Try using:

Hello,

To be quite correct, it's better to take a look at the member list of the ASPxClientButton object within our help file. There, you can find information about all available client members of a button control. Among them, there is a SetEnabled method, which we recommend to use to change button availability to end-users on the client.

 thank you very much Mr Andrew, your answer was very interessting

and thanks also for Mr Brendon.

Hi Andrew!

Have some strange things using ASPxClientButton.

My Code is :

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} <dxe:ASPxButton EnableClientSideAPI="true" ID="btnEmail" ClientInstanceName="btnEmailClient" runat="server" Text="Email" onclick="btnEmail_Click">
</dxe:ASPxButton>

then in JS handler I call "btnEmailClient.Enabled = (gridDocs.GetSelectedRowCount() > 0" (I know it is possible to us SetEnabled now).

When executed it tells that  btnEmailClient is not defined.

When I view html page source I see that it is actually not.

(gridDocs - which also uses ClientInstanceName="gridDocs" is there  and works.

like - "var dxo = new ASPxClientGridView('ctl00_cphBody_ctrlQuoteDocs_gridDocs');")

What's with it ?

When I did web search for ASPxClientButton but it didn't found much and nothing in DX help.

Hope on your reply.

Hello All!

I want to report that I found way to resolve problem that I described in the previous message.

It resolved by readding buttons to the form, but before I checked out for edit files licenses.licx and App_Licenses.dll.

The matter is we have exclusive lock in our CVS (TFS) and when one man edits file another one can't change it.

So as this files are changed frequently it is constantly locked - everything works good beyond client API.

Think it is the matter.

Thank you, hope that it may help someone else!
