How to keep the textbox inside of a cell from gridview, in a postback

Question

My problem is the following, when you load the page for the first time you see the textbox inside the cell with the red background, but when there is a postback the textbox inside the cell is lost.

load method fill my gridview.

the idea is when the column color is red, i need to create a textbox and put the background of the textbox red;

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                Load();
            }
           

        }

 protected void GvCriticidad_RowDataBound(object sender, GridViewRowEventArgs e)
 {
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
      if (e.Row.Cells[2].Text == "RED") {
          System.Web.UI.WebControls.TextBox txt = new System.Web.UI.WebControls.TextBox();
          txt.Enabled = false;
          txt.Width = 35;
          txt.Height = 30;
          txt.BackColor = ColorTranslator.FromHtml("#FD0707");
          e.Row.Cells[2].Text = "";
          e.Row.Cells[2].Controls.Add(txt);
                
        }
      
     }


 }

What are you doing on postback? Are you calling for the grid to load again? Based on what you shared the textbox won't show because a postback has occurred there for not calling the Load() method. Does removing the !PostBack check and just calling load every time resolve your issue?

 protected void Page_Load(object sender, EventArgs e)
    {
       Load();

    }
