I need to have a status dropdown in each row of my RadGrid. This is something I want displayed and functional at all times, not just in edit mode. What I've done so far is use a template column with a dropdownlist inside, hard-coding the 3 status options. On the radgrid_ItemDataBound I grab the data row and set the selected value of the dropdown based on the data from the server. Now I need to fire and update when the dropdown is changed. I can point the dropdownlist to fire a Public Sub from the OnSelectedIndexChanged property but I need to it pass another value from the datarow. My first thought was to programmatically add in the status items w/ a unique id pulled from the database attached as the corresponding value but for some reason, it no longer fires the OnSelectedIndexChanged event.

Any ideas on how this can be achieved?

Horizontal Scroll not located at bottom of GRID

I have a RadGrid that has the following clientSettings.

<ClientSettings>

<Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="700" EnableVirtualScrollPaging="false" SaveScrollPosition="false" />

</ClientSettings>

So I want the vertical scroll to appear when the Grid grows past the 700 height I have specified in the scrollHeight. This works fine. The problem I'm running into is that the horizontal scrollbar is always appearing at the location of the max scrollHeight (700). So If my grid has 2 rows the horizontal scroll is way down the page and there is a bunch of white space filling in the space between the bottom of the 2nd row and the actual Horizontal scroll bar.

Any help or ideas would be appreciated. If you need more code I can paste more but the issue seems pretty clear and I was hoping for a fairly simple fix.

Thanks,

Julian

Bubble Charts - Negative Values in X-Axis and Multiple Bubble Colors

Its plotted in the positive quadrant (Refer Attached Images : ExpectedOutput.png, ActualOutput.png). Secondly, I would like to show bubbles with different colors (as "Vary By Colors" option in Excel). Please tell me how can we achieve these in the rad charts.

Thanks in advance,

Unable to reduce row height

I have attempted every way possible to reduce the row height of my grid, to no avail. I have tried changing the ItemStyle as such:

<ItemStyle Height="10px" Font-Size="X-Small"></ItemStyle>

I have attempted to change the values in the editor window. and finally, I customised the relative section of the style sheet. Does anyone have any ideas?

I can change every other aspect of the row, including increasing the row height; but the thing just won't shrink.

Find & Collapse Specific Group based on FieldName

Is it possible to collapse (or expand) a group based on the Group's FieldName property?

I have the following in my PreRender function, but it just collapses all groups:

foreach (var gi in rgVendorInvItems.MasterTableView.GetItems(GridItemType.GroupHeader))

{

gi.SetChildrenVisible(false);

}

Any input would be greatly appreciated!

How to get access to checkbox within RadMenu

Hi Telerik Support,

I have created a list of checkbox controls within Radmenu from code-behind with one root node and a list of menu-items directly under this root node with 3 columns - see attachment.

Test.aspx

<telerik:RadMenu runat="server" ID="RadMenu1" Skin="Vista"

DataFieldID="ItemId" DataFieldParentID="ParentItemId"

DataValueField="ItemId" DataTextField="Text" OnClientLoad="OnClientMenuLoaded">

<DefaultGroupSettings RepeatColumns="3" RepeatDirection="Vertical" />

</telerik:RadMenu>

Test.aspx.cs

namespace WebApplication1

{

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

{

protected override void OnInit(EventArgs e)

{

RadMenu1.ItemTemplate = new TextBoxTemplate();

base.OnInit(e);

}

protected void Page_Load(object sender, EventArgs e)

{

//Construct source list to bind to Menu

List<MenuSelection> lstV = new List<MenuSelection>();

MenuSelection lstItm;

for(int i = 1; i<= 50 ; i++)

{

if (lstV.Count == 0)

{

lstItm = new MenuSelection();

lstItm.ParentItemId = 0;

lstItm.ItemId = lstV.Count + 1;

lstItm.Checked = false;

lstItm.Text = "MenuLevel1";

}

else

{

lstItm = new MenuSelection();

lstItm.ItemId = lstV.Count + 1;

lstItm.ParentItemId = 1;

lstItm.Checked = GetSelectedList().Contains(lstItm.ItemId);

lstItm.Text = "MenuLevel2_" + (lstV.Count + 1).ToString();

}

lstV.Add(lstItm);

}

RadMenu1.DataSource = lstV;

RadMenu1.DataBind();

}

private List<int> GetSelectedList()

{

//Get the selected checkbox text from hidden field (where checkbox is checked)

List<int> selList = new List<int>();

foreach (string itm in hidSelectedList.Value.Split(new char[] { '|' }))

{

if (!string.IsNullOrEmpty(itm))

{

selList.Add(Convert.ToInt32(itm));

}

return selList;

}

public class MenuSelection

{

public MenuSelection()

{

}

public int ItemId { get; set; }

public int ParentItemId { get; set; }

public string Text { get; set; }

public bool Checked { get; set; }

}

class TextBoxTemplate : ITemplate

{

public void InstantiateIn(Control container)

{

CheckBox cb = new CheckBox();

cb.DataBinding += new EventHandler(cb_DataBinding);

container.Controls.Add(cb);

}

void cb_DataBinding(object sender, EventArgs e)

{

CheckBox target = (CheckBox)sender;

RadMenuItem item = (RadMenuItem)target.BindingContainer;

MenuSelection ds = (MenuSelection)item.DataItem;

target.Checked = ds.Checked;

target.Text = ds.Text;

target.ID = "ck";

target.Attributes.Add("onclick", "OnMenuCheck_Click('" + ds.ItemId.ToString() + "')");

}

My issue is:-
a) how can I use javascript to read all the text from checkbox (checked) and build a string store in hidden field so that I can access from code-behind.

b) When I check on the root node, all child-nodes will get checked. How to use javascript to read each checkbox in RadMenu?

c) I may add one hidden field together with checkbox in RadMenu then how to read this hidden field's value?

d) You have better way of presenting this design using other control?

I can use normal javascript to read them E.g. alert($get('RadMenu1_i0_i0_ck2').checked); But can I use the method provided by Telerik framework? I afraid this naming format may change in future by Telerik product upgrade. I have tried other methods provided in help file and from this forum with no help.

Anyone can help? Thanks in advanced.
