Questions on UI for ASP.NET AJAX Forum

Sorry to sound impatient (I may yet have to open a support ticket) but I've been testing my application and I've run into a last minute IE11 compatibility problem.

I have a RadGrid that uses RadButtons as link buttons to download attached files from a database. This general set up has been in production for years now and has generally worked perfectly, in Chrome and Firefox. Unfortunately we've had a number of problems with IE and we had believed we had solved most of them by moving to a new server and this generally seems to be true, with one exception.

I cannot download files in IE. I get an error message saying file cannot be downloaded. If I retry it claims to have succeeded but what I get is a corrupted stub of a file.

The download process itself runs through the RadGrid's ItemCommand event handler and is so far as I know fairly conventional. I get the file as a string from the database, set the Current.Response.ContentType to whatever the file is (In this case "image/jepg"), then do an add header ( AddHeader("Content-Disposition", "attachment; filename=\"" + sAttachName + "\"") ) and finally a BinaryWrite of the byte array containing the file. As I said, this works perfectly in Chrome and Firefox.

It occurs to me that I've already had a problem like this earlier (http://www.telerik.com/forums/failure-of-download-links-after-ajaxifying-radgrid) and the code mentioned in that entry has not been changed in any way.

Suggestions?

RadAsyncUpload with DisablePlugins="true"

<telerik:RadAsyncUpload runat="server" DisablePlugins="true" EnableInlineProgress="false" ID="AsyncUpload1" OnClientFileUploaded="OnClientFilesUploaded"
UploadedFilesRendering="BelowFileInput" MultipleFileSelection="Automatic" />

<telerik:RadButton ID="btnUploadFiles" OnClientClicking="OnClientClicking" runat="server" Text="Upload File" />

when DisablePlugins="true" of RadAsyncUpload, we can not select multiple files on IE

and if we remove DisablePlugins="true" of RadAsyncUpload, $telerik.$(".ruFileInput").click(); event not working...

Mouse Over Telerik Calendar Throws Off Page Layout

We have a page which has a div at the top with some links and a Telerik Calendar control. Below we have a large grid of divs in a layout mimicking a spreadsheet.

When the page loads for the first time everything works fine. Then when you click on the "More" button, the js makes a remote scripting call back to the server to get more rows for our scrolling spreadsheet. The page returns and fills the divs associated with the "spreadsheet" with the updated data. The problem is that now when the user mouses over the calendar, the whole div that contains the calendar jumps down 3 lines or so. When debugging the page, I've noticed that the call that seems to be throwing off the alignment is the call to the following code.

Is there any way stop the code I've pasted below from firing when mousing over the calendar control or else to stop this code from disrupting the layout of the divs on an update the the divs in the DOM?

Sys.UI.DomEvent = function Sys$UI$DomEvent(eventObject) {

/// <summary locid="M:J#Sys.UI.DomEvent.#ctor" />

/// <param name="eventObject"></param>

/// <field name="altKey" type="Boolean" locid="F:J#Sys.UI.DomEvent.altKey"></field>

/// <field name="button" type="Sys.UI.MouseButton" locid="F:J#Sys.UI.DomEvent.button"></field>

/// <field name="charCode" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.charCode"></field>

/// <field name="clientX" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.clientX"></field>

/// <field name="clientY" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.clientY"></field>

/// <field name="ctrlKey" type="Boolean" locid="F:J#Sys.UI.DomEvent.ctrlKey"></field>

/// <field name="keyCode" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.keyCode"></field>

/// <field name="offsetX" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.offsetX"></field>

/// <field name="offsetY" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.offsetY"></field>

/// <field name="screenX" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.screenX"></field>

/// <field name="screenY" type="Number" integer="true" locid="F:J#Sys.UI.DomEvent.screenY"></field>

/// <field name="shiftKey" type="Boolean" locid="F:J#Sys.UI.DomEvent.shiftKey"></field>

/// <field name="target" locid="F:J#Sys.UI.DomEvent.target"></field>

/// <field name="type" type="String" locid="F:J#Sys.UI.DomEvent.type"></field>

var e = Function._validateParams(arguments, [

{name: "eventObject"}

]);

if (e) throw e;

var ev = eventObject;

var etype = this.type = ev.type.toLowerCase();

this.rawEvent = ev;

this.altKey = ev.altKey;

if (typeof(ev.button) !== 'undefined') {

this.button = (typeof(ev.which) !== 'undefined') ? ev.button :

(ev.button === 4) ? Sys.UI.MouseButton.middleButton :

(ev.button === 2) ? Sys.UI.MouseButton.rightButton :

Sys.UI.MouseButton.leftButton;

}

if (etype === 'keypress') {

this.charCode = ev.charCode || ev.keyCode;

}

else if (ev.keyCode && (ev.keyCode === 46)) {

this.keyCode = 127;

}

else {

this.keyCode = ev.keyCode;

}

this.clientX = ev.clientX;

this.clientY = ev.clientY;

this.ctrlKey = ev.ctrlKey;

this.target = ev.target ? ev.target : ev.srcElement;

if (!etype.startsWith('key')) {

if ((typeof(ev.offsetX) !== 'undefined') && (typeof(ev.offsetY) !== 'undefined')) {

this.offsetX = ev.offsetX;

this.offsetY = ev.offsetY;

}

else if (this.target && (this.target.nodeType !== 3) && (typeof(ev.clientX) === 'number')) {

var loc = Sys.UI.DomElement.getLocation(this.target);

var w = Sys.UI.DomElement._getWindow(this.target);

this.offsetX = (w.pageXOffset || 0) + ev.clientX - loc.x;

this.offsetY = (w.pageYOffset || 0) + ev.clientY - loc.y;

}

this.screenX = ev.screenX;

this.screenY = ev.screenY;

this.shiftKey = ev.shiftKey;

}

I've been wrestling with this for several day now, so any thoughts or ideas are much appreciated!

Filter on comma-delimited/multiple values on a Grid Column

Scenario: Users want to be able to specify a comma delimited-set of values to search for.

Solution: Convert "EqualsTo" query with a comma to a "IN { 'a','b','c' }" list style query. Bit hackish.

I'm using the sample in the Forum post as the base (it allows me to have a pre-specified/default filter and then add to it): http://www.telerik.com/forums/grid-filter-and-the-entitydatasource-control-whereparameters

Use a standard (or in my case Calculated) column, but with the field defined, with standard "EqualsTo" field defined:

<telerik:GridTemplateColumn DataField="CustomerTypeCode" UniqueName="CustomerType" HeaderText="Customer Type" SortExpression="CustomerTypeCode" CurrentFilterFunction="EqualTo" AutoPostBackOnFilter="true" ShowFilterIcon="false" FilterControlWidth="130px">

<HeaderStyle Width="150px" />

<ItemStyle Width="150px" />

<ItemTemplate>

<%# string.Format("{0} - {1}", Eval("CustomerTypeCode"), Eval("CustomerTypeDescription")) %>

</ItemTemplate>

</telerik:GridTemplateColumn>

You "Selecting" event on the Entity Data Source is handled as per above sample:

protected void edsCustomers_Selecting(object sender, EntityDataSourceSelectingEventArgs e)

{

// Get the filtered data source (if applicable) and then append/pre-pend default filter

EntityDataSource dataSource = e.DataSource;

AddParameters(dataSource);

BuildWhere(dataSource);

}

Here's the crazy hack to rewrite the EqualsTo / Contains (LIKE) to a "IN" clause style query:

private void BuildWhere(IDynamicDataSource dataSource)

{

string filter = FilterDefault;

// Parse filters with commas - convert LIKE and Equals (=) queries to IN query

string gridFilters = dataSource.Where;

if (!string.IsNullOrEmpty(gridFilters))

{

if (gridFilters.Contains(","))

{

// Find filter fields (either Equals = or LIKE) with data inside quotes and rewrite to an "IN" query

// Looks for it.[Field] = "a,b" (or it.[Field] LIKE "%a,b%") etc

Regex regexCommaValues = new Regex("it\\.\\w*.....\\s([\"'])(?:(?=(\\\\?))\\2.)*?\\1");

var matches = regexCommaValues.Matches(gridFilters);

foreach (Match match in matches)

{

string value = match.Value;

value = value.Replace("LIKE \"", "IN {'");

value= value.Replace("%", "");

value = value.Replace("= \"", "IN {'");

value= value.Replace(",", "','");

value= value.Replace("\"", "'}");

// Replace original match with modified string

gridFilters = gridFilters.Replace(match.Value, value);

}

filter += " AND " + gridFilters;

}

// If custom filtering enabled, pre-pend with our default parameter

dataSource.Where = filter;

}

Enjoy the hack.

Please - if you can improve the solution or the regex, let me know!

javascript $find("<%= RadGrid1.ClientID %>") returns null on the webserver

Hi,

When testing my code on my development box, I am attempting to find a radgrid in javascript (on the client) using the command:

$find("<%= RadGrid1.ClientID %>")

This returns an object and I have no problems.

When I deploy my code to our web server, this returns a null. My question is whether the web server needs to have a Telerik license installed or can the binaries be deployed and the code should work.

The current deployed binaries are:
Telerik.Web.UI.XML
Telerik.Web.Device.Detection.xml
Telerik.Web.Design.dll
Telerik.Web.Device.Detection.dll
Telerik.Web.UI.dll
Telerik.Web.UI.Skins.dll

Thanks,

RadChart shrinks inside RadTab

We have 3 tab RadTabStrip and each of the tab has radtabs. We have radchart inside these tabs.

The chart gets loaded correctly onload. But it gets shrinked when i move from one tab to other.

I have noticed that 'd' attribute in 'path' element inside the 'g' element('svg') of radchart gets changed on moving from tabs to tabs.

Radgrid with print, copy, export etc. capabillity

Hi all,

I have a number of grids in my project(s). In many cases it is neccessary/helpful for users to

print the grids' content
copy to clipbord (for further analysis in e.g. Excel)
export data to a Excel readable file or PDF

I have set my sights on creating a user control containing a Radgrid (of course) and a toolbar of some sort which buttons can be enabled/disabled as needed (see attached mock-up picture where the toolbar replaces a pager's fuctionality plus has some tools). I have the feeling that this feature can be valuable to many users as it would provide a uniform approach to these common tasks.

I have be searching the forum for ideas and code snippets for my (dream) user control and I am stuck at the first stage. The print instructions in http://www.telerik.com/community/code-library/aspnet-ajax/grid/print-radgrid-contents.aspx do not work right out of the box (with or without skins).

I suspect that I am not the first one to have abovementioned need. Perhaps this functionality can already be found in some code library I have not stumbled on yet. But anyway... please point out to me the resources (complete code, snippets, problems) and might help me realize my user control.

Thank you!

tooltip rollover does not be updated to content for showing

Hi All,

I am facing a problem with tooltip, that the rollover keeps showing and does not be updated to the content. I can see the response contains the html code of the content ready for showing, but the rollover keeps showing and does not be changed to the html content.

I am using the version 3.5.0.0. and here is the settings:

<telerik:RadToolTipManager runat="server" AnimationDuration="150" ShowDelay="200" OnClientResponseError="OnClientResponseError"<br> HideDelay="10" HideEvent="LeaveToolTip" Position="TopCenter" RenderMode="Classic" ID="radTooltipMgr" Width="660px" Height="390px" RelativeTo="Element"<br> Animation="Fade" OnAjaxUpdate="OnAjaxUpdate" EnableDataCaching="True" AutoCloseDelay="0" RenderInPageRoot="True" Skin="BlackMetroTouch"><br></telerik:RadToolTipManager>

Does someone have the same problem with me?

Thanks for any suggestion!
