scripting using Button

[stephen]

Hi Steve,

Sorry if you have seen this post before but I cant figure this one out...

Thanks for the information but now I am getting new errors:
I have used this code in the rowdatabound, how do i modify this to take 2
values?

protected void dgCustomer_RowDataBound(object sender, GridViewRowEventArgs
e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton myLink = (LinkButton)e.Row.Cells[0].Controls[0];
myLink.OnClientClick = "window.returnValue=" + e.Row.Cells[1].Text +
";window.close();return false;";

}

}
I want to return e.row.cells[2].text
I tried
myLink.OnClientClick = "window.returnValue=" + e.Row.Cells[1].Text +
"window.returnValue=" + e.Row.Cells[2].Text +
";window.close();return false;";


Thanks,
Stephen

There really is no point in saying you're getting (new) errors if you don't
actually tell the group what those (new) errors are...

myLink.OnClientClick = "window.returnValue=" + e.Row.Cells[1].Text +
";window.close();return false;";

Where are you actually opening the window...?

Hi Mark,

the original post was like this:
I want to select and return values from a datagrid so I added this line in
the parent page (based on suggestion from Steve, a MVP)
<INPUT id=btnFindContName
onclick="document.getElementById('blbContractNumber').innerHTML =
window.showModalDialog('FindCustomer-1.aspx?num='+document.getElementById('blbContractNumber').innerHTML
+ '&name=' +
document.getElementById('blbContractName').innerHTML,'','width=300,height=300');"
type=button size=5 value=Find... name=findContractName>

I wanted mutliple values to be sent across from the child
(FindCustomer.aspx) page and have this in the GridView_RowDataBound Event

protected void dgCustomer_RowDataBound(object sender, GridViewRowEventArgs
e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton myLink = (LinkButton)e.Row.Cells[0].Controls[0];
myLink.OnClientClick = "window.returnValue=" + e.Row.Cells[1].Text +
"window.returnValue=" + e.Row.Cells[2].Text +
";window.close();return false;";
}
}

Now I get script errors when I click the parent page's button its giving me
http://localhost:1679/FindCustomer.aspx?num=&name=
and ';' expected
and when I select from a datagrid it open a brand new window and display
with page cannot be displayed.

hope I make sense,
Thanks for your help,
Stephen

That simply means that you have a syntax error somewhere in your
JavaScript - enable client-side debugging and step through it or, at least,
inspect the rendered JavaScript in the View Source to find out where the
error is...

It looks like the window.returnValue property returns only a single
value, and is only used in combination with modal dialogs, which can
only return a single value.

Using the modal dialog method, the only way to *effectively* return two
values is to concatenate both values, but separated with a "---" or some
other character. Then when your dialog returns, separate the two values
again. It's not the most elegant design, but it's the only way when
you're using a modal dialog.

What about this code:


<INPUT id=btnFindContName
onclick="document.getElementById('blbContractNumber').innerHTML =
window.showModalDialog('FindCustomer-1.aspx?'+document.getElementById('blbContractNumber').innerHTML

+ '---' +
document.getElementById('blbContractName').innerHTML,'','width=300,height=300');"

type=button size=5 value=Find... name=findContractName>


This should get the two values returned (as one value). Just split the
values in your dgCustomer_RowDataBound() sub before you , and you should
be good to go.

Yes but, like all JavaScript variables, the returnValue is a variant...

Using the modal dialog method, the only way to *effectively* return two
values is to concatenate both values, but separated with a "---" or some
other character.

I just use an array...
