Question

I have the following GridView

<asp:GridView ID="grdImoveis" runat="server" DataSourceID="dsGrid">
                    <Columns>
                        <asp:BoundField HeaderText="Nome" DataField="NomeCompleto" />
                        <asp:ImageButton ID="ibtnAlterar" ImageUrl="../tema/_Internas/icons/edit.png" runat="server" OnClick="btnChange_Click" /> 
                    </Columns>
</GridView>

How can i get the value of this field in code behind and pass the value to my btnChange_Click event ?

Answer 1

If your asking what I think, you’d like want to handle the OnRowCommand of your GridView and capture the button action in there.

<asp:GridView ID="grdImoveis" onrowcommand="grdImoveis_RowCommand" ...

Code-Behind:

 protected void grdImoveis_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "BUTTON")
        {
            // Check value of e.CommandArgument and do something here:
        }
    }

And change your imagebutton to something like so by setting CommandName and CommandArgument to the value you want to pass. You also have to wrap it in a TemplateField:

<asp:TemplateField>
            <ItemTemplate>
<asp:ImageButton CommandName="BUTTON" CommandArgument='<%#Eval("NomeCompleto") %>' ID="ibtnAlterar" ImageUrl="../tema/_Internas/icons/edit.png" runat="server"  />
</ItemTemplate></asp:TemplateField>
