I have to fill a survey form with data from an oracle database.
We debate two ideas: use a dataset object or a XML file.
For XML file I would use forward only method of reading the file and not DOM, faster.
Is it more efficient generating the XML from database and then parsing the XML on the application server then using a data set returned from the database ?
Thank you

Since this is posted to the ASP.NET forum I'll assume you want to bind the results of your Oracle database query to controls on a webform. In that case a dataset would be the way to go. Using databinding this would be faster and easier than usage an XML file. You could also use XSLT to transform your XML into HTML but depending on your requirements to update or refresh the form it might not be viable.

Hello guys. I am using this sample out on http://samples.gotdotnet.com/quickstart/util/srcview.aspx?path=/quickstart/aspplus/samples/apps/cookies1/cookies1.src&file=CS\Customize.aspx&font=3 to perform some user based changes to the page (such as backgroundColor, font size etc) . It’s working just fine. But the page only updates the info that user selected from the drop down lists, when you click the submit button twice. Do you guys know why this might be happening??? In the button click events handler, this is what I’ve got:
public void btnSubmit_Click(object sender, System.EventArgs e)
{
HttpCookie cookie = new HttpCookie("preferences1");
cookie.Values.Add("ForeColor",ForeColor.SelectedItem.Value);
cookie.Values.Add("BackColor",BackColor.SelectedItem.Value);
cookie.Values.Add("LinkColor",LinkColor.SelectedItem.Value);
cookie.Values.Add("FontSize",FontSize.SelectedItem.Value);
cookie.Values.Add("FontName",FontName.SelectedItem.Value);
Response.AppendCookie(cookie);
if ( ViewState["Referer"] != null )
{
Response.Redirect(ViewState["Referer"].ToString());
}
}
Please check out the actual code sample at the link shown above.
Thanks
Tina

Think, its updating the cookie on the first click itself... But the retrieving process is not properly handled... Could you post your code?

Hi,
I am binding a site map data source to the menu control. Some node titles are very long. I sent the Menu Item width, but some items are still longer than others. Since the menu need to display vertically. That makes the menu look bad. Is there a way to make the menu text wrap automatically?
Any help would be appreciated!
Thanks in advance!

Hello all,
I'm using Visual Studio 2005 to build a small application for applying for a job. The applicant answers a series of questions and uploads their resume. Or they should be able to do so. The resume upload step isn't the last step in the wizard, and it appears that the value of the file upload control is lost between postbacks. Is there a simple way to fix this problem?

Hi,
Which event are you using with Wizard control, i.e. OnActiveStepChanged or OnFinishButtonClick?
The event OnActiveStepChanged posts back the page on every wizard step, while OnFinishButtonClick posts back page once only at the finishing step.
Hope this would be useful.

im very new to NET and i apologize if this is a fundamental question, but i need some help.
i have an ascx file (inherits a cs file) loaded into an aspx file. in this code example, i click on the ascx file's radiobuttonlist. the radiobuttonlist's onselectedindexchanged methods fires a method in the ascx cs file. the cs method takes the value from the ascx radiobuttonlist and sets a cs property to the radiobuttonlist's selectedvalue. also, it takes sets a literal in the ascx file to the property value. in the aspx file, during the page_load, i call the ascx file's property and set the value to a literal inside the aspx file (but not in the ascx file). the code kind of works, but it's one click late. when i change the ascx radio buttons, the ascx literal updates. however, intially, the aspx literal does not change. the aspx literal does not change until the second radio button click.
i would greatly appreicate any help with this one. thanks from a newbie
void Page_Load(object s, EventArgs e)
{
string strControl;
Control ctl;
strControl = "radio";
ctl = LoadControl(strControl + ".ascx");
//((radio)ctl).choiceValue = "";
pl_radio.Controls.Add(ctl);
litResult.Text = ((radio)ctl).choiceValue;
}
<title>Radio Default File

i found the answer in google. by adding the loadcontrol in the aspx page_init and then retreiving it in the page_load, i was able to get the ascx property value after each radiobutton click.
<%@ Page Language="C#" AutoEventWireup="true" %>
protected Control ctl;
string strControl;
void Page_Init(object s, EventArgs e)
{
strControl = "radio";
ctl = LoadControl(strControl + ".ascx");
//((radio)ctl).choiceValue = "";
pl_radio.Controls.Add(ctl);
}
void Page_Load(object s, EventArgs e)
{
litResult.Text = ((radio)ctl).choiceValue;
}
<title>Radio Default File
<asp:placeholder id="pl_radio" runat="server">
From ASCX choicevalue property set during button click or radio select change :
<asp:literal id="litResult" runat="server">

Does anyone knows the way to parse (extract) data from Excel and CSV files?
Any help is appreciated.
Thank you,

Eventhough I haven't come through that case, you can try OleDB or Excel.Application...

Nice homework assignment. First year, I see.
Is this JavaScript (as in title) or VB.NET (as in this forum).
|
|
|
|
|
Try this javascript function. This might be helpful.
function ChangeToCurrency (TargetString)
{
var Index;
if ((Index = TargetString.indexOf(".")) == -1)
TargetString += ".00"
else if (TargetString.substr(Index + 1).length == 0)
TargetString += "00"
else if (TargetString.substr(Index + 1).length == 1)
TargetString += "0"
return (TargetString);
}

I have
<%@ Register TagPrefix="spm" Namespace="SolpartWebControls" Assembly="SolpartWebControls" %>
and
<spm:solpartmenu ...(options go here)... />
In my Bin folder is the SolpartWebControls.dll that this is referring to.
It all works great but I have a red line under solpartmenu and says "Element 'solpartmenu' is not a known element. This can occur if there is a compilation error in the Web site." and if I go to Design view I get "Error Rendering Control - PageTable An unhandled exception has occurred. Request is not available in this context". I normally wouldn't care but this is on a master page so all pages using is can't be viewed in design mode. I have very basic users that will be creating the other pages and if they can't use Design more then they can't create their pages.
Any help would be great, thanks.

I have a form that has 2 sections.
Each section has a textbox/ fileupload control and a button.
I want to add a RequiredFieldValidator for the textbox/ fileupload control and want to activate the validator only to the controls in that section, when the button in that section is clicked.
When Button1 is clicked, then RequiredFieldValidator for textbox1 in section1 should get activated and not the RequiredFieldValidator of the control textbox2.
How do I do it?
Thanks
