c# - ImageButton in UpdatePanel doesn't PostBack -


I have created a form in a popup window, in which it is UpdatePanel with ImageButtons.

Initially, I used to test linkbutons, but I need image buttons. The thing is, it works well with linkbutton and the image is not with buttons (absolutely nothing happens).

Checking the source, I think the Javascript call is slightly different:
link button: 

; a href = "javascript: WebForm_DoPostBackWithOptions (New WebForm_PostBackOptions (& amp; quot; ctl00 $ CPHC $ ctrlAdr $ AdrMapo $ lbAdresseSaisie & amp; quot;, & amp; quot; & amp; quot;, true, & amp; quot; & amp; quot;, & amp; quot; & amp; quot,;, false true)) "id =" ctl00_cphC_ctrlAdr_AdrMapo_lbAdresseSaisie "& gt; Trial & lt; / A & gt;

ImageButton: 

  & lt; Input align = "absmiddle" type = "image" style = "border-width: 0px;" Onclick = "javascript: WebForm_DoPostBackWithOptions (New WebForm_PostBackOptions (& amp; quot; ctl00 $ cphc $ ctrlAdr $ AdrMapo $ rpAdressesProposees $ ctl00 $ ibAdresseProposee & Amp; quot ;, & amp; quot; and & quot; true, & quot; & amp; quot ;, & amp; amp; quot ;, & quot; false, false)) "... & gt; ; After

Check out the document, I think that called WebForm_PostBackOptions last parameter clientSubmit and set it , Then a true is submitted to one. This value for the ImageButton is set to false and if I do it true manually do changes with Fayrbg, if it works as expected but whenever control ready If so, then I can not find any way to change that parameter. And I am quite upset

If i ImageButton.CausesValidation is set, there is no generated JavaScript and when I click on the button then nothing happens UpdatePanel This is declared as:

And to ensure that I declare a trigger for ImageButton. I use UpdateMode = "conditional" because it needs to be updating updating updatesPanel events from programmingly.

LinkButton correctly presented in the same situation, so I do not know what I have done wrong ...

Is there a client-side validation that is blocking postbacks? Do you do a postback, if you remove the update panel from the page? I do the tests so that you can determine whether this is a problem with UpdatePanel + ImageButton or just Imagebutton.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
