[Solved] How do I loop through rows in a EditItemTemplate server side?

I have a grid that has a GridTemplateColumn, with an EditItemTemplate inside. Inside the EditItemTemplate is a RadNumericTextBox. I'm trying to loop through the rows in the grid server side, outside the normal RadGrid events. I have a button that when clicked sends me server side and in that event I need to loop through and grab the values from all the rows.

I have no problem grabbing the DataKeyValue for the row, it's just the value of txtQuantity I am unable to get.

Here is my ASCX:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" DataSourceID="Products"

Skin="Forest" GridLines="None" OnItemDataBound="RadGrid1_ItemDataBound" Width="50%">

<ClientSettings>

<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="true" ></Scrolling>

</ClientSettings>

<MasterTableView ShowFooter="true" AutoGenerateColumns="False"

CurrentResetPageIndexAction="SetPageIndexToFirst" DataKeyNames="ID" DataSourceID="Products"

Dir="LTR" Frame="Border" TableLayout="Auto" EditMode="Batch" BatchEditingSettings-OpenEditingEvent="Click" CommandItemDisplay="None">

<Columns>

<telerik:GridBoundColumn DataField="ID" DataType="System.Int32" ReadOnly="True" UniqueName="ID" />

<telerik:GridBoundColumn DataField="ProductName" ReadOnly="true" HeaderText="Product" UniqueName="ProductName" />

<telerik:GridTemplateColumn DataField="Quantity" UniqueName="Quantity" HeaderText="Quantity" DataType="System.Int32">

<ItemTemplate>

<%# Eval("Quantity")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadNumericTextBox ID="txtQuantity" runat="server" Width="40px" DataType="System.Int32"

NumberFormat-DecimalDigits="0" Skin="Forest">

<ClientEvents OnBlur="Blur" OnFocus="Focus" />

</telerik:RadNumericTextBox>

</EditItemTemplate>

<FooterTemplate>

<telerik:RadNumericTextBox ID="TextBox2" runat="server" Width="40px" DataType="System.Int32" NumberFormat-DecimalDigits="0" Skin="Forest" ReadOnly="True">

<ClientEvents OnLoad="Load" />

</telerik:RadNumericTextBox>

</FooterTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

</telerik:RadGrid>

Here is my Server side:

Protected Sub btnProcess_Click(sender As Object, e As EventArgs)

Try

For Each row As GridDataItem In RadGrid1.MasterTableView.Items

Dim key As String = row.GetDataKeyValue("ID")

Dim qty As RadNumericTextBox = DirectCast(row("Quantity").FindControl("txtQuantity"), RadNumericTextBox)

Next

Catch ex As Exception

Response.Write(ex.ToString)

End Try

End Sub

Problem with online demo in Safari (iPad)

At my development machine, I can run the Olympic Games Medals by Sport online demo with no problem. I can click on any bar in the "Medals by Sport" bar chart, and it shows the label (example: 33 medals) and the "Medal Type" pie chart updates accordingly.

However, attempting to demonstrate that to my supervisor on his brand-new iPad Mini using the Safari browser, I can click on any bar and it shows the label - but the "Medal Type" pie chart does not ever update. It only ever displays the Gold/Silver/Bronze medal breakdown for the first bar.

Does anyone know what it would take to fix this demo? I was trying to show that the Telerik controls would work in any browser.

Captcha audio generated as iamge

Hi,

1. We have a form with Captcha.

2. If user try to get the audio, browser will try to get the link below:
~/Telerik.Web.UI.WebResource.axd?type=cah&guid=84332214-d590-4e5d-8070-c903a4cf548e

3. As you can see in generated HTML, instead of audio, it generate an embed.

<div id="dp_swf_engine" style="position: absolute; width: 1px; height: 1px;"><embed style="width: 1px; height: 1px;" type="application/x-shockwave-flash" src="http://www.ajaxcdn.org/swf.swf" width="1" height="1" id="_dp_swf_engine" name="_dp_swf_engine" bgcolor="#336699" quality="high" allowscriptaccess="always"></div>

4. It happens only in this hosting package.

5. Is it caused by the server's permission issue or other reasons?

Thanks.

PDF Export

Hi,

I am trying to export PDF from my RadGrid and its exporting successfully. But i am facing some design issues in the exported PDF file.

1. All the text are coming with Hyperlinks in the exported PDF.
2. Set the Forecolor and width, which are not getting reflected in the exported PDF.

Below is my c# code

protected void btnExportToPDF_Click(object sender, ImageClickEventArgs e)

{

ApplyStylesToPDFExport(RadGrid1.MasterTableView);

RadGrid1.ExportSettings.OpenInNewWindow = true;

RadGrid1.ExportSettings.IgnorePaging = true;

RadGrid1.ExportSettings.FileName = "Test";

RadGrid1.MasterTableView.ExportToPdf();

}

private void ApplyStylesToPDFExport(GridTableView view)

{

GridItem headerItem = view.GetItems(GridItemType.Header)[0];

foreach (TableCell cell in headerItem.Cells)

{

switch (cell.Text)

{

case "A":

cell.Width = Unit.Pixel(5); // Tried like this. Not reflecting

break;

case "B":

cell.Style["width"] = "15px"; // Tried like this. Not reflecting

break;

}

cell.Style["font-family"] = "Verdana";

cell.Style["font-bold"] = "true";

cell.Style["text-align"] = "left";

cell.Style["vertical-align"] = "middle";

cell.Style["font-size"] = "8px";

cell.ForeColor = System.Drawing.Color.Black; // Tried like this. Not reflecting

}

GridItem[] dataItems = view.GetItems(GridItemType.Item);

foreach (GridItem item in dataItems)

{

foreach (TableCell cell in item.Cells)

{

cell.Style["font-family"] = "Verdana";

cell.Style["text-align"] = "left";

cell.Style["vertical-align"] = "left";

cell.Style["font-size"] = "6px";

cell.Style["text-decoration"] = "none"; // Tried like this. Not reflecting

cell.Style["ForeColor"] = "#000";

}

dataItems = view.GetItems(GridItemType.AlternatingItem);

foreach (GridItem item in dataItems)

{

foreach (TableCell cell in item.Cells)

{

cell.Style["font-family"] = "Verdana";

cell.Style["text-align"] = "left";

cell.Style["vertical-align"] = "middle";

cell.Style["font-size"] = "6px";

cell.Style["text-decoration"] = "none";

cell.ForeColor = System.Drawing.Color.Black;

}

Please advise.

Thanks

[Solved] Is this expected behavior of RadAjaxManager

Hello, I hope community and Telerik staff will help me to understand if I want too much from RadAjaxManager, and point me what I'm doing wrong.
Trying to explain to support person my problem for almost 4 days now, and still did not get any clear answer, or confirmation that behavior I'm expecting is bug or "by-design".

Anyway, I'm having RadScriptManager and RadAjaxManager controls created on my master page, and then I have this on my content page:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<telerik:RadAjaxManagerProxy runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="cmdButton1" EventName="Click">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnl1" />

<telerik:AjaxUpdatedControl ControlID="pnl2" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="cmdButton2" EventName="Click">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnl2" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<asp:Button ID="cmdButton1" runat="server" Text="Button 1" OnClick="cmdButton1_Click" />

<asp:Panel ID="pnl1" runat="server">

<asp:Button ID="cmdButton2" runat="server" Text="Button 1" OnClick="cmdButton2_Click" />

<asp:Label ID="lblPnl1" runat="server" />

</asp:Panel>

<asp:Panel ID="pnl2" runat="server">

<asp:Label ID="lblPnl2" runat="server" />

</asp:Panel>

</asp:Content>

and this is code I have in code-behind

protected void Page_Load(object sender, EventArgs e)

{

lblPnl1.Text = lblPnl2.Text = DateTime.Now.ToString();

}

protected void cmdButton1_Click(object sender, EventArgs e)

{

//do nothing Page_Load will update content of labels

}

protected void cmdButton2_Click(object sender, EventArgs e)

{

//do nothing Page_Load will update content of labels

}

As you can see I have 2 buttons, and I defined for them 2 AjaxSettings inside RadAjaxManagerProxy
So, according to these settings I'm expecting the following behavior:

1. When button cmdButton1 is clicked - RadAjaxManager should refresh my pnl1 and pnl2 Panels
2. When button cmdButton2 is clicked - RadAjaxManager should only refresh my pnl2 Panel.

However, when I'm clicking cmdButton2 - BOTH panels beeing refreshed.

If I remove AjaxSetting for button1 and click button2 - things starting work as expected (e.g. pnl1 is not refreshing)

So it seems that AjaxSetting for button1 somehow forces RadAjaxManager to refresh pnl1, even when button1 was not clicked.

Is this expected? Or bug? What you guys think? What behavior you would expect?

I gave up trying to explain why I think this is bug to support person :(

Maybe I don't understand something?

Thanks!
