I have been looking at this example, but it appears as though it is calling methods not available in 10.3. Specifically, I am getting an error on the grid._applyClientBinding() line. Is there an updated version or hotfix that has these methods for the WebDataGrid?

Hi,

I tried $(grid.tableTemplate).render(newData).appendTo(grid._elements.dataTbl.lastChild); but it's throwing an exception. Object doesn't support this property or method. I am using JQuery 1.4.2, so should I be using a more newer version?

Dave

Hey Will,

What version of jQuery are you using? I can't seem to get mine to display the rows, even though I'm doing the exact same thing as you. Well almost. I'm send inding an ID to a WCF Web Service and it's returning a JSON sting. I get those objects out of the string and push them into another array, then use that is my datasource, but still it's empty. I'm using jquery-1.4.2.

Any ideas?

Dave

Hello Dave,

Make sure you have the template script also.

<script type="text/javascript" src="Scripts/jquery-1.4.2.js"></script>
<script type="text/javascript" src="Scripts/jquery.tmpl.js"></script>

it will fail if you do not initialize the template:

  if (!grdDonors.tableTemplate)
            grdDonors.tableTemplate = grdDonors._elements.dataTbl.lastChild.cloneNode(true);

I am doing basically the same as you. This was a stripped down version to show the problem. I am returning json from a webmethod and it is working and loading but can not interact with the grid once it is loaded. I just did a local var json to show the problem after load.

<WebMethod(EnableSession:=True)> _
<Script.Services.ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json)> _
  Public Shared Function DonorsByName(ByVal LastName As String, ByVal FirstName As String)

The concept is awesome

Hi Will,

Thanks for the info but I'm still having issues. I think the problem might be that I'm using 3.5 and not 4.0 like you are. When I call the _applyClientBinding() I get a JavaScript error because the render method is not there so I think there is more to this problem than we know. I tried a few other things and managed to get my rows to show up, but they're all blank. I've spent so much time on this that I can't waste anymore on it which is a real shame because, like you say, it's an awesome concept and lightening fast if it works.

One thing is for sure and that is my WCF code works perfectly as I can see the JSON string coming back from it and all the Objects when it's parsed. It's a real shame that I don't have the time to figure out the Grid rendering. I have to settle for an ugly PostBack.

Time is money and I can't be wasting anymore time...

Thanks
Dave

Looks like we are in the same boat so I will play around with it some more this week and hopfully an Infragistics developer will see this posting before too long and help us out.

Hi Dave

I tried as you suggested but still not getting

                var myGrid1 = $find("MainContent_pnlProjectDirectory_grdProjectDirectory");
                //create a datasource
                var dataSource = myGrid1._get_dataSource();
                var newData = eval(this.Data.lstProjectDir);

                //Empty the grid
                $(myGrid1._elements.dataTbl.lastChild).empty();

                //Populate the dataGrid
                myGrid1._pi.show(myGrid1);

                for (var i = 0; i < newData.length; i++) {
                    //dataSource.push(newData[i]);
                    $(myGrid1.tableTemplate).data(newData[i]).appendTo(myGrid1._elements.dataTbl.lastChild);
                }
                //myGrid1._set_dataSource(dataSource);
                myGrid1._pi.hide(myGrid1);

Now result is coming as but data is not displayed

<tr>
<td style="width: 0px;">${Id}</td>
<td style="width: 200px;">${Name}</td>
<td style="width: 200px;">${DisplayName}</td>
<td style="width: 120px;">${Phone}</td>

<td style="width: 120px;">${Fax}</td>
<td style="width: 120px;">${BusinessEmail}</td></tr>

But one more point when I am pushing data to datasource and applyingClientBinding it is giving error
for (var i = 0; i < newData.length; i++) {
                   dataSource.push(newData[i]);
                    $(myGrid1.tableTemplate).data(newData[i]).appendTo(myGrid1._elements.dataTbl.lastChild);
                }
                myGrid1._set_dataSource(dataSource);
                myGrid1._applyClientBinding();
                myGrid1._pi.hide(myGrid1);

When not pushing data to datasource it is not giving any error of object does not support

Hi Shyam,

I don't work for Infragistics but would like to try helping you out, at the same time fixing my own issue. I might have the time during the backend of this week but from what I can see in your code example all looks good. Are you seeing blank rows of data or not rows at all?

This is what I tried so it might help you. It DOES NOT use dataGrid._applyClientBinding(); because jQuery would always through that same error to are seeing. But this returns blank rows for me.

Let me know if this helps at all...Dave

Hi Dave
I am using .NET 4.0, Infragistics4.Web.v10.3, Version=10.3.20103.2105 and I am working in MVC.

I have a webdropdown on change of webdropdown on clientside (<ClientEvents SelectionChanged="wcProject_SelectionChanged" />) I am able to fetch data using JSON , JSONResult, now I want to bind that data to Webdatagrid
like -

//to bind webdatagrid
                var myGrid = $find('<%=grdProjectDirectory.ClientID %>'); //document.getElementById('');

                var dataSource = myGrid._get_dataSource();
                var arr = this.Inbox[0].lstProject;
                if (!myGrid.tableTemplate)
                    myGrid.tableTemplate = myGrid._elements.dataTbl.lastChild.cloneNode(true);

                for (var i = 0; i < arr.length; i++) {
                    dataSource.push(this.Inbox[0].lstProject[i]);
                }

                $(myGrid._elements.dataTbl.lastChild).empty();

                myGrid._set_dataSource(dataSource);
                myGrid._pi.show(myGrid);               

                myGrid._applyClientBinding();
                myGrid._pi.hide(myGrid);

Here on _applyClientBinding(); getting an error Object does not support this property or method

<script src="../../Scripts/jquery-1.6.1.js" type="text/javascript"></script>

<script src="../../Scripts/jquery.tmpl.js" type="text/javascript"></script>
  
    <script src="../../Scripts/jquery.tmpl.min.js" type="text/javascript"></script>
    <script src="../../Scripts/jquery.tmplPlus.js" type="text/javascript"></script>
    <script src="../../Scripts/jquery.tmplPlus.min.js" type="text/javascript"></script>

Suggest me where I am wrong.

Regards

Shyam

Hey Shyam,

Will and I talked about a solution a few weeks ago but lost contact for a bit due to working so damned much. Nevertheless, I can tell that Will got his solution working in .NET 4.0, but I was not able to get it working in .NET 3.5 as I don't think this feature is supported in that version. I need to reconnect with Will to see if his solution will work for me.

In the mean time can you fill me in on your specific situation? Like .NET version and Service Type, such as Web Service or WCF etc.

Thanks
Dave
