Now we can expand/collapsed tree view item using bound read/write model property.

We need to bind read-only property or controll expandability outside of tree view.

Examples:

• Expand tree view item when IsActive read-only model property is true
• Expand/collapse all tree items with a button click

Thank you

When a content is displayed in TelerikWindow and a TelerikTreeView`s item is expanded, the item`s content is above the window one due to higher z-index.

To fix it, use this CSS:

Using your tree view live sample, filter the list with "1", then try to expand "Test1" - crash.

I would expect "Test1" to apprear in the list but without the expandable icon or the expandable icon does nothing when clicked

Hello,

I have updated Blazor UI to the latest version (2.9.0) and some of my controls lost their state.

Let me explain:

I have a page with 4 tabs (TelerikTabStrip), if i choose the value of a dropdown (TelerikDropDown) in the first tab and move to the second tab and then come back to the first tab, the value would be lost and the dropdown is empty however, if i put a breakpoint and look at the model, it shows that the value is still preserved.

Is there something i am missing? is this an update gone wrong (on my side)?

I have downgraded back to 2.8.0 and it works as expected.

Thanks.

Hi,

the Blazor form controls like DropDownList & ComboBox have a fixed width of 300px (why ???).

This does not respect the Boostrap 4 style guidelines and in a <form> looks like:

where the "Currency" field is a standard <select> and "Model Reader Engine" is a <TelerikDropDownList>.

If I try to set the "Width" attribute of the DropDownList to "100%" the result is:

but if I try to open the DropDown the element list is large as the entire screen:

Have you planned a fix for this ?

Thanks in advance

A text/ html editor similar to asp.net core

What about supporting INotifyCollectionChanged data source for the Grid?

How can I show/hide or enable/disable a GridCommandColumn (e.g. Edit) per row.
For example, if a row is readonly, I don't want users to be able to click the edit button. There is no @context inside <GridCommandColumn>

Sample usage

<GridCommandColumn>

    @{

         var item = context as TheItem;
         <GridCommandButton Command="Edit" Icon="edit" Enabled="@!item.ReadOnly">Edit</GridCommandButton>
     }

</GridCommandColumn>

In data grids it can sometimes be quite helpful to be able to export the content for use outside of the application.

In these cases it can be common to export to CSV or PDF.

It would be helpful to have a TreeGrid control which is quite similar to a data grid however it allows hierarchy relationships among the items.

This would essentially have all the features of the standard data grid however one column would be expandable.

Hi,

Ran in to an issue here. To avoid modals getting hidden behind animation containers, we use a class for a div and "wrap" the modal in providing it with a higher z-index than the animation container(s).

However, when using a DatePicker inside this module the calender will be hidden behind the modal (since it is in an animation container).

Any suggestion how to overcome this problem?

Thanks & br,

Please add a PDF Viewer blazor component!

For the meantime: Could you provide an example of how to use the Telerik UI for net core PDF Viewer in a NET core 3 Blazor app?

I want to prevent users without WriteAccess to see the GridCommandColumn and a custom GridColumn containing some buttons.

Those two columns are the first in my grid.

If I add AuthorizeView tags like this

<AuthorizeView Policy="MyPolicy">

   <GridCommandColumn ...>

      ...

   </GridCommandColumn>

</AuthorizeView>

<AuthorizeView Policy="MyPolicy">

   <GridColumn ...>

      ...

   </GridColumn>

</AuthorizeView>

they will be hidden if the user does not comply to the policy but if he does comply the columns are displayed not as the first columns in the grid but as the last.

As a workaround I now don't hide the columns but their content (by moving the AuthorizeView tags inside the column tags).  This is not a good solution though since I loose valuable horizontal screen-space for displaying empty columns.
