Hi,

I am trying to do something simple but having trouble.

All I want is a grid that displays columns for a name and an IsActive property. 

I tried using:

<GridCheckboxColumn Field="@(nameof(AppRole.IsActive))" Title="Is Active"/>

but got nowhere with it.

The basic code is show below. How can I center the checkbox in the column and make not editable unless the are in edit mode?

Also, I want the checkboxes centered in the column.

Any help would be great.

 

Thanks … Ed

 

         <TelerikGrid Data=@GridData
                       Pageable="true" Groupable="true" Sortable="true"
                       OnUpdate="@UpdateHandler" OnDelete="@DeleteHandler" OnCreate="@CreateHandler" OnEdit="@EditHandler">
              <GridColumns>
 
                  <GridColumn Field="Name" />
                  <GridColumn Field="@(nameof(AppRole.IsActive))" Title="Is Active">
                      <Template Context="ctx">
                          @{
                              var r = ctx as AppRole;
                              var chk = r.IsActive ? "checked" : "";
                               <input type="checkbox" checked="@chk" />
                           }
                      </Template>
                  </GridColumn>
                  <GridCommandColumn Width="300px">
                      <GridCommandButton Command="Save" Icon="save" ShowInEdit="true">Update</GridCommandButton>
                      <GridCommandButton Command="Edit" Icon="edit">Edit</GridCommandButton>
                      <GridCommandButton Command="Delete" Icon="delete">Delete</GridCommandButton>
                      <GridCommandButton Command="Cancel" Icon="cancel" ShowInEdit="true">Cancel</GridCommandButton>
                  </GridCommandColumn>
              </GridColumns>
              <GridToolBar>
                  <GridCommandButton Command="Add" Icon="add">Create Role</GridCommandButton>
              </GridToolBar>
          </TelerikGrid>

Hi Ed,

The GridCheckboxColumn is used only for row selection, not for data binding/display.

To display and edit boolean data, you need to use the standard GridColumn. When bound to a boolean field, it displays True/False as text by default (example here) and if you want something different, you need to use a template, as you have found. If you want to center the contents, add a div element around your custom checkbox and style those two elements as desired. To prevent editing, simply disable the checkbox in the Template.

Just a note on the template. I found out that the next code works better to set the value of the checkbox in the grid:

@{
var r = ctx as AppRole;
<input type="checkbox" disabled @bind=r.IsActive />
}

Here's what I did recently:

        <GridColumn Width="50px" Field="@(nameof(PicklistValueInfo.IsActive))" Title="Active">
            <Template Context="ctx">
                @{
                    var r = ctx as PicklistValueInfo;
                    <TelerikCheckBox Enabled="false" Value="r.IsActive" />
                }
            </Template>
         </GridColumn>
