[Solved] Custom Image Column?

[sitefinitysteve]

My grid is databound, and the last 3 columns give me a status text message (approved, rejected, etc, etc)

Can I make a new column after that (non-databound) which just checks the status, then I can insert a corrosponding image?  Like a checkmark if all 3 are approved for example...

Regards,
Steve

Hi Steve,

Please check the last column in this example:

Hi Steve ,

You can use a GridTemplateColumn to achieve the desired scenario.

ASPX:

<telerik:GridTemplateColumn UniqueName="TempCol" HeaderText="TempCol"   >
                          <ItemTemplate>

                          </ItemTemplate>
                        </telerik:GridTemplateColumn>

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            string strcol1 = item["BoundCol1"].Text.ToString();
             string strcol2 = item["BoundCol2"].Text.ToString();
             if ((strcol1 == strcol2) && (strcol1 == "approved"))
             {
                 Image img=new Image();
                 img.ID="Image1";
                 img.ImageUrl="~/Images/Check.gif";
                 item["TempCol"].Controls.Add(img);
             }
        }

Thanks

Possible there is a sample of How to Create Custom Image column (column for showing images) without useg Template Column?

[Sebastian]

Hello Maxim,

In the present version of RadGrid for ASP.NET AJAX you can use only a template column for this purpose.

However, you may be happy to know that we plan to introduce new built-in GridImageColumn for the next version of the product, expected in the beginning of July. With it you will be able to specify image url fields and image url format string to display different images in the same column.

Hello Sebastian!

I would be greate! because my customer wants to see small preview of Image, which was stored in database - by clicking of Images I show full-size Image. But my custom solution deosn't work properly.

[Sebastian]

Hello Maxim,

Unfortunately images thumbnails with preview option will not be supported by that new grid column.

However, you may consider intercepting the onclick client event of the image from within the ItemCreated event of the grid and display it in full size inside RadWindow instance with approach similar to this one (using asp Image instead of Hyperlink inside the template column).

Kind regards,

Hello Sebastian,
So, I've just wrote about my actual task. My aim is to put special link on aspx page for showing image in cell. Server page will put small preview image into output stream .... Thing that new GridImageColumn can help me in this problem, and sure In any cases there are 'good' events:  ItemCreated, ItemDataBound.

Thanks a lot for supporting, and for Great UI library.
