I have attached two images to this post. They are screenshots of Chrome vs Opera for the code mentioned above. The window that I am showing in the screenshots opens up smaller than anticipated in Opera. Other RadWindows I have open larger than anticipated.

I did some searching on the Telerik forums, and found this link from 2009. I am not sure if this discussion is still applicable current day, however. If so, does Telerik have any suggestions on best practice for handling this scenario?

Cheers,

Sean

Need dynamic ConfirmText on programmatically added column

Hello,

If need to create a 'delete column' programmatically due to authorization constraints ( I need to show or hide the column based on privilege) that prompts for delete but I would rather it say 'Delete client John Smith?' rather than 'Delete this client?' i.e. I would like to personalize it for each row. This is what I have now:

    
             if (((UserProfile)Session["_userProfile"]).IsAuthorized("Client - Delete"))  
        
                    {  
        
                        _buttonColumn = new GridButtonColumn();  
        
                        radGridClients.MasterTableView.Columns.Add(_buttonColumn);  
        
                        _buttonColumn.ButtonType = GridButtonColumnType.ImageButton;  
        
                        _buttonColumn.ConfirmDialogType = GridConfirmDialogType.Classic;  
        
                        _buttonColumn.ConfirmText = "Delete this client?";  
        
                        _buttonColumn.HeaderText = "Delete";  
        
                        _buttonColumn.HeaderStyle.Width = 40;  
        
                        _buttonColumn.CommandName = "Delete";  
        
                        _buttonColumn.ImageUrl = "./images/delete.gif";  
        
                    }

When using a declarative template column I could do an "Eval" to get the cuurent row on the databaind using a template column like so:

    
                        <telerik:GridTemplateColumn   
        
                            UniqueName="TemplateDeleteColumn" 
        
                            HeaderText="Delete" 
        
                            HeaderStyle-Width="60" > 
        
                            <ItemTemplate> 
        
                                <asp:ImageButton ID="DeleteButton" OnClick='<%# Eval("NameLast2First", "return confirm(\"Delete all record of the Client {0} from the database?\");" ) %>'  runat="server"  ImageUrl="./images/delete.gif" CommandName="Delete"  /> 
        
                            </ItemTemplate> 
        
                        </telerik:GridTemplateColumn>

How would one create a dynamic ConfirmText when creating the column programatically?

Thanks
Jonathan

Slider not recognizing colspan

We have a slider with a colspan specification. If we make the width="100%", it only makes it as wide as the first column. If we do a width="400px", we run into problems with column widths as we don't know how wide the four columns will be.

I expect the "100%" to make it as wide as the four columns. How can we make it 100% or is a code fix needed as to me, it appears to be a bug in the control. Here is the code snippet:

<tr>

<td>Off</td>

<td colspan="4">

<telerik:RadSlider ID="RunAssetRS" runat="server" width="100%" OnClientValueChanged="RunAssetRS_OnValueChanged" OnClientLoad="RunAssetRS_OnValueChanged" ShowDecreaseHandle="false" ShowIncreaseHandle="false" ></telerik:RadSlider>

</td>

<td>990</td>

</tr>

Creating a custom Group Template

Hi guys,

I have a Gridview wich is grouped by a column.

Design

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldAlias="TL" FieldName="TargetLanguageCode" FormatString="{0:D}"

HeaderValueSeparator=": " HeaderText="">

</telerik:GridGroupByField>

<telerik:GridGroupByField FieldAlias="Flag" FieldName="FlagIcon" FormatString="{0:D}"

HeaderValueSeparator=": " HeaderText="">

</telerik:GridGroupByField>

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="TargetLanguageID" SortOrder="Descending"></telerik:GridGroupByField>

<telerik:GridGroupByField FieldName="FlagIcon" ></telerik:GridGroupByField>

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

On the Grid ItemDataBound event I delete all the controls from the Group template and add a label and image

protected void gridGeneratePackages_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridGroupHeaderItem)

{

GridGroupHeaderItem item = e.Item as GridGroupHeaderItem;

Image img = new Image();

img.ImageUrl = ((DataRowView)e.Item.DataItem)[1].ToString();

img.Width = 16;

img.Height = 12;

Label lbl = new Label();

lbl.Text = ((DataRowView)e.Item.DataItem)[0].ToString(); ;

lbl.Style.Add("margin-left", "3px");

item.DataCell.Controls.Clear();

item.DataCell.Controls.Add(img);

item.DataCell.Controls.Add(lbl);

}

This works perfectly when loaded, but when I click on a Grid Arrow to expand a Parent/Child, my added controls are removed and the ones in the design appears.

Any idea if there is a better solution ?

Thanks.

RadEditor: Value Cannot Be Null Parameter: child error after upgrade to Q2 release

After upgrading to the Q2 release today, I get the error below as soon as I hit the page with the RadEditors. It does not hit any break points. It happens in both Release and Debug mode.

I have multiple RadEditors on the page sharing a single toolbar using the ToolBarProviderID property. When I stop sharing the toolbar, I do not get the error.

At one time, the Stack Trace referenced a method with a name like "Ribbon" something. I believe it has to do with the new ribbon functionality.

I do not get this error when I use the Q1 release.

Please let me know if there is a workaround for the problem.

Changing column types?

Hi,

I'm using the same RadGrid control for several different datasources, and thus I'd like to have it add columns automatically as it is now. However I'm having a problem converting specified int columns into checkbox columns (the values are all 0 and 1). Is there any way to cast/change the column from a GridNumericColumn into a checkbox column, or do you have any advice on how to resolve the situation?
