Help with Gridview and image button

[glbdev]

Hi,

I posted this question yesterday but didn't get the answer I needed.
I am DESPERATE to get this working so I'm re-posting it because I
don't think I worded it correctly.

I have a GridView which is databound to a table. All the data is
being pulled correctly so there is no problem there.

On each row I have an image button which is attached to a
DataTextField, pulling up a uniqueidentifier for that record. Here is
the HTML for it:

<ASP:BUTTONFIELD BUTTONTYPE="Image" IMAGEURL="~/images/ViewEmps.gif"
TEXT="Button" DATATEXTFIELD="EmployeeNumber"
COMMANDNAME="EmplayeeDetails">
<ITEMSTYLE HORIZONTALALIGN="Center" VERTICALALIGN="Middle"
WRAP="False" />
</ASP:BUTTONFIELD>

When I hover above this button it shows me the correct DataTextField
value for each row. I have the code in place so that when the user
clicks on this button it redirects them to another page. No problem,
everythings fine to this point.

The problem I am having is that I need to get the DATATEXTFIELD value
from the button so I can use it as part of a querystring, such as:
Response.Redirect("EmployeeDetails.aspx?id=" +
button_datatextfield_value)

How can I get this DATATEXTFIELD value? Can anyone help with this?

Again, sorry for the re-post but I, obviously, didn't explain the
problem correctly and I am desperate to get this working since I am
going to be using gridviews on several different pages and am stuck
without it working correctly.

Thanks,
Steve

Maybe i don't understand properly your idea, so my code no usefull for you.
I think you can give data though CommandAgrument attribute from Button
control.
For example:

[Design]

<asp:button text="click here" CommandAgrument='<%#
Eval("EmployeeNumber") %>' OnClick="OnClickRedirectButton" />

[Code behind]

protected void OnClickRedirectButton(object sender, EventAgrs e) {
Button btn = sender as Button;
int employeeNum = int.Parse( btn.CommandAgrument );
Response.Redirect("EmployeeDetails.aspx?id=" +employeeNum );
}

I hope this post could help you

I appreciate your help. Problem is that there is no "onclick" event
for a button on a gridview and "CommandAgrument" seems to give only
the row # associated with that button. I need a button that's on a
gridview (<ASP:BUTTONFIELD BUTTONTYPE="Image") not a regular button
(<asp:button text="click here"), they seem to work differently. I
need to return (or somehow obtain) the DataTextField value that is
assigned to this button.

Any ideas on how to do this?

Thanks,
Steve

Come on, someone, anyone? There has GOT to be a way to do this but I
cannot figure out how. Someone must have done this before.

On each row I have an image button which is attached to a
You say that the value in DATATEXTFIELD is a unique identifier for the row.
And you are able to get the row number in your event handler. So assuming
you have DataKeyNames="EmployeeNumber" on the grid itself, you could do
this:

protected void PaidInvoices_RowClicked(object sender,
CustomGridView.GridViewRowClickedEventArgs args)
{
Response.Redirect("ViewInvoice.aspx?id=" +
PaidInvoices.DataKeys[args.Row.RowIndex].Value.ToString(), true);
}

We use a custom grid view derived from the basic grid view so the event name
and command args are different, but you should get the idea. Basically you
want to inspect "GridView1.DataKeys[rownumber].Value".
