I am using a DropDownList in a Grid.    I have nullable fields using the DropDownList.   I am having a problem deleting items that have been selected in the DropDownList.    Here is an example.    We have a nullable field for DepartmentID in a table and we have entered and saved data using the DropDownList.   Now we want to delete the DepartmentID field (or make it null again).   I have tried using the {delete} key, but that does not work.   I have tried trying to capture the {delete} key on the KeyPress in JavaScript and manually change the DepartmentID, but the {delete} key gets trapped before getting to my JavaScript so I cannot do it from JavaScript.    How do you reset the DepartmentID field back to Null?

Thanks, Larry

Is it possible to change the title of a panel bar in jquery after the control has been created?
I want to enable a user to change the title of a panelbar.  The panel bar will be created, within the panelbar will be a textbox that the user can enter new title for the panelbar.

I have been programming for many years now, but I am new to the web development world.   Is it possible to call a Controller ActionResult (get) method from javascript?    I have a grid with a dropdownlist.  I have the grid setup to use the change event.   I have javascript for the onChange event.   In this javascript I would like to make a call to a controller to retrieve information based upon the selection that was just made with the dropdownlist.   Is this possible?

Hi,

I want to know is there any way to set group column by clicking on any other check box on same page outside the grid.

<div id="grid"></div>
<input type="checkbox" id="chkOrderGroup" />

//script

$("#grid").kendoGrid({
  columns: [
    { field: "name" },
    { field: "age",
      groupFooterTemplate: "Total: #= count #"
    }
  ],
  dataSource: {
    data: [
      { name: "Jane Doe", age: 30 },
      { name: "John Doe", age: 30 }
    ]
  }
});
  $(document).ready(function () {
      $('#chkOrderGroup:checkbox').change(function () {
            var g = $("#grid").data("kendoGrid")
            var objGroup = g.dataSource.group;
         // *******************************  Require code to set  column with name  "age"  as group column when check box is checked *****
      });

Require code to set  column with name  "age"  as group column when check box is checked.

We are trying to render a NumericTextBox in a Kendo grid. But the trick to lookup the id with javascript is not working. Can anyone help?

My code:
MVC View:
            @(Html.Kendo().Grid(Model.BeginVoorraadModel.Rows)
            .Name("Begingrid")
            .Columns(columns =>
            {
                columns.Bound(p => p.Totaalgewicht).Title("Totaalgewicht<br/>(kg)").ClientTemplate(
                    Html.Kendo().NumericTextBox()
                    .Name("BeginVoorraadModel.Rows[#= index('Begingrid', data)#].Totaalgewicht")   <== here is the problem!
                    .Culture("nl-NL")
                    .Decimals(2)
                    .HtmlAttributes(new Dictionary<string, object> { { "value", "#=Totaalgewicht#" }, { "class", "numTextBox" } })
                    .ToClientTemplate().ToHtmlString());

                columns.Bound(p => p.Omschrijving).Title("Omschrijving");
                columns.Bound(p => p.Stikstof);
                columns.Bound(p => p.Ureum);
                columns.Bound(p => p.Fosfaat);
                columns.Command(c => { c.Custom("Del").Click("onRemove"); });
            })
            .ToolBar(toolbar =>
            {
                toolbar.Create().Text("Toevoegen");
            })
            .Editable(edit => { edit.Mode(GridEditMode.InCell); edit.CreateAt(GridInsertRowPosition.Bottom); })
            .Resizable(resizing => resizing.Columns(true))
            .DataSource(dataSource => dataSource
            .Ajax()
            .Batch(false)
                .Model(model =>
                {
                    model.Id(p => p.Id);
                    model.Field(p => p.Totaalgewicht).Editable(false);
                })
                .Read(r => r.Action("ReadBeginVoorraad", "Kunstmest"))
                .Destroy(r => r.Action("DeleteBeginVoorraad","Kunstmest"))
            ) 

Javascript:
function index(grid, dataItem) {
    var data = $('#' + grid).data("kendoGrid").dataSource.data();

    return data.indexOf(dataItem);
}

Thnx!

Dear Telerik Support Team,

I would like to know if it is possible to batch delete and update of selected rows by the external buttons. 
If yes, Could you please provide the sample code?  

Scenario is

I have a multiple rows selectable grid, "Delete Selected Items" button and "Assign DataOwner" button in my View.

If User click on "Delete Selected Items" button then the selected rows will get deleted
If User click on "Assign DataOwner" button then the selected rows Owner column will get updated as DataOwner. 

I'm getting an javascript error when trying to filter the scheduler using a Guid from a dropdownlist.  I had a very similar error when filtering by an int.  That was fixed by using parseInt(this.value)  instead of using this.value and then assigning the parseInt to  the filter value like:
Now I'm having the same type of error when the DataValueField of the dropdownlist is a Guid.

I'm doing this:

I placed a break point in the code and 'selection' is a valid guid string and it is the guid that I expected it to be.
Can you filter by a Guid?

In your examples,i noticed that the column has a big width,but when editing the column,the texbox is much smaller,so it doesn't rich the end of column limits.how can i do that?

Regards,
Daniel

Hi All,

Does anyone know if it's possible to check/uncheck the check box elements of the ColumnMenu in the kendo grid from the onDataBound event.
I have a specific requirement when I can't use the columnHide() 

Any help would be greatly appreciated.

Cheers,
Michael

Hy,

I have implemented js code to expand all child items under the selected NODE item.   And This Works FINE.

Is there a build in way in KEDO Treeview do this ? a better way...I mean.


OnRClickTreeNode()
{
var node = getTreeView().findByUid(getRightClickedItem().uid);
var treeView = getTreeView();
expandNodeChildItemsRecursive(treeView, node);
}

function expandNodeChildItemsRecursive(treeView, node) {
treeView.expand(node);
var childNodes = $(".k-item", node);
for (var i = 0; i < childNodes.length; i++) {
expandNodeChildItemsRecursive(treeView, childNodes[i]);
}
}
