Hi,

For my Kendo Grid, I'm looking to implement generic action methods such as what is described here:

Thanks

Hi, i am using the kendo grid, with many columns, all of them filterable. For the filtering i use the columnMenu. One filter is working fine. But if i put a second filter in it, it has some issues. Do i filter from right to left (start setting filters on the right of the table) and adding more filters from left side, it works too. But if i start filtering in the first column from the left and then add more of columns that are more on the right, i get 0 items back ... 

If i click now the most left filter again, i just click filter again, it works. 

I am searching for hours, but the queries are the same , just the order i insert the filter seems to make problems. Any suggestions ? 

Hello guys,

I'm interested if it's possible to override the current search panel function, mostly for two reasons:

1. to call the function on click, not keyup event
2. to prevent existing filters from being deleted?

Thanks.

The Date value submitted to the Controller method from the DateRangePicker control is not compatible with the System.DateTime .NET Type.

DateRangePicker:

Initialize Script:

onDateRangeChange:

Grid Definition:

gridGetData:

Controller:

Attempt1:

Populate grid, initialize with DateTime parameter type

See attached files: 

- Annotation 2020-05-05 1.png - This is what happens the first time the grid.Read method is called

- Annotation 2020-05-05 alert.png - This shows the same alert from the gridGetData method 1st attempt then after the onDateRangeChange is called.

onDateRangeChange:  Nothing.  The Controller is not called

Attempt2:

Populate grid, initialize with string parameter type

I changed the Controller.IndexJson method's Parameter from DateTime to String DataType

At this point, the gridGetData successfully fired the Controller method and the string value given matched what was on the "Annotation 2020-05-05 alert.png" right side.  On DateTime.TryParse, the value was not compatible with .NET.

Thanks in advance for your help,

I just managed to get the upload control working with a razorpages app, using what I already knew about conventions etc.  Having replaced the use of Save with SaveURL, passing in the name of the handler, but it would be nice to have just a few notes on each control for Razorpages-specific implementation help.  I seem to recall reading this was "in the works".  Just curious if there is a planned date where we might see this?

Seeing this example, how can I pass along extra values in the data that is posted back to the server, along with the file(s)?  Custom model?

Is there a way to force the TextBoxFor component to honour the data annotation string/max length for a model property?

I have the following model property with a data annotation for StringLength.

I'm using the TextBoxFor component in a view.  But it will NOT enforce the maximum string length during data entry.

In order to get the TextBoxFor to restrict the maximum string length, I have to add the @maxlength property myself.

Is there a way to have the TextBoxFor enforce the string length based on the data annotation itself?

Thanks.

When I choose the export button enabled in options only the first page exports.  I am using scrollable() in the configuration.

Is there a way to export it natively to export all rows?

Thanks

When given a legit value on startup, value is not represented.

Sometimes I forget the Razorpages is MVC under the covers. Having the need to build single-page app/responsive type web apps, I chose the following approach, and here is how the guts of the solution is laid out I setup for our team:

Web
- This is the main web app which includes an API
Models
- This project simply holds POCO classes that are passed
Data
This project holds classes that wrap Entity data models with methods for saving/fetching etc
The api uses methods in the classes of this project but accepts & returns objects of types from the Models library

The basic approach is when using controls on a page, eg.  some dropdowns, a grid etc
- Initial loading of the user input controls via Ajax calls to the api
- Typically there is one main task on a page, but other things have to be loaded at different times in order to get to the point of doing the main edit/update
- Once the user inputs are provided, the data for the grid can be fetched (via jquery/ajax call to api) and the grid loaded
- jQuery code that is common to doing much of the api calls are setup in a common js library

The great thing about this approach is that it handles 99% of what we need and I don't have to replicate the model classes in something like Typescript or javascript as with other frameworks.  The same POCO classes can be referenced both in the api and the razor code.  Anyone that has had to replicate models i=from C# into Typescript knows what Im referring to. Yes, I had started out pushing our team to use Angular and we went down that road for over a year.  It works, but was overkill for what we need. The "noise" of the various frameworks like Node/NPM and including it within a asp.net core app and the dependencies it has on the build process etc was just too much "noise".  So along comes Blazor but alas it wasn't production-ready at the time we needed it.  Using Razor pages with the above architecture lets one accomplish much of what one would want from a framework like Angular with a far simpler development stack.

hope this helps
