Insert、Edit、およびDelete機能を備えたGridViewを作成しました。挿入はうまく機能しますが、削除と編集は機能しません。[削除] をクリックすると、行が自動的に削除されると思われますが、まだ存在するため発生しません。編集と同じ2番目の問題、[編集]をクリックしてから、そこで何かを変更してから[更新]をクリックします。クリックしても何も変更されず、GridViewでもデータは同じです。私は小さなものを逃していると確信しています...助けてください！
ここでは、HTML の背後にある C# コード、
protected void GridViewServer_RowEditing(object sender, GridViewEditEventArgs e)
{
GridViewServer.EditIndex = e.NewEditIndex;
BindGridView();
}
protected void GridViewServer_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridViewServer.EditIndex = -1;
BindGridView();
}
protected void GridViewServer_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridViewRow _row = GridViewServer.Rows[e.RowIndex];
Label servername = (Label)_row.FindControl("lblServerName");
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Database_Shared_NotebookConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("delete from tblServer where ServerName = '" + servername + "'", conn);
cmd.CommandType = CommandType.Text;
conn.Open();
cmd.ExecuteNonQuery();
GridViewServer.EditIndex = -1;
BindGridView();
conn.Close();
}
protected void GridViewServer_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow _row = GridViewServer.Rows[e.RowIndex];
Label servername = (Label)_row.FindControl("lblServerName");
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Database_Shared_NotebookConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("update tblServer set ClusterName = @ClusterName, Architecture = @Architecture, Database_Type = @DataType, Restriction = @Restriction, Business_Continuity_Plan = @BCP, Tenant_Code = @TenantCode where ClusterName = '" + servername + "'", conn);
cmd.CommandType = CommandType.Text;
//cmd.Parameters.AddWithValue("@ServerName", ((Label)_row.FindControl("lblServerName")).Text);
cmd.Parameters.AddWithValue("@ClusterName", ((DropDownList)_row.FindControl("DropDownClusterName")).Text);
cmd.Parameters.AddWithValue("@Architecture", ((DropDownList)_row.FindControl("DropDownArchitecture")).Text);
cmd.Parameters.AddWithValue("@DataType", ((DropDownList)_row.FindControl("DropDownDataType")).Text);
cmd.Parameters.AddWithValue("@Restriction", ((DropDownList)_row.FindControl("DropDownRestriction")).Text);
cmd.Parameters.AddWithValue("@BCP", ((TextBox)_row.FindControl("txtBCP")).Text);
cmd.Parameters.AddWithValue("@TenantCode", ((TextBox)_row.FindControl("txtTenantCode")).Text);
conn.Open();
cmd.ExecuteNonQuery();
GridViewServer.EditIndex = -1;
BindGridView();
conn.Close();
}
と
public void BindGridView()
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Database_Shared_NotebookConnectionString"].ConnectionString);
conn.Open();
string sqlquery = ("SELECT * FROM tblServer");
SqlCommand command = new SqlCommand(sqlquery, conn);
SqlDataAdapter adp = new SqlDataAdapter(command);
DataSet ds = new DataSet();
adp.Fill(ds);
GridViewServer.DataSource = ds.Tables[0];
GridViewServer.DataBind();
}
