Asked On July 18, 2019 05:36 PM UTC

My code looks like this:
<EjsGrid GridLines="Syncfusion.EJ2.Blazor.Grids.GridLine.Horizontal" @ref="@FilteredDocList" AllowPaging="true" DataSource="@ViewModel.FilteredDocuments" ModelType="@gridModel">
            <GridColumns>
                <GridColumn Field="@nameof(PartnerPortalShared.POCOs.Document.DocumentName)" HeaderText="Document Name"></GridColumn>
                <GridColumn HeaderText="Expiration Date" >
                    <Template>
                        @{
                            var document = (context as PartnerPortalShared.POCOs.Document);
                            <span>
                                @document.ExpirationDate.ToShortDateString()
                            </span>

                        }
                    </Template>
                </GridColumn>
                <GridColumn Field="@nameof(PartnerPortalShared.POCOs.Document.LocationName)" HeaderText="Location Name"></GridColumn>
            </GridColumns>
        </EjsGrid>


When I run the code I get an error in Visual Studio that states: Warning: Unhandled exception rendering component: Property set method not found.

Any update on this? I half expected to see a release that would have fixed it already :/

I was still getting that error with version 17.2.0.49-beta.  The fix was to not render the grid until the data source was instantiated:

@if (Data== null)
{
     <p>Loading...</p>
}
else
{
     <EjsGrid>
          @* Template Column here *@
     </EjsGrid>
}

@code{

     List<DataType> Data;

     protected override async Task OnInitializedAsync()
    {
        Data = await LoadData();
    }
}

Hi Ryan, 

Query: “I was still getting that error with version 17.2.0.49-beta” && The fix was to not render the grid until the data source was instantiated: 
 
At our end, Grid is rendered properly when we update the Grid DataSource in asynchronous way with read only properties. To replicate your reported scenario, we have prepared a sample to render Grid with empty dataSource and template column with readonly properties. On button click, we have updated the dataSource. We are not able to reproduce the reported issue at our end. Kindly download the sample from below  

 
Kindly refer our model class 
 
public class EmployeeData 
    { 
        public readonly int? EmployeeID = 1001; 
        public string FirstName { get; set; } 
        public string LastName { get; set; } 
        public string Title { get; set; } 
        public DateTime? HireDate { get; set; } 
    } 
 

After referring the sample if you still face the issue, kindly share the following details  

  1. Share the Grid rendering code.
  2. Share your model class of your dataSource
  3. Share the screenshot of script error or exception you are facing.
  4. If possible reproduce the reported issue in the provided sample.
  5. Share the exact details about your issue.

Requested details will be helpful for us to validate the reported issue at our end to provide the solution as early as possible  

Regards, 
Vignesh Natarajan.

17.3.0.28 - Unable to open Grid Template when it's rendered inside EjsModal

Hi Amine,  

Greetings from Syncfusion support.  

Query: “I have also a problem with GridColumn temple, nothing is displayed in the column 
 
From your code example, we have found that you have not defined the ModelType property of EjsGrid. This is the cause of the issue. While using Grid templates like column template, edit template etc. it is necessary to define ModelType with property of DataSource model class. Kindly specify the ModelType property of EjsGrid to resolve the issue.  

Refer our UG documentation and online demo for your reference 




Please get back to us if you have further queries.  

Regards, 
Vignesh Natarajan.
