You only fill DataValueField but you should also fill DataTextField.

In the OnSelectedIndexChanged- event you can then pick the .SelectedValue, which is the DataValueField.. If you pick in that event the .SelectedIndex.Text you have the DataTextField.

In this case you can show a database description field in the DataTextField while attaching it's databse field ID to the DataValueField.

OK thanks for that
Now say Ive got 3 rows I want to add 1,2,3 to each dropdown in each row therefore I want the number of rows to appear in the dropdownlist, how would I do that? WOuld it just be an extension to the code I have?

the extension would be like this.

DropDownList dropdown = new DropDownList();
foreach (GridViewRow row in GridView1.Rows)
{
   try
   {
      dropdown = ((DropDownList)row.FindControl("ddorder"));
      for (int count = 1; count <= 3; count++)
      {
           dropdown.Items.Add(new ListItem(count.ToString(),count.ToString()));
      }
   }
   catch (Exception err)
   {
      /// Do Someting with err.Message;
   }
}

OK, final question

How do I select the correct row dropdownlist when updating my database.
At the moment when I set it to dropdown.selecteditemvalue it takes the very last row value instead of the current one.
How would I fix this?
thanks for your great help so far! Smile | :)

also how do I get another column value from the same row?

DropDown.SelectedValue I guess you mean

You know you hav to run along each GridViewRow to see the value of the dropdown control?

Like i showed you
Int32 selectRow = 0;
foreach (GridViewRow row in GridView1.Rows)
{
GridView1.SelectedIndex = selectRow;
// find you dropdownControl
//row.SelectedValue will show now values
selectRow++;
}

There is no reason to set the text and the value to the same value. A ListItem without a value returns the text property as value.

dropdown.Items.Add(new ListItem(count.ToString()));

Despite everything, the person most likely to be fooling you next is yourself.

I did not know this. Thanks for the tip

Well....If you want to add an item to the DropDownList you could do
dropdown.Items.Add(new ListItem(count.ToString(),count.ToString()));

in stead of dropdown.DataValueField = count.ToString();
dropdown.DataTextField = count.ToString();

DataxxxxField is used for DataBinding for values retrieved from a database

In page_Load remember to place code in
if (!Page.IsPostBack)
{
// the code
}

I would try this

protected void CheckLogin()
{
   if (Session["LoginAdminUser"] == null)
   {
       Response.Redirect("~/admin/oola_log_in.aspx");
   } 
   else 
   {
       LoginUser= Session["oLoginAdminUser"].ToString();   }
}

LoginUser = Type String
Session["oLoginAdminUser"] = Type Object so you need the ToString() addition

VBA.Calendar = vbCalHijri

Hello everybody,

I am facing a problem. I am trying to upload a file using Pure ASP and I am not using any component. On development server it is allowing upto 10MB to upload but on production server it is not taking more than 1KB. If I try to upload more than 1KB file "Internal Server Error" page is getting displayed.

Thanks

Thanks for the reply but it is not ASP.NET application rather it is Pure/Classic ASP application.

Do you want to update all gridview data on button click event?
or
Do you want to update only one row on Droddown selected index change event?

I just need to update the row that I am currently on.
I want to update just the value I have chosen from the dropdownlist but I need to match it to the correct ID for that row. hope that makes sense
Also how can I find the dropdownlist for the current row.
I have:

DropDownList dd = ((DropDownList)row2.FindControl("ddorder")); but its showing object reference error
That code above is on my selectecchange event for the dropdownlist

thanks so far!!! Smile | :)

If you want to update single row on dopdown selected index change event then first find out dropdownlist on rowCreatedEvent of gridview and create event handler of selected index changed.

.netman wrote:

Look at here
On rowCreatedEvent of Gridview

if(e.Row.Rowtype==DataControlRowType.DataRow)
{
   DropDownList ddl=(DropDownList)e.Row.FindControl("DropDownListID")
   ddl.ToolTip=CurrentID; 
   //Get CurrentID of currentROw and set DropDownList ToolTip
   //Now create event Handler of DropDownList
}

On SelectedIndexChangeEvent,You have two argument e as eventArgs and Sender as an object
cast object to dropdownlist and get selectedValue and update data

for Example

DropDownList ddl=(DropDownList)sender;
string selectedValue=ddl.SelectedValue; //or ddl.SelectedText
string ID=ddl.ToolTip; //get ID and you can update your database value using this ID

Sorry it is RowType not Rowtype.
c# is case sensitive

if(e.Row.RowType==DataControlRowType.DataRow)
