RadContextMenu doesn't appear on grid row

Hi,

I have 2 projects:

1) Simple test project - I create RadContextMenu that is associated with grid's row and it appears normally. I create it programmatically in Page_Init event. I don't use ContextMenuControlTarget. Telerik's grid and RadContextMenu are inside user control. The code looks as following:

public partial class GridUserControlDynamic : System.Web.UI.UserControl

{

public RadContextMenu contextMenu = new RadContextMenu();

protected void Page_Init(object sender, EventArgs e)

{

contextMenu.ID = this.GridControl.ID + "_RadMenu";

RadMenuItem item1 = new RadMenuItem("Add");

RadMenuItem item2 = new RadMenuItem("Edit");

RadMenuItem item3 = new RadMenuItem("Delete");

RadMenuItem item4 = new RadMenuItem("Parus");

contextMenu.Items.Add(item1);

contextMenu.Items.Add(item2);

contextMenu.Items.Add(item3);

contextMenu.Items.Add(item4);

contextMenu.ItemClick += contextMenu_ItemClick;

Controls.Add(contextMenu);

2) Complex project - I create RadContextMenu that should be associated with grid's row but it doesn't appear at all. I create it without ContextMenuControlTarget programmatically in OnInit method. But when I use ContextMenuControlTarget it appears but it's available not only on grid's row but in grid's header too. I don't need it in grid's header. The code looks as following:

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

...

// Grid context menu section

var contextMenu = new Parus.Controls.GridContextMenu();

var target = new ContextMenuControlTarget();

target.ControlID = this.Grid.ID;

contextMenu.ID = this.Grid.ID + "_RadMenu";

CreateContextItems(contextMenu.Items, this.Frame.ViewFrameData.ActionItems);

contextMenu.LinkedControlClientId = ServerRequest.ClientID;

contextMenu.OnClientItemClicked = "GridContextMenu_ActionsHandler";

contextMenu.Targets.Add(target);

this.PostbackPanel.ContentTemplateContainer.Controls.Add(contextMenu);

The CreateContextItems method add items to context menu.

How to get rid of context menu appearance in grid's header?

Retaining Filter values in the radcombobox

Hi all,

This is my first posting here and I could use your help. I am trying to figure out how to keep my values when using a radcombo box when filtering my grid. Each time I select an option, the selected value always go back to the first in the list. So I added some code in the cs file to retain the value, but I get an error. I could use your expertise! I have cut/pasted the code and the error message below.

Here is the Aspx:

Here is the code-behind:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using CPSTrainingLog.DAL;

using Telerik.Web.UI;

using System.Drawing;

namespace CPSTrainingLog

{

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

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

if (item["Status"].Text == "1")

{

item["Status"].Text = "Active";

item["Status"].ForeColor = Color.Green;

}

else if (item["Status"].Text == "0")

{

item["Status"].Text = "Inactive";

item["Status"].ForeColor = Color.Red;

}

protected void StatusCombo_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

GridFilteringItem item = RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem)[0] as GridFilteringItem;

RadComboBox radComboBoxFilterStatus = item["Status"].Controls[0] as RadComboBox;

string filterStatus = Convert.ToString(radComboBoxFilterStatus.SelectedValue);

RadGrid1.MasterTableView.FilterExpression = string.Empty;

if (e.Value.Equals("1") || e.Value.Equals("0"))

{

RadGrid1.MasterTableView.FilterExpression = RadGrid1.MasterTableView.FilterExpression + string.Format("it.[Status] = {0}", Convert.ToInt32(e.Value));

}

GridColumn columnID = RadGrid1.MasterTableView.GetColumnSafe("Status");

columnID.CurrentFilterValue = filterStatus;

RadGrid1.Rebind();

}

and here is the error i get after filtering on the Status column:

Calendar input truncated when using DateInput

Hi,

I have a RadDateTimepicker and changed the font size to 20px and when I assign a date/time to it using SelectedDate, the text is truncated. See attached picture and notice the PM is missing. I have pasted my code.

Datey.SelectedDate = now

Browser: IE 10

When I change the font to 15px, all shows fine.

Thanks.
Tim

<telerik:RadDateTimePicker ID="Datey" Style="vertical-align: middle;" Width="300px" runat="server" Skin="Default" Culture="English (United States)" EnableTyping="False">

Create bar and Pie Charts

I am in the process of taking all my Sql reports in sql reporting and moving to Telerik reporting. Went to it becuase it was easy but its hard to maintain another server. So what I would like is help in developing my first chart. what I need to do is pull my information from a database and then rotate through it to add my data. My first chart is pretty simple I need to create the side lengend based on amount of personnel it pulls from the database and then create a legend based on if they had have certain reviews done on them.
Annual
Ready
Not COmpleted

These should be in bar chart to show this. My question is how to do this. Are these seperate series or one series, i don't get the linog on the asp.net side.

How can i rotate through my datatable to get all this.

<telerik:RadChart ID="RadChart1" runat="server" Width="500px" >

<Legend>

<Items>

</Items>

</Legend>

</telerik:RadChart>

Select Total, Readiness, Annual, NoComplete from #TempCount

So total would be the bar charts left legend for total # of personnel subdivided into 20 personl incriments,
then you would have 3 bars Readines, Annual and noComplete.

Problem with x-axis label placement

Hello forums,

We are having a weird issue with RadChart in that sometimes the chart goes wonky when it is placing the labels for the dots on a line chart. Yes, the dots are a bit close together, but it doesn't seem like they are all that terribly close together. It's possible that this is just a RadChart bug. We are currently using RadChart (ASP.net AJAX) version 2012.2.828.40. Attached are some sample graphs for you to peruse. Any suggestions of things we could try to tweak to keep this from happening would be welcome.

Thanks in advance,

Scott

Overlap the image in StackedBar type of chart to all the series items based on specific value

Hi Friends,

We have requirement to display the image in the particular position of the every series item of StackedBarchart. When we tried this, the whole value of series item is changed as image.

  foreach (ChartSeriesItem seriesItem in seriesGroup.Items)
        {
              seriesItem.Appearance.FillStyle.FillSettings.BackgroundImage = "~/starimage.jpg";
               seriesItem.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Image;

}

For your reference, required chart image file is attached.

Please help us to achieve this functionality.
