I am using listview to show the data in my application...
Populate ASP.Net ListView from database and Repeat columns horizontally using GroupTemplate but the problem is that when i am doing GroupItemCount="4" its still showing the 3 items in a row.
I am trying to export a Nested Listview to Excel, but I am having issues with the code recognizing the records in the ListView. When I do a FindControl, that code works fine.The Issue arises when I try to loop through the Items of the Nested Listview. The Count always comes back as 0 (zero). However, if I do a watch on the nested listview variable and navigate to the Items collection, then the count is updated with the correct content. I've tried forcing a Databind() on the 2nd Listview, but that really shouldn't be necessary as I know the records are there. As a result, I am having issues Exporting the Data to Excel since only data from the Parent ListView is returned.

I am working on my first project with the Entity Framework and am having some difficulty displaying advanced information with the EntityDataSource and a ListView.
For example, given the two entities:
Item
Name
Price
Order
Number
Items <---- Navigation Property to Items contained in the Order
I want to display a list of all orders with a column with the total number of items in the order and a column with the sum of the prices of all items in the order.
I am using an EntityDataSource configured as follows:
<asp:EntityDataSource ID="eds" runat="server" ConnectionString="name=NDSEntities"
DefaultContainerName="NDSEntities" EnableFlattening="False" Include="Items"
EntitySetName="Orders"></asp:EntityDataSource>
In the ItemTemplate of the ListView, I can write the order number as follows:
<%# Eval("Number") %>
I had trouble figuring out how to display a count of items in the order. I tried using Items.Count() function in select statement in the EntityDataSource but that didn't work. Eventually I figured out I could do the following in my ItemTemplate:
<%# Eval("Items").Count() %>
Now I am stuck trying to get the sum of the items. I am stuck here. I have tried using
<%# Eval("Items").Sum(Function(i) i.Price)%>
but I get the following error:
Public member 'Sum' on type 'EntityCollection(Of Item)' not found.
This confuses me because I know that Sum is a method of EntityCollection(Of ).
My two questions are as follows:
Am I getting the item count correctly?
How should I go about getting the sum of the prices of the items?
I'd like take both C# and VB.NET suggestion. I have a simple ListView with DataPager like the following:
<asp:ListView ID="lvStudent" runat="server">
<LayoutTemplate>
<table id="TimeSheet" cellspacing="1" class="tablesorter">

I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?

View 9 RepliesWhen a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

I am working on a screen where in it has a typical 2 listboxes & 2 buttons(add/remove), so when these buttons are clicked the items have to move from one listbox to another. its all working fine with javascript.but the issue is, I am not able to get the items of the 2nd listbox in the codebehind. I tried with html & asp.net listbox controls. I even tried to access the listbox using Request.Form["ControlName"] - which gives a null value.In the listbox1 the data's are coming from database.The data's choose from listbox1 will be moved to listbox2. And again i have to update this data to one of database table.

I HAVE A GRID VIEW IN asp.net + VB Code. There is a drop down list and the selected data is displayed in web page. I placed a label in web page and code behind i used following code.

Label1.Text = GridView1.Rows.Count.ToString()
Dim ONYO As Integer = 0
Dim DONE As Integer = 0
For i As Integer = 0 To GridView1.Rows.Count - 1

In a custom server control, I am simply writing out the number of child controls.
Is there a reason that the count would go to zero if <% %> tags are used within the body of the control tags?
Here's my extremely simplified control:
public class Script : Control
{
public override void RenderControl(HtmlTextWriter writer)
{
writer.Write(this.Controls.Count.ToString());
}
}
When passed only Literal data, the count written is 1 as expected:
<my:Script runat="server" ID="script3" >
function foo(){}
</my:Script>
When passed Literal data and some computed data, the count goes to zero:
<my:Script ID="Script1" runat="server" >
function foot(){}
<%=String.Empty %>
</my:Script>
There's nothing special about the String.Empty either. Anything I put here results in a count of zero.
Interestingly enough, other Control tags work fine however. The following counts 3:
<my:Script runat="server" ID="Script2">
<asp:HyperLink runat="server" NavigateUrl="/" Text="hi" />
</my:Script>
Is there another way to get the child "content" of the custom control? I would think there is some way, as does it, but I can only inspect the metadata for System.Web.UI.WebControls.Content - not the implementation.
Look at the below picture I want to count value of last column (cnt) I am using repeater control.
example:
if (last column (cnt) is greater than 5> ) {
response.write ("yes");
}
SQL Query
SELECT id, category, ( SELECT COUNT(id) FROM entry_table WHERE category.id = entry_table.Cat_id) as cnt FROM category
<asp:Repeater ID="CloudTags" runat="server" OnItemDataBound="CloudTags_ItemDataBound">
<ItemTemplate>
<asp:HyperLink ID="HyperLink9" runat="server">

int countControl=gridView.Controls.Count; not work.

but lnkEdit is always null.
I wonder why it is not able to find the control while I can see it in page view source.
I have a Listview that houses a FileUpload control. However, after using findcontrol the next line of code tries to convert the filename into a string and produces the familar error object reference not found.
Note: I have used identical code in a formview and it works fine.
Here's my relevent codebehind:
protected void AccessDataSource1_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
FileUpload FileUpload1 = (FileUpload)ListView1.FindControl("FileUpload1");
string Fupload = FileUpload1.FileName.ToString();
DateTime DateNow = DateTime.Now;
string DateNowSTR = DateNow.ToString();
string NewImageName = DateNowSTR + Fupload;
FileUpload1.SaveAs(Server.MapPath("~//images//" + NewImageName));
e.Command.Parameters["SponLogo"].Value = NewImageName;
}
Why do we use this in ListView?
<tr
id="itemPlaceholder"
runat="server"
/>
