Asp .Net GridView

Question

Hi,

  I have added  one row dynamically below gridview header for inline search.I want to get value of these textbox on postback.

 for dynamic row:

GridViewRow row = new GridViewRow(0,0, DataControlRowType.Header, DataControlRowState.Normal);

for (int i = 0; i < GridView1.Columns.Count; i++)

{

TableHeaderCell cell = new TableHeaderCell();

TextBox txtSearch = new TextBox();

txtSearch.Visible = true; txtSearch.Width = 140;

txtSearch.CssClass = "form-control";

txtSearch.ID = "txt1";

cell.Controls.Add(txtSearch);

row.Controls.Add(cell);

}

GridView1.HeaderRow.Parent.Controls.AddAt(1, row);

}

 

thanks
