Is it neccessary to rebind the Telerik ListView whenever its SelectedIndexChangedEvent is fired ?

Hi,
I have an unusual question regarding listview. I have used many controls like drop down , gridview etc but didn't find anything like to rebind the control whenever its selectedindexchanged event is fired?

But today when i was working with the Listview of which i was firing its SelectedIndexChanged event on item selection, what i noticed that the event runs successfully for the first time and details of the item selected is shown but as soon as some other item is selected, the event throws an error on the code where it accepts the item value - as shown below

ArgumentOutOfRangeException :
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Exception is thrown when :

ItemID = ItemListView.SelectedValue.ToString();

I Though of rebinding it in the event itself and the problem went away.
I am still confused that why i should rebind listview in the SelectedIndexChanged event.

Thanks for reading and any usefull info will be appreciated ..!!

ColumnEditorID and GridNumericColumnEditor

Hi,

I'm trying to set ColumnEditorID to GridNumericColumnEditor in radgrid (pop up edit mode).

So:

                     <telerik:GridBoundColumn DataField="TRNO_ID" DataType="System.Decimal" HeaderText="ID"        
             ColumnEditorID="TRNO_ID_CE">           
            </telerik:GridBoundColumn>          

                     <telerik:GridNumericColumnEditor ID="TRNO_ID_CE" NumericTextBox-EnabledStyle-HorizontalAlign="Right"         
                                                runat="server" NumericTextBox-Width="75px">         
                                                <NumericTextBox ID="NumericTextBox1" runat="server">         
                                                    <NumberFormat DecimalDigits="2" />         
                                                </NumericTextBox>         
            </telerik:GridNumericColumnEditor>         

But in edit mode this field is displaying like normal textbox.

But when I set:

                    <telerik:GridTextBoxColumnEditor ID="TRNO_ID_CE" runat="server">         
                                                <TextBoxStyle BackColor="#edffc3" BorderColor="#ecbb0d" BorderStyle="Solid" ForeColor="#7fa822" />         
            </telerik:GridTextBoxColumnEditor>         

in edit mode this field has changed background (it's work).

Where is a problem?

Not Working: MasterTableView.GetItems(GridItemType.Header)

The function is returning no items. Following is a copy of my markup and code:

protected void Page_Load(object sender, EventArgs e)

{

RadGrid1.DataSource = GetDataSource();

RadGrid1.DataBind();

}

private DataTable GetDataSource()

{

...

}

private void AddGroupHeadersToGrid()

{

GridItem[] header = RadGrid1.MasterTableView.GetItems(GridItemType.Header);

//GridTHead head = ((GridTHead)header[0].Parent.Controls[0].Parent);

GridHeaderItem newHeaderItem = new GridHeaderItem(RadGrid1.MasterTableView, 0, 0);

newHeaderItem.Cells.Add(new GridTableHeaderCell());

newHeaderItem.Cells[0].Text = "I'm a header.";

//head.Controls.AddAt(0, newHeaderItem);

}

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

AddGroupHeadersToGrid();

}

The markup looks like this:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false"

onprerender="RadGrid1_PreRender">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="Question" DataField="Question" UniqueName="Question">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Score" DataField="MTDScore" UniqueName="MTDScore">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Area" DataField="MTDArea" UniqueName="MTDArea">

<telerik:GridBoundColumn HeaderText="Score" DataField="QTDScore" UniqueName="QTDScore">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Area" DataField="QTDArea" UniqueName="QTDArea">

<telerik:GridBoundColumn HeaderText="Score" DataField="YTDScore" UniqueName="YTDScore">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Area" DataField="YTDArea" UniqueName="YTDArea">

</Columns>

</MasterTableView>

</telerik:RadGrid>

I would really appreciate if somebody can tell me what I'm doing wrong here!

$find not working with IE 8

Hi,

I am trying to reference a radTextBox through javascript to capitalize its value on blur and keypress event.
However, $find(client-Side-Object-Name) returns null in IE whereas it works fine in firefox (3.5.5).

The version of our telerik is 2008.3.1314.35

    
            <telerik:RadScriptBlock ID="radScriptBlock" runat="server"> 
        
                <script type="text/javascript"> 
        
                    AddPageLoadHandler(function() 
        
                    { 
        
                        AutoCapitaliseFirstChar('<%= FirstNameTextBox.ClientID %>'); 
        
                    }); 
        
                </script> 
        
                </telerik:RadScriptBlock>

    
            function AddPageLoadHandler(fn) 
        
            { 
        
                Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(fn); 
        
            }

    
            // not created dynamically 
        
            <telerik:RadTextBox runat="server" ID="FirstNameTextBox" />

    
            // These client-side functions auto-capitalises text in RadTextBox as user enters it 
        
            // The conversion is done after a short timeout to avoid interfering with normal onfocus behaviour 
        
            function AutoCapitaliseFirstChar(radTextBoxClientId) { 
        
                var radTextBoxClientObject = $find(radTextBoxClientId); 
        
                // here radTextBoxClientObject is null for IE but not for firefox 
        
                // so it works fine with firefox not with IE 8 
        
                // This converts the text when field loses focus 
        
                $(radTextBoxClientObject.get_element()).blur(function() { 
        
                    setTimeout(function() { 
        
                        var val = radTextBoxClientObject.get_value(); 
        
                        radTextBoxClientObject.set_value(val.substring(0, 1).toUpperCase() + val.substring(1)) 
        
                    }, 200); 
        
                }); 
        
                // Except in Safari, convert the text as it is typed 
        
                // (in Safari this is incompatible with the field autocomplete behaviour) 
        
                if (!$.browser.safari) { 
        
                    $(radTextBoxClientObject._textBoxElement).keypress(function() { 
        
                        setTimeout(function() { 
        
                            var val = $(radTextBoxClientObject._textBoxElement).val(); 
        
                            radTextBoxClientObject.set_value(val.substring(0, 1).toUpperCase() + val.substring(1)) 
        
                        }, 200); 
        
                    }); 
        
                } 
        
            }

Any ideas would be appreciated,

regards,

Toby
