Hi

I have A Problem With my javascript,

ERROR: 'txtbox1' is undefine in javascript

What i want to achieve:

I have 1 textbox in my Gridview and i have Modalpopup, i want to transfer data from modalpopup to Gridview's Textbox like User will enter Text into modalpopup's Textbox and Text should go to Gridview's Textbox  for that i have below code:

 CODE BEHIND:

'Get a programmatic reference to the CheckBox control

'Dim cb As CheckBox = CType(gvr.FindControl("chkBox1"), CheckBox)

'ClientScript.RegisterArrayDeclaration("CheckBoxIDs", String.Concat("'", cb.ClientID, "'"))

'TextBox1

ClientScript.RegisterArrayDeclaration("txtbox1IDs", String.Concat("'", textbox1.ClientID, "'"))

'txtNotes

ClientScript.RegisterArrayDeclaration("txtNotesIDs", String.Concat("'", textboxNotes.ClientID, "'"))

ClientScript.RegisterArrayDeclaration("txtbox2IDs", String.Concat("'", textbox2.ClientID, "'"))

'txtComments

ClientScript.RegisterArrayDeclaration("txtCommentsIDs", String.Concat("'", textboxComments.ClientID, "'"))

Next

JAVASCRIPT:

//for adding notes here...

//for adding comments

Try using the Register DataItems of the ScriptManager and then in the Javascript that is referenced by the ScriptManager you would write your code there in Javascript to do what you want it to do.

Hi

It seems you are sure about it, but sorry i am not much aware about what you are trying to say,

please tell me with some example, if possible.

Thanks

Hi Parth.

To start, place the gridview in an update panel. When the modalpopup appears, there is a textbox and two buttons - one for ok and one for cancel. When the user types whatever in the textbox and clicks ok, in code behind, you will want to update the gridview (if the data for the gridview is being populated from a database, update the gridview and then bind it again so that it refreshes.) In order for the button to work, you have to use this code

btnok.onClientClick = string.format("postback({'0}', '{1}')", btnok.UniqueId, "")

in javascript do:

function postback(sender, e){

 __doPostBack(sender, e);

}

You must also set the CausesValidation property of the button to False. With all that set, you can then access the code behind for the button and have it asyn update the gridview.

Hope that helps!
