I have to select the dropdownlist and that string should be search in gridview and display in textbox.

Solution 2

C#

protected void SearchButton_Click(object sender, EventArgs e)
      {
          GridViewRow row;
          string _strText = SearchTextBox.Text.Trim();
          for (int i = 0; i < GridView1.Rows.Count; i++)
          {
              row = GridView1.Rows[i];
              string fl = ((row.Cells[1]).Text);
              if (_strText == ((row.Cells[1]).Text))
              {
                row.ForeColor=ColorTranslator.FromHtml("red");


              }
          }
      }

But it is not searching all pages.Only front page is searched,I want all pages should be search.

This should work. Have you tried paging through the results and seeing if all the relevant rows are highlighted?
