problem with INamingContainer

[SatinderGT]

Ya sure,

this is the code for 3 text boxes generated:


</div><div id="Panel1" style="height:212px;width:380px;Z-INDEX: 102; LEFT:
439px; POSITION: absolute; TOP: 386px">
Panel<span id="Sat"><table id="Sat_tblEntry" border="0">
<tr id="Sat_ThisRow1532">
<td></td><td></td><td><input name="Sat:ThisRow1532:TXT1532" type="text"
id="Sat_ThisRow1532_TXT1532" /></td><td></td>
</tr><tr id="Sat_ThisRow2663">
<td></td><td></td><td><input name="Sat:ThisRow2663:TXT2663" type="text"
id="Sat_ThisRow2663_TXT2663" /></td><td></td>
</tr><tr id="Sat_ThisRow3726">
<td></td><td></td><td><input name="Sat:ThisRow3726:TXT3726" type="text"
id="Sat_ThisRow3726_TXT3726" /></td><td><span id="Sat_ThisRow3726__ctl0"
controltovalidate="Sat_ThisRow3726_TXT3726" errormessage="test me"
display="Dynamic"
evaluationfunction="RegularExpressionValidatorEval uateIsValid"
validationexpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
style="color:Red;display:none;">test me</span></td>
</tr>
</table></span>

Just for your info:

I even tried to use page.findcontrol and set the uniqueid, clientid and id
properties individually for the control, but it doesn't works!!!

Also, i tried to set Sat:ThisRow1532:TXT1532
Also, i tired to set ThisRow1532:TXT1532
Also, i tried to set Sat_ThisRow1532_TXT1532

But, all in the above cases it fails and says control not found.
JUST TO REMIND AGAIN WHEN I AM RENDERID "TXT3726" AT THAT TIME I M TRYING
TO VALIDATE "TXT1532",
REASON: I WANT TO USE COMPAREVALIDATOR ON IT.

Waiting for reply,

thanks in advance,
satinder

Okay, I have been researching this for a while and here is what I came up
with. The short answer is to NOT use INamingContainer. However, not using
it, you will have to come up with your own naming scheme to guarantee there
are not any duplicate names.

Using INamingContainer will guarantee all controls added with have a unique
name. What is happening is the naming interface is giving the textbox
control a unique name: sat_thisrow1532_txt1532. When the sat_thisrow3726 is
rendering the validator on it is to txt1532, but it is being appended with
sat_thisrow3726_txt1532.

I looked and could not find a way to override the interface functionality
for a validate control id.

Points.

1) are you sure it is required to implement the INamingContainer? Could you
just implement your own naming scheme when you added the controls? ie
append the row name and id before the type. Kinda mimick the
INamingContainer functionality?

2) You could write a custom control for that cell, that inside the cell, you
write out the validator by hand. It is kinda a hack that way, but you know
what the html is supposed to look like, just look into registering a
validator with the page and go from there.

Sorry I couldn't be of any more assistance.

I created a composite control which works just fine. I want to be able to
set the focus to one of its contained controls (a textbox) but this is
giving me a javascript error. The problem is that the ClientID property of
the contained textbox is not giving me the correct value. When I debug the
application the contained textbox's ClientID is "myControl__ctl1", but when
I look at the generated HTML the input tag looks like this: <input
name="myControl:_ctl1" ... />

How did the first "_" turn into ":" and how do I fix this?

You don't, really. The ID will be NamingContainerID_ChildID, and the
name will be NamingContainerID:ChildID. That's just the way it works.
If you're using Javascript, you could do
document.getElementById(ClientID).focus()

Otherwise, you're going to have to override Render and manually set the
name equal to the id. That's a pain, and unnecessary.

[Sergio FLorez M.]

Actually, that's exactly what I was using -
document.getElementById(ClientID).focus()

The solution is really simple. Instead of ClientID I have to use UniqueID.
