Seems like the DataSource has empty data. Are you sure that your DataTable has rows because I don't see any piece of code which is loading the DataTable with data.
In a DataGrid, if the DataSource is empty, the DataGrid will not show up. Use GridView control with has EmptyRowTemplate which will automatically show up if the DataSource doesn't has values.

You are Deleting file using DOS Command.

An alert only has an ok button, so the window.alert method doesn't return anything.
If you want the option to cancel the operation, you use the window.confirm method instead.
Despite everything, the person most likely to be fooling you next is yourself.

Can any one help me with the javascript part
protected void Button1_Click(object sender, EventArgs e)
{
/* The code to send values to database*/
/* AFTER SUCCESSFUL SENDING OF VALUES A JAVASCRIPT ALERT CONFIRMATION WITH OK BUTTON WHEN USER CLICK OK REDIRECT TO HOME.ASPX PAGE */
}
thanks in advance.
|
|
|
|
|
In Page_Init(Object sender, EventArgs e) // just like page_Load
Button1.Attributes.Add("onclick", "return confirm('are you sure?')");
If user chooses yes than code will be executed in Button1_Click, otherwise the code is not executed.

My question is how i can upload a file which has size more than 4MB with the FileUplaod control of asp.net.
I can able to upload file less than 4MB but more than 4MB i can not upload. For that which type of changes i have to made in my code or property.

Add this to the web.config
<System.Web>
<httpRuntime maxRequestLength="10000" />
</System.Web>
The number “10000” is in Kilobytes so this would give u 10 MB. U can change it to any file size u want
Hope this would help
Best Regards
