[Solved] GridHyperLinkColumn - when user doesn't have permission to view URL I need OnItemCommand to fire when the cell is clicked?

Hi,

I have been Googling for a solution but I haven't found one. What I need to do is relatively simple I think. I am using a GridHyperLinkColumn. Sometimes the user will not have permission to view a particular link though.

So, in the code behind what I have at the moment is something like the code below. What I need to fill in is the what goes here ?????? bit. Is it possible to populate NavigateUrl with something that will make OnItemCommand fire in the normal way?

protected void OnItemDataBound(object sender, GridItemEventArgs e)

{

var gridDataItem = e.Item as GridDataItem;

if (gridDataItem != null)

{

var entity = gridDataItem.DataItem as MyEntity;

if (entity != null)

{

if (CanViewThisEntity)

{

var url = GetLinkForEntitySomehow();

var link = (HyperLink)gridDataItem["Name"].Controls[0];

if (!string.IsNullOrEmpty(url))

{

link.NavigateUrl = url;

}

else

{

what goes here ??????

}

My problem at the moment is that OnItemCommand will fire only if the cell is clicked somewhere outside the text of the anchor tag (because the anchor is being rendered without a link).Or is there a better way maybe. I hope I am making sense!

Thanks.

Unable to get value of properity id object is null or undefined.

I am have a user control in a parent page. The parent page has two RadGrids and the user control has one RadGrid. When an item is selected in one of the parent grids, the grid in the user control is updated. The UC grid uses batch editing, but both parent grid are read only. This all works, except a JavaScript error "Unable to get value of property 'id' object is null or undefined." which occurs in the Telerik.Web.UI.Grid.GridBatchEditingScripts.js file.

Between the two there are 4 files with lots of code. I would like to attach a zip file so that you can look at the code, but this forum will not allow it and because it seems to be a RadGrid JavaScipt error, I cannot isolate just where in the code the error is occurring. So I can't copy any code to this forum. Also there is no other JavaScript on the page or on the UC.

Does anyone have an idea of what might be causing this error or to at least give me some idea where to look?

Thanks,

~Sonny

RadComboBox, Firefox and page refreshing

Hi. Got an interesting issue here. I am performing a cascading drop down set of controls using comboboxes. If the browser is refreshed (either through F5 or the refresh button) in FF after the first combobox has made a selection, the first combobox will retain it's selection while IE11 and Chrome will reset to initial load settings. This example also uses RadAjaxManager and RadAjaxManagerProxy to simulate the real world problem I am having where the user control with the comboboxes is using the proxy object.
HTML:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="FF_Combobox_Test.aspx.cs" Inherits="testwebapplication.FF_Combobox_Test" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="scriptmanager" runat="server"></telerik:RadScriptManager>

<div>

<telerik:RadAjaxManager ID="ajaxmanager" runat="server"></telerik:RadAjaxManager>

<telerik:AjaxSetting AjaxControlID="FirstBox">

<telerik:AjaxUpdatedControl ControlID="SecondBox" />

</UpdatedControls>

</telerik:AjaxSetting>

</telerik:RadAjaxManagerProxy>

<telerik:RadComboBox ID="FirstBox" runat="server" AutoPostBack="true"

OnSelectedIndexChanged="FirstBox_SelectedIndexChanged" CausesValidation="false">

<telerik:RadComboBox ID="SecondBox" runat="server" EnableLoadOnDemand="true" EnableVirtualScrolling="true" AllowCustomText="true"

OnItemsRequested="RadComboBox1_ItemsRequested">

</telerik:RadComboBox>

</div>

</form>

</body>

</html>

Code-Behind:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace testwebapplication

{

public partial class FF_Combobox_Test : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (IsPostBack) return;

List<string> testlist = new List<string>();

testlist.Add("Americas");

testlist.Add("Asia");

testlist.Add("Europe");

FirstBox.DataSource = testlist;

FirstBox.DataBind();

}

protected void RadComboBox1_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

}

protected void RadComboBox1_ItemsRequested(object sender, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)

{

List<string> testlist;

switch (FirstBox.SelectedItem.Text)

{

case "Americas":

testlist = AmericasList();

break;

case "Asia":

testlist = AsiaList();

break;

case "Europe":

testlist = EuropeList();

break;

default:

testlist = new List<string>();

break;

}

foreach (string item in testlist)

{

SecondBox.Items.Add(new Telerik.Web.UI.RadComboBoxItem(item));

}

protected void FirstBox_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

SecondBox.Text = String.Empty;

SecondBox.DataBind();

}

private List<string> AmericasList()

{

List<string> test = new List<string>();

test.Add("AMERICA1");

test.Add("AMERICA2");

test.Add("AMERICA3");

return test;

}

private List<string> AsiaList()

{

List<string> test = new List<string>();

test.Add("ASIA1");

test.Add("ASIA2");

test.Add("ASIA3");

return test;

}

private List<string> EuropeList()

{

List<string> test = new List<string>();

test.Add("EUROPE1");

test.Add("EUROPE2");

test.Add("EUROPE3");

return test;

}

I should also note that after the page is refreshed, if the second combobox is opened, it will fire the first combobox's selectionchanged event.

Any clue what its doing, what I may be doing wrong and if this is a real bug?

Also, this is using v2013.2.611.45.

Thanks!
