Hi,
I am trying to get TextBox. Whenever I click on the button I should get a TextBox. Here is my code. But I am getting only one TextBox.

private void button1_Click_1(object sender, EventArgs e)
{
    txtRun = new TextBox();
    txtRun.Name = "txtDynamic";
    txtRun.Location = new System.Drawing.Point(20, 18);
    txtRun.Size = new System.Drawing.Size(200, 25);
    // Add the textbox control to the form's control collection
    this.Controls.Add(txtRun);
}

Any help would be appreciated.

Solution 1

Your text boxes are all in the same place, and all have the same name. You're either getting many text boxes that are all in the same place, so they cover each other, or because the name is the same, your new one is replacing your old one.

Hi,

what should i do to avoid that....

You need to somehow change the properties that Christian indicated were conflicting. ie you need to dynamically change the location.

You could use member variables initialised to some value eg. x = 10, y = 10 then:

x += 10;
y += 10;
System.Drawing.Point(x, y);

I would also append the name with a counted variable...txtDynamic1,txtDynamic2 etc

Hi,
I have added the same ..but iam getting second text box in the middle of the first textbox..i have to get one after the another in next line with some space..

Any help would be appreciated.

neetika you need to do some maths, the reason you are getting that is because 10 is just a random number i pulled out of my... hat.

A quick fix: Instead of using the values 10 that I used, if you want to put a textbox below another one, add the height of the textbox + 2 pixesl so you get y = textbox.Height + 2; and if you wanna put it next to the other one use x = textBox.Width + 2;

You need to remember that the location property is taken with respect to the top left hand corner of the form (0,0).

;) ;) ;) ;) ;) ;) you should change your textboxs location after cliking button . all location should be diffrent.:cool::cool::cool::cool:
like this

string x=40;
private void button1_Click_1(object sender, EventArgs e)        {            
           txtRun = new TextBox();            
           txtRun.Name = "txtDynamic";            
           txtRun.Location = new System.Drawing.Point(x+20,18);
           x+=10;
           txtRun.Size = new System.Drawing.Size(200, 25);            
           this.Controls.Add(txtRun);        
}

Hi neetika2010,

Just set 'y' value in Location Point.

C#

//Assign this Value in Global
int x=100;
int y=25;

// In Your Button Event
private void button1_Click_1(object sender, EventArgs e)        {
           txtRun = new TextBox();
           txtRun.Name = "txtDynamic";
           txtRun.Location = new System.Drawing.Point(x,y);           
           txtRun.Size = new System.Drawing.Size(200,25);
           y=y+25;  
           this.Controls.Add(txtRun);
}

If you need a large space in between a Textbox just add a value in y.
ex: y=y+35;

In my Suggestion using UserControl you can create any control one after another.

Thanks :)

Toni is the grid static though or can you keep adding rows and columns?
