well the above solution is fine but if u have five nested controls then for one control u'll have write a lot of code, properties or whtever...
there is an other solution,

u could use the folling code....
ctype(UserControlid.findControl("RequiredControlID"),textbox).text
thts it.

hope it works for u.

Can you please elaborate the thing?

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.

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,

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!!!!!!!!!!!!!!!!!!!!!!! Smile | :)

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

1)u have to diclare a public propety in the usercontrol like
public string propertyname()
{
get
{
return textbox1.text;
}
set
{
textbox.text=value;
}}
2)refer it in the html view by making use of Registertag

<%@Register tagprefix="" tagname="" src=""%>
