Dynamic text box control creation and text_changed event code

Question

Hi all,

Here I am creating dynamic text box control and i want to fire text_changed event to this created text box. But i have query on this event,

Example i need to display HELLO when text changed so code

response.write("HELLO");

Now my query is the above line where i need to write or how i need to call the function(set of code) to fire when text_changed event fired, why because we are creating and firing this event dynamically.

Please help me..

Call the same textchanged event for all textboxs based on some id or value from database so that you can check till the tb1 = sum of others.

Hi Madhu, thank you once again. let me explain my situation. I getting a value into text box(tb1) from data base and then i am checking this value with another text box(tb2) value. if tb1!=tb2 then { create dynamic text box(tb3) and access the input value } and now compare the value with tb1 like below if (tb1 != tb2+tb3) { create dynamic text box(tb4) and access the input value } like this sum of all other text box values = tb1 then stop creating dynamic text boxes and perform some logic in button click. Please help me on this.

If the method you are calling in textchanged event is different for each text box then I am afraid you have to write for each textbox.

Hi Madhu. thank you for you reply. If i have creating more than one text box control and i am checking some constraint. I am creating text box controls up to that constraint statisfies. so i don't know how many times text boxes creating so how to write the below event handler protected void TextBox_TextChanged(object sender, System.EventArgs e) { TextBox tb = (TextBox)sender; Response.Write("My code here"); } Please help if I creating more than one text box control.

After creating the dynamic textbox add the TextChanged event of the textbox and set autopostback to true. tb.TextChanged += this.TextBox_TextChanged; Then in textchanged event you write your code protected void TextBox_TextChanged(object sender, System.EventArgs e) { TextBox tb = (TextBox)sender; Response.Write("My code here"); }
