wanted to bind all the files of a directory named "ABC" to a data grid and show them in a .aspx file as downloadable contents. When the user clicks a certain file link, here, the download starts immediately.
I have developed my application using ASP.NET with Visual Basic. I have a table that contains 3 fields. The name of the table is "Customer" and the names of the fields are "Name", "Address", and "Amount". I have a gridview that displays these three columns. I want to summarize the value in the "Amount" column for each record and display the summarize value in the footer of the "Amount" column.
I added some code to the "ItemTemplate" and "FooterTemplate" of the template for the "Amount" field and wrote two functions One function adds the value of the "Amount" field to a variable called "TotalAmount" and the second function 'gets' the value stored in the "TotalAmount" variable.
I am not getting any error messages and all of the items are displayed in the gridview but I am not displaying anything at the bottom of the "Amount" column. What more do I need to do?
This is my code for the "Amount" template:
<asp:TemplateField HeaderText="Amount" SortExpression="Amount"> <EditItemTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Amount") %>'></asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("Amount", "{0:c}") %>'> <%#SumAmount(Eval("Amount")) %></asp:Label> </ItemTemplate> <FooterTemplate> <%#GetTotalAmount() %></FooterTemplate> <FooterStyle BorderColor="Black" BorderStyle="Solid" /> </asp:TemplateField> This is the code in my .vp file Dim TotalAmount as decimal 0.0 Function SumAmount(ByVal Amount As Decimal) As Decimal TotalAmount = TotalAmount + TotalAmount End Function Function GetTotalAmount() As Decimal Return TotalAmount End Function

I have a problem displaying data in a Grid View control when set a row to visible = false when a certain condition is true.
For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.
The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.
How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.
I have a grid view that I made dynamically based on a data table. The fields that are displayed on the grid view are as follows:
File Name File TyPe Uploaded On
Where as the data table on which this grid is based contains one extra filed that is
FileContents,
This filed contains the contents of the file in binary format retrieved from the data base.
Now I wanted to download the file say by clicking on the file name on the grid or even I an agree to add a Download button to the grid that will download the relevant file.
I've got and SqlDataSource bound to a GridView, and I'd like to return the value of one of the fields from the SqlDataSource during GridView.RowCreated (I think). At the same time, one of the fields I'm returning to the GridView has a Null value, which I'm cool with, but Runtime is complaining about it so how can I get around errors relating to Null values in my tables?
i have a grid view with some coulmns like Name,Phone no etc with Edit,Delete column in grid view. I click a row in grid view to Edit,it goes another page where i can edit all fields .Once i update i redirect the page to gridview. I want the grid view to remain in that particular page say 4 of the grid view
It happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:
I have grid view that be filled using code behind , and it be displayed with the default pagingmy problem is I want to add two label behind and after the paging links and fill them with certain text such this example
I am developing an ASP.NET 3.5 web application and I have a folder in the project which contains a list of documents which could be pdf or any of the MS office 2003 or 2007 supported file formats. I would like to display these files to my users as thumbnails (just like the way windows displays files). And when the user clicks on a file it has to prompt them to either save the file or open in the browser itself. How can I achieve this?
