Hide the column in the DataGrid.
Set the columns in the designer and set visible to false for the columns you don't want displayed.

Can you detect the back button and fire an ASP event before you navigate away? Actually, can someone show me how to fire an ASP event and also a JavaScript function call? That would be best. I'll need to do both.
As always, a URL to somewhere else is just fine with me.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

hello
thanks for the time
I have just a short time programming
i have the next scene :
for example when the page is load you use a field hidden to load it with data that you usen in then side client
for example a textbox hidden you load text property with country and
depend the user activity in the side client yo have have conditions for the type the country that data's field hidden
it is a simple example because with this technique there are bad scenes
some one could say me what is the correct way to work with data
between server side y client side in asp net

I have four projects and everytime if i do changes in any signature or add any new method etc in any one project then i need to remove all reference and then include them again. ....This is very painful to do this everytime during project coding stage....
Is there any way to get rid of this. I had created macro but i am not so happy with this solution....

Add a reference to the project rather than the assembly.
Project A needs to include output from Project B & C so you add a reference to Project A and select the project tab, then add Project B & C, provided these are all in the same solution.

i have 3 combo boxes (first combo box's selection determines the next ones content)
so when user selects first Postback occurs and page refreshes and the content in the second combobox changes.
Now all is working well,
however on a slow connection user selects first combo box and then quickly tries to select the second one but the post back hasn't returned yet... so how can i disable the page/comboboxes once the user makes his selection.
i hope all that made sense i am terribly new at this (and yes i am using asp.net and c#) 
If you think you can than you can, if you think you can't you are right.

Basically, if you want to disable an element at client side, you can use javascript to set the disabled[^] to true. So in this case, if you want to disable the second dropdownlist once the user makes his selection on the first one, you can use the onchange event of the first dropdownlist to run your script to disable the second one. The sample code to register the script looks something like:
DropDownList1.Attributes.Add("onchange", "YourDisableScript(...);");
One more thing that you might should know is that when an input element like dropdownlist or textbox ... is disabled, its value is not submitted to the server when the page posts back. So if you want to disable the first dropdownlist, you will need to persist the value in a hidden element so that you can populate the second dropdownlist. Also, you might also consider using ajax in this case instead of posting the page back to populate the other dropdownlist based on the selection of the first one.

I am using the asp menu control.The menu is horizontal orient. It works fine with the english part when i try to use it with arabic style right to left the dynamic menu starts from the left side as it works in english. I have given the direction as rtl the popout of the dynamic menu comes in the right side. The problem is the dynamic menu which popouts from the static menu is aligning to the left of the static menu. The dynamic menu should be aligned to the right side of the static menu.

What does your code look like? Basically, the ASP.NET generates a dynamic class at runtime which inherits from the class defined in code-behind. If the function is defined as private, it's not accessible to the child class, it needs a higher access level like protected or public.

In the OnCreatingUser event handler, you can set the Cancel property of the event data instance to true after you add data to your own store.
