[How Do I Prevent A Blank Value From Being Entered In TUniSpinEdit?]

In the desktop demo for Grid - Row Editors, how do I prevent a user from using the keyboard and entering a blank value for the phone extension? Although the TUniSpinEdit control has minimum and maximum values set, these are not respected.

[How To Determine If An Editable Column In TUniDBGrid Is Being Edited Or Not?]

Please see attached video. After I double click the column or press the ENTER key on it, I want the label "Editing: No" to become "Editing: Yes".

If I decide to cancel an edit and I press the ESCAPE key, I want the label "Escape: No" to change to "Escape: Yes" and the label "Editing: Yes" to change to "Editing: No".

Note: I have also attached the testcase file.

[How To Determine If An Editable Column In TUniDBGrid Is Being Edited Or Not?]

I have a editable string column in a TUniDBGrid that is linked to a datasource.

How do I determine that it is in edit mode after I double click it and how do I know that it is no longer in edit mode after I press ESCAPE?

[OnKeyDown Event In TUniDBTreeGrid Does Not Recognize VK_DELETE]

This issue does not seem to have been fixed in UniGUI version 1.90.0.1543?

Thanks for the update.

[OnKeyDown Event In TUniDBTreeGrid Does Not Recognize VK_DELETE]

In the OnKeyDown event of a TUniDBTreeGrid, I have the following code:-

procedure TMainForm.treGridKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
   if Key=VK_DELETE then
      showmessage('here');
end;

The message is not shown when I press the Delete key.

In TUniDBGrid, this works.

How do I get the Delete key to be recognized in the TUniDBTreeGrid component?

Try the following:-

UniMemo1 -> ClientEvents -> ExtEvents ... add Ext.Js event for AfterRender:

function afterrender(sender, eOpts)
{
   sender.bodyEl.dom.addEventListener(
        'keydown', 
        function(e) {if (e.key=='Enter') {e.stopPropagation()}}
    );

[How To Position To A Row And Column For A TUniDBTreeGrid?]

Hello,

You can try this:

TUniDBGrid(UniDBTreeGrid1).CurrRow

 

Thanks. The missing property message is gone but the code does not perform as I would expect.

Please see the attached video. Each time I add a record, the new record is properly positioned to but the rectangular highlight is pointing to another row. I want the highlight to be at the new record.

I have also attached the project files.

Is a solution available?

[Part Of Field Missing In TUniDBTreeGrid When Exclamation Mark Present]

Any solution for this?

[How To Position To A Row And Column For A TUniDBTreeGrid?]

In a TUniDBGrid, I can use the following code to position to a row and column:-

grdGrid.JSInterface.JSCall('getNavigationModel().setPosition', [grdGrid.CurrRow, grdGrid.CurrCol]);

I can't use the same code for a TUniDBTreeGrid because the CurrRow and CurrCol properties are protected. How do I achieve the same result for this component?

[How To Set The Entire TUniDBTreeGrid Row To A Specified Colour?]

In TUniDBGrid, there is a Options.dgRowSelect property which I can use to colour the entire row. In TUniDBTreeGrid, the same property cannot be set at design time. How do I colour the entire row for this component?

[TUniDBTreeGrid Does Not Respect The Sort Order Of A Query]

I have a PostgreSQL query with an "order by shortcode, code" parameter. When a TUniDBTreeGrid's datasource is set to it, the code order is not followed as the query correctly shows.

What could be happening here?

[Part Of Field Missing In TUniDBTreeGrid When Exclamation Mark Present]

I have a PostgreSQL query that contains a column named SortCode with "!Stocks Without Variants" in some rows. When I set the KeyTreeFields of a TUniDBTreeGrid to "sortcode", the part that begins with "!Stocks" is missing.

What can I do to show the entire column content?

I have a TUniStatusbar with 7 panels. One of the panels is supposed to be hidden from view depending on the user's status. Is it possible to hide any panel without deleting it?

[Are The Default Hyperserver Configuration Settings Sufficient For Up To 500 Simultaneous Active Sessions?]

Thanks. It is clear now.

[Are The Default Hyperserver Configuration Settings Sufficient For Up To 500 Simultaneous Active Sessions?]

Thank you for the information

[Are The Default Hyperserver Configuration Settings Sufficient For Up To 500 Simultaneous Active Sessions?]

If that is the case, I suppose that Hyperserver will bump the user to another node once a node's maximum session limit of 250 is reached.

[Are The Default Hyperserver Configuration Settings Sufficient For Up To 500 Simultaneous Active Sessions?]

5 hours ago, Farshad Mohajeri said:

This is the Max sessions for HyperServer itself not for the Nodes. This value means that HyperServer can open up to 20 monitor sessions.

Max sessions for Nodes is defined in the related CFG file.

I see. So, since my UniServerModule.ServerLimits.MaxSessions is 250 and I have max_nodes in Hyperserver.cfg set at 8, I should have a theoretical limit of a maximum active sessions at 250 x 8 = 2,000 or 250 / 8 = 31.25?
