You may also need to set the selected indexes from session after the ddls are databound.

How can I do that? Can you provide me some code examples?

Thanks, I think I almost figured it out.. except the dropdownlist3 is still set back to the default value ( doesn't remember previous selected value). Is it because the dropdownbox3 is populated by the drop down box4 ( cascading dropdown box)? How can I work around this?
--Here is the code for dropdownbox3
<asp:dropdownlist id="DropDownList3" runat="server" datasourceid="SqlDataSource4" datatextfield="unitname_abbr" datavaluefield="unit_abbr" width="352px" font-names="Tahoma" font-size="8pt" onselectedindexchanged="DropDownList3_SelectedIndexChanged" autopostback="True">
<asp:sqldatasource id="SqlDataSource4" runat="server" connectionstring="<%$ ConnectionStrings:Finance_AppsConnectionString %>" selectcommand="
select distinct(unit_name) as unit_name,unit_abbr
, ( convert(varchar(5), unit_abbr) + ' - ' + convert(varchar(50), unit_name))as unitname_abbr
from revenue_aggregate
where region_num = @region_num
group by unit_name, unit_abbr
order by unit_abbr">
<selectparameters>
<asp:controlparameter controlid="DropDownList4" name="region_num" propertyname="SelectedValue">
--------------------------------------------------Updted code
if (!Page.IsPostBack)
{
try
{
this.DropDownList1.SelectedIndex = Convert.ToInt32(this.Session["MMselectedvalue"]);
this.DropDownList2.SelectedIndex = Convert.ToInt32(this.Session["YYselectedvalue"]);
this.DropDownList3.SelectedIndex = Convert.ToInt32(this.Session["Unitselectedvalue"]);
this.DropDownList4.SelectedIndex = Convert.ToInt32(this.Session["Regionselectedvalue"]);
}
catch
{
}
}
else
{
}

Hi.
I have DataGrid that has 11 columns. Some of the columns are white and some are gray. How can I change row color onmouseover and when put the original color back? I've tried to use in the
ItemDataBound the following
e.Item.Attributes.Add("onmouseover", "changeMouseOverandOut(this, false)")
and in the JavaScript
var lastColorUsed;
function changeMouseOverandOut(row, highlight){
if(!highlight) {
lastColorUsed = row.style.backgroundColor;
row.style.backgroundColor = '#FFFF66';
}
else
row.style.backgroundColor = lastColorUsed;
}
It does work but only for white background. My gray background color doesn't change. Setting background color from ItemDataBound gives the same result so that's why I used JavaScript function (it is nice to try new things).
Please hlep.

Hi AlexFromTo 
Here is a codesample that shows how you can get the desired result for a cell, you can probably modify the code to change a row instead.

Hello,
I am creating a web site using ASP.Net using C#. I want customers to buy products from the website. What is the best and most secure way to use different payment methods. The website will need to be able to use credit cards, and another payment method, e.g. paypay. What is the best way to implement these into a ASP.Net website?
Thanks in advance,
Steve

Hello,
we are using Master Pages in asp.net 2.0. Our Master page has three contentplaceholders. On the left most ContentPlaceHolder we have all the links for the navigation of the site. One of the links on it is "Admin" link. Now, if some one with "Admin" Role logs in and clicks on it then the "Admin" link should populate all the other links underneath the "Admin" link. I am looking for some thing like toggel link.
Can some one please help me how do I accomplish this toggle link type of task.
Thanks

I am trying to determine if a file is a jpeg
I know I should use the System.Drawing.Imaging.Image class.
And I can see the enumeration to show me what type.
But I can't find a property or method to extract that information.
Please, no answers telling me to check the extension in the file name.
Thanks for helping me.
Thanks,
Nick
1 line of code equals many bugs. So don't write any!!

Assuming that this is an uploaded file from the client - can you check the mime type?
|
|
|
|
|
nah. I want to check the file internally. I only want jpeg avatars so I need to make sure the file is a jpeg. I caught one user changing the extension name to fool me.
Thanks tho.

You can read the first few bytes of the file and see if it contains a valid JPEG header.
---
b { font-weight: normal; }
|
|
|
|
|
Yeah, I could. But I want the framework to tell me what it is.
I think hacking into the file, while valid, isn't the solution I was looking for.
Thanks for helping tho.

If the file can be loaded into a Bitmap object, then you can use this test to see if it is a JPEG/JPG type image:
if( someBitmap.RawFormat.Guid == System.Drawing.Imaging.ImageFormat.Jpeg.Guid ) {}

I have a popup datepicker in my application which is ran using javascript. When I run my application from my pc it works fine but wehen I run my app from a server it causes a problem. The problem is that if I select a date like today 02/05/2006 this will go into the field on my app, when I submit the form in the date goes into the datbase field as 05/02/2006 which is the wrong way round. I am using GMT as the time zone regional setting. The field in the database is datetime.
Anyone any ideas why this is happening?

Simple. Its getting converted to the american format of storing dates. The solution is very simple. Just before writing to the Database, make sure that you pass it as a DateTime variable using some syntax like,
DateTime dt=DateTime.Parse(dtPicker.SelectedDate.ToString("dd-MM-yyyy");
Hence even if a value such as 02/05/2006 is stored in the database as 05/02/2006, while retrieving it will still get you 02/05/2006 once you get it with the same format as dt.ToString("dd-MM-yyyy");
|

It is being passed into the stored procedure in the British format, so I think I need to do the conversion you are proposing in the datbase itself. Can I use your code "DateTime dt=DateTime.Parse(dtPicker.SelectedDate.ToString("dd-MM-yyyy");" in the stored procedure?
I need it stored in the dataase in the correct format as I run some other queries based on the dates i.e. select all between two dates.
