One of the php files has the following lines of code. I don't know what path I should put in here '$rss->cache_dir = ? '. I've copied in the instructions below.

header('Content-type: text/xml');

// include lastRSS
include "lastRSS.php"; //path to lastRSS.php on your server from this script ("bridge.php")

// Create lastRSS object
$rss = new lastRSS;

$rss->cache_dir = 'cache'; //path to cache directory on your server from this script. Chmod 777!

$rss->date_format = 'M d, Y g:i:s A'; //date format of RSS item. See PHP date() function for possible input.

Yeah this is a fairly well known bug in IE. Root cause is that IE uses lightweight controls, except for drop down lists, which always render on top.

You can get around this by sticking an empty iframe in the item that pops up, width and height 100% but given a z-order to make it at the bottom. This works because the iframe ends up being rendered after the drop down list, forcing all the controls that are higher than the iframe to the top.

Bit dodgy though, and I've never really liked it. The other option I've seen uses js to hide the drop down lists when the calendar / menu pops up. :/

Hello All,

I am having a webform with two textbox and and one dropdownlist .. and one gridview

when i entered values in textbox and select dropdownlist value after that i click on save button then it will save in database.

and the display the textbox value and dropdownlist selected value in GridView what i taken in the same page .

The following code i wrote for in codebehind:

protected void Save_Click(object sender, EventArgs e)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Mfund_String"].ConnectionString))
{
con.Open();
SqlCommand cmd = new SqlCommand("insert into mfund_share_dtls values(" + this.TextBox1.Text + ",'" + this.ddlFund_name.SelectedItem.Value + "','" + this.ddlDOBdd.SelectedItem.Value + '-' + this.ddlDOBmm.SelectedItem.Value + '-' + this.ddlDOByyyy.SelectedItem.Value + "'," + this.txtNoUnits.Text + "," + this.txtPricePaid.Text + ")", con);
cmd.ExecuteNonQuery();

SqlCommand cmd1 = new SqlCommand("SELECT fund_no, usr_no, fund_name, dop, no_units, price_paid FROM mfund_share_dtls WHERE(usr_no = " + this.TextBox1.Text + ") AND (fund_no =(SELECT MAX(fund_no) AS Expr1 FROM mfund_share_dtls AS mfund_share_dtls_1 WHERE(usr_no = " + this.TextBox1.Text + ")))", con);

SqlDataReader dbdr = cmd1.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(dbdr);
dbdr.Close();
GridView1.DataSource = dt;
GridView1.DataBind();
}

}

So now i want in gridview edit... suppose the client mistakenly chosen wrong dropdownlist value and enterd wrong textbox value,

so now he want to edit the dropdownlist value and textbox value in gridview.

How i have to approach for gridview update through code behind and please guide me ...i need to display the dropdownlist also to select correct dropdownlist value in gridview update.

Many Thanks

Use Template Column in DataList control. Put the LinkControl in that template column.

OR

<a href="http://mysite/anotherpage.aspx?id=1" > <%# DataBinder.Eval(Container.DataItem,"fieldName") %></a>

Okay. Lets debug the application..

Let's say we have two pages called page1 and page2. We will divide the issue into small pieces ~
1. Using static data in page1
2. Retrieving the data in page2
3. Checking whether the SQL statment is correct or not
4. Changing static data to dynamic data in page1.

1. Using static data in page1

We will remove all dynamic value in A link to avoid NULL value and "".

Note: dynamic value means <%# DataBinder.Eval(Container.DataItem,"AD_TYPE") %>.

<a  href="http://localhost/approvedplotfinal/classified/page2.aspx?li=<%#DataBinder.Eval(Container.DataItem,"AD_TITLE") %>,type=<%# DataBinder.Eval(Container.DataItem,"AD_TYPE") %>,price=<%# DataBinder.Eval(Container.DataItem,"PRICE") %>"><br />
                        <%# DataBinder.Eval(Container.DataItem,"AD_TITLE") %><br />
</a><br />

We will replace all dynamic value with all static value.

<br />
<a  href="http://localhost/approvedplotfinal/classified/page2.aspx?li=mytitle&type=mytype&price=100" ><br />
     <%# DataBinder.Eval(Container.DataItem,"AD_TITLE") %><br />
                    </a>

Run the application to check whether there is any error or not.

2. Retrieving the data in page2

Forget about other code in page2. We will assume that we have only the following lines in Page Load.

search=Request.QueryString["li"].ToString();
type1=Request.QueryString["type"].ToString();
price=Request.QueryString["price"].ToString();

- Set the breakpoint at "search" variable.
- Run the application. (Page1 is start-up page)
- Click the link in page1. (it will take you to page2.)
- Check whether "Request.QueryString["li"]" is null or not.
- Check whether "Request.QueryString["type"]" is null or not.
- Check whether "Request.QueryString["price"]" is null or not.

Note: All three parameters should not be NULL. If you are getting NULL then let me know.

3. Checking whether the SQL statment is correct or not

Which Database are you using? If it's SQL Server, you don't need "&&".

string sstr="select * FROM ads where AD_TITLE='"+search+"'&& AD_TYPE='"+type1+"' && PRICE='"+price+"' ";<br />

So, we will change something like that.

string sstr="select * FROM ads where AD_TITLE='" + search + "' AND AD_TYPE = '" + type1 + "'     AND PRICE='"+ price + "'";<br />

- Check this variable "sstr" in Quick Watch or Immediate Window.
- Copy the string from Quick Watch or Immediate Window.
- Paste in Query Analyzer and Run it.
(You should not get any error. this is about checking whether the SQL statement is correct or not.)

4. Changing static data to dynamic data in page1.

It is still working fine. we will remove the static code in page and replace with dynamic code.
So, the following code will be used again..

<a  href="http://localhost/approvedplotfinal/classified/page2.aspx?li=<%#DataBinder.Eval(Container.DataItem,"AD_TITLE") %>,type=<%# DataBinder.Eval(Container.DataItem,"AD_TYPE") %>,price=<%# DataBinder.Eval(Container.DataItem,"PRICE") %>"><br />
                        <%# DataBinder.Eval(Container.DataItem,"AD_TITLE") %><br />
</a><br />

- Run the application
- Click the link in page1.
- Check the Request.QueryString and SQL Statement in page2.

if it's working until now, you are done.. Smile | :)

Please follow the step as I mention here.. let me know the result..

If you wanna do inserting, editing and deleting the record, I would suggest you to use "DataGrid" or "GridView" control instead of "DataList".

15-Aug-07 21:25

No. AFAIK, it's not possible to do that with File Upload control. maybe. you may look around flash or ActiveX control.. I'm sure that HTML file control doesn't have that feature. So, you will have to check the extension at code-behind.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
