There is form with text element that should receive focus every time form shown.
In .NET CF Form has no OnShow(n) event
I try to use workaround:
MyForm_GotFocus() // or MyForm_Activated
{
txtTextControl.Text = string.Empty;
txtTextControl.Focus()
}
txtTextControl_GotFocus()
{
txtTextControl.SelectAll()
}
Code for getting form instance:
public static MyForm GetForm
{
get
{
if (s_inst == null || s_inst.IsDisposed)
{
s_inst = new MyForm();
}
return s_inst;
}
}
public static void ShowForm()
{
var frm = GetForm;
frm.Show();
}
1) First time ShowForm (Form instance has been created): txtTextControl emptied and got focus, txtTextControl_GotFocus event raised
2) Second time ShowForm : OK too
3) Third time ShowForm : txtTextControl emptied, but does not get focus
Is there bug or feature? Is there workaround? Show I rewrite ShowForm? Is OpenNETCF.IOC.UI is better solution (50 forms in project)?
I had that same question once.
Set the TabIndex for the control to 0.

I have simple code:
ComboBox<String> combo=new ComboBox<>("Combo");
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setItems("11","22");
combo.setValue("22");
}
});
When I first time click button i have items "11" and "22" present in combobox and value "22" is selected.
Second click makes value cleared but items "11" and "22" are still present.
In case I select "11" or leave "22" selected in combobox and click button - value clears.
It seems that setValue() only works when combobox is empty but following code do not helps as well:
combo.setValue(null);
combo.clear();
combo.setItems("11","22");
combo.setValue(null);
combo.clear();
combo.setValue("22");
Following code sets value of ComboBox correctly, no matter if I select some value or clear it before click:
ComboBox<String> combo=new ComboBox<>("Combo");
combo.setItems("11","22");
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setValue("22");
}
});
But I have to set items of Combobox dynamically and the last solution do not suitable for me.
Vaadin version is 10.0.9.
Has anyone some suggestions or advices ?
PS.
Thanks !
I've tried following code:
combo.setItems(Collections.emptyList());
combo.setItems("11","22");
combo.setValue("22");
But it do not work as well.
This code works only if value in combo is empty, but if I input something in combo the code just clears value by .setItems() and further .setValue() do not work.
If value of combo is empty the code works well.
Your code works perfectly fine in a minimum project based on https://vaadin.com/start/latest/project-base (which uses Vaadin 12.0.7)
#Route("")
#PWA(name = "Project Base for Vaadin Flow", shortName = "Project Base")
public class MainView extends VerticalLayout {
public MainView() {
ComboBox<String> combo=new ComboBox<>("Combo");
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setItems("11","22");
combo.setValue("22");
}
});
add(combo,button);
}
}
Whatever value you set in the ComboBox via UI .. when the button is clicked, the selected value will switch to 22.
If that's an option for you, you could update to a newer Vaadin version and try it with that.
To better show what I meant in my comment, I'm writing it as an answer.
What I meant was to set an empty collection not in the clickListener but directly after initializing the ComboBox:
ComboBox<String> combo=new ComboBox<>("Combo");
combo.setItems(Collections.emptyList());
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setItems("11","22");
combo.setValue("22");
}
});
please try it out and let me know if that works
I'm trying to figure out a way to have an Excel-like behavior with the Grids on Ext JS.
Here is the sample grid I am working with. So far we can already naviguate through the cells with the arrows but only in edit mode.
However what I am trying to reach is the naviguation with the arrows, TAB and Enter keys outside of the edit mode, just like excel.
I tried to integrate this piece of code which overrides the Editor class, hoping that it would change the behavior of the cells but it doesn't change a thing.
I believe this is the most important part that overrides the Editor class and tries to include the keys input :
Ext.override(Ext.Editor, {
startEdit: function (el, value) {
var me = this,
field = me.field;
me.completeEdit();
me.boundEl = Ext.get(el);
value = Ext.isDefined(value) ? value : me.boundEl.dom.innerHTML;
if (!me.rendered) {
me.render(me.parentEl || document.body);
}
if (me.fireEvent('beforestartedit', me, me.boundEl, value) !== false) {
me.startValue = value;
me.show();
field.reset();
if (deleteGridCellValue) {
field.setValue('');
me.editing = true;
me.completeEdit();
deleteGridCellValue = false; // reset global variable
}
else {
if (newGridCellValue == '') {
// default behaviour of Ext.Editor (see source if needed)
field.setValue(value);
}
else {
// custom behaviour to handle an alphanumeric key press from non-edit mode
field.setRawValue(newGridCellValue);
newGridCellValue = ''; // reset global variable
if (field instanceof Ext.form.field.ComboBox) {
// force the combo box's filtered dropdown list to be displayed (some browsers need this)
field.doQueryTask.delay(field.queryDelay);
}
}
me.realign(true);
field.focus(false, 10);
if (field.autoSize) {
field.autoSize();
}
me.editing = true;
}
}
}
});
This is the first time that I am working on a project that is outside of Comp-Sci classes so any help would be very much appreciated. Thanks !
I have a Ribbon Form with a treelist on the left so i put a XtraUserControl to insert a DocumentManager in which i would like to add all my tabbed forms (like in Visual Studio).
How can i do this?
Thanks
I suggedt you start from the How to: Display Documents Using a Tabbed UI example. The main idea of this example is that you can add the DocumentManager onto the form and then handle a treelist item's Click to add all needed child forms as MDI-children - the DocumentManager will track all the changes automatically:
Form childForm = new Form();
childForm.MdiParent = this;
childForm.Show();
To read more about the another Document Manager concepts and features please refer to the corresponding documentation articles.
public void Viewchild(Form _form)
{
//Check Before Open
if (!IsFormActive(_form))
{
_form.MdiParent = this;
_form.Show();
}
}
//Check If a Form Is Opened Already
private bool IsFormActive(Form form)
{
bool IsOpened = false;
//If There Is More Than One Form Opened
if (MdiChildren.Count() > 0)
{
foreach (var item in MdiChildren)
{
if (form.Name == item.Name)
{
// Active This Form
xtraTabbedMdiManager1.Pages[item].MdiChild.Activate();
IsOpened = true;
}
}
}
return IsOpened;
}
open form in
Master.frmBranch fb = new Master.frmBranch();
fb.Name = "frmBranch";
I've Created a Model which have few custom validation. These custom validation I've annotated at property by below code
[CustomValidation(typeof(ItemmasterModel), "ValueTextMaxLenghtValidate")]
public decimal Valuetextmaxlength
{
get
{
return _Valuetextmaxlength;
}
set
{
ValidateProperty("Valuetextmaxlength",value);
_Valuetextmaxlength = value;
RaisePropertyChanged(() => Valuetextmaxlength);
}
}
public static ValidationResult ValueTextMaxLenghtValidate(object obj, ValidationContext context)
{
var itmmstr = (ItemmasterModel)context.ObjectInstance;
if (itmmstr.SelectedValuetypeDd != null)
{
string vtype = itmmstr.SelectedValuetypeDd.Key.ToString();
if (vtype.Equals("C"))
{
if (itmmstr.SelectedItemValueCodeTypesDd != null)
{
string vcode = itmmstr.SelectedItemValueCodeTypesDd.Key.ToString();
if (vcode.Equals("T"))
{
if (itmmstr.Valuetextmaxlength == null || itmmstr.Valuetextmaxlength == 0)
{
return new ValidationResult("Value Max Length is not Entered",
new List<string> { "Valuetextmaxlength" });
}
}
}
}
else if (vtype.Equals("T"))
{
if (itmmstr.Valuetextmaxlength == null || itmmstr.Valuetextmaxlength == 0)
{
return new ValidationResult("Value Max Length is not Entered",
new List<string> { "Valuetextmaxlength" });
}
}
}
return ValidationResult.Success;
}
Now this validation code depend on other property. scenerio When User select a value from dropdown it makes 1 checkbox selected automatically and User should enter the value in texbox also.
Issue:
Validation is working. checkbox is selected at first time then also it comes with error popup.
untill user doesn't make changes into this checkbox or texbox it is with error only. 1 time it says error even value has been entered .Next time it goes even user have not entered anything but during final full object validation is again comes with error.
Why this even ambiguity is happening. How to solve this.
Need more code let me know. I'll Post. Code is in Silverlight 5, MVVM Light
During my Custom validation I was using ValidateProperty("Valuetextmaxlength",value); before setting the value of property so It was giving me issue but the moment I set the value first and then Use my ValidateProperty("Valuetextmaxlength",value); everything worked smooth. Still I don't know the reason why but It worked for me.
I am using the WPF webbrowser and basically when I load an external url, i want to filter any pages that are loaded to make sure the url doesnt contain a swear or porn type word.
This is easy to do on page load, as I check the URL against my List badwords; I have also set up a Load Completed method which gets me the url of clicked words, however this isnt working properly :-
void webBrowser1_LoadCompleted(object sender, NavigationEventArgs e)
{
mshtml.IHTMLDocument2 doc = (mshtml.IHTMLDocument2)this.webBrowser1.Document;
foreach (IHTMLElement link in doc.links)
{
HTMLAnchorElement anchor = link as HTMLAnchorElement;
if (anchor != null)
{
HTMLAnchorEvents_Event handler = anchor as HTMLAnchorEvents_Event;
if (handler != null)
{
handler.onclick += new HTMLAnchorEvents_onclickEventHandler(delegate()
{
uxURLText.Text = anchor.href;
//if (HelperClass.isNotFile(anchor.href))
// {
if (basepage.nonSafeWords.WordsContainSwearWord(anchor.href))
{
System.Windows.MessageBox.Show(basepage.INTERNET_RESTRICTION_NOTICE);
}
else
{
System.Windows.MessageBox.Show("Word Ok");
}
return true;
});
}
}
}
}
I need to basically stop any bad content from loading in the window, either from link, button, or ajax if a bad link is clicked a popup needs to notify us. I also need to show the current url in the address bar
Please help many thanks
:)
Listen to the WebBrowser.Navigating Event (docs) and check the Uri in NavigatingCancelEventArgs. Then set e.Cancel = true if you to not want to allow the navigation.
But your valid Uri check is the more complex problem.
private void webBrowser1_Navigating(object sender, NavigatingCancelEventArgs e)
{
string currentURl= e.Uri.ToString();
_addrBox.Text = currentURl;
}
this was the solution in my case.
maybe itll help somebody
