Hi,

Yes it is possible to enter everything you like in a textbox. I guess you want to evaluate the equation afterwards. Have a look at this article, this could be a good starting point:

Hi,

I need to clear all the Control field's - (Radiobuttonlist, Dropdownlist, Textboxes and Fileupload) values on a button click. I am able to do for Radiobuttonlist, Dropdownlist and Textboxes but not able to do for FileUpload control. Can anyone please help me out in this. Thanks in advance

txtAppID.Text = string.Empty;
txtkeywords.Text = string.Empty;
MtxtDesc.Text = string.Empty;
ddl_Domain.SelectedIndex = 0;
ddl_Theme.SelectedIndex = 0;
rbl_Businessarea.ClearSelection();
rbl_Clientsize.ClearSelection();

This is code i have written on a button click. On the same button click i need to clear the ASP:FileUpload control values too.

Thanks,
Santa.

Pardon me, you are Right. Now Before you Upload , you need to check if there is a File like this

if (FileUpload1.HasFile)
{


}

what you can do is that when you done Uploading you can clear it at the Upda of Uploading process like this

if (FileUpload1.HasFile)
     {
      //Do the Uploading
      //When done Clear the Upload control
       FileUpload1.HasFile = false;
     }

or you can do it like this

or you can do it with javascript like this

<script language="javascript">

    function ClearFileUpload()

    {

    var fil = document.getElementById("FileUpload1");

   fil.select();

   n=fil.createTextRange();

   n.execCommand('delete');

   fil.focus();

    }

    </script>

 

<asp:FileUpload ID="FileUpload1" runat="server" />

<asp:Button ID="Button1" runat="server" OnClientClick="ClearFileUpload()" Text="Clear" />

The Javascript function works fine.

the FileUpload.Hasfile = False does not work it errors out saying Property or indexer 'System.Web.UI.WebControls.FileUpload.HasFile' cannot be assigned to -- it is read only

So i used the javascript function. There is one more issue. When i use the Javascript function i am calling this methos on the OnClick of a Button, on the same OnClick event i have to clear the other fields for which the code id on the .cs file.

protected void btnClear_Click(object sender, EventArgs e)
{
txtAppID.Text = string.Empty;
txtkeywords.Text = string.Empty;
MtxtDesc.Text = string.Empty;
ddl_Domain.SelectedIndex = 0;
ddl_Theme.SelectedIndex = 0;
rbl_Businessarea.ClearSelection();
rbl_Clientsize.ClearSelection();
}
If both the functionalities are in .cs file can call it one after the other.
One functionality is in aspx page the other is in .cs file. So what do now.

Thanks,
Santa

I would rather move this to client side. Its always nice (atleast my preference) to handle the validations, field clearing at the client side itself.

Problem - Gridview databound column's value has a Decimal value consisting decimal point which has been converted to comma when using culture id-ID

G Nathan14-Sep-09 23:32

Hi friends

I have a problem of showing gridview's databound column value which binds decimal values. Actually it shows comma instead of showing decimal point in the decimal value.

For eg 20,02 instead of 20.02

My website s a multilingual website. if I select a english then it displays 20.02 in the BoundField column else it shows 20,02.

Could u guide me how to resolve this issue

My friend, I think this is OK. There are many cultures like French, Dutch etc where decimal is represented by a comma.

Hi,

same question again? To pass "a lot of parameter" you could use lists, arrays etc. It is also possible to write each parameter for itself. There is no "real" limit for parameters...

Again: Please tell us your exact problem, exception, error message etc.

This should help:

List<ListItem> LlstSelectedItems = new List<ListItem>();
		for(int LiCount = 0; LiCount < ListBox1.Items.Count; LiCount++)
		{
			if (ListBox1.Items[LiCount].Selected)
				LlstSelectedItems.Add(ListBox1.Items[LiCount]);
