they have the option to either add or delete a category from the selected "product". However, where "add" is handled by Kendo, I need to handle delete using AJAX.

The delete button is linked to the following JavaScript.

And the corresponding Controller method like this:
