Hello,

I use Radwindow to display notes. There are 4 text fields and 4 buttons to display specific note in radwindow. Everything works fine until I change notes and open popup RadWindow to display saved note. RadWindow shows the old note. So i need to refresh window every time.

So, I have a problem to refresh RadWindow every time it opens. I can not use property ReloadOnShow, because I pass query parameters and telerik adds his own parameters at the end and it leads to error when I try to get query patameters throught Reqest["parameterName"]. I event tried to destroy window every time it closes, but no effect. Then I tried to create new radWindow(throught javascript) every time it opens and destroy after close, but somehow the data is still not refreshed. Then I desided to reload window every time it opens using radWindow.Reload(), but it led me to unexpected effect. I even disabled viewstate and again no effect.

What is the best practice to open radWindow and refresh everytime it opens?

Delete Command not firing for Grid in Chrome

We are having an issue with the Delete command firing in Chrome when using a Command Text. I was able to duplicate this on your demo site.

1) Go to the following link: http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/manual-crud-operations/defaultcs.aspx

2) Delete a record in IE. You will see it works fine. The record disappears as expected.

3) Then do the same using Chrome. The command text pops up as expected, but if you click OK nothing is deleted.

I can duplicate this at will and have uploaded a video demonstrating the issue: https://youtu.be/_-KmZWCE8x8

RadTabStrip OnTabClick

Hello,

I'm using a RadTabStrip control and its OnTabClick event

It's working fine except for when the tab clicked is the active tab.

Then the event doesn't fire at all.

Is there a way to listen to a click event for an active tab ?

Thanks!

Change Autogenerated column from DateTime to short date

I am using a stored procedure to get a DateTable of ID (int) start date and end date (both Date Time). The columns are autogenerated. I want both date time fields to have just the date. I saw in the ItemDataBound to select the columns that have DateTime, but I do not see how to change the values to just date. I am using C#

(if (col,DateType == typeof(DateTime))

{

item(col.?

}

Thanks

Efficient way of adjusting all editors on page

Hi,

i managed to set the width of 1 html editor using this way in the C# code

but my page has about 20 editors and some editor are created dynamically via the asp:Repeater.

RadWindow with NavigateUrl Scrollbar Disappearing in Chrome

Problem: The scrollbars of RadWindow with NavigateUrl is lost in Chrome browser when the visibility of the window is toggled.

Details: The issue stems from a bug in Chrome browser ( Iframe scrollbars disappear when toggling visibility of the iframe element) that is related to scrollbars disappearing of an iframe element when its display attribute is set to "none" and then "". The issue can be seen in this video (http://screencast.com/t/KoBPnfk4ZcMK) and can be reproduced with no Telerik UI for ASP.NET AJAX controls:

HtmlPage.html:

<script>

function showIframe() {

document.getElementById("iframe1").style.display = "";

}

function hideIframe() {

document.getElementById("iframe1").style.display = "none";

}

</script>

<input type="button" name="name" value="Show Iframe" onclick="showIframe(); return false;" />

<input type="button" name="name" value="Hide Iframe" onclick="hideIframe(); return false;" />

<iframe id="iframe1" src="HtmlPage2.html"></iframe>

HtmlPage2.html:

<body>

<div style="border: 1px solid green; height: 1200px;">

</div>

</body>

Solution: You can choose either approach:

Set the ReloadOnShow property of the RadWindow to true.
Or use the following workaround to reset the iframe element dimensions:

function clientShow(sender, args) {

if ($telerik.isChrome) {

sender.get_contentFrame().style.width = "";

setTimeout(function () {

sender.get_contentFrame().style.width = "100%";

}, 0);

}

<telerik:RadWindow ID="RadWindow1" runat="server" NavigateUrl="HtmlPage2.html" OnClientShow="clientShow"></telerik:RadWindow>

rad grid export to word - not able to attach content at the end

I have a rad grid and I am trying to export to word. I have few issue with it

1. I am able to export the grid and would like to add some extra content at the end of the document. I have tried below code but the html is coming at the top of the document but I would like to get the content at the end of the document.

protected void alllGrid_Exporting(object sender, GridExportingArgs e)

{

if (e.ExportType == ExportType.Word)

{

// this is for trying orientation landscape

e.ExportOutput = e.ExportOutput.Replace("<body>", "<body><div class=WordSection1>");

e.ExportOutput = e.ExportOutput.Replace("</body>", "</div></body>");

string css = "<style> table @page{ mso-page-orientation:landscape;}</style>";

StringBuilder pageBrk = new StringBuilder();

// this is for page break

pageBrk.Append("<br clear='all' style='mso-special-character: line-break; page-break-before: always' />");

pageBrk.Append(css);

// this actual html content which is rendering properly but at the top of the page

var customHTML = AdHocFilterSummary().Append(pageBrk);

e.ExportOutput = e.ExportOutput.Replace("<body>", "<body>" + customHTML);

}

2. I am trying to do orientation as landscape but I am not able to make it work. I have used the below code given in one of the forums but couldn't make it work. Am I missing something here?

protected void alllGrid_HTMLExporting(object sender, GridHTMLExportingEventArgs e)

{

e.Styles.Append("th { text-align:center; font-color:green; }");

if (Response.ContentType.Contains("excel"))

{

e.Styles.Append("");

e.XmlOptions = "<xml><x:ExcelWorkbook>" +

"<x:ExcelWorksheets><x:ExcelWorksheet><x:WorksheetOptions>" +

"<x:Print><x:ValidPrinterInfo/></x:Print>" +

"</x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets>" +

"</x:ExcelWorkbook></xml>";

}

else

{

e.Styles.Append("<!-- @page WordSection1 { size: 297mm 210mm; margin:1.0in 2.0in 1.0in 2.0in; }" +

"div.WordSection1 {page:WordSection1;} -->");

}

3. I am trying to get the same thing on excel too. No matter what i do, I am not getting anything on Excel. I am using ExcelML format. Is there any special way to do it?

Thanks.
