Assume that you put a list box. use the following method to form the string to be inserted to DB

string strInsertValue = string.Empty;
for(int i=0;i<=ListBoxCount-1;i++)
{
    IfListItemSelected
        strInsertValue = ListBoxSelectedValue + ",";
}

at the time of retrieving data from DB split the data with ','. You will get a string array and do the processing with that.

I think that navaneeth's reply is to put all the items in a single row of a column, not what you were looking for.

Where do you get a problem with several inserts depending on the data selected? You just need some kind of loop.

His requirement was for single column of a row, not the other way around. Of course i may be misreading what he actually wants...

yeah you are right paddy

paddy i guess tats wat i want.......
let me explain.....
the requirement is once the user selects multiple items from the list box,
and submits the form, all the selected values should be inserted into a particular column of the table i,e suppose the listbox has a list if languages say, then all the selected languages from the listbox, should be inserted into the column called "languages", (seperated by comma) of a row in the table.

do you have a solution for this???

Hi,

The following is the code you can use to get comma separated string of selected Items from the listbox.

string strSelected = "";
foreach ( ListItem lstItem in lstBox.Items )
{
if ( lstItem.Selected )
{
strSelected += lstItem.Value + ",";
}
}

put "strSelected" in to your insert query and you are done.

Thanks and Regards,

hey Chetan,
wat should i set to ensure that a maximum of only 3 items could be selected from a list box???
is there any property for that or some other code???
please send me the details

Chetan Ranpariya27-May-07 19:18

Hi,

There is no such property which you can set get your required functionality.
But you can apply your logic in code behind or in javascript to check how many items are selected.
In code behind you can use GetSelectedIndices() of listbox which will return an array of all the indices of selected items in the listbox.

you can check for the length of that array if it is less than 3.
int[] selectedindices = lstBox.GetSelectedIndices();
string strSelected = "";
if(selectedindices.Length<=3)
{
foreach(int i in selectedindices)
{
strSelected += lstBox.Items[i].Value + ",";
}
}

use strSelected in the Insert query.

I hope this will help you.

Thanks and Regards,

Hi,

The AutoPostBack property of your listbox should be set to false if you dont want any server code to be executed when u select an item from the listbox.

So set AutoPostBack property to false for your listbox and it is done.

Hi Chetan,
I have another requirement.
I need the code for uploading files into the database.
I tried using the FileUpload control in ASP.NET 2.0, and got the code(to be put in the button click event code) to upload the files in my own system in some other location.
However, my requirement is that i should be able to upload the file into a remote system or the SQL database.
Please give me the code for this....

Thank You.

//The following line of code specifies the path

Hi,

You just need to provide the server path to the SaveAs Function

FileUpload1.SaveAs("http:\\servername\\foldername\\" + filename;

where filename is the name of file you want to upload.

Thanks and Regards,

Hi Chetan,
I have an issue!!!

I have a dropdown list(somewhere near the bottom) in my page with autopostback set on.
The problem is as soon as i select an item from the list, due to auto postback,the control goes to the top of the page!(the page is long enough, so the user has to scroll down to completely fill the form).
so the user has to again scroll down till bottom of the page.

Hi,

If you r working on .net 2.0 then you should put MaintainScrollPositionOnPostback="true" in Page directive of your page.

and if u r working on .net 1.1 then you should put SmartNavigation = "true" in page directive of your page.

Thanks and Regards,
