Started building my first app with Blazor Grid and running into some issues. Have several columns that need dropdownlist to display text instead of underlying number (eg select and display "Operations Department" instead of value of 3)
The grid will not sort based on the Display Text but does so instead based on value. Same when trying to group using the field. Sort by the value in groups (and I see no way to change the sort order from ascending to descending on the groups too).

Hi,
I'm trying to display the Gantt component as read-only. While it's easy to disable editing for the TreeList that's part of the Gantt component, I can't seem to disable editing of tasks through the timeline. There are 3 things that I'm trying to resolve.
1. How to disable the popup editor when double clicking a task in the timeline?
Only thing I can come up with is hide the popup editor through a css class with 'display: none':
<GanttSettings>
<GanttPopupEditSettings Class="d-none" />
</GanttSettings>2. How to disable dragging of the tasks on the timeline?
I can't seem to find a way to lock the tasks in place. I can always drag them.
I'm aware I can set the start and end values of the task back to the original value after dragging (through OnUpdate), but I don't want to be able to drag them in the first place.
3. How to hide specific editing buttons on the task in the timeline?
When hovering over a task in the timeline it always shows a number of handles or buttons for the following actions (circled in red in the below screenshot):
- change the completion percentage.
- specify new dependencies
- delete the task
How can the handles and buttons for these actions be disabled/hidden?
Kind Regards

1. How can I force sorting it by number and not string?
2. When sorting, can I force one of the row to always be at the bottom? (i.e. if one of the cells includes 'Total' text)

Hi, the standard Blazor programming docs recommend using the @key marker with components that are generated in a loop at runtime, which would be the Grid, TreeList, etc., however, I have not seen this @key marker used in any of the Telerik Blazor demos or sample code. Is setting of the @key marker done automatically by Telerik Blazor for the Grid, TreeList, etc., or is that something we should be doing somehow as we write apps using these components?

Hey!
I searched everywhere but i can't find a solution for my problem.
Im using a TelerikTextBox with Telerik Blazor 2.3 but i upgraded to 3.4 and now you have to use a TelerikFloatingLabel as a parent element for the textbox.
This is my old code:
internal static void CreateLabelTextBox(RenderTreeBuilder builder, int index, string labelContent, string propertyName, object sender, object bindObject, string className, bool isEnabled)
{
builder.OpenElement(index++, "Div");
if (!string.IsNullOrEmpty(className))
{
builder.AddAttribute(index++, "Class", className);
}
builder.AddContent(index++, (RenderFragment)((rBuilder) =>
{
rBuilder.OpenComponent(index++, typeof(TelerikTextBox));
if (!string.IsNullOrEmpty(labelContent))
{
rBuilder.AddAttribute(index++, "Label", labelContent);
rBuilder.AddAttribute(index++, "Title", labelContent);
}
rBuilder.AddAttribute(index++, "id", GetNewId());
if (TryGetProperty(propertyName, bindObject, out PropertyInfo property))
{
var propertyValue = property.GetValue(bindObject) != null ? property.GetValue(bindObject).ToString() : string.Empty;
rBuilder.AddAttribute(index++, "Value", propertyValue);
rBuilder.AddAttribute(index++, "ValueChanged", EventCallback.Factory.Create<System.String>(sender, str => { property.SetValue(bindObject, str); }));
}
rBuilder.AddAttribute(index++, "Enabled", isEnabled);
rBuilder.CloseComponent();
}));
builder.CloseElement();
}
And now im trying to wrap this inside of a FloatingLabel:
internal static void CreateLabelTextBox(RenderTreeBuilder builder, int index, string labelContent, string propertyName, object sender, object bindObject, string className, bool isEnabled)
{
builder.OpenElement(index++, "Div");
if (!string.IsNullOrEmpty(className))
{
builder.AddAttribute(index++, "Class", className);
} builder.AddContent(index++, (RenderFragment)((rBuilder) =>
{
rBuilder.OpenComponent(index++, typeof(TelerikFloatingLabel));
if (!string.IsNullOrEmpty(labelContent))
{
rBuilder.AddAttribute(index++, "Text", labelContent);
//rBuilder.AddAttribute(index++, "Title", labelContent);
}
rBuilder.AddContent(index++, (RenderFragment)((xBuilder) =>
{
xBuilder.OpenComponent(index++, typeof(TelerikTextBox));
//if(TryGetProperty(propertyName, bindObject, out PropertyInfo property))
//{
// var propertyValue = property.GetValue(bindObject) != null ? property.GetValue(bindObject).ToString() : string.Empty;
// xBuilder.AddAttribute(index++, "bind-Value", propertyValue);
//}
xBuilder.CloseComponent();
}));
rBuilder.CloseComponent();
}));
builder.CloseElement();
}
Any suggestions how this might work?
