Column Header Template

Bound columns render the name of the field or their Title in their header. Through the HeaderTemplate, you can define custom content there instead of the title text.

If you only want to center or wrap the column header text, you can achieve that with some custom CSS. You can try one of the following approaches depending on the desired result - Center Grid Column Header content or Wrap and center the Grid column header text.

Sample Header Template

@* Header templates override the built-in title but leave sorting indicators and filter menu icons *@

<TelerikGrid Data="@MyData" Height="300px" Pageable="true" Sortable="true" FilterMode="@GridFilterMode.FilterMenu">
    <GridColumns>
        <GridColumn Field="@(nameof(SampleData.Id))" Title="This title will not be rendered">
            <HeaderTemplate>
                <span>Employee ID</span>
            </HeaderTemplate>
        </GridColumn>
        <GridColumn Field="@(nameof(SampleData.Name))">
            <HeaderTemplate>
                Employee<br /><strong>Name</strong>
            </HeaderTemplate>
        </GridColumn>
        <GridColumn Field="HireDate" Width="350px">
            <HeaderTemplate>
                Hire date<br />
                <TelerikButton OnClick="@DoSomething">Do something</TelerikButton>
                <br />
                @{
                    if (!string.IsNullOrEmpty(result))
                    {
                        <span style="color:red;">@result</span>
                    }
                    else
                    {
                        <div>something will appear here if you click the button</div>
                    }
                }
            </HeaderTemplate>
        </GridColumn>
        <GridColumn>
            <HeaderTemplate>
                <span>
                    <TelerikIcon Icon="image" />
                    Column with Icon
                </span>
            </HeaderTemplate>
        </GridColumn>
    </GridColumns>
</TelerikGrid>

@code {
    string result { get; set; }
    void DoSomething()
    {
        result = $"button in header template clicked on {DateTime.Now}, something happened";
    }

    public class SampleData
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public DateTime HireDate { get; set; }
    }

    public IEnumerable<SampleData> MyData = Enumerable.Range(1, 50).Select(x => new SampleData
    {
        Id = x,
        Name = "name " + x,
        HireDate = DateTime.Now.AddDays(-x)
    });
}
