You will need to loop through all the cells and then set there property. You can also place a transparent div over the panel so that controls beneath will be visible but not accessible (something like what happens in case of pop up).

You want to do it on the SQL query or in your C# code?

C# code - Split the text on "/" and get the max and min values from the resultant array.

SQL query - select left(ColName, charindex('/', ColName)-1), right(ColName, len(ColName)-charindex('/', ColName))

You will need to test and correct the SQL as necessary.

Try this

SELECT 
'maximum valuue='+(SUBSTRING(valstr,1,CHARINDEX('/',valstr)-1 )),
'minimum valuue='+SUBSTRING(valstr,CHARINDEX('/',valstr)+1 ,LEN(valstr))

FROM mytable2

As far as I know, there is no conventional method to do so.
Even if you achieve it somehow, it is useless unless you process data entered at client's browser.
"Eval()" function is the only thing I can consider which might be needed at server side from JavaScript.

BTW, Why do you want to do so?
Just call your JavaScript function in client side, Post the result back to the server,
then you can access the result at the server. After wards, you can process on the result there.

Custom Validator for DataGrid Template Column

10-Dec-09 19:38

Am I correct in saying that you need to execute a javascript function after a particular event has been completed and the server has rendered the resultant page to the client?

If this is what you need then, just use the RegisterStartupScript method in the Page / ClientScript object, based on your version on ASP.NET, to place a call to the javascript function.

This call would be executed once the browser receives the markup

Hi,

User server side script to do this

Hi,

I have a DataGrid that has a textbox within a template column that will populate a SQL DB.

The user can click on the edit button(s) to modify 3 different types of data in this column:

Account No
FirstName, LastName
Email Address

I have a custom validator that does server validation but I cannot work out (I am new to this) how to validate the 3 different types of data using a regular expression.

Although the validator correctly highlights the textboxes that do not match a single regex I would like to have a different regex for each textbox row within the grid. Is there any way I can do that. I have included the relevant bits of code below.

Thanks!

Graham

For using Custom Validator and Regex

Graham Baxter wrote:
args.IsValid = false

It Wont Stop the execution it will go the the Next event..!
But You can check the Event in the Button click I also got this problem .
I overcome it by Checking the args value in button click..!

But For You Case You have to go for client side validation..!
Here is the sample code i used for Custom Validation

protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
{
    try
    {
        int timetmp = Convert.ToInt32(EmailSettings.ReserErrorTime);
        int time1 = timetmp + 15;
        DateTime current = System.DateTime.Now.AddMinutes(time1).ToUniversalTime ();

        if (txtReservationdate.Text != "")
        {
            string Date11 = ReserExactTime.Value;
            string date12 = Date11.Substring(4, 21);
            DateTime resertime = Convert.ToDateTime(date12);

            if (resertime > current)
            {
                temp = true;
            }
            else
            {
                temp = false;

            }
        }
        else
        {

            string Date11 = ReserExactTime.Value;
            string date12 = Date11.Substring(4, 21);
            DateTime resertime = Convert.ToDateTime(date12);
            if (resertime > current)
            {
                temp = true;
            }
            else
            {
                temp = false;

            }
        }

    }
    catch (Exception ie)
    {
        logger.Error("ReserDate :-" + ie.Message, ie);
    }
}

and i check it button click of the temp value..!

try this link for regex..!

The args.value that the validator sends back is 1 long string of the text in all 3 of the the textboxes (i.e. 112233JohnSmithjs@email.com) so I was trying to work out out to pick each textbox field out and validate it. However, based on the regex the validator does identify which textbox has incorrect data in it...

Thanks

Dinesh Mani10-Dec-09 18:58

Any specific reason why you wish to have only one regular expression/only one validator? How about having 3 separate validators for the 3 controls?

I'm not sure, but check if the sender object contains the control that raised the validation. i.e. check if sender can be used to identify the which text box you are validating and then use a switch case and use 3 different regex to validate the data.

HTH

Graham Baxter11-Dec-09 1:41

I don't mind having 3 validators but I do not know how to assign them to the textbox values within the datagrid as it has only '1' id. Can you give me a pointer on how to do that?

Thanks

Graham

Dinesh Mani11-Dec-09 2:13

11-Dec-09 2:13

I'm very sorry for not reading through the code earlier. Now, based on the code that you have submitted, it looks like all the data is thrown together in the same text box - txtParamData. So, the validator gets just one data like this - 112233JohnSmithjs@email.com

Now to validate this with one regex is not going to be easy, unless the data is of common length or there would be some separator between the data items. Is the above sample a valid data or just some text? Is there anyway that you can enforce a rule on the user to use some separator between the data items? Can you not change the design to display the data items in separate text boxes?

Insert image with html editor

11-Dec-09 2:20

There are actually 3 textboxes (contained within that one textbox id) in the datagrid and the user enters the data into each one seperately. The problem is the different data (account/name/email) is in different rows but the same column so I cannot find an easy way to validate them in that grid configuration.

Thanks

I've been looking for a free WYSIWYG html editor to add into my asp project. One thing I have found odd is that ALL of the editors, (including the high dollar ones) only insert a 20x20 place holder for the image instead of uploading the image.

What is up with this? Why is this feature even shown if the user can't actually upload the image?

Well, actually the image is uploaded to a temporary folder in the server before showing it in the htmlbox. There is no way to show an image directly from client, without uploading it to the server.

Now your duty is to find the temporary folder and move them to your location when the code uploads. Wink | ;)

Hi! I have a global variable which is initialized in Global.asax (in the Session_start event). Now I want using Javascript to update this variable and I don't know how to do that. Why I have to do that? Because I used javascript to create a small timer which, at every 10 minutes I want to increase the variable by 1. Can anyone help me please?

Hi Munteanu,

Create a page or a web service to increase your value. Use AJAX request to call the page/web service. For the web service you can use generated proxy javascript classes to call it. For the page you can use for example jquery to call it. http://docs.jquery.com/Ajax

Hi,

just create ASP.NET page. On page_load increment your value.

public partial class my_page : System.Web.UI.Page {

        protected void Page_Load(object sender, EventArgs e) {
            // increment your value
        }
    }

from the JavaScript call your page:

$.get('my_page.aspx');
