I'm sorry if this is already ask but i cant find similar topic.
I try to make show/hide column similar to this React (forked) - StackBlitz using checkboxes.
When i select all false, instead of all column dissapear, it will render all field of the Grid data object.
For example you can set show: false on every column in columns state in React (forked) - StackBlitz

First state when only 2 column shown

When all column show property set to false

Is it a bug or just the grid works?

I have setup a listening event on the page:

And setup the column widths to use a percentage of the window size.

When the window increases in size it works and when I decrease it back to the point of the original window size it works.  It does not seem to work when I reduce the window below the original width it does not appear to work.

I am using Typescript and I have implemented a select column (check box select column) using the GridColumn and adding a "selected" property to each object in the array that is being bound to the grid (much like the example shows in the docs).  Everything works great until I group by a column.  At that point, I get a warning that is coming from one of the telerik js files (column file):

Warning: A component is changing a controlled input to be uncontrolled. This is likely caused by the value changing from a defined to undefined, which should not happen. Decide between using a controlled or uncontrolled.

While this is just a warning and it goes away when using the production build of react, it is still something we would like to try to eliminate if possible.  Has anyone else experienced this warning before and is there any solution for it?

I have KendoReact Editable Grid with  below Columns 

If Lastname and firstname exists 100 how to show error message on top of grid as validation summary, Please suggest.

Hi Team,

Control : numeric text box

How to restrict the user from entering negative value. 

If we set min value as min={0} it is allowing user to enter negative value and then on focus out it is reverting the value to min that is "0". Our expectation is  hard restriction by not allowing to enter the negative value.

I'm, surprised we don't have keyup and keydown events for numeric text box

When I am adding a new row to the bottom of the grid ,  scroll bar(grid) is automatically moving to top, but it should scroll down,. Please help me to resolve this issue.

Thanks,

Arun

Hi Team,

We are using numeric text box in our application and facing issue in below scenario.

Step 1 : user entered the value 1.85 in the numeric text box.

Step 2 : Focus out the numeric text box

Step 3: Now Focus the numeric text box and press Ctrl + A to select the all the value and Now enter “.85” using keyboard then the expected result is “.850” should be entered in the numeric text box. But it is taking the input as “85.00”

Please refer the below image for reference.

Hi,

I noticed that the value of all DropDown components can be cleared with the inline clear "button", but not the DropDownList. Is there any way to get the same consistent behavior for the DropDownList so that it's inline with the rest of the DropDowns?

versus:

To be clear, I know that I can reset it by setting the value to "null", but I want to be able to do it via a "x" button.

Hi there,
