I have created application .NET Core 3.x using razor pages. I am not sure how to binding works for the Igrid. Could you help me with binding works on this.
It's my cshtml.cs
public async Task OnGetAsync()
Role = await _context.Role
.Include(r => r.App).ToListAsync();
//GridModel gridModel = new GridModel();
//gridModel.ID = "grid1";
//gridModel.DataSource = _context.Role.AsQueryable();
//var paging = new GridPaging();
It's my razor page cshtml
column.For(x => x.RoleId).HeaderText("RoleId").Width("30%");
column.For(x => x.Description).HeaderText("Description").Width("30%");
I am currently working on preparing a sample, demonstrating databinding to igGrid in .Net Core application. I will keep you posted on my progress and I will get back to you soon with more information. Please feel free to continue sending updates at any time.
After investigating this further, I determined that a model for the data could be created by adding a class to the project. The data for the model is defined in a method “GetRoles” in the Index.csthml.cs file and called in the “OnGet” method the following way:
public void OnGet()
Roles = GetRoles();
The model is bound to the igGrid as follows:
. . .
Below I am attaching a sample, demonstrating the described behavior. Please test it on your side and let me know if you need any further information regarding this matter.
Thank you. I could be able to build the application without an issue but the grid is empty. I have see the role count is 12 from my context but the grid is empty when there’s .DataSourceUrl(Url.Action("GetRoles")) But returning error when using .DataBind()
Fixed the model null value error but the Infragistics grid is empty.
Binding the data to the grid by using .DataBind() is working on my side, without any errors. Could you please send me a small isolated sample, demonstrating the problem, which occurs by using .DataBind(). Having a working sample on my side, which I can debug, is going to be very helpful in finding the root cause of this behavior.
Thank you for your cooperation. Looking forward to hearing from you.
I tried to upload the project file (zip) but I don't see it here
I can't open your sample project in VS2019. I am creating project in VS2019
I followed your code and copied your code to the index model but the grid is not showing on the page. After Welcome the page is empty
A possible reason for this exception could be if jQuery is loaded more than once within the application. Please keep in mind that by design the template for a Razor pages project has references for jQuery scripts in the _Layout.cshtml file. What I could suggest is removing the following lines of code from the _Layout.cshtml in the “Shared” folder:
<script src="~/js/site.js" asp-append-version="true"></script>
After removing the scripts, the grid should be rendered and populated with data by using .DataBind().
Additionally the system has rejected the project because of its size. If they are still problems with binding data to the grid, what I could suggest is uploading the project to a drive and sending me a link for the project.
