You can add TextBoxWatermarkExtender alogn with Textbox on page.

It looks like OP needs exactly this, not "real watermarks". Will you post it as an answer? I would up-voted it as the correct answer.

Yes, we can. How about your? :-)
This is not really a question. Help with what, exactly? What did you try? You code sample is not related to watermarks.

can we use TextBoxWatermarkExtender for dynamically created texboxes??

Sergey Alexandrovich Kryukov 29-May-13 2:32am

I guess the first comment provides you with a solution. Did you check it out?

I have added one answer to do it in javaScript, no need to use Ajax.
Please take a look.

Sergey Alexandrovich Kryukov 29-May-13 8:47am

Actually, I do understand that Ajax would not be needed, as the required effect only modifies presentation. Where is it used?

Yes, we can use this Ajax for this scenario.

But I just suggested the normal one using javaScript, thinking if OP has ever used Ajax in his application or not. Else he will face problems again.

Sergey Alexandrovich Kryukov 29-May-13 9:00am

I understand. I think what you suggested is better. I just don't know what solution with Ajax are you comparing it to.

I am referring to the link provided by vijay__p in the first link.
-> First we need to add Ajax Reference to project. Again add reference to page.
-> Then add that TextBoxWatermark extender dynamically from c#.

So, the solution I provided is much more easier than that.

Sergey Alexandrovich Kryukov 29-May-13 11:13am

Aha, I see now. I agree. I did not pay attention for how it's implemented, only saw the demo.
Thank you,

You need to add some attribute to the TextBox at runtime so that it can be WaterMarked.

Refer - Asp.net create watermark text for textbox in javascript[^], which the simplest method to do the WaterMarking on TextBox. But the TextBox is not dynamic.

ASP.NET

<asp:Textbox ID="txtUserName" 
             runat="server" 
             Text="Enter Username Here" 
             ForeColor="Gray" 
             onblur="WaterMark(this, event);" 
             onfocus="WaterMark(this, event);" />

So, here there are different attributes defined to do this task.

As you have dynamic TextBox, so you have to just add those dynamically from code behind.
Use the javaScript functions defined there and add the following codes to add attributes dynamically.

So, you need to 3 steps.

Add Text to TextBoxes.
Add Gray Color.
Add the Attributes.

C#

TextBox TxtATUserID = new TextBox();
TextBox TxtATPassword = new TextBox();

// Add text to TextBoxes.
TxtATUserID.Text = "User ID";
TxtATPassword.Text = "Password";

// Add Gray color.
TxtATUserID.ForeColor = System.Drawing.Color.Gray;
TxtATPassword.ForeColor = System.Drawing.Color.Gray;

// Add the Attributes.
TxtATUserID.Attributes.Add("onblur", "javascript:WaterMark(this, event);");
TxtATUserID.Attributes.Add("onfocus", "javascript:WaterMark(this, event);");
TxtATPassword.Attributes.Add("onblur", "javascript:WaterMark(this, event);");
TxtATPassword.Attributes.Add("onfocus", "javascript:WaterMark(this, event);");

TxtATUserID.ID = "TxtUserName" + ViewState["textboxcount"].ToString();
TxtATPassword.ID = "TxtPassword" + ViewState["textboxcount"].ToString();

TxtATPassword.TextMode = TextBoxMode.Password;
this.PlaceHolder1.Controls.Add(TxtATUserID);
this.PlaceHolder1.Controls.Add(TxtATPassword);

NOTE
Don't forget to add that javaScript function WaterMark() in your page.
