i am doing an application, in which i want to search records from dataset. after this
i want to bind data to datatable from a datarow.

the code i used was

DataSet dsSearch = new DataSet();
dsSearch.ReadXml(Server.MapPath("~/XMLFiles/Users.xml"));

DataRow[] dRow = dsSearch.Tables[0].Select("Name='" + txtName.Text + "'");

DataTable dTable = new DataTable();

after this how can i import the dRow into a datatable or dataset and bind it...

any help would be appreciated....?

"Winners don't do different things. They do things differently. ...

An array of datarows is a valid data source, so you don't need the datatable.

You can implement like this
You have to loop thru DataRow array and add Like this

DtaRow dr=dRow[index]
dTable.Rows.Add[dRow[index]]

Hai

Iam new to web applications. In my application try to add rows to gridview and save the row data in to sql server db.
My problems
-----------
1. While adding rows only one row is added. Trying to add another row firstly created row is removed and adds a new row. Cant add rows continuesly.

2. Only one SAVE button is there. While saving newly created ROW data cant inserted to db.

Pls help to find a solution.

Regards,
KP

The solution is to fix your code. It sounds like you're not saving your new rows, so they are lost. Why are you taking on something this complex when you're new to web apps ?

This is not a question, its just something that happened to me, and since it is related to web apps, im posting it here

A few days ago, i uploaded my app to the hosting server, i uploaded everything to a temp folder (PortalTemp) and i tought that then i would only rename the main folder (Portal) to Portal2 and PortalTemp to Portal, this way, the new version would be live, as you can imagine, it should take no more than a minute...
For my surprise, it took me almost a week!!!

Well...something went wrong a the server (Shared server where i dont have direct access and i only access it over FTP)
Suddenly, i wasnt able to rename PortalTemp to Portal (i had already changed Portal to Portal2)
So there i was, with the new version in PortalTemp Frown | :-(

I contacted godaddys support to tell them about the problem, and man, they are really slow
They take almost a day to answer
They dont have any idea of what they are doing
They even have to reccur to "Experts" in order to rename a folder, oh man, they just make me laugh
And this is the secont time that this happens to me Frown | :(

Im glad i dodnt call them, because im in mexico and it would have been really expensive to spend maybe a whole day on th phone talking to "Experts"

Here is the whole story:

ME
I dont know if ill have to spend another week just to rename a fuc#$% folder or what
It is always the same problem with your ftp applet
I cant rename a folder
I have this 2 folders on my root folder:
-Portal
-PortalTemp

Just change their names
Change Portal to PortalTemp
Change PortalTemp to Portal

And i dont want any excuses like the one below (Which just makes me laught, because it tells me that some people is really incompetent):

2. In the My Products section, select Hosting.
3. Next to the hosting account you want to modify, click Manage Account.

Dear Sir/Madam,

Thank you for contacting Hosting Support. After looking into your account, I have found that you have both sub-directories setup as IIS Virtual Directories. While these folders are set as Virtual Directories, you will not be able to rename or modify them. You will need to remove the permissions that you have set in the IIS Settings menu if you would like to change the folder names or delete them.

Please contact us if you have any further issues.

Im not sure if you know what you are doing, it doesnt look like you do
IIS virtual directories have nothing to do

I just removed the 2 virtual directories in iis and tryed to rename the folders
For Portal - I could rename this folder to Portal2 or any other name, but i changed it back because i couldnt rename PortalTemp
For PortalTemp - I could NOT rename this folder to any other name

Then i readded the 2 IIS folders and tryed to rename the folders, and i had the same results as when there were no virtual directories in iis (I could rename Portal to anything else)
So...IIS virtual directories have nothing to do

PortalTempis the onw locked, i tryed to rename it with your File Maneger and i received the Error: Rename failed

JUST RENAME THE FOLDERS AND I DONT WANT ANY MORE EXCUSES

Dear Sir/Madam,

Thank you for contacting Hosting Support.

We apologize for the inconvenience. Upon review of this issue it appears there was a permission issue with the PortalTemp directory. We have corrected this error and ensured that the directory names are able to be modified.

We have not taken action in renaming these directory on your behalf. We ask that this modification be completed by you. As such we suggest using either a third-party FTP client or our File Manger to accomplish this task. We appreciate you understanding.

Please contact us if you have any further issues.

I am new to web programming but have extensive experience with desktop apps. I have a question about asp.net. If I have two radio buttons called yes and no. If user checks no then I want a dropdownlist to become visible else invisible.

Now the questions I have are:
1. I created an event handler for the radio buttons which make the list visible and invisible. But if the AutoPostBack property is set to false then the event handler will only be invoked when a postback occurs (even by some other control), correct?
2. How can I make the list invisible and visible if postback is false? See if the AutoPostBack property of the radio button is false then its event handler is not fired upon check change. I want to make the list visible right away when the check changes.
3. What should I be aware of if AutoPostBack property is set to true? Any disadvantages or advantages?

1 - correct.
2 - the way you should do this is by using javascript, no need to do a postback just to make a control visible.
3 - a page that posts back all the time is a PITA, especially when people are used to AJAX.

Wrap the dropdown in a div tag, add a javascript function in the head of your page to alter the visibility of this div, and call it via onclick attributes added to your radio buttons in code-behind:

HTML:
<asp:RadioButton id="radYes" Runat="server" Text="Yes" GroupName="radYN"></asp:RadioButton>
<asp:RadioButton id="radNo" Runat="server" Text="No" GroupName="radYN"></asp:RadioButton>
<div id="divDD" style="display:none;"> 
<asp:Dropdownlist runat="server" id="ddlNo">

</asp:DropdownList>
</div>

JavaScript:
function toggle() {
if (document.getElementById("radYes").checked) {
document.getElementById("divDD").style.display = 'none';
} else {
document.getElementById("divDD").style.display = 'inline';
}

Code-behind:
radYes.Attributes.Add("onclick", "toggle()")
radNo.Attributes.Add("onclick", "toggle()")

And all achieved without postback - which should be avoided wherever possible as it (obviously enough) increases bandwidth as well as the load on the server.

why not just add the onclick inline ? Will ASP.NET wipe it for it's own ?

Christian Graus

well.. it's just the "proper" way to do it in Visual Studio!! VS will underline it in red and tell you it's not a valid property - which it isn't of the server control; it's only when the page renders it as an html control that it becomes so.

Fair enough. I'd tend to do it inline because I'd regard it as cleaner, and not be dictated to by the IDE. but, your way works, no doubt.

Phil,

Where in the code behind should I add the attribute to the collection? Page_Init()?

I have a DataSet with two tables with a relationship.

dataSetNodeData.Relations.Add(new DataRelation("Relationship", 
            dataTableTransmittal.Columns["Node ID"],
            dataTableDocuments.Columns["Parent"]));

This is working, but now the customer have changed the indata so Parent is now a commaseparated string with id numbers so the same document can belong to several Node ID's.

Can I make the DataRelation work with a commaseparated string? Or do I have to rewrite my application totaly?

No, that's not going to work. You need to rethink your architecture. I suspect you need to change your dataTableDocuments to have a record per parent id, even if they are stored as a csv. I'd say don't store them that way in the first place, just add records for each parent relationship.

Christian Graus

Yes, that's the way I thought that I hade to go.
I can't affect the indata as it is a export (xml) from a CMS system.

I have 5 radiobuttons. When i select one, it should be made bold. Other radiobuttons should be displayed with normal font. How to achieve this?

javascript. Handle the event and then use JS to bold the text. The text is in a label, it's actually not part of the radio button in HTML, so there's some hoops you'll need to jump through.

here is my code :

row["ReductionDetails"] = row["ReductionDetails"] + "" + Value
                         + "% of " + GetProductNameById(ProductId) + '\n';

what i want to get :

< td >
MY FIRST LINE
MY SECOND LINE
< /td >

there is no result with : '\n' and what i got : MY FIRST LINEMY SECOND LINE
i tried the "< br / >" and what i got : MY FIRST LINE < br / >MY SECOND LINE

\n is a waste of time in a website. If the br tag is shown then it's being escaped.

How I can upload doc files in ASP.Net and later retieve it using Gridview control.please specify complete code along with necessary table to be built in SQL Server 2005 Express Edition

Dream on, buddy, we're not here to do your work for you.

If you don't want to display the contents of the doc file, it's pretty trivial. You use an upload control, which is the only way to upload a file, then you store it as a blob with an id in the database. Then you make your download URL pass the id, get the blob from the DB and send it to the user.

Hi, I am getting the following error by reading the data from CSV file to dataset.
