PowerApps visibility of the next button based on the rating - sharepoint

So I am trying to make the Next button only visible when the user chooses a rating, but every time I apply one of these codes:
If(Rating2.Value = 0; DisplayMode.Edit; Disabled) or If(Form9_3.Valid; DisplayMode.Edit; Disabled)
The Next button stays grayed out... Any ideas on how to do this better?

Your function right now likely is on the button's Display Mode property. You want to put your function on the button's Visible property.
If(Rating2.Value = 0; false; true)
Make sure the default value of your Rating component is set to zero.

compute Visible property for a button, based upon length of a textarea field

I would like to calculate the visibility of a button based upon the content of a text area field (multi line edit box). it should contain at least some text.
I could use the onkeypress event (server) and perform a partial refresh on the button BUT I notice that the partial refresh spinner appears then when users are writing in the field. I would like to avoid this.
What options do I have?
You would be best off writing a client side script for that event. This script should show the button when there are more than 200 characters in the textarea. You will need to set the style visibility to hidden for the button initially. If the form can be edited multiple times, you will need to write this as a function and call it on page load as well as in the keypress event.
If you can use the keyup event instead of keypress, this may be better.
var textareaID = '#{id:textareaID}';
var buttonID = '#{id:buttonID}';
var textareaValue = document.getElementById(textareaID).value;
var visibility;
if (textareaValue.length > 200) {
visibility = 'visible';
}
else
{
visibility = 'hidden';
}
document.getElementById(buttonID).style.visibility=visibility;

Disabling button in a specific row of a C1TrueDBGrid

I am using c1truedbgrid. I have columns added in the grid with one column having button which is displayed is every row. I need to disable the button in a particular row depending on some business logic. How this can be done?
I am not sure why there aren't any answer.
Its fairly simple. Lets say I want to disable the buttons from those rows where ID is even.
for(int i = 0; i< c1truedbgridobject.Splits[0].Rows.Count; i++)
{
if(Convert.ToInt32(c1truedbgridobject[i,1].ToString())%2 == 0)
{
//Disable here
}
}
However the disable part is dependent on how you are adding button to a cell. Since add button is referenced to whole column and not to a particular cell.
Anyhow using a OwnerDrawCell is also an option.
EDIT:
This seems as a limitation of C1TrueDBGrid. You may use C1FlexGrid as an alternative.
You need to make property of that column as "locked=True" as Below example when you initializing grid.
C1TrueDbGridName.Splits(0).DisplayColumns("YourColumnNameHavingButton").Locked = True
it will make your row not to be editable

onchange event in XPages

I have two edit boxes in an XPage and one label.
Leave Start Date : EDIT BOX
Leave End Date : EDIT Box
Holidays Taken : label
I want to calulate the diffence in dates and get it computed in the label using the following code in onChange event of second(Leave End Date) edit box but on chaging the value of the edit box it clears the two field and nothing gets computed:
var leaveStartDate = document1.getValue("fld_Leave_Start_Date1");
var leaveEndDate = document1.getValue("fld_Leave_End_Date1");
var difference = null;
try{
var nDateStart = session.createDateTime( leaveStartDate );
var nDateEnd = session.createDateTime( leaveEndDate );
difference = nDateEnd.timeDifference(nDateStart);
difference = (Math.floor(difference/86400)) + 1;
}catch(e)
{
return e
}
document1.setValue("fld_NoOfDays",difference);
I tried getComponent("fld_Leave_Start_Date1").getSubmittedValue(), but didn't work either.
Can someone please help.
Thanks a lot in advance!
If the edit boxes are getting cleared, it sounds like you've set the event to do a full refresh instead of a partial refresh.
The other possible cause of clearing fields is if you're using Partial Execution Mode (execMode="Partial" in the source pane for the eventHandler) but have specified a execId that does not include the two edit boxes. (Partial Execution by default runs on the current component, so you should not lose the values of that Edit Box.) But I don't think that's the case.

C# TableLayoutPanel replace control?

I was wondering if it was possible to replace one control in a TableLayoutPanel with another at runtime. I have a combo box and a button which are dynamically added to the TableLayoutPanel at runtime, and when the user selects an item in the combo box and hits the button, I'd like to replace the combobox with a label containing the text of the selected combo box item.
Basically, if I could simply remove the control and insert another at it's index, that would work for me. However I don't see an option like "splice" or "insert" on the Controls collection of the TableLayoutPanel, and I was wondering if there was a simple way to insert a control at a specific index. Thanks in advance.
Fixed this by populating a panel with the two controls I wanted to swap and putting that into the TableLayoutPanel. Then I set their visibility according to which I wanted to see at what time.
This is what I've been able to come up with for what I needed. It gets the position of the ComboBox and makes a new label using the selected value.
// Replaces a drop down menu with a label of the same value
private void lockDropMenu(ComboBox dropControl)
{
TableLayoutPanelCellPosition pos = myTable.GetCellPosition(dropControl);
Label lblValue = new Label();
myTable.Controls.Remove(dropControl);
if (dropControl.SelectedItem != null)
{
lblValue.Text = dropControl.SelectedItem.ToString();
lblValue.Font = lblValue.Font = dropControl.Font;
// Just my preferred formatting
lblValue.AutoSize = true;
lblValue.Dock = System.Windows.Forms.DockStyle.Fill;
lblValue.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
myTable.Controls.Add(lblValue, pos.Column, pos.Row);
}
}

Set value for YUI Menu Button

I'm trying to set the assigned value to a YUI Menu Button in order to use values from previous operations.
Something like remembering previous choices.
For label I already know that I can change it with:
button.set("label", "my label")
unfortunatelly I cannot change the value using: button.set("value", "my value")
Any ideia on how can I do this?
Other way would be to force a selection, but I have no ideia on how to do that.
Thanks
just found out that you can use:
var menu = button.getMenu();
var item = menu.getItem(index);
button.set("selectedMenuItem", item);
all that is left for me now is finding the needed index
