Hi,

As we are working on RAD DIAGRAM and we are trying to customise. Our requirement is to show the designed diagram even after zoom in and zoom out but in the existing one once we zoom in and try to zoom out the designed diagram is going out of the RAD DIAGRAM window. So can you please suggest us to resolve this issue asap.

Thanks & Regards

Hi,

RadDiagram is really nice component. I am trying to adapt this control to my project. After binding components using server-side methods, it worked fine. However I couldn't get edited shapes new properties (new title,X,Y). ShapesCollection has initial shapes. Is there any way that we can get the latest state of shapes at the server side.

Thanks.

Hello,

The changes that you make on the RadDiagram control are saved only on the client, so it is expected that the ShapesCollection will have the initial shapes.

There is an option for exporting the diagram data as shown in the following demo: http://demos.telerik.com/aspnet-ajax/diagram/examples/saveload/defaultcs.aspx. Nevertheless, currently it has a bug with getting the information for modified connections. You could use the following bug item in our feedback portal to track the status of the issue, vote for it and comment it: http://feedback.telerik.com/Project/108/Feedback/Details/139644

Hi Slav,
I am creating a raddigram as in this link "http://docs.telerik.com/devtools/aspnet-ajax/controls/diagram/functionality/shape-templates"
but i am not using DiagramShape. i am able to get the data as shown in the picture pic1.
later i am calling a function to check the value has been increased or not, if value increased i have to update the value. only value should be updated, i should not redraw whole shape. can i do that? if so how?
Please help me in this context.
in timer i am doing in this way but not able to update.
aspx:
<telerik:RadDiagram runat="server" ID="theDiagram" width="1330" RenderMode="Auto">
<ClientEvents OnClick="OnClick" />
<ShapeDefaultsSettings Visual="ImageTemplate"></ShapeDefaultsSettings>
</telerik:RadDiagram>
ImageTemplate:
function ImageTemplate(options) {
var dataviz = kendo.dataviz;
var group = new dataviz.diagram.Group({ autoSize: true });
var backGID = options.id;
if (backGID != "s1") {
group.append(new dataviz.diagram.Rectangle({
x: 0,
y: 0,
width: options.width,
height: options.height,
width: 195,
height: 75,
border_radius: 5,
background: "webkit-linear-gradient(top, #bed2e2 0%,#abd3ee 94%,#d5ebfb 100%)",
fill: {
color: "#bed2e2"

}
}));

var textWrap1 = options.content.substring(0, 12);
var textWrap2 = options.content.substring(12, 19);
group.append(new dataviz.diagram.TextBlock({
text: textWrap1,
color: "#000000",
x: 70,
y: 10
}));

if (textWrap2 != "") {
group.append(new dataviz.diagram.TextBlock({
text: textWrap2,
color: "#000000",
x: 70,
y: 25
}));
}

var img = options.content;
if (img.indexOf("ead") != -1) {
img = "../Images/Img_HeadCount.png";
group.append(new dataviz.diagram.TextBlock({
text: options.Counter,
color: "#FF0000",
x: 100,
y: 45
}));
}
else if (img.indexOf("oll") != -1) {
img = "../Images/Img_Rollcall.png";
group.append(new dataviz.diagram.TextBlock({
text: options.Counter,
color: "#FF0000",
x: 100,
y: 45
}));

}
else {
img = "../Images/Img_Assembly_Point.png";
group.append(new dataviz.diagram.TextBlock({
text: options.Counter,
color: "#FF0000",
x: 100,
y: 45
}));
}
var image = new dataviz.diagram.Image({
source: img,
x: 5,
y: 5,
width: 60,
height: 60,
});
group.append(image);
}
else {
var jsonFilename = '<%=backImageUpload%>';
if (jsonFilename == null || jsonFilename == "") {
var imageFolder = "../backgroundImage/backgound.jpg";
}
else {
var imageFolder = "../backgroundImage/" + jsonFilename + ".jpg";
}

var wid = dataviz.DEFAULT_WIDTH;
var image = new dataviz.diagram.Image({
source: "../backgroundImage/" + options.content + ".jpg",
x: 10,
y: 7,
width: wid + 550,
height: 400 + 200,
});
group.append(image);
}
return group;
};
timer function:
function CountDownTimer() {
$.ajax({
type: "POST",
url: "Frm_MusteringMonitor.aspx/GetSessionValue",
contentType: "application/json;",
data: JSON.stringify(),
success: function (Data) {
if (Data.d != "") {
var diagramWidget1 = $find("<%= theDiagram.ClientID %>").kendoWidget;
var listOfObject = JSON.parse(Data.d);
var dectionaryItem = Data.d.replace(/[&\/\\#+()$~%.'"*?<>{}]/g, '');
var getVal = dectionaryItem.split(',');
var leng = diagramWidget1.shapes.length;
var i = 1;
for (i = 1; i < leng; i++) {
var jsonObjName = getVal[i - 1].split(":");
var DiaObjname = diagramWidget1.shapes[i].options.content;
if (jsonObjName[0] === DiaObjname) {
var NewValue = jsonObjName[1];
diagramWidget1.shapes[i].options.Counter = NewValue ;
// i have three shapes so doing loop here and i am able to get the value here but not updating on diagram
}
}
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
}
});
}
Thanks in advance.

Hello Bhavya,

You can redraw the visual of the shape to show the new value. I have attached a short sample that demonstrates this approach.

Hello Bhavya,

You can create an Image object in the visual as shown in the following help article: http://docs.telerik.com/devtools/aspnet-ajax/controls/diagram/functionality/shape-templates

Then you can pass the path of the new image via the options of the shape and redraw its visual similarly to how I update the content in my previous sample.
