Dynamic TextBox TextChanged is not firing in UpdatePanel

My dynamic textboxes TextChanged event is working properly without using UpdatePanel, but when i use UpdatePanel it stops working. it works only when Button is clicked and when the LinkButton is clicked.
How can i set TextChanged event of dynamic textboxes as trigger for the UpdatePanel. I hope this is clear for you.
This is my aspx
<form id="form1" runat="server" enctype="multipart/form-data">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Name :"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
<asp:Label ID="Label2" runat="server" Text="Age :"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<br />
<asp:Label ID="Label3" runat="server" Text="Phones :"></asp:Label>
<br />
<asp:Panel ID="pnlTextBox" runat="server">
</asp:Panel>
<asp:LinkButton ID="btnAddTxt" runat="server" OnClick="btnAddTxt_Click">Add TextBox</asp:LinkButton>
<br />
<br />
<asp:Button ID="Button1" runat="server" Text="save" OnClick="Button1_Click" />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
</form>
and this is code behind
protected void Page_PreInit(object sender, EventArgs e)
{
//Recreate Controls
RecreateControls("txtDynamic", "TextBox");
}

{
int cnt = FindOccurence("txtDynamic");

{

{
if (ctrls[i].Contains(ctrlPrefix + "-" + k.ToString()) && !ctrls[i].Contains("EVENTTARGET"))
{
string ctrlID = ctrls[i].Split('=')[0];
if (ctrlType == "TextBox")
{
CreateTextBox(ctrlID);
}
break;
}
}
}
}
}
private void CreateTextBox(string ID)
{
TextBox txt = new TextBox();
txt.ID = ID;
txt.AutoPostBack = true;
txt.TextChanged += new EventHandler(OnTextChanged);
pnlTextBox.Controls.Add(txt);
Literal lt = new Literal();
lt.Text = "<br /><br />";
pnlTextBox.Controls.Add(lt);
}
protected void OnTextChanged(object sender, EventArgs e)
{
TextBox txt = (TextBox)sender;
string ID = txt.ID;
//Place the functionality here
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('" + ID + " fired OnTextChanged event')", true);
}
protected void Button1_Click(object sender, EventArgs e)
{
TextBox txtDynamic1 = (TextBox)this.form1.FindControl("txtDynamic-1");
TextBox txtDynamic2 = (TextBox)this.form1.FindControl("txtDynamic-2");
Response.Write(txtDynamic1.Text + " & " + txtDynamic2.Text);
}

You can refer to this URL and add the postback trigger from the code behind instead of the aspx. https://forums.asp.net/t/1124967.aspx?Adding+a+Trigger+to+an+UpdatePanel+in+code+behind

DropdownList SelectedIndexChanged inside Repeater fires up while under UpdatePanel and click another Dropdownlist outside repeater

I have a 2 Dropdownlist outside a repeater (1st ddl will trigger and refresh the content of the repeater, 2nd ddl refresh its list after an item inside the repeater were executed) and a dropdownlist control inside the repeater.i don't have a problem with the 1st dropdownlist but the 2nd dropdownlist when triggered via selectedindexchanged, it also fires up the selectedindexchanged of the dropdownlist inside the repeater. I put up an UpdatePanel on the repeater and on the 2nd dropdownlist but still the error occurs.
How can i trace the step by step execution and also why the selectedindexchanged handler fires up?
Here is the code snippet:

you can do as below
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
AddItems();
}
}
private void AddItems()
{
if (!string.IsNullOrEmpty(TextBox1.Text))
{

for (int j = 1; j <= a; j++)
{
Guid IDUnik = new Guid();
artikulli = new DropDownList();
cmimi = new TextBox();
tregoCmimi = new Label();
sasia = new TextBox();
cmimiGjithsej = new Label();
artikulli.ID = j.ToString(IDUnik.ToString("N").Substring(31));
artikulli.AutoPostBack = true;
cmimi.ID = j.ToString(IDUnik.ToString("D").Substring(30));
tregoCmimi.ID = j.ToString(IDUnik.ToString("P"));
sasia.ID = j.ToString(j.ToString(IDUnik.ToString("X")));
cmimiGjithsej.ID = j.ToString(j.ToString(IDUnik.ToString("B"))); ;
PlaceHolder1.Controls.Add(artikulli);
PlaceHolder2.Controls.Add(cmimi);
PlaceHolder3.Controls.Add(tregoCmimi);
PlaceHolder4.Controls.Add(sasia);
PlaceHolder5.Controls.Add(cmimiGjithsej);
artikulli.Items.Insert(0, new ListItem("<Select Subject>", "0"));
artikulli.Items.Insert(1, new ListItem("<Select Subject>", "1"));
}
}
}
you don't need OnTextChanged="TextBox1_TextChanged" in your textbox

protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
Populate();
}
}
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
Populate();
}
void Populate()
{
PlaceHolder1.Controls.Clear();
PlaceHolder2.Controls.Clear();
PlaceHolder3.Controls.Clear();
PlaceHolder4.Controls.Clear();
PlaceHolder5.Controls.Clear();
if (!string.IsNullOrEmpty(TextBox1.Text))
{
int a = int.Parse(TextBox1.Text);
for (int j = 1; j <= a; j++)
{
Guid IDUnik = new Guid();
artikulli = new DropDownList();
cmimi = new TextBox();
tregoCmimi = new Label();
sasia = new TextBox();
cmimiGjithsej = new Label();
artikulli.ID = j.ToString(IDUnik.ToString("N").Substring(31));
artikulli.AutoPostBack = true;

It looks like you probably just need to call that JavaScript function that initializes your "Background Stretcher" on each UpdatePanel update (rather than just when the DOM loads). Changing that function to this should do the trick:
function pageLoad() {
$('BODY').bgStretcher({
images: ['images/slide-1.jpg'],
imageWidth: 1600,
imageHeight: 964,
resizeProportionally: true
});
}
Notice that I used function pageLoad() { (should be called on each postback, including AJAX partial postbacks) rather than $(function () { (only called once, when the DOM loads).

Hide/show table in gridview on button click event

I have project on recruitment.In this project, at one form I have a grid view which contains details of all vacancies. Along with this there is button. When user clicks on this button, available interview schedule for that particular vacancy will be visible in another grid below that row. What I did is I have placed grid view inside table and table is initially invisible. When user clicks on the image button, at that time I tried to find table from the grid view but it can not be found.
Here is the code of my .aspx page

Please show me my problem...

You have provided too much code, that can't be read easily. You have to narrow it down to a specific point.
Let me try to help you on your specific problem.
If you set the control visible=false it will not render at client side and you can't make that control visible later on in client side. Have a look at this similar thread to get an idea how to proceed: Want to make the visibility true from client side of the control which made invisible from server side
