Folks using VS 2010 with RadGrid for ASP.Net Ajax 2011 V2.

I have a Hierarchical grid, Master Table HierarchyLoadMode="Client".

If use use expand/collapse Expand/Collapse ImageUrl from a File via ColumnCreated event, I got the attached error message while exporting to PDF. But If i do not call Column created event in Radgrid thus by using default Expand/Collapse ImageURL, the PDF export works fine. Also if I use HierarchyLoadMode=Server or ServerOnDemand and call ColumnCreated event, export works fine.

Any help appreciated..

Thanks

Set focus on the radcombobox

Hi guys,
I have following code in my aspx page:

<

tr>

<td >

Please enter job posting number:

</p>

</td>

<td >

<telerik:RadNumericTextBox ID="JobPostingNo" runat="server" TabIndex="9" Font-Bold="true" MaxLength="4" Type="Number" MinValue="1" MaxValue="9999" CssClass="textbox" Width="48px" Enabled="false">

</telerik:RadNumericTextBox>

</td>

<td>

<asp:Image ID="JobPNErrImage" runat="server" Width="14px" Height="14px" ImageUrl="~/Image/error-icon.jpg" Visible="false" />

</td>

</tr>

<tr>

<td>

Have you met all of the criteria outlined in the posting?

</p>

</td>

<td>

<telerik:RadComboBox ID="ddlPost" runat="server" TabIndex="10" AutoPostBack="false" Font-Size="Small" Width="53px">

<Items>

<telerik:RadComboBoxItem Text="Select" Value="" Selected="true" />

<telerik:RadComboBoxItem Text="Yes" Value="Y" />

<telerik:RadComboBoxItem Text="No" Value="N" />

</Items>

</telerik:RadComboBox>

</td>

And here is a code behind file:

RadPanelBar

attestPanel = (RadPanelBar)formPanel.FindItemByValue("principalForm").FindControl("attestationPanel");

RadNumericTextBox jobPostNo = (RadNumericTextBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("JobPostingNo");

RadComboBox ddlAprvPost = (RadComboBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("ddlAprv");

if (ddlAprvPost.SelectedValue == "Y")

{

jobPostNo.Enabled =

true;

jobPostNo.Focus();

}

else

{

if (jobPostNo.Text.Length > 0)

{

jobPostNo.Text =

string.Empty;

}

jobPostNo.Enabled =

false;

}

My question is: when jobPostNo control is disabled how to shift focus to the next control right after this control.

Thanks so much.

How to get Detail Table row count from Client Side while Scrolling rows in Master Table.

Folks,

I am using ASP.Net Ajax Q2 2011 with VS 2010. Below is my Grid Table Laout.

Parent Table

---- Detail Table 1 (GridTableView Name = "Detail")

--- Detail Table 1.1

---- Detail Table 2

　
My desired expectations:

1) While I am scrolling rows in Parent Table, I would like to get the row counts of related Detail Table 1 but not row counts of other Detail Tables.

2) Also if I am scrolling rows in Detail Table 1, do nothing.

Below works to get the Row Count of Parent Table; but having some difficulty to getting row count of Related Detail Table 1.

function RowCount(sender, args)

{

var grid = $find("<%=RadGrid1.ClientID %>");

var MasterTable = grid.get_masterTableView();

var Rows = MasterTable.get_dataItems();

  // Need Help here to get the Row Count of Detail Table 1 and Pass into TextBox RowCountTextBox...



    alert(Rows.length);

document.getElementById("<%=RowCountTextBox.ClientID %>").value = parseInt(Rows.length);

}

Rad Grid Settings: 

'''

 

HierarchyLoadMode = "ServerBind"

 
'''

<ClientEvents OnFilterMenuShowing="filterMenuShowing" OnRowSelected = "RowCount" />

'''

<asp:TextBox ID="RowCountTextBox" runat="server" Text="" Width = "400px"> </asp:TextBox>

I tried in Server Side Prerender event, but did not get the Child Table row count if Parent row is not expanded.

Thanks

[Solved] RadGrid Problem

Hello,

i'm having a problem with my RadGrid, At this moment i need to bind data to my Grid using 2 diferent Store Procedures, mapped on my .edmx.

The idea is to have two buttons, each one to call a procedure. At this moment My problem is when I click on a collumn to sort data, my grid comes blank....I need to allow my RadGrid to sort collumns but for the specific procedure that was bind at last.

How can i do that?

My code is

public partial class InvoicesScalingDefault : iConnect.Web.iConnect, IInvoicesScale

{

private InvoicesScalePresenter _presenter;

public System.Collections.Generic.IList<Data.SapDocuments> SapDocuments

{

get;

set;

}

protected void Page_Load(object sender, EventArgs e)

{

if (!this.IsPostBack)

{

this._presenter.OnViewInitialized();

LoadData();

}

this._presenter.OnViewLoaded();

}

[CreateNew]

public InvoicesScalePresenter Presenter

{

set

{

this._presenter = value;

this._presenter.View = this;

}

/// <summary>

/// Carregar RadGrid1 com o objecto SapDocuments

/// </summary>

private void LoadData()

{

string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);

EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();

RadGrid1.DataSource = objectContx.ShowUnprocessedInvoices(user);

//RadGrid1.DataBind();

}

protected void RadGrid1_GridExporting(object sender, GridExportingArgs e)

{

e.ExportOutput = e.ExportOutput.Replace("\"\r\n\"", "\"\r\n\"'");

}

protected void ShowProcessed_Click(object sender, EventArgs e)

{

string user = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf("\\") + 1);

EscalonamentoFacturasEntities objectContx = new EscalonamentoFacturasEntities();

RadGrid1.DataSource = objectContx.ShowProcessedInvoices(user);

RadGrid1.DataBind();

}

protected void ShowUnProcessed_Click(object sender, EventArgs e)

{

Formatting input and display with RadDateInput

I'm trying to add a control to a web page that allows the user to enter date values in a variety of ways, hoping the control will display in the correct format. I currently use a date type in another product that automatically formats the input to the correct value. Example: if the user types in 05052005, the control should convert the value to 5/5/2005, conversely if the user enters 05/05/2005, the control should convert to 5/5/2005.

Any ideas or help is welcomed.
