Hi,
I am beginning with asp.net and I have downloaded the following: VS Express 2012 (with asp.net 4.5 ) and sql server express from www.asp.net/downloads
I want to download some simple asp.net (c#) projects which will give me a basic understanding of the fundamentals of asp.net. e.g simple tricks and tips to do tasks in asp.net. Please advice.

Hi,
I need to export file in xlsx format. My code is bellow:
string Path = strFullTo + "Balancing_" + String.Format("{0:MMddyy}", DateTime.Now) + ".xlsx";
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWriter);
GridView DataGrd = new GridView();
System.IO.StreamWriter vw = new System.IO.StreamWriter(Path, true,System.Text.Encoding.Default);
stringWriter.ToString().Normalize();
string style = @" .textmode { mso-number-format:\@; } ";
vw.Write(style);
vw.Write(stringWriter.ToString());
vw.Flush();
vw.Close();
But my problem is when I am trying to open the xlsx file it is saying "File format or extension is not valid".
I need to keep the data in xlsx file. Please help.
Thanks & Regards
Mishra

You need to export as .xls instead of .xlsx. .xlsx is more of an xml format but .xls can support html format, which is essentially what you are doing.
There are only 10 types of people in the world, those who understand binary and those who don't.

I have created a treeview, which is binding categories and subcategories from database.
I want to display an icon (image) on left side of the treeview. For example, in treeview I have categories such as amana tool as a parent node and the router bits as child node of amana tool. So, in database I have icon of amana tool as well as icon of router bits. Now, I am able to show categories (amana tool) only in treeview. But, I need that left side should show the icon of the related categories and then categories name(amana tool).
Note: The icon should bind from database but it should not be static icon because I need to show more than 100 categories and the icon existing in database.
Please help me out.
Here my code works correctly , further what i have to do?

This is a treeview I made for ckEditor, it's all code in vb, but you should get the idea. It was created on Protected Sub OnInit().
As you create more nodes, just add the new image url
tv_FileBrowser_Content_Navigation = New TreeView
With tv_FileBrowser_Content_Navigation
.ID = [ID] & "_tv_FileBrowser_Content_Navigation"
.Style.Add(HtmlTextWriterStyle.Width, "90%")
.Style.Add(HtmlTextWriterStyle.PaddingTop, "25px")
.ExpandDepth = 10
.ImageSet = TreeViewImageSet.XPFileExplorer
.NodeIndent = 10
.ShowLines = True
.ShowExpandCollapse = True
.PathSeparator = Convert.ToChar("/")
.NodeStyle.ForeColor = Drawing.Color.Black
.NodeStyle.HorizontalPadding = 6
.NodeStyle.VerticalPadding = 0
.NodeStyle.NodeSpacing = 0
.RootNodeStyle.HorizontalPadding = 6
.ParentNodeStyle.ImageUrl = cs.GetWebResourceUrl(rsType, "Admin_PM_Standard.folder_0.png")
.ParentNodeStyle.HorizontalPadding = 6
.SelectedNodeStyle.ForeColor = Drawing.Color.Black
.SelectedNodeStyle.BackColor = Drawing.Color.LightGray
.SelectedNodeStyle.Font.Underline = False
.SelectedNodeStyle.HorizontalPadding = 6
.SelectedNodeStyle.VerticalPadding = 0
.HoverNodeStyle.Font.Underline = True
.HoverNodeStyle.ForeColor = Drawing.Color.Black
.HoverNodeStyle.BackColor = Drawing.Color.LightGray
node_Editor = New TreeNode("File Browser")
node_Editor.Selected = True
node_Editor.SelectAction = TreeNodeSelectAction.Expand
node_Editor.Text = "File Browser"
node_Editor.Value = "/Product/editor"
node_Editor.ImageUrl = cs.GetWebResourceUrl(rsType, "Admin_PM_Standard.myComputer.png")
.Nodes.Add(node_Editor)
'########################################################
'
node_Files = New TreeNode("files")
node_Files.CollapseAll()
node_Files.Selected = False
node_Files.SelectAction = TreeNodeSelectAction.Expand
node_Files.Text = "files"
node_Files.Value = "files"
node_Files.ImageUrl = cs.GetWebResourceUrl(rsType, "Admin_PM_Standard.folder_0.png")
node_Editor.ChildNodes.Add(node_Files)
'########################################################
'
node_Flash = New TreeNode("flash")
node_Flash.CollapseAll()
node_Flash.Selected = False
node_Flash.SelectAction = TreeNodeSelectAction.Expand
node_Flash.Text = "flash"
node_Flash.Value = "flash"
node_Flash.ImageUrl = cs.GetWebResourceUrl(rsType, "Admin_PM_Standard.folder_0.png")
node_Editor.ChildNodes.Add(node_Flash)
'########################################################

node_Images = New TreeNode("images")
node_Images.CollapseAll()
node_Images.Selected = False
node_Images.SelectAction = TreeNodeSelectAction.Expand
node_Images.Text = "images"
node_Images.Value = "images"
node_Images.ImageUrl = cs.GetWebResourceUrl(rsType, "Admin_PM_Standard.folder_0.png")
node_Editor.ChildNodes.Add(node_Images)
'########################################################
'Context Menu's
'########################################################
AddHandler .SelectedNodeChanged, AddressOf tv_FileBrowser_Content_Navigation_SelectedNodeChanged
AddHandler .TreeNodeExpanded, AddressOf tv_FileBrowser_Content_Navigation_TreeNodeExpanded
AddHandler .TreeNodeCollapsed, AddressOf tv_FileBrowser_Content_Navigation_TreeNodeCollapsed
End With
panel_FileBrowser_Content_TreeView.Controls.Add(tv_FileBrowser_Content_Navigation)
As you create each addtional node, you add the image url.
I know you can use an embedded image, but not sure how to use a database blob.
[edit]
I only created the first level nodes in the initial treeview. The child nodes are populated on demand, when a parent node is expanded, so an event handler was added to detect expand node, and upon expansion, the child nodes are added according to the parent node type or name.
I had load time issues on the first couple of tries, and had to speed it up a bit.

I am developing a web application, which have to get the data from selected Excel file and save it in SQL Database.
I want to select Excel File in runtime using the FileUpload control. Is this possible..? Please guide me..
|

hi SravanKumar-A,
yes it's possible....
first, his first save the file when uploaded, this means stored on the Server side, here you set it to accommodate PathLocation Files uploaded the results ..
then, you read his file based PathLocation excel file it in the store ..
how to read the contents of the data from the Excel file, you can googling, a lot of his examples ..
You must read the contents of his excel how many rows,
then you loop through the contents of each row to get her,
then you input into a database row-a row ..
after that you delete the file upload it if you save the file you do not use anymore ..
yes, this is just a logical course to determine the appropriate code logic what its like ..

Did you transmit this?, or did you receive this?
In the quote above, the 2nd XML field corrupted, probably because you did not encode the entire package before transmitting to the server. I suspect you may have international chars in the values.
The server was looking for UTF-8 encoding, but I'm not sure what the package looked like before you transmitted it, or what the response is suppose to look like as well.
You may of transmitted garbage to the server when making your web request, and received back garbage as an error. If the web service was well written, in which I don't know, then you should of got back a clean XML Text of the error.
[FYI]
Looking at the data, I remember a post several months ago from an OP that was working with airline ticket data, looks similar to yours, but the data was packaged as a delimited char array, and was not XML or WSDL. I see the same data structure in the posted code dump that I saw in that OPs post.
If your the same guy or gal, so you probably explain what your up to here, so we can get a better idea of how to help you.

This looks like a call to a web service using XML, but is really a server that splits out delinted text. There is a char value missing that seperates each field that is not showing above.
You simply don't understand what your working with here.
It's a fixed response. It's always let's say, 80 items, always in the same position. Kind of like a floppy disk, which is divided into 80 sectors. But I digress,
1 - 03903
2 - Business
3 - Post
4 - Paid
5 - Contact
and so forth until the end
So you figure how to just request the response, decode the response, and split the value into an array string or list or something, then you can access each value by number, so if you want value 1, you look for response(1)
Maybe somebody else can expand or help out further.

hi, friends,
I am developing the web app for touch device.
I have the gridview inside the DIV, showing the list of data.
if I used the scrollbars for this div, it is no good to scroll by touching on touch device.
I want to scroll up/down on the gridview content like the swiping.
because, the users will try to swipe the DIV by touching rather than scrolling on the scrollbar.
how can I achieve?

Dear All,
I have a question regarding data access from SQL server 2008 to Asp.net 4.0 application... My question is what is the best method to get data from SQL Server, Table, View, Stored Procedure, function.. My Problem, why I am asking this question, I want to access data from Stored Procedures and I have to define parameters on creation time of procedures and have to use them all in asp.net form to access data. But I want to give rights to user, get data with nos of parameter if he wants to use otherwise no filter all data would be displayed... and he has right to use all filters or no filter or whatever that is defined. So in this situation what would you guys recommend to get data from SQL using Stored Procedure, Tables or Views and how is that possible?
Thanks in advance for your reply
