Questions on UI for ASP.NET AJAX Forum

I am working on a radgrid set to AllowMultiRowEdit="false".
When I click on Edit for a data row, data row goes into Edit mode.
If I clicked on another data row, that data row then goes into Edit mode, and the previous data row is no longer in Edit mode (as should happen).
If I click on 'Add New Row', any data row previously in Edit mode is no longer in Edit mode (as should happen, and that is what I want to see as well).

NOW: with an Insert row on display, if I click 'Edit' on a data row, I now have an Insert row AND a data row in Edit mode.
What I would prefer is for the Insert row to disappear.

Is there a way to do this?

I believe there is a way to do this with NewEditIndex property of ASP.NET grid (or list), but I scoured the radgrid and could not find a property via which to achieve this.

Thank you in advance for input.

telerik:GridBoundColumn

I have entries from a SQL database that I am trying to display in a telerik:GridBoundColumn. The entries are multi-lined, with "\r\n" indicating the end of the line.
When the data displays in my "EditForm" it looks fine, but the RadGrid column itself it does not display the "new lines", it just displays my data in one long string.
Can someone tell me how to make RadGrid columns recognize newline characters?

Thanks
(sorry if this is the wrong place to ask this question, I am very new to telerik)

Code snipit -

<telerik:GridBoundColumn HeaderText="Recovery Steps" DataField="RecoverySteps" UniqueName="RecoverySteps">

</telerik:GridBoundColumn>

RadListView custom drag handle definition

Scenario1: I'm trying to set the custom drag handle for the list view items.    I used the below code snippet to my Listview control Image item. The below "onmousedown" event works fine for the first time of page load of Radlistview.

   <ItemTemplate>
       <div class="rlvI">
           <div class="rlvDrag"
            onmousedown="Telerik.Web.UI.RadListView.HandleDrag(event, '<%# Container.OwnerListView.ClientID %>', <%# Container.DisplayIndex%>)">
           </div>
       <div>
   </ItemTemplate>

Isssue: Within application I'm changing the listview data and populating through AJAX method.   After the data gets rebinded in the RadListview the event is not working and not able to drag the items.   Do I need to dynamically set this event for new Listview items at runtime ?    How do I set this "onmousedown" event dynamically in the codebehind while populating the listview ?

Scenario2: Similar issue happens if I use the RadListViewItemDragHandle, it is throwing item_drag is null during the mousedown of the draghandle item for the second time after listview rebind. I'm thinking the item is not set correctly for dynamically changing listview items in both the scenarios.

Any help is much appreciated..

Thanks

Added Custom Header Row - How Do I Remove or Suppress the "rgHeader" Css Class from the Generated <TH> Element?

Telerik.Web.UI v2010.3.1109.35

We have a radgrid (Theme/Skin="Windows7") and we've added a custom header row like this:

// ***** Add Grid Header Summary Row *****

GridItem[] header = this.MyWorkRadGrid.MasterTableView.GetItems(GridItemType.Header);

//get the current THead element

GridTHead head = ((GridTHead)header[0].Parent.Controls[1].Parent);

//create a new GridHeaderItem which will be the new row

GridHeaderItem newHeaderItem = new GridHeaderItem(this.MyWorkRadGrid.MasterTableView, 0, 0);

newHeaderItem.Width = Unit.Percentage(100);

newHeaderItem.Height = Unit.Pixel(23);

// Create a cell to hold the toolbar

GridTableHeaderCell newHeaderCell = new

GridTableHeaderCell() { Width = Unit.Percentage(100), HorizontalAlign = HorizontalAlign.Left, VerticalAlign = VerticalAlign.Top };

newHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = "" });

newHeaderCell.ColumnSpan = 5;

newHeaderItem.Width = Unit.Percentage(100);

newHeaderItem.Height = Unit.Pixel(23);

// Create the toolbar

RadToolBar toolBar = new RadToolBar();

toolBar.Height = Unit.Pixel(23);

toolBar.Skin = "Windows7";

toolBar.Width = Unit.Percentage(100);

// Create the toolbar item

RadToolBarButton button = new RadToolBarButton("Contact List");

toolBar.Items.Add(button);

// Add Controls

newHeaderCell.Controls.Add(toolBar);

newHeaderItem.Cells.Add(newHeaderCell);

for (int i = 0; i < head.Controls.Count; i++)

{

// loop through the header controls collection and find the 'row' that has the same type of GridHeaderItem

// Then insert the new row just above it - remember the 0 based index will push the original header row down

if (head.Controls[i].GetType() == newHeaderItem.GetType())

{

head.Controls.AddAt(i, newHeaderItem);

}

In this case, we added a toolbar to the header to be consistent with toolbars we have as headers on a left and right pane that sit next to this grid in the center pane.
The output of this is shown in image "Ex1.jpg" where the text is "Contact List".

The problem is that the new grid header has default padding that ends up surrounding any content you put into it.
See image "Ex2.jpg" where the purple color is the padding surrounding our content (which is a RadToolBar shown in blue shade).

When you look at the output in FireBug, the offending css class is "rgHeader" on the generated <TH> element.
See image "Ex3.jpg" - highlighted in blue.

When I use FireBug to remove that class, the padding is gone and the toolbar takes up the entire space (no more padding) and matches the other toolbars across all RadPanes.
See image "Ex4.jpg" - you can see "Contact List" toolbar text matches the toolbar on the left pane "My Workspace".

We want to keep the Windows7 Themes on the controls but can you show me how to remove or suppress that "rgHeader" class from the generated <TH> element so that we do not have to deal with the left,top,right,bottom padding it generates?

If solution can be done in code-behind, great, give me that.
If solution is style/css based in aspx page, then show me what I need to do/add.

Thanks,
Ray

RadGrid ItemStyle Padding-Right

Hi
A bit of a newbie question so should be quick to answer. I have created a radgrid with some columns with numeric data that also have filters. I have aligned these columns right but that leaves my text aligned with the filter symbol. I would like to add right padding to the cells so that the text is indented. I have applied a CssClass which works for font, background etc but I din't have any success when using the padding-right statement. Here is my code:

ASPX

CSS

.ItemCellPad

{

padding-right:10px;

}

What am I doing wrong??

cheers

Get file size client side

Hi,
I have been trolling through the forums and documentation for the AsyncUpload control and I was trying to find out if there is a method or property available client-side that would let me get the size of the file uploaded. It could be either before or after the file is uploaded, although I would prefer before. I was trying to use the following -

sender._uploadedFiles[0].fileInfo.ContentLength

But that only works on smaller files. If I upload a 5mb file the content length is only around 500,000 or so, and on a 3mb file it is 1,800,000. I would have thought something like InputStream.Length would be available client side???

Thanks

Matt.

Self Referencing Grid - Unable to edit child row

Hi, sorry if this is a basic question but I need some direction on how to call editItem() client-side on a child row in a hierarchical grid (which could have 3 or more levels).

I understand that the get_itemIndexHierarchical() returns a string representing the path and also how some recommend using the last part after the last underscore. But I have had no luck figuring out how to use it and all my iterations of code end up either blowing up with id or object is null or it selects the parent.

Current iteration of my code:

function ElementRowDblClick(sender, eventArgs) {

var grid = sender;

var MasterTable = grid.get_masterTableView();

var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];

debugger;

$find("<%= rgData.MasterTableView.ClientID %>").editItem(row);

}

Can anyone help point me in the right direction?

I have pondered using the string ("0:0_0:0_0") and parsing it to calculate a row index however it seems I would have to traverse child items or recursively search for an item to pass it to editItem()? I have set HierarchyLoadMode="Client" and GroupLoadMode="Client" although I'm not using groups anyway. And client settings are:

<ClientSettings AllowExpandCollapse="true" >

<ClientEvents OnRowDblClick="ElementRowDblClick" />

<Selecting AllowRowSelect="True" />

</ClientSettings>

I have trawled many forum postings but can't seem to find anything similar to what I want to achieve, i.e. putting the row I double click into edit, via editItem(), and not just the parent row.

Any help very much appreciated.

Postback on Check only

Is there a way to make it so the listbox only postbacks on check and not also on selection?

I have AutoPostBack="true" and OnItemCheck set to my server side function. It works great, but when you click on an item and not the check box, it posts back as well. Is there a way to stop that postback but still allow the checkbox check postback?
