Re: re-ordering a set of numbers automatically

No sorry
basically if they add a 2 to the following sequence
1,2,3,4,5,6

then every number including the exisiting 2 will increment by 1

basically the numbers are assigned to an item so lets say its like this

1 Itemid 1234
2 Itemid 1667
3 Itemid 1435
4 Itemid 1222
5 Itemid 1696
6 Itemid 1240

i added the following: number 2 Itemid 0987, the list would then become

1 Itemid 1234
2 Itemid 0987
3 Itemid 1667
4 Itemid 1435
5 Itemid 1222
6 Itemid 1696
7 Itemid 1240

I would prefer to keep a sequential order rather then just make one up

does this make more sense?

thanks

OK, I get it. You're changing the values you have, I can't think of any way to automate that, you'd need to work out where it was being inserted and change yuor values accordingly. I assume they are not primary keys coming from a database, as that would cause issues, obviously.

The name 'Menu1' does not exist in the current context

8-Apr-08 1:16

No they are not primary keys
One way would be to add 1 to every number that is in the table after the new number which has been entered, do you think this is feasable?
I would know what the new number entered would be so I could just match that to a number in the database and add 1 to the exisiting numeber and then to every number after that, phew!!
I know that every number in the list would be in order after that so that wouldn't be an issue.

I Copied the Menu1 Control form 1 form to another form because the other form contains the same coding and also some
additional coding for that form.

But it gives me above error.

The error message is clear enough. Isn't it ?

What makes you feel that the control does exist, when the error message tells you it doesn't ? What help do you expect from us when it's clear what the error message means and you've posted no code to try and prove that the error is wrong, or to help us point out why it's right ?

just like we give rights to a web form to according to user, i have to give rights to a web control in a web page(e.g visible or enable = true/false) according to user.

Example:

Admin can edit a textbox 'txt1' in a web page page1.
Jeo can just view a textbox 'txt1' on the same page.

I am creating a web page in which i will select a web page from DDL. All the control on selected should be shown, so that i can give rights to them.

Thanks for answering.

Your requirement seems to be odd. I don't think that you can have field level security as you told. Alternatively, you can implement a rule validation system to your business objects in the same way like CSLA does. Then add rules for different kinds of user, and when user trying to save the BO, throw error indicating the broken rules.

You should use the standard asp.net login control and then through the web configuration you can then asign rights to users.

If you dont want to do that use the following:
Put a column in your login table and call it permissions, then set the permissions as so:
User1 rights = 0
Admin rights = 1

then just check this value in your c# code e.g.

if (rights = 1)
{
txt1.enabled = true;
}
else
{
txt1.enabled = false;
}

something like that, remember what Ive written is half pesudo code so you just need to amend that

Problem in moving text from one textbox to another

8-Apr-08 0:11

Please don't ask variations of the same question over and over. Continue the discussion where it was started. If you want quicker answers, ask clearer questions to start with.

Your best bet is to build the lists yourself, not try to auto generate them.

I recommend you do some reading on ASP.NET. Basically, just because the IDE doesn't show you an event, doesn't mean it doesn't exist, it just doesn't exist on the server side. You can add an onblur to a textbox, and it will be passed to the client and work perfectly.

Your next problem is getting the cliend side Id of your textboxes. This is represented by the ClientID property of your server control. You need to write that to the client, either inline in your script, or as script that creates js variables you can use. Also never call document.getElementById and assume it returns something, add a step that checks it.

Problem with onrowcreate in gridview

What you want is impossible. A web app runs in the browser, and cannot enumerate processes on the local machine. Why would you want to do that ?

Hi
I have the following code:
When it runs I get the error:
<b>System.InvalidCastException: Specified cast is not valid.</b>

chkIgnore = a checkbox
Ignore = a field in a database type nvarchar size 1, can either have Y or N in the column

If anyone can help that would be great, bit stuck on this one.

thanks! Smile | :)

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
bool ignore_box = true;
if (DataBinder.Eval(e.Row.DataItem, "Ignore") != null)
{
if (DataBinder.Eval(e.Row.DataItem, "Ignore").ToString() != "Y" || DataBinder.Eval(e.Row.DataItem, "Ignore").ToString() != "N")
{
ignore_box = (bool)DataBinder.Eval(e.Row.DataItem, "Ignore");
}

if (ignore_box == true)
{
((CheckBox)e.Row.FindControl("chkIgnore")).Checked = true;
}
}
}
}

You're calling this method three times because...... ????

You're assuming because the the field is not a string starting with Y or N ( and not y, n, t, T, F, f, or any other letter or character ), it must be a bool. Either your data source is seriously messed up, or your understanding of how this works is. Judging from the error message you're getting, I'd say the latter. You can't just convert anything to a bool, it has to be a bool. It's obviously not. At a minimum, you should put this code in a try/catch, and then set a default. Probably, you should replace it with a default.

Hi
I managed to sort it

The database field was set as nvarchar so I changed it to bit.
Then I changed or the N and Y to 0 and 1

Its all working now!

Its always better when you fix it yourself Smile | :)
