GridTableView events?

Hi, I have a RadGrid with a nested GridTableView. I am trying to hook up the OnPreRender event, but it doesn't ever seem to get called. After further experimentation, none of the events seem to be called on this object. The grid exhibits the same behaviour when removed from the AjaxManager. Do I need to do something else to hook up these events?

Thanks

Change group value coming from database

Hi, I want to know if when using grouping if it is possible to change the group for an item. I have an item that has Group A in the database, but in the vb code-behind I need to change the item to Group B so it gets reported under Group B. I have tried changing the GridItem("MyGroup").Text in the ItemDataBound event, but the item doesn't appear under the correct group (even though the text has been changed.

Thanks.

RadNumericTextBox - maxlength for decimal and non-decimal digits

Hi,
I'm using RadNumericTextBox. In a database I have a column e.g.: Preis decimal(12,2) - oracle.
How can I set in RadNumeric maxlength of digits to 12 for non-decimal digits and 2 for decimal digits?
And another question: when I set maxvalue, when user inputs more digits, the value is automatically sets to maxvalue without any question or warning. Why?

loop through diamically created checkbox column problem - can't find checkbox control on the page

We have a diamically created radgrid with lots checkbox column in it. They all display fine. But I have problem for looping through it and get it's value. It seems can't find the checkbox control on the page. Not sure where I missed.

foreach (Functions function in CurrentUserFunctionList)

{

// Set up the RadGrid's columns

// NOTE: We have to use a custom TemplateColumn, because each checkbox is its own unique control, with its own unique ID.

GridTemplateColumn gtcFunction = new GridTemplateColumn();

gtcFunction.HeaderText = function.Description;

gtcFunction.DataField = function.FunctionId.ToString();

gtcFunction.ReadOnly = false;

gtcFunction.AllowFiltering = false;

// NOTE: The FunctionId gets passed in because it's part of each checkbox control's ID...

gtcFunction.ItemTemplate = new RadGridCheckBoxTemplate(function.FunctionId.ToString());

rgWeb.MasterTableView.Columns.Add(gtcFunction);

// Set up the Data Table's columns

DataColumn thiscolumn = new DataColumn();

thiscolumn.Caption = function.Description;

thiscolumn.ColumnName = function.FunctionId.ToString();

thiscolumn.ReadOnly = false;

thiscolumn.DataType = System.Type.GetType("System.Boolean");

MyDataTable.Columns.Add(thiscolumn);

}

public class RadGridCheckBoxTemplate : System.Web.UI.ITemplate

{

private string colname;

/// <summary>

/// This class sets up a Template with dynamically named CheckBoxes in the RadGrid. cName is the unique identifier for th column,

/// which is added to the ID of each CheckBox control.

/// </summary>

/// <param name="type"></param>

public RadGridCheckBoxTemplate(string cName)

{

this.colname = cName;

}

/// <summary>

/// Create the template

/// </summary>

/// <param name="container"></param>

public void InstantiateIn(System.Web.UI.Control container)

{

CheckBox checkbox = new CheckBox();

//checkbox.AutoPostBack = true;

checkbox.DataBinding += new EventHandler(boolValue_DataBinding);

checkbox.ID = "cbox_" + colname;

checkbox.CheckedChanged += new EventHandler(ToggleRowSelection);

container.Controls.Add(checkbox);

}

void boolValue_DataBinding(object sender, EventArgs e)

{

CheckBox cBox = (CheckBox)sender;

GridDataItem container = (GridDataItem)cBox.NamingContainer;

cBox.Checked = (bool)((DataRowView)container.DataItem)[colname];

}

/// <summary>

/// Check and uncheck

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

void ToggleRowSelection(object sender, EventArgs e)

{

((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked;

}

I need to loop throug the radgrid to get all the column,

use CheckBox cb = (CheckBox)gdi.FindControl(controlname);
or :

foreach (Control ctrl in Page.Controls)

{

if (ctrl is CheckBox)

{

string a = ctrl.ID;// never comes here to show the control id

}

I can't find any chekbox control on my page, not sure why?

Working with RadGrid and TemplateColumns in ItemCommand

Telerik,

Im trying to get the value of a TemplateColumn item when the ItemCommand event is raised. My TemplateColumn looks like the following:

<telerik:GridTemplateColumn HeaderText="User" UniqueName="User" Reorderable="false" Display="true" SortExpression="User">

<ItemTemplate>

<asp:LinkButton ID="btnButton1" runat="server" ToolTip="Edit this user" CommandName="EditUser" Visible="<%# Master.UserPrefs.HasEditRights %>"><%# Eval("User") %></asp:LinkButton>

<asp:Label ID="lblLabel1" runat="server" Visible="<%#!Master.UserPrefs.HasEditRights %>"><%# Eval("User") %></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

Basically, the template is built using a boolean value (determining if the current user logged in has EditRights to the record) to either display a LinkButton (to launch a custom edit screen) or to display a Label (if the current user doesn't have the appropriate permission).

In the ItemCommand, I would like to get the value of the data bound to either the Label or the LinkButton. The closest I got to getting the information is by doing something like the following:

protected void gvUsers_ItemCommand(object sender, GridCommandEventArgs e)

{

RadGrid grid = (RadGrid)sender;

switch (e.CommandName.ToUpper())

{

case "MyCommandName":

foreach (GridDataItem item in grid.MasterTableView.Items)

{

string cellContent = ((GridLinkButton)item.Cells[3].Controls[0]).Text

}

		      break;

        }

}

Is this the only way to get the Text value of the GridLinkButton? Can you please provide any other information for retrieving the values associated with a TemplateColumn using the markup in my Template?

Thanks
