There may be more than one container on your page, such as N panel, and a panel with n textbox;

So first you need to get the index container:

foreach (System.Web.UI.Control control in controls)//calendar passes through each control in the container.

Then iterate through all the controls in each container

for (int i = 0; i < control. Controls.Count; i++)//This is the control that traverses all the containers;

Then, in determining whether it is a TextBox control:

if (control. Controls[i] is System.Web.UI.WebControls.TextBox)

Empty multiple textbox at once:

foreach (System.Web.UI.Control Control in Controls)

{

for (int i = 0; i < control. Controls.Count; i++)

{

if (control. Controls[i] is System.Web.UI.WebControls.TextBox)

{

System.Web.UI.WebControls.TextBox TB = (System.Web.UI.WebControls.TextBox) control. Controls[i];

Tb. Text = "";

}

}

}
