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

In your form load event you can check the IsPostBack variable. It is set to true when the page posts back to the web server. Each individual button probably should have it's own onClick event in your code behind.

Text_changed event

Hi..

I have a textbox that was firing Text_changed event when the user press Enter.but now it is not firing any more.But the handler for this event is executed when a postback occur(for example when I click a button).

The only change I made it was putting the asp:textbox in a <DIV> instead of a <table><tr><td>.
I observed when I press enter in the textbox I hear a sound(one of the windows usual sounds).

Could any one tell me how to solve this problem and make it working as before(when the user press Enter)?

I am too late but i will never give up

If you set the autopostback to true on the textbox it will postback when the text changes. I don't think you really want to do this, since it takes time for the web page to reload for each key press. You probably want to use some javascript for you text change event.

Hi..

It was working without autopostback.and the event was only fired when the user press Enter not any other key press.

I am too late but i will never give up

If it used to work it was by error. The enter key was probably causing a button to get pressed, since that what it does on the web. I would guess a one point that button didn't have any code in your code behind so you didn't notice it. What you are trying to do doesn't work.

Sorry but I don't think so because the textbox have the access(which change using TAB).

May you explain to me what do you mean by:
'since that what it does on the web.'

Please explain to me your idea because this is the only problem remain to me to upload updates to my old website.

I am too late but i will never give up

The only way in .net to do a postback is 1) to have a button 2) set the control to autopost back. I wrote an article about catching the enter key to press the correct button on the form.

I need help, I am trying to print results loaded into a Datalist and I have not been able to make any headway. The datalist is loaded from a query and has the option of displaying detailed info or summary. I would like to print out (which ever is selected) the results as they are in the datalist.

I am new to this work and need some assistance.

Reading a Textbox into an array

4-May-07 9:01

Have a look at this article[^]

I have a textbox, that records the file names of upload files, and seperates it out with a , I would like to create an array that would read this text box, and seperate it out, so I can create a link for each file. I could really use some examples in code. My codebehind is C#

Tarakeshwar Reddy4-May-07 8:15

4-May-07 8:15

string[] FileNames = txtFileNames.Text.Split(',');

Ibuprofen4-May-07 8:17

4-May-07 8:17

So then it will string as them as? like how do I assign each portion of the string a varible? Or am I not getting something as simple? Trying to figure out how I would link them.

Ibuprofen4-May-07 8:38

4-May-07 8:38

Something like this no?

string FileNames[1]=dr["HyperLink1"].ToString();

Tarakeshwar Reddy4-May-07 8:46

Put a placeholder control in the screen, read the filenames and dynamically add link buttons and the click event for each of the links.

Re: Reading a Textbox into an array [modified]

4-May-07 8:48

If I understood any of this, I imagine I'd be in good shape. Pardon me, I've only been using .net for about 3 months before, that had never developed anything, and was given a full blown, huge ass project by my work, they know I can't code C# and I am still learning, they just elinated my job... I hate to be a pain in the ass, but could you explain a little further?

Tarakeshwar Reddy4-May-07 9:24

Have a look at this article[^] on codeproject, it shows you how to create dynamic controls. This msdn[^] shows you how to add controls to a place holder.

In the click event of the button, split the filenames into an array, for every item in the array create a linkbutton with a click event and add it to the placeholder

ex: 
LinkButton link;
for(int i  = 0; i <= FileNames.Length-1 ; i++)
{
	link = new LinkButton();
	link.ID = "link"+i.ToString();
	link.Text = "http://www.yoursite.com/uploadedfile/"+ FileNames[i];
	link.Click += new EventHandler(link_Click);
	PlaceHolder1.Controls.Add(link);
}

Instead of the linkbutton you can also use the label control and set the text of the label control as Label1.Text = a href to pass the location to it.

This is just a sample code, just change it to how you need it. You will have to ensure that the controls get added back when a postback takes place.
