    DBGrid - Next & Previous page

    in General

    Posted

    Dear sir,

    I am evaluating unigui and i haven't found a way to make unimdbgrid move to next and previous page using a form button. This is important for our company to move on buying unigui . Even if this can't be done UNIGUI is a unique component for delphi developers.

    in Feature Requests

    Posted

    I found the answer .... Add the code bellow to CalendarPanel.ExtEvents.eventsrendered

    function eventsrendered(sender, eOpts)
{           var curView = sender;
            var evtElements = Ext.select('.ext-cal-evt', true);
            if (evtElements)
            {
                //Loop through all elements
                Ext.each(evtElements.elements, function(eachEl) {
                    //Get EventId from from elment
                    var evtId = curView.getEventIdFromEl(eachEl);
                    var rec = sender.getEventRecord(evtId);
                    if (!Ext.isEmpty(rec))
                    if (!Ext.isEmpty(evtId)){
                        var pop_content =  "<div id='popup-data'><p><b>Details: </b>" +rec.data.Notes.replace(/\n/g, "<br />")+"</p></div>";
                          new Ext.ToolTip({
                           target: eachEl
                           ,title: rec.data.Title
                           ,dismissDelay: 2000 // auto hide after 2 seconds
                           ,anchor: 'top'
                           ,anchorOffset: 85
                           ,trackMouse: true
                           ,html: pop_content
                          });  

           
                    }
                }, this);
            }

    UniCalendar Panel Event Hint

    in Feature Requests

    Posted

    I am using the code bellow to display hints when the mouse is over an event... The problem i'm having is that the hint is displayed the second time the mouse goes over the event. I searched the net and i found that the problem is because i create the tooltip inside the eventover .... Is there a workaround???

    function eventover(sender, rec, el, eOpts)
{
  var pop_content =  "<div id='popup-data'><p><b>Details: </b>" +rec.data.Notes.replace(/\n/g, "<br />")+"</p></div>";
  new Ext.ToolTip({
   target: el
   ,title: rec.data.Title
   ,dismissDelay: 2000 // auto hide after 2 seconds
   ,anchor: 'top'
   ,anchorOffset: 85
   ,trackMouse: true
   ,renderTo: Ext.getBody()
   ,html: pop_content
   }).show;
}

    Mobile browser screen size

    in Mobile Browsers

    Posted

    You can use

    ClientEvents->ExtEvents->OnResize

    function window.OnResize(sender, width, height)
{
   ajaxRequest(sender, 'screensize', ['width='+width,'height='+height] );
}

    And do what ever you want in the form implementing OnAjaxEvent of the form

    procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TStrings);
begin
  if(EventName='screensize') Then Caption:=Params.Values['width'];
End;

    UniDBLookupCombobox Editable and Empty Value And value not in list

    in Components and Code Samples

    Posted

    I found the solution for the database problem and its working like a charm.. :)

    Add the code of the previous post and then just add a dummy value to your query

    eg. : SELECT -1 as id,'' as descr  from dummy union all select id, descr FROM books ;

    You can now search the unidblookupcombobox list values and CLEAR the data, also if value not in list lookup will get previous value ...

    UniDBLookupCombobox Editable and Empty Value And value not in list

    in Components and Code Samples

    Posted

    For those having problems allowing empty value or the selection of only items in list with incremental search in an editable DBLookupComboBox... (i was one too :rolleyes: ) Add to the DBLookupCombobox -> ClientEvents -> ExtEvents -> OnAfterrender 

    function OnAfterrender(sender){ 
sender.allowBlank=true; 
sender.editable = true;//This allows you to edit the DBLookupCombobox 
sender.forceSelection=true;//This line allows only item in list to be selected
sender.beforeBlur= function(){ 
var value = this.getRawValue(); 
if(value == ''){
this.lastSelection = []; 
}
 this.doQueryTask.cancel(); 
this.assertValue(); 
}
}

    I face a problem on setting null value to the coresponding field at server because the above trick does not set null value to field. I tryed and an ajax request to achieve the update.. but it keeps the last keyfieldvalue of the field.. if anyone can help :(
