How to get grid reference from maste page?

Hi,

We have ASP.NET application that consists of master and content page. We load dynamically (using LoadControl method) our user control that has Telerik's grid. There can be 1 master and more detail grids. Detail grids are in separate rad tabs.

How can we get the reference to right grid from master page in case we selected particular tab where grid is placed?

The Ajax is enabled.

Thank you in advance.

how to update grid values with javascript then persist over postback

My grid has a mastertable and 1 detail table.
The master table has heirachyLoadMode="ServerBind"
The detailtable columns has ItemTemplates containing a RadNumericTextBox controls (1 per column).
The master table values are essentially an aggregation of the detail rows. I have RadNumericTextBox ClientEvents-OnValueChanged javascript that aggregates the detail values and updates the the value in the master row.

That all works. My problem is when a new row is expanded, a postback occurs and I loose the grid values I calculated and set via javascript. How do I persist those values? The values in the RadNumericTextBox controls are persisted so EnableViewState can be eliminated.

This is how I update the master rows:
masterView.getCellByColumnUniqueName(masterView.get_dataItems()[masterRowIndex], "MyColName").innerHTML = parseInt(detailTotal / detailRowCount);
How do I persist that change during postback? Am I not setting the value correctly? Do I have add postback code to copy HTML values to a saved datasource then rebind?

I cannot use heirachyLoadMode="Client" because loading takes way too long.
I am using ItemTemplates instead of EditTemplates because I don't want the user to have to click edit on each detail row they want to edit; that would slow them down a lot.

How to get data changes from transferred items

Hi everyone,
Any and all assistance here is greatly appreciated!

I'm trying to implement a Listbox Transfer scenario - allowing typical moving items from one list box to another.
The transferring of items back and forth is working fine.
The part that isn't working is getting changes to update a SQL database.
But once something is moved, the underlying dataTable doesn't have any changes.

What am I missing in order to acknowledge changes in the Selected dataTable?
Thank you in advance.

Here's the listboxes defined:

<telerik:RadListBox ID="RadListBox1" CssClass="RadListBoxAvailable" runat="server" SelectionMode="Multiple" AllowTransfer="True" TransferToID="RadListBox2" AllowTransferOnDoubleClick="True" EnableDragAndDrop="True" OnTransferred="RadListBox1_Transferred" AutoPostBackOnTransfer="True" Sort="Ascending"></telerik:RadListBox>

<telerik:RadListBox ID="RadListBox2" CssClass="RadListBoxSelected" runat="server" SelectionMode="Multiple" AllowTransferOnDoubleClick="True" EnableDragAndDrop="True" AutoPostBackOnTransfer="True" Sort="Ascending"></telerik:RadListBox>

And here's the c#:

using System;

using System.Configuration;

using System.Data;

using System.Data.SqlClient;

using Telerik.Web.UI;

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

{

public static DataTable dtSelected;

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

LoadAvailable();

LoadSelected();

}

private void LoadAvailable()

{

string query = "select personId, person from peopleList";

RadListBox1.DataSource = GetDataTable(query);

RadListBox1.DataSortField = "person";

RadListBox1.DataTextField = "person";

RadListBox1.DataValueField = "personId";

RadListBox1.DataBind();

}

private void LoadSelected()

{

string query = "select personId, person from peopleChosen";

dtSelected = GetDataTable(query);

RadListBox2.DataSource = dtSelected;

RadListBox2.DataTextField = "person";

RadListBox2.DataSortField = "person";

RadListBox2.DataValueField = "personId";

RadListBox2.DataBind();

}

private DataTable GetDataTable(string query)

{

String ConnString = ConfigurationManager.ConnectionStrings["wareConnectionString"].ConnectionString;

SqlConnection conn = new SqlConnection(ConnString);

SqlDataAdapter adapter = new SqlDataAdapter();

adapter.SelectCommand = new SqlCommand(query, conn);

DataTable myDataTable = new DataTable();

conn.Open();

try {adapter.Fill(myDataTable);}

finally {conn.Close();}

return myDataTable;

}

protected void RadListBox1_Transferred(object sender, Telerik.Web.UI.RadListBoxTransferredEventArgs e)

{

if (DataTableHasChanges(dtSelected))

{

LabelEditStatus.Text = "Changes not Saved";

}

else

{

LabelEditStatus.Text = "";

}

public bool DataTableHasChanges(DataTable dataTable)

{

return (dataTable != null) ? dataTable.GetChanges() != null : false;

}

[Solved] Am I using latest Radsplitter?

The following is mentioned in one of the web pages in the telerik site. We are using telerik in our application and the project started nearly 3 years ago. So, is there a way I can ensure I am using the latest RadSplitter which had this performance improvement?

RadSplitter

A brand new mechanism for updating RadSplitter's child controls was introduced that is many times faster than the old one which traversed every single HTML element to test whether it is a RadControl.

Custom callouts on RadHtmlChart

Is it possible to have a custom callout on a RadHtmlChart? (See attached - "Mailer Sent" and "Website Launched") The chart has three line series within it, using a date along the x-axis. I tried adding a scatter series to put an individual point on the chart, but when I specified a date for the XValue, it gave me an error (problem converting to integer)

Is this possible? Is it a matter of mixing two different types of charts? (lineseries and scatter) How can I best accomplish this?

Thanks!

Custom GridEditCommandColumn to Set one field

I love using the AutomaticDeletes, AutomaticEdit, and insert capability.

I have a list of tasks, and I want to add the ability to "complete" the task, without deleting it. I also want the leave the ability to edit the existing record, and delete the record. So, I need the "complete" column to update a single field for the selected record, then remove the line from the grid as the grid only shows uncompleted items.

Is there a way to do this?
Thanks for your help,
Dan

Radgrid resizing the wrong column

I have a dynamic grid that is able to change column widths and adjusts the grid's size to accommodate the grid size changes. However, when the user goes to drag a column, the column they are trying to select is not re-sized and instead another column (it changes from datasource to datasource) usually 1 or 2 columns to the right is re-sized instead. The only 2 columns that work as intended are the edit/delete columns which are hard coded into the grid. There is also a hidden column hard coded after the edit/delete columns as well that is required in certain places. Also, a few of the datasources use grouping. We are currently using version 2012.1.411 and do not have the option to update at this time. Below are the current radgrid settings we are using and I attached a screenshot to show the issue.
(in the screenshot I tried re-sizing "Total Acres" and instead it re-sized "Non Federal Acres" 2 columns over)

troubleshooting: I tried removing the hidden column and it did not affect the issue

current grid settings:
AutoGenerateColumns="true"

<GroupingSettings ShowUnGroupButton="true" CaseSensitive="false"

/>

<ClientSettings AllowDragToGroup="true" AllowColumnsReorder="true"

<Selecting AllowRowSelect="true" />

Resizing AllowColumnResize="true" EnableRealTimeResize="true" ResizeGridOnColumnResize="true" />

Scrolling SaveScrollPosition="false" AllowScroll="false"

/>

<ClientEvents OnPopUpShowing="PopUpShowing"

/>

</ClientSettings>
