Dynamically creates TextBox
Posted by :Zill-e-hussain bajwa
This article will show you how to create TextBoxes and DropDownList dynamically on ASP.NET page and then retrieve user input values from dynamically created controls.
I came across the requirement for a project that I was working on, my manager wanted me to accomplish a specific task by sending a message to a particular member of the group. He suggested I should design the screen, where the user can pick a members name from a DropDownList and type a message in a Textbox and submit that information to the system, but at the same time he wanted me to design the system that user would be able to send a multiple request to different members of the group. In this project I have design the screen where user types a message in Textbox and select the appropriate party name from the DropDownList and send that data to database for later process. The question arose how would I retain the ViewState after the PostBack and at the same time recreate the DropDownList control data and retain the TextBoxes control property text value for a multiple request?
Before I begin read my last article Dynamically create Textbox controls from which you will learn how to create TextBoxes control dynamically on ASP.NET page, and also read about how ASP.NET page life cycle works?
In this project I decided to manually assign a control id to the TextBoxes and DropDownList. After creating these controls I just added them to different placeholder controls.
// Add TextBoxes Control to Placeholder
private void CreateTextBoxes()
{
for (int counter = 0; counter <= NumberOfControls; counter++)
{
TextBox tb = new TextBox();
tb.Width = 250;
tb.Height = 60;
tb.TextMode = TextBoxMode.MultiLine;
tb.ID = "TextBoxID" + (counter + 1).ToString();
// add some dummy data to textboxes
tb.Text = "This is textbox " + counter + " da
