Strange behaviour on toggle checkbox button with images

I use the following RadButton on a couple of pages and it behave strangely on each page.

<style type="text/css">

.rbBlue .rbText {

color: blue;

}

.rbRed .rbText {

color: red;

}

</style>

<telerik:RadButton ID="FillerNLF" runat="server" AutoPostBack="false" Text="NLF" ButtonType="ToggleButton" checked="false"

ToggleType="CheckBox" Style="font-size: 14px; top: 30px; left: 4px; position: absolute;">

<ToggleStates>

<telerik:RadButtonToggleState PrimaryIconUrl="../Images/layer_transparent.jpeg" CssClass="rbBlue" />

<telerik:RadButtonToggleState PrimaryIconCssClass="rbOk" Selected="true" CssClass="rbRed" />

</ToggleStates>

</telerik:RadButton>

On page 1, I use this and the behavior is fine. When the checkbox is unchecked, the text is blue colored and it is a transparent icon shown. When the checkbox is checked, the green checkmark appears and color of the text is red. That is the proper behavior.

When I use the exact same button on another page, I am getting a square outline of the layer_transparent.jpeg file when it is unchecked. If I hover the mouse over the item, the square outline disappears and nothing is displayed, except the blue text. When the checkbox is checked, a green checkbox appears and the text is red. So, it is the unchecked behavior that is not working. It's for this page only. I noticed this as I am building the page and there is no logic in the codebehind.

Reading read only column in ragdrid update

I am using EditMode="InPlace" and AllowMultiRowEdit="True" to edit a RadGrid. I am also using a non RadGrid button to save the RadGrid to a database. Column1 in the RadGrid is read only. I am using ExtractValuesFromItem(newValues, editedItem) to get the cell that was changed. This works, but I don't know how to reference the value in the read only cell in column1 to see which row was edited. I need this to update the database based on the read only information in Column1. I will also be adding databound dropdown lists in the EditItem template so a solution that drastically changes the code below also needs to be able to handle that.

protected void SaveButton_Click(object sender, EventArgs e)

{

foreach (GridItem item in RadGrid1.Items)

{

if (item.IsInEditMode)

{

GridEditableItem editedItem = (GridEditableItem)item;

Hashtable newValues = new Hashtable();

editedItem.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);

// I need to get the value in Column1 on the edited row.

string ReadOnlyCell = ["Column1"].toString();

string ChangedCell = newValues["Column2"].ToString();

// will update SQL here...

editedItem.Edit = false;

}

RadGrid1.Rebind();

}

Radgrid & IE10

Hi All:

We have a rather large project where we are using RadGrid from Telerik 2011.1.519.35. We are having a problem with IE10 where the RadGrid will only resolve / appear to about half it's width (i.e., we have one-half of the grid appearing). IE10 then locks up.

We are not having this problem with any other browser (including earlier versions of IE). Unfortunately, while we use Chrome for internal users of our system, we cannot control what browser is used by external users.

We make heavy use of Telerik controls in our application and updating to a more recent version will require a large amount of recursion testing before we could roll out a new version of the dlls.

Is there any workaround to this, or is our only recourse to update to the latest version of Telerik?

Thanks for your help in this matter.

RadGrid inside ServerControl and LinkButton.Click ...

Good Afternoon,

I had the idea of including a RadGrid control inside a custom server control ( reusable on various sites ) and everything works just peachy apart the .Click event of a LinkButton in a TemplateColumn that I can't seem to intercept !

The layout is as follows:

aspx
asp:Panel
MyControl
telerik:RadGrid
MasterTableView
GridTemplateColumn
LinkButton

The LinkButton is created on fly during the RadGrid.ItemDataBound event and added to the columns control collection via:

Dim o_LineDeleteItem As New LinkButton With {.Text = "Del", .ID = String.Format("Delete|" & __Item.DataItem("slc_ID").ToString), .CommandName = "DeleteLineItem", .CommandArgument = __Item.DataItem("slc_ID").ToString}

__Item("Options").Controls.Add(o_LineDeleteItem)

I have tried with/without AddHandler and whatnot, can't seem to get it to work.

The Panel is ajaxified via a RadAjaxManagerProxy and has a RadAjaxLoadingPanel that correctly shows when I click the LinkButton in the grid ... but for some reason I am unable to either get the RadGrid.ItemCommand or LinkButton.Click event to fire to actually do something when the button was clicked.

I tried if many different ways, but this being my first such implementation I most certainly miss something ( more or less ) important.

Any clues on this ?

PS: I looked thru the documentation and searched the www ... to no avail.

there may be 2 conditions possible
1 ] IF logged in user is COMPANY ADMIN then the parent node=Company name and Child Nodes are employees from that company

and image is also given
2 ] IF logged in user is SUPER USER then he can view all company as parent names and the employees in that company name
image is given and also code

private void BindToDataTable(RadTreeView RadTreeView1)

{

RadTreeView1.DataSource = "";

RadTreeView1.DataBind();

int UserId = Convert.ToInt32(Session["UserId"].ToString());

int RoleId = Convert.ToInt32(Session["RoleId"].ToString());

Temp = objGlobas.BindTreeView_Test(UserId, RoleId);

//Get Permission to logged in user individually and by group and combine these Entities into one datatable dt2

Globas ObjGlobas = new Globas();

DataTable dtViewPermission = new DataTable();

dtViewPermission = ObjGlobas.ViewPermission(UserId);

DataTable RootNode = new DataTable();

RootNode = Temp;

DataView dView = new DataView(RootNode);

string[] arrColumns = { "CompName", "CompId" };

RootNode = dView.ToTable(true, arrColumns);

if (Convert.ToInt32(Session["RoleId"]) == 1)

{

DataTable dtchildnode = new DataTable();

if (Temp.Rows.Count > 0 && Temp != null)

{

foreach (DataRow row in RootNode.Rows)

{

RadTreeNode tnparent = null;

string ParentNode = row["CompName"].ToString().Trim();

string ParentID = row["CompId"].ToString().Trim();

tnparent = new RadTreeNode(ParentNode);

tnparent.Value = ParentID.ToString();

RadTreeView1.Nodes.Add(tnparent);

tnparent.AllowEdit = false;

tnparent.ContextMenuID = "contextMenu1";

int CompanyId = Convert.ToInt32(ParentID);

dtchildnode = ObjGlobas.BindTreeView_SuperUser(CompanyId);

foreach (DataRow dr in dtchildnode.Rows)

{

RadTreeNode Child = null;

string child = dr["EntityName"].ToString();

string EntityId = dr["EntityId"].ToString();

Child = new RadTreeNode(child);

Child.Value = EntityId;

tnparent.Nodes.Add(Child);

Child.ContextMenuID = "contextMenu2";

}

else

{

if (Temp.Rows.Count > 0 && Temp != null)

{

foreach (DataRow row in RootNode.Rows)

{

RadTreeNode tnparent = null;

string ParentNode = row["CompName"].ToString().Trim();

string ParentID = row["CompId"].ToString().Trim();

tnparent = new RadTreeNode(ParentNode);

tnparent.Value = ParentID.ToString();

RadTreeView1.Nodes.Add(tnparent);

tnparent.AllowEdit = false;

tnparent.ContextMenuID = "contextMenu1";

foreach (DataRow dr in dtViewPermission.Rows)

{

RadTreeNode Child = null;

string child = dr["EntityName"].ToString();

string EntityId = dr["EntityId"].ToString();

Child = new RadTreeNode(child);

Child.Value = EntityId;

tnparent.Nodes.Add(Child);

Child.ContextMenuID = "contextMenu2";

}

my problem is while SUPER USER login for each companys child node stored procedure is executing,is there any alternative way to do this.
Thanks

Problem with modal behavior

Hello,

I am displaying a RadWindow in modal form. Window displays fine but if I move window around and try to move it over a menu, then the menu is shown on the top, window gets below. Plus if I keep moving it then it goes under the address bar of the browser. After that there is no way to drag window back. See the screen shot attached .... Any suggestions?

Thanks in advance!
