I'm new to react and i've written my query for this message list for "How to change color of the left aligned text?" and i've got the solution but now my query is - If i get a new message then it should display down the new message in the conversation but instead of showing the updated message, It is scrolling upwards and showing older message first.
Can anyone help me in this? Thanks in advance for helping.
I will recommend this library react-scroll-to-bottom. You can see the working demo here.

And want to clear the message after posting but when i use this link solution "How to clear the input after posting the data through fetch and making the code execute successful" sometimes the message is getting disappear and sometimes message is not getting posted.

You need to use the value from the state inside input to be able to clear it:
<input
className="sendMessage"
onChange={this.handleChange}
name="body"
value={this.state.body} // Add input value
/>
I am fairly new to react native and have been attempting to build a very simple registration app.
Currently I have 2 screens running, the first landingscreen.js includes a button to prompt the first registration screen.
This screen works fine but its title shows as blank. (I am using react-navigator)
Below is the screen and you can find the corresponding code here.
On clicking the register here button the next screen is prompted which should show two fields an email and password field with the title "Let's create an account". As you can see below , all that works is the next button but I have no compilation errors. The code pertaining to this screen may be accessed here.
Any help or way pointing would be more than appreciated.
Thanks,
J.
Change navigation(you have written navigtion) spelling
static navigationOptions= {
title: "Let's make an account",
}
The headers not being seen was solved as #Paras Watts noted by fixing a spelling mistake.
To get the fields to show I then put the jsx pertaining to the form in the same render as the navigation also changing any tags to view to stick to the format of jsx.
I have no idea what is wrong in the simple code i have written to select a value from the dropdown. I have been watching other tutorials and code samples and i dont find any mistake in my code. Could someone please help me? I have tried running my code in Chrome as well as Mozilla(on two different OS) but still the issue exists.I am posting attachment of the html as well as selenium code.
Also, i am sure the problem is not because i have used wait because even if i comment that line or use it after loading the web page, the issue is there.
HTML
Selenium
Why don't you try clicking on the dropdown and then selecting the value.
tp.click();
and then
Select dropdown = new Select(tp);
dropdown.selectByValue("2");
new Select (driver.findElement(By.id("custtitle"))).selectByValue("2");
OR
new Select(driver.findElement(By.id("custtitle"))).selectByVisibleText("Mrs.");
I have a ultraComboEditor1 box that shows all the values linked to a data source. When I select item from the comboEditor and click on a button this item then appears in a grid. However I'm struggling to clear the item from the comboEditor. This is needed so it makes data entry easier for the user.
I have looked online and the only information I can find is for C# where this would be used:
ultraComboEditor1.RowSource = "".
or
ultraComboEditor1.item.Clear().
or
ultraComboEditor1.SelectedIndex = -1.
these all work but in 4GL when trying any of these I get eh error message "Unknown Table name UltraComboEditor1" as only tables can be followed by a .
can anyone help me figure out how to do this in 4GL or provide with some information that may help?
Thank
Matt
You need to use ":" instead of "." to translate your c# examples into 4GL -
ultraComboEditor:Item:Clear()
etc
I have used: ultraComboEditor1:text = "". to clear the combo Editor on the button click event.
Thanks Anyway.
