Setup IWGrid visibility in OnAsyncClick event - brsoft - 09-07-2019
Hi
Simple bug in IW15.1.4, but very annoying.
OnAsyncClick Event:
IWGrid1.visible: = not IWGrid1.visible;
... and the position of the Grid is moving!
(The position is correct for the OnClick event.)
Other components have no such error.
Error presentation:
http://95.140.46.153/gridvisibletest
Can you help me with this?
Best regards
brsoft
Code:
type
TIWForm1 = class(TIWAppForm)
IWGrid1: TIWGrid;
IWButton1: TIWButton;
IWButton2: TIWButton;
procedure IWButton1AsyncClick(Sender: TObject; EventParams: TStringList);
procedure IWButton2Click(Sender: TObject);
public
end;
implementation
{$R *.dfm}
procedure TIWForm1.IWButton1AsyncClick(Sender: TObject; EventParams: TStringList);
begin
IWGrid1.Visible:=not IWGrid1.Visible;
end;
procedure TIWForm1.IWButton2Click(Sender: TObject);
begin
IWGrid1.Visible:=not IWGrid1.Visible;

Hi
Unfortunately, we had to go back to IW15.0.24.
What will you do with the error?
1. "It's Not a Bug, It's a Feature." This is how it will work in the future.
2. The next version is expected to fix the problem.
Hope I get an answer ...
regards

Please update to IW 15.1.5 which fixes this and other rendering issues after an Async event.

Hi Alexandre,
Thank you for your help, but I have a new question.
I don't understand why the HTML code changed:
IW15.1.4:
Code:
<div CLASS="tblpanel tbllist" ID="MENUGRID" style="overflow-x: auto; overflow-y: auto; "><table cellpadding="0" cellspacing="0" id="TBLMENUGRID" style="">
<thead></thead>
<tbody>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu1</td></tr>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu2</td></tr>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu3</td></tr>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu4</td></tr></tbody></table></div>IW15.1.5:
Code:
<div CLASS="tblpanel tbllist" ID="MENUGRID" style="overflow-x: auto; overflow-y: auto; "><div style=""><table cellpadding="0" cellspacing="0" id="TBLMENUGRID">
<thead></thead>
<tbody>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu1</td></tr>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu2</td></tr>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu3</td></tr>
<tr><td class="okmenuitem" style="white-space: nowrap; height: 24px; "> Menu4</td></tr></tbody></table><script data-type="iw" nonce="ea3sd5wF7k7Ggc1Al/7JT/tOxgs" type="text/javascript">
var tbl = IW.$("TBLMENUGRID");
if (tbl) {
tbl.style.cssText += tbl.style.cssText;
}
</script></div></div>We had to modify some javascript slightly, but it was not significant.
TBLIWGRID's parentNode is not an IWGRID but an anonymous div.
I tried to make a demo, but I couldn't make an example. In our recompiled applications, however, every grid has this HTML code.
Which setting does this?
best regards

IWGrids sometimes would have this inner div and sometimes not depending on UseFrame property which creates other issues. The code was simplified and the internal DIV is always used
