No. StringBuffer is a Java class. It's StringBuilder both in VB.NET and C#.

use the following statement in your javascript
window.open("default.aspx","popupwindow","width=600,height=50px");

Why do you do a postback to call the Javascript? Do it all in the browser:
<input type="button" value="Button" onclick="OpenWindow();" />

Hi,
I have a content page and I have textboxes for name, address, phoneNumber, email address.
But how can i use the following javascript for form validation because in contentpage there
is no html head and body section.
function FormValidate()
{
if(this.txtPhone.value.search(/\d{3}\-\d{3}\-\d{4}/)==-1)
{
alert("The phone number you entered is not valid.\r\nPlease enter a phone number with the format xxx-xxx-xxxx.");
return false;
}
}
|
|

|

You can add a tag inside "asp:content" tag and call the javascript functions. e.g. -
asp:Content ID="Content1" ContentPlaceHolderID="ContentHolderID" Runat="server">
<script type="text/javascript" language="javascript">
function FormValidate()
{
....
Hope this helps.

Good afternoon,
I am fumbling my way thru my first ASP.NET project and I have a question about contentplaceholders.
I have a master page that has 3 contentplaceholders. Pages that derive from this master page have custom html\text content in the contentplaceholders.
I want to allow users the ability to change the customer html\text for a derived page.
The master page:
<code>
<asp:ContentPlaceHolder ID="phMain" runat="server">
<h3>News of the day!</h3>
</asp:ContentPlaceHolder>
</code>
I want to programmatically alter the content of "phMain" in the master page from "News of the day! to "News of the Hour" in a derived page. Is there a way to do this without having to add controls (a label or textbox) to the contentplaceholder?
Thanks.

First of all you will have to create some javascript to determine if there is a link.
Then tou add a call to this script the event "ontextchanged"
if there is a link you can style the text as a link (blue and underline), then you add some javascript to the click event on the textbox to make the link work (location.href....)
Tha disadvantage with this method is that all the text in the textbox will be treated as a link. You cant have the value "klikk on http://www.dummy.com" and make only the url a link...
Hope this helps.

Hi,
I am stuck now. I have a master page. and I have one dropdownlist in master page. When I click one item on master page it redirects to me some folder and opens the file in that folder.
I am using one javascript for opening the url. but if I include that java script it doesn't go to that
selectedIndexChanged property. because I need to know the infdex of selected item in the dropdownlist.
but if I remove the javascript it goes to selexctediIndexChanged property event. But I need jhavascript to call
I don't know where is the problem. Could you please help me to solve it.
Thanks.
Here is my code in master page
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataSet ds;
ds = AppName();
DropDownList2.Items.Add(new ListItem("--Select Application--"));
DropDownList2.AppendDataBoundItems = true;
DropDownList2.DataSource = ds;
DropDownList2.DataTextField = "AppName";
DropDownList2.DataValueField = "AppLocation";
DropDownList2.DataBind();
}
DropDownList2.Attributes.Add("onchange", "goToNewPage(this.value)");
}
here is my Java script
function goToNewPage(url)
{
window.location.href=url;
alert("hello");
}
Here is my selectedIndexchanged property
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
int index = DropDownList2.SelectedIndex;
DataSet ds1;
ds1 = AppName();
Session["apprightid"] = Convert.ToInt32(ds1.Tables[0].Rows[index - 1][1]);
int count = Convert.ToInt32(ds1.Tables[0].Rows[index - 1][1]);
}

If you're using SQL Server 2000 you could use Job Scheduling to update the table every so often.
|

How can Job Scheduling Solve problem of timer can you give me any idea.
I haven't gone through job scheduling ..........
Thank you

I have data in a table that I would like to display in a radioButtonList, inside a dataGrid. The fields are such: QuestionID, Question, Option_1, Option_2, Option_3, etc. All these options are different potential answers that the user can select by means of a radio button. I need the values from these Option fields to populate the radioButtonList List Collection. (These options are different for every row). Is there a way to do this?
Thanks in advance.
|
|
|
|

Can you help me understand, a bit more, I bulid lots of questionnaires that's all I do is bulid data collection forms, not understanding why you are loading your radio buttons in data grid?
Why don't you just put it all on the form, make the radio buttons post back, and on post back make visible what needs to be visible depending on the answer that was given with a switch?
|
|
|
|
|
Just so I can pull all the Question IDs, the Questions, and their optional answers from the database, in one simple select statement (if possible). If I used a form, you are saying populate a table with this information using a for-loop or something? I would still like to be able to use a RadioButtonlist that would automatically pull the choices from the database, instead of having to type them in, just in case there are changes to be made, so they don't have to be made in 2 spots.

You could still pull them all in, all the forms I do this On I can't post on here until I can spend some time deleting stuff out of them, got stuff I am not allowed to post because of were I work. I load everything into the page, and set it visible, on post back user answers the question for this on postback, sets the next correct option visible. Now what would suck is if they changed your varibles names..
|
|
|
|
|
I do not understand. How do you load everything onto the page after pulling from the DB? Are you also filling the RadioButtonList with info from the database? or are you typing this information in?

Just a second, I a am looking for an example

Hi, (I am a newbie to ASP.NET)...
I create an ASP.NET project in VS2005 and it gives an "object not found" or "cannot create object" error in the first line (no matter what the first line is!!)
I just create the webproject from its template and it gives this error!
Hint:
I am using Windows XP SP2 Home Edition (but I have installed IIS on it anyway), does this have anything related to my problem?
|
|
|
|
|
You usually get that error when you have an object that is null and you are treating it like it is not null.
I would suggest pressing F10 to step into your app. This should take you to the first line of the code. Keep pressing F10 until you find the object that is not set. Once you have found the object hopefully you will know what to do. If not respond back with what you find.
Hope that helps.
