グリッドビューで検索する単語を書くテキストボックスがあります。リサーチはグリッドビューの最初のページではうまく機能しますが、別のページに移動するとリサーチがリセットされます。
これが私のコードです:

}
}
private void BindData()
{
string query = "select * from Ressources";

GridView1.DataBind();
}

using (DataTable dt = new DataTable())

return dt;
}
}
}
}
protected void EditCustomer(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
this.BindData();
}

{

using (SqlCommand comm = new SqlCommand(Query + ";select * from Ressources", conn))
{

DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
}
}
}
protected void RowUpdating(object sender, GridViewUpdateEventArgs e)
{
...
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (GridView1.EditIndex >= 0)
return;
if ((e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate) &&
(e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header))
{
e.Row.Cells[3].Visible = false;
e.Row.Cells[4].Visible = false;
e.Row.Cells[6].Visible = false;
e.Row.Cells[7].Visible = false;
e.Row.Cells[8].Visible = false;
e.Row.Cells[10].Visible = false;
e.Row.Cells[14].Visible = false;
e.Row.Cells[15].Visible = false;
}
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
...
}
private void AddNewRecord(string URL, string Type_Source, string First_date, string Data, string Crawler_subcategory)
{
...
}
protected void Button1_Click(object sender, EventArgs e)
{
...
}
public void btnSearch_Click(object sender, EventArgs e)
{
string query = "select * from Ressources where data like'%" + txtSearch.Text + "%'";
SqlCommand cmd = new SqlCommand(query);
GridView1.DataSource = GetData(cmd);
GridView1.DataBind();
}
}
単語を検索するために使用される関数は、btnSearch_Click() という名前です。
よろしくお願いします。
ありがとうございました !
