Hi! I want to change color of text in each grid row, based on a datakey value. It works fine in all columns but for the text in gridHyperLinkColumn. What to do? I have a custom skin defined on the grid, and this is what I do in code behind. Please can you help me?

    
            void GridMyTasks_ItemCreated(object sender, GridItemEventArgs e)  
        
                    {  
        
                        try 
        
                        {  
        
                            if ((e.Item.ItemType == GridItemType.Item) || (e.Item.ItemType == GridItemType.AlternatingItem))  
        
                            {  
        
                                if (e.Item.DataItem != null)  
        
                                {  
        
                                    string dueDate = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ActivityDueDate"].ToString().Trim();  
        
                                    if (dueDate != "")  
        
                                    {                              
        
                                        DateTime date = Convert.ToDateTime(dueDate);  
        
                                        if (date<DateTime.Today)  
        
                                        {                                  
        
                                            e.Item.ForeColor = System.Drawing.Color.Red;  
        
                                        }  
        
                                        else if (date < DateTime.Today.AddDays(10))  
        
                                        {                                  
        
                                            e.Item.ForeColor = System.Drawing.Color.Orange;  
        
                                        }  
        
                                    }  
        
                                }  
        
                            }  
        
                        }  
        
                        catch (Exception ex)  
        
                        {  
        
                            ShowLabel(ex);  
        
                        }  
        
                    }

                } 
        
            }

Basically what I want: When user expands a region and clicks on "Add child record" (to add a child record to that region), the dd_Regions drop down column is automatically set to the value of the parent record.

when i debug, and step through the RadGrid1_ItemDataBound method, the parentItem variable is populated correctly, and has the ID that I am expecting. But editor.DropDownListControl comes back empty (Items.Count = 0). direct casting to a DropDownList returns the same (empty count).

Any help appreciated!

thanks in advance

Update row on row exit

I have a hierarchal grid with two levels (master and details). When a master level record is expanded all detail records are automatically put into Edit mode. As the user tabs through each detail record I would like to save their work automatically (no mouse clicks, no enter key). When the user exits the row the record is saved.

This is going to be a high speed data entry application and mgt does not even want to display the update/cancle buttons on each detail record.

What would be the best method for achieving this?

How do you localize RADGrid headers ?

If I have a RADGrid, such as:

                            <telerik:RadGrid runat="server" ID="radGrid" PageSize="25"         
                        AllowPaging="true"          
                        AllowSorting="true"          
                        AutoGenerateColumns="false" >         
                        <PagerStyle Mode="NextPrevNumericAndAdvanced" />         
                        <MasterTableView>         
                            <Columns>         
                                <telerik:GridBoundColumn DataField="ItemNumber" HeaderText="Item number" AllowSorting="true"  />         
                                <telerik:GridBoundColumn DataField="Name" HeaderText="Name" />         
                                <telerik:GridBoundColumn DataField="ShortDescription" HeaderText="Description" />         
                                <telerik:GridBoundColumn DataField="Price" HeaderText="Price" />         
                            </Columns>         
                        </MasterTableView>         
                    </telerik:RadGrid>         

What is the preferred way to localize the HeaderText values ? (Say, if the page is being shown in the Danish culture, I would like to display the danish names as column headers, instead of english ones).

I possible, I would like to do this in the markup. I already have a helper method such as:

                    HeaderText="<%= Translate.Text("ItemNumber") %>"         

But if I try to do this on a Column, I get a parser error: "Literal content ('<telerik:GridBoundColumn DataField="ItemNumber" HeaderText="') is not allowed within a 'Telerik.Web.UI.GridColumnCollection'."

Telerik radGrid demos: Is there any reason you don't explicitly disable vewState for every control in the editTemplate?

q2 2009

hiya,

I can't see any reason why you wouldn't explicitly disable viewstate for every control in a radGrid's editTemplate in the demos.
Let me know if there is a good reason, otherwise, disable it in your demos, the performance will benefit.

If this helps, you know who to credit the points to....

filtering options customizable

Hi,
Please could you tell me if the fitlering buttons are customizable (i.e. can you just show a subset of them and can you rename the options)

Thanx

Suppress ClientEvents on Page_Load

Hello!

I have an ASP.NET-Button shipped with VS. This button is responsible for saving the data the user enters in the form. When the Page is loaded, the button should be disabled. Then I have other controls (standard VS controls), where I have "linked" the client-side onpropertychange() event. When a user for example fills out a javascript-enabled textbox, the javascript-function will enable the Save-Button. Everything is fine.

When I now - for example - use RadTextBox and link the ClientEvents-OnValueChanged with the same javascript-function, the page loads and I can see, that the Save-Button is automatically enabled?!?

Is it possible, that RadControls do not fire javascript-events on Page_Load? Are there any workarounds?

Bye

Michael
