Databinder.eval inside gridview inside repeater - c#

Is there a way to put the following code in a gridview so I can do paging without updating the entire page.

asp.net - SelectItemTemplate doesn't work

I have two tables. First works fine - if button ID="Button1" CommandName="Select" pressed selected item turns red. But second table doesn't do the same if I pressed it's own button ID="Button2" CommandName="Select".
first table listView ID="ListViewGrSDtudents"

Databinding multiple records to a single vertical-column table in asp.net gridview

I fetch data by using a selectmethod and it works fine , the problem is that I don't want a new table for each record inserted. I'd like a new column to be added to the existing table. Something like the picture below
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<asp:GridView ID="FormView1" runat="server" ShowHeader="False" ItemType="MieleRepresentative.SteamBoiler" SelectMethod="GetSteamBoilerModels" RenderOuterTable="false" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<table class="table-striped table-bordered">
<tr style="background-color: thistle!important;">
<td style="font-weight: bold;">Model</td>
<td><%# Eval("Model")%></td>
</tr>
<tr>
<td style="font-weight: bold">WorkingPressureLimit</td>
<td><%# Eval("WorkingPressureLimit")%></td>
</tr>
<tr>
<td style="font-weight: bold">TestPressureLimit</td>
<td><%# Eval("TestPressureLimit")%></td>
</tr>
<tr>
<td style="font-weight: bold">Electrical</td>
<td><%# Eval("Electrical")%></td>
</tr>
<tr>
<td style="font-weight: bold">Diameter</td>
<td><%# Eval("Diameter")%></td>
</tr>
<tr>
<td style="font-weight: bold">Height</td>
<td><%# Eval("Height")%></td>
</tr>
<tr>
<td style="font-weight: bold">Weight</td>
<td><%# Eval("Weight")%></td>
</tr>
</table>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
public IQueryable<SteamBoiler> GetSteamBoilerModels([QueryString("productID")] Guid productId)
{
var _mieleDbEntities = new MieleDBEntities();
return _mieleDbEntities.SteamBoilers.Where(boiler => boiler.FKProduct == productId);
}

If you want a table with an undefined number of columns (one for each record selected), probabily GridView is not your best bet.
In my opinion you should build dynamically your table in .aspx page in this way:
<% var steamBoilersList = GetSteamBoilerModels(...params...); %>
<table>
<!-- first row -->
<tr>
<% foreach (var singleSteamBoiler in steamBoilersList) { %>
<td>
<%= singleSteamBoiler.FIELD1 %>
</td>
</tr>
<!-- second row and so on -->
<tr>
<% foreach (var singleSteamBoiler in steamBoilersList) { %>
<td>
<%= singleSteamBoiler.FIELD2 %>
</td>
</tr>
</table>

how can i divide two eval variables

i tried and get the sum of two numbers by getting through eval
<%# Convert.ToDecimal(Eval("total"))+ Convert.ToDecimal(Eval("tax")) %>
by doing this i got the sum of (total + tax)
now i need to find the division. Is it possible to divide like <%# Convert.ToDecimal(Eval("total"))/ Convert.ToDecimal(Eval("qty")) %> the above.
my code in detail
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>

please help me. thanks in advance

ListView sum column total and display in label returns null

I'm trying to sum all the values from the July column into a label with ID of july. Here's the markup:
<asp:ListView ID="leaveListView" runat="server" ItemPlaceholderID="itemPlaceholder" OnItemDataBound="leaveListView_ItemDataBound">
<LayoutTemplate>
<table class="budgetList">
<thead>
<tr>
<td>Project Number</td>
<td>Account</td>
<td>Project Name</td>
<td>July</td>
</tr>
</thead>
<tbody>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</tbody>
<tfoot>
<tr class="projectRowTotal">
<td>Project Totals</td>
<td></td>
<td></td>
<td><asp:Label ID="july" runat="server" Text=""></asp:Label></td>
</tr>
</tfoot>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr class="<%# Container.DataItemIndex % 2 == 0 ? "" : "even" %>">
<td><%# Eval("Project") %></td>
<td><%# Eval("Account") %></td>
<td><%# Eval("ProjectNumber") %></td>
<td><%# Eval("July") %></td>
</tr>
</ItemTemplate>
</asp:ListView>
I'm using the ItemDataBound event to sum, but it's returning null. This is the code-behind:
decimal july = 0m;
protected void leaveListView_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
july += Convert.ToDecimal(e.Item.FindControl("July"));
}
Label julySum = (Label)leaveListView.FindControl("july");
julySum.Text = string.Format("{0:C}", (decimal?)july);
}
What do I need to do to get this to work?

as my comments suggested, here is solution:
<table class="budgetList">
<thead>
<tr>
<td>Project Number</td>
<td>Account</td>
<td>Project Name</td>
<td>July</td>
</tr>
</thead>
<tbody>
<asp:ListView ID="leaveListView" runat="server" ItemPlaceholderID="itemPlaceholder">
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
<tr class="<%# Container.DataItemIndex % 2 == 0 ? "" : "even" %>">
<td><%# Eval("Project") %></td>
<td><%# Eval("Account") %></td>
<td><%# Eval("ProjectNumber") %></td>
<td><%# Eval("July") %></td>
</tr>
</ItemTemplate>
</asp:ListView>
</tbody>
<tfoot>
<tr class="projectRowTotal">
<td>Project Totals</td>
<td></td>
<td></td>
<td><asp:Label ID="july" runat="server" Text=""></asp:Label></td>
</tr>
</tfoot>
</table>
havent't actually tried it, but should work fine ... + in code, where you bind data:
leaveListView.ItemsSource = <data>;
// simply place the value in label directly
july.Text = <data.sum>
now just make sum in code and you're done, no need for itemdatabound event

e.Item.FindControl("July") return null because no control with that existing in the ListView
Solution
You want to store July's value into HiddenField (or some other field) so that you can retrieve them back in ItemDataBound event.
<asp:ListView ID="leaveListView"...>
<ItemTemplate>
<tr class="<%# Container.DataItemIndex % 2 == 0 ? "" : "even" %>">
<td><%# Eval("Project") %></td>
<td><%# Eval("Account") %></td>
<td><%# Eval("ProjectNumber") %></td>
<td><%# Eval("July") %></td>
</tr>
<asp:HiddenField runat="server" ID="JulyHiddenField"
Value="<%# Eval("July") %>"/>
</ItemTemplate>
</asp:ListView>
decimal july = 0m;
protected void leaveListView_ItemDataBound(object sender,
ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
var hiddenField = e.Item.FindControl("JulyHiddenField") as HiddenField;
july += Convert.ToDecimal(hiddenField.Value);
}
Label julySum = (Label)leaveListView.FindControl("july");
julySum.Text = string.Format("{0:C}", (decimal?)july);
}
For Good Design Practice
Please name your control properly. Eg. <asp:Label ID="JulyLabel" runat="server" Text=""></asp:Label>. Currently, you have no way of knowing is july is what.
