show an image in a grid cell based on the grid cell value?

Hi,

Is it possible to display an image in a grid cell based on the grid cell value. For example, if the cell value is say 'True/false', show a thumbs up or a thumbs down image.

Are there any inbuilt methods for doing this?

Or do we need to manipulate in the item_databound event?

Will there be performance issues if this is done for say (10 columns * 100 rows), i.e approximately 1000 cells?

Thanks,
Saravanan

3. when click "save all", update all edited rows

What I did

            GridTemplateColumn assResult = new GridTemplateColumn();  
        
            this.RadGridGradingBatchEntry.MasterTableView.Columns.Add(assResult);  
        
            assResult.DataField = "UniqueDateField";  
        
            assResult.UniqueName = "UniqueDateField";  
        
            assResult.SortExpression = "UniqueDateField";  
        
            assResult.HeaderText = "UniqueDateField";  
        
            assResult.SortExpression = "UniqueDateField";  
        
            assResult.DataType = System.Type.GetType("System.Int32");  
        
            assResult.Resizable = true;  
        
            assResult.ItemStyle.Wrap = true;  
        
            assResult.ItemStyle.Width = 15;  
        
            assResult.ItemTemplate = new MyTemplate()  // Mytemplate returns implements Itemplate and I created this class according to one of forums I found here.

for 2

    
            protected void RadGridGradingBatchEntry_PreRender(object sender, System.EventArgs e)  
        
                {  
        
                    foreach (GridDataItem item in RadGridGradingBatchEntry.Items)  
        
                    {  
        
                        item.Edit = true;  
        
                        RadGridGradingBatchEntry.Rebind();  
        
                    }  
        
                }

for 3

    
            protected override void RaisePostBackEvent(IPostBackEventHandler source, string eventArgument)  
        
                {  
        
                    base.RaisePostBackEvent(source, eventArgument);  
        
                    if (source is RadGrid)  
        
                    {  
        
                        string[] postBackEventArgumentData = eventArgument.Split(':');  
        
                        switch (postBackEventArgumentData[0])  
        
                        {  
        
                            case "SaveAll":  
        
                                foreach (string l_EachItem in postBackEventArgumentData[1].Split(','))  
        
                                {  
        
                                    if (!(l_EachItem == ""))  
        
                                    {  
        
                                        GridItem item = (GridItem)((Table)RadGridGradingBatchEntry.MasterTableView.Controls[0]).Rows[int.Parse(l_EachItem)];  
        
                                        GridEditableItem editedItem = (GridEditableItem)item;  
        
                                        Hashtable newnewValues = new Hashtable();  
        
                                        item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);  
        
                                    }  
        
                                }  
        
                                break;  
        
                        }  
        
                    }  
        
                }

Now problem is that when I look up newValues, all dynamically created columns are not visible but only columns that have been specified as bound column are available to access.

Your help will be appreciated as always,

Toby

Need to update text in RadGrid fields

I have a RadGrid set up to do automatic inserts and updates. I get the edit links, which open the edit form, as it should. I can enter and retrieve the new values with no problems. However, because we are connecting to a legacy mainframe application, we have to send ALL the on screen data in one message; I can't just do a simple update of the single record I'm editing.

In order for the pop-up editing to work in the grid I'm using the OnNeedDataSource event. I believe this is causing the problem.

I have code behind the Update command for this grid (rgdDetails) to update the selected row's "ItemClass" cell. I know it's hitting this code, because the "Record Updated" message is being displayed, but the text in the cell is not being changed. Am I not handling the OnNeedDataSource event properly? Is it reloading and overwriting the data that I want to change with the original data? Or am I doing something incorrectly when trying to enumerate the cell I want to change?

        Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)
        editedItem = e.Item
        editedItem("ItemClass").Text = "Testdata"

       rgdDetails.MasterTableView.ClearEditItems()
        Master.MessagePanel.InfoMessage("Record Updated")

Here is a section of the OnNeedDataSource code. It's opening a query and setting the datasource for the grid.

        Dim pDate As String = _Control.SelectedDate.ToString
        Dim pStore As String = _Control.SelectedStore
        Dim pTerm As String = _Control.SelectedTerminal
        Dim pTran As String = _Control.SelectedTransaction

        If (pStore <> "0") And (pTerm IsNot Nothing) And (pTran IsNot Nothing) And (pTran <> "") Then
            Dim ds1 As DataSet = TransDetailDAL.GetTranItemsDetail(pDate, pStore, pTerm, pTran)
            rgdDetails.DataSource = ds1

            Dim dr As DataRow = TransDetailDAL.GetTranHDRDetail(pDate, pStore, pTerm, pTran)

Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'.

This is how I formed my control

<telerik:RadBinaryImage ID="imageThumbnail" runat="server" DataValue='<%# Eval("imageThumbData") %>' ImageUrl="~/imageLibrary/common/nopic.gif" Width="125" Height="125" />

When I run the application I get an error saying

Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'.

Isnt the imageURL suppose to handle this null case? How can I fix it?

Thank you.

Show Code in New Window

If you go to the online demos, each page includes various code files. In the area that the content of these files is displayed the is a link in the upper right corner which reads "Show code in new window".

Click on this link and a new window does, in fact, open. Now, go to another of the files in the original page and click on the same link.

Disappointed? I was. Instead of now having 2 windows with different files displayed in them, the new window that was opened the first time I clicked on the link had its content replaced with the 2nd file.

A quick look at the scripts suggests that a window called 'codeViewer' is always used. Can you not just use '_blank'?
