I need a list to export in excel and i need the following to achieve in the exported excell
- I need the header of the excel with font bold and size should be 14px of font.
- Other Cell try should be 12px of the font
- Right align the particular column in the excel
The code on one of my aspx pages is giving me this error:
I'm getting this on the code behind for export to excel on one of my pages.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).It is referring to this line Me.GridView1.Parent.Controls.Add(frm)
I have this code in the aspx page. I am using two gridviews. I need to have this on the page any way I can fix the code so I can use that export to excel you created?
<% If(Session("PendingClaims"))%>then display gridview1<%Else%>
Then display gridview2<% End If %>
I was building an application for a project with .NET 3.5 and I noticed a weird behaviour of the List.Add method:
I have built my own class to organize data pulled from a database, and I use a while cycle to iterate through it.
However, when I List.Add(item), the whole content of the list is substituted with the last content pulled.
An example:
Suppose you have 3 users in a DB, each one identified with an ID and a username:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
and you have a "Users" class defined as
public class Users
{
private Int32 iD;
private String username;
public Int32 ID
{
get { return iD; }
set { iD = value; }
}
public String Username
{
get { return username; }
set { username = value; }
}
}
So you write this function:
[... SQL definitions - sdr is a SqlDataReader ...]
List<Users> userlist = new List<Users>();
if (sdr.HasRows) //There are users
{
Users user = new Users();
while (sdr.Read())
{
user.ID = sdr.GetInt32(0);
user.username = sdr.GetString(1);
userlist.Add(user);
}
}
What you expect (I expect) is userlist containing:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
What I actually get is, instead
| ID | username |
| 3 | Paul |
| 3 | Paul |
| 3 | Paul |
I need to cache System.Collection.Generic.List object with expiration time
var Root = from feed in feedhotel.Descendants(ota + "HotelContent")

Is it possible to cache Root.ToList() for some time....

I simply want to be able to apply htmlattributes / styles to my select box
[Code]....
I have a GridView control (GridView1) on a page which is reading from a database. I already have a CSS style applied to the GridView and all I want to do is change the background image applied in the style depending on if a certain cell has data in it or not.
The way I'm trying to handle this change is updating the CSS class applied to each row through C#. I have the code below doing this:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow row = e.Row;
string s = row.Cells[7].Text;
if (s.Length > 0)
{
row.CssClass = "newRowBackground";........
It seems as if the top piece of code is always returning the string with a value greater than 0, but when I check the database the fields are all null (except for my test record of "Smith").
I'm probably doing something very simple that's wrong here, but I can't see what. Like I said, I'm still very new to this. One thing I have tried is changing the argument in the if statement to things like: if (s != null), if (s != "") and if (s == string.empty) all with no luck.
I can't seem to figure out. Here is my simple .css file:
#divBody
{
margin-left:25px;
}
#divTrans
{

I'm trying to export data from an asp.net page to an Excel file and I'm basically just outputting HTML to the XLS file and let Excel interprets it, by using this type of coding:
[Code]....
Although this is doing fine for exporting raw text, I now have to export to the same Excel file an image. However, the same kind of method I'm using right now only seems to insert a "linked" image, I mean, the image appears in the file, however, the user viewing the file has to be online since it's a direct link to the file in the server. I would like to able to "embeded" the image in the file, just like how it's made when you insert manually an image using Excel.
However, after some online research I can't seem to find any solution for this.
I can't use Microsoft.Office.Interop.Excel library, and a third party software isn't advisable also, that's what made me try out the HTML output solution, which worked ok for the text. But now, for inserting an image, what can I do? Is it possible to achieve what I pretend?
I need to export SQL query results to an Excel file.
I use the following code to do it.
[Code]....
Works fine for majority of the cases. There is a column called Description in the query results which is of type nText in the sql database. This can have lengthy data ( couple fo paragraphs) . When the number of charcters are large only the first portion of the data is showed and it trims the rare portion. how I can avoid this? Or any efficient code example on how I can do this in a different manner

View 1 RepliesI am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet. If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown. A test program in windows form is also working fine regardless of how many rows.
Code has been simplified, "information ..." in the sql insertion command represents 1803 characters.
ExcelObjConn = "Provider=Microsoft.Ace.OLEDB.12.0;" & _
"Data Source=" & fileName & ";Extended Properties=Excel 12.0 XML"
ExcelConnection = New System.Data.OleDb.OleDbConnection(ExcelObjConn)
ExcelConnection.Open()
Try
SqlCommand = "CREATE TABLE ABC ([row1] text, [row2] text, [row3] text, [row4] text)"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
For i As Integer = 0 To 1124
SqlCommand = "Insert into ABC ([row1], [row2], [row3], [row4]) Values ('information...', 'information ...', 'information ...', 'information ...')"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
Next
Catch ex As Exception
Finally
If ExcelConnection IsNot Nothing Then
ExcelConnection.Close()
ExcelConnection.Dispose()
End If
End Try
I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
I need a code which can export the data from XML file to the Excel file.

I have a web form that contains a GridView, which impliments Search in Grid with a TextBox and Button control in the footer. This works as I have it now. I have also implimented a Export to Excel function. The Export to Excel works by itself if the Search in Grid function is not included in the footer.The Export to Excel function errors when trying to render the Grid for the export. Is there a better way to incorporate both functions and accomplish the same thing? Am I missing something simple?
