Radgrid Row Controls collection client side

Hello,

I need to be able to add dynamically created textboxes to my Grid rows. I'm doing that in the grid's ItemCreated event. However, on post back my text boxes are being recreated and therefore losing their values. I don't want to have to recreat my textbox controls in Page_Init. I had an idea to read the textbox values on the client side and write them to a hidden field control. The problems is that I can't figure out how to access the SelectedRow's controls collection to find my text boxes.
Also, the number of text boxes per row is also dynamic. Meaning Row 1 may have just 1 textbox while Row 2 has 3. This is why i need to be able to dynamically loop the row's controls since I won't know exactly how many text boxes were created for a given row
Here is what I'm trying to do

function RowSelected(row)

{

for (i=0;i<row.Controls.count;i++)

{

if (row.Controls[i].type == "text")//if the type of control is textbox

{

alert(row.Controls[i].id);

}

}

I'm getting a javascript error that controls.count is null

How can I accomplish this task? It's doesn't have to be the same solution as outlined above. I just need to be able to create those text boxes at run time and access their values on the server at postback.

Thanks in advance ;)

[Solved] Change the text that appears for NextPages / PrevPages

Hi,

I'm wondering if there is a way to specify what text I want for the "NextPages" / "PreviousPages" in the RadGrid PAger Control. I see there is a property for NextPagesToolTip but there is not one for NextPagesText. I would like to display "Next Pages" instead of "...".

1 2 3 4 5 6 7 8 9 10 ... I want to be 1 2 3 4 5 6 7 8 9 10 Next Pages

Thanks

<PagerStyle Mode="NumericPages" Position="TopAndBottom" CssClass="ListingsPageing" PrevPageImageUrl="/images/prev.jpg" NextPageImageUrl="/images/next.jpg"></PagerStyle>

RAD WindowManager Customized Buttons

Hi

I am using the RAD Window Manager to display the alert messages and confirm messages.
The Current version uses Template regions to display alert, confirm and prompt messages.

I need to add customized Buttons instead of the normal yes and no Button.
I have tried to create my own style sheet for the Customized Buttons  but looks like the CSS is not working when i try to create an user control for the Confirm Template.and apply the CSS to the Button.
Below is the code snippet which i am using to create an ConfirmTemplate userControl

<link href="../../../App_Themes/CSS/Sample.css" rel="Stylesheet" type="text/css" />

<div class="rwDialogPopup radconfirm">
<div class="rwDialogText">
{1}
</div>
<div>
<a onclick="$find('{0}').close(true);"   href="javascript:void(0);" ><div class="button1"></div></a>
<a onclick="$find('{0}').close(false);"  href="javascript:void(0);"><div class="button2"></div></a>
</div>
</div>

Can you please suggest me some ways to achieve it.

Regards

Export Error!!!

I have a RadGrid which has export buttons above it that I use to export to excel, word, and pdf. They work fine on all of my other pages. However, we are experiencing a major issue when I have some code behind writing to a tooltip.

ToolTip components from RadControls

    
            <telerik:GridTemplateColumn HeaderText="Actions" HeaderStyle-Width="50" ItemStyle-HorizontalAlign="center">     
        
               <ItemTemplate>    
        
                 <telerik:RadToolTip ID="RadToolTipMessage" TargetControlID="LabelRefreshStatus" RelativeTo="Element" Position="BottomLeft" runat="server" />   
        
                 <telerik:RadToolTip ID="RadToolTipImage" TargetControlID="ImageErrorMessage" RelativeTo="Element" Position="BottomLeft" ManualClose="true" runat="server" />   
        
                 <asp:ImageButton ID="ImageButtonDetails" ImageUrl="~/images/office/txt.gif" AlternateText="See Details" runat="server" />    
        
                 <asp:Label ID="LabelRefreshStatus" runat="server" />   
        
                 <telerik:RadToolTip ID="RadToolTipDetails" TargetControlID="ImageButtonDetails" Position="TopLeft" Sticky="true" runat="server" />   
        
               </ItemTemplate>    
        
            </telerik:GridTemplateColumn>

Code Behind for ToolTip

    
            refreshStatus.Text = EMAUtilities.BatchStatus(Convert.ToInt32(dataItem["STATUS_ID"].Text));     
        
            RadToolTip message = ((RadToolTip)e.Item.Cells[0].FindControl("RadToolTipMessage"));     
        
            RadToolTip imageMessage = ((RadToolTip)e.Item.Cells[0].FindControl("RadToolTipImage"));     
        
            RadToolTip detail = ((RadToolTip)e.Item.Cells[0].FindControl("RadToolTipDetails"));

RAD GRID Paging not working properly

I'm using rad grid and databind using following code.

grdMyGrid.DataSource = myDataTable

grdMyGrid.DataBind()

For the first time it works fine.
[Record count: 18]
[Paging Size: 10]
[Pager Display as : 1 2 ]

Then I change the default contents of the 'myDataTable' data table and add more records to the  'myDataTable' data table.
Then I re-call above code to bind that new data table.

Thats also working fine. When there are record count more than pager size, It adds those page numbers to the pager(Page moving segment of grid).
[Record count: 38]
[Paging Size: 10]
[Pager Display as : 1 2 3 4 ]

Again I'm changing the contents of the 'myDataTable' data table and remove many records to the  'myDataTable' data table
Then I re-call above code to bind that new data table.

In this case, it do not hide the additional page numbers.
[Record count: 08]
[Paging Size: 10]

[Pager SHOULD Display as : 1 ]
BUT Display it display As :
[Pager Display as : 1 2 3 4 ]

What would be the issue?
Ur support is highly appreciated.

Horizontal flow for ContextMenu

I'm trying to get a ContextMenu to display the root items horizontally. Here's the code:

    
            <telerik:RadContextMenu ID="pageSelectMenu" runat="server" ClickToOpen="false" Flow="Horizontal" > 
        
                <Items> 
        
                     <telerik:RadMenuItem Text="page1" ></telerik:RadMenuItem> 
        
                     <telerik:RadMenuItem Text="page1b"></telerik:RadMenuItem> 
        
                </Items> 
        
            </telerik:RadContextMenu>

When this gets displayed, the menu items are vertical. When I look at the rendered output, the ul for the menu has

class="rmActive rmVertical rmGroup rmLevel1"

What am I missing? The control version is 2008.3.1314.35
