how to join two datatable datas into one datatable to show in one gridview
i.e in 1 datatable i have username and pwd and in another datatable i have that user details. how to show all these in one datatable to get those values display in gridview(asp.net)
Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c)
c.Open()
if Not IsNothing(da) Then
da.Fill(dt)
[code]...
When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.
I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
Here's my code (it doesn't work right now).

GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) {
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
$(document).ready(function () {
$('.search_textbox').each(function (i) {
[Code] .....

<asp:UpdatePanel ID="ConstructionActPhaseUpdatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:gridview ID="PhasesTempGrid" ClientIDMode="Static" OnDataBound="PhasesTempGrid_OnDataBound" allowpaging="True" OnPageIndexChanging="PhasesTempGrid_OnPageIndexChanging"
