Hi  Khanh, 

 

Thank you for contacting Syncfusion Support. 

 

Query: i need all text in the textbox will be selected every time the textbox is clicked / instead of clicking and ctrl + Alt. How can this be achieved? (If focused, skip this) 

 

From your update, we could understand that you want to select all text on clicking the textbox and you want to deselect the text, if the textbox get focused. If this your requirement, then you can achieve using SelectAll method on click event of TextBoxExt and we have unselected the text using the following code: 

 

Code: 

 

 

// Select all text at click event 

        private void TextBoxExt1_Click(object sender, EventArgs e) 

        { 

            this.textBoxExt1.SelectAll(); 

        } 

 

 

//unselect the text on focus 

        private void TextBoxExt1_GotFocus(object sender, EventArgs e) 

        { 

            this.textBoxExt1.Select(this.textBoxExt1.Text.Length, 0); 

        }

Please try this solution and let us know if it is helpful.

Hi Vijayalakshmi,

I'm working with a multi-line textbox,

Your code works partly for me,

i'm looking for the following codes:

if (textbox.focus) return; // if focusing then nothing happens

textbox.selectall; // happens for each first focus

Your code works with every click, I want after the first click, it has to ignore because it's focused, but it's still selectall.

Hi Khanh, 

Thanks for your patience. 

We have checked your query “Need to ingnore the focus after the first click”. You can achieve this by unhook the click event of TextBoxExt control. Please refer the below code snippet and sample below, 

 

Code Example 

 

 

this.textBoxExt1.GotFocus += TextBoxExt1_GotFocus; 

this.textBoxExt1.Click += TextBoxExt1_Click; 

 

private void TextBoxExt1_Click(object sender, EventArgs e) 

{ 

    this.textBoxExt1.SelectAll(); 

    this.textBoxExt1.Click -= TextBoxExt1_Click; 

} 

private void TextBoxExt1_GotFocus(object sender, EventArgs e) 

{ 

    this.textBoxExt1.Select(this.textBoxExt1.Text.Length, 0); 

}

Hi Backia Raj ,

based on your code, now they are working,

Is there a function that checks whether the textbox focusing in addition to using events, and a global variable for this?

[Backia Raj Kanagaraj]

Hi Khanh, 

 

Thanks for your update. 

 

You can achieve your requirement “Need to ingnore the focus after the first click” by using global variables. We have set bool variable is false after the first click. So that after the first click the text is not selected. Please refer the below code example and sample. 

 

Code snippet: 

 

private void TextBoxExt1_GotFocus(object sender, EventArgs e) 

{ 

   focused = true; 

} 

 

bool focused = false; 

private void TextBoxExt1_Click(object sender, EventArgs e) 

{ 

   if (focused) 

   { 

      this.textBoxExt1.SelectAll(); 

      focused = false; 

   } 

}
