I have a gridview which lists Tools and Access values. To edit I have an edit imagebutton on each row. I have an OnRowBound method which assigns an OnClick attribute to each button so that I will know which record I need to edit. The code is
Protected Sub ChangeFirstRowIcon(ByVal Sender As Object, ByVal e As GridViewRowEventArgs) Handles gv_AccessRights.RowDataBound
'This sub fires on each gridview row created...
'It first checks that the row is a data row (as opposed to Header, Footer etc.)
'If ib_Edit is true then change add an attribut to button with aid, tid and ac values attached.
If e.Row.RowType = DataControlRowType.DataRow Then
Dim ib_Edit As ImageButton = e.Row.FindControl("ib_Edit")
Dim lb_AccessID As Label = e.Row.FindControl("lb_AccessID")
Dim hd_ToolID As HiddenField = e.Row.FindControl("hd_ToolID")
Dim hd_AccessCode As HiddenField = e.Row.FindControl("hd_AccessCode")
If ib_Edit IsNot Nothing Then
ib_Edit.Attributes.Add("onClick", "proxyClick('" & lb_AccessID.Text & "', '" & hd_ToolID.Value & "', '" & hd_AccessCode.Value & "')")
End If
End If
End Sub
I'm using a hidden proxy button to show a modal popup which the user will use to edit a record... (the same popup will be used to add a new access record... but that will come later). So having passed my details to proxyClick I set values to controls within the modal popup. The javascript is....
<script type="text/javascript">
function proxyClick(aid, tid, ac) {
document.getElementById('hd_AccessID').value = aid;
document.getElementById('hd_ToolIDMod').value = tid;
document.getElementById('hd_AccessCodeMod').value = ac;
document.getElementById('but_SetModalDetails').click();
}
</script>
For reference the main bits of the markup are....
<table class="border">
<tr>
<td>
<asp:Button ID="but_SetModalDetails" runat="server" Style="display: none" Text="Set modal details" ClientIDMode="Static" UseSubmitBehavior="true" />

As you can see I have implemented two hidden buttons but_SetModalDetails and but_HiddenProxy. but_SetModalDetails has some codebehind which sets a couple of dropdown lists (one populated from a datasource, the other is populated dynamically based on the value of the first. The codebehind is...
Protected Sub but_SetModalDetails_Click(ByVal sender As Object, ByVal e As EventArgs) Handles but_SetModalDetails.Click
If hd_AccessID.Value = "0" Then
lb_ModTitle.Text = "Assigning Access Rights to:"
ddl_ToolName.SelectedIndex = 0
ddl_AccessCode.SelectedIndex = 0
ddl_AccessCode.Enabled = False
Else
lb_ModTitle.Text = "Edit Access Rights to:"
ddl_ToolName.SelectedValue = hd_ToolIDMod.Value
ddl_ToolName.Enabled = False
SqlStr = "SELECT AccessID AS ddlValue, AccessText as ddlText FROM tbl_AccessCodes WHERE ToolID = " & hd_ToolIDMod.Value
PopulateDDLvalue(ddl_AccessCode, SqlStr)
ddl_AccessCode.SelectedValue = hd_AccessCodeMod.Value
ddl_AccessCode.Enabled = True
End If
'NOW I NEED TO SIMULATE but_HiddenProxy Click
End Sub
As you can see at the end I need to simulate a click of but_HiddenProxy so that the modalPopup is shown populated with the correct data.
Any Ideas? Thanks
