RadGridNamespace is not defined - Only on local computer

Well, I left work last night and everything was fine. Came back and I started getting the "RadGridNamespace is not defined" error, and my data was exploded all over the screen. I didn't make any changes, and I even rolled back my code to a version we were using over a week ago, and the same thing is happening.

The grid works fine on all of our servers, and works for our other developers, just not me.

Any ideas?

How to: Attach an event to a GridDropDownColumn

Hi all,

I have a control that inherits the Telerik.Web.UI.GridDropDownColumn like:

                             
                [DefaultProperty("Value")]         
                [ToolboxData("<{0}:myGridDropDownColumn runat=server></{0}: myGridDropDownColumn>")]         
                public class myGridDropDownColumn : GridDropDownColumn         
                { ... }        

I need to attach an event to fire up on Selected Value is changed. How can I accomplish this?

my control does not give me the OnColumnChange Event [url: http://www.telerik.com/help/aspnet-ajax/telerik.web.ui-telerik.web.ui.griddropdowncolumn_members.html] (am I missing something?)

and there is no Attribute propertie to attach a javascript call like:

myGridDropDownColumn myDrop = new myGridDropDownColumn();
myDrop.Attributes.Add("onchange", "alert('event fired!');");

My objective in this case is to create a dropDown that, when the selectedValue changes, it would populate the other DropDown in the same row: row[ x ].column[ 2 ], any idea is there is a tutorial about this technique... I can't find it anywhere around :(

LoadRtfContent and FormView

I put a RadEditor inside a Formview, which is inside a RadAjaxPanel. I use the following to load RTF:

protected void Unnamed_DataBinding(object sender, EventArgs e)

{
var txt = sender as RadEditor;

txt.LoadRtfContent(@"{\rtf1\ansi\deff0
{\colortbl;\red0\green0\blue0;\red255\green0\blue0;}
This line is the default color\line
\cf2
This line is red\line
\cf1
This line is the default color
}
");
}

The issue is the editor is displaying the text with HTML tags instead of formatted text. I am wondering if this is an issue with the trial version (still waiting for my company to process the purchase) since it adds warning text to the content automatically.

Sum up cells in RadGrid

Hi,

I've been having problems with client side calculations for my RadGrid (EditMode="Batch", EditType="Cell").

In order to sum up cells 'a' and 'b' and display the result in cell 'c' of the selected row (and only this row) I subscribed to OnBatchEditCellValueChanged event and created javascript function (see below).

It worked fine in 2014.403.45.

When switching to the latest (2014.2.618.40) and changing to EditType="Row" (it doesn't work for "Cell" also) all of a sudden I get loads of undefined/null object errors:

Error: Unable to get value of the property 'getElementsByTagName': object is null or undefined

Callstack:
_getDataControl
_openCellInEditMode
openRowForEdit
_open
_openEditFromEvent
Anonymous Function
>

I've spent hours researching this and still didn't manage to get this working...

I guess my question would be: could you please provide an example of a simple javascript function example that sums two cells and display the result in the third
cell of the selected row in RadGrid with EditMode="Batch", EditType="Cell".

Thank you in advance.

function BatchCellModified(sender, args) {

var grid = $find('<%= myGrid.ClientID %>');

var masterTable = grid.get_masterTableView();

var rows = masterTable.get_dataItems();

var rowArgs = args.get_row();

var rowIndex = rowArgs.sectionRowIndex;

var row = rows[rowIndex];

var txtTotal = row.get_cell("Total");

if (args.get_columnUniqueName() === "PD" ||

args.get_columnUniqueName() === "BI") {

var txtPd = (isNaN(parseFloat(row.get_cell("PD").outerText))) ? 0 : parseFloat(row.get_cell("PD").outerText);

var txtBi = (isNaN(parseFloat(row.get_cell("BI").outerText))) ? 0 : parseFloat(row.get_cell("BI").outerText);

var totalAmount = txtPd + txtBi;

txtTotal.innerHTML = totalAmount;

}

if (args.get_columnUniqueName() === "Total") {

if (txtTotal != (txtPd + txtBi)) {

var txtPdOutput = row.get_cell("PD");

txtPdOutput.innerHTML = 0;

var txtBiOutput = row.get_cell("BI");

txtBiOutput.innerHTML = 0;

}

};

Fill radwindow with row information from radgrid

Right now I have a radcontext menu in my radgrid that has Replace, Edit and Delete options. When delete is clicked, it opens a RadWindow. I have a radtextbox and a raddatepicker that need to fill the corresponding data from the radgrid upon Page_Load. Can anyone help? My issue is not knowing how to pull that data from the Default page.

Multiple RadGrid on same page, GridEditCommandColumn PerformInsert mode requiredfield validators Issue

We have similar two radgrids like below in one page. When we try to insert empty data clicking on insert it shows requiredfiled validator which is correct but it triggers requiredfield validator of 2nd grid also because it is also in edit mode. How to keep it separate so that validation for one grid should not call validation for 2nd grid if both are in edit/Insert mode.
