Questions on UI for ASP.NET AJAX Forum

I have found while working with the RadGrid that when AllowKeyBoardNavigation is set to true all keyboard navigation events are being captured whether focus is in the grid or not. Not sure if I am going crazy or not, or if there is some other solution.
Here is a simple example that I have duplicated in IE and chrome.

Place a RadTextBox and RadGrid on a form setting the client setting AllowKeyBoardNavigation="True". Also in my testing I am using a masterpage.

<asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

</telerik:RadAjaxManager>

<telerik:RadTextBox ID="RadTextBox1" runat="server">

</telerik:RadTextBox>

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None"

onneeddatasource="RadGrid1_NeedDataSource">

<ClientSettings AllowKeyboardNavigation="True">

</ClientSettings>

<MasterTableView>

<CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False">

</FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

</asp:Content>

When you open the page and the grid is filled put focus and type something in the textbox and attempt to use the back and forward buttons on your keyboard. In my testing focus leaves the textbox and is placed immediately on the grid when one of these keys is pressed. Is this by design or a bug?

Batch update in VB

I'm trying to use the code below to perform a batch update in a RadGrid but I'm getting the error below. I was able to get this to work fine in C# but now I need to get it to work in VB.net

Protected Sub gvGrossPayroll_ItemCommand(ByVal sender As Object, ByVal e As GridCommandEventArgs)

If e.CommandName = "UpdateAll" Then

For Each editedItem As GridEditableItem In gv_grosspayroll.EditItems

Dim newValues As New Hashtable()

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem)

Update_PayrollRecord(editedItem.GetDataKeyValue("ID"), Convert.ToDecimal(newValues("PayrollAmount")))

Next

End If

gv_grosspayroll.Rebind()

End Sub

Error:

Selection out of range
Parameter name: value

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Insert row in RadGrid with Edit Form - how to put the edit form at the bottom of the grid?

Hello everyone!

I've been trying out inserting and editing with the RadGrid's edit form ("in" the Grid), and I'm very pleased with the results so far. Here's a sample of what I've achieved:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<div style="width: 500px;">

<telerik:RadGrid ID="RadGrid1" runat="server" OnInsertCommand="RadGrid1_InsertCommand"

OnNeedDataSource="RadGrid1_NeedDataSource" OnUpdateCommand="RadGrid1_UpdateCommand"

OnItemCommand="RadGrid1_ItemCommand">

<MasterTableView AutoGenerateColumns="false" CommandItemDisplay="Bottom">

<Columns>

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

</telerik:GridBoundColumn>

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

</telerik:GridBoundColumn>

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

</telerik:GridBoundColumn>

<telerik:GridEditCommandColumn UniqueName="EditCommandColumn">

</telerik:GridEditCommandColumn>

</Columns>

<EditFormSettings EditFormType="Template">

<FormTemplate>

<table>

<tr>

<td class="textb">

Number

</td>

<td>

<telerik:RadNumericTextBox ID="RadNumericTextBoxNumber" runat="server" Text='<%# Bind("Number") %>'

NumberFormat-DecimalDigits="0" DataType="System.Int32">

</telerik:RadNumericTextBox>

</td>

</tr>

<tr>

<td class="textb">

Title

</td>

<td>

<telerik:RadTextBox ID="RadTextBoxTitle" runat="server" MaxLength="1024" Text='<%# Bind("Title") %>'>

</tr>

<tr>

<td class="textb">

</td>

<td>

<telerik:RadTextBox ID="RadTextBoxDescription" runat="server" MaxLength="1024" TextMode="MultiLine"

Text='<%# Bind("Description") %>'>

</telerik:RadTextBox>

</td>

</tr>

</table>

<br />

<asp:Button CommandName="Cancel" ID="Button1" runat="server" Text="Cancel"></asp:Button>

<asp:Button ID="Button2" Text="OK" runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>' />

</FormTemplate>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

</div>

And the code-behind:

protected RegistrationLine DefaultRegistrationLine()

{

RegistrationLine dr = new RegistrationLine();

dr = new RegistrationLine();

dr.Number = 0;

dr.Title = "";

dr.Description = "";

return dr;

}

protected class RegistrationLine

{

public int Number { get; set; }

public string Title { get; set; }

public string Description { get; set; }

}

protected void Page_Load(object sender, EventArgs e)

{

if (!this.IsPostBack)

{

tempListRegistrationLines = RadGridBindStartUpData();

}

protected static List<RegistrationLine> tempListRegistrationLines;

private List<RegistrationLine> RadGridBindStartUpData()

{

List<RegistrationLine> list = new List<RegistrationLine>();

RegistrationLine rl;

rl = new RegistrationLine();

rl.Number = 1;

rl.Title = "A";

rl.Description = "aaa";

list.Add(rl);

rl = new RegistrationLine();

rl.Number = 2;

rl.Title = "B";

rl.Description = "bbb";

list.Add(rl);

rl = new RegistrationLine();

rl.Number = 3;

rl.Title = "C";

rl.Description = "ccc";

list.Add(rl);

return list;

}

protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

RadGrid1.DataSource = tempListRegistrationLines;

}

protected void RadGrid1_InsertCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

List<RegistrationLine> table = tempListRegistrationLines;

RegistrationLine newRow = new RegistrationLine();

RadTextBox rtb;

rtb = (RadTextBox)editedItem.FindControl("RadTextBoxTitle");

newRow.Title = rtb.Text;

rtb = (RadTextBox)editedItem.FindControl("RadTextBoxDescription");

newRow.Description = rtb.Text;

RadNumericTextBox number = (RadNumericTextBox)editedItem.FindControl("RadNumericTextBoxNumber");

newRow.Number = number.Value.HasValue ? Convert.ToInt32(number.Value.Value) : 0;

table.Add(newRow);

}

protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

int idx = e.Item.ItemIndex;

List<RegistrationLine> table = tempListRegistrationLines;

table.RemoveAt(idx);

RegistrationLine newRow = new RegistrationLine();

RadTextBox rtb;

rtb = (RadTextBox)editedItem.FindControl("RadTextBoxTitle");

newRow.Title = rtb.Text;

rtb = (RadTextBox)editedItem.FindControl("RadTextBoxDescription");

newRow.Description = rtb.Text;

RadNumericTextBox number = (RadNumericTextBox)editedItem.FindControl("RadNumericTextBoxNumber");

newRow.Number = number.Value.HasValue ? Convert.ToInt32(number.Value.Value) : 0;

table.Insert(idx,newRow);

}

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

string strCommand = e.CommandName;

if (strCommand == RadGrid.InitInsertCommandName)

{

// prepare for insert: default data

e.Canceled = true;

RegistrationLine rl = DefaultRegistrationLine();

e.Item.OwnerTableView.InsertItem(rl);

}

if (strCommand == "Edit")

{

GridEditFormItem editItem = e.Item as GridEditFormItem;

// nothing

}

However, I would like to have the insert form at the bottom of the Grid, instead of at the top. So my question is: is there any easy way to do this?

Thanks in advance for your suggestions.

RadGrid GroupBy Problem

I am using a RadGrid and doing group by with jobstateName but when I bind the data my last stage comes first with users.
I also don't want that in my header it appears that I am grouping my data with jobstatename because i don't want it to show to the end-user. Because jobstatename appears at the top of the grid and it looks very ugly in my scenario. Any help would be really appreciated.

For example

stage4
john
harry

stage3
some users here ...

stage2
some users here ...

stage1
some users here ...

  <telerik:RadGrid ID="gvUserJobMapping" runat="server" PageSize="10" AllowSorting="True"
   GroupingEnabled="true" AllowPaging="True" ShowGroupPanel="True" AutoGenerateColumns="False"
   GridLines="None" CssClass="gridviewSpacing gvJobStates">
   <PagerStyle Mode="NumericPages"></PagerStyle>
   <MasterTableView Width="50%" GroupLoadMode="Client" TableLayout="Fixed">
   <GroupByExpressions>
   <telerik:GridGroupByExpression>
   <SelectFields>
   <telerik:GridGroupByField FieldName="JobStateName" FieldAlias="JobStateName" HeaderText="Job Stages"
   FormatString="{0:D}"></telerik:GridGroupByField>
   </SelectFields>

Displaying 2nd & 3rd levels

Hi,

I have a basic radmenu working fine with 3 levels of data:

Item
- Item
   - Item
   - Item
   - Item
Item
- Item
   - Item
   - Item
   - Item

What i want todo visually is display the top level items as normal but almost group the 2nd & 3rd levels together (within the dropdown) eg:

The dropdown would display items as:

Level 2 Level 2
Level 3 Level 3
Level 3 Level 3

Is this possible ?

Cheers

Luke

Rename and delete file with CustomFileSystemProvider

Hello, with this (http://www.telerik.com/support/kb/aspnet-ajax/fileexplorer/physical-paths-and-different-content-types.aspx) custom provider I can't delete and rename files. I fixed it:

public override string GetPath(string path)

{

// First add the '~/' signs in order to use the VirtualPathUtility.GetDirectory() method ;

/*string PathWithTilde = "~/" + path;

string virtualPath = VirtualPathUtility.GetDirectory(PathWithTilde);

virtualPath = virtualPath.Remove(0, 2);// remove the '~' signs

return virtualPath;*/

string virtualPath = "";

if (Path.GetFileName(path).Length > 0)

virtualPath = path.Replace(Path.GetFileName(path), "");

return virtualPath;

}

It's correct?
