Hi,

I have a razor page that implements a grid. I want to use javascript to set / unset the dirty markers for certain fields in the grid when there is an error.

I have searched this forum and google'd the problem, but I cannot get anything to work.

I tried :

• setting .dirty to true
• addClass("k-dirty-cell")
• grid.refresh() after setting the dirty markers

Tried these suggestions:

• How to see dirty flag on the cell after change cell's value programmatically? in UI for ASP.NET MVC | Telerik Forums
• reviewed examples from github

Can I please get a simple example of when the on error fires the js function runs and marks / unmarks a cell dirty and the grid reflects those changes?

Here is a simplified example from a different post:

        function onError(e) {
            // got any error messages
            if (e.errors) {
                e.preventDefault();
                var grid = $("#grid").data("kendoGrid");
                var data = grid.dataSource.data();

                for (var i = 0; i < data.length; i++) {

                    data[i].dirty = true;
                }
                grid.refresh();
            }
        }

Thank you for your help.

Good day,

How do I validate the content of a file on the upload event?  I want to read the contents of an excel file and get a distinct list from one of the columns.  Thank you.

Hi,

I would like to know if it is possible to Bind a Grid to a property of an object which is a list of primitive type (i.e. a List<string>).

My ViewModel is something like that:

public class ExampleViewModel
{
   public SomeType { get; set; }
   public SomeOtherType { get; set; }
   public List<string> SomeValues { get; set; }
}

And I imagined I could build the grid like that:

Html.Kendo().Grid<string>(Model.SomeValues)
   .Name("SomeValuesGrid")
   .Columns(columns => columns.Bound(x => x))

As you understand, it would be a very simple grid consisting of only one column, with each row displaying one of the string values.
Is it possible, or can grid only work with objects and not with primitive types?

If I do that, it is to keep the Kendo's grid visual style, instead of manually writing and styling a table.

Thanks for your help.

Hi! I want to disable aria-pressed when I click on the button in buttons group.

Hello Everyone,

I want to display on a gridview data from a table A with cardinality 1-N with several tables (B,C,D, E ..) . I want to display all table data (A,B,C,D, E ..) with a condition : to have exactly one line for each data from table A. the data from tables B, C, D … I want to display them as many columns, and iterate as long as I have data.

How can I achieve this? I thought of Pivotgrid but that does not answer exactly what I ask?

Please fined in attach what’s the grid should look like.

PS: i need also to export the Grid in an Excel file .

Thank you  .

Hi,

is it possible to have the grid save on leaving a row, and omit most of the buttons like 'Save' or 'Edit'?

We'd like the grid to do as much as possible automatically without the user having to trigger each function/event manually...

AutoSync(true) doesn't work for us, because it collides with our required fields, and always fires validation errors with each change of a cell value.

We tried this solution, but it doesn't cover all the bases: https://www.telerik.com/forums/auto-save-row-when-moving-to-the-next-row 
For example a record is not automatically saved, if it is the only one in the grid, because the solution requires to click another row.
Also the Delete-Event is not fired until another row was clicked.

I'd wish this was a standard feature for the Telerik Grid, because I have seen other vendors where their grid works like this by default, no scripts or whatever required.
