Re: Download link of the generated file changed when I moved the code to a new pop-up page

I this it may be the issue of reading file form the server machine so you have to set account of the person who can access the local file system form server to do this :

go to IIS Manager > right click on DefaultAppPool
>> Go to poperties >> Go to Identity Tab >> set security account to local system

Hi, thanks for your reply. I don't think this is the problem because it can properly download the file if I revert back my changes in the server. The old code and the new changes both access from the same file location.

this is a big headache

I finally found the solution!
I also had to clear the headers of the response, apparently, Response.Clear() only clears the content.
Maybe the header was somehow populated incorrectly by the new pop-up page.

So the fixed method is:

public static void Export(Page webPage)
{
    webPage.Response.ClearHeaders(); //added
    webPage.Response.Clear();
    webPage.Response.Buffer = true;
    webPage.Response.Charset = "";
    webPage.EnableViewState = false;

    string filename = "spreadsheet.xls";
    webPage.Response.ContentType = "application/vnd.ms-excel";
    webPage.Response.ContentEncoding = Encoding.Default;
    webPage.Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName + ";");

    string filePath = string.Format("{0}temp\\{1}", webPage.Request.PhysicalApplicationPath, fileName);
    populate(filePath);

    webPage.Response.TransmitFile(filePath);
    webPage.Response.Flush();
    File.Delete(filePath);

    webPage.Response.End();
}

Thanks to all who wanted to help! Smile | :)

How to Search PartList Entity Using ASP.NET Dropdowlist and Textbox

Sid Childers25-Feb-10 11:21

Hello,

I have defined an entity data model in my ASP.NET VB project that contains a PartList entity. I have created an entitydatasource that returns the Part Name, NSN and RecID (primary key). I have also created a dropdown list that contains values PartName and NSN and a textbox that will contain the search criteria.
How would I define my entitydatasource parameters to query it.[NSN] if dropdownlist.selectedvalue = NSN and query it.[PartName] if dropdownlist.selectedvalue=PartName and submit the textbox.text as the search string? Is gridview a good candidate to display the results? Should the search controls and gridview be placed on the same page or separate pages? Finally, the ultimate goal is for the user to click the checkbox next to the parts they want and those selected parts are passed on to a wizard control. Do I use stringbuilder to get the selected parts and send them to the wizard control?

Thanks,
Sid

Change border properties of ASCX from code-behind?

mittalpa25-Feb-10 8:15

Hi I am building a library of asp.net user controls which I am deriving from a custom UserControlBase class which further derives from actual UserControl class. Hierarchy looks like this :

ASCX -> UserControlBase : UserControl

I have this requirement to put a border around all the ASCX's. So, I thought if I can modify UserControlBase it will apply to all ASCXs. I tried following code in Page_Load of UserCOntrolBase but its not working

this.Attributes.Add("style", "border-color:#FFFF66;border-width:4px;border-style:Dashed;");

What should I do to make it work? Please advise.

Thanks
AJ

You should use CSS classes rather than hard code these values. When users ask to change it, and they will, it will be much easier.

Create a div in the control to act as the border and set its properties not the control itself.

they have used UserControl. u just try without UserControl, the method is very simple. just have a look

1. call the RSS content with its URL. It will return XML
2. Convert XML to dataset
3. Since u got the dataset you know what to do
4. Show That in u r page/ if u want u can store that also for future.
5. If u want to format the resultant XML use XSLT

Hi there.. Smile | :)

im workin on a website at the moment in asp.net, using vb.net, in the visual studios 2008 IDE! i just wish to add an extra feature and hopefully someone out there might be able to help.
I have a button that reads the values of 5 radio buttons in a radiobutton list, then queries the database, returning results based on the values selected. If no value is returned i wish to display a message saying "No Results this time, please search again" or something to that effect. Im not sure how to do this. here is the code i have behind the button.. Please advise.

Protected Sub btnSuggest_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSuggest.Click

Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim dr As SqlDataReader
Dim varBatteryLifeQ As String = ""
Dim varMemoryQ As String = ""
Dim varRam As String = ""
Dim varScreenSize As String = ""
Dim varWebcam As String = ""

myConnection = New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True")

myConnection.Open()

varBatteryLifeQ = RadioButtonList1.SelectedValue.ToString
varMemoryQ = RadioButtonList2.SelectedValue.ToString
varRam = RadioButtonList3.SelectedValue.ToString
varScreenSize = RadioButtonList4.SelectedValue.ToString
varWebcam = RadioButtonList5.SelectedValue.ToString

myCommand = New SqlCommand("Select * From LPU400 Where BatteryLife = '" + varBatteryLifeQ + "' AND Memory = '" + varMemoryQ + "' AND RAM ='" + varRam + "' AND ScreenSize ='" + varScreenSize + "' AND Webcam ='" + varWebcam + "'", myConnection)
SqlDataSource2.SelectCommand = "Select * From LPU400 Where BatteryLife = '" + varBatteryLifeQ + "' AND Memory = '" + varMemoryQ + "' AND RAMQ ='" + varRam + "' AND ScreenSize ='" + varScreenSize + "' AND Webcam ='" + varWebcam + "'"
SqlDataSource2.DataBind()

dr = myCommand.ExecuteReader()

While dr.Read()

End While

dr.Close()

myConnection.Close()

End Sub

Thanks in advance,

Before you proceed with dr.Read() check if dr.HasRows. If yes proceed to read, else put "No Results this time, please search again" in a label or some other place holder.

Hi,
I want to develop an application using asp.net in which user can create reports by dropping labels and database fields and move and place them any where they like in other words design report as per there requirement (during runtime) and then save that format and call that report. Is there any possiblity to make such application.
waiting for your response.

Yes its possible, but u need to predefine the Report format(if u want different types of format) or else fix the format(controls that are dropped/Selected by user will be placed in left to right format only) and u can achieve the user generated report.

i have done this in one of projects
