Hello!

I'm currently evaluating your tools, i want to access a DetailRow Data when a click a buttom. I undestand that the way you can access the information is providing the visibleIndex to methods like "FindFooterCellTemplateControl", so i can get a specific detail Grid, and then access to its data.

I saw an example in this post..:

http://community.devexpress.com/forums/p/56589/190783.aspx#190783

and i'm running into the following problem. If i do something like this: (into a DetailRow,..)

<dxwgv:GridViewDataTextColumn FieldName="Color" VisibleIndex="1">

<FooterTemplate>
<asp:Button ID="btnSave" Style="float: right" CssClass="button" runat="server" Text="Save"  onClientclick=' masterGrid.PerformCallback(<%# Container.VisibleIndex%>)' />
 </FooterTemplate>

</dxwgv:GridViewDataTextColumn>

Then i get an error telling me that the FooterCellTemplate does not have a member called VisibleIndex... 

But i dont know if i'm being pointed in the right direction..

What i need is to access to a detailRow particular data when i Click on a custom button that is inside of the DetailRow.

Thanks about any help!!

 Hi Rod,

You can do the following:

protected void ASPxGridView1_HtmlRowCreated(object sender, ASPxGridViewTableRowEventArgs e) {

    if (e.RowType == GridViewRowType.Detail) {

        ASPxButton btn = ASPxGridView1.FindDetailRowTemplateControl(e.VisibleIndex, "ASPxButton3") as ASPxButton;

        btn.ClientSideEvents.Click = string.Format("function(s, e) {{ grid.PerformCallback({0});}}", e.VisibleIndex);

    }           

}

Hi Nathan!!, how are you ? :)

Thanks about the two time and quick help!! :)

But i'm running into the following :(..

If i Do the next call in the HTML_ROW_CREATED:

 Dim btn As ASPxButton = TryCast(ASPxGridView1.FindDetailRowTemplateControl(e.VisibleIndex, "ASPxButton1"), ASPxButton ) 'yes! The AspxButtonID is ASPxButton1 :)

as you said..  then i get nothing..  

If I do:

Dim bx As ASPxButton = dg.FindFooterCellTemplateControl(dg.Columns("Total"), "ASPxButton1")

Where DG is the detail row.. Then i get a pointer to the control! But with no success doing this:

bx.ClientSideEvents.Click = String.Format("function(s, e) {{ grid.PerformCallback({0});}}", e.VisibleIndex)

It's simply dont update the ClientSide Event.. and never fires the onCallBack event :(..

Because the code worth more than 1000 words :), This's my code:

VB-------------

Protected Sub ASPxGridView1_HtmlRowCreated(ByVal sender As Object, ByVal e As ASPxGridViewTableRowEventArgs)

        If e.RowType = GridViewRowType.Detail Then
            Dim dg As ASPxGridView = ASPxGridView1.FindDetailRowTemplateControl(e.VisibleIndex, "detailGrid")

            Dim bx As ASPxButton = dg.FindFooterCellTemplateControl(dg.Columns("Total"), "ASPxButton1")

            bx.ClientSideEvents.Click = String.Format("function(s, e) {{ grid.PerformCallback({0});}}", e.VisibleIndex) 'works but, it didnt make the button perform any action..

            'Dim btn As ASPxButton = TryCast(ASPxGridView1.FindDetailRowTemplateControl(e.VisibleIndex, "ASPxButton1"), ASPxButton) 'returns me Nothing..
            'btn.ClientSideEvents.Click = String.Format("function(s, e) {{ grid.PerformCallback({0});}}", e.VisibleIndex) 'wont work if i get nothing from the previous...
        End If

    End Sub

ASPX--------

<dxwgv:ASPxGridView KeyFieldName="keyField" ID="ASPxGridView1" runat="server" AutoGenerateColumns="True"
                        Width="100%" ClientInstanceName="grid" SettingsPager-PageSize="100" DataSourceID="SqlDataSource1"
                        OnHtmlRowCreated = "ASPxGridView1_HtmlRowCreated"
                        OnCustomButtonCallback = "CustomCallBack"
                        >

                                    KeyFieldName="keyField" Width="100%" AutoGenerateColumns="false"
                                    Settings-ShowFooter="true"
                                    OnBeforePerformDataSelect="detailGrid_DataSelect" >

(...)

<Columns>

(....)

<dxwgv:GridViewDataTextColumn FieldName="Total" VisibleIndex="5" FooterCellStyle-HorizontalAlign="right">
                                            <PropertiesTextEdit DisplayFormatString="c">
                                            </PropertiesTextEdit>
                                            <FooterTemplate>
                                                
                                                <dxe:ASPxButton id="ASPxButton1" runat="server" Text="Save2" ></dxe:ASPxButton>
 
                                            </FooterTemplate>
                                        </dxwgv:GridViewDataTextColumn>
                                    </Columns>

<SettingsDetail AllowOnlyOneMasterRowExpanded="True" IsDetailGrid="True" ShowDetailButtons="False" />
                                </dxwgv:ASPxGridView>
                            </DetailRow>

(...)

I'm I missing something?..

Thank again Nathan.

 Hi,

It's better to handle the HtmlRowPrepared event. I've made a sample project for you. Please see it.

Hi Nathan!

Thanks!, exellent way to sell your products :).

Take Care.
