Hi,
I`m testing Your chart.
I need bind large data source (in my solution I must show data for a month, which is more less 3000 items).
When I try do this, it takes very long time (10 seconds). In addition you draw major grid lines for each item (StepValue doesnt work for XAxis - on XAxis are dates). And It looks bad (look at attachment).

Is there way to increase performance in chart?
How set StepValue on XAxis for dates?

Pdf Export autosizing?

I'm exploring the PDF Export example, and the PDF created looks good except for the grid being too wide for the normal page and runs off the edge. I see PageSize options, but I'm not sure how to measure the grid, control the grid width, or otherwise control the output.

Ideally, I'd love to set landscape mode, and either shrink the grid to the page width or have different columns on alternating pages. I'm just getting started with the Pdf export; what kind of ExportSettings & Pdf options should I be looking for to accomplish this?

I'd also be very happy to have the page size set to a non-standard page width so the grid fits. Is there an autosize option like this?

public void ExportPdf_Click(object sender, EventArgs args)

{

RadGrid1.ExportSettings.Pdf.BorderType = GridPdfSettings.GridPdfBorderType.AllBorders;

RadGrid1.MasterTableView.ExportToPdf();

}

Remove selected file automatically on clientvalidationfailed

Hello,

My problem is with the client-side file validation. It works, which is great, but I can't figure out how to do anything useful when a file is not valid.

Specifically, I'd like to stop it from showing up as a selected file - so if a user tries to upload an invalid file I can just issue a warning and have the RadAsyncUpload control revert to its initial state. Why is there no option to cancel in the OnClientValidationFail event? And why is there no option to reset the input from the client-side object?

Right now, when a file fails validation, it still shows up and a user has to manually remove it before trying another upload. I'd rather have the control ready for use again immediately.

I've been looking through the documentation and these forums, and I'm quite surprised no one else has this requirement. Am I missing something simple?

Thank you,

Allan

Group Footer descriptive title text

In my grouping grid I've got group footer columns turned on and am hiding the columns I am grouping by. Works great, thanks for the good documentation!

Next, I'd like to put a "title" or "descriptive text" into the footer so the user knows quickly which item this footer row is summarizing. It's basically the same text as in the Group header, though I might want to customize it. (See attached screenshot mockup.)

My footer would then look like:
| Account Group: 30 - Net Sales, subject to VAT 0 -1,000 801 -1510 ... |

Today it just has the totaled numbers to the right, no text title to the left.

[Solved] I have an issue about Group Footer.

Hello,

I want to set color in group header row and group footer row. I am able to set individual color for each group header row and its working ok.
But I can’t do this for group footer row. I have 3 fields for grouping also have 3 group header row and 3 group footer rows.
Header rows color is ok. But I can’t set color for group footer row for a specific group header row. (Example: GroupFooterRow1 for GroupHeaderRow1)

Please see in attached image. Yellow color mark have wrong footer color, this color should go under 2 rows.

protected void RadGrid1_OnPreRender(object sender, EventArgs e)
{
var j = 0;
foreach (GridGroupFooterItem footerItem in RadGrid1.MasterTableView.GetItems(GridItemType.GroupFooter))
{
if (j == 0) { footerItem.Style.Add("background-color", "#23A323");}
else if (j == 1) {footerItem.Style.Add("background-color", "Green");}
if (j == 2){footerItem.Style.Add("background-color", "#035E03");}

j++;
if (j == 3)
j = 0;
}
}

Is it possible to get group footer row for a specific group header row? (Example: GroupFooterRow1 for GroupHeaderRow1, GroupFooterRow2 for GroupHeaderRow2)

Custom filter not working on first save

I've created a simple custom filter to set some default image spacing in content.

However, the filter is not getting applied to new content when its submitted the first time.

When I reload the content and save it a second time, the filter does its thing.

What might I be missing?
