HtmlInputButton - force the .click() event

[GornHorse]

G'Day,

 

I have a combobox that has the following child controls - cbDBButton (HtmlInputButton), cbDBHidden (HtmlInputText), and cbDBText (TextBox). I have declared each of these child controls on the server-side.

 

Ie, cbDBButton is declared as:

Public WithEvents cbDBButton as new System.Web.UI.HtmlControls.HtmlInputButton

 

Then, in the page_load, i declare the following:

cbDBButton = cbDB.ProcessButton

cbDBButton.ID = "cbDBButton"

cbDBButton.Attributes("runat") = "server"

 

cbDBHidden = cbDB.Hidden

cbDBText = cbDB.TextBox

cbDBText.Attributes("onchange") = "DumpData();"

'(NB that cbDB is the combobox control)

 

Ok, now the DumpData() function gets called fine (javascript). However, what i need to do from here is force the cbDBButton's serverclick event, so that it can call the sub which handles the event.

 

I have tried the following:

Document.Form1.cbDBButton.click();

 

But, i get the following error:

'Document.Form1.cbDBButton' is null or not an object.

 

How can i force the cbDBButton.click() event from the client without getting this error?

 

A quick reply would be excellent.

 

 

Ta,

Michelle

You could amend your DumpData JScript function to take the button as a parameter. The you could change this line:

cbDBText.Attributes("onchange") = "DumpData();"

To this:

cbDBText.Attributes("onchange") = String.Format("DumpData({0});", cbDBButton.ClientId)

 

That should work...

G'Day,

 

Thanks for that. Just one quick question (to prove my uselessness), how do i then use the paramter in javascript?

 

How do i pass this parameter and fire the .click() event?

 

Thanks very much,

Michelle

Ok,

Perhaps you can scratch that last query... maybe.

 

I have done this...

 

Function DumpData(btn){

btn.click();

}

 

Except, now i get the error:

cbDBButton is undefined.

 

Please help??!!

 

Thanks again,

Michelle
