Kendo grid  Issue while doing  server side paging and client side sorting ,filtering  in dot net core mvc 

      Me.FoodlistTableAdapter.Fill(Me.ITEMMASTERDataSet.Foodlist). login failed for user stores sql exception

Hi all,

 

I am using Kendo UI with Angular. I want to show some data in my Kendo Grid but I am stuck at a point as the json data I am using is of multiple level.

Json data:

{

"colleges": [

{

"id": 1,

"name": "test 1",

"entities": [

{

"type": "teacher",

"name": "Dan"
}

]

},

{

"id": 2,

"name": "test 2",
"entities":

[

{

"type": "student",

"name": "David"

}
]
}

],

"status": "Success"

}

 

I want to show data in the below form:

 

College name            Student name                  Teacher name

test 1                                                                          Dan

test 2                            David

 

Your valuable response will be appreciated. Please feel free to contact back if any question.

 

Thanks,

I am using a radgrid which has edit form for each row. When I click on the EDIT, needdatasource event is triggered and databinding, which I dont want it to do because the query for the grid takes a fews seconds to run. I set on the needdatasource event so that the code doesn't run if the EDIT link is clicked on. But this makes the radgrid disappear. I have tried making the grid visible again and enable but doesnt show the grid. Code snippet below.

 protected void rg_OrderSummary_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
                if (refreshGrid)
                {

                    (sender as RadGrid).DataSource = LoadResults();
                }
                else
                {
                    rg_OrderSummary.Visible= true;
                    updGrid.Update();
                }
            }

}

How can I get it the grid to show without having to run databind again through need datasource event please?

 

                             

using (var memoryStream = new MemoryStream(bytes))
                {
                    using (var workBookImporter = SpreadImporter.CreateWorkbookImporter(SpreadDocumentFormat.Xlsx, memoryStream))
                    {
                        foreach (var worksheetImporter in workBookImporter.WorksheetImporters)
                        {
                            int rowCounter = 0;
                            foreach (var rowImporter in worksheetImporter.Rows)
                            {
                                if (rowCounter < skipHeaderRows)
                                {
                                    rowCounter++;
                                    continue;
                                }
                                var county = rowImporter.Cells.ElementAt(6).Value;
                                counties.Add(county);
                            }
                        }
                    }
                }

worksheetImporter.Rows only ever contains the first row of the spreadsheet. I tried downloading the same bytes to a file, and the other rows are there.  Is there an issue with the library?  I used this a couple weeks ago and it worked fine, but now it's broken.

I have an MVC 3 application that has been running well so far on a Windows 2012 web server. We are in the process of upgrading the application, AS IS, to a Windows 2022 server. And are running into the following error:

 

 

[ArgumentNullException: Value cannot be null.

At this point, I am fairly certain this has to do with some dll mismatch between the 2 servers. The 2022 server has MVC3 installed on it.

Any ideas what I should be looking at?

My understanding is if you had a license at the time a project was built then you could always use that version, is this still true? I need to make a couple small edits to a legacy asp.net MVC app that was built when I had an asp.net controls license for version 2021.2,511 but I no longer have the license as I now only have a license for the Blazor controls.

I've switched machines since then and am therefore unable to build the project without restoring the packages from the telerik nuget feed. I understand I cant upgrade to a newer version but just need to make a few minor edits that have nothing to do with the telerik controls in the project. How can I restore the packages in this project so it can build?

Thanks.

Is it possible to get the psd file for the Loading animation image used with callbacks?

I would like to use a different background color than white.

Thanks.
