Row does not expand when visible property of image in itemtemplate set to false

I have a grid with a detail table. I can expand each row and see the cooresponding detail record. I have a custom procedure on the grid event OnItemDataBound. I wanted to turn a couple images on or off based on a value in the database as well has build a URL for another hyperlink control. When the image control visibility is set to false or the navigateurl on the hyperlink is set, the row will not expand. I have verified that the page is posting back and making a call to the database when I attempt to expand the row. Any other row that I did not touch the image or hyperlink control still expands without a problem.

Thanks in advance.

Question on returning values to a parent window.

Hi,

I am basing my code off of the sample you have here:
http://demos.telerik.com/aspnet-ajax/window/examples/dialogreturnvalue/defaultcs.aspx

In your sample, on the aspx page for "Dialog2.aspx" is a javascript function:

function returnValue()

{

//get the RadComboBox's selected item's text

var combo = $find("<%= RadComboBox1.ClientID %>");

var selectedCapital = combo.get_text();

//Get a reference to the parent page (Default.aspx)

var oWnd = GetRadWindow();

//get a reference to the second RadWindow

var dialog1 = oWnd.get_windowManager().getWindowByName("RadWindow1");

// Get a reference to the first RadWindow's content

var contentWin = dialog1.get_contentFrame().contentWindow

//Call the predefined function in Dialog1

contentWin.populateCityName(selectedCapital);

//Close the second RadWindow

oWnd.close();

}

This line here, works great, but I need to try to modify:

contentWin.populateCityName(selectedCapital);

instead of calling a function (in this case "populateCityName") I want to be able to set the control's value directly.
Is this possible?
So instead of the above line of code, I would like to do something like:

contentWin.document.getElementById("cityName").value = "hello";

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

            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)
