well nested controls means if u have a user control, within tht there is an other, n with the innerone there is another one and so on and in the fifth control u have an asp.net control. it would be difficult to make properties instead of tht method ,tht i've mentioned is quiete simple to me. i don't how do u find it. but i find it quite simple.
regards.

Hi,
Did this work at your side?
I have tried this but its giving me NullReferenceException.
I have a usercontrol "GetCategory.ascx" in that there is one gridview with id "gvSearchResult".
I put "GetCategory.ascx" in to "Parent1.ascx" then I put "Parent1.ascx" in to "Parent2.ascx".
I used "Parent2.ascx" in to my Text.aspx page.
and write the following code in the Page_Load event of "Text.aspx".
GridView gv = ( GridView )Parent2_1.FindControl( "gvSearchResult" );
Response.Write( gv.ID ); // On this line it gives me NullReferenceException. Means it could not find controls with "gvSearchResult" in Parent2_1 control on the page.
Can you tell me why is it like that or am I making any mistake?
Thanks and Regards,
Chetan Ranpariya

hi,
well....
yes definitely u r committing mistakes.
first tell me tht when u execute
GridView gv = ( GridView )Parent2_1.FindControl( "gvSearchResult" );
above line, have u bound the gridview.
now, if u've bounded it, still u r commiting a mistake in the following line;
GridView gv = ( GridView )Parent2_1.FindControl( "gvSearchResult" )
the correctone is:
GridView gv=(GridView) Parent2_1.findcontrol("parent1").findcontrol("getcategory").findcontrol("gvSearchResult");
keep two things in mind.
u don't have to write the names infact there ID must be written given to findcontrol method.
and second thing is make sure ur datagrid is filled before u findit.
these are the two reasons which u need to correct...
hope it works.
regards.

Hi,
I am executing that line after binding the gridview in the usercontrol
and by the way there is no need to bind the gridview before you access it in your code because to bind gridview to any datasource you need to have an access to instance of gridview.
Try it!!!!!!!!!!!!!!!!
Your solution to find controls in the usercontrol is good but for that one should know about the IDs of all the controls and their types in the all the usercontrols.
What about making related properties whereever need in all the controls so that they can be used with without worrying about types and IDs of nested controls and the undelaying complaxity because properties are there for hide complexity only and improve the accessibility and readbility.
Think on it!!!!!!!!!!!!!!!!!!!!!!! 
Thanks and Regards,

well the thing is....
fine u can access datagrid before using it. but before accessing any value from the grid it must contain something. fine i agree.
n as far as the second thing is concerned,
i find this way easy.
if u find, writing hundreds of lines of code, easy then there is no prob at all. i didn't say its wrong but for me atleast its tiring.
ne ways every buddy has his own logic and view. so wish u gud luck..
take carez

Hi,
I have a datagrid for which i have implemented paging. If there are no records in the datagrid then i dont want the pagerstyle mode to be shown.
i.e. i dont want the page numbers to be shown if the datagrid is not having any values.
Thanks,

Hello,
It seems that the assembly ADODB is not in the correct directory.
Also, I did a quick google search about ADODB, it appears to be a PHP library. If it's the case, you cannot use it in .NET

Of course you can use it. You need to put adodb.dll in your applications' bin folder. It is probably already on your computer (do a search fr it) or drop me an email and I'll send you it.

Hi,
There is no way to delete column from gridview.
Better you make is invisible.
gv.Columns[colindex].Visible = false;
I hope this will help you.
