Re: custom validator problem

Pretty easy, all you need to do is first split up the string of numbers:

string myNumberString = "2,3,6";<br />
string[] myNumbers = myNumberString.Split(',');

then just loop over them setting that item in the checkboixlist to Selected

int index;
for(string myNumber in myNumbers)
{
 if(int.TryParse(myNumber,out index))
 {
   myCheckBoxList.Items[index].Selected = true;
 }
}

Use the String.Spilit() method to change the string into One-Dimensional Array. Then iterate through the each Item of the CheckBoxList and check whether any Value in the string array matches with the Value of the ListItem. If yes mark that particular Item in the checkBoxList as selected/Checked.

string Value = "A,B,C";
ListItem lstItem = new ListItem(); 
string[] strArray = Value.Split(","); 
foreach ( lstItem in chklstItem.Items){  
  for (Int16 I = 0; I <= strArray.Length - 1; I++){  
     if (strArray(I) == lstItem.Value) { 
       lstItem.Selected = true;
     }
  }
}

"OnServerValidate" mean the validation has to go to server and came back to client.. so, the Postback will be occured... If you don't want postback, you can use "ClientValidationFunction" of Custom Validator.... Of course, that function should be written in clientscript...

Use the onclick method of the anchor tag to call javascript which redirects if appropriate. Set the href to #.

The situation is , i have a gridview that contains one rows ,
1.for hyperlink - for each row it has information for ten records , if the information pertaining to ten records are there in the database , then on clicking the hyperlink it shows the details of ten records , currently it shows what ever is there in database, i mean there may be 2 or 3 records information.
so that's y i want to restrict the user to first fill the complete information for ten records , only then u can view.
so i can either pop up a message box or i can make the hyperlink enable or disable.
in bothe the cases , i need to access the databas eto check the no of entries.
so what should i do?

You can make a hyperlink disabled by setting the href to # or an empty string. You can control it better by using onclick, then it can be dynamic.

You should get your info from the database when your grid is databound, and generate hyperlinks only if they are required. If you want it to update while the user is viewing the page, then you need to use AJAX, but I'd say that's overkill.

Yes, but in your case you would ask where each and every block would need to be placed, rather than building on previous knowledge gained in laying out the base.

So, yes, I like your analogy.

Hi,
I have a function in javascript which is called on 'onload ' event of the body. This function, takes the values from windows.dialogArguments and assigns it to textbox1.text. After this assignment, I want to call a server side function. But my problem is that, the server side function gets executed first before javascript function gets executed. How can I make it sequential?

Here's the situation with example:

javascript function
function LoadFunc()
{
var val=window.dialogArguments;
document.form1.txtMessage.value=val;
<%databind()%> -- server side function.

}

This function is called on 'onload' event of the body tag. But the problem is databind() gets executed first!

Any help is greatly appreciated....
Thanks,

I would look into PageMethods, its an ajax thing which allows you to call server side code from javascript.

Is it an ASP.NET AJAX thing ? AJAX itself doesn't have anything like that AFAIK.

Sorry, should have mentioned that its part of the ASP.net AJAX framework, i am not sure if its included in any others.

Debug the application, put breakpoints and check what value you are getting.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Here you are replacing the text of the selected item. Is that really what you intended, or are you just trying to remove the selection?

What are you trying to say? The only information that I managed to get from that is that there is some difference between the first and second time you run the code...

Experience is the sum of all the mistakes you have done.
