Hello,
Thank you for contacting us.

I manage to look at the sample that you send to us, and the behavior that you are experiencing is because of the default behavior of the html elements when you set a title attribute over them. So in order to be able to overcome this I recommend you to use our igxDialogTitle directive. This is your  sample with the applied necessary changes in order to see the tool tip only over the title of the dialog ng5_2D00_ig_2D00_dialog.zip.

If you need any further assistance, please contact us.

Hello,
Thank you for contacting us.

I am sending you a small example in order to see in action how you can change the button label dynamically. About your second question: the dialog component by default there is no tool tip added over any of it's element, so in order to be able to help can you please give me more detailed information about your case or you can apply the necessary corrections over the example that I send to you below and send it back to me.

I am looking forward to hear back from you, and also if you have any additional questions, please contact us.

Hello,
Thank you for contacting Infragistics Support.

Currently, we do not provide a way to set a custom classes for specific row, so it is not possible to set a style to specific row based on particular cell value (I guess by column value you mean cell value), you can only define a custom template  and style for a specific cell. If I did not correctly catch up your case please provide more detailed information about it in order to be able to help you. You can also log an issue as a feature request in our GitHub repository and we will review and start work on it as soon as possible.

If you need any further assistance, please contact us.

Hello,
Thank you for contacting us and for the provided detailed information.
As I explained to you in the previous comments the grid height is calculated base on number of records in your data source, rowHeight and when the grid height is set in '%',  it is calculated base on the parent container height. So when your data is initially empty the grid is sized according this conditions, and it can not be resized again correctly when your data arrives, because all the necessary calculations have been already made. Here you can see related issues to yours 1858 , that has already been addressed and here you can see the solution which is going to be implemented in out next major version.

To sum up, what I can suggest to you as a temporary solution is the following:

if its absolutely necessary to set the height in '%', you can bind the grid to array of empty objects like in the example  and another way is, as you have already noticed, to set the grid height in pixels.

If you need any further assistance or questions, please contact us.

Hello,

Thank you for contacting us.

In Igx-Grid in order to have a vertical or horizontal scroll the virtualization should be enabled so I strongly recommend you to read the articles that I sent to you in the previous comment. Also I am send you a small example where the igx-grid is defined with width in '%'  and the vectical scroll is enabled.

Please let me know if you have additional questions.

Hello,

Thank you for contacting us.

Vertical scroll in IgxGrid depends on the grid height, rowHeight and the number of records in your data source. If its necessary to set the height '%' in order to enable virtualization the number of records that you have in the grid and their rowHeight have to exceed the height the grid. Here you can read more detailed explanation about how the virtualization works and here you can see more information about the grid properties.
