Hi,
I am try to update all grids in our project to have consistency in look and feel.
I am looking for guidance for setting width of RadGrid and Columns. Found this link http://www.telerik.com/community/forums/aspnet/grid/best-practice-for-grid-and-column-widths.aspx but it does not exist now. Is there any other resource available?

Thanks

Hi all,

I'd like to reorder my edit column to put it on the far right of my grid.

My radGrid is generated like this :

<MasterTableView>
<Columns>   
<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" ><ItemStyle CssClass="MyImageButton" width="20" /></telerik:GridEditCommandColumn>
</Columns>
</MasterTableView>

Then I add up dynamically columns in the even NeedDataSource.

The problem is, My edit column is on the far left and not on the far right. I've tried the following snippet without much success :

protected void radGridTranslation_DataBound(object _sender, EventArgs _event)
{
    GridColumnCollection l_columns = radGridTranslation.MasterTableView.Columns;
    GridColumn l_editColumn = l_columns.FindByUniqueName("EditCommandColumn");
    if (l_editColumn != 
    {
        l_editColumn.OrderIndex = 
    }  
}

I've found this example :http://www.telerik.com/help/aspnet-ajax/grid-reordering-columns.html

But I don't want to have to use a script to change anything. I should be able to do it right in my Code behind.

Could you help me please ?

My Grid expands outside my div container whenever I click Edit or Add New Record. How can I keep the grid inside the div? It doesn't look good when it goes outside the div. The div class name is WebpageManagementBox. The grid also has a class name of  webpageManagementGrid. I have attached a picture of what it looks like.

Here is the markup for the div and grid:

Here is the css for the div and the grid.

Hi,

I am trying to implement hierarchical grid. I am trying to refresh data in hierarchical RadGrid.  RadGrid is working fine when all rows are in collapsed mode.  Where as I am getting "Specified argument was out of the range of valid values." when the one or more nested tables are in expanded mode.
I am getting this error even before Page_Load event is fired.  What could be the possible reasons.

Thanks in advance,
Gafoor.

I cant get rid of the Social Media/Share Button on the Media player.

I tried to set visible and disable fields of the  TitleBar-ShareButton properties accordingly (False and True)

Still displays.    Please help

I am able to check all the checkboxes. But When I tried to retrieve all the checked boxes, checked, I am able to get the checkboxes ticked only in the first page.
other page value are not getting retrieved using the code:

for (int i = 0; i < rdNew.Items.Count; i++)
{
CheckBox chkSelected = (CheckBox)rdNew.Items[i].FindControl("chkSelected");
String Id = rdNew.Items[i]["id"].Text;

if (chkSelected.Checked && chkSelected != null)
{
if (list.Count == 0)
{
list.Add(Id);
}
}
}
I am not getting the total list, of the users checked.

I am creating a batch grid.  One of the cells in this grid is telerik:GridTemplateColumn ("Value" in the code below)  The EtidItemTemplate contains different objects.  Depending on the selected field type, only one of the objects is displayed.  So, if the field type is date, a calendar will be displayed and the other types - hidden.

Here are the issues I am coming across at the moment:
1. if the field type is text, the first time the user enters text into the box and moves out, the selected value is displayed as blank.  If I re-open the text box and enter the value once more, it shows up.
2. If field type is telerik:RadComboBox, I would like the ItemTemplate to display a comma delimited list of descriptions but the best I can do is a comma delimited list of IDs.  I need to be able to save the selection as list of IDs but display a list of descriptions to the user.
3. if I am editing an item that was saved earlier, the change is not processed.  I only see delete and insert being processed.

Here is the code for the aspx and code behind.
Thank you!

Hi I'm new here and I'm currently working with ASP.NET WebForms.

I had some issues trying to bind sources to a RadMediaPlayer that's inside a ASP Repeater:



The repeater source is provided by a stored procedure which is called in code-behind and then I use the "OnItemDataBound" event of the repeater to format each ItemTemplate. I'm doing all this steps because I'm working on a social network and I want to manage different posts (images,videos,songs,etc).

Here is the code-behind of the repeater event:  


The data bind of the repeater is working fine, for example the images binding is perfect but not the audio binding. You can see the player there but when you press play nothing happens, it seems like the source isn't there but i checked with the javascript console of google chrome and the source is there.

Here is also the static class that provides the path to the project local folder where the files (images,songs,videos,etc) are stored:


I hope you can help me.

Thanks in advance.

John.

Hi All,
I have a RadDatePicker control and I need to validate the date. The user must enter a valid date and I have to check the date is not greater that the DataTime.Now value.
I am trying to build a method to handle both cases and send the corresponding error message. It looks I do not have the choice to call a method from the RequiredFieldValidator control.
Do you have any suggestion to handle this case?
Thanks
Yuri.

I've got an expandable grid that I'd like to fill the child as a Floated Tiles ListView.  Each of the cells (or tiles) in the listview have set widths and are rows/records from a datasource.  Depending on the right margin it would be good if the cells could wrap, but if not a set number of columns would be fine.  Whats the best way to achieve this?  

+ Row 1
   [1][2][3][4][5][6]
   [7][8][9][10][11]
   [12][13][14][15]
   [16][17][18][19]
- Row 2
- Row 3

Reducing the width would wrap the cells
+ Row 1
   [1][2][3][4]
   [5][6][7][8]
   [9][10][11]
   [12][13]
   [14][15]
   [16][17]
   [18][19]
- Row 2
- Row 3

cheers
