plz told me that you design this for web or desktop application.
if you are using web application tht page then you are rally doing wrong to save data without clicking button bcz in web every thing take place remotly on your sever that page request to server,while in desktop application this can be affordable,any how.
i am going to tell you method for both web and desktop application.
on text box lost focus save the data to globally declare variable in desktop application and web application use viewstate to save the first text box data.now if the user go to the next text box then on the lost focus of that text save to db both,otherwise if user close the form or come again to the first textbox save to db and clear the first textbox.
try this if any problem ask for help.
thanx

Where did you add the combo boxes to the Controls collection?
you must add them first in order to find them later.
|
|
|
|

i add these comboboxes to diferent dynamic created tables then add these tables to a place holder.you can see different findcontrol function in post i given.
i try following
placeholdername.findcontrol()
tablenames.findcontrol()
but fail.
i done radio button finding on similar technique that working properly but with drop down it not working.

Hi,
Put your C# application in the wwwroot/Project folder, and use a an anchor tag.
Example:
in code behind, in the page_load (or another appropriate event) give the path of your C# application.
give the file path to the href property of the anchor control. I hope it will work.

I am new to .net and having some difficulties in debugging unmanaged Native DLL in .net..
I am using a Native COM DLL in ASP.Net web application. The problem is I am unable to degul my DLL in .NET. When I add a reference to DLL a interop DLL is created and when I try to load Symbol information manually I am unable to do so.
How can I Debug com DLL here ???
Please Help?

In your application is there already the DLL is referenced pls check it out.
If the Dll is already referenced delete that one and try to reference the New Dll it will work fine.

I have to validate my web page using java script. I have one dropdown list also . I need a javascript to validate weather any item in dropdownlist is selected or not. e.g ddlDrop is my dropdownlist.
To validate other controls I am using following
function validate()
{
if (document.getElementById("<%=txtUserName.ClientID%>").value=="")
{
alert("Please Pprovide UserName");
document.getElementById("<%=txtUserName.ClientID%>").focus();
return false;
}
if (document.getElementById("<%=txtPassword.ClientID%>").value=="")
{
alert("Please provide Password");
document.getElementById("<%=txtPassword.ClientID%>").focus();
return false;
}
seema

you should not use <%=field.client%> insteadyou should use the field name that you have in html page (page.aspx) . you can validate the dropdownlists in two ways:
1. using .value == '' (same way you are validatiing the other fields)
2. using selectedIndex == 0 (provided the first value is dummy e.g. Select One)
and you can access the form field names in two ways:
1. using document.getElementById('fieldname')
2. using form name document.formname.fieldname

Try This-:
function Check()
{
if(document.getElementById("<%=ddlDrop.clientID%>").value=="(Select One)")
{
alert('Please select a ddlDrop');
document.getElementById("<%=ddlDrop.clientID%>").focus();
return false;
}
}
Then call this Javascript on Page Load
btn.Attributes.Add("onclick", "return Check();")
If you have any Queries Please ask

you have to check the date before displaying on the page, you can do it in sql statement or on rowdatabound, in sql, you can do,
case when datefield='1/1/1900' then '' else convert(varchar, datefield, 101) end as datefield
in rowdatabound
if(row.Cells[datefieldindex].Text=='1/1/1900')
row.Cells[datefieldindex].Text = string.Empty;

Thx for ur help but i didn't know how to solve it  , i am a new developer and i have a little experience. Lets say i want to use the rowdatabound, but what is that a property of the Gridview??
I am using a GridView to display the data and one of its columns displayes the time "with the date that i don't want it to appear". where should i put the code that u sent????
Thanx for ur help

well the following code should be used in your SQL STATEMENT or stored procedure whateevr you are using
case when datefield='1/1/1900' then '' else convert(varchar, datefield, 101) end as datefield
or use OnRowDataBound="gv_RowDataBound" in html where you insert the gridview control and int he code behind create a sub
protected virtual void gv_RowDataBound(object source, gridviewroweventargs e)
and use this in this sub
if(row.Cells[datefieldindex].Text=='1/1/1900')
row.Cells[datefieldindex].Text = string.Empty;
look at this [^] for gridview
