If I get a failure during my upload process, how do I show that an error occurred and what it is?

Is there a way to do filtering with check boxes but via LoadSettings? There does not seem to be a property in 'Field' that corresponses to 'Multi'

     Hi

We are trying to create a grid which will have columns added dynamically. Once the grid is bound properly it complaints about not having a default value to the dynamic columns. How can we provide a dynamic columns with default values.

Also we did initialize these values in model constructor, logically those should have been picked up but somehow grid wants explicit default values for all columns.

I would like to merge multiple footer column to get a right-aligned column footer to span or merge a couple columns to the left. I didn't find any post like that in this forum. I came across this approach for Kendo UI for jQuery: https://docs.telerik.com/kendo-ui/knowledge-base/grid-merge-footer-cells

Since it described using styles to achieve the effect of merging footer cells, I figured it would work for Kendo UI for MVC as well. Since I don't want/need any cell boarders in the footer, I set the .k-footer-template td border to none. I put the style block below just after my @model declaration line in the view.

However, the above has no effect on the appearance; I still see each footer cell's border and my sum total of the 4th column (assuming td:nth-child is zero-based) is limited to its cell. Why are the above styles not being applied?

2nd request for help: I want to format the sum total of a column with comma delineated number formatting: #,##0.00 

Here is my client footer template:

As you can see, I ended up using 0,000.00 instead of #,##0.00. The latter works in c# formatting of numeric strings, but I'm guessing the # symbol is interfering with the #= # syntax.  My work-around isn't acceptable as it shows "0," in front of numbers less than 1,000 (e.g., 0,999.99). How can I apply a custom number format such as #,##0.00?

Each user is able to store grid filters in the database as a JSON string for use later.

We now have to iterate through these filters on the server to do some analytics with what the user is filtering the grid on. Is there a way in C# using Kendo.Mvc namespace to deserialize the JSON string stored into the database back into an IList<IFilterDescriptor> Filters?

Hi,

Is it possible to activate the InlineEdit mode when the user clicks on a row? In other words "open" all cells on a row for editing when the users clicks on the row.

It should work the same as when the user presses the update button to call the InlineEdit mode.

When a user presses enter the row should be saved and the next row (if there is any) should be selected and "opened".

I want to simulate (a little) the behavior of a normal winform/silverlight grid.

Is such a scenario possible?

Thanks in advance.
