I have not made a Ticket yet since I will begin by looking into general solutions.

The problem is simple. The grid just wont accept any updates from inline editing of the Grid. There seems to be some kind of Error that doesn't show up on normal Clients.

I have tried the Clear Cache solution but no go.

Any ideas on this? Btw, the same problem exists on your Demo Grid.

Timeout when calling ToDataSourceResult

I am receiving a timeout error via an AJAX call when using Kendo with MVC. The result set is a large set of records approx 250K with 14 fields though I would not expect this to timeout. Any ideas why this might be happening?

public ActionResult Grid_Read([DataSourceRequest]DataSourceRequest request)

{

var dbContext= new DataBaseContext();

IQueryable<Report> ReportData = from ParentRecord in ParentTable

join ChildRecord in ChildTable on ParentRecord.Id equals ChildRecord.ParentId

select new ReportModel

{

FieldOne = ParentRecord.FieldOne,

FieldTwo = ParentRecord.FieldTwo,

FieldThree = ChildRecord.FieldThree

};

DataSourceResult result = ReportData .ToDataSourceResult(request);

return Json(result);

}

[Solved] Read-only fields not being validated

Hello.
I just updated to the latest version of Kendo UI for ASP.NET MVC (Q3 2012).
I noticed that some text boxes with both "required" and "readonly" attributes are not being validated anymore.
Here's what I have:

@{
   var materialHtmlAttributes = new Dictionary<string, object>();
   materialHtmlAttributes.Add("class", "k-textbox");
   materialHtmlAttributes.Add("readonly", "readonly");
   materialHtmlAttributes.Add("data-bind", "value: item.Material.Description");
   materialHtmlAttributes.Add("validationMessage", "The Material field is required.");
   materialHtmlAttributes.Add("required", "required");
}
@Html.TextBox("materialInputText", null, materialHtmlAttributes)

With the previous version of Kendo UI, this worked fine and the field was validated correctly, even being read-only. Now, this does not work anymore, the field is no longer validated. If I remove the read-only attribute, then it works.
It is important that the field remains read-only, because the value is set according to a selection made by the user in a list.

Is there a reason for this to not work anymore? Do I have to make some adjustments?

Thank you.

How to specify custom editor inline for a column?

I want to display a custom dropdownlist for an editable column. I see raw query examples that set an editor property that calls some function but I couldn't figure out how to make this work with mvc. What other options do I have available that are inline within the same page as the grid?

Another example is for a lookup control. I want to display a readonly textbox with a ... button that will launch another modal lookup dialog.

I need a solution that is inline with the page and doesn't involve me customizing my business objects with uihints or adding partial pages just for a column editor.

Binding TreeView to a JSON-Result

Hello,

we are changing our application from Telerik Controls to Kendo UI. But changing the TreeView is a little bit difficult. I hope you can help me:

With Telerik we used the OnDataBinding- Event, called a controller-class and bound a json-result to our tree: tree.bindTo(jsonObject)
Well this isn't possible with KendoUI.

So I tried the DataSource-thing on our tree:

@(Html.Kendo().TreeView()

.Name("TreeView")

.DataTextField("Text")

.DataImageUrlField("ImageUrl")

.DataUrlField("Url")

.DataSource(dataSource => dataSource

.Read(read => read

.Action("GetTreeData", "Home")

)

.ExpandAll(true)

Without all these DataTextField, DataImage.. stuff nothing worked so after hours I found out that I need them (there has to be a better documentation... please). But: How can I add ChildElements? With hasChildren (as a Property on the Json-Object) Ithe TreeView knows that there are children but I also wanna show them after binding (.ExpandAll(true).... <-- wanna use it!)

I really hope you can help me. I want to bind the complete tree-structure at once. No Load on demand. Is there any solution for doing that?

And if I have my complete tree... how am I able to rebind it? We need to refresh the tree very often, so I hope you can show me a possibility to do that.

Thank you very much!
Mathias
