Unable to place cursor after adding textbox control in windows form and adding form to panel control

Question

Unable to place cursor after adding textbox control in windows form and adding form to panel control

Hi,

Below are the steps to reproduce an issue.

Created Form1.cs
Added split container to Form1.cs
Added panel to SplitContainer.Panel2
Created Form2.cs
Added three textbox controls to Form2.cs
Added below lines of code

Form2 frm2 = new Form2();
frm2.TopMost = true;
frm2.TopLevel = false;
frm2.BringToFront();
frm2.Parent = panel1;
frm2.Show();

Initially cursor is at 0th position and when trying to place cursor in the middle using mouse, full text is getting selected. I am unable to place cursor on mouse click at specified position .

Hi @Patil, Narayana Reddy (Cognizant) ,
>>Initially cursor is at 0th position and when trying to place cursor in the middle using mouse, full text is getting selected.
I followed your steps and got the following situation.

Here is my code example:

private void Form1_Load(object sender, EventArgs e) { splitContainer1.Panel1.BackColor = Color.Green; splitContainer1.Panel2.BackColor = Color.Red; Form2 frm2 = new Form2(); frm2.TopMost = true; frm2.TopLevel = false; frm2.BringToFront(); frm2.Parent = panel1; frm2.Show(); }

I can't reproduce your problem, please point out the problem in my steps, or provide more detailed information to reproduce the situation.

Maybe such unusual scenario is not designed and is not supported. Instead of Form2 you can define a UserControl. Then it can be inserted to your panel or to separate forms.

Hi @Patil, Narayana Reddy (Cognizant) ,
Since form2 is not a top-level window, the Windows window manager cannot activate the window. So set borderless (remove the subtitle bar in the form) to convert the form into a control that is indistinguishable from the user control, so that the textBox can work normally.

Answer 1

Hi PatilNarayanaReddyCognizant-3509,
I reproduced the problem through your description. This happens because you are displaying a form with a title bar.
You need to remove the title bar from the form via following code:

frm2.FormBorderStyle = FormBorderStyle.None;

More details you can refer to this thread.
