Hi there,

I'm having an issue getting the grid with client detail template to work.

My Parent grid model and child grid model both have a property named ConditionAssessmentId. However, when expanding the detail template, the read action always fails with the following error:

I do note that it does correctly resolve the same binding expression in the Name property of the child grid, just not for the Read event.

Am I doing something obvious wrong here? I've referred to your DetailTemplate example and can't see anything I am doing differently.

Thanks,

Paul

When using clasic ASP.NET Core approach user can define custom editor template like this:

Hello,

I have multiple grids inside Panelbar, for some reason filter popup window doesn't show up in the usual place (below filter icon) but right in the middle or in extreme cases even at the top of the window.

Thanks.

Dear,

I want to Add dynamic & cascade dropdown in filter control in .NET CORE but current it allows only one dropdown in Filter Field. 

Below is the screen shot attached "Payout Rule - 6.png" what actually I want to achieve. Is there any way to customize this control in .NET CORE so kindly share. 

Hello,

I've done some searching  and can't find an example of this, so I'm asking here...

I have a grid that I'm using as part of a process to build a parent with child objects.  Think Order (as the parent) and Products (as the children).  Each parent has one or more children.

I create the parent object, and then 'Add' children to it, one at a time.  This part works great.

I would like to be able to upload a file as part of the process or creating a child.  I only need to upload one file at a time, and only when I create the child.  

I'm using Asp.Net core 2.0, with Telerik UI version 2017.3.1206.

I don't have a small project to demonstrate this; I could build one if I needed to, but it would take a bit.  I'm  just hoping for some pointers to documentation, or examples.  

Thanks!

Phil

What is the proper location to post issues with the on demand courses?
Looking at the Telerik UI for ASP.NET Core course, comments are rarely responded to.

I'm trying to work through it but encountered an issue and can't really proceed with the course.  Made a comment but I'm not sure anyone is really looking at them.

Based on dates displayed in the examples, the course was recorded in 2019 so I'm sure a number of changes have taken place since then.

Thanks,

Here is the scenario:  I have a grid that is set to GridEditMode.InCell and Batch=true.  I can make changes to up to 15 records in the grid, click save and the data posts back to the controller without issue.  However, if I update greater than 15 records and click save, the postback to the controller works but the data is null.  

I hope that this isn't a product limitation and I've verified that data being posted back is less than the limit of Json serializer.   

A few caveats to my issue:  

1. We have purchased the licensed version, but have not gone through internal channels to actually access the licensed version so I am still using the trial version.  Is it possible that the trial version has a limitation like this?

2. The grid is a nested hierarchical grid and the data being updated is nested 3 deep.

3. While the grid doesn't display all the data, each record being posted back contains a nested json object (see example of data below).  Because of configurable business requirements, the structure cannot be flat.

Any help would be appreciated. Specifically, knowing the save/update method in kendo code that is being called for batch saves with InCell mode.

Here is my grid (higher level nesting is omitted for simplicity):

Here is my controller that works fine when less than 15 records have been updated (some security logic has been omitted to avoid potential confidentiality issues), but the key is that both the request object and the agents object are fully populated when less than 15 records:

Here is what 1 record of data looks like:

Going through and testing the Kendo grid functionality. I created a new Telerik project using the menu and grid template.

.NET Core 3.1

Telerik.UI.for.AspNetCore (2021.1.224)

I can get my test data to load on the grid no problem, however when ever I enter text in the search box, it gives an "Input string was not in a correct format" exception on the server side. I've noticed, that if a defined column is bound to a string typed property, the search filter works fine. But if I have a int (or DateTime for that matter) typed property, that's when I get the exception. For example, in my object I have an ApplicationId property. If I exclude it in the .Columns definition of the grid, everything works fine, however if I include it, that's when the ToDataSourceResultAsync() method seems to choke, and I get the exception. Probably something dumb, but I can't seem to find what I could be doing wrong.
