Good Afternoon,

A few days ago I created this thread on setting the grouping for a grid on initialization and received an excellent solution from Marin Bratanov.
https://www.telerik.com/forums/can-i-set-grid-grouping-and-collapse-on-initialization

Now I am trying to generate multiple grids in a loop for each election race in my list. I was successfully able to do this by creating a local variable and grabbing only the specific race entries with a linq query. All of this works fantastically.

 

@foreach (VotingMainModel item in ElectionState)
            {
                if (item.OfficeName != OfficeName)
                {
                    <br />
                    <br />
 
                    <h6>@item.OfficeName</h6>
 
                    IEnumerable<VotingMainModel> electionFilter = ElectionState.Where(x => x.OfficeName.Equals(item.OfficeName));
 
                    <TelerikGrid Data="@electionFilter" Groupable="true" @ref="@GridRef" FilterMode="@GridFilterMode.FilterMenu">
                        <GridAggregates>
                            <GridAggregate Field="@(nameof(VotingMainModel.Votes))" Aggregate="@GridAggregateType.Sum" />
                        </GridAggregates>
                        <GridColumns>
                            <GridColumn Field="@(nameof(VotingMainModel.OfficeName))" Title="Office" Groupable="true" />
                            <GridColumn Field="@(nameof(VotingMainModel.Candidate))" Title="Candidate" Groupable="true" />
                            <GridColumn Field="@(nameof(VotingMainModel.Affiliation))" Title="Affiliation" />
                            <GridColumn Field="@(nameof(VotingMainModel.Precinct))" Title="Precinct" />
                            <GridColumn Field="@(nameof(VotingMainModel.Votes))" Title="Votes">
                                <GroupFooterTemplate>
                                    Total Votes: <strong>@context.Sum</strong>
                                </GroupFooterTemplate>
                            </GridColumn>
                        </GridColumns>
                    </TelerikGrid>
                    OfficeName = item.OfficeName;
                }
            }

 

However, I would like to also set the grouping automatically for each table generated. When I get to the OnAfterRenderAsync method I get an error that says "The render handle is not yet assigned" Can I have multiple tables reference the same grid reference if they are the exact same grids with just different data in the tables?

Can I make and assign local gridref variables to each grid..I did try this, but it simply did not group them. I also tried making a list TelerikGrid and tried to add a new TelerikGrid and set the state in the loop this also really didnt do anything.

protected override async Task OnAfterRenderAsync(bool firstRender)
       {
           if (firstRender)
           {
               {
                   await GridRef.SetState(GetDesiredInitialState());
 
               }
               this.StateHasChanged();
           }
       }

Good Afternoon,

 

I am building an elections app. I would like to use the Telerik Grid to display the candidates and votes. Each candidate will have a table row/record for each precinct vote tally. I have set the ability to group and to group by the candidate column. However I have to click/drag manually to group the candidates.

 

What I would like is when the page loads is a listing of each candidate grouping with a footer of the total vote count in a collapsed state. Then the user if they want to see a breakdown of the votes by precinct, they can expand the candidate.

 

Can I setup the grid to do be in this state programatically? If so, can you get me pointed in the right direction?

Below is my grid

<TelerikGrid Data="@officeList" Groupable="true" >
                                    <GridAggregates>
                                       <GridAggregate Field="@(nameof(VotingMainModel.Votes))" Aggregate="@GridAggregateType.Sum" />
                                    </GridAggregates>
                                    <GridColumns>
                                        <GridColumn Field="@(nameof(VotingMainModel.Candidate))" Title="Candidate" Groupable="true" />
                                        <GridColumn Field="@(nameof(VotingMainModel.Affiliation))" Title="Affiliation" />
                                        <GridColumn Field="@(nameof(VotingMainModel.Precinct))" Title="Precinct" />
                                        <GridColumn Field="@(nameof(VotingMainModel.Votes))" Title="Votes">
                                            <GroupFooterTemplate>
                                                Total Votes: <strong>@context.Sum</strong>
                                            </GroupFooterTemplate>
                                        </GridColumn>
                                    </GridColumns>
                                </TelerikGrid>

I have a scenario I did not see how to fix.  I have a menu aligned top right with sub menus.  It expands down and then to the right.  The sub menu items on the screen edge stay on the screen but cover the menu items underneath.  Is there a way to expand to the left?

Im using a code-behind approach as in this article
https://www.telerik.com/blogs/using-a-code-behind-approach-to-blazor-components

When using the upload component, we need to specify a SaveUrl
https://docs.telerik.com/blazor-ui/components/upload/overview

Is that the only way? 
Can we have a web api that and a blazor server app in the same project, with the api handlers handling routes also?

Hi,

How do I make all/some Check Boxes selected on Grid Load?

Is there "Value" or "Selected" property of that component?

Something like:

                        <GridColumns>
                            <GridCheckboxColumn Selected="true"/>

                       </GridColumns>

Please advise

I installed UI for Blazor into an existing Blazor Server project. I have confirmed that the Telerik control for Blazor are functioning with my pages. However, when using the controls on a Razor page I am not getting any Intellisense suggestions. If I do CTRL + Space Intellisense displays "No Suggestions". Have I missed a setup step or something?

Thanks.
