RE:number of photos in lightbox or image gallery

Hi Gary,

Unfortunately, there is no such a variable. But you could add some asp:Literal control into transformation and write custom code-behind to get the DataSet of repeater and set the number of rows of DataSet to Text property of Literal in order to display it in transformation.

RE:number of photos in lightbox or image gallery

Hi Gary,

I've realized that using procedure I suggested the count would be displayed for every item in the list. I suppose you want to display it only once on page. If so, could you please try if procedure described in How to display number of records of repeater article suits your needs?

RE:number of photos in lightbox or image gallery

thanks for suggestion,

I have followed the procedure :
1) add ltlRepeaterCount to CMS Desk --> Development --> Listings and Viewers --> repeater_promotion
2) add the code

There are errors occured.

[Error loading the WebPart 'repeater_promotion']
c:\mh.e-crusade.com\CMSWebParts\Viewers\cmsrepeater_promo.ascx.cs(778): error CS0103: The name 'ltlRepeaterCount' does not exist in the current context

Can you explain the procedure adding add asp:Literal control with ID = "ltlRepeaterCount" and how can i display the count of repeated item into transformation?

Thanks

However, the repeater doesn't show anythings but none of error. Also, how to show the number of items looped by repeater? Please advices. Thanks


Member	gary.chan-e-crusade - 7/19/2009 10:16:06 PM RE:number of photos in lightbox or image gallery Hi, finally i can use the coding to display number of item in repeater. However, I don't know how to put the output number (which display at the left corner of repeater) into my transformation. Please advices. Thanks


Kentico Developer	kentico_helenag - 7/20/2009 7:38:40 AM RE:number of photos in lightbox or image gallery Hi Gary, I would recommend you to style the Literal (using CSS styles) and place it where you need it. The Transformation would display the number of rows in each data row so I think it is not useful in your case. Best regards, Helena Grulichova

RE:number of photos in lightbox or image gallery

Hi,

You can surround the literal with span tag and use class attribute to specify the CSS class name. Please find an example below.


<span class="your class">
<asp:Literal runat="server" ID="literal1" Text="some text"/>
</span>

Where your class is name of CSS class that you may need to specify in your CSS. You can find more details about CSS stylesheets in our Developer's guide:

RE:number of photos in lightbox or image gallery

Hi Gary,

If you would like to hide the repeater and show only the number of records you could add a PreRender event to your repItems repeater in your custom control:

<cms:CMSRepeater ID="repItems" runat="server" EnableViewState="true" OnPreRender="repItems_PreRender" />

and then add this code to your code behind:

protected void repItems_PreRender(object sender, EventArgs e)
{
this.repItems.Visible = false;
}

You may play with conditions to achieve your requested behavior.

Best regards,
